PVC three-proof tarpaulin is often used in our daily life. When the PVC three-proof tarpaulin does not need to be folded, the front of the tarpaulin is spread out flat, leaving two side ropes, and the two sides of the length direction are folded. Fold the edges toward the longitudinal centerline of the tarpaulin. Divide the folded sides into thirds and fold them twice towards the center line. Fold both sides of the tarpaulin in the width direction to the horizontal center line of the tarpaulin, and then fold them in half three times in a row to the middle, and then jump firmly. Bundle with reserved rope, tie crosses on both sides, tighten and tie tightly, and plug the rope end well. The key component of PVC three-proof tarpaulin is polyethylene. In the production and processing of PVC three-proof tarpaulin, many auxiliary materials such as plasticizers and anti-aging agents are added to improve its performance, and the surface layer is viscous epoxy resin and so on. It is a kind of additive with weather resistance and good reliability. The PVC three-proof tarpaulin should be covered with a layer of suture glue in the place of the waterproof suture glue to ensure its good waterproof effect. During the use of the tarpaulin, it should avoid collision with sharp metal. If there is local damage, it can be repaired with glue. The service life of the tarpaulin is limited. If it is used for a long time, the surface of the tarpaulin will be aged, and the phenomenon of water seepage will occur. When necessary, a new tarpaulin should be purchased so as not to affect the quality of the goods. After the PVC three-proof tarpaulin is used, you can properly clean the swag on the waterproof tarpaulin. When storing, you should choose a cooler indoor place, be careful not to be pressed by heavy objects, and can be placed in the corner of the warehouse. When using tarpaulin to cover the goods, it is also necessary to pay attention to the fact that the reserved air vents will be too sealed, which will cause water vapor to damage the goods, and try to use corrosive items as much as possible. What needs to be done to save the PVC three-proof tarpaulin? 1. If you want to install it, you need to read the manual of the tarpaulin carefully, and see the installation position and installation position clearly, and do some details of the installation of the tarpaulin. 2. The mildew of the waterproof tarpaulin will destroy the waterproofness of the tent. In case of mildew, use a sponge with a little detergent to gently brush off the mildew, and then dry it in the sun. 3. After the waterproof tarpaulin has been placed for a period of time, it should be taken out for exposure to prevent bacteria from appearing. After the outdoor trip, remember to hang the tent to air dry. If the automatic tarpaulin is a little dirty, wash it gently with cold water. That's it! 4. When storing the tarpaulin, don't get close to the sharp things, so as not to be scratched and affect the use. 5. After using up the waterproof tarpaulin, all the parts should be sorted out accordingly, so as not to struggle to find it later, and form a good habit. 6. Do not use chemical lotions or scrub hard, which will destroy the waterproof membrane on the surface of the fabric and reduce the waterproof effect of the tarpaulin. It can be seen from the above that PVC three-proof tarpaulin is now widely used in various industries. The tarpaulin needs to be maintained after use. Moisture, frost-proof tarp. It is made of fiber materials and organic chemical filling raw materials, and is made through the production and manufacturing process. The standard raw material composition of the tarpaulin is a fabric woven by hand with tensile strength polyester fabric, which is appropriately matched with other small amounts of chemical raw materials to produce and process. PVC three-proof tarpaulin has excellent physical and chemical properties such as high strength, good waterproof performance, good self-cleaning, corrosion resistance, flame retardant, long service life, etc., which improves the surface characteristics of traditional coating materials. It has excellent anti-pollution ability, maintains long-term cleanliness and excellent weathering resistance, prolongs the service life and enhances the resistance to chemical corrosion. Considering the various uses of the tarpaulin, the general requirements should be: light weight, easy to fold, easy to handle and operate; high strength, wear resistance, long service life; good waterproof performance and air permeability, anti-condensation on the inside; Acid and alkali, anti-mold, anti-corrosion; good weather resistance, flame retardant, fire prevention; no wicking effect, no moisture conduction phenomenon. It has UV resistance, performance, flame retardancy, fire resistance, excellent tensile, tear resistance, peel resistance, good abrasion resistance, can be used repeatedly, and saves costs. Tarpaulins are generally required to have“Three defenses”Function. That is, waterproof, fireproof (flame retardant), and mold prevention. The air permeability of tarpaulins is considered, especially for military tent fabrics. The factors affecting air permeability include base fabric organization, density, material, type of waterproof finishing agent, and resin adhesion. With the increase of resin adhesion, the air permeability of the tarpaulin decreased. Of course this depends on the finishing agent used. Generally, most of the tents with air permeability are made of cotton, vinylon, lacquer and other short fiber fabrics finished with paraffin or acrylic resin.
Whether it's automation or artificial intelligence, the rapid convergence of technology and business often determines PVC Film’s competitiveness.
