Inokwakheka kwefilimu elungileyo, phucula i-gloss yokwambathisa;
Ukuphucula izinga lokugcinwa kwe-ejenti emhlophe kwi-coating, ukuphucula ubumhlophe bephepha;
Ukuphucula ukusebenza kwe-lubrication ye-coating, ukuphucula umgangatho wokugcoba, ukwandisa ubomi benkonzo ye-scraper.
2. Yongeza kwi-slurry
Ukuphucula ukusebenza kakuhle kokusila, ukukhuthaza ukulungiswa kwefayibha, ukunciphisa ixesha lokubetha;
Lungisa amandla ombane ngaphakathi kwi-pulp, ukusabalalisa ngokulinganayo i-fiber, uphucule "intsebenzo yokukopa" yomshini wephepha, kwaye uphucule ngakumbi ukwenza iphepha;
Ukuphucula ukugcinwa kwezongezo ezahlukeneyo, iifayili kunye nemicu emihle;
Ukwandisa amandla okubopha phakathi kweefayili, ukuphucula iimpawu ezibonakalayo zephepha;
Amandla omileyo namanzi ephepha anokuphuculwa xa esetyenziswa kunye ne-arhente yamandla eyomileyo nemanzi.
Khusela i-rosin, i-AKD kunye nezinye ii-ejenti zokulinganisa, phucula umphumo wokulinganisa.
3. Ubungakanani bomphezulu
Inepropathi elungileyo yerheological kunye nepropathi yokwenza ifilimu.
Ukunciphisa ama-pores ebusweni bephepha, ukuphucula ukuchasana kweoli kwephepha;
Ukwandisa ukukhanya kunye neglosi yephepha;
Ukwandisa ukuqina kwephepha, ukugudisa, ukulawula i-crimp;
Ukwandisa amandla angaphezulu kunye nokuxhatshazwa kwephepha, ukunciphisa ukuchithwa kweenwele kunye nomgubo, ukuphucula umgangatho wokushicilela.

Isicelo
Kwishishini lephepha, i-CMC isetyenziswa kwinkqubo yokucofa, enokuphucula izinga lokugcinwa kunye nokwandisa amandla amanzi. Isetyenziselwa ukulinganisa umphezulu, njenge-pigment excipient, ukuphucula ukunamathela kwangaphakathi, ukunciphisa uthuli lokuprinta, ukuphucula umgangatho wokushicilela; Isetyenziselwa ukugquma ngephepha, inceda ukusasazwa kunye nokunyibilika kwe-pigment, iphucula ukuguda kwephepha, ukuguda, iipropathi zamehlo kunye nokuguquguquka kokushicilela. Kwishishini lephepha njengexabiso elisebenzayo kunye noluhlu olubanzi lwezongezo, ngokukodwa ngenxa yokubunjwa kwefilimu ye-polymer ene-soluble yamanzi kunye nokumelana neoli.
● Isetyenziselwa ukwenza ubungakanani bephepha, ukwenzela ukuba iphepha libe noxinano oluphezulu, ukuxhathisa okulungileyo kwe-inki, ukuqokelelwa kwe-wax ephezulu kunye nokuguda.
● Unokuphucula imeko ye-fiber viscosity yangaphakathi yephepha, ukuze kuphuculwe amandla ephepha kunye nokuxhathisa ukusonga.
● Kwinkqubo yombala wephepha nephepha, i-CMC inceda ukulawula ukuhamba kombala wokuncamathisela kunye nokufunxa kakuhle kwe-inki.
Ngokuqhelekileyo, umthamo onconywayo ngu-0.3-1.5%.
Ukupakishwa:
IMveliso ye-CMC ipakishwe kwibhegi yephepha yomaleko emithathu ene-polyethylene yangaphakathi eqinisiwe, ubunzima bomnatha ngama-25kg ingxowa nganye.
