Maitiro ekuyedza upfu hwepolymer hunogona kunyungudika zvakare RDP?

Nzira yekuyedza yekuona hunhu uye viscosity yepolymer powder RDP, Pasi rose inoshandiswa zvakanyanya kuparadzira polymer powder RDP nevinyl acetate uye ethylene copolymerized emulsion powder, ethylene uye vinyl chloride uye lauric acid vinyl ester ternary copolymer powder, vinyl acetate uye ethylene uye senior fatty acid vinyl ester ternary copolymer powder, matatu aya ekuparadzira polymer powder RDP mumusika wese, kunyanya vinyl acetate uye ethylene copolymer powder VAC/E, ine chinzvimbo chepamusoro mumunda wepasi rose uye inomiririra hunhu hwehunyanzvi hwepolymer powder RDP.

Upfu hwepolymer hunonyungudika zvakareRDP ine simba guru rekubatanidza, inovandudza kuchinjika kwedhaka uye ine nguva yakareba yekuvhura, inopa dhaka rekudzivirira alkaline, inovandudza kunamatira kwedhaka, simba reflexural, mvura isingapindi mvura, plasticity, kuramba kupfeka uye kuvaka, uye mune dhaka rinochinjika rinorwisa kutsemuka rine kuchinjika kwakasimba.

Kubva pane zvakaitika pakugadzira polymer yakagadziriswa nemortar, ichiri mhinduro iri nani yehunyanzvi:

1, RDP ndeimwe yemapolymer anoshandiswa zvakanyanya pasi rose.
2, Ruzivo rwakakura mukushandisa mubazi rekuvaka;

3, inogona kusangana nezvinodiwa zve rheological properties yedhaka (ndiko kuti, kuvakwa kunodiwa);

4, pamwe chete nedzimwe monomer polymer resin ine low organic volatile matter (VOC) uye ine low irritant gas hunhu;

5, ine simba rakanaka rekudzivirira kupisa uye kugara kwenguva refu;

6, ine simba guru rekudzivirira saponification;

7, ine tembiricha yakakura yegirazi (Tg);

8, ine kubatana kwakanyatsonaka, kuchinjika uye hunhu hwemakanika;

9, kushanda kuri nyore uye kwakafanana kwemusanganiswa wekudzivirira wecolloid (polyvinyl alcohol).

Nzira yekuona simba rekunamira repolymer powder RDP inonyungudika inoratidzwa nenzira dzinotevera dzekusarudza:

1, tanga watora upfu hwepolymer hunonyungudika hweRDP 5g mukapu yekuyera yegirazi, wedzera 10g yemvura yakachena wobva wakurunga kwemaminitsi maviri, wobva wasanganisa zvakaenzana;

2. Isa kapu yekuyera yakasanganiswa kwemaminitsi matatu wobva wasanganisazve kwemaminitsi maviri;

3. Zadza mushonga wese mukapu yekuyeresa pagirazi rakachena rakatambanudzwa;

4, isa ndiro yegirazi mubhokisi rekuyedza reDW100 rekuyedza tembiricha yakaderera;

5, pakupedzisira yakaiswa mumamiriro ekufananidzira e0°C kweawa imwe chete, bvisa ndiro yegirazi, edza mwero wekuumbwa kwefirimu, zvichienderana nekushandurwa kwehuwandu hwekuumbwa kwefirimu hweRDP inonyungudika zvakare uchishandisa simba rekubatanidza rakajairika.
