Rare PVC stabilizer during landing results

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 .

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 , debugging put into operation, is expected to achieve scientific research and then went into effect.

When using PVC material is heated to 200 ℃ require 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 safety hazards environmental issues. To meet the international trend to ban lead on PVC industry , China in recent years have gradually taken a series of measures to limit and reduce the use of lead salt stabilizer , lead stabilizer will gradually withdraw from the market , PVC materials production enterprises urgently need a stabilizing effect good cheap alternative and environmentally efficient products . The successful development of rare earth stabilizer , PVC producers can meet the demand for environmentally efficient stabilizers great extent.

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 overall lead ban is imminent. The main component of the rare earth lanthanum cerium stabilizer element content is 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.
