What materials are PVC three-proof tarpaulins made of?

The traditional tarpaulin used as a covering object is mainly made of chemical fiber woven cloth as the base material after compounding a layer of film. 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. Due to the development of containers and covered trucks, it is less applicable to touch. Through the selection of base fabric texture, the research of coating formulation and the optimization of process conditions, the contradiction between flame retardancy and cold resistance of tarpaulins has been solved, and the product resistance Aging performance, extended service life, and its main performance exceeds the level of railway standards. The flame retardant of tarpaulin includes vinylon canvas and pvc coating. Due to the high cost of reactive flame retardants and the complicated process, this study uses additive flame retardants to add pvc coatings to make them flame retardant, and pvc itself has resistance. In order to ensure the cold resistance of the tarpaulin, it is necessary to add a plasticizer. This is the production of PVC three-proof tarpaulin. Adding flame retardants to PVC three-proof tarpaulin can improve the flame retardancy, but reduce the cold resistance, so solving the contradiction between the flame retardancy and drought resistance of the product is the key of technology. healthy. If there is a white side, we can also apply some toothpaste on its surface to prevent the tarpaulin from discoloring. In addition, we should also note that the force should be appropriate when cleaning, it should be gentle and even, and it is not possible to use a brush to brush with brute force, which is easy to damage the canvas line and its color. The plastic spraying line is an increasingly common product of the development of industrial technology. With the increasing degree of automation, the application of the plastic spraying production line is becoming more and more extensive. Introduction to the materials used in the PVC three-proof canopy: 1. Textiles, that is, the real cloth. 2. If the shielding area is not wide, it can be made of PVC material or nylon material. 3. The occlusion surface is wider, but the things that are occluded are not too important. Like the PVC three-proof tarpaulin used in rural areas, oilcloth is generally enough. If the color of the PVC three-proof awning is relatively light, avoid cleaning with some items that are difficult to clean when cleaning, to prevent the inconvenience of cleaning after dyeing and destroy the aesthetic effect of the tarpaulin. Therefore, in order to ensure normal and stable use, use When the spraying equipment is finished, the coating system of the spraying equipment should be cleaned in time, and attention should be paid to cleaning it all to prevent the coating from solidifying and blocking the equipment. During operation, start from low pressure, gradually pressurize, observe whether all parts of the pipeline and equipment are normal, and pay attention to the stability lock of the spray gun when the operation is interrupted. Before using the plastic spraying line, the operator should wear labor protection equipment, the work clothes worn by the workers should be anti-static clothing, and the work shoes should also be free of iron nails. The PVC three-proof tarpaulin has the functions of waterproof and mildew resistance, and has the characteristics of light material, high tensile strength, acid and alkali resistance, high temperature resistance, and convenient washing and folding. In the process of use, avoid impact with sharp metal quick mouth. If damaged, it can be repaired with glue. 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), antifungal agent, anti-aging agent A variety of chemical additives such as antistatic agent and antistatic agent are plasticized at high temperature. It has the properties of waterproof, mildew proof, cold resistance, aging resistance, anti-static and so on; and the breaking strength, tear elongation and tearing strength are much better than traditional tarpaulins.
