The advantages of cotton: hygroscopicity The main advantage of cotton fabric is that the cotton fiber contained in it has good hygroscopicity wholesale sports custom comfortable microfiber beach towel. In general, it can absorb moisture into the surrounding atmosphere, and its moisture content is 8-10%, which guarantees our cotton. The product can make people feel soft and comfortable when contacting the skin, without the dry stiffness. Advantages of cotton: heat resistance The study found that our daily cotton products have good heat resistance. Even at a temperature of 100 degrees Celsius, cotton products will only evaporate water, but it has no major impact on the cotton fiber itself. . Therefore, it also indirectly indicates that our cotton products can be washed, dyed, etc. at will, and will not have a great impact. The advantages of cotton: alkali resistance Alkali resistance can be said to be a relatively large feature of cotton fabrics factory direct sale printed microfiber soft beach towel. Due to the greater resistance of cotton fibers to alkalis, the fibers will not be damaged in alkaline solutions, and it is also because cotton fabrics With such performance, to a large extent, it is convenient for washing and disinfecting items, and it is also conducive to dyeing, printing and various processing of pure cotton textiles, which is obviously that cotton products occupy a more dominant position. Advantage. The advantages of cotton: hygiene All raw materials for cotton products come from naturally grown cotton, and the cotton fiber in cotton is natural fiber, and its main component is cellulose. Cotton products are composed of these cotton fibers. After a comprehensive inspection and practice, the pure cotton fabrics show that the contact between the cotton fabrics and the skin is better, and it is more suitable for everyone to use. With good fabrics and advanced technology to produce excellent products, the cotton era of digital printing products has also quietly arrived.

Cotton is a soft, tough, gentle and powerful product. Now everyone should have heard of the words "whole cotton" and "pure cotton". It is not an exaggeration to say that except for those in the industry wholesale 100% cotton custom digital printing towel, it is estimated that basically everyone will think that the "cotton" and "pure cotton" represent the same cotton content. . In fact, there are some differences between the two. The difference between cotton and pure cotton Cotton: It refers to clothing or supplies with 100% cotton content, generally plain cloth cotton velour reactive digital printing beach towel, poplin, twill, labor cloth, etc. Unlike ordinary cloth, it has the advantages of deodorant, breathability, comfort and so on. Pure cotton: Textiles made of cotton as the textile raw material and interwoven horizontally with warp and weft yarns. Cotton with more than 75% cotton is pure cotton. So pure cotton is pure cotton, and pure cotton is pure cotton. The biggest difference is actually the cotton content. The cotton content of the cotton fabric we use exceeds 95%, which makes people feel the best comfort.

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.

Waterproof geotextiles are used in a wide range of applications, both in construction projects and in daily life. The usage rate is very high. This is because waterproof geotextiles have a good effect and are relatively cost-effective. Now the price of waterproof wholesale filament nonwoven geotextile is receiving much attention, so what are the factors that affect the price of waterproof geotextiles? Let's take a look today. The factors that affect the price of waterproof geotextiles are summarized in three main aspects. The first is the cost of raw materials: the polyester chips used to make geotextiles are extracted from petroleum, and the price of petroleum is not only affected by the domestic situation, but also internationally. Impact of the situation. Then it is the cost of production and processing: In the process of producing polyester nonwoven geotextile for sale by geotextile manufacturers, labor, hydropower, normal loss of products and tax costs must be accounted for. This part also greatly affects the price of waterproof geotextile products. . The last is the cost of transportation: the transportation of waterproof geotextiles requires vehicles and manpower, which is also an important factor affecting the price of geotextiles.

We know that composite geomembrane is a crucial anti-seepage material required in water conservancy construction projects. In modern engineering projects, composite wholesale aquaculture geomembrane may be a common construction material. within the actual laying process, it's often administered in accordance with eight operating steps. First, the primary step is preparation before construction. The underground pipeline networks like cables, optical cables, and plumbing pipelines at the development site are investigated and guarded. Second, the fabric should be checked before laying the composite geomembrane. Third, when cutting a composite geomembrane, the relevant dimensions should be accurately measured, then cut consistent with actual needs. Generally, it's not appropriate to chop consistently with the illustrated size. Fourth, minimize the number of welds when laying an impervious composite low price aquaculture geomembrane, and save raw materials the maximum amount as possible while ensuring quality. it's also easy to ensure quality. Fifth, the overlap width of the seam between each material when laying is usually not but 10cm, and typically the welding seam arrangement direction is parallel to the utmost slope, that is, arranged along the slope direction. Sixth, usually within the corners and deformed sections, the joint length should be as short as possible. apart from special requirements, as long as there's no welding seam on slopes with a slope greater than 1: 6 within 1.5 meters from the highest slope or stress concentration area. Seventh, during the laying process of the composite geomembrane, human damage should be avoided to the best extent possible. When the temperature is low, it should be tightened and laid as far as possible. Eighth, finally, after the laying of the composite geomembrane is completed, walking on the membrane surface, moving tools, etc. should be minimized, as long because it is probably going to cause damage to the fabric, it shouldn't be placed on the fabric.
