Iphepha le-Kraft seliyinketho ethandwayo ngenxa yamandla alo aphezulu, ukuguquguquka, kanye nomthelela ophansi kwezemvelo.Ingaphinda isetshenziswe ngo-100% futhi ihambisana nemvelo, inomlando omude wokukhiqiza ohlanganisa imicu yokhuni, amanzi, amakhemikhali, nokushisa.Iphepha le-Kraft linamandla futhi linamandla kakhulu, okwenza lifanele izinqubo ezikhethekile.Isetshenziswa kakhulu emaphaketheni, njengamakhathoni nezikhwama zephepha, futhi kunezinhlobo ezahlukene ezihlukaniswa ngokwemvelo nenjongo yazo.
1.Yiniingabe iphepha le-kraft?
Iphepha le-Kraft libhekisela ephepheni noma ebhodini lephepha elikhiqizwa ku-pulp yamakhemikhali kusetshenziswa inqubo yokwenza i-kraft papermaking.Ngenxa yenqubo ye-kraft pulping, i-kraft paper inokuqina okuhle kakhulu, ukumelana namanzi, nokumelana nezinyembezi, futhi umbala wayo uvamise ukuba wumbala onsundu ngokuphuzi.
I-Kraft pulp inombala ojulile kunamanye amapulangwe okhuni, kodwa ingafakwa i-bleach ukuze yenze i-pulp emhlophe kakhulu.I-kraft pulp exutshwe ngokuphelele isetshenziswa ekukhiqizeni iphepha lekhwalithi ephezulu lapho amandla, ubumhlophe, kanye nokumelana nokuphuzi kubalulekile.
2. Umlando kanye nenqubo yokukhiqiza ye-Kraft Paper
Iphepha le-Kraft, into yokupakisha evame ukusetshenziswa, liqanjwe ngenqubo yalo yokudonsa.Inqubo yokwenza iphepha ye-kraft yasungulwa nguCarl F. Dahl eDanzig, ePrussia (manje eyiGdańsk, ePoland) ngo-1879. Igama elithi kraft lisuselwa egameni lesiJalimane elithi "Kraft," elisho amandla noma ubungqabavu.
Izakhi eziyisisekelo zokukhiqiza i-kraft pulp yizintambo zokhuni, amanzi, amakhemikhali, nokushisa.I-Kraft pulp ikhiqizwa ngokuxuba imicu yokhuni ngesisombululo se-caustic soda ne-sodium sulfide bese uyipheka ku-digester.
Ngemva kokubhekana nezinqubo ezihlukahlukene zokukhiqiza ezifana nokukhulelwa, ukupheka, ukuxubha kwe-pulp, ukushaya, ukulinganisa, ukucwenga, ukuhlanzwa, ukuhlunga, ukwakha, ukuphelelwa amandla kwamanzi kanye nokucindezela, ukomisa, ukulinganisa, nokujika, kanye nokulawula inqubo eqinile, i-kraft pulp ekugcineni iguqulwa ibe. iphepha le-kraft.
3. I-Kraft Paper vs. Iphepha Elivamile
Abanye bangase baphikise ngokuthi kuyiphepha nje, ngakho-ke yini ekhetheke kakhulu ngephepha le-kraft?
Ngamagama alula, iphepha le-kraft linamandla.
Ngenxa yenqubo ye-kraft pulping okukhulunywe ngayo ekuqaleni, i-lignin eyengeziwe ikhishwa emicu ye-kraft pulp wood, ishiya ngemuva imicu eminingi.Lokhu kunikeza iphepha ukumelana nokukhala nokuqina.
Iphepha le-kraft elingaxutshiwe livame ukuba nezimbotshana kunephepha elivamile, okungase kuphumele emiphumeleni yokuphrinta empofu kancane.Kodwa-ke, le porosity iyenza ifaneleke ngokwedlulele izinqubo ezithile ezikhethekile, njengokugqamisa noma ukugxiviza okushisayo.
4.Izicelo ze-Kraft Paper ku-Packaging
Namuhla, i-kraft paper isetshenziselwa ikakhulukazi amabhokisi kathayela nasekukhiqizeni izikhwama zephepha ngaphandle kwezingozi zepulasitiki, njengalezo ezisetshenziselwa usimende, ukudla, amakhemikhali, izimpahla zabathengi kanye nofulawa.
Ngenxa yokuqina nokusebenza kwawo, amabhokisi kathayela enziwe ngephepha le-kraft aziwa kakhulu embonini yokulethwa kwezidingo kanye nempahla.Lawa mabhokisi avikela ngempumelelo imikhiqizo futhi angamelana nezimo ezinzima zokuhamba.Ukwengeza, ukusebenza kahle kwezindleko zephepha le-kraft kukwenza kube ukukhetha okufanele ekuthuthukisweni kwebhizinisi.
