He rauemi hanga motuhake te whakakī kōhatu e whakamahia ana hei whakakī i ngā āputa kōhatu, hei whakapai ake i ngā āhuatanga whakapaipai me te pumau o te hanganga, ā, me pai te piri, te ātete ki ngā pakaru, te ātete ki te huarere me te ātete ki te wai.Paura pūmua ka taea te whakamarara anō (RDP)he wāhanga nui kua whakarerekētia i roto i te tauira whakakī kōhatu, ka taea te whakapai ake i te mahi a te rauemi whakakī, kia pai ake ai te mau me te wheako hanga i roto i ngā kaupapa o roto, o waho hoki.
1. Ngā āhuatanga taketake me te tikanga mahi a te RDP
Ko te RDP he paura pūmua ka taea te whakamaroke anō i hangaia mā te whakamaroke rehu. Ko ngā rauemi turanga noa ko te ethylene-vinyl acetate (EVA), te acrylate copolymer me te styrene-acrylate copolymer. Ka taea te whakamaroke anō i te RDP hei hanga i te emulsion pūmua ina tūtaki ki te wai, ā, ka hanga he kiriata pūmua whatunga me ngā hua whakamakuku sima, ngā whakakī rānei hei whakarei ake i te ngāwari me te kaha here whānui o te rauemi grouting. I roto i te grouting kōhatu, ka taea e tēnei kiriata pūmua te hanga i tētahi "piriti piri" ki runga i te mata o te kōhatu, hei ātete pai i te kukū o te ahotea i puta mai i te whakawhānui me te whakaheke wera, me te whakaiti i te tūponotanga o te pakaru.
2. Whakapai ake i te ātete piri me te pakaru
Ko te whakakī kōhatu te tikanga e whakamahia ana hei whakakī i ngā āputa i roto i te kōhatu maori, te māpere, te karāneti me ētahi atu rauemi. He matotoru ngā mata o ēnei papa, ā, he iti te mimiti wai, ā, he iti noa te piri ki te moata sima noa. I muri i te tāpiri i te RDP, ka whakapai ake te kiriata pūmua ngāwari i hangaia i roto i te rauemi whakakī i te piri ki te papa kōhatu, ā, ka taea te pupuri i te hononga pai ahakoa i roto i te taiao he nui te rerekētanga pāmahana, ka ārai i te pakaru me te hinga. I taua wā anō, ka hoatu e te RDP he ngāwari ki te rauemi whakakī, ka taea te whakaiti i ngā pakaru i puta mai i te whakahekenga, i ngā kaha o waho rānei i runga i te atanga kōhatu.
3. Whakapai ake i te ātete wai me te ātete kore e uru ki roto
Ka ngāwari te mā, te poka, te taka rānei o ngā rauemi whakakī kōhatu ina roa te wā e noho ana ki te taiao haukū. Ka taea e te kiriata pūmua waro matotoru i hangaia e te RDP i roto i te pūnaha whakakī te whakaiti i ngā pūwero capillary, te whakapai ake i te ātete wai o te rauemi me te ātete ki te wai, ā, ka ārai i te makuku kei uru ki roto i te kōhatu. He mea nui tēnei mō te whakakī kōhatu i ngā wāhi mākū, i ngā wāhi kua kitea rānei pērā i ngā kaukau, ngā kīhini me ngā whenua o waho.
4. Whakapai ake i te mahi hanga
Mā te whakaurunga o te RDP, ehara i te mea ka arotau noa i ngā āhuatanga ā-pūkaha o te rauemi whakakī kua oti, engari ka whakapai ake hoki i tōna wheako hanga. Ka taea e te RDP te whakapai ake i te pupuri wai o te paru me te ārai i ngā kapiti mimiti i puta mai i te ngaronga o te wai i te wā tōmua; i te wā anō, ka whakapai ake i te mahi me te rere, ka māmā ake te whakakī a te whakakī i ngā kapiti angiangi me te whakatutuki i te mata maeneene me te papatahi. He māmā ake te horoi i te mata paru i muri i te hanganga, ka whakaiti i te tūponotanga o te poke o te mata kōhatu.
5. Whakapai ake i te ātete ki te huarere me te ataahua
Mō te whakakī kōhatu o waho, ko te ātete ki te koroheketanga UV me te ātete ki te huka-rewa he tohu nui mō te ine i te mahi roa. Ka hoatu e te RDP ki te rauemi whakakī he ātete huarere pai rawa atu, ā, ka taea te pupuri i tētahi hanganga pumau i raro i ngā taiao pāmahana teitei me te iti me te huringa makuku-maroke. Hei tāpiri, ko te ngāwari teitei o te RDP ka taea te whakaiti i te rerekētanga tae, te kiri rānei i puta mai i te ahotea taiao, ā, ka roa ake te ataahua o te mata kōhatu.
6. Te horopeta RDP me te arotautanga tātai
Me whakatau te nui o te RDP i roto i te rauemi whakakī kōhatu i runga i ngā āhuatanga pēnei i te momo papa, te whānui o te hononga, me te taiao hanga, ā, ko te tikanga he 2% ki te 6% o te taumaha o te rauemi sima. Mēnā he nui rawa te horopeta, ka piki ake te whakahekenga me te piki ake o ngā utu, engari mēnā he iti rawa te horopeta, kāore pea e tutuki te mahi e tumanakohia ana. Nō reira, i roto i te hanga tuturu, me arotau te tauira mā roto i ngā whakamātautau me te whakarerekē i te whakakotahitanga me ētahi atu tāpiringa pēnei i te cellulose ether, te defoamer me te filler kia whiwhi ai i te hua hanga me te whakamahinga pai rawa atu.
Hei wāhanga nui kua whakarerekētia o ngā otinga whakakī kōhatu,Ka taea e te RDP te whakapai ake i te piri, te ngāwari, te ātete wai me te ātete huarere o ngā rauemi grouting., ā, ka tino whakapai ake i te mahi hanga me te kounga o ngā hua kua oti. Mā tōna whakamahinga i roto i te kōhatu maori, te māpere me te karāneti ka taea te whakaroa i te roa o te kaupapa me te pupuri i te ataahua o te whakaotinga kōhatu. I te heke mai, me te whanaketanga o te RDP mahi-teitei me te hoa-taiao, ka whakapai ake anō ngā otinga whakakī kōhatu ki te kaha teitei, te iti o te whakaheke me te roa o te mau.
