After using the waterproof tarpaulin, be sure to organize all parts

The waterproof tarpaulin is composed of polymer waterproof and breathable materials and fabric composite fabrics. It is very practical and has a variety of types. It can be used in many fields. Maintenance should be carried out during the use of the waterproof tarpaulin to ensure its normal use.

1. After the waterproof tarpaulin is moldy, the mold on it will destroy the waterproof performance of the tarpaulin. If it is moldy, use a sponge dipped in detergent to gently wipe the moldy and dry it.

2. If the waterproof tarpaulin is installed, first carefully read the instructions of the waterproof tarpaulin. Look at the direction and location of the installation, and do some details of the tarpaulin installation.

3. After using the waterproof tarpaulin, be sure to organize all parts and develop a good habit, so as not to find it later.

The following performance indicators of tarpaulin should be considered in specific product design or use.

1. Breathability: Consider the breathability of tarpaulins, especially military tents. Factors affecting breathability include the structure, density, material, type of water repellent and resin adhesion of the base fabric. The air permeability of the tarpaulin decreases as the resin adhesion amount increases. Of course, this depends on the integrator used. Generally, most breathable tents are made of paraffin or acrylic refined cotton, vinylon, paint and other fabrics.

2. Tensile strength: in the process of use, the tarpaulin needs to bear various tensions, such as tightening it will be tensioned: in the process of use, it will bear additional forces, such as wind, rain, saving despite these external forces, but It is still required to keep its original shape and not easily deformed. This requires the tarpaulin to have a higher tensile strength, and the tensile strength in the warp and weft directions cannot be too different. Especially the tensile strength of the marquee used as an inflatable building is important. In general, the base fabric is made of high-strength polyester, vinylon and other long-fiber fabrics, which are waterproof and finished with vinyl chloride resin and chlorosulfonated polyethylene resin. The strength of the product mainly depends on the strength of the fiber material and the density of the fabric.

3. Elongation and dimensional stability: As eaves tents and large tents, the tension state is often used. The elongation of the fabric should not be too large, and its dimensional stability depends on the creep characteristics of the material.

4. Tear strength: The damage of the awning cloth is mainly caused by tearing, so the tear strength is an important symbol of the awning. Tear strength is related to whether the tarpaulin will rupture due to the action of flying foreign objects or a large structure formed by structural cracks for some reason that expand into the surrounding environment after forming holes. Therefore, when the pulling force is high. Not only high tensile strength, but also high tear strength.

5. Water resistance: Water resistance is an important feature of tarpaulins. After the vinyl chloride grease is impregnated and finished, it is filled in the gaps of the fabric to form a film. If the resin adhesion per unit area exceeds a certain level, the water resistance is not a problem. If the membrane is very thin, the membrane can break easily when it is bent, rubbed, or worn away from the surface, potentially causing muddy water.
