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.Kwesinye isikhathi i-fluidity ye-coating nezinye izakhiwo zephepha elinamekiwe (njengokukhanya, ukushelela, ukumuncwa kukawoyela, amandla angaphezulu, njll.) kusetshenziswa ukuhlola ukusebenza kwesigcobo.Ezinye izigaba zokuthambisa zinezici ezikhethekile zokusebenza, njengokuthi "izimpawu zokulungiswa kwe-viscosity", "ukuthuthukiswa kokumelana nokungqubuzana okomile", "ukunamathela okumanzi okuthuthukisiwe", "ukumelana nokungqubuzana okuthuthukisiwe okumanzi", "i-ink gloss nokungafinyeleli", "ipulasitiki", "ukugoqa ukumelana" kanye "nesicwebezelisi esithuthukisiwe", 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.
