When PA66 nylon 66 salt is prepared from diacid and two meta amine, it is necessary to strictly control the molar ratio as the molar ratio, so as to get a polymer with high molecular weight. Therefore, the mixture of adipic acid and adipamine must be mixed into nylon 66 salt in production. The preparation of nylon 66 salt is to mix adipic diamine solution and adipic acid solution at the temperature above 60 centigrade, neutralize it and precipitate after salt formation. After filtration, alcohol washing and drying, after Zui,

POM☆市場增長較快,而中國POM☆生產(chǎn)的基礎(chǔ)比較薄弱;另外POM☆是資金和技術(shù)密集型的材料類化工產(chǎn)品,中國巨大的市場引起了國外大的關(guān)注,其它國一直想以其產(chǎn)品占據(jù)中國市場,不愿轉(zhuǎn)讓技術(shù),使中國POM☆的技術(shù)水平提高緩慢,不能滿足用戶需求;再有就是長期以來,中國經(jīng)濟(jì)體制和 企業(yè)經(jīng)營機(jī)制不符合市場經(jīng)濟(jì)規(guī)律,企業(yè)不能及時(shí)獲得足夠的資金投入,制約了POM☆生產(chǎn)的發(fā)展。
POM, the market is growing fast, and the basis of China's POM production is relatively weak; in addition, POM is a material and technology intensive material chemical product. The huge market in China has aroused great concern abroad. Other countries have always wanted to occupy the Chinese market with their products, unwilling to transfer technology and improve the technical level of China's POM. Slow, can not meet the needs of the user; again, for a long time, China's economic system and enterprise operating mechanism do not conform to the law of the market economy, enterprises can not get enough capital investment in time, restricting the development of POM production.
PBT是同用工程塑料中工業(yè)化zui晚而發(fā)展zui快的一個(gè)品種,它之所以成為工程塑料的后起之秀,首先在于它具有優(yōu)良的綜合性能,以及良好的成型加工性和性能/價(jià)格相比,故此PBT塑料雖然到70年代才工業(yè)化生產(chǎn),但很快市場,現(xiàn)為五大工程塑料發(fā)展zui快的一種。
PBT is a kind of fast developing Zui in the same engineering plastics in the late industrialization of Zui. It has become a rising star of engineering plastics. First of all, it has excellent comprehensive performance and good processing property and performance / price. Therefore, the PBT plastic is not industrialized until 70s, but it is fast selling market. Now, it is a fast developing Zui for the five major engineering plastics.
