Paura Pūmua Whakamarara Anō (RDP)He matū paura te mea i hangaia mā te whakamaroke i te whakaemulsion polymer, e whakamahia whānuitia ana i roto i ngā rauemi pēnei i te hanga, ngā paninga, ngā piripiri, me ngā piripiri taera. Ko tana mahi matua he marara anō ki roto i te whakaemulsion mā te tāpiri wai, kia pai ai te piri, te ngāwari, te ātete ki te wai, te ātete ki te pakaru, me te ātete ki te huarere.
Ka taea te tātari i te hanganga o te Paura Pūmua Whakamarara Anō (RDP) mai i ngā āhuatanga maha, tae atu ki ngā wāhanga e whai ake nei:
1. Kapia polima
Ko te wāhanga matua o te Paura Pūmua Whakamarara Anō ko te kapia pūmua, he pūmua i te nuinga o te wā ka whiwhihia mā te whakapūmuatanga emulsion. Ko ngā kapia pūmua noa ko:
Waipiro polyvinyl (PVA): he pai te piri me ngā āhuatanga hanga kiriata, ā, e whakamahia whānuitia ana i roto i ngā rauemi hanga.
Ko ngā polyacrylates (pērā i ngā polyacrylates, ngā polyurethanes, me ētahi atu): he tino ngāwari, he kaha piri, he ātete wai hoki.
Ko te Polystyrene (PS) te ethylene-vinyl acetate copolymer rānei (EVA): e whakamahia whānuitia ana hei whakapai ake i ngā āhuatanga hanga kiriata, hei ātete ki te wai, hei ātete hoki ki te huarere.
Polymethyl methacrylate (PMMA): He pai te ārai-pakeketanga me te mārama o tēnei polymer.
Ka hangaia e ēnei kapia pūmua he whakapūhui mā roto i ngā tauhohenga whakapūhui, kātahi ka tangohia te wai i roto i te whakapūhui mā te whakamaroke rehu, mā te whakamaroke tio rānei, ā, hei whakamutunga, ka puta he Paura Pūmua Whakarewa-anō (RDP) i roto i te āhua paura.
2. Ngā matū horoi
Hei pupuri i te pumau i waenga i ngā matūriki polymer, me te karo i te kohikohi i roto i te paura, ka tāpirihia he nui o ngā surfactants e tika ana i te wā o te tukanga whakaputa. Ko te mahi a ngā surfactants he whakaiti i te taumahatanga mata i waenga i ngā matūriki, me te āwhina i ngā matūriki kia marara ki roto i te wai. Ko ngā surfactants noa ko:
Ngā matū horoi kore-ionic (pērā i ngā polyethers, polyethylene glycols, me ētahi atu).
Ngā matū horoi anionic (pērā i ngā tote waikawa ngako, ngā alkyl sulfonates, me ētahi atu).
Ka taea e ēnei matū horoi te whakarei ake i te mararatanga o te Paura Pūmua Marara Anō (RDP), e āhei ai te paura rapa ki te hanga anō i tētahi emulsion i muri i te tāpiri i te wai.
3. Ngā whakakī me ngā whakamātotoru
Hei whakatikatika i te mahi a ngā paura rapa me te whakaiti i ngā utu, ka tāpirihia pea ētahi whakakī me ngā whakamātotoru i te wā e hangaia ana. He maha ngā momo whakakī, ā, ko ngā mea noa ko:
Konupūmā kāponāte: he whakakī kore-waro e whakamahia whānuitia ana hei whakanui ake i te piri me te whakapai ake i te whai huatanga o te utu.
Tarukino: ka taea te whakanui ake i te rere me te ātete ki te pakaru o te rauemi.
Ka taea e ngā kohuke silicate: pērā i te bentonite, te graphite whānui, me ētahi atu, te whakapakari i te ātete ki te pakaru me te ātete wai o te rauemi.
Ko ngā mea whakamātotoru e whakamahia ana hei whakarerekē i te matotoru o te hua kia urutau ai ki ngā āhuatanga hanga rerekē. Ko ngā mea whakamātotoru noa ko te hydroxypropyl methylcellulose (HPMC) me te polyvinyl alcohol (PVA).
4. Ārai-whakapiripiri
I roto i ngā hua paura, hei ārai i te kohikohinga i te wā e rongoatia ana, e kawetia ana rānei, ka taea hoki te tāpiri i ngā mea ārai-whakakorikori i te wā e hangaia ana. Ko ngā mea ārai-whakakorikori he matū kore-ora pai, pērā i te silicate konumohe, te hauhā silicon, me ētahi atu. Ka taea e ēnei matū te hanga i tētahi kiriata tiaki i runga i te mata o ngā matūriki paura rapa hei ārai i te kohikohinga o ngā matūriki.
5. Ētahi atu tāpiringa
Tērā pea kei roto i te Paura Pūmua Whakamarara Anō (RDP) ētahi tāpiri motuhake hei whakapai ake i ngā āhuatanga motuhake:
Ātete ki ngā hihi UV: ka whakapai ake i te ātete huarere me te kaha ārai-pakeke o te rauemi.
Kaihoko paturopi: ka whakaiti i te tipu o ngā moroiti, inā koa ka whakamahia i roto i te taiao makuku.
Kaiwhakaahua: ka whakapai ake i te ngāwari me te ātete ki te pakaru o te paura rapa.
Ārai Hukapapa: Ārai i te hukapapa o ngā rauemi i ngā taiao pāmahana iti, ka pā ki ngā pānga hanga me te whakamahinga.
6. Makuku
Ahakoa kei roto te Paura Pūmua Whakamarara Anō (RDP) i te āhua o te paura maroke, me whakahaere anō hoki te makuku i te wā e hangaia ana, ā, ko te nui o te makuku ka whakahaeretia i raro i te 1%. Mā te nui o te makuku e tika ana ka āwhina i te pupuri i te rere me te pumau mō te wā roa o te paura.
Te tūranga me te mahi a te Paura Pūmua Whakamarara Anō (RDP)
Ko te mahi matua a te Paura Pūmua Whakamarara Anō (RDP) ko tōna taea te whakamarara anō hei hanga i tētahi emulsion i muri i te tāpiri wai, ā, ko ēnei ngā āhuatanga mahi nui e whai ake nei:
Te piri pai: Ka whakarei ake i te kaha piri o ngā paninga me ngā piripiri, ā, ka whakapai ake i te kaha piri i waenga i ngā rauemi hanga.
Te ngāwari me te ngāwari: Ka whakapai ake i te ngāwari o te paninga, ka whakanui ake i tōna ātete ki te pakaru me te ātete ki te pānga.
Ātete wai: Whakapai ake i te ātete wai o te rauemi, he pai mō te whakamahi i waho, i ngā taiao makuku rānei.
Ātete ki te huarere: Whakapai ake i te ātete UV, te ārai-pakeketanga me ētahi atu āhuatanga o te rauemi, ā, ka roa ake tōna ora mahi.
Ātete pakaru: He pai te ātete pakaru, ā, he pai mō ngā kaupapa hangahanga.
RDPMā te huri i te pūhui whakapūhui ki te paura mā te tukanga matatau, ka hangaia. He maha ngā āhuatanga tino pai, ā, e whakamahia whānuitia ana i roto i te hanganga, i ngā paninga, i ngā piripiri me ētahi atu mara. Ko te kōwhiringa me te ōwehenga o ōna kai ka pā tika ki tōna mahi whakamutunga.
