ISINGENISO NGEPHEPHA

Iphepha lokusiza

iphepha eliyinhloko elisetshenziswa ekunyatheliseni izincwadi nomagazini. Ifanele imisebenzi ebalulekile, izincwadi zesayensi nobuchwepheshe, amajenali ezemfundo nezinto zokufundisa, njengephepha lombhalo. Iphepha lokukhulula ngokusho kokwakheka kwephepha lingahlukaniswa ngamabanga angu-1,2,3 kanye nama-4. Inombolo yephepha egameni lekhwalithi yephepha, inani elikhulu lephepha libi kakhulu. Iphepha Lokuphrinta Lokusiza lisetshenziselwa ikakhulukazi ukuphrinta usizo. Izici zaleli phepha ziyefana ne-newsprint, kodwa azifani ncamashi. Isakhiwo se-fiber yephepha lokukhulula sifana kakhulu, ngesikhathi esifanayo, igebe phakathi kwemicu ligcwaliswa inani elithile le-filler ne-rubber, futhi futhi ngemva kwe-bleaching, okwenza leli phepha likwazi ukuzivumelanisa nezimo ezinhle zokunyathelisa. Nakuba ukumuncwa kukayinki kungekuhle njenge-newsprint, kodwa inezici ezifanayo zokumunca uyinki, ukumelana namanzi nokuba mhlophe kwephepha kungcono kune-newsprint.

Newsprint

elibizwa nangokuthi iphephandaba Elimhlophe, liyiphepha elikhulu lamaphephandaba nezincwadi. Ifanele amaphephandaba, amaphephabhuku, izincwadi zokufunda, amahlaya kanye namanye amaphepha ombhalo. I-Newsprint inezici ezilandelayo: iphepha lilula futhi liyanwebeka, ukumuncwa kahle kukayinki, okuqinisekisa ukuthi uyinki ungagxilwa ephepheni. Ngemuva kwe-calendering, izinhlangothi zombili zephepha zibushelelezi futhi aziguquki, ukuze izinhlangothi zombili ze-imprint zicace futhi zigcwele; kukhona izinga elithile lamandla omshini; ukukhanya okuhle; ilungele Ukuphrinta kwe-Rotary ngesivinini esikhulu. Lolu hlobo lwephepha lukhiqizwa kusuka ku-mechanical wood pulp (noma enye i-pulp yamakhemikhali) , equkethe inani elikhulu le-Lignin nokunye ukungcola, okungafanelekile ukugcina isikhathi eside. Isikhathi sokugcina side kakhulu, iphepha lizobe liphuzi i-Brittle, ukumelana namanzi okumpofu, akufanelekile ukubhala.
