Ingabe iphepha lenziwe nge-cellulose?

iphepha ngokuyinhloko lenziwa kusukelai-celluloseimicu, etholakala ezintweni zezitshalo ezifana ne-wood pulp, ukotini, noma ezinye izitshalo ezine-fibrous. Le micu ye-cellulose iyacutshungulwa bese yenziwa amashidi amancane ngochungechunge lwemithi yokwelapha namakhemikhali. Inqubo ngokuvamile iqala ngokuvuna izihlahla noma ezinye izitshalo ezinokuqukethwe kwe-cellulose ephezulu. Khona-ke, i-cellulose ikhishwa ngezindlela ezihlukahlukene ezifana ne-pulping, lapho ukhuni noma impahla yesitshalo ihlukaniswa ibe yi-pulp ngokusebenzisa izindlela zemishini noma zamakhemikhali.

Uma i-pulp isitholiwe, iqhubeka nokucutshungulwa ukuze isuse ukungcola okufana ne-lignin ne-hemicellulose, engenza buthaka ukwakheka kwephepha futhi kubangele ukushintsha kombala. Ukuhlanza kungase futhi kusetshenziswe ukwenza i-pulp ibe mhlophe futhi kuthuthukiswe ukukhanya kwayo. Ngemva kokuhlanzwa, i-pulp ixutshwa namanzi ukuze yenze udaka, bese lusakazwa esikrinini se-wire mesh ukuze kukhishwe amanzi amaningi bese kwakheka umata omncane wemicu. Lo mata ube esecindezelwa futhi omiswe ukuze kwakheke amaphepha.

I-Cellulose ibalulekile enqubweni yokwenza iphepha ngenxa yezakhiwo zayo eziyingqayizivele. Inikeza amandla nokuqina ephepheni ngenkathi futhi ivumela ukuthi iguquguquke futhi ibe lula. Ukwengeza, imicu ye-cellulose ihlobene kakhulu namanzi, okusiza iphepha ukuthi limunce uyinki nolunye uketshezi ngaphandle kokubola.

Ngenkathii-celluloseingxenye eyinhloko yephepha, ezinye izithasiselo zingase zifakwe phakathi nenqubo yokwenza iphepha ukuze kuthuthukiswe izakhiwo ezithile. Isibonelo, izigcwalisi ezifana nobumba noma i-calcium carbonate zingase zengezwe ukuze kuthuthukiswe ukukhanya nokushelela, kuyilapho ama-ejenti okulinganisa afana nesitashi noma amakhemikhali okwenziwa angasetshenziswa ukuze kulawulwe ukumunca kwephepha futhi kuthuthukiswe ukumelana kwalo namanzi noyinki.
