Briefly describe the specific functions and preservation skills of three-proof PVC tarpaulin

Speaking of three-proof PVC tarpaulin, we can't help but ask which three-proof is it, in fact, this three-proof PVC tarpaulin has the characteristics of fireproof, waterproof, and so on. The three-proof PVC tarpaulin is made of special fiber technology, and its effect is powerful. It can play a protective role in harsh conditions such as humidity, smoke, and chemical gases. At the same time, it is also used in fire clothing, fire blankets, fire bags, electric welding, fire curtains and other products. This PVC tarpaulin has its own characteristics, high temperature resistance, good sealing, no irritation, good corrosion resistance, no burning, high toughness, and can be used on objects of any shape. It can protect the integrity of items, isolate the fire source, and prevent burning. For this reason, it is mainly used for fireproof covering PVC tarpaulin, which prolongs the burning and explosion time, increases the rescue time, and has a protective effect on personal and property. The PVC three-proof tarpaulin is anti-ultraviolet, and the outdoor shelf life is long regardless of the cause of ink fading. High strength, good weather resistance, can be used in the environment of minus 30 ℃ to minus 80 ℃. The coated inkjet cloth has a smooth surface, and the output image has high saturation and precision. With high-quality ink, the effect can be close to the printing quality. Suitable for indoor and outdoor wide-format digital inkjet, eco-solvent inkjet and screen printing. Due to the durable characteristics of PVC three-proof tarpaulin, it is widely used in various industries. In fact, after the tarpaulin is used, keep it well, and you can continue to use it next time, so how to save the PVC three-proof tarpaulin? The following points are summarized: 1. Then, evenly divide the folded two sides into three parts, and fold them twice in a row toward the longitudinal center line. 2. Fold both sides of the PVC three-proof tarpaulin in the width direction to the horizontal center line of the tarpaulin, and then fold them in half to the middle continuously (three times for the D type), and then press down firmly. 3. Bundle it with a reserved rope, tie the cross on both sides, and tighten it tightly. At the same time, the rope head is fortified, so that there is no looseness and rope buckles falling off, and the bundled PVC three-proof tarpaulin must not be dragged. After that, it is necessary to pay attention to the storage location of the PVC three-proof tarpaulin. The reasonable storage place of the PVC three-proof tarpaulin is indoors. Do not expose it to the outdoors. In addition, keep the space for circulation and keep it away from heat sources. 4. First, spread the PVC three-proof tarpaulin flat face up, remember to leave two end ropes (D type is angle rope), and then fold the two sides of the length direction to the longitudinal center line of the tarpaulin. 5. It is easy to use when folded, and the road emblem and tarpaulin number on the tarpaulin should be completely and clearly exposed for the next use. In fact, the purpose of folding the tarpaulin is to facilitate the handling, number copying, loading, inventory, stacking and storage of the tarpaulin. PVC tarpaulin generally has rainproof performance. In people's eyes, how many mm of water column per square centimeter is used to calculate its rainproof performance. Such as tents will reach 3000-4000mm, so that their rain protection level will rise, reaching the resistance of continuous rainstorms. The rainproof tents of general tents are above 1500mm water column, which can only prevent moderate to heavy rain. Although the rainproof index of the tent is relatively high, its ventilation is also an important issue. Because if it is not breathable, it will also affect the quality of the products in our tent. Only when both goals are achieved can the quality of the products be guaranteed. What is the working principle of the waterproof PVC tarpaulin? From our theoretical point of view, the waterproofness of the fabric and the breathability of the fabric are a pair of contradictions. If a fabric has good waterproof performance, its air permeability is poor; on the contrary, if a fabric has good air permeability, its waterproof performance is poor. Solving this contradiction is the key to developing PVC waterproof and breathable PVC tarpaulin. We all know that the small diameter of water molecules is 100 microns, but the large diameter of steam is only 0.0004 microns. The difference between the two diameters is huge, reaching nearly 250,000 times. Some people say that waterproof and breathable are contradictory, but it can be solved. We can make the waterproof coating of the fabric into a porous shape. If the pore size is too small, the waterproof performance is good, but the breathable performance is poor, and vice versa. different effects.
