Kakaretso ea phofo ea Re-Dispersible polymer
Re-dispersible polymer powder (RDP) ke mofuta oa thepa ea polymer e sebelisoang haholo indastering ea kaho. Ke phofo e tšoeu kapa e bosoeu e entsoeng ka li-emulsion tsa polymer tse omisang. Phofo e hlahisoang e ka kopanngoa habonolo le metsi ho etsa sekontiri se tsitsitseng se ka sebelisoang e le se tlamang, sekhomaretsi kapa ho roala.
Li-RDP li atisa ho sebelisoa mefuteng e mengata ea kaho, ho kenyelletsa le li-adhesives tsa lithaele, li-grouts, metsoako ea ho ikemela, le lisebelisoa tsa ka ntle tsa ho pata le ho qeta (EIFS). Li boetse li sebelisoa ha ho etsoa seretse sa motsoako o omileng, e leng motsoako o tsoakiloeng oa samente, lehlabathe le lintho tse ling tse sebelisetsoang ho etsa konkreite, samente le thepa e ’ngoe ea mohaho.
Thepa ea li-RDP e ka fapana ho latela mofuta o itseng oa polymer e sebelisitsoeng, hammoho le ts'ebetso ea tlhahiso. Leha ho le joalo, ka kakaretso, li-RDP li na le litšobotsi tse latelang:
1. Matla a phahameng a tlamang: Li-RDP li ka theha maqhama a matla ka mefuta e sa tšoaneng ea substrates, ho akarelletsa le konkreite, lehong le tšepe.
2. Ho hanyetsa metsi: Li-RDP li hanyetsana haholo le metsi, e leng se etsang hore e be tse loketseng ho sebelisoa libakeng tse mongobo.
3. Ho feto-fetoha ha maemo: li-RDP li ka etsoa hore li be bonolo, tse li lumellang ho mamella khatello ea maikutlo le ho sisinyeha ntle le ho phunyeha kapa ho senya.
4. Ho sebetsa hantle: Li-RDP li ka tsoakoa habonolo le metsi ho etsa pente e boreleli, e sebetsang kapa e emisoa.
5. Ho khomarela hantle: RDPs e ka tlamahane hantle le mefuta e sa tšoaneng ea li-substrates, ho kenyelletsa le libaka tse nang le porous le tse se nang porous.
6. Ho hanyetsa lik'hemik'hale hantle: Li-RDP li hanyetsana haholo le mefuta e mengata ea lik'hemik'hale, ho akarelletsa le li-acids, li-bases le li-solvents.
Ho na le mefuta e mengata e fapaneng ea li-RDP tse fumanehang 'marakeng, e' ngoe le e 'ngoe e na le thepa le litšobotsi tsa eona tse ikhethang. E meng ea mefuta e tsebahalang haholo e kenyelletsa:
1. Li-copolymers tsa Ethylene-vinyl acetate (EVA): Li-RDP tsena li feto-fetoha haholo 'me li na le mokhoa o babatsehang oa ho khomarela mefuta e mengata ea li-substrates. Hangata li sebelisoa ho li-adhesives, grouts le EIFS.
2. Vinyl acetate-ethylene (VAE) copolymers: Li-RDP tsena li na le metsi a mangata haholo 'me li na le ho khomarela hantle ho mefuta e sa tšoaneng ea substrates. Hangata li sebelisoa ho li-insulation tsa ka ntle le mekhoa ea ho qetela (EIFS), hammoho le li-adhesives le li-grouts.
3. Li-copolymers tsa Styrene-butadiene (SB): Li-RDP tsena li feto-fetoha haholo 'me li na le mokhoa o babatsehang oa ho khomarela mefuta e sa tšoaneng ea substrates. Hangata li sebelisoa ho li-adhesives, grouts le EIFS.
4. Acrylics: Li-RDP tsena li thibela metsi haholo 'me li khomarela hantle ho mefuta e sa tšoaneng ea substrates. Hangata li sebelisoa ho li-insulation tsa ka ntle le mekhoa ea ho qetela (EIFS), hammoho le li-adhesives le li-grouts.
5. Polyvinyl alcohol (PVA): Li-RDP tsena li na le metsi a mangata haholo 'me li na le ho khomarela hantle ho mefuta e sa tšoaneng ea substrates. Hangata li sebelisoa ka har'a seretse sa motsoako o omileng le joalo ka setlamo sa ho roala pampiri.
Ntle le ts'ebeliso ea bona indastering ea kaho, li-RDP li boetse li sebelisoa lits'ebetsong tse ling tse fapaneng, ho kenyelletsa:
1. Liaparo tsa masela: Li-RDP li ka sebelisoa e le seaparo sa masela ho ntlafatsa ho thibela metsi le ho tšoarella nako e telele.
2. Lipente le liphahlo: Li-RDP li ka sebelisoa e le se tlamang lipente le liphahlo ho ntlafatsa ho khomarela le ho thibela metsi.
3. Likhomaretsi: Li-RDP li ka sebelisoa e le setlamo sa li-adhesive ho ntlafatsa matla a tsona le ho thibela metsi.
4. Lihlahisoa tsa tlhokomelo ea botho: Li-RDP li ka sebelisoa lihlahisoa tsa tlhokomelo ea botho, tse kang li-gel tsa moriri le litlolo tsa letlalo, ho ntlafatsa sebopeho sa tsona le botsitso.
Ka kakaretso, li-polymer powders tse qhalakantsoeng hape ke lisebelisoa tse ngata le tsa bohlokoa indastering ea kaho le ho feta. Ka thepa ea bona e ikhethang le mefuta e mengata ea likopo, ba na le bonnete ba hore ba tla tsoela pele ho bapala karolo ea bohlokoa liindastering tse ngata lilemong tse tlang.
