Although the PVC garden water hose is generally cheap PVC processing, also called PVC hose, there are woven layers inside, but the service life, appearance, smell, compression, tensile strength, working pressure, etc. are significantly different.
The first is the PVC garden hose odor, which has not been seen before. It smells first. This odor is emitted from the PBDE contained in the poor quality polyvinyl chloride used to make PVC. PBDE to humans And the harm to the natural environment is becoming increasingly serious. Its odor is very persistent and very strong in fat-soluble. It causes damage to the human liver and nervous system. It also interferes with thyroid endocrine secretion and can easily cause cancer. Now in the United States and Europe and other countries have issued documents in 2003 and 2004, prohibiting the manufacture of such tubes, tube manufacturing must comply with ROHS and REACH standards before they can use.
The poor quality PVC garden hose has poor compressive strength, poor bonding strength, and easy cold weather. It is as easy to fold as a wooden stick; some PVC
Although the garden hose feels very soft in winter, it is a PVC garden hose with a cold-resistant plasticizer. The plasticizer is a phthalate ester and it is a chronic poison to the human body. It can easily cause a decline in liver and kidney function and a decrease in red blood cells in the blood. Mutagenicity and carcinogenicity.
The third PVC gardne hose woven layer is a poor quality polyester material, the inner layer, the outer layer and the middle woven layer are not firmly bonded, it is easy to peel, which will affect the working pressure and service life.
