Tšebeliso ea mantlha ea carboxymethyl cellulose ke efe

Tšebeliso ea carboxymethyl cellulose ke cellulose ether e nang le thepa e ntle ka ho fetisisa ea 'mele le ea lik'hemik'hale' me e sebelisoa ka ho fetisisa indastering ea cellulose ether, 'me tšebeliso ea carboxymethyl cellulose ke ea li-non-ionic cellulose ethers. Hobane HPMC e na le thepa e ntle haholo joalo ka ho tenya, emulsification, ho etsa filimi, colloid e sireletsang, ho boloka mongobo, ho khomarela, ho hanyetsa enzyme le ho se sebetse ha metabolism, carboxymethyl cellulose e sebelisoa haholo kahong, liphahlo tsa latex, meriana, polychlorinated Ethylene, lik'hemik'hale tsa letsatsi le letsatsi, li-ceramics le temo. tlhahiso.

Tšebeliso ea carboxymethyl cellulose Ka indasteri ea kaho le thepa ea mohaho, mosebetsi o ka sehloohong oa HPMC ke ho eketsa viscosity, ho teteaneng, ho boloka metsi, ho tlotsa, ho ntlafatsa ts'ebetso le ho pompa ha samente le gypsum; tšebeliso ea carboxymethyl cellulose ho latex Coatings e sebelisoa haholo-holo e le li-colloids tse sireletsang, li-thickeners le li-pigment suspending agents; tšebeliso ea carboxymethyl cellulose indastering ea meriana e sebelisoa haholo-holo bakeng sa tlhahiso ea litokisetso, e le ho roala letlapa le ho etsa li-binders, 'me e ka sebelisoa bakeng sa tokollo e tsitsitseng Tlhahiso ea meriana; tšebeliso ea carboxymethyl cellulose e sebelisoa haholo-holo lisebelisoa tsa ho itšireletsa ka lik'hemik'hale tsa letsatsi le letsatsi, 'me tšebeliso ea carboxymethyl cellulose e ka ntlafatsa emulsification, anti-enzyme, dispersion, adhesion, mosebetsi oa holim'a metsi, filimi-forming, Moisturizing, foaming le thepa e meng; carboxymethyl cellulose e boetse e sebelisoa tlhahisong ea polyvinyl chloride, haholo-holo e sebelisoang e le dispersant karabelong ea polymerization ea sisteme ea ho emisa polymerization, 'me hajoale e na le mefuta e mengata ea tlhahiso ts'ebelisong ea lefats'e ea tlhahiso ea polyvinyl chloride. Ho phaella moo, tšebeliso ea carboxymethyl cellulose e boetse e sebelisoa e le moemeli oa tlamahano bakeng sa likheo tsa indasteri ea ceramic le dispersant bakeng sa glaze; temong, carboxymethyl cellulose e sebelisoa ho phekola peo ea lijalo, e ka eketsang lebelo la ho mela, e ke keng ea kolobisa feela empa hape e sireletsa letlalo. E ka thibela hlobo joalo-joalo.

Kenyelletso ea tšebeliso ea carboxymethyl cellulose:

Tšebeliso ea carboxymethyl cellulose ke ether e seng ea ionic cellulose e entsoeng ka thepa ea tlhaho ea polymer e hloekisitsoeng ka letoto la ts'ebetso ea lik'hemik'hale. Ponahalo ea carboxymethyl cellulose ke phofo e tšoeu, ha e na chefo, ha e na tatso ebile ha e na monko. E ka qhibiliha ka metsing a batang ho etsa colloid e hlakileng ea viscous.

  1. Tšebeliso ea carboxymethyl cellulose e na le ts'ebetso e ntle haholo ea ho boloka metsi. Esita le haeba seretse se nang le carboxymethyl cellulose se sebelisoa ho substrate e nang le metsi haholo, e ka boloka ts'ebetso ea ts'ebetso ea seretse nako e telele, 'me tšebeliso ea carboxymethyl cellulose e lumellana le li-surfactants tse ngata le li-polymers tse thehiloeng metsing. Tšebeliso ea carboxymethyl cellulose e ka lelefatsa nako ea ho bula seretse sa samente, ea ntlafatsa katleho ea mosebetsi, ea ntlafatsa shrinkage le ho hanyetsa ho phatloha, le ho ntlafatsa boleng ba holim'a metsi.
  2. Tšebeliso ea carboxymethyl cellulose Likaroloana li batla li le ntle, ka kakaretso li fihla ho li-meshes tse 120, tse leng bonolo haholoanyane ho kopanya le seretse sa samente, gypsum, lime le lisebelisoa tse ling, e le hore metsoako ena e se ke ea e-ba bonolo ho e kopanya ha e hasane ka metsing.
  3. Carboxymethyl cellulose e ka sebelisoa ka har'a seretse sa samente, sistimi ea ho kenya mocheso e kantle ea lebota le lihlahisoa tse ts'oanang, haholoholo bakeng sa sistimi ea kantle ea mocheso oa lerako.
  4. Tšebeliso ea carboxymethyl cellulose e na le lubricity e ntle, 'me thepa ka mor'a ho sebelisa hydroxypropyl methyl cellulose (HPMC) e ka ntlafatsa haholo ts'ebetso ea lisebelisoa, ho etsa hore ho be bonolo ho sebelisa trowel le ho ntlafatsa bokhoni ba Anti-sliding ea seretse.
  5. Tšebeliso ea carboxymethyl cellulose e ka matlafatsa matla a kopantsoeng, ea thusa seretse ho theha matla a phahameng a mochine nakong ea ho beha, le ho ntlafatsa matla a ho kopanya le matla a ho kuta a seretse.
