Mesebetsi ea Sodium Carboxymethyl cellulose ka ho Coating Pigment

Sodium carboxymethyl cellulose (CMC) e sebelisoa haholo mekhoeng ea ho roala ka pigment bakeng sa merero e fapaneng ka lebaka la thepa ea eona e ikhethang. Mona ke tse ling tsa mesebetsi ea bohlokoa ea sodium carboxymethyl cellulose ho roala pigment:

1. Binder: CMC e sebetsa e le tlamahano ea li-pigment coating formulations, e thusang ho khomarela likaroloana tsa pigment ka holim'a substrate, joalo ka pampiri kapa khateboto. E etsa filimi e feto-fetohang le e momahaneng e kopanyang likaroloana tsa pigment hammoho le ho li kopanya ho substrate, ho ntlafatsa ho khomarela le ho tšoarella ha seaparo.
2. Thickener: CMC e sebetsa e le ntho e tenya mefuteng ea li-pigment coating, e eketsang viscosity ea motsoako oa ho roala. Viscosity ena e ntlafalitsoeng e thusa ho laola ho phalla le ho hasana ha thepa ea ho roala nakong ea kopo, ho netefatsa tšireletso e tšoanang le ho thibela ho theoha kapa ho rotha.
3. Stabilizer: CMC e tsitsisa li-dispersions tsa pigment mefuteng ea ho roala ka ho thibela ho kopana ha likaroloana le sedimentation. E etsa colloid e sireletsang ho pota-potile likaroloana tsa pigment, e li thibelang ho tsoa ka ntle ho ho emisoa le ho etsa bonnete ba hore ho ajoa ka mokhoa o ts'oanang ho pholletsa le motsoako oa ho roala.
4. Rheology Modifier: CMC e sebetsa joalo ka mofetoleli oa rheology mekhoeng ea ho roala ka pigment, e susumetsang phallo le litšoaneleho tsa boemo ba thepa ea ho roala. E thusa ho ntlafatsa thepa ea phallo ea ho roala, e lumella ho boreleli le ho sebetsa ho substrate. Ntle le moo, CMC e ntlafatsa bokhoni ba ho roala ba ho lekanya bofokoli le ho etsa sephetho se tšoanang sa bokaholimo.
5. Moemeli oa ho Boloka Metsi: CMC e sebetsa e le moemeli oa ho boloka metsi mekhoeng ea ho roala ha 'mala, e thusang ho laola sekhahla sa ho omisa ha thepa ea ho roala. E monya le ho tšoara limolek'hule tsa metsi, e liehisa ts'ebetso ea mouoane le ho lelefatsa nako ea ho omisa ea ho roala. Nako ena ea nako e telele ea ho omisa e lumella boemo bo betere le ho fokotsa kotsi ea likoli tse kang ho petsoha kapa ho phatloha.
6. Surface Tension Modifier: CMC e fetola tsitsipano ea bokaholimo ba litlolo tsa pigment, e ntlafatsa ho kolobisa le ho hasana. E fokotsa tsitsipano ea holim'a thepa ea ho roala, e lumella hore e hasane ka mokhoa o ts'oanang holim'a substrate le ho khomarela hantle holimo.
7. pH Stabilizer: CMC e thusa ho tsitsisa pH ea libotlolo tsa pigment coating, e sebetsa joalo ka ntho e thibelang ho boloka pH e batloang. E thusa ho thibela ho fetoha ha pH ho ka amang botsitso le ts'ebetso ea thepa ea ho roala.

sodium carboxymethyl cellulose e bapala karolo ea bohlokoa mekhoeng ea ho roala ha pigment ka ho sebetsa e le se tlamellang, se teteaneng, se tsitsitseng, se feto-fetohang sa rheology, se bolokang metsi, se fetolang khatello ea holim'a metsi, le pH stabilizer. Mehaho ea eona e nang le mesebetsi e mengata e kenya letsoho ho ntlafatseng ho khomarela ha li-coat, ho tšoana, ho tšoarella, le boleng ba kakaretso ba sehlahisoa se felileng.
