Towel quilt: With its good air permeability, easy washing, easy storage and other characteristics, it has become a must-have bedding for many people in summer. The general specifications are 150×200cm and 180×220cm, mostly pure cotton products. The craftsmanship includes plain weaving, jacquard, broken files, cut pile and so on. There are also printing and plain colors. Towels will lose the floating hair after the initial washing customized multicolor hotels and families 100% cotton bath towel, which can be removed by washing 1-2 times, so do not wash with other clothes in the initial washing. It is unrealistic to wash large towels by hand. It is recommended to use a drum washing machine to wash the silk wool stall end program. Do not use a pulsator washing machine to wash directly. It is recommended that you look at the degree of shed hair on the towels at home. The floating hair will not fall too seriously. If the shed hair is smashed, it is estimated that you are using a top-opening pulsator washing machine at home. Nowadays, towels are all pursuing soft hand feeling soft bamboo microfiber hooded towel quotation. The softer the hand feeling, the more hair will be removed by washing with a pulsator. You can buy a laundry bag and put the towel in the laundry bag and wash it again. It will definitely not shed hair. Nowadays, many people think that the lint of the towel is the problem of towel quilt. They don't know that it is actually caused by the wear and tear of the washing machine at home. It is estimated that the hole will be broken in a few years after washing like this. The pulsator washing machine must be placed in the laundry bag to wash the towels and quilts. The drum washing machine is less abraded, and you can wash it directly when you hit the silk wool stall.

1. Firstly, use detergent correctly, master reasonable feeding time and temperature, understand the basic characteristics and usage of detergent, timely use dechlorinating agent to remove excess chlorine, and neutralize residual alkali with neutralizer ; 2. Avoid direct contact with pure cotton fabrics with strong acid or corrosive chemicals; 3. The sorting work before washing must be done, including the sorting of bath towel linen and the separation of sundries; 4. Be careful during the collection and transportation of bath purchase multicolor microfiber magic cooling towel to prevent secondary pollution and accidental tearing; 5. "Fatigue use" should be avoided, that is, washing multiple times a day, this will accelerate the shortening of bath towel life. It should have sufficient rest time, at least 24 hours or more, that is, after washing, rest for one day and use it the next day; 6. It is necessary to check the machine frequently to prevent secondary pollution and man-made damage, and the load should be appropriate (80%~85%) during washing. Too much or too little will affect the cleanliness and wear of the bath towel; 7. Before the washing operation, the machine should be empty to check whether there are sharp and iron debris in the machine drum; 8. It is necessary to classify the old and new bath polyester cool sports towel factory. The natural damage and abnormal damage of old bath towels should be treated separately, and the length of dehydration time should be different for different strengths of old and new bath towels. Control the loss of bath towels and extend the service life of pure cotton bath towels. Doing the above points can save the cost of bath towels and reduce the damage of bath towel products.

Composite geomembrane is developing rapidly in our country and is widely used. Composite geomembrane is a kind of anti-seepage material with fast construction speed, good waterproof effect and low investment cost. It is especially suitable for the anti-seepage of hilly reservoirs, plain reservoirs and old dams with small water storage depth. The curve intersection method is a calculation method of composite plastic geonet factory price thickness, which can be used to calculate the geomembrane thickness of the low-head earth-rock dam surface, the geomembrane thickness of the reservoir pool slab, and the geomembrane thickness of the concrete building repaired with the geomembrane. For earth-rock dams with medium and high water heads, after laying the composite geomembrane, the dam body will undergo large deformation, and the finite element stress-strain curve method based on stress-strain calculation should be adopted. This method can be applied to the design of composite geomembrane thickness under various conditions. The membrane in the composite geomembrane plays a role of impermeability, and the geotextiles on both sides play a role of stretching and protection. The thickness (density) and material of the geotextile have a great influence on stress and strain. Therefore, when selecting materials, the composite uniaxial plastic geogrid factory price needs to have an ideal stress-strain curve in addition to a higher ultimate tensile strength. The stress and strain of the dam foundation are related to the construction sequence and deformation characteristics of the dam material. If the composite geomembrane is laid after the dam is filled, only the strain value caused by water storage is calculated; if the dam material has a large creep deformation, the strain value caused by creep should be considered. Considering the construction technology and safety margin, the finite element stress-strain curve method is adopted, that is, the effect of composite geomembrane stiffness is not considered. This is feasible when the stiffness of the asphalt concrete face rockfill dam is much greater than the composite geomembrane. However, when the stiffness of the gravel material is not very high, ignoring the influence of the composite geomembrane stiffness will have a certain impact on the calculation results. The degree of influence is not only related to the real simulation model of the composite geomembrane, but also related to the laying relaxation of the composite geomembrane.

