Inferior PVC hoses are significantly different from our company in producing quality products in terms of service life, appearance, odor, compression resistance, tensile strength, and working pressure. Let’s talk about the hazards of poor quality PVC hoses and how to distinguish them.
The first is the smell, the smell is not seen, and the smell is first emitted from the polybrominated diphenyl ether contained in the inferior polyvinyl chloride fabric for the manufacture of PVC. PBDE for humans and the natural environment. The harm is getting more and more serious. Its odor has strong persistence and strong fat solubility, which is harmful to human liver and nervous system, and interferes with thyroid endocrine, which is easy to cause cancer. Now many countries such as the United States and Europe have issued documents to prohibit the manufacture of such pipes. Pipe manufacturing must comply with ROHS and REACH standards before they can be used.
The second pressure resistance is poor, the bonding strength is poor, the cold is easy to be hard, and the hand is like a wooden stick, which is easy to fold; although some pipes feel very soft in winter, the tube is produced with a cold-resistant plasticizer, plasticized. The agent is a phthalate ester, which is a chronic poison to the human body. It is easy to cause a decrease in liver and kidney function, a decrease in red blood cells in the blood, and is mutagenic and carcinogenic.
The three woven layers are made of inferior polyester material, and the inner layer, the outer layer and the intermediate woven layer are not firmly bonded, and are easily peeled off, thus affecting the working pressure and the service life.Learn more about identify the properties of PVC hoses
