Imicu yokwenziwa

Inqubo yokulungiselela
Imithombo emibili eyinhloko ye-rayon yimithombo ye-petroleum ne-biological.I-fiber evuselelwe kabusha i-rayon eyenziwe ngemithombo yezinto eziphilayo.Inqubo yokwenza i-mucilage iqala ngokukhishwa kwe-alpha-cellulose emsulwa (eyaziwa nangokuthi i-pulp) kusuka kuzinto ze-cellulose eluhlaza.Le pulp ibe isicutshungulwa nge-caustic soda ne-carbon disulfide ukuze kukhiqizwe i-cellulose sodium xanthate enombala osawolintshi, bese incibilika kusixazululo se-sodium hydroxide exutshiwe.I-coagulation bath yenziwe nge-sulfuric acid, i-sodium sulfate, ne-zinc sulfate, futhi i-mucilage iyahlungwa, ifudunyezwe (ibekwe ezingeni lokushisa elicacisiwe cishe amahora angu-18 kuya kwangu-30 ukunciphisa i-esterification ye-cellulose xanthate), ikhishwe, bese imanzi. iphothiwe.Kubhavu wokuhlanganisa, i-sodium cellulose xanthate ibola ne-sulfuric acid, okuholela ekuvuseleleni kabusha kwe-cellulose, imvula, nokudala i-cellulose fiber.

Ukuhlelwa Usilika ocebile, intambo eqinile, intambo yezinsiba, usilika wokwenziwa ongacwebezeli

Izinzuzo
Ngezimfanelo ze-hydrophilic (11% ukubuya komswakama), i-viscose rayon iyindwangu yomsebenzi ophakathi nendawo ukuya esindayo enamandla avamile ukuya kwakahle kanye nokumelana nemihuzuko.Ngokunakekelwa okufanele, le fibre ingase ihlanzwe futhi iwashwe emanzini ngaphandle kogesi ongashintshi noma amaphilisi, futhi ayibizi.

Ukubi
Ukunwebeka nokuqina kweRayon akukuhle, incipha kakhulu ngemva kokuwashwa, futhi iyakwazi ukungenwa yisikhunta kanye nesikhutha.I-Rayon ilahlekelwa u-30% kuya ku-50% wamandla ayo uma imanzi, ngakho-ke kufanele kuqikelelwe lapho ugeza.Ngemuva kokumisa, amandla abuyiselwa (i-viscose rayon ethuthukisiwe - i-high wet modulus (HWM) i-viscose fiber, ayikho inkinga enjalo).

Isebenzisa
Izicelo zokugcina ze-rayon zisemikhakheni yezingubo zokugqoka, i-upholstery, nezimboni.Izibonelo zifaka iziqongo zabesifazane, amahembe, izingubo zangaphansi, amajazi, izindwangu ezilengayo, amakhemisi, ama-nonwovens, nezimpahla zokuhlanzeka.

Umehluko phakathi kwe-rayon
Usilika wokwenziwa unokukhanya okukhanyayo, ukuthungwa okumahhadla nokuqinile, kanye nomuzwa omanzi nokubandayo.Uma ishwabene futhi ingashwabanisi ngesandla, iba nemibimbi eyengeziwe.Uma isicaba, igcina imigqa.Lapho ukuphela kolimi kumanziswa futhi kusetshenziselwa ukukhipha indwangu, usilika wokwenziwa uqondisa kalula futhi uhlephule.Uma yomile noma imanzi, ukunwebeka kuyahluka.Lapho izingcezu ezimbili zikasilika zihlikihlwa ndawonye, ​​zingakhipha umsindo ohlukile.Usilika waziwa nangokuthi “usilika,” futhi lapho usuboshiwe bese uyakhululwa, imibimbi iyancipha ukubonakala.Imikhiqizo kasilika nayo inokunwebeka okomile nokumanzi.
