Interpretation of tarpaulin detection knowledge
Tunnels (or waterproof cloth) are waterproof materials with high strength, good toughness and softness. They are often used as canvas (oil canvas), polyester with polyurethane coating or polyethylene plastic.
The purpose of the tarpaulin is very wide, which is closely related to people's work and life. How can we buy a functional and reliable canned cloth products? Today, I will take you to understand the national standards and quality requirements of the canopy cloth.
There are many types of tarpaulin, and the materials of each type of canbur cloth are different, and the effect is different. Tobules usually have strong rings on the corner or edge to facilitate the use of ropes to bundle, suspend or cover.
Because of its waterproof characteristics, it is often used in construction sites, chemicals, food rainproof, and waterproof trucks. Because of its shading characteristics, it is often used in the raw materials of the factory and sunscreen in the greenhouse.
There are many national standards for tarpaulin. Quality requirements involve chloride ion detection, quality testing, tensile detection, fire prevention level detection, combustion performance detection, index detection, material detection, aging testing, density detection, service life evaluation, and so on. Taking the packaging industry standard "BB/T0037-2012 Double-sided double-sided coating of polyvinyl chloride flame-retardant waterproof cloth and tarpaulin" as an example, take you to learn more about it.
The first is the conventional requirements of the tarpaulin, including appearance, size deviation, and unit area quality deviation. The appearance is the key, and a good organizational structure is an important prerequisite for high -quality products. Factory inspection generally only detects the appearance, size deviation, and unit area quality deviation. If the formula, production process structure, and material change are changed, type tests including physical mechanical properties are required.
