E faʻafefea ona suʻeina le paʻu polymer e mafai ona faʻaaogaina RDP?

Suʻega metotia mo meatotino ma le viscosity o redispersible polymer paʻu RDP, I le lalolagi atoa e faʻaaogaina lautele e faʻasalalau polymer paʻu RDP ma vinyl acetate ma ethylene copolymerized emulsion paʻu, ethylene ma vinyl chloride ma lauric acid vinyl ester ternary copolymer paʻu, vinyl acetate ma ethylene ma gaʻo sinia. acid vinyl ester ternary copolymer paʻu, o nei e tolu e faʻasalalau polymer paʻu RDP i le maketi atoa pule, aemaise vinyl acetate ma ethylene copolymer paʻu VAC / E, O loʻo i ai se tulaga maualuga i le lalolagi atoa ma faʻatusalia uiga faʻapitoa o le redispersible polymer paʻu RDP. .

Redispersible polymer pautaO le RDP o loʻo i ai le malosi faʻapitoa, faʻaleleia le fetuutuunai o le sima ma e umi le taimi e tatala ai, tuʻuina atu le paluga sili ona malosi alkaline, faʻaleleia le faʻapipiʻiina o le faʻapipiʻi o le sima, malosi faʻamalosi, leai se vai, palasitika, faʻaofuofu teteʻe ma le fausiaina, i totonu o le paluga faʻafefete faʻafefete. e sili atu ona fetuutuunai.

Mai le poto masani o le polymer ua suia i le sima, o loʻo avea pea ma fofo faʻapitoa sili atu:

1, RDP o se tasi o polymers sili ona faʻaaogaina i le lalolagi.
2, Faʻamatalaga faʻaoga tele i le matata o le tusiata;

3, e mafai ona faʻamalieina manaʻoga o meatotino rheological mortar (o lona uiga, le fausiaina manaʻomia);

4, faʻatasi ai ma isi monomer polymer resin e maualalo mea faʻafefete (VOC) ma uiga kasa irritant maualalo;

5, faʻatasi ai ma le faʻamalosia lelei o le uv ma le lelei o le vevela ma le mautu umi;

6, faʻatasi ai ma le maualuga o le saponification teteʻe;

7, fa'atasi ai ma se va'aiga vevela tioata lautele (Tg);

8, faʻatasi ai ma faʻapipiʻi atoatoa lelei, fetuutuunai ma mea faʻainisinia;

9, faigofie ma tutusa faatinoga o le colloid puipuiga (polyvinyl ava malosi) tuufaatasiga.

O le auala e iloa ai mo le malosi faʻapipiʻi o le redispersible polymer powder RDP o loʻo faʻaalia i metotia faʻamautu nei:

1, ave muamua redispersible polymer powder RDP 5g i totonu o se ipu fua tioata, faaopoopo 10g vai mama ma faʻafefe mo le 2min, faʻafefiloi tutusa;

2. Seti le ipu fua fefiloi mo le 3min ma toe faʻafefe mo le 2min;

3. Ufi uma vaifofo i totonu o le ipu fua i luga o se ipu tioata mama faalava;

4, tuu le ipu tioata i DW100 maualalo vevela siosiomaga simulation pusa suega;

5, mulimuli ane tuʻuina i le 0 ° C tulaga faʻataʻitaʻiga mo le 1 itula, ave i fafo le ipu tioata, faʻataʻitaʻi le fua faʻatulagaina ata, e tusa ai ma le suiga o le faʻatulagaina o ata tifaga o le RDP polymer powder redispersible i le faʻaaogaina o le malosi faʻapipiʻi masani.
