Phofo ea latex e qhalakantsoeng ke eng?

Re-dispersible latex powder, eo hape e tsejoang e le redispersible polymer powder (RDP), ke phofo e tšoeu e phallang e sa lefelloeng e fumanoang ka ho fafatsa ka ho omisa vinyl acetate-ethylene copolymer dispersion. Ke tlatsetso e ka sehloohong e sebelisoang linthong tsa kaho tse kang seretse, sekhomaretsi sa lithaele, metsoako ea ho ikemela, le litsamaiso tsa kantle tsa ho kenya le ho qeta (EIFS).

Mona ke tse ling tsa litšobotsi tsa bohlokoa le thepa ea "latex powder" e qhalakantsoeng hape:

1. Sebopeho sa Polymer: Redispersible latex powder haholo-holo e entsoe ka vinyl acetate-ethylene copolymers, le hoja li-polymers tse ling li ka 'na tsa e-ba teng ho itšetlehile ka mokhoa o itseng oa ho etsoa. Li-copolymer tsena li fana ka phofo ka likarolo tsa eona tsa sekhomaretsi, tse momahaneng le tsa ho etsa lifilimi.
2. Redispersibility ea Metsi: E 'ngoe ea litšobotsi tsa bohlokoa ka ho fetisisa tsa phofo ea latex e ka sebelisoang hape ke bokhoni ba eona ba ho hasana hape ka metsing ka mor'a ho omisa. Ha li kopane le metsi, likaroloana tsa phofo lia qhalana ho etsa emulsion e tsitsitseng, e tšoanang le ea pele ea ho hasana ha polima. Thepa ena e etsa hore ho be bonolo ho tšoara, ho boloka le ho sebelisa seretse se omileng le libopeho tsa sekhomaretsi.
3. Ho Adhesion le Momahano: Redispersible latex phofo e ntlafatsa ho khomarela le momahano oa lisebelisoa tsa samente, tse kang seretse le li-adhesives tsa lithaele. E etsa filimi ea polymer e tenyetsehang le e tšoarellang ha e omisoa, e matlafatsang matla a maqhama pakeng tsa substrate le thepa e sebelisitsoeng.
4. Flexibility le Crack Resistance: Ho kenyelletsoa ha phofo ea latex e ka sebelisoang hape ka har'a metsoako e entsoeng ka samente e fana ka ho feto-fetoha ha maemo le ho hanyetsa sehlahisoa sa ho qetela. Sena se thusa ho fokotsa kotsi ea ho senyeha ha shrinkage le ho ntlafatsa nako e telele ea nako e telele ea thepa ea kaho.
5. Ho boloka Metsi: Phofo ea latex e ka sebelisoang hape e ka ntlafatsa thepa ea ho boloka metsi ea thepa ea samente, e lumella nako e telele ea ho sebetsa le ho ntlafatsa ts'ebetso. Sena se molemo ka ho khetheha maemong a chesang le a omileng moo ho omisoa ka potlako ha seretse kapa sekhomaretsi se ka hlahang.
6. Ntlafatso ea Thepa ea Mechini: Phofo ea latex e ka sebelisoang hape e kenya letsoho ntlafatsong ea lisebelisoa tse fapaneng tsa mochini oa thepa e thehiloeng ho samente, ho kenyeletsoa matla a khatello, matla a thata, le ho hanyetsa tšusumetso. E thusa ho theha lihlahisoa tsa kaho tse matla le tse tšoarellang.

Redispersible latex powder e bapala karolo ea bohlokoa ho ntlafatseng ts'ebetso, ts'ebetso, le ho tšoarella ha thepa e thehiloeng ho samente e sebelisoang lits'ebetsong tsa kaho. Redispersibility ea eona ea metsi, thepa ea sekhomaretsi, ho feto-fetoha ha maemo, le ho hanyetsa crack ho etsa hore e be tlatsetso ea bohlokoa mefuteng e mengata ea lihlahisoa tsa mohaho.
