3.Hydroxyethyl Cellulose (HEC) Likopo:
Ka pente e thehiloeng metsing, e bapala karolo ea ho qhalakanya le ho sireletsa li-gel, ho matlafatsa botsitso ba karabelo ea tsamaiso ea agglomerate, ho netefatsa kabo e ts'oanang ea pigment le stuffing, le ho fana ka phello ea ho teteaneng, ho ntlafatsa metsi.
Ha ho cheka oli, e sebelisoa e le stabilizer le thickening agent, lubricating agent bakeng sa ho cheka seliba, ho tlatsa le ho kopanya ho fana ka slurry mokelikeli o motle le botsitso.
Ha ho hahoa, HEC e ka sebelisoa e le moemeli oa motenya le moemeli ea momahaneng ho ntlafatsa metsi le ho sebetsa, ho eketsa matla a pele a gelling le ho qoba ho phatloha.
Ho borashe le ho kopanya plaster, ho hlakile hore e ka phahamisa matla a ho tšoara metsi le momahano.
Lik'hemik'haleng tse sebelisoang letsatsi le leng le le leng joalo ka sesepa sa meno se fana ka thepa e ntle ea 'mele le ea lik'hemik'hale, e etsa hore e be ntle ka sebopeho, nako e telele ea polokelo, e omelle ebile e kenelletse.
Sebakeng sa litlolo, e ka eketsa bongata ba lintho tse bonahalang, ea eketsa lubrication le boreleli.
Ntle le moo, e na le ts'ebeliso e pharaletseng ho enke, ho daea masela & khatiso, ho etsa pampiri, meriana, lijo, temo joalo-joalo.
4.Hydroxyethyl Cellulose (HEC) Ho sebelisa mokhoa :
Mokhoa oa pele: Kenya ka ho toba
1. Tšela metsi a hloekileng ka har'a bakete e nang le sekontiri.
2. Ha u qala, hlohlelletsa butle butle, u hasanye HEC ka har'a tharollo.
3. Hlohlelletsa ho fihlela granule tsohle tsa HEC li kolobile ka ho feletseng.
4. Qala ka ho kenya anti-mildew agent, ebe u eketsa li-additives tse kang pigment, disperser joalo-joalo.
5. Tsoela pele ho sisinyeha ho fihlela HEC eohle le li-additives li qhibiliha ka ho feletseng (viscosity ka tharollo e ntse e eketseha), ebe u kenya lisebelisoa tse ling ho arabela.
Mokhoa oa Bobeli: Lokisetsa Joala ba 'Mè bakeng sa Tšebeliso
Pele lokisa joala bo botenya ba 'm'e, ebe o bo kenya sehlahisoa.Molemo oa mokhoa ke ho feto-fetoha ha maemo, joala bo ka kenngoa ka ho toba sehlahisoa.Mokhoa le mokhoa oa ho o sebelisa o tšoana le 1-4 ka mokhoa(Ⅰ), be hlohlelletsa ka ho feletseng ho fihlela e qhibiliha ka ho feletseng ka motsoako o khomarelang le o motenya, 'me u tšele moriana o thibelang hlobo ka har'a joala ba 'mè kapele kamoo ho ka khonehang.
Mokhoa oa Boraro: Lokisetsa Lintho tse kang Gruel bakeng sa Tšebeliso
Kaha li-solvents tsa organic ha li na li-solvents bakeng sa HEC, li ka sebelisoa ho lokisa lintho tse kang gruel. Tse sebelisoang haholo ke ethylene glycol, propylene glycol le filimi-forming agent (hexamethylene-glycol, diethyl glycol butyl acetate joalo-joalo) metsi, e ka boela ea lokisoa hammoho le li-solvents tsa tlhaho hore e be lintho tse kang gruel.
Lintho tse kang Gruel li ka kenngoa sehlahisoa hobane HEC ka thepa e kang gruel e kolobisitsoe ka ho feletseng 'me e ruruhile, e kenngoa sehlahisoa e qhibiliha hang-hang 'me e khothalletsa ho teteaneng, empa u tsoele pele ho hlohlelletsa ho fihlela e qhibiliha ka ho feletseng.
Hangata ntho e kang gruel e fumanoa ka ho kopanya motsoako oa motsoako kapa metsi a leqhoa le HEC ka karolo ea 6: 1, ka mor'a metsotso e 5-30 HEC e hlahisa metsi 'me haholo-holo e ruruha.
5. Tataiso ea Kopo ea Liindasteri Tsa Penta
High Thickening Liphello
Hydroxyethy Cellulose e fana ka lipente tsa latex haholo-holo lipente tse phahameng tsa PVA tse nang le ts'ebetso e ntle ea ho roala.Ha pente e le pente e teteaneng, ha ho na flocculation e tla etsahala.
Hydroxyethy Cellulose e na le litlamorao tse phahameng tsa ho tenya, ka hona e ka fokotsa litekanyetso, ea ntlafatsa ts'ebetso e ntle ea litšenyehelo tsa ho etsa lipente, 'me ea ntlafatsa ho hanyetsa ho hlatsuoa ha lipente.
Thepa e Ntle ea Rheological
Tharollo ea metsi a Hydroxyethy Cellulose ke tsamaiso e seng ea Newtonian, 'me thepa ea tharollo e bitsoa thixotropy.
Sebakeng se emeng, ka mor'a hore sehlahisoa se qhibilihe ka ho feletseng, mokhoa oa ho roala o ka boloka boemo bo botle ka ho fetisisa bo boima le boemo ba ho bula.
Boemong ba ho lahla, tsamaiso e ka boloka viscosity e itekanetseng, e etsa lihlahisoa tse nang le mokelikeli o babatsehang, 'me li se ke tsa fafatsa.
Nakong ea ho roala le ho roala, sehlahisoa se bonolo ho jala holim'a substrate, kahoo se loketse ho haha, 'me ho sa le joalo, se na le khanyetso e ntle ea spatter.
Qetellong, ka mor'a hore pente e phethoe, viscosity ea tsamaiso e tla tsosolosoa hang-hang, 'me pente e tla hlahisa thepa e sagging hang-hang.
Phatlalatso le Solubility
Hydroxyethy Cellulose kaofela e phekoloa ka ho lieha ho qhibiliha, 'me tabeng ea ho eketsa phofo e omeletseng, e ka thibela ka katleho ho thibela ho baka le ho etsa bonnete ba hore hydration e qala ka mor'a ho qhalakanngoa ho lekaneng ha HEC phofo.
Hydroxyethy Cellulose ka mor'a phekolo e nepahetseng ea holim'a metsi e ka laola hantle sekhahla sa ho qhibiliha le sekhahla sa ho eketseha ha viscosity ea sehlahisoa.
Botsitso ba polokelo
Hydroxyethy Cellulose e na le ts'ebetso e ntle e mamellang hlobo, e fana ka nako e lekaneng ea ho boloka lipente, 'me e thibela ka katleho ho lula ha mebala le li-fillers.a
