Mokhoa oa ts'ebetso oa Redispersible Polymer Powder (RDP) ka seretse se omileng

Redispersible Polymer Powder(RDP)ke tlatsetso ea bohlokoa mefuteng ea seretse se omeletseng, e fanang ka melemo e mengata joalo ka ho khomarela hantle, momahano, ho tenyetseha le ho sebetsa. Mokhoa oa eona oa ts'ebetso o kenyelletsa mekhahlelo e mengata, ho tloha ho hasana ka metsing ho ea ho sebelisana le likarolo tse ling ka har'a motsoako oa seretse. A re ke re hlahlobeng mokhoa o qaqileng:

Phasano ka Metsing:
Likaroloana tsa RDP li etselitsoe ho hasana ka potlako le ka mokhoa o ts'oanang metsing ka lebaka la tlhaho ea tsona ea hydrophilic. Holim'a metsi ho motsoako o omileng oa seretse, likaroloana tsena lia ruruha le ho hasana, li etsa ho fanyeha ho tsitsitseng ha colloidal. Ts'ebetso ena ea ho hasana e pepesa sebaka se seholo sa polymer ho tikoloho e potolohileng, ho nolofatsa litšebelisano tse latelang.

Tlhahiso ea lifilimi:
Ha metsi a ntse a tsoela pele ho kenngoa ka har'a motsoako oa seretse, likaroloana tsa RDP tse qhalakaneng li qala ho phalla, ho etsa filimi e tsoelang pele ho pota-potile likaroloana tsa cementitious le likarolo tse ling. Filimi ena e sebetsa e le tšitiso, e thibela ho kopana ka ho toba pakeng tsa lisebelisoa tsa cementitious le mongobo o ka ntle. Sena se bohlokoa bakeng sa ho fokotsa ho kenella ha metsi, ho matlafatsa nako e telele, le ho fokotsa kotsi ea efflorescence le mefuta e meng ea ho senyeha.

Kamano e Matlafalitsoeng le Momahano:
Filimi ea polymer e entsoeng ke RDP e sebetsa e le moemeli oa tlamahano, e khothalletsang ho khomarela pakeng tsa seretse le likaroloana tse sa tšoaneng tse kang konkreite, masonry kapa lithaele. Filimi e boetse e ntlafatsa momahano ka har'a matrix a seretse ka ho koala likheo pakeng tsa likaroloana, kahoo ho matlafatsa matla a kakaretso le botšepehi ba seretse se thata.

Flexibility le Crack Resistance:
O mong oa melemo ea bohlokoa ea RDP ke bokhoni ba eona ba ho fana ka maemo a bonolo ho matrix a seretse. Filimi ea polymer e amohela metsamao e nyane ea substrate le ho atolosoa ha mocheso, ho fokotsa kotsi ea ho phatloha. Ho feta moo, DPP e ntlafatsa matla le ho tsitsa ha seretse, ho ntlafatsa ho hanyetsa ha eona ho robeha tlas'a meroalo e tsitsitseng le e matla.

Paballo ea Metsi:
Boteng ba RDP ka har'a motsoako oa seretse se thusa ho laola ho bolokoa ha metsi, ho thibela ho fetoha mouoane ka potlako nakong ea pele ea phekolo. Nako ena e atolositsoeng ea hydration e khothalletsa hydration e feletseng ea samente 'me e tiisa tsoelo-pele e nepahetseng ea thepa ea mechine, e kang matla a khatello le a flexural. Ho feta moo, ho boloka metsi a laoloang ho kenya letsoho ho ntlafatseng ts'ebetso le nako e telele e bulehileng, ho nolofatsa ts'ebeliso e bonolo le ho phethoa ha seretse.

Ntlafatso ea ho tšoarella:
Ka ho ntlafatsa ho khomarela, ho tenyetseha, le ho hanyetsa ho phunyeha, DPP e ntlafatsa haholo ho tšoarella ha lisebelisoa tsa seretse se omileng. Filimi ea polymer e sebetsa e le tšitiso e sireletsang khahlanong le ho kenella ha mongobo, litlhaselo tsa lik'hemik'hale, le litšila tse silafatsang tikoloho, ka tsela eo e lelefatsa bophelo ba tšebeletso ea seretse le ho fokotsa litlhoko tsa tlhokomelo.

Ho lumellana le Additives:
RDPe bonts'a tšebelisano e ntle haholo le li-additives tse fapaneng tse atisang ho sebelisoa ha ho etsoa seretse se omeletseng, joalo ka li-intrainer tsa moea, li-accelerator, li-retarders le li-pigments. Mokhoa ona oa ho feto-fetoha o lumella ho etsoa ha thepa ea seretse ho fihlela litlhoko tse khethehileng tsa ts'ebetso bakeng sa lits'ebetso tse fapaneng le maemo a tikoloho.

mokhoa oa ts'ebetso ea phofo ea polymer e qhalakaneng ka seretse se omeletseng e kenyelletsa ho hasana ka metsing, sebopeho sa filimi, ho khomarela ho matlafatsa le ho momahano, ho feto-fetoha ha maemo le ho hanyetsa ho phatloha, ho boloka metsi, ho matlafatsa nako e telele, le ho lumellana le li-additives. Liphello tsena tse kopantsoeng li kenya letsoho mosebetsing o ntlafetseng, ho sebetsa, le ho tšoarella ha litsamaiso tsa seretse se omeletseng ho pholletsa le mefuta e mengata ea kaho.
