Iphepha le-Kraft libe lolona khetho lukhethiweyo ngenxa yamandla alo aphezulu, ukuguquguquka, kunye nefuthe eliphantsi lokusingqongileyo.I-100% iphinda isetyenziswe kwaye ihambelana nokusingqongileyo, kunye nembali ende yemveliso ebandakanya imicu yomthi, amanzi, iikhemikhali kunye nobushushu.Iphepha le-Kraft linamandla kwaye linamandla ngakumbi, okwenza ukuba lilungele iinkqubo ezikhethekileyo.Isetyenziswa kakhulu ekupakisheni, njengeebhokisi kunye neengxowa zephepha, kwaye kukho iindidi ezahlukeneyo ezihlelwe ngokwendalo kunye nenjongo yazo.
1.Yintoniliphepha lekraft?
Iphepha le-Kraft libhekisela kwiphepha okanye i-paperboard eveliswe kwi-pulp yekhemikhali usebenzisa inkqubo ye-kraft papermaking.Ngenxa yenkqubo ye-kraft pulping, iphepha le-kraft linokomelela okugqwesileyo, ukunganyangeki kwamanzi, kunye nokumelana nokukrazula, kwaye umbala walo uqhelekile ukuba ngumbala otyheli-mdaka.
I-pulp ye-Kraft inombala onzulu kunezinye iinkuni, kodwa inokuthi ifakwe i-bleached ukudala i-pulp emhlophe kakhulu.I-kraft pulp efakwe i-bleached ngokupheleleyo isetyenziswa ekuveliseni iphepha elikumgangatho ophezulu apho amandla, ubumhlophe, kunye nokumelana nokuba tyheli kubalulekile.
2. IMbali kunye neNkqubo yoMveliso yePhepha leKraft
Iphepha leKraft, into esetyenziswa ngokuqhelekileyo, libizwa ngokuba yinkqubo yalo yokucofa.Inkqubo yokwenza iphepha lekraft yaqanjwa nguCarl F. Dahl eDanzig, ePrussia (ngoku eyiGdańsk, ePoland) ngo-1879. Igama elithi kraft lithatyathwe kwigama lesiJamani elithi "Kraft," elithetha amandla okanye amandla.
Izinto ezisisiseko zokwenza i-kraft pulp ziintsinga zomthi, amanzi, iikhemikhali kunye nobushushu.I-kraft pulp iveliswa ngokuxuba imicu yomthi kunye nesisombululo se-caustic soda kunye ne-sodium sulfide kunye nokupheka kwi-digester.
Emva kokwenza iinkqubo ezahlukeneyo zokuvelisa ezifana nokufakwa, ukupheka, ukuxutywa kwe-pulp, ukubetha, ukulinganisa, ukwenza mhlophe, ukucocwa, ukuhlolwa, ukwenza, ukuphelelwa ngamanzi emzimbeni kunye nokucinezela, ukomisa, ukulinganisa, kunye nokujika, kunye nolawulo olungqongqo lwenkqubo, i-kraft pulp ekugqibeleni iguqulwa ibe iphepha le-kraft.
3. Iphepha leKraft vs
Abanye banokuphikisa ukuba liphepha nje, ngoko yintoni ekhethekileyo malunga nephepha le-kraft?
Ngamagama alula, iphepha le-kraft linamandla.
Ngenxa yenkqubo ye-kraft pulping ekhankanywe ngaphambili, i-lignin eninzi iyasuswa kwi-kraft pulp fibers, ishiya ngasemva imicu emininzi.Oku kunika iphepha ukuxhathisa ukukrazula kunye nokuqina.
Iphepha le-kraft elingaxutywanga lihlala libukhali kunephepha eliqhelekileyo, nto leyo enokukhokelela kwiziphumo zoshicilelo ezihlwempuzekileyo.Nangona kunjalo, le porosity iyenza ifaneleke kakhulu kwiinkqubo ezithile ezikhethekileyo, ezinje nge-embossing okanye isitampu esishushu.
4.Izicelo zePhepha leKraft kwiPackaging
Namhlanje, iphepha le-kraft lisetyenziselwa ikakhulu kwiibhokisi zentsimbi kunye nokuveliswa kweengxowa zephepha ngaphandle kweengozi zeplastiki, ezifana nezo zisetyenziselwa i-samente, ukutya, iikhemikhali, iimpahla zabathengi kunye nomgubo.
Ngenxa yokuqina kwayo kunye nokusebenza kwayo, iibhokisi ezenziwe ngamatye ezenziwe nge-kraft paper zithandwa kakhulu kushishino olucacileyo kunye nokuhanjiswa kwezinto.Ezi bhokisi zikhusela ngokufanelekileyo iimveliso kwaye zinokumelana neemeko zothutho ezinzima.Ukongezelela, i-cost-effectiveness of kraft paper yenza kube yinto efanelekileyo yophuhliso lweshishini.
