Hydroxethyl cellulosese (Hec) ke ntho ea bohlokoa ea cellulose, e sebelisoang khafetsa khoebong ea Paint e le Thrigery, Stabilizer Morifier. E ka ntlafatsa phokotsi le botsitso ba pente le ho ntlafatsa thepa ea eona ea lifilimi.
1. Thepa le mesebetsi ea hydroxethyl cellulosese
1.1 Thepa ea mantlha
Hydroxethyl cellulosese ke polymer ea qhibilihang ea metsi e entsoeng ka ho hlahisa lihlopha tsa hydroythl ka celdroelose. Litšobotsi tsa eona li kenyelletsa:
SELUBIL ea Metsi: e qhibiliha habonolo metsing ho theha mofuta o mosoeu oa lebese le lesoeu.
Phallo ea liketsahalo: Ke pono ea tharollo e ka laoloang ka ho fetola khatello ea maikutlo.
PH
Biodegradadity: Botsoalle ba tikoloho.
Mesebetsi ea 1.2
Ka pente, lits'ebeletso tsa mantlha tsa hydroxethyl cellulouse e akaretsang:
Ho holisa: eketsa pono ea pente, ntlafatsa ho emisoa le ho makala ha eona.
Matlafatso: Thibela Seditiontion ea BIMment le ho ntlafatsa tsitsipano ea polokelo.
Puisano ea Rheoology: Theha thepa ea Rheology ea pente le ho laola phokatsi le ho lekola pente nakong ea kaho.
2. Mehato ea ho kenyelletsa hydroxethyl celdoulose
2.1 Ho itokisetsa
Tlhahiso ea koae, litokisetso tse latelang lia hlokahala bakeng sa ho eketsa hydroxethyl celdoulose:
Litokisetso tsa lintho tse bonahalang: Khetha mofuta o nepahetseng le tsebiso ea hydroxethyl cellulose (joalo ka limaraka tse fapaneng tsa limaraka tsa ho ema le tse fapaneng.
QETELLOANG MEDIUM: Lokisetsa motho ea mahareng bakeng sa ho qhibiliha saydrothbethyl cem cebhalose ea hydrothyl, hangata metsi kapa tharollo ea ho holofala.
2.2 Ts'ebetso ea ho qhibiliha
Ho hasanya: Butle-butle fydroxethyl celdroebethll Ceploulose ka metsing a batang. Ho qoba ho fetoha ha mohopolo, cellulose e ka ba e tona e nang le palo e itseng ea glycerol kapa moemeli e mong oa li-anti-cooki.
Ho susumetsoa: Boloka ho hlohlelletsa ho khothaletsa ho hasaha ha clluulose ka metsing. Lebelo le hlasimollang le lokela ho potlaka ka ho lekaneng ho qoba ho etsoa ha litoka, empa eseng ho phahame haholo ho kenyelletsa moea o mongata.
Ho ruruha: Lumella celluulose ea ho ruruha ka botlalo metsing. Hangata ho nka metsotso e 30 ho isa lihora tse 'maloa, ho latela mofuta le tshwantsho ya cellulose.
Ho futhumatsa (ka boikhethelo): Bakeng sa mefuta e meng ea selefounu, metsi a ka khona ho futhumatsa ka mokhoa o itekanetseng (hangata ha a feta 50 ° C) ho potlakisa ts'ebetso ea ho qhala.
Qhala: Tsoela pele ho hlohlelletsa ho fihlela cellulose e qhibilihile ka botlalo le tharollo ea yunifomo e thehoa. Tharollo e nyahamisitsoeng e lokela ho ba pepeneneng kapa e phatsimang, ntle le likaroloana tse totobetseng kapa celsing e sa sebetseng.
2.3 Eketsa ho koaloa
Tokisetso ea Thapelo ea Pele ea Thapelo ea Hydroxethyl hangata e qhibiliha ebile e lokisoe tharollo ea pele, e ka eketsoa ka nako e tsoaloang. Sena se tiisa hore celluulose e ajoa ka ho fetisisa e koahelang.
TLHOKOMELISO: Ho ekelletsa moo: butle-butle eketsa celdroyethyl celdroulle ha cellulose e tsoakaneng sebakeng se susumetsang. Tsoelang pele ho bona ka mokhoa o ts'oanang ho thibela sebopeho sa li-clots.
Ho kopanya: Tsoela pele ho hlohlelletsa nakong ea ts'ebetso eohle le kamora ho eketsoa ho netefatsa hore Cellulose e ajoa ka matla ka ho koaheloa.
Ho etsa tlhahlobo le phetoho: ho leka liketsahalo, ho koahela le ho beha thepa ea bohlokoa kapa ho lekana ho fihlela ts'ebetso e lebelletsoeng.
3. Litšitiso
3.1 thibela caking
Lebelo la ho fafatsa: Fafatsa hydroxethyl ho qoba ho eketsoa haholo ka nako e le 'ngoe.
Ho hlohlelletsa: boloka lebelo le tsitsitseng la ho tsitsipanya ho qoba ho lahla.
3.2 Taolo ea mocheso
Qoba mocheso o phahameng: Mocheso o phahameng o ka baka litšila tsa hydroxethyl celdouddlese, hangata li ne li laoloa ka tlase ho 50 ° C.
Ho futhumatsa ho futhumatsa ka tsela e leka-lekaneng: Ho o futhumatsa ka tsela e leka-lekaneng ho ka potlakisa ho felisoa, empa u ele hloko taolo ea mocheso.
3.3 Taolo ea PH
Setsi sa ho se nke lehlakore: Hydroxethyl Clumulose hantle ka ho se nke lehlakore kapa hanyane ka hanyane.
3.4 Boloka tharollo
Thibela tšilafalo ea bacterical: Tharollo e ts'oaroa habonolo ke likokoana-hloko ebile e hloka ho eketsoa ka liphofu kapa tsa bolokoa ka lithemparetjha tse tlase.
Shel Life: Ho khothalletsoa ho e sebelisa kapele kamoo ho ka khonehang kamora ho itokisetsa ho netefatsa ts'ebetso e nepahetseng.
4. Likhetho tsa kopo
4.1 Penterior wall pente ea lebota
Ka lebota la morao la latex pente, hydroxyeyl contlelose e ntle, ntlafatsa ts'ebetso ea kaho le boleng bo etsang lifilimi tse etsang filimi.
4,2 Pantry Paint Paint
Ka pente ea lebota ea kantle, ho eketsa hydroxethyl celdrothbeyl deldulese ea boemo ba leholimo bo ka ntlafatsa ho hanana le boemo ba leholimo bo ka ntlafatsang ha boemo ba leholimo bo ka ntlafatsang ho hana le ho phela jwantswa le ho tšoarella ha yunifomo.
4.3 pente ea lehong e thehiloeng metsing
Ka pente e thehiloeng metsing, hydroxyethyl conlloulose e ka u fa leseli le letle, 'me u ntlafatse pepenene le mathata a koae.
Joaloka mokuli oa thipa ea thckener le rheology. Nakong ea ts'ebetso ea tlhahiso, tlhokomelo e lokela ho lefuoa ho ba sotlehileng, kenyelletso ea tikoloho le maemo a tikoloho ho qoba ho alaglometion le honyora. Likopo tse sebetsang, boleng le ts'ebetso ea likoloha li ka ntlafatsoa ka nepo ka tatellano le mekhoa e sebetsang.
