Ngoku, uxinzelelo kukhuseleko lokusingqongileyo luyanda.Imicu yenayiloni ikhuthaza imveliso ecocekileyo, yaye inkqubo yokufaka imibala engenamanzi iye yatsala ingqalelo engakumbi nangakumbi.Oku kulandelayo lulunye ulwazi olufanelekileyo lwenkqubo yombala engenamanzi.
1. Inkqubo yombala we-nayiloni eyi-6 ye-nayiloni
Okwangoku, umbala we-thepolyamide filament kumzi mveliso wenayiloni waseTshayina usetyenziswa kakhulu ukudipha ukudaya kunye nokudaya ipadi kwinqanaba lamva lokusonta.Iidayi ezisetyenziswayo ziquka iidayi ezisasazwayo kunye nedayi yeasidi.Le ndlela ayinakwahlulwa kuphela emanzini, kodwa inokusetyenziswa kwamandla aphezulu kunye neendleko eziphezulu.Ungcoliseko lokuprinta kunye nokudaya amanzi amdaka kwinqanaba lamva luyingxaki kakhulu.
I-pigment isetyenziswa njenge-ejenti yombala ukulungiselela i-masterbatch yombala, enyibilikayo-isolulwe ngeetshiphusi zenayiloni ezi-6 ukuze kufumaneke umsonto onemibala yenayiloni emi-6.Yonke inkqubo yokusonta ayifuni ithontsi lamanzi, kwaye iluhlaza kwaye ihambelana nokusingqongileyo.Yinkqubo esetyenzisiweyo ethe yavela kwiminyaka yamuva nje, kodwa ayifezekanga ngokubhekiselele kwi-spinnability kunye neempawu zokulinganisa.
Inkqubo vacuum sublimation yedayi Umbala isebenzisa iidayi ukusasaza okanye pigments ngokulula sublimable njengoko colorants, leyo sublimated ibe irhasi phantsi kobushushu obuphezulu okanye iimeko vacuum, adsorbed kumphezulu inayiloni 6 imisonto kunye diffused kwifayibha ukugqiba inkqubo yokudaya.
2. Izinto eziluncedo zenayiloni 6 inkqubo yombala engenamanzi
Le nkqubo ayiwatyi amanzi, kodwa zimbalwa kakhulu iindidi zedayi kunye nebala ezinokuthi zisetyenziswe ukufaka imibala kwinayiloni emi-6 yemicu.Ukulawulwa kwesantya se-sublimation kuya kuchaphazela umgangatho kunye nokufakwa kwedayi kwinqanaba elithile, elifuna izixhobo eziphezulu.Nangona kungekho ngxaki yongcoliseko lwamanzi, ungcoliseko lwezixhobo, okusingqongileyo kunye nabasebenzi abanakungahoywa.
I-Supercritical carbon dioxide idayin ayiwatyi amanzi.I-Hydrophobic disperse dayes inokunyibilika kwi- supercritical carbon dioxide ukuze ifake imibala kwimicu yenayiloni.Xa kuthelekiswa nokudaya kwamanzi, ixesha lokudaya lifutshane.Kuphela ngokulungelelanisa uxinzelelo kunye nokushisa, yonke inkqubo yokudaya ingagqitywa kwisixhobo esinye, kodwa ayikwazi ukucombulula ngempumelelo umphumo we-oligomers ekusebenzeni kokudaya ngexesha lokudaya.
