Lintho tse ka sehloohong tsa hydroxyethyl cellulose ke hore e qhibiliha metsing a batang le metsing a chesang, 'me ha e na thepa ea gelling. E na le mefuta e mengata e fapaneng ea degree ea substitution, solubility le viscosity. pula. Tharollo ea selulose ea Hydroxyethyl e ka etsa filimi e hlakileng, 'me e na le litšobotsi tsa mofuta o seng oa ionic o sa sebelisaneng le li-ion le ho lumellana hantle.
①Mocheso o phahameng le ho qhibiliha ha metsi: Ha ho bapisoa le methyl cellulose (MC), e qhibilihang feela metsing a batang, hydroxyethyl cellulose e ka qhibiliha ka metsing a chesang kapa a batang. Mefuta e mengata ea solubility le viscosity properties, le gelation e seng ea mocheso.
②Ho hanyetsa letsoai: Ka lebaka la mofuta oa eona o seng oa ionic, o ka phela hammoho le li-polymers tse ling tse qhibilihang ka metsing, li-surfactants le letsoai ka bongata. Ka hona, ha e bapisoa le ionic carboxymethyl cellulose (CMC), hydroxyethyl cellulose e na le khanyetso e ntle ea letsoai.
③ Ho boloka metsi, ho leka-lekanya, ho etsa filimi: matla a eona a ho boloka metsi a imenne habeli ho feta methyl cellulose, e nang le taolo e ntle ea phallo le ho etsa filimi e ntle haholo, phokotso ea tahlehelo ea mokelikeli, miscibility, thobalano e sireletsang ea colloid.
Tšebeliso ea hydroxyethyl cellulose
Hydroxyethyl cellulose ke sehlahisoa sa ether se se nang ionic se nang le metsi a selulose, se sebelisoang haholo ka liphahlo tsa meralo, peterole, polymerization ea polymer, meriana, tšebeliso ea letsatsi le letsatsi, pampiri le enke, masela, ceramics, kaho, temo le liindasteri tse ling. E na le mesebetsi ea ho tiisa, ho kopanya, ho emulsifying, ho qhalakanya le ho tsitsisa, 'me e ka boloka metsi, ho etsa filimi le ho fana ka phello e sireletsang ea colloid. E qhibiliha habonolo metsing a batang le metsing a chesang, 'me e ka fana ka tharollo ka mefuta e mengata ea viscosity. E 'ngoe ea li-ether tsa cellulose tse potlakileng.
1 pente ea latex
Hydroxyethyl cellulose ke setenya se sebelisoang haholo liphahlong tsa latex. Ntle le ho tiisa liphahlo tsa latex, e ka boela ea emulsify, ea qhalakanya, ea tsitsisa le ho boloka metsi. E khetholloa ka phello e tsotehang e teteaneng, nts'etsopele e ntle ea mebala, thepa ea ho etsa filimi le botsitso ba polokelo. Hydroxyethyl cellulose ke ntho e tsoang ho selulose e seng ea ionic e ka sebelisoang maemong a mangata a pH. E na le tumellano e ntle le lisebelisoa tse ling tse ka har'a motsoako (joalo ka li-pigments, li-additives, li-fillers le letsoai). Liaparo tse teteaneng ka hydroxyethyl cellulose li na le rheology e ntle ka litekanyetso tse fapaneng tsa ho kuta 'me ke pseudoplastic. Ho ka sebelisoa mekhoa ea kaho e kang ho hlapa, ho roala lirolara le ho fafatsa. Mohaho o motle, ha ho bonolo ho rotha, ho thella le ho fafatsa, le boemo bo botle.
2 Polymerization
Hydroxyethyl cellulose e na le mesebetsi ea ho hasanya, emulsifying, ho emisa le ho tsitsisa likarolong tsa polymerization kapa copolymerization ea li-resin tsa maiketsetso, 'me e ka sebelisoa e le colloid e sireletsang. E khetholloa ke bokhoni bo matla ba ho qhalakanngoa, "filimi" e tšesaane ea likaroloana, boholo bo botle ba likaroloana, sebōpeho sa likaroloana tse ts'oanang, mofuta o hlephileng, metsi a matle, pepeneneng e phahameng ea lihlahisoa le ho sebetsa habonolo. Hobane cellulose ea hydroxyethyl e ka qhibiliha ka metsing a batang le metsing a chesang, 'me ha e na mocheso oa mocheso, e loketse karabelo e fapaneng ea polymerization.
Lintho tsa bohlokoa tsa 'mele ho batlisisa boleng ba dispersant ke tsitsipano ea holim'a (kapa sefahleho), matla a sefahleho le mocheso oa gelation oa tharollo ea eona ea metsi. Lintho tsena tsa hydroxyethyl cellulose li loketse polymerization kapa copolymerization ea li-resin tsa maiketsetso.
