Kedu ka esi nwalee polymer powder RDP redispersible?

Ule usoro maka Njirimara na viscosity nke redispersible polymer ntụ ntụ RDP, n'ụwa nile na-ọtụtụ ebe na-achụsasị polymer ntụ ntụ RDP na vinyl acetate na ethylene copolymerized emulsion ntụ ntụ, ethylene na vinyl chloride na lauric acid vinyl ester ternary copolymer ntụ ntụ, vinyl acetate na ethylene abụba na agadi. acid vinyl ester ternary copolymer ntụ ntụ, atọ ndị a iji chụsaa polymer powder RDP n'ahịa niile na-achị, ọkachasị vinyl acetate na ethylene copolymer ntụ ntụ VAC / E, Ọ na-enwe ọnọdụ isi na mpaghara ụwa ma na-anọchite anya njirimara teknụzụ nke polymer powder RDP. .

Polima ntụ ntụ na-agbanwe agbanweRDP nwere ike njikọ pụtara ìhè, melite mgbanwe nke ngwa agha ma nwee ogologo oge mmeghe, nye ngwa agha alkaline nguzogide dị mma, meziwanye adhesion nke ngwa agha adhesion, ike na-agbanwe agbanwe, mgbochi mmiri, plasticity, na-eyi nguzogide na ihe owuwu, na ngwa agha mgbochi na-agbanwe agbanwe. nwere mgbanwe siri ike karị.

Site na ahụmịhe teknụzụ nke polymer gbanwere site na ngwa agha, ọ ka bụ azịza teknụzụ ka mma:

1, RDP bụ otu n'ime polymer ndị a na-ejikarị eme ihe n'ụwa.
2, Ahụmahụ ngwa ngwa dị ukwuu n'ọhịa nke ije;

3, nwere ike izute ihe ndị chọrọ nke ngwa agha rheological Njirimara (ya bụ, ihe owuwu achọrọ);

4, na ndị ọzọ monomer polymer resin nwere ala organic agbanwe agbanwe (VOC) na ala mgbakasị gas àgwà;

5, nke nwere oke nguzogide uv na ezigbo nguzogide okpomọkụ na nkwụsi ike ogologo oge;

6, na nguzogide saponification dị elu;

7, nke nwere nnukwu iko okpomọkụ (Tg);

8, nwere njikọ dị oke mma zuru oke, mgbanwe na akụrụngwa akụrụngwa;

9, arụmọrụ dị mfe na nke yiri ya nke ngwakọta colloid (polyvinyl alcohol).

Usoro nchọpụta maka ike nrapado nke polymer powder RDP na-eji usoro mkpebi ndị a mara:

1, buru ụzọ were redispersible polymer powder RDP 5g n'ime iko iko, tinye 10g mmiri dị ọcha ma kpalie maka 2min, mee ka ọ gwakọta ya;

2. Tọọ iko agwakọta maka nkeji 3 ma kpalie ọzọ maka nkeji 2;

3. Ghichaa ihe ngwọta niile n'ime iko nha na efere iko dị ọcha kwụ ọtọ;

4, tinye iko efere n'ime DW100 ala okpomọkụ gburugburu ebe obibi simulation igbe ule;

5, n'ikpeazụ etinye na 0 Celsius C simulation gburugburu ebe obibi maka 1 hour, wepụ iko iko, nwalee ihe nkiri e guzobere ọnụego, dị ka film e guzobere ọnụego mgbanwe nke redispersible polymer powder RDP na ojiji nke ọkọlọtọ bonding ike.