To choose a good towel, you can go through the following three steps: 1. Look at the label Qualified towel products should have standardized labels, which are mainly composed of 9 aspects, namely product name, executive standard, factory name and location, quality grade, fiber content, specification and model, washing mark, safety category, and certificate. Such as: safety category, divided into A (infant standard), B (adult standard) and C (non-direct skin contact wholesale all-purpose personalized instant cooling relief cool towel). Quality grade: excellent product, first-class product, qualified product. 2. Look at the appearance Good towels have fresh and bright colors, clear patterns, uniform loops, straight seams, and neat appearance. 3. Appreciate quality 1) Water absorption: Towels with good water absorption can be quickly absorbed by water droplets; for towels with poor water absorption, water droplets will form when water droplets go up. 2) Color fastness: Towels with good color fastness are still clear and bright after long time use; towels with poor color fastness are easy to fade and are harmful to the skin. 3) Hand feeling: high-quality towels are soft and flexible. Remember to dry the polyester cool sports towel factory to avoid harm to the skin. 4) Odor: A good towel has no peculiar smell. If there is a candle smell or ammonia smell, it means that the softener is excessive; if there is a sour smell, the PH value may exceed the standard; if there is a pungent smell, it means that a fixing agent containing formaldehyde is used, and free formaldehyde is precipitated.

In the process of repairing old water conservancy buildings, composite geomembrane is usually used as an impermeable material for the building. The splicing quality is the key to the success or failure of the composite geomembrane's anti-seepage performance. The splicing method is usually constructed by hot-melt welding. The membrane and the membrane are usually welded by a dual-drive self-propelled environmental geomembrane manufacturers welding machine. The overlap width of the weld is 10cm, and there is a 10mm wide cavity between the two welds. The cloth and the cloth are used Portable sealing machine, polyester thread T-shaped stitching. Note that before the formal welding, test welding should be carried out according to the climate characteristics of the construction area to determine the walking speed and welding temperature. During the construction process, the walking speed of the welding machine should be controlled at 0.8-1.2m/s, and the welding temperature should be 240-260℃ to ensure that the welding quality of the composite LDPE geomembrane manufacturers meets the design requirements. Before welding, it is best to lay a long wooden board under the seam of the geomembrane so that the welder can walk on a flat base surface to ensure welding quality. In addition to the quality of the material, to further improve the performance of the composite geomembrane, it is necessary to work hard during construction. In order to facilitate the construction and ensure the quality of splicing, the composite low cost textured geomembrane generally uses a wide width to reduce the amount of splicing on site. Before construction, according to the width of the material and the length of the site, the appropriate length should be cut in the factory, spliced ​​into blocks of the required size and rolled into a roll. Reserve about 10cm of non-composite layer on both sides (that is, the cloth and membrane are separated, called margins) for the lateral connection of the geomembrane. The damaged area of ​​the geomembrane when the weld is sheared mainly occurs in the weak part of the joint between the weld area and the geomembrane. Therefore, we should pay enough attention to the weld construction.

