Anchorage at high and low parts is the key hub, and construction shall be carried out in strict accordance with the construction drawings and after supervision and inspection. During the construction operation process, the construction combination plan is prepared before the polypropylene nonwoven geotextile factory price is laid out, and the laying method and technical countermeasures are clarified. The quotation of the anti-seepage geotextile is approved by the supervisor before the application. In order to prevent the geotextile from being stepped on, the geotextile should be laid with the pressure, and the geotextile should be laid in harmony with the protection layer. The quality of the geotextile welding seam in splicing is the key to splicing. It is necessary to consolidate the seam inspection during construction. The inspection method has a visual inspection method and two on-site leak detection. Visual method: After the wholesale polypropylene nonwoven geotextile is welded, check whether there is any missing joint, whether the seam is scalded, whether there is wrinkle, and whether it is evenly stitched. Precautions when laying geotextile On-site leak detection uses an inflation method to inspect all welds. The welds are double strips, with a cavity of about 10mm between the two. Seal both ends of the section to be tested, puncture the intake needle, and inflate to 0.05mpa ~ 0.20mpa, stand still for 0.5min, check the vacuum gauge, if the air pressure does not drop, the expression is not leaking, the welding seam passes, otherwise it is necessary to find the elements and quickly repair. The key point of quality inspection after construction is sampling. HDPE polyester nonwoven geotextile for sale construction takes a test piece every 1000m2 for tensile strength test. It is required that the strength is not less than 80% of the base material, and the sample fracture should not be at the joint, otherwise the joint The quality of the seam failed. A total of weld seam samples were taken on site for tensile strength test. After inspection, the pass rate was 100%, and the weld quality was passed. Nowadays, many people will bury the material polyester nonwoven geotextile factory price deep underground. In fact, if people bury other plastic films underground, they may not achieve the desired effect. This is because this material is different from other materials. It has many characteristics and advantages. First of all, this material has corrosion resistance. No matter it is acidic soil or alkaline soil, it cannot form a certain erosion effect on this material. Secondly, it also has low temperature resistance. Therefore, it can be used in a low temperature environment, which proves that its antifreeze properties are very good.

Perhaps it has not been heard by many people. It is extremely common on the construction site. The role of plastic geocells factory price is mainly to isolate the different construction materials. Because there are often a lot of construction materials mixed on the construction site. The situation causes such a situation that the construction materials are not available, so it is at a very poor level to avoid the occurrence of such situations. Geotextiles may wish to avoid the situation where the two types of construction materials are mixed. Geotextile has its solid strengths: it can resist normal salt, acid and alkali use. It can have a good durability in the soil or under the ground, it can have better durability; the friction between the interface with the local soil body is strong, and the interface friction The shielding is poor; the permeable soil decomposes the material and has drainage use, extending the drainage solidification time, and directly catching up with the shear strength of the soil. Because the low price HDPE geocell is used as a reinforced material, it has replaced the natural plants and nonmetals one-sidedly Wage breakdown material reinforced soil Due to the volatility of the mall, the price of the filament geotextile was necessary to influence. During the crucial period, the characteristics of the product are still good, and the natural price will go up! First, the geotextile related geotextile acts as a permanent and independent soil water that obstructs and filters the data and ultimately prevents the accumulation of water pressure, and then prevents the water activity from forming corrosion. The filament wholesale HDPE geocell strains with time under the effect of stable external force The continuous and added scene is called creep when it is used in the project of infiltration, drainage and barrier effect. The filament geotextile is subjected to a steady tensile external force step by step, so the pupa change characteristic of the filament geotextile is the goal of fabric selection; Secondly, geotextile is also effectively used to optimize crop productivity. In short, the storage of geotextile directly affects the effect of high quality plastic geocells. Geotextile manufacturers store their products, must be stored in the above points, in order to ensure the effect of geotextile.

Anchorage at high and low parts is the key hub, and construction shall be carried out in strict accordance with the construction drawings and after supervision and inspection. During the construction operation process, the construction combination plan is prepared before the polypropylene nonwoven geotextile factory price is laid out, and the laying method and technical countermeasures are clarified. The quotation of the anti-seepage geotextile is approved by the supervisor before the application. In order to prevent the geotextile from being stepped on, the geotextile should be laid with the pressure, and the geotextile should be laid in harmony with the protection layer. The quality of the geotextile welding seam in splicing is the key to splicing. It is necessary to consolidate the seam inspection during construction.

