Redispersible Polymer Powder (RDP) ke eng?

Redispersible Polymer Powder (RDP) ke phofo e sa lefelloeng, e tšoeu kapa e tšoeu e fumanoang ho tloha li-emulsion tsa polymer ka mokhoa oa ho omisa. Ha e kopana le metsi, RDP e arolelana hape ka emulsion e tsitsitseng, e tsosolosa thepa ea eona ea pele le ho ntlafatsa litšobotsi tsa mochine le lik'hemik'hale tsa thepa e sa tšoaneng ea mohaho.

Sebopeho sa Lik'hemik'hale sa RDP

RDP e na le:

• Motheo oa polymer: Vinyl acetate-ethylene (VAE), acrylic, kapa styrene-butadiene
• Li-colloids tse sireletsang: joala ba polyvinyl (PVA)
• Tlatsetso: Li-anti-caking agents tse kang silica
• Lisebelisoa tsa polasetiki: Ho ntlafatsa ho tenyetseha le ho khomarela
• Liemeli tse tlosang lekhooa: Ho laola litaba tsa moea ha ho etsoa

Kamoo Powder ea Polymer e Redispersible e Sebetsang Kateng

Ha RDP e kopantsoe le metsi, e theha phallo e tsitsitseng ea polima. Phatlalatso ena e ntlafatsa ho khomarela, momahano, le ho fetoha habonolo ha seretse le lihlahisoa tse ling tsa samente. Likaroloana tsa polymer li tlatsa likheo ka har'a matrix a seretse, li fokotsa ho kenella ha metsi ha li ntse li matlafatsa matla le ho tšoarella.