The composite geomembrane is a composite geomembrane that is pasted with geotextile on one or both sides of the film. Its form includes one cloth and one film, two cloths and one film, two films and one cloth, etc. The geotextile is used as the protective layer of the environmental geomembrane manufacturers to protect the anti-seepage layer from damage. In order to reduce ultraviolet radiation and increase anti-aging performance, it is best to use the buried method for laying. During construction, first use sand or clay with a smaller material diameter to level the base surface, and then lay the geomembrane. The geomembrane should not be stretched too tightly, and the part buried in the soil at both ends is corrugated, and finally a layer of about 10cm is laid on the geomembrane with fine sand or clay. Lay 20-30cm blocks of stone (or concrete prefabricated blocks) as a protective layer against erosion. During construction, try to avoid stones directly hitting the geomembrane. It is best to construct the protective layer while laying the membrane. The connection between the composite LDPE geomembrane manufacturers and the surrounding structures should be anchored by expansion bolts and steel plate battens, and the connection part should be coated with emulsified asphalt (2mm thick) to prevent leakage. The joint treatment of composite geomembrane is a key process, which directly affects the anti-seepage effect. The general joint methods are: ①Lap joint: the width of the lap should be greater than 15cm; ②Heat welding: suitable for a slightly thicker geomembrane base material, and the lap width of the weld is not less than 5CM. (Gluing is not recommended, soaking in water for a long time Easy to open glue, poor anti-seepage effect.) According to many years of practice, the thickness of the low cost textured geomembrane is not less than 0.25mm. If it is too thin, it may produce pores, and it is easy to be damaged during construction and reduce the anti-seepage effect. In the construction of geomembrane, special attention should be paid to ensure that the laying should not be too tight, not wrinkled, and the splicing must be firm. The construction should be strictly in accordance with the technical specifications, and the five quality barriers of preparation, laying, splicing, inspection and backfilling should be well maintained. Due to the good anti-seepage effect of the composite geomembrane.

The wholesale purchase of bath towels needs to pay attention to some details. The wholesale bath towels of good quality make customers not only comfortable and caring, but also feel very relaxed. Customers who are away from home hope to relax and wash away the fatigue during the bath. When buying towels and bath printed microfiber hooded towel price, you must have a pair of insights, and you also need to understand some related hotel towel knowledge. Mengfeisi Towel Factory only makes high-quality cotton hotel towels, working hard for the comfort and cleanliness of the hotel! Although bath towel wholesale does not occupy a very high share of hotel supplies, the frequency of use by guests is very large. Even the quality of a bath towel directly affects guests’ satisfaction with the hotel. Guest’s reputation is our golden cup, so When we purchase hotel bath 100% cotton hot promotional bath towel factory, we must not only be greedy for cheap. Buying inferior bath towels affects the reputation of the hotel, but it is a big deal. So how to buy bath towel wholesale? 1. Wholesale bath towels first look at the price and the weight As the saying goes, the first-class price is the first-class goods, especially now that the price of cotton is particularly high, the many patterns polyester printed jacquard beach towel factory price that are much lower than the market price must be inferior towels, and the gram weight, as long as it is 3% lower than the specified weight, it must be Manufacturers are cutting corners to reduce costs. 2. The wholesale texture of bath towels must be pure cotton The raw materials of Mengfeisi products are made of first-class 100% pure cotton and imported Pakistani cotton, which are durable, high in pure whiteness, good hand feeling, bright color and good water absorption. 3. Wholesale bath towels have better water absorption High-quality towels have a soft feel, fluffy and elastic in the hand. If a good-quality towel is dripped with water droplets, it can be quickly absorbed. If it is used to wipe hands and face, it can quickly dry the water and remove the dust; while the inferior towel It is slippery on the face, does not absorb water and does not decontaminate.

