What are the different uses of PVC three-proof tarpaulin?

At present, the motor used in the PVC three-proof tarpaulin mechanism of the muck truck on the market is equipped with a corresponding reducer control, and the opening and closing of the PVC three-proof tarpaulin cover is realized on the guide rail through the wire rope Zhai Dong active roller skating and driven pulley. According to the value of the information fed back by after-sales service, the failure rate of the modified structure is high during use. The main faults are that the wire rope is easy to break down, resulting in a short service life, the pulley is easy to be damaged, the rear seal is easy to be damaged due to the accumulation of soil, and the PVC three It takes a long time to open and close the tarpaulin. The practicality of the rear tensioner is not high. The mechanism adopts a new structural form, the power is controlled by the power unit, and the opening and closing of the PVC three-proof tarpaulin is realized through the telescopic action of the small oil cylinder. . The PVC three-proof tarpaulin mechanism is mainly composed of a small oil cylinder, a support tube assembly, a poor support assembly and a PVC three-proof tarpaulin track. The connected poor support frame assembly ensures that the front end of the PVC three-proof tarpaulin is fixed. The problem of falling off the PVC three-proof tarpaulin on the truck has become the focus of the current cargo loading work. The falling off of the train's PVC three-proof tarpaulin can easily cause accidents such as scratching railway equipment and injuring pedestrians. The PVC three-proof tarpaulin falls off on the rails. , and also easily lead to derailment and rollover accidents of railway vehicles. Causes loss of goods. After the PVC three-proof tarpaulin falls off, the goods are easily blown off by strong winds and wet by rain, resulting in loss of goods. The falling off of PVC three-proof tarpaulin also provides an opportunity for cargo thieves. After the railway has been greatly increased in speed, the current PVC three-proof tarpaulin method of the railway train can no longer meet the needs of the speed increase. When the railway PVC three-proof tarpaulin passes through the tunnel group, it is blown in from the lap joint of the PVC three-proof tarpaulin due to its huge sharpness. , It is easy to blow and tear the PVC three-proof tarpaulin, and pull the rope off. Briefly describe the use of PVC three-proof tarpaulin: 1. PVC three-proof tarpaulin for freight transport of automobiles and trains; 2. For covering the stacks of open-air warehouses for vehicles; 3. For building temporary granaries and open-air covering of various crops; 4. Construction site power Temporary sheds are built on various construction sites such as construction sites; 5. Outer sheaths of various machinery and equipment; When designing and using PVC three-proof tarpaulins, the breathability of PVC three-proof tarpaulins needs to be considered, and the influencing factors of breathability are at the bottom Cloth structure, density, material, type of waterproof finishing agent, amount of resin adhesion, etc. Generally, air-permeable tents are mostly products finished with paraffin or acrylonitrile resin. The PVC three-proof tarpaulin has to bear various tensions when it is used. When it is fixed, it must be under tension. During the use process, it must be affected by wind and rain. This requires the PVC three-proof tarpaulin to have good tensile strength. It is required to keep the original star creation, and it will not be easily deformed. As a canopy tent and a large tent, it is often used under tension, and the elongation of the fabric should not be too large, and its dimensional stability is determined by the creep characteristics of the material. There are many kinds of materials used in PVC three-proof tarpaulin, and what people call PVC three-proof tarpaulin is a broad concept, and it is not correspondingly made of cloth. PVC three-proof tarpaulin is a PVC three-proof tarpaulin that is produced and processed to be waterproof or moisture-proof and freeze-proof. 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 PVC three-proof tarpaulin is a cloth blank woven by hand with tensile strength polyester cloth, which is appropriately matched with other small amounts of chemical raw materials to produce and process. The key component of PVC PVC tarpaulin is polyethylene. In the production and processing of PVC PVC tarpaulin, many auxiliary materials such as plasticizers and anti-aging agents are added to improve its performance. The surface layer is viscous epoxy resin, etc. It is a kind of additive with weather resistance and good reliability. In addition, as various optoelectronic technologies are more and more widely used in military detection equipment, higher requirements are put forward for the camouflage protection of military weapons equipment and facilities. Therefore, it can no longer meet the needs of modern national defense development. In order to better protect weapons and equipment in storage, transportation and with lights, more and more attention has been paid to the stealth of equipment, and stealth fabrics are cheap and easy to use, which has become an urgent need for the army. The tarpaulin can greatly reduce the weight of the military PVC three-proof tarpaulin, improve the service life of the PVC three-proof tarpaulin, and enhance the rapid response capability of the troops, which is of great significance to high-tech warfare. The new PVC three-proof tarpaulin mainly achieves stealth performance by adding stainless steel fiber. Stainless steel fiber has anisotropy, dielectric loss and magnetic loss, and is a material with better Hi-wave performance.
