Ke mefuta efe ea phofo ea polymer e ka sebelisoang hape?

Redispersible polymer powders (RPP) e fumaneha ka mefuta e fapaneng, e 'ngoe le e' ngoe e etselitsoe lits'ebetso tse ikhethileng le litlhoko tsa ts'ebetso. Sebopeho, thepa, le ts'ebeliso e reriloeng ea li-RPP li ka fapana ho latela lintlha tse kang mofuta oa polymer, li-additives tsa lik'hemik'hale, le mekhoa ea tlhahiso. Mona ke mefuta e meng e tloaelehileng ea li-polymer powders tse ka sebelisoang hape:

1. Mofuta oa Polymer:
   • Ethylene-Vinyl Acetate (EVA) RPP: Li-RPP tse thehiloeng ho EVA li na le mekhoa e mengata 'me li sebelisoa haholo mesebetsing ea kaho e kang li-adhesives tsa lithaele, li-mortars, renders, le metsoako ea boipheliso. Li fana ka ho tenyetseha hantle, ho khomarela, le ho hanyetsa metsi.
   • Vinyl Acetate-Ethylene (VAE) RPP: Li-RPP tse thehiloeng ho VAE li tšoana le li-EVA RPP empa li ka fana ka ho ntlafala ha metsi le ho tšoarella nako e telele. Li loketse lits'ebetso tse kang likhomaretsi tsa lithaele, li-membrane tse tenyetsehang tse thibelang metsi, le li-sealants.
   • Acrylic RPP: Li-RPP tse thehiloeng ho Acrylic li fana ka ho khomarela hantle, ho hanyetsa boemo ba leholimo le ho tšoarella. Hangata li sebelisoa ho li-insulation and finish systems (EIFS), liphahlo tse thibelang metsi, le lirekere tse sebetsang hantle haholo.
   • Styrene-Acrylic RPP: Styrene-acrylic-based RPPs e fana ka tekanyo ea ho khomarela, ho tenyetseha le ho hanyetsa metsi. Li loketse lits'ebetso tse kang li-tile grouts, li-crack fillers le li-coatings tse entsoeng ka masela.
   • Polyvinyl Alcohol (PVA) RPP: Li-RPP tse thehiloeng ho PVA li fana ka maemo a phahameng a feto-fetohang, thepa ea ho etsa lifilimi, le ho hanyetsa alkalis. Hangata li sebelisoa lipenteng tsa ka hare, lipente tse entsoeng ka letsoho le li-plaster tse khabisitsoeng.
2. Li-additives tse sebetsang:
   • Li-Plasticizers: Li-RPP tse ling li ka ba le li-plasticizers ho ntlafatsa ho tenyetseha, ho sebetsa le ho khomarela. Li-RPP tse entsoeng ka polasetiki hangata li sebelisoa ho li-membrane tse tenyetsehang tsa ho thibela metsi, li-sealants le li-crack fillers.
   • Li-stabilizers: Li-stabilizer li eketsoa ho liforomo tsa RPP ho ntlafatsa bophelo ba lishelefo, botsitso ba polokelo, le ho qhalana. Li thusa ho thibela agglomeration le ho etsa bonnete ba ho hasana ho tšoanang ha likaroloana tsa RPP metsing.
3. Boholo ba Karolo le Morphology:
   • Li-RPP li fumaneha ka boholo bo fapaneng ba likaroloana le morphologies ho fihlela litlhoko tse khethehileng tsa kopo. Likaroloana tse ntle li ka fana ka sebopeho se betere sa filimi le boreleli ba bokaholimo, athe likaroloana tse mahoashe li ka ntlafatsa ho boloka metsi le thepa ea mochini.
4. Mephato e Ikgethileng:
   • Baetsi ba bang ba fana ka limaraka tse ikhethang tsa li-RPP tse etselitsoeng lits'ebetso tse itseng kapa litšobotsi tsa ts'ebetso. Tsena li ka kenyelletsa li-RPP tse nang le khanyetso e matlafalitsoeng ea metsi, botsitso ba leqhoa, kapa thepa e laoloang ea tokollo.
5. Mekhoa e Tloaelehileng:
   • Ntle le mefuta e tloaelehileng, litlhophiso tsa tloaelo tsa RPP li ka ntlafatsoa ho fihlela litlhoko tse ikhethang tsa bareki kapa merero. Li-RPP tsa tloaelo li ka kenyelletsa li-polymers, li-additives, kapa li-modifiers tse ikhethileng tse ipapisitseng le litlhaloso tsa bareki.

mefuta e fapaneng ea li-polymer powders tse fumanehang 'marakeng li bonts'a litlhoko tse fapaneng tsa liindasteri tse joalo ka kaho, lipente le likoahelo, likhomaretsi le masela, moo li-RPP li bapalang karolo ea bohlokoa ho ntlafatseng ts'ebetso ea sehlahisoa, ho tšoarella le ts'ebetso.
