Izici Ezibalulekile Zezinto Ezibalulekile
Ukuthembeka kwale nto kuvela enqubweni ye-kraft, ephatha ngamakhemikhali izingcezu zokhuni ukuze zincibilikise i-lignin ngenkathi ishiya imicu eqinile ye-cellulose ingathintekile. Kubalulekile ukuhlukanisa iphepha elijwayelekile le-kraft elinsundu (elivame ukusetshenziselwa ukusonga nezikhwama) nephepha le-kraft elinsundu elijwayelekile (elivame ukusetshenziselwa ukugoqa nezikhwama)ibhodi eliqinile le-kraftnoma ibhodi lephepha, elisetshenziswa kakhulu ukukhiqiza amabhokisi anezinti. Uma kuhlolwa imiqulu ejwayelekile evela ku-umhlinzeki wesibonelo, abathengi bavame ukubona izisindo eziyisisekelo (isilinganiso sobuningi bephepha kanye nobukhulu) kusukela ku-50 GSM yokusonga okulula kuze kufike ku-150 GSM yezinhlelo zokusebenza ezisindayo.
Abathengi kumele balinganise izindleko kanye nokusimama kwemikhiqizo besebenzisa amazinga embonini (njenge-TAPPI noma i-ASTM): i-virgin pulp inikeza ukumelana okukhulu kokudabuka kodwa inenani eliphezulu lemali kanye nelemvelo, i-kraft equkethe izinto ezisetshenzisiwe inikeza inketho eyindilinga, engabizi kakhulu enamandla aphansi esakhiwo, kanye nokuxubana kwe-fiber exubile kulinganisela kokubili. Imvelo engaxutshiwe igcina ukuqina kwe-fiber ngokungayifaki i-bleaching yamakhemikhali enzima.
Ukulinganiselwa Kwezinto Ezibalulekile:Naphezu kwamandla ayo, iphepha le-kraft elinsundu linezithiyo ezingokwemvelo. I-kraft engagqokwanga ibucayi kakhulu emswakama futhi isengozini yokonakala kwe-UV ngokuhamba kwesikhathi. Ngaphezu kwalokho, amazinga ajwayelekile angagqokwanga ngokuvamile awafaneleki ukuthintana ngqo nokudla ngaphandle kwezithiyo ezikhethekile. Ngenkathi iphepha le-kraft elihlanzekile lingasetshenziswa kabusha kabanzi—ngokuvamile lifinyelela amazinga okubuyisa angaphezu kuka-70% emifuleni yemfucuza yezentengiselwano yesifunda esemisiwe—ama-lamination noma izimbozo ezisindayo ezisetshenziswa ukunqoba imikhawulo yomswakama zivame ukwenza iphepha lingaphinde lisetshenziswe. Abathengi kumele baqaphele ukuthi izimangalo zokusebenzisa kabusha kanye nokwenza umquba zincike kakhulu kwingqalasizinda yendawo; ngisho nezinto eziklanyelwe ukubola ngaphansi kwezimo zokufaka umquba ezimbonini zingagcina sezindaweni zokulahla udoti, njengoba izindawo zokufaka umquba ezimbonini zingatholakali kuyo yonke indawo.
Izicelo Ezivamile Zezentengiselwano
Ngenxa yokuthi kulula ukusika, ukugoqa, ukuphrinta, kanye nokunamathisela, leli phepha lisebenza emikhakheni eminingi yezentengiselwano. Lisebenza njengomgogodla oqinile wezikhwama zokuthenga ezitolo,izinto zokuthumela ze-e-commerce, kanye nokugcwaliswa kwesikhala esivikelayo.
