Rare PVC stabilizer successfully developed, the year can be achieved scientific research and

After a year of trial and error, Baotou Rare Earth Rare hospital successfully developed a new type of PVC stabilizer non-toxic, environmentally friendly, long-term stability and good for . Currently , rare earth PVC stabilizer in the test line is under construction , scientific research and is expected to achieve during the year .

PVC material is polyvinyl chloride , such as PVC pipes , PVC wallpaper . When using PVC material is heated to 200 ° C requires pretreatment , the need to add material to prevent thermal decomposition of PVC stabilizers . At present , the domestic PVC stabilizer to lead salt stabilizer most widely used , but there are security issues harm the environment , as the country 's ban of lead , lead -based stabilizers will gradually withdraw from the market . Therefore , PVC materials production enterprises urgently need a stable effect and environmentally efficient and affordable alternative.

Rare hospital engineer Zhang Yuxi told reporters , accounting for 3.5% PVC stabilizer weight , and now our nation's annual PVC production is 13 million tons , and production is still rising , demand is also increasing year by year stabilizers , especially our stabilizer implementation of a comprehensive ban on the use of lead is imminent , the successful development of rare earth stabilizer , PVC producers can meet the demand for environmentally efficient stabilizers great extent. The main component of the rare earth lanthanum cerium stabilizer element content of about 10% , the annual output of 13 million tons terms of PVC per year to use 40,000 tons of elements lanthanum , cerium , lanthanum surplus for digestion Baiyunebo Ce important. It is understood that , at present , rare earth rare earth stabilizer hospital pilot project has been completed equipment tender , is expected to more than three months after the construction , installation , commissioning and operational, is expected to achieve scientific research and then went into effect.