The key point of quality inspection after construction is sampling. HDPE polyester nonwoven geotextile for sale construction takes a test piece every 1000m2 for tensile strength test. It is required that the strength is not less than 80% of the base material, and the sample fracture should not be at the joint. The quality of the seam failed. A total of weld seam samples were taken on site for tensile strength test. After inspection, the pass rate was 100%, and the weld quality was passed. The geotextile must be calculated in detail before construction, and many novice technicians are not very clear about this calculation. Why should the geotextile be calculated in detail before construction? It depends on the design contract and construction quotation method. Generally calculated according to area. Pay attention to whether there is a slope or not, multiply by the slope factor. If the lap of the filament nonwoven geotextile for sale is qualified, if the design specifications are not met, the engineering volume shall be reduced accordingly, and rework shall be carried out if necessary. The sum of local structures. Such as parapet, gutter, anti-height treatment and edge treatment, etc., according to your personal relationship and project quality, you can appropriately give twice the measurement area, because the anti-package part itself is made of two layers. Geotextile according to the design specification, look at the local contact depends on the treatment of the rivet, calculate the contact according to the number of contacts. This ensures the accuracy of the geotextile.

Temperature is a key factor in sensitizing aging and toughness. The use of humidity to break branched polymers is explained in two ways: First, it is directly destroyed in view of temperature changes. Due to the tropical zone, fabric fibers can melt, and temperature changes cause changes in the branch structure of the polymer and change the fabric function. Secondly, in view of temperature changes, the deterioration process caused by cables in other countries can be accelerated. Filament aging cloth has many aging elements, and there are many external elements, such as the outer layer of high quality gravel geocell, and the premise of using filament. The use of parts and steps should be relevant to the overall situation and should be analyzed. The practical application of silk-like silk cloth is mainly aimed at the use of geotextile [process implementation], field sampling test, familiar with the aging degree of the fabric during use. In addition, the samples can be placed at the same time during the construction process, and a sampling test should be conducted at the segmentation stage of the engineering operation process to understand the aging degree of the fabric. How to remove stains on geotextile? The manufacturer did not pay attention to the production or preservation of geotextiles, resulting in some stains on the geotextiles. If the stain of the geotextile is not removed in time, it may affect the use of the wholesale plastic geocells. Therefore, when there are stains on the geotextile, we must take measures to remove them. The manufacturer produces a new material geosynthetics. When the stain is too heavy, use a neutral lotion or toothpaste to improve the brightness and brightness after cleaning the surface. When the surface of the dirt cleaning cloth is soiled, a special cleaner for the furniture is wiped off after the manufacturer removes the stain. In order to improve the smoothness of the geotextile, you can wipe it with a soft cotton cloth after cleaning the surface, and it is easy to scratch the surface with the hard part. Be careful not to immerse the neutralizer or cloth on the surface of the plastic geocells factory price, otherwise it will be immersed on the surface. According to engineering needs and specific construction requirements, detailed test reports will be issued. The tensile properties under different negative temperature environments are indeed affected by the water content, and the rate of reduction of the manufacturer's elongation is gradually weakened by the negative temperature. Within the coefficient range, make full use of the tensile properties of short-fiber needle-punched geotextiles. These are all ways to quickly remove stains from geotextiles. I hope you don't think you can leave stains on the geotextile.

The anti-seepage membrane has excellent anti-aging, anti-ultraviolet and anti-decomposition ability, and can be used. The service life of the material is 50-70 years, which provides a good material guarantee for environmental anti-seepage. What are the common construction requirements for impermeable membranes? When the temperature is below 5 ° C, it should not be used according to specifications textured geomembrane factory price. If construction is required, the welder should preheat before welding. In addition to protective measures, welding is not allowed in rainy weather or when there is moisture, dew, or heavy sand at the joints. When welding, it should be powered by a generator with good regulation performance. When using local power under special circumstances, a regulator must be used. During the welding process, the slider of the spray gun head should be checked frequently during the welding process. When the wear is serious, the slider should be replaced in time to avoid damage to the membrane surface. The impermeable membrane has an impermeable effect unmatched by ordinary waterproof materials. The impermeable membrane has high tensile and mechanical strength, and its excellent elasticity and deformability make it very suitable for expanding or contracting the base surface, and can effectively overcome the base surface. Uneven settlement and high water vapor permeability coefficient. What is the quality inspection and control method in the construction of anti-seepage LDPE geomembrane factory price? Earthwork: The quality of the base surface should meet the design requirements. The dry moisture content should be 15%. The base should be dense and even. The basic dry density of the soil should not be less than 1.4t / m2. Flat, no cracks, no obvious spikes, no mud, no depressions, no roots, rubble, stones, steel bars, 25mm vertical glass fragments. The flatness should change slightly within the allowable range, the slope is uniform and the slope is consistent. Material: The geomembrane material used must be qualified, with the corresponding certificate and test report. Laying aspect: When laying smooth geomembrane, the welding seam should be minimized. On the premise of ensuring quality, save raw materials as much as possible, and easily ensure quality environmental geomembrane manufacturers. The overlap width of the joint between the film and the film is usually not less than 10 cm, and the welding orientation direction is generally parallel to the maximum slope, that is, arranged along the oblique direction. When laying, artificial folds should be avoided. When the temperature is low, it should be tightened and leveled as much as possible. The climatic aspect of the construction: the temperature should normally be higher than 5 ° C. The geomembrane should be tight at low temperature, and the geomembrane should be relaxed at high temperature. The wind should be at the fourth level. If there is strong wind, the HDPE geomembrane to be welded should be pressed with sandbags. Welding: The geomembrane should be powered by the generator and have good adjustment performance during welding. In special cases, when using local power, a voltage regulator must be used. In addition to protective measures environmental geomembrane factory price, welding is not allowed in rainy weather or when there is moisture, dew, or heavy sand at the joints. When the temperature is below 5 ° C, it should not be used according to specifications. If construction is required, the welder should preheat before welding.

