Ko te tikanga whakamātautau mō ngā āhuatanga me te matotoru o te paura pūmua ka taea te whakamarara anō RDP, e whakamahia whānuitia ana puta noa i te ao hei whakamarara i te paura pūmua RDP me te paura whakamomona ethylene copolymerized, te paura ethylene me te vinyl chloride me te paura copolymer ternary waikawa lauric vinyl acetate me te ethylene me te paura copolymer ternary waikawa ngako matua vinyl ester, ko ēnei e toru hei whakamarara i te paura pūmua RDP puta noa i te mākete katoa, inā koa te paura vinyl acetate me te paura copolymer ethylene VAC/E. Kei a rātou te tūranga matua i roto i te mara o te ao, ā, e tohu ana i ngā āhuatanga hangarau o te paura pūmua ka taea te whakamarara anō RDP.
Paura pūmua ka taea te whakamarara anōHe tino kaha te here o te RDP, ka whakapai ake i te ngāwari o te moata, ā, he roa ake te wā whakatuwheratanga, ka pai ake te ātete ki te kawakore o te moata, ka whakapai ake i te piri o te moata, ka kaha te piko, ka ārai wai, ka ngāwari te kirihou, ka ātete ki te kakahu me te hanganga, ā, he kaha ake te ngāwari o te moata ārai-pakaru ngāwari.
Mai i ngā wheako hangarau o te pūhui i whakarerekētia e te moata, he otinga hangarau pai ake tonu tēnei:
1, ko te RDP tētahi o ngā pūmua e whakamahia whānuitia ana i te ao.
2, He wheako tono whānui i roto i te mara o te hoahoanga;
3, ka taea te whakatutuki i ngā whakaritenga o ngā āhuatanga rheological o te moata (arā, ko te hanganga e hiahiatia ana);
4, me ētahi atu monomer polymer kapia he iti te matū mura waro (VOC) me ngā āhuatanga hau whakapataritari iti;
5, he ātete UV pai rawa atu, he ātete wera pai, ā, he pumau mō te wā roa;
6, he ātete nui ki te waikura;
7, me te whānuitanga pāmahana karāhe whānui (Tg);
8, me te hononga whānui, te ngāwari me ngā āhuatanga hangarau tino pai;
9, he ngāwari, he rite hoki te mahi o te huinga colloid tiaki (waipiro polyvinyl).
Ko te tikanga kimi i te kaha piri o te paura pūmua ka taea te whakamarara anō RDP ka tohuhia e ngā tikanga whakatau e whai ake nei:
1, tangohia tuatahi te paura pūmua redispersible RDP 5g ki roto i te kapu ine karāhe, tāpirihia te 10g wai parakore ka whakaoho mō te 2min, kia ōrite te whakaranu;
2. Whakatakotoria te kapu ine i konatunatua mō te 3 meneti, ka whakaoho anō mō te 2 meneti;
3. Pania te wai katoa ki roto i te kapu ine ki runga i tētahi pereti karāhe ma, whakapae;
4, whakanohoia te pereti karāhe ki roto i te pouaka whakamātautau whakaata taiao pāmahana iti DW100;
5, ka whakanohoia ki roto i ngā āhuatanga whakatauira taiao 0°C mō te 1 hāora, ka tangohia te pereti karāhe, ka whakamātau i te tere hanganga kiriata, kia rite ki te huringa tere hanganga kiriata o te paura pūmua redispersible RDP i te whakamahinga o te kaha hononga paerewa.
