Mokhoa oa ho sebelisa hydroxyethyl cellulose HEC ka metsingpenta
1. Eketsa ka ho toba ha u sila pigment: mokhoa ona ke o bonolo ka ho fetisisa, 'me nako e sebelisoang e khutšoanyane. Mehato e qaqileng ke e latelang:
(1) Eketsa metsi a hloekisitsoeng a loketseng ka har'a VAT ea moferefere o phahameng oa ho itšeha (ka kakaretso, ethylene glycol, moemeli oa ho kolobisa le mochine oa ho etsa lifilimi li eketsoa ka nako ena)
(2) Qala ho sisinyeha ka lebelo le tlaase 'me butle-butle eketsa hydroxyethyl cellulose
(3) Tsoela pele ho sisinya ho fihlela likaroloana tsohle li kolobile
