Coating lubricant application

Kushandiswa kwemafuta ekuzora mapepa kunotangira pakutanga kwezana rino remakore. Panguva iyoyo, chinonamira chepepa pigment coating chainyanya kunama yemhuka kana casein, uye iyo yakasimba yemukati yaive yakadzikira. Kunyangwe zvinonamira izvi zvine kunaka kwekunamira uye kuita kwakanakisa kwekuchengetedza mvura, iyo firimu yakaumbwa navo ine brittle, saka zvinodikanwa kuwedzera chinongedzo chinogona kuvandudza kupeta nekupeta kuramba kwepepa rakavharwa nebhodhi. Izvi zvinowedzera zvakare zvinovandudza fluidity uye kuenzana kwemachira akanyorova. Ichi chinowedzera chakava mafuta epepa.

Basa rekuzora rinosiyana nemhando dzakasiyana dzemapepa uye misiyano yemaitiro ekugadzira echigayo. Dzimwe nguva kunyungudika kwejira uye zvimwe zvinhu zvebepa rakaputirwa (sekupenya, kutsvedzerera, kunyudza mafuta, kusimba kwepamusoro, nezvimwewo) zvinoshandiswa kuongorora kushanda kwemafuta. Mamwe mapoka emafuta ane hunyanzvi hwekuita hunhu, hwakadai se "viscosity gadziriso maitiro", "yakavandudzwa yakaoma friction resistance", "yakagadziridzwa wet adhesion", "kunatsiridza wet friction resistance", "ink gloss and impermeability", "plastic", "folding resistance" uye "gloss yakavandudzwa", nezvimwewo.

Iyo yakakodzera lubricant inofanira kuratidza zvinotevera zvivakwa

(1) kuzora pendi uye kuvandudza kuyerera kwayo maitiro;

(2) Iva nechokwadi chekuputira zvakanaka;

(3) Kuvandudza kupenya kwechigadzirwa chakaputirwa;

(4) Kuvandudza kudhindwa kwepepa;

(5) Deredza kutsemuka uye kusvuuka kwekuputira kana bepa rapetwa;

(6) Deredza kana bvisa hupfu mune super calender.
