Pvc tarpaulin is characterized by high durability and solidity, waterproof, mildew-proof, cold-resistant, aging-resistant, and anti-static, and can provide a high level of weather protection. The appearance of pvc tarpaulin is bright and colorful, the surface has been specially treated, and it has an anti-skid function. It is an internationally popular tarpaulin.
Here is the content list:
l Features and precautions of PVC tarpaulin
l PE tarpaulin and pvc tarpaulin
1. It has waterproof and mildew-proof functions, and has the characteristics of light material, high tensile strength, acid and alkali resistance, high-temperature resistance, and convenient washing and folding;
2. During use, PVC tarpaulin should avoid colliding with the sharp metal fast mouth;
3. If the PVC tarpaulin is damaged during use, it can be repaired with glue
1. PE tarpaulin
PE tarpaulin is a double-sided PE film with a layer of loosely woven polyethylene plastic strips in the middle. Its production process is rounding-weaving-double film.
Polyethylene (PE) is a semi-crystalline thermoplastic material, divided into high-density polyethylene (HDPE), low-density polyethylene (LDPE), and linear low-density polyethylene (LLDPE).
Among them, HDPE is the raw material for making PE tarpaulin. The appearance is a white powder or granular product, non-toxic and tasteless, and the density is 930-970kg/m3.
Advantage
PE tarpaulin has a good heat resistance and cold resistance, good chemical stability, and is insoluble in any organic solvent at room temperature. It is resistant to most acids and alkalis, has low water absorption, remains flexible at low temperatures, and has high electrical insulation. Moreover, the PE tarpaulin is light, clean, and pollution-free, which is convenient for transportation and storage.
Shortcoming
The disadvantage of PE tarpaulin is that it is easy to wear and tear. Thermal oxidation will degrade its performance, and it is easy to age and become brittle. The surface hardness of PE tarpaulin is low, which is easy to scratch and stress crack. And it is not suitable for long-term use in the open air.
Application
PE tarpaulin has many uses, such as protecting unfinished buildings from wind, rain, or sunlight (reinforced polyethylene cloth); as a temporary covering for building materials; covering temporary fences to protect them from the weather and extend Its lifespan; or it can also be made into tents, cargo covers, garden bags and more.
2. Pvc tarpaulin
Pvc tarpaulin is made of high-strength polyester canvas, coated with polyvinyl chloride (PVC) paste resin, and added with growth agents, anti-fungal agents, anti-aging agents, anti-static agents, and other chemical additives, using impregnation technology, the process is as follows: Long-dip coating, drying and shaping - light pressing and cold rolling.
The raw material polyvinyl chloride is yellowish translucent, shiny, and more transparent than polyethylene.
Advantage
Polyvinyl chloride is a tough, cost-effective material that is hard, mechanically strong, and has good chemical resistance. Moreover, PVC is a natural flame retardant, which has the advantages of flame retardancy (flame retardancy value above 40) and good electrical insulation.
Shortcoming
The light transmittance of pvc tarpaulin is not very good, which reduces the natural light inside the building. And when using PVC tarpaulin, it is best to avoid sharp objects from scratching the tarpaulin, which will reduce its waterproof performance of the tarpaulin.