Amabhokisi ephepha e-Kraft nawo avame ukusetshenziswa yizinkampani ukufeza imigomo yentuthuko esimeme, ebonisa ngokucacile imizamo yokuvikela imvelo ngokusebenzisa ukubukeka kwe-rustic nokuluhlaza kwephepha le-kraft elinsundu.Iphepha le-Kraft linohlelo olubanzi lwezicelo futhi linganikeza okuhlukahlukeneukupakisha okushaizixazululo embonini yanamuhla yokupakisha.
5. Izinhlobo ze-Kraft Paper
Iphepha le-Kraft livame ukugcina umbala walo wokuqala onsundu ngokuphuzi, okulenza lifaneleke ukukhiqizwa kwezikhwama nephepha lokugoqa.Kunezinhlobo ezahlukene zephepha le-kraft elisekelwe ezintweni zalo kanye nokusebenza.Iphepha le-Kraft yigama elijwayelekile lephepha futhi alinawo amazinga athile.Ngokuvamile ihlukaniswa ngokwezakhiwo zayo kanye nokusetshenziswa okuhlosiwe.
Ngombala, iphepha le-kraft lingahlukaniswa libe yiphepha le-kraft lemvelo, iphepha le-kraft elibomvu, iphepha elimhlophe le-kraft, iphepha le-matte kraft, iphepha le-kraft elicwebezelayo elinohlangothi olulodwa, iphepha le-kraft elinemibala emibili, nokunye.
Ngokusekelwe ekusetshenzisweni kwalo, iphepha le-kraft lingahlukaniswa libe yiphepha lokupakisha le-kraft, iphepha le-kraft elingangeni manzi, i-kraft ye-beveled, i-rust-proof kraft paper, iphepha le-kraft elinephethini, i-insulating kraft paperboard, izitika ze-kraft, nokuningi.
Ngokusho kokwakheka kwalo, iphepha le-kraft lingaphinda lihlukaniswe libe yiphepha le-kraft eligaywe kabusha, i-kraft core paper, i-kraft base paper, i-kraft wax paper, i-wood pulp kraft paper, i-composite kraft paper, nokunye.
Izinhlobo Ezivamile ze-Kraft Paper
1. Iphepha Le-Kraft Elinamekwe Elingaxutshiwe (CUK)
Le nto ibhekwa njengenguqulo eyisisekelo kakhulu yephepha le-kraft.Ayingeni "i-bleaching" noma ezinye izithasiselo zamakhemikhali, ngaphandle kwamakhemikhali asetshenziswa kunqubo ye-kraft pulping.Ngenxa yalokho, yaziwa nangokuthi i-kraft eqinile engaxutshiwe noma i-sulfite, ehlanganisa u-80% we-virgin fiber wood pulp/cellulose kraft pulp.Ibonisa ukumelana nezinyembezi okuhle kakhulu nokuqina okuphezulu ngaphandle kokujiya ngokweqile.Eqinisweni, iyona mncane kunawo wonke ama-substrates okupakisha we-kraft paper.
2. Iphepha Le-Kraft Eliqinisiwe Eliqinile (SBS)
Nakuba iphepha le-kraft elingaxutshiwe libhekwa njengelihambisana kakhulu nemvelo ngenxa yombala walo wemvelo kanye nokuntuleka kokwelashwa kwamakhemikhali, kungase kungabi njalo ukukhetha okuhle kwezinhlelo ezithile zokusebenza, njengokupakishwa kwemikhiqizo yokunethezeka noma ephezulu.Kulezi zimo, iphepha le-kraft eline-bleached lingase likhethwe ngoba linobuso obushelelezi kanye nokubukeka okugqamile, okungathuthukisa ikhwalithi yokuphrinta futhi kunikeze ukubukeka nokuzwakala kwe-premium eyengeziwe.
3. Ibhodi Elisetshenziswe Kabusha Elinamanzi (CRB)
Ibhodi elakhiwe kabusha elakhiwe ngephepha le-kraft elingu-100% eligaywe kabusha.Ngenxa yokuthi ayikhiqizwa ngemicu emsulwa, ukucaciswa kwayo nokubekezelelana kwayo kuncane kunaleyo yephepha le-kraft eliqinile elicijile.Kodwa-ke, iphepha le-kraft eligaywe kabusha liyi-substrate yokupakisha eshibhile, elenza lifaneleke kahle izinhlelo zokusebenza ezingadingi ukumelana nokukhala okukhulu noma amandla, njengamabhokisi okusanhlamvu.Emabhokisini kathayela, izinhlobo eziningi zingatholakala ngokungeza izingqimba zephepha le-kraft.
