Poland epoxy chain technology (1) 0 replies,254 views

#1

Poland has a good development of the industrial chain of epoxy resin, epoxy resin, according to the Chinese Association () to experts, the process has advanced, can produce a variety of high performance epoxy resin. In particular, the new epoxy technology (ICSO and Organika-Sarzyna Chemical Company, jointly developed in 2003), has been in the Polish Nowa Sarzyna achieve capacity of 12,000 tons / year of commercial production line, process the application of patents. This new invention attended the 52nd, 55th Brussels, "Research and Industrial Innovation International Invention Exhibition", and received silver medal. Prior to the development by the ICSO and Sarzyna epoxy technology in 1999 to obtain the production license in Iran, and in Bandar Imam of the implementation of its production capacity of 10,000 tons / year of liquid and solid resin. The technology worked in Brussels, Moscow, Beijing, Seoul, Nurnburg be an international exhibition held over medals. Including epichlorohydrin, bisphenol A and epoxy resin technology in 2002, the President of Poland won the economic prize.

First, the epoxy resin
1, advanced technology
Poland epoxy resin industry, advanced technology, according to China Association of epoxy resin () experts, mainly in the following areas:
Products of high quality, low hydrolyzable chlorine content, bright colors;
Product quality and repeatability;
Of environmentally friendly, do not spill gas elimination process, **** can be recovered from the solution, there is no spillage of organic matter occurs;
Raw material consumption and low consumption of common projects;
Addition polymerization process using a high activity catalyst.

2, the product quality
The process can produce a variety of high performance epoxy resin. China Epoxy Resin Industry Association () experts prepared the following table lists the Epidian6, Epidian012, Epidian 011B3 kinds of resin, typical parameters:

3, the process described
New epoxy technology is ICSO and Organika-Sarzyna Chemical Company, jointly developed in 2003, and has been in the Polish Nowa Sarzyna achieve capacity of 12,000 tons / year of commercial production line. According to the China Association of epoxy resin () to experts, the application of new technology patents.
(1) liquid epoxy resin (Epidian 6) bisphenol A and epichlorohydrin by the sodium hydroxide, water and other solvent under the conditions of condensation generated. Synthesis consists of two steps:
` In the first step, the epichlorohydrin with bisphenol A in the solvent react. In the condensation phase, the operating conditions is to ensure that minimize the side effects of epichlorohydrin;
a desalination acidification occurs in the second step reaction, step through the reaction of chlorine content in the resin can be reduced. In this step, only a solvent. As a result of the existence of this new type of solvent, the reaction can be done under mild conditions, thereby reducing the side effects of resin and sodium hydroxide.
b After the resin was washed desalting acidizing. Phase out of cleaning waste water, can further be used, and solvent recovery in the organic phase. Condensation reactions are intermittent and desalination acidification way completed. Solvent distillation process is continuous.
( 2) the solid epoxy resin ( Epidian 012) and brominated epoxy resin (Epidian011B) is accomplished through the addition polymerization, in the process, bisphenol A (TBBPA separately by the A) conditions in the high activity catalyst with Epidian 6 react. This process required, which can be intermittent or continuous.

4, reference plant
Poland Organika-Sarzyna chemical, liquid and solid resin production capacity of 12,000 Tons / year.

5, other
This new invention, attended the 52nd and the 55th Brussels, "Research and Industrial Innovation International Invention Exhibition", and received silver medal.
Previously developed by the ICSO and Sarzyna epoxy resin technology in 1999 to obtain the production license in Iran, and in Bandar Imam of the implementation of its production capacity of 10,000 tons / year of liquid and solid resin. According to the China Association of epoxy resin () to experts, the technology worked in Brussels, Moscow, Beijing, Seoul, Nurnburg be an international exhibition held over medals. Including epichlorohydrin, bisphenol A and epoxy resin technology in 2002, the President of Poland won the economic prize.
