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.
