I-fiber encibilikayo emanzini enezinga lokushisa eliphansi ithathwa njenge-PVA njengempahla eluhlaza futhi yamukelwa indlela yokuphotha ijeli enezici ezilandelayo:
1. Izinga lokushisa elincibilikayo emanzini.Ayishiyi insalela lapho incibilika emanzini ku-20-60 ℃.Indlela ye-Sodium sulfide ingakhiqiza kuphela imicu evamile encibilika ekushiseni okuphezulu okungu-80 ° C noma ngaphezulu.
2. Ifanele ukucutshungulwa kwendwangu ngenxa yamandla ayo aphezulu efayibha, ingxenye yesiphambano se-fiber eyindilinga, ukuzinza okuhle kwe-dimensional, ukuminyana komugqa okumaphakathi kanye nobude.
3. Ukumelana kahle nezinambuzane kanye nesikhutha, ukumelana kahle nokukhanya, ukuncipha kwamandla okuncipha kakhulu kuneminye imicu lapho uchayeka isikhathi eside elangeni.
4. Ayinabuthi futhi ayinabungozi kumuntu nemvelo.Ukungabikho kwe-sodium sulfide kuholela engozini yothuli lwamahhala ngesikhathi sokuphotha.
