Methylhydroxyethylcellulose (MHEC) ke motsoako oa polymer o sebelisoang haholo ho thepa ea mohaho 'me o na le melemo e mengata ho li-putty applications. Mona ke melemo ea mantlha ea methylhydroxyethylcellulose lits'ebetsong tsa putty:
1. Ntlafatsa ts'ebetso ea kaho
1.1 Ntlafatsa ho boloka metsi
Methyl hydroxyethyl cellulose e na le ts'ebetso e ntle ea ho boloka metsi, e thusang ho lelefatsa nako e bulehileng ea putty, e lumellang mokopi nako e eketsehileng ea ho etsa liphetoho le ho ama. Ho phaella moo, ho boloka metsi hantle ho thibela putty hore e se ke ea omella ka potlako ka mor'a kopo, ho fokotsa kotsi ea ho senya le ho cheka.
1.2 Ntlafatsa mokelikeli oa kaho le ts'ebetso
MHEC e ka ntlafatsa haholo metsi a putty, e nolofaletsa ho e sebelisa le ho hasana. Sena se ka fokotsa matšoao le li-bubble nakong ea kaho le ho ntlafatsa boleng ba kaho le botle ba putty.
1.3 Fana ka ho khomarela hantle
MHEC e ka ntlafatsa ho khomarela pakeng tsa putty le substrate, ho netefatsa botsitso le ho tšoarella ha seaparo. Sena ke sa bohlokoa ka ho khetheha bakeng sa kaho libakeng tse rarahaneng kapa tse phahameng tsa mocheso, kaha li thibela putty layer hore e se ke ea ebola le ho ebola.
2. Ntlafatsa thepa ea 'mele ea putty
2.1 Ntlafatsa khanyetso ea crack
Ka lebaka la ho boloka metsi le phello ea polasetiki ea MHEC, putty e ka fokotseha ka mokhoa o ts'oanang nakong ea ho omisa, ho fokotsa monyetla oa ho omisa le ho senya. Ho tenyetseha ha putty hoa ntlafatsoa, ho e lumella ho ikamahanya hantle le mefokolo e nyane ka har'a substrate ntle le ho phatloha.
2.2 Ntlafatsa khanyetso ea ho apara
MHEC e ntlafatsa ho thatafala le ho tiea ha putty, ho etsa hore bokaholimo ba eona bo se ke ba apara. Sena ke sa bohlokoa ka ho khetheha bakeng sa marako a sebelisoang khafetsa kapa a tlas'a likhohlano, a thusa ho lelefatsa bophelo ba lerako.
2.3 Ntlafatsa khanyetso ea boemo ba leholimo
MHEC ka putty e ka ntlafatsa ho hanyetsa boemo ba leholimo, ho e lumella ho boloka ts'ebetso e tsitsitseng tlas'a maemo a fapaneng a leholimo. Ebang ke mocheso o phahameng, mocheso o tlase kapa tikoloho e mongobo, putty e ka boloka thepa ea eona e ntle ea 'mele mme ha e amehe habonolo ke liphetoho tsa tikoloho.
3. Ntlafatsa botsitso ba lik'hemik'hale tsa putty
3.1 Ntlafatsa khanyetso ea alkali
Methyl hydroxyethyl cellulose e ka ntlafatsa khanyetso ea alkali ea putty le ho thibela ho senyeha ha ts'ebetso ho bakoang ke khoholeho ea lintho tsa alkaline. Sena se tiisa hore putty e boloka ts'ebetso ea eona e ntle le ponahalo ha e kopana le lisebelisoa tse nang le alkaline joalo ka li-substrates tsa cementitious.
3.2 Ntlafatsa thepa ea antibacterial le antifungal
MHEC e na le litlamorao tse itseng tsa antibacterial le anti-mildew, tse ka thibelang kholo ea libaktheria le hlobo le ho thibela matheba a hlobo le monko ho hlaha holim'a putty. Sena se bohlokoa haholo-holo libakeng tse mongobo kapa tse mongobo ho thusa ho boloka mabota a hloekile a bile a hloekile.
4. Tšireletso ea tikoloho le melemo ea moruo
4.1 Litšobotsi tsa tšireletso ea tikoloho
Methyl hydroxyethyl cellulose ke lintho tse tala tse nang le tikoloho tse se nang chefo le tse se nang kotsi 'meleng oa motho le tikolohong. Tšebeliso ea eona e ka fokotsa tšebeliso ea lisebelisoa tse ling tse kotsi tsa lik'hemik'hale le ho fokotsa tšilafalo ea tikoloho nakong ea ts'ebetso ea kaho.
4.2 Fokotsa litšenyehelo
Le hoja litšenyehelo tsa pele tsa MHEC li ka 'na tsa e-ba tse phahameng, ts'ebetso ea eona e sebetsang hantle ka putty e ka fokotsa bongata ba thepa e sebelisoang le nako ea kopo, kahoo e fokotsa litšenyehelo tsa kaho ka kakaretso. Bophelo bo bolelele ba tšebeletso le litlhoko tse fokolang tsa tlhokomelo le tsona li fella ka melemo ea nako e telele ea moruo.
5. Mefuta e mengata ea lisebelisoa
Methyl hydroxyethyl cellulose ha e tšoanelehe feela bakeng sa putty e ka hare ea lebota, empa e boetse e sebelisoa haholo linthong tse fapaneng tsa moaho joalo ka bokantle ba lebota la putty, seretse se thibelang ho qhekella, le seretse sa ho ikemela. Ho feto-fetoha ha eona le thepa e ntle haholo e etsa hore e be tlatsetso ea bohlokoa kahong ea meaho ea sejoale-joale.
Methylhydroxyethylcellulose e na le melemo e mengata lits'ebetsong tsa putty. Ka ho ntlafatsa ho boloka metsi, metsi a kaho, ho khomarela le thepa ea 'mele, MHEC e ka ntlafatsa haholo ts'ebetso ea kaho le ho sebelisa phello ea putty. Ho feta moo, thepa ea eona ea tikoloho le melemo ea moruo le eona e etsa hore e be tlatsetso e loketseng ea thepa ea moaho. Ka nts'etsopele e tsoelang pele ea theknoloji ea kaho, litebello tsa kopo ea MHEC ka putty li tla ba tse pharaletseng.
