How to reduce the lead and lead metal PVC products in the production and recycling process of environmental and related personnel caused by pollution and harm, is an urgent problem to be solved. China's PVC plastic products and international standards is the trend, in the current economic downturn, so that lead-free, low lead products can also achieve a variety of plastic products, economic indicators, and easy to use, efficient, environmentally friendly and economic, which is At present, many scientific research institutions and enterprises to increase investment, and strive to come up with the global environmental protection requirements, grab the momentum of domestic and foreign business opportunities.

The development of heat stabilizer, the beginning of the eighties of last century, with a large number of plastic processing machinery imports, plastic additives a variety of new technologies, new products are also a lot into China. Such as the production of soft leather LC-90 (the United States Daxiang Meihua company's cadmium / zinc catalytic foam stabilizer), for the production of foam wall paper potassium / calcium high foam stabilizer (Holland Akesu products) Wait. These products give us a new processing ideas and vision at the same time, but also China's current heat stabilizer varieties of the whole, the origin of the system. Objective analysis of the current domestic heat stabilizer pattern If the lead, cadmium products excluded from the environment-friendly products have been formed to organic tin (including complex products), calcium / zinc (that is, complex products), rare earth complex, etc. Three major systems, of course, domestic organic stabilizer has been the development, application reports. And the production and identity sense, the current calcium or zinc products ranked first; but the composite multi-functional organotin stabilizer organic tin products is a major development trend, but also in line with China's actual situation; of course, rare earth products, especially Is the introduction of rare earth / calcium zinc products is also a major bright spot.

Composite calcium and zinc heat stabilizer is the world recognized non-toxic, environmentally friendly heat stabilizer, and has a low price, good lubricity, etc., has a very broad space for development, composite calcium and zinc heat stabilizer is the use of both Synergistic effect, making it the most active field of compound stabilizers in recent years. The world's leading manufacturer of thermal stabilizers have launched the product. And domestic enterprises are in a variety of ways to catch up, such as Jiangsu Jia Ren Wo Technology, Wenzhou Tiansheng, Hebei Gray, Nanjing Jinling, Shenzhen Zhihai, Zhaoqing Dinghu and other enterprises, in powder, paste, liquid and other environmental Product development, application has made good results.

The development and application of auxiliary stabilizers is one of the hotspots of heat stabilizers. These organic compounds include phosphite, polyol, epoxy compound, β-diketone, organic stabilizer and inorganic hydrotalcite. In the organic stabilization of the research and application of materials is particularly prominent in the United States Branch of the company introduced for the processing of PVC hard products organic products - OBS. Organic stabilizers can be extracted from organic base compounds such as aminouracil, dihydropyridine and pentahedral 1,3,4-oxadiazole derivatives, which are competitively competitive and have low performance Migration, low odor, good hue, excellent transparency. Organic stabilizer stabilizer due to the inhibition of molecular chain crosslinking, in the processing of PVC products, in the high temperature and high shear under the processing time, significantly better than lead and calcium / zinc soap stabilizer system, the domestic hospital , The enterprise as early as a few years ago put a lot of people, money, things, and achieved certain results.

Since the end of 2007 to the present, due to the global financial crisis, the domestic economy also showed a downward trend, the impact of plastic products is one step earlier, in 2007, Guangdong exported toys due to paint over the recall of the US and Thailand events triggered Global "China" toy "exclusion" wave, in 2008 about plastic bags and other "white pollution" caused by the "plastic limit order" two events caused by domestic toy production fell more than double digits and 70% of plastic bags to stop the plant. Relatively speaking, the impact of the heat stabilizer industry is not great, but the impact on the industry is very far-reaching. Heat stabilizer industry to lead, tin and other metals, stearic acid as the main raw material, the price turns turns, raw material prices almost did not stop the trend, to the downstream processing and manufacturing industry to bring huge cost pressures, which we Basically in the low-profit situation of the auxiliary production enterprises, it is even worse. But we should also see the central government to start 4 trillion investment, the implementation of the implementation of the ten measures to expand domestic demand, the heat stabilizer is good news.

In the ten measures to stimulate domestic demand, the construction of major water conservancy projects will be a lot of PVC pipe and membrane materials; in the protection of housing projects, low-rent housing construction, shantytowns transformation, nomadic housing projects in the plastic doors and windows is essential ; In the city power grid transformation, railway roads and airports and other major infrastructure construction, PVC wire and cable and other basic materials, automotive industry, the revitalization of electronic information industry, will be more directly to the demand for PVC plastic products and spare parts. These projects are huge investment, and many project funds have been put in place to start implementation. To sum up the analysis, in this big cake in the heat stabilizer industry prospects are very attractive. Contrast Tian Sheng boss at the beginning of the interview according to his mastery of the primary information, has clearly predicted: the central 4 trillion investment will pull a substantial increase in the amount of PVC pipe, the increase is expected to be 5% -10%. However, from the current situation to see the growth of PVC hard products will be more than 10%.

Of course, China's thermal stabilizer enterprises in recent years faced with a variety of inflationary pressures and operational difficulties, from the deep analysis, in fact, small business scale, talent, technology, capital shortage and other issues of comprehensive complications, prices rose only Is the fuse. Therefore, in the face of the future may continue to fluctuate the price volatility, the shortage of resources and the crisis, the production enterprises in addition to relying on their limited resources for production management, market adjustment to make a fuss, the enterprise itself must be taken seriously the R & D, Investment, or through corporate mergers, cooperation, from bigger, stronger, so fine on the focus, with a new concept to meet the challenge.
