Nubuhe buryo bwa Polymerisation kuri Nylon 6?

Hamwe niterambere ryikoranabuhanga rishya, umusaruro wa nylon 6 winjiye murwego rwikoranabuhanga rinini-rishya.Ukurikije uburyo butandukanye, inzira ya polymerisation ya nylon 6 irashobora kugabanywa muribi bikurikira.

1. Uburyo bubiri bwa polymerisation

Ubu buryo bugizwe nuburyo bubiri bwa polymerisiyonike, aribwo pre-polymerisation nuburyo bwa nyuma ya polymerizasiya, ubusanzwe bukoreshwa mugukora imyenda yinganda zinganda hamwe nubwiza bwinshi.Uburyo bubiri bwa polymerisiyasi bugabanijwemo pre-polymerisation ya pression na decompression nyuma ya polymerisation.Mubikorwa byo kubyara, kuvura igitutu cyangwa decompression bikorwa ukurikije igereranya ryigihe cya polymerisation, umuntu mubicuruzwa nubunini buke bwa poly.Muri rusange, uburyo bwa decompression nyuma ya polymerisation nibyiza, ariko bisaba ishoramari ryinshi, nigiciro kinini, gikurikirwa numuvuduko mwinshi nigitutu gisanzwe mubiciro.Ariko, ikiguzi cyo gukora cyubu buryo kiri hasi.Muburyo bwa pre-polymerisation hamwe nuburyo bwo gukora nyuma ya polymerisiyasi ya decompression, mugihe cyumuvuduko, ibintu byumusaruro bivangwa hanyuma byose bigashyirwa muri reaction, hanyuma reaction ya feri yo gufungura amazi hamwe na polymerisation igice. ku bushyuhe bwihariye.Inzira nigisubizo cya endothermic reaction.Ubushyuhe buherereye mugice cyo hejuru cya polymer.Mugihe cyo gukanda, polymer iguma mumiyoboro ya polymer mugihe runaka hanyuma ikinjira muri polymerizer, aho ubwiza bwa polymer bwakozwe buzagera kuri 1.7.

2. Uburyo bukomeza bwa polymerisation kumuvuduko usanzwe

Ubu buryo bukoreshwa mugukora lente yo murugo ya nylon 6. Ibiranga: Polimerisiyumu nini ikomeza hamwe nubushyuhe bugera kuri 260 time hamwe na polymerisation kumasaha 20.Oligomer isigaye mu gice iboneka iyo amazi ashyushye ajyanye numuyoboro.Sisitemu yo gukwirakwiza DCS hamwe no gukama umwuka wa amoniya nabyo byemewe.Inzira yo kugarura monomer ikoresha tekinoroji yo gukomeza guhumeka inshuro eshatu hamwe no guhunika hamwe no guhagarika amazi hamwe no gukusanya amazi yakuwe.Ibyiza byuburyo: Imikorere ihebuje ikomeza yumusaruro, umusaruro mwinshi, ubuziranenge bwibicuruzwa, agace gato gakorwa mubikorwa byo gukora.Uburyo ni tekinoroji isanzwe muburyo bwo gukora urugo rwimbere.

3. Ubwoko bwigihe gito autoclave polymerisation

Irakoreshwa cyane mugukora plastike yubuhanga buto.Igipimo cy'umusaruro ni 10 kugeza 12t / d;Ibisohoka bya autoclave imwe ni 2t / batch.Muri rusange, umuvuduko mubikorwa byo kubyara ni 0.7 kugeza 0.8mpa, kandi viscosity irashobora kugera kuri 4.0, na 3.8 mugihe gisanzwe.Ibyo ni ukubera ko niba viscosity ari ndende cyane, ibisohoka bizaba bike.Irashobora gukoreshwa kubyara pa 6 cyangwa pa 66. Uburyo bufite uburyo bworoshye bwo gukora, bworoshye guhindura ubwoko kandi bworoshye kubyara umusaruro.
