I-PA6 yenziwe ngani?I-PA6, eyaziwa ngokuthi i-polycaprolactam (Polyamide 6), iyipulasitiki yobunjiniyela evamile, eyaziwa nangokuthi inayiloni 6.Kulesi sihloko, sizohlaziya ngokuningiliziwe ukwakheka, izakhiwo, izinhlelo zokusebenza, kanye nezinzuzo kanye nobubi be-PA6, ukuze sisize abafundi bathole ukuqonda okuphelele kwezimpawu nokusetshenziswa kwalolu lwazi.
Ukwakheka kwe-PA6 kanye nenqubo yokukhiqiza
I-PA6 iyi-thermoplastic eyenziwe ngokusabela kwe-polymerisation eyindandatho ye-caprolactam. I-Caprolactam iyi-monomer etholwe ukusabela kwamakhemikhali wezinto zokusetshenziswa njenge-adipic acid ne-caprolactic anhydride, eyenza i-polymer yeketanga elide ngokusabela kwe-polymerisation. Le nto inezinga eliphakeme le-crystallinity ngakho-ke ibonisa izakhiwo ezinhle kakhulu zemishini nokuzinza kwamakhemikhali.
Izici zokusebenza ze-PA6
I-PA6 inezinhlobonhlobo zezakhiwo ezinhle kakhulu eziyenza ibe into ethandwayo yezinhlelo zokusebenza zobunjiniyela.I-PA6 inamandla aphezulu kanye nokuqina futhi iyakwazi ukumelana nezingcindezi ezinkulu zemishini.I-PA6 futhi inokumelana okuvelele kokuhuyeka nokukhathala, okuyenza ifanelekele ukukhiqiza izingxenye ezidinga isikhathi eside sokusebenza.I-PA6 futhi inokumelana okuhle kwamakhemikhali kuwoyela namafutha, ama-alkali, kanye nohlu olubanzi olusetshenziswayo lwezincibilikisi, i-PA6 futhi iyisixazululi sezinto eziningi ezisetshenziswayo. imishini yezimboni.
Izicelo ze-PA6
I-PA6 isetshenziswa ezinhlobonhlobo zezicelo zezimboni. Ukwakheka kwayo okuhle kakhulu kuyenza ilungele ukwenziwa kwezingxenye eziwumshini njengamagiya, ama-bearing, nama-slides. Ngenxa yokumelana kwayo nokuhuzuka okuphezulu, i-PA6 iphinde isetshenziswe kabanzi ekwenzeni izingxenye zezimoto ezifana namathangi kaphethiloli, ama-radiator grills nezibambo zomnyango, njll. Izakhiwo ezinhle kakhulu zokuvikela ugesi zikagesi ze-PA6 ziye zaholela ekusetshenzisweni kwayo ezinhlobonhlobo zezicelo ezindaweni zikagesi neze-elekthronikhi, njengokushefa kwekhebula kanye nokwakhiwa kwezingxenye zikagesi.
Izinzuzo kanye nokubi kwe-PA6
Naphezu kwezinzuzo zayo eziningi, i-PA6 inezinye izinto ezimbi.I-PA6 inezinga eliphezulu le-hygroscopicity, okwenza kube lula ukumunca umswakama lapho isetshenziswa ezindaweni ezinomswakama, okuholela ekunciphiseni kwezakhiwo zemishini yezinto ezibonakalayo. Lesi sici singakhawulela ukusetshenziswa kwaso kwezinye izindawo ezikhethekile. Uma kuqhathaniswa namanye amapulasitiki obunjiniyela asebenza kahle kakhulu, i-PA6 inokumelana nokushisa okuphansi futhi ngokuvamile ingasetshenziswa isikhathi eside kuphela ezindaweni zokushisa ezingaphansi kuka-80°C.
Ukuguqulwa kwe-PA6 kanye nentuthuko yesikhathi esizayo
Ukuze banqobe ukushiyeka kwe-PA6, abacwaningi bathuthukise ukusebenza kwayo ngamasu okulungisa. Isibonelo, ngokungeza imicu yengilazi noma ezinye izigcwalisi, ukuqina nokuzinza kwe-PA6 kungathuthukiswa kakhulu, ngaleyo ndlela kwandiswe ububanzi bayo bezinhlelo zokusebenza. Njengoba ubuchwepheshe buthuthuka, i-PA6 kulindeleke ukuthi idlale indima ebaluleke kakhulu emikhakheni eminingi esikhathini esizayo.
Isifinyezo
Iyini impahla ye-PA6? Njengoba kubonakala ekuhlaziyeni okungenhla, i-PA6 iyipulasitiki yobunjiniyela eguquguqukayo enezakhiwo ezinhle kakhulu zemishini kanye nokumelana namakhemikhali. Iphinde ibe nokubi njengokumunca umswakama ophezulu kanye nokumelana nokushisa okungekuhle. Ngobuchwepheshe bokuguqula, izindawo zokusetshenziswa ze-PA6 ziyakhula. Kungakhathaliseki ukuthi kusembonini yezimoto, ukukhiqizwa kwemishini, noma emkhakheni kagesi ne-elekthronikhi, i-PA6 ibonise amandla amakhulu okusebenza.
