Te tono opaura rapa ka taea te whakamarara anō (RDP) Kua arohia te whakamahinga o ngā paura putty i roto i te umanga hanga me ngā rauemi hanga whare nā tōna pānga nui ki ngā āhuatanga o te hua whakamutunga. Ko ngā paura rapa redispersible he paura polymer e taea ai te hanga marara ina konatunatua ki te wai. Ka whakawhiwhia e ēnei marara he maha ngā āhuatanga pai ki te putty, tae atu ki te whakapai ake i te piri, te ngāwari, te ātete ki te wai, me te mea nui, te tukanga whakapakeke.
Te Mārama ki te Paura Putty me te Paura Latex Whakamarara Anō
He paura pai te paura putty e whakamahia ana mō te whakakī i ngā āputa, te whakangawari i ngā mata, me te whakarite i ngā papa mō te peita, mō ētahi atu whakaotinga rānei. Ko te hanganga taketake o te paura putty he mea here (hei tauira, te sima, te gypsum), ngā whakakī (hei tauira, te talc, te konupūmā kāponāte), me ngā tāpiringa (hei tauira, ngā mea whakaroa, ngā mea whakateretere) e whakahaere ana i ōna āhuatanga mahi. Ina konatunatua ki te wai, ka hangaia e te paura putty he whakapiri ka whakapakeke i roto i te wā, ka hanga he mata pakari, maeneene.
Ko te paura rapa ka taea te whakamarara anō (RDP) he paura pūmua wairewa-wai i hangaia mā te whakamaroke i ngā whakamarara wai o ngā whakamomona pūmua. Ko ngā pūmua noa e whakamahia ana i roto i te RDP ko te styrene-butadiene (SBR), te kiriaku, me te vinyl acetate-ethylene (VAE). Mā te tāpiri o te RDP ki te paura putty ka whakarei ake i ngā āhuatanga ā-tinana me ngā āhuatanga ā-pūkaha o te putty kua rongoatia, mā te whakapai ake i te kaha o te here, te ngāwari, me te ātete ki te pakaru.
Te whakapakeketanga o te paura putty
Ka whakapakeketia te paura putty i te wā e pāngia ana ngā wāhanga here (pērā i te sima, i te gypsum rānei) e te tauhohenga matū ki te wai. Ko te tikanga o te tukanga ko te whakamakuku (mō ngā putty sima) ko te whakatiotanga rānei (mō ngā putty gypsum), ā, ka hua ake ko te hanganga o ngā āhua totoka ka whakapakeketia i roto i te wā. Heoi, ka taea te awe i tēnei tukanga e te maha o ngā āhuatanga, pērā i te aroaro o ngā tāpiringa, te haumākū, te pāmahana, me te hanganga o te putty tonu.
Ko te mahi a te RDP i roto i tēnei tukanga whakapakeketanga he whakarei ake i te hononga i waenga i ngā matūriki, te whakapai ake i te ngāwari, me te whakahaere i te mimiti o te wai. Ko te mahi a te RDP he here, ina marara anō ki roto i te wai, ka hanga he whatunga pūmua i roto i te putty. Ka āwhina tēnei whatunga ki te hopu i ngā ngota wai kia roa ake, ka whakaroa i te tere o te mimiti, ā, ka roa ake te wā mahi o te putty. Hei tāpiri, ka āwhina te whatunga pūmua ki te hanga i tētahi papatipu whakapakeke kaha ake, piripono ake mā te whakapai ake i te taunekeneke matūriki.
Te Pānga o te Paura Latex Whakamarara Anō ki te Tukanga Whakamārō
Te Whakapai Ake i te Āhua Mahi me te Wā Tuwhera:
Mā te whakaurunga o te RDP ki roto i ngā whakatakotoranga putty ka pai ake te mahi mā te whakaroa i te tukanga whakamaroke, ka roa ake te wā mō te tono. He tino whai hua tēnei mō ngā kaupapa nunui me horahia te putty ki ngā wāhi whānui i mua i te whakatō.
Te Ngāwari o te Whakanuia:
Ko tētahi o ngā hua nui o te tāpiri RDP ko te whakapai ake i te ngāwari. Ahakoa he pakarukaru te putty tuku iho i te wā e whakapakeketia ana, ka whai wāhi te RDP ki te hanga i tētahi rauemi ngāwari ake, ka whakaiti i te tūponotanga o te pakaru i raro i te ahotea, i ngā huringa pāmahana rānei.
Te Kaha me te Pūmau:
He nui ake te kaha pēhi me te ātete ki te pakaru o ngā putty kua whakarerekētia e te RDP, ki te whakatauritea ki ngā hanganga kāore i whakarerekētia. Nā te hanganga o tētahi hanganga polymer tēnei e whakakaha ana i te hanganga o te putty kua whakapakeketia.
Te Whakaiti i te Whakaiti:
Ko te whatunga pūmua i hangaia e te paura rapa ka taea te whakamarara anō ka āwhina i te whakaiti i te mimiti i te wā e whakamaroke ana. He mea nui tēnei hei ārai i te hanganga o ngā kapiti, ka pā kino ki te mahi me te ataahua o te putty.
Ātete Wai:
Ko te paura putty i konatunatua ki te paura rapa ka taea te whakamarara anō he ātete ake ki te wai. Ka hangaia e ngā matūriki rapa he paparanga waikore i roto i te putty, ka kore e mimiti te hua kua rongoatia ki te wai, ā, he pai ake mō ngā mahi o waho.
Mā te whakauru i te paura rapa ka taea te whakamarara anō ki roto i ngā hanganga putty ka tino whakarei ake i ōna āhuatanga, inā koa i te wā e whakapakeke ana. Ko ngā painga matua o te RDP ko te whakapai ake i te mahi, te whakarei ake i te ngāwari, te whakanui ake i te kaha me te roa, te whakaiti i te whakahekenga, me te ātete pai ake i te wai. Mā ēnei whakapainga ka pai ake ngā putty kua whakarerekētia e te RDP mō ngā tono o roto me waho, ka roa ake te ora me te mahi i raro i ngā āhuatanga taiao rerekē.
Mō ngā tohunga hanga me ngā kaihanga, te whakamahinga opaura rapa ka taea te whakamarara anō He huarahi māmā engari he huarahi whai hua hei whakapai ake i ngā āhuatanga o ngā paura putty tuku iho, ka hua ake he hua e māmā ake ana te tono, he roa ake te mau, ā, he iti ake te ngatata, te mimiti rānei i te roanga o te wā. Mā te arotau i te whakatakotoranga me te RDP, ka nui ake te whakamahinga o ngā paura putty, me te whakapai ake i te mahi whānui e pā ana ki te piri, te pakeke, me te ātete ki ngā āhuatanga o te rangi.
