Pente grade CMC
Pente grade CMC Sodium carboxymethyl cellulose ke lik'hemik'hale fetotsoeng ka sebopeho ether ea derivatives selulose, ka bobeli ba le thickening, ho boloka metsi, bonding, ho fanyeha botsitso, emulsifying qhalahano, tšireletso ea colloid le properties.CMC tse ling li na le thickening e ntle, disperity le botsitso, e ka ntlafatsa. li-viscosity le rheology ea ho roala, kahoo e sebelisoa haholo ka liphahlo tse fapa-fapaneng, liphahlo tsa latex, tse nang le metsi a ka ntle le a ka hare, liaparo tsa ho roala joalo-joalo.
Paint grade CMC E ka sebelisoa e le anti-sinking agent, emulsifier, dispersant, leveling agent, sekgomaretsi, e ka etsa hore karolo e tiileng ea ho roala e aroloe ka mokhoa o ts'oanelang ho solvent, e le hore seaparo se se ke sa stratified nako e telele.
Likaroloana:
Paint grade CMC e ka sebelisoa e le stabilizer ho thibela karohano ea pente ka lebaka la liphetoho tse potlakileng tsa mocheso
Joalo ka moemeli oa viscosity, Paint grade CMC e ka etsa junifomo ea naha ea pente, ea fihlela polokeho e ntle le viscosity ea kaho, mme ea thibela ho senyeha ho hoholo nakong ea polokelo.
Paint grade CMC e ka thibela ho rotha le ho fanyeha.
Tharollo ea CMC e na le pepenene e ntle le likaroloana tse nyane tsa gel.

1. CMC e sebelisitsoeka ho qoela
CMC polymer motsoako, multistranded, ka mor'a hore metsi ho ruruha otlolohileng-ketane bulehileng le interactive foromo letlootlo otlolla, colloid, ka sodium botlaaseng bentonite le tshebedisano ya lona, eseng feela ka ntlafatsa bokgoni ba sodium base bentonite fanyeha, 'me ka haholo fokotsa precipitation agglomerate bophahamo ba modumo. , ka nako e ts'oanang thibela phofshoana ea refractory ho teba, ka hona e atisa ho sebelisoa ho eketsa tekanyo ea ho emisa ho roala ho lahla, Ka nako e ts'oanang ho ntlafatsa viscosity ea pente:
* Ho qhibiliha ha metsi ka mokhoa o babatsehang le viscosity, ka katleho ho ntlafatsa viscosity ea ho roala le rheology
* Good solubility le hasana, e le hore lintho tse bonahalang tiileng fanyehiloe ka mokelikeli mokelikeli
* Khothaletsa ho emisoa ha phofo ea refractory ho thibela pula, stratification le ho kenella ho feteletseng ha mokelikeli oa mokelikeli ka har'a thepa ea ho bopa.
* Ntlafatsa bokhoni ba ho roala le ho koahela, ho ntlafatsa borashe le boemo ba ho roala
* Phofo ka ho roala e tlamahane ka mor'a ho omisa, 'me e khomaretsoe ka thata holim'a mofuta le motheo.
2. CMC e sebelisitsoepente e tloaelehileng
CMC e nang le hydroxyl macromolecular chain hydration ka metsi, ha e ntse e phalla, kahoo e eketsa viscosity ea mohato oa metsi, ka metsing kapa li-solvents li na le tumellano e ntle, 'me ho lumellana ha pigment ho boetse ho molemo,' me ho ka ntlafatsa haholo viscosity le rheology ea pente, ka Indasteri ea pente e atisang ho sebelisoa e le ntho e teteaneng, dispersant le stabilizer, Litlamorao tse khethehileng tsa CMC ts'ebetsong ea liphahlo tse qhibilihang ka metsi ke tse latelang:
* Ho hanyetsa metsi hantle le ho tšoarella ha filimi ea ho roala
* Filimi e felletseng, filimi e ts'oanang, e ka fumana lintlha tsa bohlokoa
* Joaloka stabilizer, thibela karohano ea ho roala ka lebaka la liphetoho tse potlakileng tsa mocheso;
* Joaloka colloid e sireletsang, e ka boloka botsitso ba mekhoa ea ho roala ka mefuta e mengata ea pH ea boleng
* Joalo ka ha motenya o ka etsa junifomo ea ho roala, ho fihlela polokeho e nepahetseng le viscosity ea kaho, qoba stratification e tebileng nakong ea polokelo.
* Ntlafatsa boemo ba ho roala, ntlafatsa ts'ebetso ea ho thibela ho phatloha, ho hanyetsa phallo, e le ho ntlafatsa ts'ebetso ea kaho ea ho roala.
* E ka etsa hore pigment, filler le li-additives tse ling li hasane ka mokhoa o ts'oanang ka har'a seaparo, e le hore seaparo se be le phello e ntle ea ho kopanya mebala.
3. CMC e sebelisoa ka latexpenta
Ho roala ha polymer latex haholo-holo ho entsoe ka mokhoa oa metsi le ho penta sebopeho se itseng, li-viscosity tsa eona li penta sebakeng sa subsidence, besmear ho borashe, rolara le botlalo ba lera, le thepa e phallang ka lera holim'a phello ea phallo e otlolohileng e fanyehiloe. hangata ho hloka viscosity le thepa ea rheological ea liphahlo tsa latex e ka fetoloa, 'me CMC e na le mokelikeli o motle, ho hanyetsa borashe ba pente ea latex e nyane, Ho bonolo ho e haha le ho sebelisoa e le stabilizer, thickener le moemeli oa ho boloka metsi bakeng sa liphahlo tsa latex:
* Phello e ntle haholo ea ho tenya, ts'ebetso e phahameng ea ho tenya ha latex
* Ka etsa barbotage le itseng viscosity, ka polokelo ha precipitate, le botsitso
* E ka thibela metsi ho kena ka potlako substrate ea porous, e le hore litaba tse phahameng tsa emulsion li ka finyella litlhoko tsa ho boloka metsi.
* Lithibelo tse fokolang mabapi le foromo ea ho roala, e sa ameheng haholo ke mofuta oa latex, li-disperants le li-surfactants
* Ha ho roala ho felile, tšenyo ea motsoako oa metsi pakeng tsa CMC le metsi e felisoa, 'me viscosity e tsosolosoa ho thibela phallo e leketlileng.
