Ko te tikanga whakamatautau mo nga ahuatanga me te poiketanga o te paura polymer redispersible RDP, Ka whakamahia te ao katoa ki te whakamarara i te paura polymer RDP me te vinyl acetate me te ethylene copolymerized emulsion paura, ethylene me te vinyl chloride me te waikawa lauric vinyl ester ternary copolymer paura, vinyl acetate me te ethylene me te ngako pakeke waikawa vinyl ester ternary copolymer paura, enei e toru ki te titaria polymer paura RDP i roto i te mākete rangatira katoa, rawa vinyl acetate me te ethylene copolymer paura VAC / E, Kei te noho te reira i te tūranga ārahi i roto i te mara o te ao, me te tohu i te āhuatanga hangarau o redispersible polymer paura RDP. .
Te paura polymer redispersibleHe tino kaha te here o te RDP, te whakapai ake i te ngawari o te kumete me te roa ake o te wa whakatuwheratanga, hoatu te kumete tino pai mo te parenga kawakore, whakapai ake i te piri o te kumete adhesion, te kaha flexible, te waikore, te kirihou, te mau atete me te hanga, i roto i te moata anti-kapiti ngawari. he kaha ake te ngawari.
Mai i te wheako hangarau o te polymer i whakarerekehia e te kumete, he pai ake te otinga hangarau:
1, Ko te RDP tetahi o nga polymers e tino whakamahia ana i te ao.
2, He wheako tono nui i roto i te waahi o te hoahoanga;
3, ka taea e koe te whakatutuki i nga whakaritenga o nga taonga rheological moata (ara, te hanganga e hiahiatia ana);
4, me etahi atu monomer polymer resin he iti te mea rewa waro (VOC) me nga ahuatanga hau irritant iti;
5, me te pai o te uv resistance me te pai o te wera me te pumau mo te wa roa;
6, ki te ātete saponification tiketike;
7, me te whānuitanga pāmahana karaihe (Tg);
8, me nga hononga matawhānui tino pai, ngawari me nga taonga miihini;
9, he ngawari me te rite te mahi o te whakakotahitanga o te colloid tiaki (polyvinyl alcohol).
Ko te tikanga rapu mo te kaha piri o te paura polymer redispersible RDP e whakaatuhia ana e nga tikanga whakatau e whai ake nei:
1, tuatahi tango redispersible polymer paura RDP 5g ki te kapu ine karaihe, tāpiri 10g wai parakore me te whakaoho mo te 2min, kia rite te konatunatua;
2. Whakatakotoria te kapu ine i konatunatua mo te 3 meneti ka whakaoho ano mo te 2min;
3. pania te otinga katoa i roto i te kapu ine ki runga i te pereti karaihe ma;
4, hoatu te pereti karaihe ki DW100 iti te pāmahana te pouaka whakamātautau whaihanga taiao;
5, i te mutunga ka whakanohoia ki roto i te 0 ° C tikanga whaihanga taiao mo te 1 haora, tangohia te pereti karaihe, whakamatautauhia te tere o te hanga kiriata, kia rite ki te huringa o te hanga kiriata o te redispersible polymer paura RDP i roto i te whakamahi i te kaha hononga paerewa.
