Briefly describe the waterproof treatment and maintenance methods of PVC three-proof tarpaulin

The PVC three-proof tarpaulin has minor problems such as disconnection, disconnection, or loose decorative parts, which should be repaired in time. to extend its service life. Generally, canvas is divided into two categories, one is coarse canvas and the other is fine canvas. Coarse canvas is also called tarpaulin, tarpaulin. Because the fabric woven from this type of canvas is strong, sturdy, resistant to folding, and has relatively good waterproof performance. It is often used by us for transportation and cover of open warehouses. This is also the origin of the name tarpaulin and tarpaulin. We also use coarse canvas to pitch our tents in the wild. A widespread use of canvas is to use coarse canvas to make camp tents. Fine canvas is generally used by us to make protective clothing for labor. Generally speaking, waterproof and breathable have corresponding opposites: if a fabric has good waterproof function, then its breathable function is poor; on the contrary, if a fabric has good breathable function, then its waterproof function is poor. In some cases, the PVC three-proof tarpaulin does not have the function of waterproofing, and in some cases, it is required to have a waterproof function, so it needs to be waterproofed. 1. Analysis of the waterproof treatment method of PVC three-proof tarpaulin: (1) The treatment method of silicone waterproofing agent is selected: it has good waterproof effect, good hand feeling, long service life, good air permeability, and good climate adaptability, which is now relatively method of handling. (2) Treatment method of resin derivative waterproofing agent: This kind of waterproofing agent is a mixture of fatty acid, fatty alcohol, etherified methyl resin and ceresin (waterproofing agent). Its waterproof effect is good, the service life is average, and the processing technology is more complicated. (3) Adopt aluminum soap waterproof method: This method has waterproof effect, but it is not durable. (4) Chlorosulfonated polyethylene waterproof treatment method. This kind of waterproofing agent has good waterproof effect, long waterproof life and wide adaptability to climate. However, the waterproofing agent is expensive, the tarpaulin is unpleasant, and xylene is generated during the processing, which pollutes the environment. (5) Use quaternary ammonium waterproofing agent treatment method: This method has better waterproof effect. (6) Water repellent Ac treatment method: This kind of water repellent is the stearic acid stearate compound of chromium chloride and aluminum chloride. It has good waterproof effect, long service life, good hand feeling, good air permeability and low processing cost. (7) Paint wax waterproof treatment method: After using this method, it has a good waterproof effect and a long service life, which is one of the many methods currently used. 2. How to maintain the PVC three-proof tarpaulin in daily use? (1) When unfolding, place it in a good place and then unfold it to avoid damage to the insulation caused by pulling on the ground. (2) After use, it should be unfolded and dried, packaged and stored for reuse. (3) Please predict the local wind, and strengthen it in advance when the wind is too strong. (4) During the handling process, attention should be paid to the uniform force as much as possible to prevent the outer packaging from being damaged and the thermal insulation quilt from being torn by brute force. (5) When using, avoid scratching the fabric with sharp objects, resulting in a decrease in the waterproof performance of the fabric. (6) Generally, it is not fireproof. When using it, pay attention to keeping away from the fire source, and pay more attention to fire prevention when stocking it. (7) The ground should be checked before deployment, and sharp objects should be removed to prevent the insulation from being damaged by the surface cloth. (8) When stacking inventory, attention should be paid to preventing moisture and rodent bites. Depending on the local humidity and climate, air it regularly. The PVC three-proof tarpaulin makes the waterproof coating of the fabric with holes, the pore size is 200-500 microns, and a certain substance is implanted in the holes, and the implant absorbs and swells to block the holes when it is waterproof (rain). Prevent water from passing through the hole, shorten the opening of the hole when the water is not released (the weather is fine), and let the air pass through the hole, so that the knife is waterproof and breathable. The waterproof layer of the fabric is made with holes, and the pore size is less than 100 microns, so that only air can pass through the holes, and no water can pass through the holes, so as to achieve the purpose of waterproof and breathable. PVC three-proof tarpaulin is widely used in reality. It is mainly used in simple tents, chicken coops, pig houses, equipment storage yards, construction sites, and agricultural cultivation goods, material storage, transportation, etc. used in sports events. Ports, ships, industrial facilities and daily life, etc. There are many kinds of tarpaulins that can be distinguished from the quality of the tarpaulin. The density of the tarpaulin is also related to the cost of the product and the size of the production efficiency, but the quality of the tarpaulin has an advantage. In terms of service life, or in terms of use time, the use time of the tarpaulin is far more than the use time of nylon.
