Hydroxyethyl cellulose (HEC)ke non-ionic cellulose ether entsoe ho tloha tlhaho polymer thepa selulose 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 ts'ebeliso ea mantlha:
1.Paint: Pente e thehiloeng metsing ke mokelikeli oa viscous o entsoeng ka metsoako ea lintho tse phelang kapa metsi a thehiloeng ho resin, kapa oli, kapa emulsion, hammoho le tlatsetso ea 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.
2.Kaho: Lefapheng la indasteri ea kaho, HEC e sebelisoa e le tlatsetso bakeng sa lisebelisoa tse kang lisebelisoa tsa marako, konkreite (ho kenyeletsoa le asphalt), lithaele tse pentiloeng le lisebelisoa tsa caulking, tse ka eketsang viscosity le motenya oa thepa ea mohaho, ho ntlafatsa ho khomarela, lubricity, le ho boloka metsi. Ntlafatsa matla a flexural a likarolo kapa likarolo, ntlafatsa ho honyela, 'me u qobe mapetso a mathoko.
3.Textile: k'hothone e entsoeng ka HEC, likhoele tsa maiketsetso kapa metsoako e ntlafatsa thepa ea bona e kang ho hanyetsa abrasion, dyeability, ho hanyetsa mollo le ho hanyetsa matheba, 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 motlakase o tsitsitseng.
4.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.
5.Paper: Lefapheng la ho etsa pampiri, HEC e ka sebelisoa e le moemeli oa boholo, e matlafatsang le mofetoleli oa pampiri.
6. Ho cheka oli: HEC e sebelisoa haholo-holo e le ntho e tiisang 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:
HECe 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 setlamo sa ho sebelisoa ha makhasi a koae. Hydroxyethyl cellulose e ka sebelisoa e le tlatsetso ea ho eketsa ts'ebetso e koahelang ea thepa e sa cheng, 'me e' nile ea sebelisoa haholo ha ho lokisoa "li-thickeners" tse thibelang mollo. Hydroxyethyl cellulose e ka ntlafatsa matla a metsi le ho honyela ha lehlabathe la samente le litsamaiso tsa lehlabathe la sodium silicate. Hydroxyethyl cellulose e ka sebelisoa tlhahisong ea lifilimi le joalo ka dispersant tlhahiso ea li-slide tse nyane haholo. Thickener ka maro a nang le letsoai le lengata le sebelisoang ha ho etsoa filimi. E sebelisoa e le se tlamellang le dispersant e tsitsitseng bakeng sa lisebelisoa tsa fluorescent ka liphahlo tsa fluorescent tube. 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. E ka sebelisoa ho etsa li-binders tse matla haholo bakeng sa lirafshoa. Lintho tse thibelang metsi li thibela mongobo hore o se ke oa kena lithapong tse senyehileng.
