Imbali kunye neNkqubo yoMveliso weKraft Paper
Iphepha le-Kraft lisetyenziswa kakhulu ekupakisheni, elibizwa ngegama lenkqubo yokukhupha iphepha le-kraft. Ubugcisa bephepha le-kraft baqanjwa nguCarl F. Dahl eDanzig, ePrussia, eJamani ngo-1879. Igama lalo livela kwisiJamani: i-Kraft ithetha amandla okanye ubomi.
Izinto ezisisiseko zokwenza i-pulp yesikhumba senkomo yi-fiber yomthi, amanzi, iikhemikhali kunye nobushushu. I-pulp yenkomo iveliswa ngokuxuba ii-fiber zomthi kunye nesisombululo se-caustic soda kunye ne-sodium sulfide kwaye zitshiswe nge-steamer.
I-Pulp idlula kwiinkqubo zokuvelisa kunye nolawulo lweenkqubo ezifana nokufunxwa, ukupheka, ukufunxwa kwe-pulp, ukubethelwa, ubungakanani, ukumhlophe, ukucocwa, ukuhluzwa, ukubunjwa, ukuphelelwa ngamanzi emzimbeni kunye nokucinezelwa, ukomiswa, ukukrwelwa kwekhalenda, kunye nokujijelwa ukuze ekugqibeleni kuveliswe iphepha le-kraft.
Ukusetyenziswa kwephepha le-kraft ekupakisheni
Kule mihla, iphepha le-kraft lisetyenziswa kakhulu kwiibhokisi zekhadibhodi ezirhabaxa, kunye namaphepha angengobungozi eplastiki asetyenziswa kwiingxowa zephepha ezifana nesamente, ukutya, iikhemikhali, izinto ezisetyenziswa ngabantu, kunye neengxowa zomgubo.
Ngenxa yokuqina nokusebenza kakuhle kwephepha le-kraft, iibhokisi zekhadibhodi ezirhabaxa zithandwa kakhulu kushishino lothutho olukhawulezayo. Iibhokisi zinokukhusela iimveliso kakuhle kwaye zimelane neemeko ezinzima zothutho. Ukongeza, ixabiso kunye neendleko zihambelana nophuhliso lwamashishini.
Iibhokisi zephepha le-Kraft zikwasetyenziswa rhoqo ngamashishini ukufezekisa iinjongo zophuhliso oluzinzileyo, kwaye amanyathelo okusingqongileyo abonakaliswa ngokucacileyo ngembonakalo yasemaphandleni neyakudala yephepha le-kraft elimdaka. Iphepha le-Kraft linoluhlu olubanzi lokusetyenziswa kwaye linokubonelela ngeendlela ezahlukeneyo zokupakisha ezintsha kushishino lwanamhlanje lokupakisha.
