Liphetoho tsa Polymer

Polymer modifiers ke lintho tse kenyellelitsoeng ho li-polymer ho ntlafatsa ts'ebetso ea tsona kapa ho fana ka thepa e ncha. Ho na le mefuta e fapaneng ea li-modifiers tsa polymer, ho kenyelletsa li-filler, li-plasticizers, li-crosslinking agents, le li-diluents tse sebetsang, har'a tse ling. Mofuta o mong oa polymer modifier o sebelisoang hangata thepa ea kaho ke Redispersible Polymer Powder (RDP).

Redispersible Polymer Powder (RDP) ke mofuta oa mofetoleli oa polymer o sebelisoang linthong tsa kaho joalo ka seretse sa samente, sekhomaretsi sa lithaele le metsoako ea ho ikemela. E entsoe ka ho omisa motsoako oa emulsion ea polymer le colloid e sireletsang, 'me hangata e thehiloe holim'a vinyl acetate-ethylene (VAE) kapa ethylene-vinyl acetate (EVA) copolymers.

RDP ke phofo e tsoeu, e phallang mahala e ka qhalakanngoang habonolo ka metsing. Ha e kopantsoe le metsi le lisebelisoa tsa samente, e etsa filimi e tsitsitseng, e tenyetsehang le e tšoarellang e ntlafatsang thepa ea thepa ea kaho. Melemo e meng ea ho sebelisa RDP joalo ka polymer modifier e kenyelletsa:

1. Ntlafatso ea ts'ebetso: RDP e ntlafatsa ts'ebetso ea lisebelisoa tsa samente ka ho fokotsa metsi le ho ntlafatsa rheology. Sena se fella ka ho khomarela hantle, ho tšoara habonolo, le ho fokotsa ho phunyeha.
2. Matla a eketsehileng: RDP e ntlafatsa matla le ho tšoarella ha thepa ea samente ka ho eketsa matla a bonto le ho fokotsa ho kenella ha metsi. Sena se fella ka thepa ea kaho e matla le e tšoarellang haholoanyane.
3. Ho hanyetsa metsi le lik'hemik'hale hamolemo: RDP e ntlafatsa ho hanyetsa ha thepa ea samente ho metsi le lik'hemik'hale ka ho fokotsa porosity le ho ntlafatsa ho se khonehe. Sena se fella ka thepa ea kaho e sa keneleng metsi le e hananang le lik'hemik'hale.
4. Ho khomarela hamolemo: RDP e ntlafatsa ho khomarela lisebelisoa tsa samente ho li-substrates tse fapaneng, ho kenyeletsoa konkreite, masonry le lehong. Sena se fella ka maqhama a matla le a tšoarellang pakeng tsa thepa ea kaho le substrate.

RDP e sebelisoa linthong tse fapaneng tsa kaho, ho kenyelletsa:

1. Seretse sa Cementitious: RDP e sebelisoa liretseng tsa samente tse kang likhomaretsi tsa lithaele, li-grouts le li-renders. E ntlafatsa ts'ebetso, matla le ho tšoarella ha lisebelisoa tsena, e leng se etsang hore e qetelle e betere le ho phela nako e telele.
2. Metsoako ea ho ikemela: RDP e sebelisoa metsoakong ea ho ikemela ho ntlafatsa phallo ea eona le thepa ea ho lekanya. E boetse e ntlafatsa matla le ho tšoarella ha tsona, e leng se etsang hore li qetelle li le betere.
3. Lihlahisoa tse thehiloeng ho Gypsum: RDP e sebelisoa lihlahisoa tse entsoeng ka gypsum tse kang metsoako e kopantsoeng le li-plaster. E ntlafatsa ts'ebetso, matla, le ho tšoarella ha lihlahisoa tsena, e leng se etsang hore li qetelle hantle le nako e telele ea bophelo.
4. Lisebelisoa tse sireletsang mocheso: RDP e sebelisoa linthong tse sireletsang tse kang lirekere tsa mocheso le liaparo. E ntlafatsa ho khomarela, matla, le ho tšoarella ha lisebelisoa tsena, e leng se etsang hore e be le tšireletso e ntle le nako e telele ea bophelo.

Qetellong, Redispersible Polymer Powder (RDP) ke mofuta oa polymer modifier e sebelisoang hangata ho thepa ea kaho ho ntlafatsa thepa ea bona. E ntlafatsa ho sebetsa, matla le ho tšoarella ha thepa ea samente, e fellang ka qetello e betere le nako e telele ea bophelo. RDP e sebelisoa linthong tse fapaneng tsa kaho tse kang lirekere tsa samente, metsoako e itšebetsang, le lihlahisoa tse entsoeng ka gypsum, har'a tse ling.
