Ko te paura pūmua ka taea te whakamarara anō (RDP) he copolymer o te vinyl acetate me te ethylene i hangaia mā te tukanga whakamaroke rehu. He wāhanga matua tēnei i roto i ngā momo mahi hanga, e whakarato ana i te piri pai ake, te ngāwari me te pakari ki ngā hua sima. He maha ngā taahiraa e whai wāhi ana ki te hanga i ngā paura pūmua ka taea te whakamarara anō.
1. Kōwhiringa rauemi mata:
Ko te kopolymer vinyl acetate-ethylene: Ko te rauemi mata matua o te RDP he kopolymer o te vinyl acetate me te ethylene. I whiriwhiria tēnei kopolymer nā ōna āhuatanga piri pai me tōna kaha ki te whakanui ake i te ngāwari me te pakari o ngā rauemi sima.
2. Te whakapūhuitanga o te emulsion:
Ka tīmata te tukanga whakaputa me te whakapūhuitanga emulsion, e whakapūhuitia ai ngā monomers vinyl acetate me te ethylene i te aroaro o ngā kaiwhakaoho me ngā kaiwhakaū.
Ka āta whakahaerea te tukanga whakapūhui emulsion kia whiwhi ai i te taumaha ngota ngota, te hanganga, me te hanganga copolymer e hiahiatia ana.
3. Te tauhohenga me te whakakotahitanga:
Ka tauhohe ngā monomer vinyl acetate me te ethylene i te aroaro o tētahi whakakorikori hei hanga i tētahi copolymer.
He mea nui te tukanga copolymerization hei whiwhi i ngā polymer me ngā āhuatanga e hiahiatia ana, tae atu ki ngā āhuatanga hanga kiriata pai me te kaha ki te horapa anō.
4. Whakamaroke rehu:
Kātahi ka whakamarokehia te emulsion ki roto i tētahi rūma wera, ka mimiti te wai, ka waiho ngā matūriki totoka o te polymer ka taea te whakamaroke anō.
Ka āta whakahaeretia ngā āhuatanga whakamaroke rehu, pērā i te pāmahana me te hau, kia pai ai te hanganga o ngā matūriki paura angiangi e rere noa ana.
5. Te maimoatanga mata:
He maha ngā whakamahinga o ngā maimoatanga mata hei whakapai ake i te pumau o te rokiroki me te ngawari ki te horapa anō o ngā paura polymer.
He maha ngā wā ka whakamahia ngā tāpiringa wai-whakaaro, ngā koroid tiaki rānei, i roto i ngā maimoatanga mata hei ārai i te kohikohinga o ngā matūriki me te whakarei ake i te mararatanga o te paura ki roto i te wai.
6. Te whakahaere kounga:
Ka whakatinanahia ngā tikanga whakahaere kounga tino pakari puta noa i te tukanga hanga. Ka aroturukitia ngā tawhā pēnei i te tohatoha rahi o te matūriki, te kiato papatipu, te ihirangi monomer toenga me te pāmahana whakawhiti karāhe hei whakarite i te ōritetanga o te hua.
7. Tākai:
Ko te paura pūmua ka taea te whakamarara anō ka tākaihia ki roto i ngā ipu ātete-makuku hei ārai i te mimiti wai, ka pā kino pea tēnei ki tōna mahi.
Ngā tono o ngā paura pūmua whakamarara anō:
E whakamahia ana te RDP i roto i te whānuitanga o ngā mahi hanga, tae atu ki ngā piripiri taera, ngā matū whakataurite-ake, ngā pūnaha whakaoti whakamahana o waho (EIFS) me ngā moata sima.
Ka whakarei ake te paura i ngā āhuatanga pēnei i te ātete ki te wai, te ngāwari me te piri, ā, ka āwhina ki te whakapai ake i te mahi whānui me te roa o ēnei rauemi hanga.
hei whakamutunga:
He rauemi maha ngā whakamahinga o te paura pūmua ka taea te whakamarara anō, ā, he mea nui āna whakamahinga i roto i te umanga hanga. Ko tōna whakaputanga he kowhiringa tupato o ngā rauemi mata, te whakapūmuatanga emulsion, te whakamaroke rehu, te maimoatanga mata me ngā tikanga whakahaere kounga tino pakari.
He tukanga uaua te hanga paura polymer ka taea te whakamarara anō, e hiahia ana ki te tika me te aro ki ngā taipitopito kia whiwhi ai i tētahi hua kounga teitei me ngā āhuatanga e hiahiatia ana mō ngā tono hangahanga.
