Motsoako o phethahetseng oa li-ether tsa cellulose tse sebetsang hantle bakeng sa Kaho le Kaho

Sebakeng sa kaho le kaho, ho fihlella ts'ebetso e nepahetseng ea thepa ke ea bohlokoa bakeng sa ho netefatsa boits'oaro ba sebopeho, ho tšoarella le ho tšoarella. Motsoako o phethahetseng oa li-cellulose ethers tse sebetsang hantle o bapala karolo ea bohlokoa ho ntlafatseng thepa le ts'ebetso ea lisebelisoa tse fapaneng tsa kaho. Ha re hlahlobeng hore na motsoako oa li-cellulose ethers tse fapaneng o kenya letsoho joang katlehong ea merero ea kaho le ea kaho:

1. Hydroxyethyl Methyl Cellulose (HEMC):
   • HEMC ke ether ea selulose e feto-fetohang e tsebahalang ka thepa ea eona e ntle ea ho boloka metsi, bokhoni ba ho tenya, le ntlafatso ea ho khomarela.
   • Likhomaretsing tsa lithaele le lirafshoa, HEMC e ntlafatsa ts'ebetso ea ho sebetsa, nako e bulehileng, le matla a ho khomarela, ho tiisa maqhama a nepahetseng pakeng tsa lithaele le li-substrates.
   • HEMC e boetse e ntlafatsa ho pompa le ho hanyetsa ho sag ea metsoako ea ho ikemela, ho thusa ho qeta ka mokhoa o boreleli esita le holim'a lisebelisoa tsa fatše.
   • Ho lumellana ha eona le lisebelisoa tse fapaneng tsa cementitious le li-additives ho etsa hore e be khetho e ratoang bakeng sa ho etsa lihlahisoa tsa kaho tse sebetsang hantle.
2. Hydroxypropyl Methyl Cellulose (HPMC):
   • HPMC e fana ka tekanyo ea ho boloka metsi, ho teteaneng, le taolo ea rheological, e etsang hore e tšoanelehe bakeng sa mefuta e mengata ea likopo tsa kaho.
   • Lits'ebetsong tsa ka ntle tsa insulation le finishes system (EIFS), HPMC e ntlafatsa ts'ebetso le momahano ea li-basecoats le li-finishing, ho netefatsa hore ho koaheloa ka mokhoa o ts'oanang le ho hanyetsa crack.
   • Li-plaster le li-plaster tse thehiloeng ho HPMC li bonts'a ho khomarela hantle ho li-substrates, ho ntlafala ha crack, le ho tšoarella ho matlafalitsoeng, leha maemo a leholimo a le thata.
   • Lintho tsa eona tsa ho etsa lifilimi li thusa ho thibela metsi le ho tšoarella ha lipente, lirafshoa le li-sealants tse sebelisoang ha ho hahoa.
3. Ethyl Hydroxyethyl Cellulose (EHEC):
   • EHEC e nkoa e le ea bohlokoa ka lebaka la katleho ea eona e matla, boitšoaro ba ho kuta, le botsitso holim'a mefuta e mengata ea pH le maemo a mocheso.
   • Ka li-grouts tsa cementitious le seretse, EHEC e ntlafatsa thepa ea rheological, e fokotsa nako ea ho kopanya le ho matlafatsa phallo le ho sebetsa.
   • Li-membrane tse thibelang metsi tse thehiloeng ho EHEC le li-sealants li bonts'a ho khomarela ka mokhoa o babatsehang ho li-substrates, bokhoni ba ho senya, le ho hanyetsa ho kenella ha metsi, ho fana ka tšireletso ea nako e telele bakeng sa mehaho ea mohaho.
   • Ho lumellana ha eona le li-additives tse fapa-fapaneng ho lumella ho etsoa ha lihlahisoa tsa kaho tse sebetsang hantle tse lumellanang le litlhoko tse khethehileng tsa morero.
4. Carboxymethyl Cellulose (CMC):
   • CMC e tumme ka bokhoni ba eona ba ho kopanya metsi, taolo ea viscosity, le thepa ea ho etsa lifilimi, e e etsa tlatsetso e loketseng bakeng sa thepa ea kaho e hlokang ho hanyetsa mongobo le ho khomarela.
   • Ka li-plaster tse thehiloeng ho gypsum le metsoako e kopantsoeng, CMC e ntlafatsa ts'ebetso, e fokotsa ho phunyeha, le ho matlafatsa ho khomarela li-substrates, e leng se etsang hore ho be le liphetho tse bonolo le ts'ebetso e ntlafetseng.
   • Likhomaretsi le li-sealants tse thehiloeng ho CMC li fana ka tackiness e phahameng, matla a bond, le ho hanyetsa mongobo le lik'hemik'hale, ho netefatsa tlamahano e tšepahalang le ho tšoarella ha nako e telele lits'ebetsong tsa kaho.
   • Bokhoni ba eona ba ho etsa lifilimi tse feto-fetohang le ho tsitsisa ho emisoa ho etsa hore e tšoanelehe ho sebelisoa lipente, liphahlo le li-stuccos, ho fana ka tšireletso le mekhabiso ea ho khabisa bakeng sa ho haha ​​​​ka ntle le ka hare.

Ka ho kopanya thepa e ikhethang ea HEMC, HPMC, EHEC, le CMC ka litekanyo tse sa tšoaneng, baetsi ba lihlahisoa ba ka hlahisa thepa ea kaho e sebetsang hantle e etselitsoeng ho finyella litlhoko tse fapaneng tsa merero ea kaho. Ebang ke ho ntlafatsa ts'ebetso, ho matlafatsa ho khomarela, kapa ho tšoarella nako e telele, motsoako o phethahetseng oa cellulose ethers o bapala karolo ea bohlokoa ho tsamaiseng boqapi le bokhabane indastering ea meaho le ea kaho.
