Ingabe iphepha lenziwe nge-cellulose?

iphepha lenziwe ngokuyinhloko ngei-celluloseimicu, etholakala ezintweni zezitshalo ezifana ne-pulp yokhuni, ukotini, noma ezinye izitshalo ezinemicu. Lezi micu ye-cellulose ziyacutshungulwa futhi zenziwe amashidi amancane ngokusebenzisa uchungechunge lwezindlela zokwelapha zemishini namakhemikhali. Inqubo ngokuvamile iqala ngokuvuna izihlahla noma ezinye izitshalo ezinokuqukethwe okuphezulu kwe-cellulose. Ngemuva kwalokho, i-cellulose ikhishwa ngezindlela ezahlukahlukene ezifana ne-pulping, lapho ukhuni noma izinto zesitshalo zihlukaniswa zibe yi-pulp ngezindlela zemishini noma zamakhemikhali.

Uma i-pulp isitholiwe, iyaqhubeka nokucutshungulwa ukuze kususwe ukungcola okufana ne-lignin ne-hemicellulose, okungenza buthaka isakhiwo sephepha futhi kubangele ukushintsha kombala. Ukufiphaza kungasetshenziswa futhi ukwenza i-pulp ibe mhlophe futhi kuthuthukiswe ukukhanya kwayo. Ngemva kokuhlanzwa, i-pulp ixutshwa namanzi ukuze kwenziwe i-slurry, bese isakazwa esikrinini se-wire mesh ukuze kukhishwe amanzi amaningi futhi kwakhiwe i-mat encane yezintambo. Le mat ibe isicindezelwa futhi yomiswe ukuze kwakhiwe amaphepha.

I-cellulose ibalulekile enkambisweni yokwenza iphepha ngenxa yezakhiwo zayo ezihlukile. Inikeza iphepha amandla nokuqina ngenkathi ivumela ukuthi liguquguquke futhi libe lula. Ngaphezu kwalokho, imicu ye-cellulose inamandla amakhulu emanzini, okusiza iphepha ukuthi limunce uyinki nezinye izinto eziwuketshezi ngaphandle kokuqhekeka.

Ngesikhathii-celluloseNjengoba kuyiyona ingxenye eyinhloko yephepha, ezinye izithasiselo zingafakwa ngesikhathi senqubo yokwenza iphepha ukuze kuthuthukiswe izakhiwo ezithile. Isibonelo, izigcwalisi ezifana nobumba noma i-calcium carbonate zingangezwa ukuze kuthuthukiswe ukungabonakali kanye nokushelela, kuyilapho izinto zokulinganisa ezifana nesitashi noma amakhemikhali okwenziwa zingasetshenziswa ukulawula ukumuncwa kwephepha nokuthuthukisa ukumelana kwalo namanzi noyinki.
