hpmc rdp e sebelisoang ho Cement Render & Plaster EIFS & ETICS
JINJI® HPMC e na le thepa e fapaneng e etsang hore e sebetse hantle le ho ratoa bakeng sa EIFS&ETICS.
Thermal insulation board system, ka kakaretso e kenyelletsa ETICS (EIFS) (External Thermal Insulation Composite System / Exterior Insulation Finish System), e le ho boloka litšenyehelo tsa ho futhumatsa kapa matla a pholileng, seretse se setle sa ho tlama se hloka ho ba le: ho bonolo ho kopanya, ho bonolo ho sebetsa, thipa e sa thupeng; Tšusumetso e ntle ea anti-hanging; Ho khomarela hantle ha pele le litšobotsi tse ling. Seretse sa samente se hloka ho ba le: ho bonolo ho sisinyeha, ho jala habonolo, thipa e sa thupeng, nako e telele ea nts'etsopele, bokhoni bo botle ba ho koloba bakeng sa lesela la marang-rang, ha ho bonolo ho koahela le litšobotsi tse ling. Litlhoko tse ka holimo li ka finyelloa ka ho kenyelletsa lihlahisoa tse loketseng tsa cellulose ether tse kang Hydroxypropyl Methyl Cellulose (HPMC) seretseng.
Lihlahisoa tsa rona tsa HPMC cellulose le sehlahisoa sa RDP li fana ka lintlafatso tse latelang ho EIFS:
• Matla a ntlafetseng a sekhomaretsi le ho feto-fetoha ha maemo: selulose e na le ts'ebetso e ntle ea thickening le lubricity, e ka ntlafatsang matla a ho khomarela le ho feto-fetoha ha sekhomaretsi sa EIFS.
• Ntlafatso ea ho boloka metsi le nako e atolositsoeng ea ho sebetsa: ho fokotsa haholo tahlehelo ea metsi hore e be li-substrates tse monyang ha li etsoa. Bokhoni ba ho boloka metsi ba cellulose bo boetse bo matlafatsa matla a ho khomarela a li-adhesive tsa EIFS. Sena se bakoa ke hore li-binders li na le nako e lekaneng ea hydration 'me ka nako e ts'oanang ha li lahleheloe ke metsi.
• Ts'ebetso e ntlafalitsoeng ea sehlahisoa le rheology: selulose ke senotlolo sa ho lokisa ho ts'oana ho loketseng liretseng tse ncha. Ho tsitsa ho loketseng ho etsa hore samente e ncha e hokele hantle maboteng hammoho le ho etsa hore bokaholimo bo be boreleli le ho sebelisoa habonolo ntle le maikutlo a ho khomarela. Tharollo ea metsi ea MelaColl ke tsamaiso e seng ea Newtonian, 'me thepa ea tharollo ea eona e bitsoa thixotropy.
• Hydrophobicity e ntlafetseng: Ka mor'a ho eketsa selulose, hydrophobicity ea EIFS e ntlafetse, phello ea ho thibela metsi e eketseha haholo.
• Ts'ebetso e ntlafetseng: Ho lekana hantle le ho fokotsa ho khomarela ha selulose ho ka sebelisoa habonolo ho li-adhesives tsa EIFS, tse sebetsang habonolo le ho hahoa, 'me li ka ntlafatsa haholo ts'ebetso ea kaho.
• Ntlafatsa ts'ebetso ea ho roala ka matla a pele a matla: selulose e kopanya momahano oa thepa ea polymer le ho tšoarella ha lisebelisoa tsa inorganic. Ba ka netefatsa matla a pele a seretse le thepa e 'ngoe ea bohlokoa e hlokahalang ho EIFS le kaho e ncha.
• Ho hanyetsa metsi hantle, ho lumellana hantle le lihlahisoa tse akaretsang: cellulose e fokotsa haholo tahlehelo ea metsi ka har'a li-substrates tse monyang ha li etsoa. Bokhoni ba ho boloka metsi ba cellulose bo boetse bo matlafatsa matla a ho khomarela a li-adhesive tsa EIFS. Sena se bakoa ke hore li-binders li na le nako e lekaneng ea hydration 'me ka nako e ts'oanang ha li lahleheloe ke metsi.
• Bontša matla a phahameng, ho khomarela ka matla, le ho hanyetsa alkali: selulose e na le ho boloka hantle, thepa e teteaneng, Thepa e tsitsitseng ea lik'hemik'hale ka katleho e hanela tlhaselo ea alkali.