Hydroxyethyl cellulose e lumellana hantle le tse ling tse qhibilihang ka metsing cellulose ethers le PVA. Tsamaiso e kopaneng e entsoeng e ka fumana phello e felletseng ea ho ithuta ho tsoa ho matla a e mong le ho tlatsana le mefokolo ea motho. Lihlahisoa tse entsoeng ka resin ha li na boleng bo botle feela, empa hape li fokotsa tahlehelo ea thepa.
3 ho cheka oli
Ha ho cheka oli le tlhahisong, hydroxyethyl cellulose e nang le viscosity e phahameng e sebelisoa haholo-holo joalo ka viscosifier bakeng sa ho tlatsa maro le maro a ho qetela. Low viscosity hydroxyethyl cellulose e sebelisoa e le se fokotsang tahlehelo ea mokelikeli. Lirapeng tse fapa-fapaneng tse hlokahalang bakeng sa ho cheka, ho phethoa, ho etsa samente le ho senya, hydroxyethyl cellulose e sebelisoa e le motenya ho fumana metsi a matle le botsitso ba seretse. Nakong ea ho cheka, e ka ntlafatsa bokhoni ba ho jara lehlabathe la seretse le ho lelefatsa bophelo ba tšebeletso ea karolo ea ho phunya. Mekelikeli ea ho phethoa ha mekhahlelo e tlaase le maro a samente, thepa e babatsehang ea ho fokotsa tahlehelo ea metsi ea hydroxyethyl cellulose e ka thibela metsi a mangata ho kena lera la oli ho tloha seretseng, 'me e ka ntlafatsa bokhoni ba tlhahiso ea lera la oli.
4 K'hemik'hale ea letsatsi le letsatsi
Hydroxyethylcellulose ke filimi e sebetsang ea pele, binder, thickener, stabilizer le dispersant ka shampoos, spray sprays, neutralizers, conditioners le cosmetics; ka li-detergent powders Ke moemeli oa ho khutlisetsa litšila. Hydroxyethyl cellulose e qhibiliha ka potlako mocheso o phahameng, o ka potlakisang ts'ebetso ea tlhahiso le ho ntlafatsa katleho ea tlhahiso. Ntho e totobetseng ea li-detergents tse nang le hydroxyethyl cellulose ke hore e ka ntlafatsa boreleli le mercerization ea masela.
5 meralo ea kaho
Hydroxyethyl cellulose e ka sebelisoa lihlahisoa tsa kaho tse kang metsoako ea konkreite, seretse se secha, samente ea gypsum kapa lirafshoa tse ling, joalo-joalo, ho boloka metsi nakong ea kaho pele a beha le ho thatafala. Ntle le ho ntlafatsa ho boloka metsi a lihlahisoa tsa mohaho, hydroxyethyl cellulose e ka boela ea lelefatsa khalemelo le nako e bulehileng ea stucco kapa mastic. E fokotsa ho fokola ha letlalo, ho thella le ho thella. Sena se ka ntlafatsa ts'ebetso ea kaho, sa ntlafatsa ts'ebetso ea ts'ebetso, sa boloka nako, 'me ka nako e ts'oanang sa eketsa sekhahla sa katoloso ea molumo oa stucco, ka hona ho boloka thepa e tala.
6 temo
Hydroxyethyl cellulose e sebelisoa ho emulsion ea chefo e bolaeang likokonyana le ho fanyeha ho fanyeha e le motenya bakeng sa li-emulsions tsa spray kapa suspensions. E ka fokotsa ho hoholeha ha moemeli 'me ea etsa hore e khomarele ka thata makhasi a semela, kahoo e eketsa phello ea ho fafatsa ka foliar. Hydroxyethyl cellulose e ka boela ea sebelisoa e le moemeli oa ho etsa filimi ka ho roala peo le ho roala; joalo ka setlamo le ho etsa lifilimi ho nchafatsa makhasi a koae.
7 Pampiri le Enke
Hydroxyethyl cellulose e ka sebelisoa e le sesebelisoa sa boholo pampiring le botong hape e le ntho e tenya le e emisang bakeng sa li-inks tse thehiloeng metsing. Ts'ebetsong ea ho etsa pampiri, thepa e phahameng ea hydroxyethyl cellulose e kenyelletsa ho lumellana le marenene a mangata, li-resin le matsoai a sa tloaelehang, ho foaming ho fokolang, tšebeliso e tlaase ea oksijene le bokhoni ba ho etsa filimi e boreleli ea holim'a metsi. Filimi e na le "permeability" e tlase le khanya e matla, hape e ka fokotsa litšenyehelo. Pampiri e boholo bo nang le hydroxyethyl cellulose bakeng sa likhatiso tsa boleng bo holimo. Ha ho etsoa enke e thehiloeng metsing, enke e thehiloeng metsing e teteaneng ka hydroxyethyl cellulose e omella kapele, e na le phallo e ntle ea mebala, 'me ha e hlahise ho khomarela.
