Hydroxyethyl cellulose (HEC) ke ether e seng ionic cellulose e entsoeng ka selulose ea tlhaho ea polymer ka letoto la etherification. Ke phofo e tšoeu e sa nkheng, e sa latsoeheng, e se nang chefo kapa granule, e ka qhibilihang metsing a batang ho etsa tharollo e hlakileng ea viscous, 'me ho qhibiliha ha ho amehe ke boleng ba pH. E na le ho tenya, ho tlama, ho qhalakanya, emulsifying, ho etsa filimi, ho emisa, ho bapatsa, ho sebetsa ka holim'a metsi, ho boloka mongobo le ho thibela letsoai. E sebelisoa haholo ho penta, kaho, masela, lik'hemik'hale tsa letsatsi le letsatsi, pampiri, ho cheka oli le liindasteri tse ling.
Libaka tsa kopo tse ka sehloohong
ho roala
Pente e entsoeng ka metsi ke mokelikeli oa viscous o entsoeng ka li-solvents kapa metsi a thehiloeng holim'a resin, kapa oli, kapa emulsion, ka ho eketsoa ha li-additives tse lumellanang. Liaparo tse entsoeng ka metsi tse nang le ts'ebetso e babatsehang le tsona li lokela ho ba le ts'ebetso e ntle ea ts'ebetso, matla a ho pata hantle, ho khomarela litlolo tse matla, le ts'ebetso e ntle ea ho boloka metsi; cellulose ether ke thepa e tala e loketseng ho fana ka thepa ena.
kaho
Lefapheng la indasteri ea kaho, HEC e sebelisoa e le tlatsetso ea lisebelisoa tse kang lisebelisoa tsa marako, konkreite (ho kenyeletsoa le asphalt), lithaele tse pentiloeng le lisebelisoa tsa ho caulking.
Li-additives li ka eketsa viscosity le ho teteana ha thepa ea mohaho, ho ntlafatsa ho khomarela, ho matlafatsa le ho boloka metsi, ho matlafatsa matla a likarolo kapa likarolo, ho ntlafatsa ho fokotseha, le ho qoba mapetsong a bohale.
Textile
K'hothone e entsoeng ka HEC, li-synthetic fibers kapa li-blends li ntlafatsa thepa ea tsona e kang abrasion resistance, dyeability, fire resistance le stain resistance, hammoho le ho ntlafatsa botsitso ba 'mele ea bona (shrinkage) le nako e telele, haholo-holo bakeng sa likhoele tsa maiketsetso, tse etsang hore li phefumolohe le ho fokotsa static. motlakase.
lik'hemik'hale tsa letsatsi le letsatsi
Cellulose ether ke tlatsetso ea bohlokoa lihlahisoa tsa letsatsi le letsatsi tsa lik'hemik'hale. E ke ke ea ntlafatsa feela viscosity ea litlolo tsa mokelikeli kapa emulsion, empa hape e ntlafatsa ho hasana le botsitso ba foam.
ho etsa pampiri
Lefapheng la ho etsa pampiri, HEC e ka sebelisoa e le sesebelisoa sa boholo, se matlafatsang le mofetoleli oa pampiri.
ho cheka oli
HEC e sebelisoa haholo-holo e le moemeli oa ho tiisa le ho tsitsisa ts'ebetsong ea phekolo ea oli. Ke k'hemik'hale e ntle ea sebaka sa oli. E ne e sebelisoa haholo ho cheka, ho phethela hantle, ho kenya samente le mesebetsing e meng ea tlhahiso ea oli linaheng tse ling lilemong tsa bo-1960.
Likarolo tse ling tsa kopo
temothuo
Hydroxyethyl cellulose (HEC) e ka khona ho emisa chefo e tiileng ka har'a li-sprays tse thehiloeng metsing.
HEC e ka bapala karolo ea ho khomarela chefo makhasi ka ts'ebetso ea ho fafatsa; HEC e ka sebelisoa e le setenya bakeng sa li-emulsion tsa spray ho fokotsa ho hoholeha ha lithethefatsi, ka hona ho eketsa ts'ebeliso ea ho fafatsa ka foliar.
HEC e ka boela ea sebelisoa e le moemeli oa ho etsa lifilimi ho lihlahisoa tsa ho roala peo; joalo ka sekhomaretsi ha ho sebelisoa mahlaku a koae.
mollo
Hydroxyethyl cellulose e ka sebelisoa e le tlatsetso ho eketsa ts'ebetso e koahelang ea thepa e sa cheng, 'me e sebelisitsoe haholo ho lokiseng "li-thickeners" tse sa cheng.
forging
Hydroxyethylcellulose e ka ntlafatsa matla a metsi le ho honyela ha lehlabathe la samente le litsamaiso tsa lehlabathe la sodium silicate.
Maekorosekopo
Hydroxyethyl cellulose e ka sebelisoa tlhahisong ea lifilimi le joalo ka dispersant tlhahiso ea li-slide tse nyane haholo.
Thickener ka maro a letsoai le phahameng a sebelisoang bakeng sa ho lokisa filimi.
pente ea fluorescent tube
E sebelisoa e le se tlamellang le dispersant e tsitsitseng bakeng sa lisebelisoa tsa fluorescent ka liphahlo tsa fluorescent tube.
Electroplating le Electrolysis
E ka sireletsa colloid ho tloha tšusumetsong ea mahloriso a electrolyte; hydroxyethyl cellulose e ka khothaletsa ho beoa ho tšoanang ka tharollo ea cadmium plating.
li-ceramics
E ka sebelisoa ho etsa li-binders tse matla haholo bakeng sa lirafshoa.
