Hydroxyethyl cellulose (HEC)ke ether ea cellulose e seng ea ionic e entsoeng ka cellulose ea tlhaho ea polymer ka letoto la etherification. Ke phofo e tšoeu kapa granule e se nang monko, e se nang tatso, e se nang chefo, e ka qhibilihang ka metsing a batang ho etsa tharollo e bonaletsang e nang le viscous, 'me ho qhibiliha ha eona ha ho amehe ke boleng ba pH. E na le ho teteana, ho tlama, ho qhalakanya, ho emulsifying, ho etsa filimi, ho emisa, ho monya, ho sebetsa holim'a metsi, ho boloka mongobo le ho hanela letsoai. E sebelisoa haholo penteng, kahong, masela, lik'hemik'hale tsa letsatsi le letsatsi, pampiri, ho cheka oli le liindasteri tse ling.
Libaka tse ka sehloohong tsa kopo:
1. Pente: Pente e thehiloeng metsing ke mokelikeli o nang le viscous o entsoeng ka metsoako ea tlhaho kapa metsi a thehiloeng ho resin, kapa oli, kapa emulsion, ka ho eketsoa ha lintho tse ling tse tsamaellanang. Liaparo tse thehiloeng metsing tse nang le ts'ebetso e ntle li lokela ho ba le ts'ebetso e ntle ea ts'ebetso, matla a matle a ho ipata, ho khomarela ho matla ha ho roala, le ts'ebetso e ntle ea ho boloka metsi; cellulose ether ke thepa e tala e loketseng ka ho fetisisa ho fana ka litšobotsi tsena.
2. Kaho: Lefapheng la indasteri ea kaho, HEC e sebelisoa e le sehlomathiso bakeng sa thepa e kang thepa ea lebota, konkreite (ho kenyeletsoa le asphalt), lithaele tse khomaretsoeng le thepa ea caulking, e ka eketsang viscosity le teteana ea thepa ea kaho, ea ntlafatsa ho khomarela, ho tlotsa le ho boloka metsi. Ntlafatsa matla a ho kobeha ha likarolo kapa likarolo, ea ntlafatsa ho fokotseha, 'me ea qoba mapetso a mathōko.
3.Textile: k'hothone e phekotsoeng ke HEC, likhoele tsa maiketsetso kapa metsoako li ntlafatsa thepa ea tsona joalo ka ho hanyetsa ho khohlela, ho daea, ho hanyetsa mollo le ho hanyetsa matheba, hammoho le ho ntlafatsa botsitso ba 'mele oa tsona (ho fokotseha) le ho tšoarella, haholo-holo bakeng sa likhoele tsa maiketsetso, e leng se etsang hore li heme habonolo le ho fokotsa motlakase o sa fetoheng.
4. Khemikhale ea letsatsi le letsatsi: Cellulose ether ke tlatsetso ea bohlokoa lihlahisoa tsa lik'hemik'hale tsa letsatsi le letsatsi. E ke ke ea ntlafatsa feela viscosity ea litlolo tsa metsi kapa tsa emulsion, empa hape e ntlafatsa ho hasana le botsitso ba foam.
5.Pampiri: Lefapheng la ho etsa pampiri, HEC e ka sebelisoa e le moemeli oa boholo, moemeli oa ho matlafatsa le modifier ea pampiri.
6. Ho cheka oli：HEC e sebelisoa haholo-holo e le moemeli oa ho tiisa le ho tiisa ts'ebetsong ea kalafo ea oli. Ke k'hemik'hale e ntle ea oli. E ne e sebelisoa haholo ho chekeng, ho phetheng liliba, ho tiisa samente le mesebetsi e meng ea tlhahiso ea oli linaheng tse ling lilemong tsa bo-1960.
Masimo a mang a kopo:
HECe ka bapala karolo ea ho khomarela chefo makhasing ts'ebetsong ea ho fafatsa; HEC e ka sebelisoa e le sethibisi bakeng sa li-emulsion tsa spray ho fokotsa ho fafatsa ha lithethefatsi, ka hona e eketsa phello ea ts'ebeliso ea ho fafatsa makhasi. HEC e ka boela ea sebelisoa e le moemeli ea etsang filimi ho li-agent tsa peo; e le sethibisi ho sebelisoeng hape ha makhasi a koae. Hydroxyethyl cellulose e ka sebelisoa e le sehlomathiso ho eketsa ts'ebetso ea ho koahela thepa e sa cheng, 'me e sebelisitsoe haholo ho lokiseng "li-thickeners tse sa cheng". Hydroxyethyl cellulose e ka ntlafatsa matla a metsi le ho fokotseha ha lehlabathe la samente le litsamaiso tsa lehlabathe la sodium silicate. Hydroxyethyl cellulose e ka sebelisoa tlhahisong ea lifilimi le e le sethibisi tlhahisong ea li-slide tse nyenyane. Sethibisi ka har'a metsi a nang le letsoai le phahameng le sebelisoang ts'ebetsong ea filimi. E sebelisoa e le sethibisi le sethibisi se tsitsitseng bakeng sa li-agent tsa fluorescent ho li-coat tsa tube tsa fluorescent. E ka sireletsa colloid tšusumetsong ea mahloriso a electrolyte; hydroxyethyl cellulose e ka khothaletsa ho kenngoa ho tšoanang ka har'a tharollo ea cadmium plating. E ka sebelisoa ho etsa li-binder tse matla haholo bakeng sa li-ceramic. Lintho tse thibelang metsi li thibela mongobo ho kena ka har'a likhoele tse senyehileng.
