Common Types of Nylon and Their Differences
large more 数 朋友, or for/regarding its in certain types nylon comparison understanding. comprehensive property comparison understanding nylon can can more, especially is has 朋友不 is especially 清楚, is what has nylon water property very large, has nylon material water property has comparison small. therefore, small is large 家汇编 summary: Common nylon property can large ratio 拼, from full 局 角 degree comparison nylon material.
一, nylon development history
首先, large 家 认识一 lower nylon development history:
1935 year 2 month 28 day 卡罗瑟斯 in 实验室首次 combined formed nylon PA66. 1938 year 10 month 27 day DuPont company positive 式宣布 world upper types combined formed fiber positive 式诞生, 并命名 is nylon.
1938 year PA6首先由 Germany I.G.Farbon company P.Schlach R&D formed 功, 1943由该 company achieve industrial 化, market amount to nylon market formed.
1941 year PA610由 DuPont company development formed 功, 于20世纪50 year 代开始 production and application. PA610 in nylon 生家族 in has very important 位.
1947 year France 阿托菲 nano utilizing 天然蓖麻油 as is raw materials production PA11, 1955 year achieve industrial production.
1958 year PA1010首先 is in Shanghai 赛璐珞厂研 made formed 功.
1962 year DuPont development 出间位芳纶PA1313, 并于1967 year achieve industrial production.
1966 year DuPont also made for 位芳纶PA1414, 于1971 year product achieve industrial 化.
PA612首先由 DuPont company development formed 功.
PA9T由 Kuraray R&D formed 功.
PA6T首先由 Mitsui Chemicals R&D formed 功.
1966 year PA12由 Germany AG company achieve industrial 化.
1985 year PA46由 Netherlands 国家矿业 company development.
2006 year Kingfa for PA10T进行 R&D.
currently nylon application 广泛就 used for automotive parts, power/electricity, electronics device parts, machine industrial, precision device and other.
二, 命名规则
understanding history, again from 命名 角 degree, let large 家进一步认识 nylon.
（1）由 inner amine ring polymerization nylon,称 is nylon n,简写 is PAn. is: 如ε- caprolactam ring polymerization to polymer, is PA6, ω-氨基十一 acid combined formed polymer is PA11.
（2）由 binary amine and binary acid polycondensation to polymer,称 is nylon mn,简写 is PAmn, m is heavy mono binary amine carbon 原子数, n is heavy mono in binary acid carbon 原子数, 通式:
（3） use heavy 复 二 amine or acid table/sheet 示, 如间苯二甲 amine is MXDA, 故间苯二甲 amine and adipic acid polymer is nylon MXD6.
（4） copolymer nylon is use upper methods nylon 名称组 combined, main/primary formed separation nylon 名称放 in front 面, nylon 6 and nylon 66 copolymer nylon is 6/66; main/primary formed separation is nylon 66, is 66/6.
