INTSHAYELELO NGEPHEPHA

Iphepha loncedo

iphepha eliyintloko elisetyenziswa ekushicileleni uncedo lweencwadi namaphephancwadi. Ifanelekile kwimisebenzi ebalulekileyo, iincwadi zesayensi kunye nezobuchwepheshe, iijenali zezifundo kunye nezixhobo zokufundisa, ezifana nephepha lokubhaliweyo. Iphepha loncedo ngokokwakhiwa kwephepha linokwahlulwa libe ngamabakala angama-1, 2, 3 no-4. Inani lephepha egameni lomgangatho wephepha, inani elikhulu lephepha libi kakhulu. Iphepha lokuprinta loNcedo lisetyenziswa ikakhulu ekushicileleni uncedo. Iimpawu zeli phepha zifana ne-newsprint, kodwa azifani ncam. I-fiber ye-fiber ye-fiber ye-relief ifana kakhulu, ngexesha elifanayo, i-gap phakathi kwee-fibers izaliswe ngumlinganiselo othile wokuzalisa kunye ne-rubber, kwaye emva kwe-bleaching, eyenza eli phepha likwazi ukuziqhelanisa kakuhle nokushicilela. Nangona ukufunxa kwayo nge-inki kungalunganga njengoshicilelo lweendaba, kodwa ineempawu ezifanayo zokufunxa i-inki, ukuxhathisa kwamanzi kunye nobumhlophe bephepha kungcono kunoshicilelo lweendaba.

Newsprint

elikwabizwa ngokuba liphephandaba eliMhlophe, lelona phepha liphambili kumaphephandaba neencwadi. Ifanele amaphephandaba, amaphepha-ncwadi, iincwadi zezifundo, iincwadi ezihlekisayo kunye namanye amaphepha okubhaliweyo. I-Newsprint inezi mpawu zilandelayo: iphepha lilula kunye ne-elastic, i-inki efakwe kakuhle, eqinisekisa ukuba inki inokulungiswa kwiphepha. Emva kwe-calendering, amacala omabini ephepha agudileyo kwaye angabonakali, ukwenzela ukuba macala omabini e-imprint acacile kwaye agcwele; kukho iqondo elithile lamandla omatshini; opacity kakuhle; ilungele Ushicilelo lweRotary olukhawulezayo. Olu hlobo lwephepha luveliswa kwi-pulp ye-mechanical wood (okanye enye i-pulp yeekhemikhali) , equkethe inani elikhulu le-Lignin kunye nezinye izinto ezingcolileyo, ezingafanelekanga ukugcina ixesha elide. Ixesha lokugcina lide kakhulu, iphepha liya kuba li-Yellowing Brittle, ukunganyangeki kwamanzi, akufanelekile ukubhala.
