Tšebeliso ea phofo ea VAE RDP ka har'a seretse se fapaneng sa kaho

1. Selelekela:

Tsoelo-pele ea thepa ea mohaho e lebisitse ho nts'etsopele ea li-additives tse kang redispersible polymer powders (RDP), tse phethang karolo ea bohlokoa ho ntlafatsa ts'ebetso ea lisebelisoa tsa mohaho.Har'a mefuta e fapaneng ea RDP, vinyl acetate-ethylene (VAE) RDP e hlahella ka ho feto-fetoha ha eona le katleho ea eona mefuteng e fapaneng ea litlolo tsa seretse.

2. Litšobotsi tsa phofo ea VAE RDP:

VAE RDP phofo e entsoe ka copolymerized ho tloha vinyl acetate le ethylene.Sena se hlahisa phofshoana e ntle, e sa lefelloeng e nang le dispersibility e babatsehang ka metsing.Thepa ea bohlokoa ea VAE RDP e kenyelletsa matla a phahameng a bond, ho tenyetseha hantle le ho lumellana le mefuta e fapaneng ea thepa ea samente.Mehaho ena e etsa hore VAE RDP e be tlatsetso e loketseng bakeng sa ho ntlafatsa ts'ebetso ea seretse sa kaho.

3. Tšebeliso ea VAE RDP mefuteng e mengata ea kaho:

3.1.Sekhomaretsi sa lithaele:

VAE RDP e matlafatsa matla a tlamo le ho tenyetseha ha li-adhesives tsa lithaele, ho fella ka ho eketseha ha matla a tlamo le ho fokotseha ho fokolang.Lintho tsa eona tsa ho boloka metsi li boetse li thusa ho eketsa nako ea ho bula, ho etsa hore lithaele li be bonolo ho li kenya.

3.2.Lisistimi tsa kantle tsa ho kenya lerako le ho qeta (EIFS):

Ho EIFS, VAE RDP e ntlafatsa khanyetso ea sistimi ho putlama le boemo ba leholimo.E ntlafatsa ho khomarela ha primer ho substrate mme e fana ka maemo a bonolo ho amohela katoloso ea mocheso le ho fokotseha.

3.3.Boikoetliso ba ho ikemela:

VAE RDP e ntlafatsa phallo le thepa ea ho ikemela ea liner.E ntlafatsa boreleli ba holim'a metsi 'me e fokotsa ho fokotseha, e fana ka motheo o ts'oanang le o tšoarellang bakeng sa ho koahela fatše.

3.4.Patching mortars:

Litabeng tsa ho lokisa, VAE RDP e matlafatsa matla a tlamo le momahano, e ntlafatsa ho tšoarella le ts'ebetso ea nako e telele ea tokiso.E boetse e thusa ho ntlafatsa ts'ebetso le ho fokotsa ho phunyeletsa, ka hona ho matlafatsa tšireletso ea mongobo.

4. Phello ea VAE RDP mosebetsing oa seretse:

4.1.Matla a ho khomarela:

VAE RDP e ntlafatsa matla a maqhama pakeng tsa seretse le substrate, e leng se etsang hore ho be le kopano e matla, e tšoarellang haholoanyane.E ka theha filimi e tenyetsehang ka segokanyimmediamentsi sa sebolokigolo ho ntlafatsa adhesion tlas'a maemo a fapaneng.

4.2.Ho boloka metsi:

Thepa e bolokang metsi ea VAE RDP e lelefatsa ts'ebetso ea hydration, e bakang pholiso e ntle le ho ntlafatsa thepa ea mochini ea seretse.Sena se netefatsa ts'ebetso e nepahetseng le ho tšoarella ha nako e telele, haholo-holo libakeng tse thata.

4.3.Lintho tsa Rheological:

VAE RDP e ka fetola boitšoaro ba rheological ea seretse, ea ntlafatsa mokelikeli le ho sebetsa.E fokotsa ho arohana le ho tsoa mali ha e ntse e ntlafatsa ho khomarela, e leng se etsang hore ho be bonolo ho sebelisa le ho lokisa holim'a metsi.

Li-powders tsa VAE RDP li bonts'a monyetla o moholo oa ho ntlafatsa ts'ebetso ea lirekere tse fapaneng tsa kaho.Thepa ea eona e ikhethang e thusa ho ntlafatsa matla a tlamahano, ho boloka metsi le boits'oaro ba rheological, ka tsela eo e ntlafatsa metsoako ea seretse le ho ntlafatsa ho tšoarella le ho sebetsa.Ka ho utloisisa ts'ebeliso ea VAE RDP mefuteng e fapaneng ea seretse, litsebi li ka sebelisa melemo ea eona ho fihlela liphetho tse holimo tsa kaho.
