Ingaba iphepha lenziwe nge-cellulose?

iphepha lenziwe ngokuyintlokoi-celluloseiifayibha, ezithathwe kwizinto zezityalo ezifana ne-pulp yomthi, umqhaphu, okanye ezinye izityalo ezine-fibrous. Ezi fayibha ze-cellulose ziyacutshungulwa kwaye zenziwe zibe ngamaphepha amancinci ngothotho lweendlela zonyango lwe-mechanical kunye neekhemikhali. Inkqubo iqala ngokuvunwa kwemithi okanye ezinye izityalo ezinomxholo ophezulu we-cellulose. Emva koko, i-cellulose ikhutshwa ngeendlela ezahlukeneyo ezifana ne-pulping, apho umthi okanye izinto zesityalo ziqhekeka zibe yi-pulp ngeendlela ze-mechanical okanye ze-chemical.

Nje ukuba i-pulp ifunyenwe, iyaqhubeka nokulungiswa ukuze kususwe ukungcola okufana ne-lignin kunye ne-hemicellulose, okunokwenza buthathaka ulwakhiwo lwephepha kwaye kubangele ukutshintsha kombala. Ukufiphaza kungasetyenziselwa ukwenza i-pulp ibe mhlophe kwaye kuphucule ukukhanya kwayo. Emva kokucocwa, i-pulp ixutywa namanzi ukwenza i-slurry, emva koko isasazwa kwiscreen se-wire mesh ukuze kukhutshwe amanzi angaphezulu kwaye kwenziwe i-mat encinci yeefayibha. Le mat iyacinezelwa kwaye yomiswe ukuze kwenziwe amaphepha ephepha.

I-cellulose ibalulekile kwinkqubo yokwenza iphepha ngenxa yeempawu zayo ezikhethekileyo. Inika iphepha amandla nokuqina ngelixa ikwavumela ukuba liguquguquke kwaye libe lula. Ukongeza, iifayibha ze-cellulose zinamandla aphezulu emanzini, nto leyo enceda iphepha ukuba lifunxe i-inki kunye nezinye izinto ezimanzi ngaphandle kokuqhekeka.

Ngelixai-celluloseEyona nto iphambili ephepheni, ezinye izongezo zingafakwa ngexesha lenkqubo yokwenza iphepha ukuphucula iimpawu ezithile. Umzekelo, izizalisi ezifana nodongwe okanye i-calcium carbonate zingongezwa ukuphucula ukungabonakali kunye nokuguda, ngelixa izinto zokulinganisa ezifana nesitatshi okanye iikhemikhali zokwenziwa zingasetyenziswa ukulawula ukufunxwa kwephepha kunye nokuphucula ukumelana kwalo namanzi kunye ne-inki.
