Inkqubo yokulungiselela
Eyona mithombo mibini iphambili yerayon yipetroleum kunye nebhayoloji.Ifayibha ehlaziyiweyo yirayon eyenziwe kwimithombo yebhayoloji.Inkqubo yokwenza i-mucilage iqala ngokutsalwa kwe-alpha-cellulose esulungekileyo (ekwaziwa njenge-pulp) kwimathiriyeli ye-cellulose ekrwada.Le pulp icutshungulwa nge-caustic soda kunye ne-carbon disulfide ukuvelisa i-orenji-colored cellulose sodium xanthate, ethi ke inyibilikiswe kwisisombululo se-sodium hydroxide.Ibhafu ye-coagulation yenziwe nge-asidi ye-sulfuric, i-sodium sulfate, kunye ne-zinc sulfate, kwaye i-mucilage iyahluzwa, ifudunyezwe (ibekwe kwiqondo lokushisa elikhethekileyo malunga ne-18 ukuya kwiiyure ze-30 ukunciphisa i-esterification ye-cellulose xanthate), i-defoam, kwaye emva koko imanzi. yasonta.Kwibhafu ye-coagulation, i-sodium cellulose xanthate ibola kunye ne-sulfuric acid, ekhokelela ekuvuseleleni i-cellulose, imvula, kunye nokudalwa kwe-fiber cellulose.
Ulwahlulo Isilika etyebileyo, intambo erhabaxa, umsonto weentsiba, isilika eyenziweyo engamenyeziyo
Iingenelo
Ngeempawu ze-hydrophilic (i-11% yokubuya kokufuma), i-viscose rayon lilaphu eliphakathi ukuya kwenzima elinomsebenzi oqhelekileyo ukuya komelela okuhle kunye nokuxhathisa ukukrazuka.Ngokhathalelo olufanelekileyo, olu fayibha lusenokucocwa kwaye luhlanjwe emanzini ngaphandle kombane ongatshintshiyo okanye iipilisi, kwaye alubizi kakhulu.
Iingxaki
I-elasticity ye-Rayon kunye nokomelela kwayo ayilunganga, icutheka kakhulu emva kokuhlanjwa, kwaye ikwachaphazeleka kukungunda kunye nokungunda.I-Rayon ilahlekelwa yi-30% ukuya kwi-50% yamandla ayo xa imanzi, ngoko ke kufuneka kuthathelwe ingqalelo xa ihlamba.Emva kokumisa, amandla abuyiselwa (i-viscose rayon ephuculweyo - i-high wet modulus (HWM) i-viscose fiber, akukho ngxaki enjalo).
Usebenzisa
Izicelo zokugqibela zerayon zikwimihlaba yempahla, upholstery, kunye neshishini.Imizekelo ibandakanya imiphezulu yamabhinqa, iihempe, iimpahla zangaphantsi, iidyasi, amalaphu ajingayo, amayeza, izinto ezingalukwanga, kunye nempahla yococeko.
Umahluko phakathi kwerayon
Isilika eyenziweyo inombala oqaqambileyo, irhabaxa kancinane kwaye iqinile, kunye nemvakalelo emanzi nebandayo.Xa ishwabene kwaye ingashwabenanga ngesandla, iba nemibimbi ngakumbi.Xa ithe yacandwa, igcina imigca.Xa isiphelo solwimi sifumile kwaye sisetyenziselwa ukukhupha ilaphu, i-silika eyenziweyo ilula ngokulula kwaye iphule.Xa yomile okanye imanzi, i-elasticity iyahluka.Xa iziqwenga ezibini zesilika zixutywa kunye, zinokwenza isandi esahlukileyo.Isilika ikwabizwa ngokuba “yisilika,” kwaye xa ibotshiwe yaza yakhululwa, imibimbi iye ingabonakali.Iimveliso zesilika zikwanazo zombini ezomileyo nezimanzi.
