What are the requirements for making PVC three-proof tarpaulin?

PVC three-proof tarpaulin has strong tensile strength, no water seepage, no water leakage, low temperature resistance, cold resistance temperature of -20 ℃, can prevent mildew, and can be used as freight tarpaulin for cars and trains; build temporary granaries and open-air cover for various crops It is used for building temporary work sheds on various construction sites such as construction sites, electric power construction sites, etc.; it is used to cover the stacks of open-air warehouses for vehicles; the outer sheath of various machinery and equipment. PVC three-proof tarpaulin coated high-strength polyester waterproof cloth is based on high-strength polyester canvas, coated with polyvinyl chloride (PVC) paste resin and added with accelerator (synthetic vegetable ester), anti-mold agent, anti-mold Aging agent, antistatic agent and other chemical additives are plasticized at high temperature. It has the properties of waterproof, mildew prevention, cold resistance, aging resistance, and static electricity prevention; and its breaking strength, tear elongation and tearing strength are much better than traditional tarpaulins. It has a wide range of use and high intensity of use, and is a mainstream product in the modern tarpaulin market. PVC three-proof tarpaulin is the same as other tarpaulins. When using it, you should avoid sharp objects from scratching the fabric. After use, it should be unfolded and dried before being packaged and stored. .Depending on the local humidity and climate. Regularly drying, try to pay attention to even force during handling. To prevent damage to the outer packaging, prevent brute force from tearing the insulation quilt, and pay attention to fire prevention. What are the requirements for making PVC three-proof tarpaulin? 1. Nowadays, many tarpaulin manufacturers add tarpaulin rings at the corners of the tarpaulin in order to facilitate the use of tarpaulins when producing tarpaulins. However, relevant professionals should pay attention to the design of such tarpaulin rings. It needs to be simple in shape and reasonable in structure. 2. In order to simplify the mold structure and simplify the number of processes, that is, to complete the processing of the entire part with few and simple stamping processes. It reduces the use of other methods for processing, and is conducive to stamping operations, which facilitates the organization of mechanized and automated production to improve labor productivity. 3. Under the condition of ensuring normal use, try to make the dimensional accuracy grade and surface roughness grade requirements lower, which is conducive to the exchange of products, reduces waste, and ensures stable product quality. 4. The designed tarpaulin ring should be beneficial to use the existing equipment, process equipment and process flow as much as possible to process it, and it is beneficial to prolong the service life of the die. 5. Generally, woven plain weave cloth is used, and there is a reinforcing wire every 50mm in the warp direction. Then carry out plastic coating. The plastic coating raw material is generally polyvinyl chloride. The coating of the base cloth should be uniform, and there should be no leakage, agglomeration, holes, degumming, wrinkling and damage, and the front side is the thinner side of the coating. , the reverse side of the tarpaulin is the side with the thicker coating. 6. On the whole, it will have 26 eye circles, 7 waist ropes, 4 corner ropes, 4 end ropes, 2 pressure ropes, 7 reinforcing ribs, and 3 rope cloths are evenly distributed on each reinforcing rib. , There is a wrapping rope around the tarpaulin, and the front ends of the tarpaulin have pressure rope cloth. Introduce the advantages of PVC three-proof canopy from different aspects: 1. Waterproof performance: 1. Waterproof performance, good collagen fibers, white canvas will not have needle holes, and excellent production materials. The addition of materials, the amount of resin composition, and the relative density all determine the performance of pVc tarpaulins. 2. Appearance: good color, bright and back to light; one side is smooth and clean, and the other side has a trace of particles, indicating that the resin composition is moderate and the temperature is suitable; there is no needle hole, the resin has high relative density, and good aging resistance. Use long term. 3. Touch: It feels very soft to the touch. Although it feels thin and thick, in fact, the thickness has met the requirements. It is just because the resin composition is high and the processing skills are good, so the touch feels very soft and does not feel rough. 4. Tensile resistance: According to different processes, the white canvas is finely ground on the material preparation, so that the damage to the blank is small, and the tensile strength will be better; the higher the relative density of the yarn, the higher the tensile strength. powerful. The traditional PVC three-proof tarpaulin used as a covering object is mainly made of chemical fiber woven cloth after compounding a layer of film as the base material. The plastic woven fabric is made by casting and laminating on one or both sides. When the production cost, wages and processing costs of the woven fabric rise rapidly, the use cost of the tarpaulin increases rapidly. This tarpaulin is widely used to cover objects, carports, temporary structures on construction sites, membranes or tents for geotechnical engineering. The single-sided or double-sided laminating woven fabric laminating tarpaulin has a low cost and has a wide range of uses. Production costs, wages, processing costs, etc. rose rapidly. The new tarpaulin has tensile strength in the warp and weft directions, and has tear strength because of bonding together, and also has waterproof and anti-leakage properties. It is a tarpaulin made of a composite membrane.
