VeoVa Based Redispersible Polymer Powder

VeoVa-based redispersible polymer powder (RDP) ke mofuta oa tlatsetso ea phofo e sebelisoang hangata ho thepa ea kaho, joalo ka seretse, sekhomaretsi sa lithaele le li-renders. VeoVa e bua ka lelapa la vinyl ester monomers e nkiloeng ho vinyl acetate le versatic acid. Mona ke kakaretso ea RDP e thehiloeng ho VeoVa:

1. Sebopeho:

• Li-RDP tse thehiloeng ho VeoVa ke li-copolymers tse nkiloeng ho vinyl acetate (VA) le VeoVa monomers. Ts'ebetso ea copolymerization e kopanya li-monomer tsena ho theha polymer e nang le thepa e ikhethileng e etselitsoeng lits'ebetso tse fapaneng.

2. Thepa:

• Li-RDP tse thehiloeng ho VeoVa li fana ka mefuta e mengata ea thepa e lakatsehang, ho kenyelletsa ho khomarela ho ntlafalitsoeng, ho tenyetseha, ho hanyetsa metsi, le ho tšoarella.
• Ho kenyelletsoa ha li-monomers tsa VeoVa ka har'a sebopeho sa polymer ho ntlafatsa ts'ebetso ea li-RDP ha li bapisoa le li-RDP tsa setso tse thehiloeng ho VA lits'ebetsong tse itseng, haholo-holo tse hlokang ho feto-fetoha ha maemo le ho hanyetsa metsi.

3. Likopo:

• Li-RDP tse thehiloeng ho VeoVa li sebelisoa mefuteng e fapaneng ea thepa ea kaho, ho kenyeletsoa seretse, likhomaretsi tsa lithaele, li-grouts, li-self-leveling compounds le li-membrane tse thibelang metsi.
• Li loketse ka ho khetheha bakeng sa lits'ebetso moo ho eketsehang ha maemo a bonolo le ho thibela metsi ho hlokahalang, tse kang li-renders tsa ka ntle, liphahlo tse entsoeng ka polymer-modified cementitious, le mekhoa ea ho thibela metsi.

4. Melemo:

• Ntlafatso ea ho feto-fetoha ha maemo: Li-RDP tse thehiloeng ho VeoVa li fana ka phetoho e ntlafalitsoeng, e li lumellang ho mamella motsamao oa substrate le ho fetoha ha mocheso ntle le ho phatloha.
• Ntlafatso ea Khahlano ea Metsi: Ho ba teng ha VeoVa monomers ho ntlafatsa ho hanyetsa metsi ha RDPs, ho etsa hore e tšoanelehe bakeng sa lits'ebetso tsa kantle tse pepesehileng maemo a leholimo a mabe.
• Superior Adhesion: Li-RDP tse thehiloeng ho VeoVa li fana ka sekhomaretsi se setle ho li-substrates tse fapaneng, ho kenyeletsoa konkreite, masonry, lehong le liboto tsa ho kenya letsoho, ho netefatsa maqhama a matla le ho tšoarella ha nako e telele.

5. Ho lumellana:

• Li-RDP tse thehiloeng ho VeoVa li tsamaisana le li-additives tse ling tse sebelisoang hangata ho thepa ea kaho, joalo ka samente, li-filler, li-plasticizers le li-air-entraining agents. Ho lumellana hona ho lumella ho etsoa ha seretse se ikhethileng le sekhomaretsi se lumellanang le litlhoko tse khethehileng tsa kopo.

Ka kakaretso, VeoVa-based redispersible polymer powders (RDPs) e fana ka maemo a feto-fetohang, ho hanyetsa metsi, le ho khomarela ha ho bapisoa le li-RDP tsa setso tsa VA, e leng se etsang hore li tšoanelehe bakeng sa mefuta e mengata ea likopo tsa kaho moo ho tšoarella le ho sebetsa ho leng bohlokoa.
