Manje, ingcindezi ekuvikelweni kwemvelo iyanda.Imicu yenayiloni ikhuthaza ukukhiqizwa okuhlanzekile, futhi inqubo yokufaka imibala engenamanzi iye yadonsa ukunakwa okwengeziwe.Okulandelayo ulwazi oluthile olubalulekile lwenqubo yokufaka imibala engenamanzi.
1. Inqubo yombala we-anhydrous yentambo yesi-6 yenayiloni
Njengamanje, umbala we-thepolyamide filament embonini yenayiloni yaseShayina usetshenziswa kakhulu ukudaya idiphu kanye nokudaya amaphedi esigabeni sakamuva sokuphotha.Odayi abasetshenziswayo bahlanganisa odayi abahlakazayo kanye nodayi be-asidi.Le ndlela ayinakuhlukaniswa kuphela emanzini, kodwa futhi inokusetshenziswa kwamandla aphezulu kanye nezindleko eziphezulu.Ukungcoliswa kokuphrinta nokudaya amanzi angcolile esigabeni sakamuva kuyinkinga kakhulu.
I-pigment isetshenziswa njenge-ejenti yombala ukuze kulungiswe i-masterbatch yombala, encibilika ngokuphothwa ngamaships enayiloni angu-6 ukuze kutholwe intambo enombala yenayiloni engu-6.Yonke inqubo yokuphotha ayidingi iconsi lamanzi, futhi iluhlaza futhi ayihambisani nemvelo.Kuyinqubo esetshenziswa kakhudlwana evele eminyakeni yamuva, kodwa ayiphelele ngokwemibandela yokuphotha kanye nezakhiwo zokulinganisa.
Inqubo yombala kadayi we-vacuum sublimation isebenzisa odayi abahlakazayo noma izingulube ezilula kalula njengezimibalabala, ezifakwa ngaphansi kwegesi ngaphansi kwezimo eziphakeme zokushisa noma ze-vacuum, ezikhangiswa ebusweni bemicu yenayiloni engu-6 bese isakazwa ku-fiber ukuze kuqedelwe inqubo yokudaya.
2. Izinzuzo zenqubo yokufaka imibala enayiloni engu-6 engenamanzi
Le nqubo ayiwadli amanzi, kodwa kunezinhlobo ezimbalwa kakhulu zamadayi nezingulube ezingasetshenziswa ukufaka imibala enayiloni 6 imicu yenayiloni.Ukulawulwa kwejubane le-sublimation kuzothinta izinga kanye nokuthathwa kodayi ngezinga elithile, okudinga imishini ephezulu.Nakuba ingekho inkinga yokungcoliswa kwamanzi, ukungcoliswa kwezinto zokusebenza, indawo ezungezile kanye nabasebenzi ngeke kushaywe indiva.
I-Supercritical carbon dioxide daying ayiwadli amanzi.Odayi be-Hydrophobic disperse bangancibilika ku-carbon dioxide ebaluleke kakhulu ukuze bafake imibala yemicu inayiloni.Uma kuqhathaniswa nokudaywa kwamanzi, isikhathi sokudaya sifushane.Kuphela ngokulungisa ukucindezela nokushisa, yonke inqubo yokudaya ingaqedwa kudivayisi eyodwa, kodwa ayikwazi ukuxazulula ngokuphumelelayo umphumela wama-oligomers ekusebenzeni kokudaya ngesikhathi senqubo yokudaya.