The storage method of filament geotextile is as important as the method of use. I hope everyone will not ignore it. Only storing the fine-textile 3D geonet factory price in the correct way can ensure that its performance is not affected and there are no problems in use. So how should we store the filament geotextile correctly? The filament geotextile should be protected from damage before installation. The filament geotextile should be stacked in a place where there is no water accumulation, the height of the pile should not exceed four rolls, and the identification piece of the roll can be seen. The filament geotextile must be covered with an opaque material to prevent UV aging. During the storage process, the integrity of the label and the integrity of the data should be maintained. Protect filament geotextiles from damage during transportation (including from material storage to on-site transportation). The physically damaged filament is repaired. Do not use severely worn filament geotextiles. Any filament high quality plastic geonet in contact with leaking chemical reagents is not allowed to be used in the project. When applying filament geotextiles, use the buried type as much as possible, and the thickness of the cover layer or other materials should not be less than 30-40 cm, as thick as possible, so as to be able to exert the corresponding effect. In addition, it cannot be used alone in anti-seepage water systems. Should be used in combination with impermeable layer, protective layer and other products to achieve better results. If it is impossible to achieve the intended purpose alone, then the product itself is. This is something everyone needs to pay attention to in advance and cooperate with other system materials as much as possible. Secondly, the filament geotextile needs to select some construction sites where the soil is relatively strong, as even as possible when laying. Otherwise, it is easy to appear or break in a certain part, which greatly reduces the practicality of the product. And, when in contact with other films, it should be used as a protective layer. Then, during the concrete laying process, the filament HDPE geonet manufacturers will not be too tight. Suitable to relax a bit. It is more suitable for a little ripple. Otherwise, due to the relatively large thickness of the soil layer above, it is easily torn. Once the degree of occurrence is not good, it will be damaged, so it is said that the paving is as loose as possible, which can give the filament geotextile a certain degree of flexibility. When using the product, do not let the stone be pressed on it, otherwise it will easily damage the filament geotextile. Thereby reducing the effect of geotextiles. These are the methods to properly store filament geotextiles, as well as some considerations when using filament geotextiles. I hope everyone will pay attention to them when using and storing.

It is now widely used, leading to fierce competition in the geotextile market. Facing such a fierce market environment, how can we better choose wholesale polyester nonwoven geotextile as a consumer? Can we judge good or bad quality according to the price of geotextile? The following is a detailed introduction to the methods and methods of purchasing high-quality geotextiles. I hope to help you: 1. Look at it. Knitted polyester fabric has many appearances, and serious defects will affect the wearing effect. Such as lack of pinholes, lack of thread, hooked thread, thread breakage, thread tension and severe weft. Shorter defects such as chromatic aberration, curling, poor edges, splicing, knots, knots, color, reflection, oily silk, thick silk, etc. Although you can wear slightly flawed fabrics, it will affect the fabric's grade. 2. Look at the appearance. The appearance of the fabric is closely related to the fabric structure. Therefore, when choosing knitwear, the gloss, color and pattern of the fabric must be carefully observed. When pulling the fabric with both hands polyester nonwoven geotextile for sale, pay attention to the elasticity and extensibility in the longitudinal or transverse direction, whether it is easy to replace; whether the tissue is basic or variable. The gap between the tissue and the coil is loose or tight, and the feel is soft or rough. In short, it is necessary to observe whether the fabric meets the basic requirements of the clothing style and achieve a consistent effect. Appearance of fabric appearance and clothing style. 3. Take a look at the level. Knitted polyester fabric is divided into first-class products, second-class products, third-class products and other foreign products according to quality. From the perspective of the fabric, the quality of the knitted polyester fabric for the product is naturally superior to other grades. In short, when choosing geotextiles, the fewer defects in the fabric, the better! Never judge the quality of a product based on its price, because it is out of context.

The quality of the geomembrane varies, so do not blindly choose the environmental geomembrane manufacturers. There are many different products, different companies, and different qualities in the current market, and when we choose geomembrane, we must also know that the quality of the products varies. Only by understanding these aspects and focusing on some details of the quality of the entire product can we bring more guarantees. Therefore, we hope that we will be able to actively know these in the selection process, and to know more about the geomembrane in a targeted manner. We trust that many of the next things will be as you wish. When selecting environmental geomembrane factory price, do n’t look for the geomembrane price bumps too blindly, whether the targeted detailed product quality is proportional to the price, and do n’t blindly trust any company. In terms of real, to learn more, these are very important to us. Only in this way can we bring more guarantees and be able to make some correct choices.
