Waba uzi mubyukuri imyenda ya acetate?
Fibre ya Acetate, ikomoka kuri acide acetike na selile ikoresheje esterification, ni fibre yakozwe numuntu yigana cyane imico ihebuje yubudodo.Ubu buhanga buhanitse bwimyenda itanga umwenda ufite amabara meza, isura nziza, hamwe no kumva neza.Imiterere yimiti niyumubiri ituma ibintu byinshi kandi biramba kubikorwa bitandukanye.
Kubijyanye nimiterere yimiti, fibre acetate yerekana imbaraga zidasanzwe zirwanya alkaline na acide, bigatuma ihitamo neza kubidukikije byinshi.Irangi ryayo, ariko, irerekana ikibazo kidasanzwe, kubera ko amarangi gakondo ya selile afite aho ahurira na fibre acetate, bigatuma kuyisiga bigoye.
Imiterere yumubiri wa acetate fibre irusheho kwiyongera.Hamwe nubushyuhe bwiza bwumuriro, fibre irashobora kwihanganira ubushyuhe bugera kuri 185 ° C mbere yuko igera mubushyuhe bwikirahure, hamwe na 310 ° C mbere yo gushonga.Mugihe kigaragaza kugabanuka gake mumazi abira, kuvura ubushyuhe bwo hejuru birashobora guhindura imbaraga nuburabyo, bisaba gufata neza kugirango ubungabunge ubusugire bwarwo.
Ikigaragara ni uko fibre ya acetate nayo ifite ubuhanga bworoshye, busa nubudodo nubwoya, byiyongera kubintu byinshi kandi byiza.
Gusobanukirwa imiterere yihariye ya fibre acetate ningirakamaro kugirango yongere ubushobozi bwayo mu nganda zinyuranye, uhereye kumyambarire n'imyenda kugeza kuyungurura ndetse nibindi.Ubushobozi bwayo bwo kwigana imico ihebuje yubudodo mugihe itanga ibyiza bitandukanye mubijyanye na chimique na physique ituma ishakishwa-ibikoresho kubintu byinshi.Mugihe ikoranabuhanga no guhanga udushya bikomeje gutera imbere mubikorwa byo gukora imyenda, fibre acetate ihagaze nkubuhanga nubuhanga bwinshi bwimikorere yabantu.