Iibhokisi zephepha le-Kraft nazo zihlala zisetyenziswa ziinkampani ukufezekisa iinjongo zophuhliso oluzinzileyo, ezibonisa ngokucacileyo iinzame zokukhusela okusingqongileyo ngokubonakala kwe-rustic kunye nekrwada yephepha le-brown kraft.Iphepha le-Kraft linoluhlu olubanzi lwezicelo kwaye linokubonelela ngeendlela ezahlukeneyoukupakishwa okutshaizisombululo kushishino lokupakisha lwanamhlanje.
5. Iintlobo zePhepha leKraft
Iphepha le-Kraft lihlala ligcina umbala walo wokuqala otyheli-mdaka, okwenza ukuba ilungele ukuveliswa kweengxowa kunye nephepha lokusonga.Kukho iintlobo ezahlukeneyo zephepha le-kraft ngokusekelwe kwiipropati kunye nokusetyenziswa kwayo.Iphepha le-Kraft ligama eliqhelekileyo lephepha kwaye alinayo imigangatho ethile.Ihlelwa ngokubanzi ngokweempawu zayo kunye nokusetyenziswa kwayo.
Ngombala, iphepha le-kraft lingahlelwa ngokwendalo ye-kraft paper, iphepha le-kraft elibomvu, iphepha le-kraft elimhlophe, iphepha le-matte kraft, iphepha le-gloss le-kraft elinecala elinye, iphepha le-kraft elinemibala emibini, kunye nabanye.
Ngokusekwe kwizicelo zalo, iphepha le-kraft linokohlulwa libe liphepha lokupakisha le-kraft, iphepha le-kraft elingangenwa ngamanzi, iphepha le-kraft le-beveled, i-rust-proof kraft paper, iphepha le-kraft elinepateni, i-insulating kraft paperboard, izitikha ze-kraft, kunye nokunye.
Ngokokwakheka kwemathiriyeli, iphepha le-kraft linokuphinda lahlulwe libe liphepha le-kraft elisetyenzisiweyo, i-kraft core paper, i-kraft base base paper, i-kraft wax paper, i-wood pulp kraft paper, i-composite kraft paper, kunye nabanye.
Iintlobo eziqhelekileyo zePhepha leKraft
1. IPhepha leKraft eliCatyiswe Lingafakwanga Ibleached (CUK)
Esi sixhobo sithathwa njengeyona nto isisiseko sephepha le-kraft.Ayenzi "bleaching" okanye ezinye izongezo zekhemikhali, ngaphandle kweekhemikhali ezisetyenziswa kwinkqubo yekraft pulping.Ngenxa yoko, ikwabizwa ngokuba yikrafti eqinileyo engaxutywanga okanye i-sulfite, equka i-80% ye-virgin fibre wood pulp/cellulose kraft pulp.Ibonisa ukuxhathisa okugqwesileyo kweenyembezi kunye nokuqina okuphezulu ngaphandle kobunzima obugqithisileyo.Ngapha koko, yeyona nto incinci kuzo zonke ii-kraft paper packaging substrates.
2. IPhepha leKraft eliQinisekileyo eliLiqina (SBS)
Ngelixa iphepha le-kraft elingaxutywanga lithathwa njengelinobungane ngakumbi kokusingqongileyo ngenxa yombala walo wendalo kunye nokungabikho konyango lwemichiza, isenokungasoloko ilukhetho olufanelekileyo kwizicelo ezithile, njengokupakishwa kwezinto zodidi oluphezulu okanye ezikumgangatho ophezulu.Kule meko, iphepha le-kraft elixutywe nge-bleached linokukhethwa ngenxa yokuba linomgangatho ococekileyo kunye nembonakalo eqaqambileyo, enokuphucula umgangatho wokushicilela kwaye ibonelele ngokubonakalayo kunye nokuvakalelwa.
3. Ibhodi eRecycled Recycled (CRB)
Ibhodi eqatywe ireyisayikilishwe yenziwe nge-100% yephepha lekraft elisetyenzisiweyo.Ngenxa yokuba ayiveliswanga kwimicu enyulu, ukucaciswa kwayo kunye nokunyamezela kwayo kungaphantsi kwezo zephepha eliqinileyo lekraft elijikisiweyo.Nangona kunjalo, iphepha le-kraft elisetyenzisiweyo kwakhona liyi-substrate yokupakisha ephantsi kweendleko eziphantsi, okwenza ukuba ifaneleke kakuhle kwizicelo ezingadingi ukuxhathisa okukhulu kweenyembezi okanye amandla, afana neebhokisi ze-cereal.Kwiibhokisi ze-corrugated, iintlobo ezininzi zinokufumaneka ngokungeza iileyile zephepha le-kraft.
