VAE redispersible powders ke mofuta oa phofo ea polymer e sebelisoang haholo indastering ea kaho. Li entsoe ka copolymer ea vinyl acetate le ethylene (VAE), e kopantsoeng le mefuta e meng ea li-additives ho etsa phofo e ka kopanngoang habonolo le metsi. Sehlahisoa se hlahisoang se ka sebelisoa bakeng sa mefuta e mengata ea lisebelisoa, ho kenyelletsa li-adhesives tsa lithaele, li-grouts, li-renders tse thehiloeng ho samente, le lisebelisoa tsa ka ntle tsa ho kenya le ho qeta (EIFS).

VAE redispersible powders e tumme lilemong tsa morao tjena ka lebaka la thepa ea bona e ntle ea ts'ebetso le boiketlo ba tšebeliso. Sengoliloeng sena, re tla hlahloba thepa, melemo, le ts'ebeliso ea phofo ea VAE e ka sebelisoang hape.

Thepa ea VAE Redispersible Powders:

1. High Redispersibility: E 'ngoe ea thepa ea bohlokoahali ea VAE redispersible powders ke bokhoni ba bona ba ho hasana hape ka metsing. Sena se bolela hore ha phofo e kopantsoe le metsi, e etsa emulsion e tsitsitseng e ka phatlalatsoang habonolo le ho sebelisoa libakeng tse sa tšoaneng.
2. Khomarelo e Ntle: Li-powders tse ka qhaqhoang tsa VAE li na le thepa e ntle ea ho khomarela, e li etsang hore e be tse loketseng ho sebelisoa ho likhomaretsi tsa lithaele le li-grouts. Li ka hokahana le libaka tse ngata tse fapaneng, ho kenyeletsoa konkreite, lehong le ceramic.
3. Metsi a hanyetsanang le Metsi: Li-powders tse qhaqhoang tsa VAE ha li na metsi, e leng se etsang hore li be tse loketseng bakeng sa ho sebelisoa ka ntle ho li-insulation and finishing systems (EIFS) le liphetolelo tse thehiloeng ho samente. Li ka thusa ho thibela metsi ho kena ka holim'a metsi, e leng se ka bakang tšenyo le ho senyeha ha nako e ntse e ea.
4. Ho feto-fetoha ha maemo: Li-powders tse qhalakahang tsa VAE li na le phetoho e ntle haholo, e li etsang hore e be tse loketseng bakeng sa ho sebelisoa ho likhomaretsi tsa lithaele tse manganga le li-grouts. Li khona ho mamella motsamao le deformation ntle le ho petsoha kapa ho robeha.
5. Freeze-Thaw Stability: VAE redispersible powders e na le botsitso bo botle ba ho qhibiliha, e leng se etsang hore e be tse loketseng ho sebelisoa libakeng tse batang. Ba ka mamella lipotoloho tse ngata tsa leqhoa ntle le ho lahleheloa ke thepa ea bona ea ts'ebetso.

Melemo ea VAE Redispersible Powders:

1. Mokhoa o Ntlafetseng oa ho sebetsa: Li-powders tsa VAE tse ka sebelisoang hape li ntlafatsa ho sebetsa ha lihlahisoa tse entsoeng ka samente, ho etsa hore ho be bonolo ho li jala le ho li sebelisa. Li ka boela tsa ntlafatsa ho tsitsisa ha sehlahisoa sa ho qetela, ho fella ka sebaka se boreleli le se ts'oanang.
2. Matla a Eketsehileng: Li-powders tsa VAE tse ka sebelisoang hape li ka eketsa matla a lihlahisoa tse entsoeng ka samente. Li ka thusa ho ntlafatsa matla a maqhama pakeng tsa sehlahisoa le substrate, e leng se hlahisang sebaka se matla le se tšoarellang haholoanyane.
3. Ho Fokotsa Shrinkage: Liphofshoana tse qhalakahang tsa VAE li ka thusa ho fokotsa ho honyela ha lihlahisoa tse entsoeng ka samente. Sena se ka thusa ho thibela ho phunyeha le ho ntlafatsa ponahalo ea kakaretso le nako e telele ea sehlahisoa.
4. Litšenyehelo: Li-powders tse qhaqhoang tsa VAE ke tharollo e theko e tlaase bakeng sa ho ntlafatsa ts'ebetso ea lihlahisoa tse entsoeng ka samente. Li ka thusa ho fokotsa litšenyehelo tse akaretsang tsa morero ka ho ntlafatsa ts'ebetso, matla le ho tšoarella ha sehlahisoa.

Lisebelisoa tsa VAE Redispersible Powders:

1. Li-Adhesives tsa Lithaele: Li-powder tse ka reketsoang tsa VAE li sebelisoa haholo ho li-adhesive le li-grouts. Ba ka ntlafatsa ho khomarela le ho feto-fetoha ha sehlahisoa, ho fella ka maqhama a matla le a tšoarellang pakeng tsa tile le substrate.
2. Li-Renders tse thehiloeng ho Cement: Li-powders tse qhalakahang tsa VAE li sebelisoa mefuteng e thehiloeng ho samente ho ntlafatsa ts'ebetso, matla le ho tšoarella ha sehlahisoa. Li ka thusa ho fokotsa ho honyela le ho petsoha, ho fella ka sebaka se boreleli le se ts'oanang.
3. Exterior Insulation and Finishing Systems (EIFS): VAE redispersible powders e sebelisoa ho EIFS ho ntlafatsa ho thibela metsi le ho tšoarella ha sehlahisoa. Li ka thusa ho thibela tšenyo ea mongobo le boemo ba leholimo, e leng se etsang hore mohaho o phele nako e telele.
