Ngemva kweminyaka yokuzijwayeza ukukhiqiza, inkampani yethu, i-Highsun Synthetic Fiber Technologies Co., Ltd., kancane kancane yathola umthelela wokushisa kwebhokisi elishisayo ekugwebeni, amandla kanye nokudaya inayiloni 6.
1. Ithonya enayiloni 6 crimping
Ngaphansi kwezimo zokukhiqiza zesilinganiso sokunwebeka izikhathi ezingu-1.239, D/Y ka-2.10 kanye nesivinini esingu-700m/min, ukuncipha kwe-crimp kanye nokuzinza kwe-crimp kukhuphuka ngokunyuka kwezinga lokushisa ebangeni elithile.Lokhu kungenxa yokuthi i-plasticity ye-fiber iyathuthukiswa ngokunyuka kwezinga lokushisa, okwenza kube lula ukukhubazeka.Ngakho inayiloni 6 ithambile futhi ikhubazekile ngokuphelele.Nokho, uma izinga lokushisa liphansi kakhulu (ngaphansi kuka-182 ℃), izinga lecrimp kanye nokuzinza kwe-crimp yento enayiloni 6 kuba phansi nakho.Umcu uthambile futhi unelastic, obizwa ngokuthi usilika kakotini.Uma izinga lokushisa liphezulu kakhulu (ngaphezu kuka-196 ℃), umcu ocutshunguliwe uba qinile futhi uqine.Lokhu kungenxa yokuthi imicu iba brittle ngaphansi kwezinga lokushisa eliphezulu, okuholela emiculweni ehlanganiswa ndawonye ibe imicu eqinile.Ngakho-ke, i-crimp shrinkage iyancipha kakhulu.
2. Ithonya enayiloni 6 amandla
Phakathi nenqubo yokukhiqiza, kwatholakala ukuthi izinga lokushisa lebhokisi elishisayo libuye libe nethonya elikhulu emandleni enayiloni 6. Ngaphansi kwezimo zobuchwepheshe zejubane lokulayisha i-630m / min, isilinganiso sokwelula izikhathi ezingu-1.24 kanye ne-D / Y 2.03, ukungezwani kokusonta kunciphisa futhi ukungezwani okungaguquki nakho kuncipha ngokwanda kwezinga lokushisa, okubangelwa ukuthamba kwefayibha ekushiseni okuphezulu.Emazingeni okushisa aphansi kakhulu, amandla ayanda ngokwanda kwezinga lokushisa, kodwa ehla ngokunyuka kwezinga lokushisa (193℃).Lokhu ikakhulukazi ngoba ekushiseni okuphansi kakhulu, ikhono lomsebenzi lama-molecule e-fiber liyakhula ngokukhuphuka kwezinga lokushisa, okunciphisa ukucindezeleka kwangaphakathi ohlelweni lokuguqulwa kwe-thermal, kwenza kube lula ukuguqula futhi kwandise amandla e-filament.Kodwa-ke, ngokukhula okuqhubekayo kwezinga lokushisa, ukuma kwe-amorphous ku-fiber kulula ukuhoxiswa.Lapho izinga lokushisa lifinyelela ku-196 ℃, imicu ekhiqizwayo iba minyene futhi iqine futhi ingabonakali kahle.Ngemva kokuhlola okuningi, kwatholakala ukuthi inayiloni 6 yayinamandla amakhulu kakhulu lapho izinga lokushisa lebhokisi elishisayo lalingu-187℃.Vele, lokhu kufanele kulungiswe ngokuya ngesivinini esikhulu sokulayisha se-POY enayiloni.Ngokusho kokuhlangenwe nakho, ukungcoliswa kwamafutha kanye nothuli kuzonamathela ebhokisini elishisayo ngokuncipha kokuhlanzeka komshini, okuzonciphisa ukusebenza kahle kokushisa.
3. Ithonya lokudaya inayiloni 6
Uma izinga lokushisa ebhokisini elishisayo liphansi, inayiloni 6 inobucwebe obuphansi, ukuhambisana okuqinile kokudaya, kanye nokujula kokudaya okuphezulu.Ngokuphambene nalokho, izinga lokushisa eliphezulu lebhokisi elishisayo libangela ukudaya okukhanyayo kanye nokuthatha udayi ophansi wenayiloni 6. Ngenxa yokuthi izinga lokushisa elibonisiwe lomshini ngezinye izikhathi liphambuka kakhulu ekushiseni okulinganiselwe, lapho izinga lokushisa lilungiswa libe ngu-210 ° C ekukhiqizeni kwangempela, ukubukeka kanye nezinkomba zomzimba zenayiloni 6 zinhle, kodwa umphumela wombala mubi.
