Nzira yekuyedza redispersible polymer poda RDP?

Nzira yekuyedza yezvivakwa uye viscosity yezve inodispersible polymer poda RDP, Pasi rose inoshandiswa zvakanyanya kuparadzira polymer poda RDP ine vinyl acetate uye ethylene copolymerized emulsion poda, ethylene uye vinyl chloride uye lauric acid vinyl ester ternary copolymer poda, vinyllene acetate uye ethylene acetate uye mukuru mafuta. asidhi vinyl ester ternary copolymer hupfu, idzi nhatu dzekuparadzira polymer hupfu RDP mumusika wese inotonga, kunyanya vinyl acetate uye ethylene copolymer hupfu VAC/E, Inotora chinzvimbo chinotungamira mumunda wepasi rose uye inomiririra hunyanzvi hwekuita redispersible polymer poda RDP. .

Redispersible polymer hupfuRDP ine simba rakatanhamara rechisungo, inonatsiridza kuchinjika kwedhaka uye ine nguva yakareba yekuvhura, inopa dhaka zvakanakisa alkaline kuramba, kuvandudza kunamatira kwedhaka kunamatira, kusimba kwesimba, kusapinda kwemvura, plastiki, kupfeka kuramba uye kuvaka, mune inochinjika anti-crack mortar. ine kuchinjika kwakasimba.

Kubva pahunyanzvi ruzivo rwepolymer yakagadziridzwa nedhaka, ichiri iri nani tekinoroji mhinduro:

1, RDP ndeimwe yemapolima anonyanya kushandiswa munyika.
2, Yakawedzera ruzivo rwekushandisa mumunda wezvivakwa;

3, inogona kusangana nezvinodiwa zvedhaka rheological properties (kureva, inodiwa kuvaka);

4, ine imwe monomer polymer resin ine yakaderera organic volatile nyaya (VOC) uye yakaderera inogumbura gasi maitiro;

5, ine yakanakisa uv kuramba uye yakanaka kupisa kupisa uye kugadzikana kwenguva refu;

6, ine yakakwira saponification kuramba;

7, ine yakafara girazi tembiricha renji (Tg);

8, iine yakanyatso kurongeka kubatanidza, kuchinjika uye michina zvivakwa;

9, iri nyore uye yakafanana kuita kweiyo inodzivirira colloid (polyvinyl doro) musanganiswa.

Iyo nzira yekuona yekunamira simba redispersible polymer poda RDP inoratidzirwa neanotevera ekutsunga nzira:

1, tanga watora redispersible polymer poda RDP 5g mukapu yekuyeresa girazi, wedzera 10g mvura yakachena uye simbisa kwe2min, ita kuti isanganiswe zvakaenzana;

2. Isai mukombe wekuyeresa wakavhenganiswa 3min uye simbisa zvakare 2min;

3. Smira mushonga wose mukapu yekuyeresa pandiro yegirazi yakachena yakachinjika;

4, isa ndiro yegirazi muDW100 yakaderera tembiricha nharaunda simulation test box;

5, yakazoiswa mu 0 ° C yemamiriro ekuenzanisa kwezvakatipoteredza kweawa imwe, tora ndiro yegirazi, edza chiyero chekugadzira firimu, maererano nefirimu yekugadzira chiyero chekushandura redispersible polymer powder RDP mukushandiswa kwesimba rekubatanidza.
