Menene Hanyoyin Polymerization na Nailan 6?

Tare da haɓaka sabbin fasaha, samar da nailan 6 ya shiga cikin manyan manyan sabbin fasahohi.Bisa ga daban-daban amfani, da polymerization tsari na nailan 6 za a iya raba zuwa wadannan.

1. Hanyar polymerization mataki biyu

Wannan hanya ta ƙunshi hanyoyi guda biyu na polymerization, wato pre-polymerization da hanyoyin da suka biyo baya, wanda yawanci ana amfani da shi wajen samar da masana'anta na masana'anta tare da babban danko.Hanyoyi biyu na polymerization sun kasu kashi-kashi pre-polymerization pressurization da post-polymerization decompression.A cikin tsarin samarwa, ana aiwatar da matsi ko ƙwanƙwasa magani bisa ga kwatancen lokacin polymerization, mutum a cikin samfurin da ƙananan ƙarar poly.Gabaɗaya, hanyar lalatawar post-polymerization ya fi kyau, amma yana buƙatar ƙarin saka hannun jari, da farashi mai girma, sannan babban matsin lamba da matsa lamba na al'ada dangane da farashi.Koyaya, farashin aiki na wannan hanyar yana da ƙasa.A cikin pre-polymerization pressurization da post-polymerization decompression samar da hanyoyin, a lokacin da matsa lamba matakin, da sinadaran da ake hadawa da su, sa'an nan kuma sanya duk a cikin reactor, sa'an nan da ruwa-unlocking zobe dauki da wani bangare na polymerization dauki. a takamaiman zafin jiki.Tsarin shine halayen endothermic.Zafin yana samuwa a saman ɓangaren bututun polymer.A lokacin aiwatar da matsa lamba, polymer ya zauna a cikin bututun polymer na wani lokaci sannan ya shiga cikin polymerizer, inda danko na polymer da aka samar zai kai kimanin 1.7.

2. Hanyar polymerization mai ci gaba a matsa lamba na al'ada

Ana amfani da wannan hanyar don samar da kintinkiri na gida na nailan 6. Features: An karɓa mafi girma ci gaba da polymerization tare da zafin jiki na har zuwa 260 ℃ da kuma lokacin polymerization na 20 hours.Ana samun ragowar oligomer a cikin sashin lokacin da ruwan zafi ya saba da halin yanzu.Hakanan ana ɗaukar tsarin rarrabawar DCS da bushewar iskar ammonia.Tsarin dawo da monomer yana ɗaukar fasahohin ci gaba da haɓaka tasirin sakamako uku da maida hankali da katsewar distillation da tattarawar ruwan da aka fitar.Abũbuwan amfãni daga cikin hanyar: Kyakkyawan ci gaba da aiki na samarwa, babban fitarwa, babban ingancin samfurin, ƙananan yanki da aka shagaltar da aikin samarwa.Hanyar ita ce fasaha mai mahimmanci a cikin samar da kintinkiri na gida na yanzu.

3. Hanyar wucin gadi autoclave polymerization

An yi amfani da shi sosai wajen samar da ƙananan robobin injiniya.Ma'auni na samarwa shine 10 zuwa 12t / d;Fitowar autoclave guda ɗaya shine 2t/batch.Gabaɗaya, matsa lamba a cikin tsarin samarwa shine 0.7 zuwa 0.8mpa, kuma danko zai iya kaiwa 4.0, da 3.8 a lokaci na al'ada.Domin idan danko ya yi yawa, abin da ake fitarwa zai yi ƙasa kaɗan.Ana iya amfani da shi don samar da pa 6 ko pa 66. Hanyar tana da tsari mai sauƙi na samarwa, wanda ke da sauƙin canza nau'in kuma mai sauƙi don samarwa.
