He rauemi turanga te putty e whakamahia whānuitia ana i roto i ngā kaupapa whakapaipai whare, ā, ko tōna kounga ka pā tika ki te roa o te mahi me te pānga whakapaipai o te paninga pakitara. Ko te kaha o te piri me te ātete wai he tohu nui hei aromatawai i te mahi a te putty.Paura rapa ka taea te whakamarara anō, hei rauemi pūmua waro kua whakarerekētia, he mea nui tana mahi ki te whakapai ake i te mahi a te putty.
1. Te tikanga mahi a te paura rapa ka taea te whakamarara anō
Ko te paura rapa ka taea te whakamarara anō he paura i hangaia mā te whakamaroke i te whakamomona polymer. Ka taea e ia te whakamomona anō hei hanga i tētahi pūnaha whakamarara polymer pumau i muri i te pā ki te wai, e whai wāhi ana ki te whakapakari i te kaha piri me te ngāwari o te putty. Ko ōna mahi matua ko:
Te whakapai ake i te kaha o te here: Ka hangaia e te paura rapa ka taea te whakamarara anō he kiriata polymer i te wā e whakamaroke ana i te putty, ā, ka mahi tahi me ngā rauemi whakapūkara kore-waro hei whakapai ake i te kaha here ā-kanohi.
Te whakapakari i te ātete wai: Ka hangaia e te paura rapa he whatunga wai-whakaaro i roto i te hanganga putty, ka whakaiti i te urunga wai me te whakapai ake i te ātete wai.
Te whakapai ake i te ngāwari: Ka taea e ia te whakaiti i te pakarukaru o te putty, te whakapai ake i te kaha ki te whakarerekē, me te whakaiti i te tūponotanga o ngā kapiti.
2. Rangahau whakamātautau
Ngā rauemi whakamātautau
Rauemi turanga: paura putty sima-hangai
Paura rapa ka taea te whakamarara anō: paura rapa copolymer ethylene-vinyl acetate (EVA)
Ētahi atu tāpiringa: te whakamātotoru, te kaihoko pupuri wai, te whakakī, me ētahi atu.
Tikanga whakamātautau
I whakaritea ngā pātītī me ngā horopeta paura rapa ka taea te whakamarara anō (0%, 2%, 5%, 8%, 10%), ā, i whakamatautauria te kaha piri me te ātete wai. I whakatauhia te kaha piri mā te whakamātautau hutia, ā, i aromatawaitia te whakamātautau ātete wai mā te tere pupuri kaha i muri i te rumakina ki te wai mō ngā haora 24.
3. Ngā hua me te kōrero
Te pānga o te paura rapa ka taea te whakamarara anō ki te kaha o te piri
E whakaatu ana ngā hua o te whakamātautau, me te pikinga ake o te horopeta RDP, ka whakaatu te kaha here o te putty i te ia o te whakanui ake i te tuatahi, kātahi ka whakau.
Ina piki te horopeta RDP mai i te 0% ki te 5%, ka tino pai ake te kaha here o te putty, nā te mea ka whakarei ake te kiriata polymer i hangaia e te RDP i te kaha here i waenga i te rauemi turanga me te putty.
Ki te whakanuia tonutia te RDP ki te neke atu i te 8%, ka noho papatahi te tipu o te kaha here, ā, ka heke paku noa iho i te 10%, nā te mea pea ka pā te nui rawa o te RDP ki te hanganga mārō o te putty, ka whakaiti i te kaha o te atanga.
Te pānga o te paura rapa ka taea te whakamarara anō ki te ātete wai
E whakaatu ana ngā hua o te whakamātautau ātete wai he pānga nui tō te nui o te RDP ki te ātete wai o te putty.
I tino heke te kaha o te piri o te putty kāore he RDP i muri i te rumakina ki te wai, e whakaatu ana i te ātete wai ngoikore.
Mā te tāpiri i te nui o te RDP e tika ana (5%-8%) ka hanga te putty hei hanganga matū waro-kore matū kikī, ka whakapai ake i te ātete ki te wai, ā, ka tino whakapai ake i te tere pupuri kaha i muri i te 24 hāora o te rumakina.
Heoi, ina neke atu te ihirangi RDP i te 8%, ka heke te ātete wai, nā te nui rawa pea o ngā wāhanga waro ka whakaiti i te kaha ārai-wai o te putty.
Ko ngā whakatau e whai ake nei ka taea te tango mai i ngā rangahau whakamātautau:
He nui e tika anapaura rapa ka taea te whakamarara anō(5%-8%) ka tino whakapai ake i te kaha piri me te ātete wai o te putty.
Mā te nui rawa o te whakamahinga o te RDP (>8%) ka pā ki te hanganga mārō o te putty, ka puhoi, ka heke rānei te kaha o te piri me te ātete ki te wai.
Me arotau te horopeta tino pai kia rite ki te whakamahinga motuhake o te putty kia tutuki ai te taurite pai i waenga i te mahi me te utu.
