Ukufaka isicelo se-lubricant

Ukusetshenziswa kwamafutha okugcoba ngephepha kuhlehlela ekuqaleni kwaleli khulu leminyaka. Ngaleso sikhathi, ingcina ye-pigment yephepha ngokuyinhloko yayiyiglue yezilwane noma i-casein, futhi okuqukethwe okuqinile kokumbozwa kwakuphansi kakhulu. Nakuba lezi zinamatheliso zinokunamathela okuhle nokusebenza okuhle kakhulu kokugcinwa kwamanzi, ifilimu eyakhiwe yizo i-brittle kakhulu, ngakho-ke kuyadingeka ukwengeza isithasiselo esingathuthukisa ukumelana nokugoqa nokugoba kwephepha eliboshwe kanye nebhodi. Lezi zithako zibuye zithuthukise uketshezi kanye nokulingana kwezingubo ezimanzi. Lesi sengezo sibe isigcobo sephepha.

Umsebenzi we-lubricant wokugcoba

Umsebenzi we-lubricant uyahlukahluka ngezinhlobo ezahlukene zephepha kanye nomehluko emikhubeni yokukhiqiza yomshini wephepha. Ngezinye izikhathi uketshezi lwento enamathelayo kanye nezinye izici zephepha elinamekiwe (njengokukhanya, ukushelela, ukumunca uwoyela, amandla angaphezulu, njll.) kusetshenziswa ukuhlola ukusebenza kwesigcobo. Ezinye izigaba zokuthambisa zinezici ezikhethekile zokusebenza, njengokuthi "izici zokulungisa i-viscosity", "ukumelana nokungqubuzana okuthuthukisiwe okuthuthukisiwe", "ukunamathela okumanzi okuthuthukisiwe", "ukumelana nokungqubuzana okuthuthukisiwe okumanzi", "i-ink gloss kanye nokungafinyeleli", "ipulasitiki", "ukumelana nokugoqa" kanye "nokucwebezela okuthuthukisiwe", njll.

I-lubricant efanelekile kufanele ibonise izici ezilandelayo

(1) gcoba upende futhi uthuthukise izici zokugeleza kwawo;

(2) Qinisekisa ukunamathela okushelelayo;

(3) Thuthukisa isicwebezelisi somkhiqizo oboshiwe;

(4) Ukuthuthukisa ukuphrinta kwephepha;

(5) Nciphisa imifantu nokuxebuka kwento enamathelayo lapho iphepha ligoqwa;

(6) Nciphisa noma susa impushana nge-super calender.
