China Drying Network News national tool enzyme standardization 2012 annual meeting and the second working meeting was held recently in Fujian, the meeting on the "tool enzyme standard system framework" draft, "restriction endonuclease A" national standard draft, "restriction coagulation "Enzyme" draft national standards and other discussions. The enzyme enzyme is one of the most commonly used consumables in biotechnology research. It is a series of enzymes that can cleave, link, amplify, and modify genes, and is a basic material for modern biotechnology research. At present, only a few companies in the world have a complete kit enzyme production system. The enzyme enzyme technology has been monopolized by foreign countries and has become a bottleneck in the development of China's biological industry. The meeting proposed that in the future more attention should be paid to the standardization work of the tool enzyme industry, actively follow the development of foreign tool enzyme technology standards, introduce advanced key production and test equipment, carry out standardized research on tool enzymes, and formulate standards for tool enzyme product quality and detection methods. The right to speak of the technology, as soon as possible to end the history of China's long-term dependence on imported tools.
The Plasticizer DINP is di isononyl phthalate (DINP), which is formed by esterification of phthalic anhydride and isononyl alcohol. DINP is a general plasticizer. One of the main raw materials of DINP, isononanol (INA)
Advantages of DINP plasticizers:

Compared with DOP, DINP has a larger molecular weight and a longer carbon chain. Therefore, it has better aging performance, anti migration performance, anti extraction performance and higher high temperature resistance. Correspondingly, under the same conditions, the plasticizing effect of DINP was slightly worse than that of DOP. It is generally believed that DINP is more environmentally friendly than DOP.
DINP, as a main plasticizer, is widely used in various soft PVC products. Such as wire and cable, film, PVC leather, PVC floor leather, toys, shoes, edge banding, sheath, wig, tablecloth, etc. DINP also has a small number of applications in some rubber products and coatings.
DINP is an oily liquid under normal conditions and is insoluble in water. Generally, it is transported by tank trucks, and small batches are transported by iron drums or special plastic drums.
2. Plastics are easier to coat, spray and dip
3. Higher durability, more resistant to outdoor low temperature
4. Compatible with auxiliary plasticizers, thus further reducing costs
5. Low volatility, which helps to reduce volatile in the process and improve working conditions
6. Lower density, lower energy consumption and higher extrusion output than DOP