Jacquard towel is an item that everyone uses every day, and it is used every day, which makes it seem too ordinary and too usual. People often neglect her health, and the selection, use and placement of 100% cotton comfortable animal hooded towel are also too arbitrary. Up. It is this kind of randomness that will bring many unnecessary dangers to our health. After a period of time, the jacquard towel will become very hard and rough, not as soft as it was at the beginning. How can the jacquard towel stay soft? Pour the rice-washing water into the pot, put the jacquard towel in it and cook it. After it is boiled, cook it for a while. By doing this, the jacquard towel will become white, softer, thicker than the original, and will have a light rice fragrance. Put the jacquard towel in the hot water of the scrubbing liquid, boil or scald for 5 minutes, and then wash it while it is hot. Jacquard towels are often washed and boiled for a few minutes with soap, washing powder or lye at regular intervals to prevent hardening. When boiling, the jacquard towels should be fully immersed in water to avoid oxidation in contact with the air and reduce softness. When washing the kids hooded cotton cartoon poncho towel price list, put the jacquard towels in a thick soap, vinegar water or alkaline water and boil them for a moment. When boiling, the soap should swallow the jacquard towels. Then rinse with clean water and warm water several times in sequence, and dry it in a ventilated place with water. After drying, the jacquard towel will recover and become soft. The requirement is that the jacquard towel cannot be exposed to the sun for a long time, and it is usually better to dry it naturally in a ventilated place. Scientific disinfection of jacquard towels: first boil the jacquard towels in boiling water for 10 minutes, then wash them with a pan, and then wash them thoroughly with clean water, and finally fold the jacquard towels into the microwave oven and heat for 5 minutes. The best way is to use vinegar essence, put the vinegar essence in a 1:4 solution, do not use too much water, just spread it over the jacquard towel, soak it for 5 minutes, scrub again and then rinse with water. The jacquard towel is an item that people use every day. It has many gaps and is easy to absorb dust and germs. It has close contact with our skin every day. The germs can easily invade people's bodies and make people infected with diseases. The latest scientific experiments have proved that coins, bedding products and jacquard towel products are the three major indirect vectors of disease transmission. Improper use of customized soft hooded bamboo bath towel can damage the skin and, in severe cases, can cause cross-infection. Now most people know the importance of personal jacquard towels, but they are often used for multiple purposes, and they are not broken or changed, and they do not pay attention to the maintenance of jacquard towels. The following is an introduction to the correct use and maintenance of some jacquard towels. 1. Microwave disinfection method, clean the jacquard towel, fold it and put it in the microwave oven, and run it for 5 minutes to achieve the purpose of disinfection. 2. Steam sterilization method, put the jacquard towel into a pressure cooker and heat it for about 30 minutes to kill most microorganisms. 3. Disinfectant disinfection method, the disinfectant can be 200 times diluted cleaning and disinfectant or 0.1% chlorhexidine. Soak the jacquard towel in the above solution for more than 15 minutes, then take out the towel and rinse it with clean water to remove the residual disinfectant. After drying, you can use it again with confidence.

When the galvanized steel sheet is exposed to the air, it is critical to produce dry erosion, wet cold erosion and wet erosion. The dry corrosion of China PPGI corrugated roofing sheet manufacturer means that the surface layer of the steel in ambient air with an air humidity of less than 30% does not produce a continuous corrosion of the electrolyte water film. Under such circumstances, the corrosion rate of steel is relatively slow. But such natural environment standards are too few. The wet cold etching of galvanized steel sheet refers to the corrosion of steel in ambient air with an air humidity of more than 30% and less than 100%. Under such circumstances, there is dust on the surface of the steel, and there are micropores and gaps in the rust layer, which causes the microscope to absorb, produce shrinkage water that is invisible to the human eye, and generate the principle of a galvanic cell under the shrinkage water. The erosion rate is relatively rapid. . Wet erosion of galvanized steel sheet refers to the erosion of China PPGI corrugated roofing sheet factory in the cold and cold ambient air with an air humidity of more than 100%, when the surface has solidified shrinkage water visible to the human eye. Under such circumstances, the shrinkage water of the steel surface layer is too thick, so that the rate of diffusion of oxygen out of the steel surface layer after the melting of oxygen is relatively slow, which reduces the rate of erosion. In fact, the corrosion of steel is closely related to the shrinkage water in the surface layer between the two. It is because there is water, and the water dissolves co2, so that the iron produces a weak electrolyte and produces a series of weak electrolyte reflections. The co2 in the gas continues to melt in the water, and the reaction continues. Because the key product reflected is bright red, the material after iron air oxidation is generally called "red rust". Red rust is very loose, it is very easy to melt, and it is impossible to maintain the surface of the steel without erosion again, which promotes the erosion of the steel until it is completely eroded. It is a characteristic of steel. Because of this, the steel must be coated with other metal materials or the thickness of the protective layer of metal materials in order to reasonably avoid the corrosion of the steel.
