Ukugcotshwa kwesicelo sokugcoba

Ukusetshenziswa kwamaphepha okuthambisa izinsuku zibuyele emuva ekuqaleni kwaleli khulu leminyaka. Ngaleso sikhathi, ukunamathela kwephepha lokuhlanganiswa kwephepha lePhepha kwakuyi-glue noma i-casein yesilwane, nokuqukethwe okuqinile kwe-coating kwakuphansi kakhulu. Yize lezi zinhloso zinokunamathela okuhle nokusebenza okuhle kakhulu kokugcinwa kwamanzi, ifilimu eyakhiwa yibo i-brittle kakhulu, ngakho-ke kuyadingeka ukufaka isengezo esingathuthukisa ukuqina kwephepha lokugoqa kanye nebhodi. Lezi izengezo zibuye zithuthukise uketshezi nokulingana kwezingubo ezimanzi. Lesi sengezo saba luthatho samaphepha.

Ukugcotshwa komsebenzi

Umsebenzi wokugcoba uyahlukahluka ngezinhlobo ezahlukene zamaphepha kanye nokwehluka kwemikhuba yokukhiqiza ye-Paper Mill. Kwesinye isikhathi uketshezi lwenhlanganisela kanye nezinye izakhiwo zephepha elihlanganisiwe (njenge-gloss, bushelelezi, ukumunca uwoyela, amandla angaphezulu, njll.) Asetshenziselwa ukuhlola ukusebenza kwe-lubricant. Ezinye izigaba zokuthambisa zinezici ezikhethekile zokusebenza, ezifana "nezimpawu zokulungiswa kwe-viscosity", "zithuthukise ukumelana okulomile", "i-ink gloss yokuphikisana", "i-ink gloss kanye nokungapheli", Ukumelana "kanye" ne-gloss ethuthukisiwe ", njll.

I-lubricant ekahle kufanele ikhombise izakhiwo ezilandelayo

(1) gcoba ngopende futhi uthuthukise izici zayo zokugeleza;

(2) qinisekisa ukuhlanganiswa okubushelelezi;

(3) Thuthukisa isicwebezelisi somkhiqizo ohlanganisiwe;

(4) Thuthukisa ukuphrintwa kwephepha;

(5) Yehlisa imifantu kanye nokutholwa kokuhlanganiswa lapho iphepha ligoqwa;

(6) Yehlisa noma ususe i-powder ku-super calender.
