How to choose the PVC garden tube to your liking?

Generally, although PVC garden pipes are also made of PVC materials, also called PVC pipes, and there are braided layers in them, there are obvious differences in service life, appearance, smell, compressive strength, tensile strength and working pressure. First of all, it is the smell of PVC garden pipes. If you do not see anything, smell it first. This smell is emitted by the polybrominated diphenyl ether contained in the inferior PVC made of PVC materials. The harm of polybrominated diphenyl ether to human beings and the natural environment is becoming increasingly serious. Its smell is very persistent and fat-soluble, causing harm to human liver and nervous system, interfering with thyroid endocrine, and easily causing cancer. At present, many countries such as the United States and Europe have issued documents in 2003 and 2004, which prohibit the manufacture of such pipes. The manufacture of pipes must conform to ROHS and REACH standards before they can be used. Secondly, the PVC garden pipe has poor compressive effect, poor bonding strength, easy hardening in cold weather, and easy folding when held like a wooden stick; Although some PVC garden pipes feel quite soft in winter, cold-resistant plasticizer is added in the production of pipes. The plasticizer is phthalate, which is a chronic poison to human body, easily causing the decline of liver and kidney function and the decrease of red blood cells in blood. It is mutagenic and carcinogenic.
