Ngā take e puta ai ngā mirumiru i te wā e whakaoho ana:
Te take e puta ai ngā mirumiru i te wā e whakaranua anakapia epoxyKo te take o te kāpia, ko te hau e whakaurua ana i te wā e whakaoho ana ka puta he mirumiru. Ko tētahi atu take ko te "pānga cavitation" i puta mai i te tere rawa o te whakaoho i te wai. E rua ngā momo mirumiru: e kitea ana, e kore e kitea. Mā te whakamahi i te tango hau korehau ka taea anake te whakakore i ngā mirumiru e kitea ana, engari kāore e whai hua ki te tango i ngā mirumiru iti e kore e kitea e te kanohi tangata.
Ngā take e puta ai ngā mirumiru i te wā e whakamaroke ana:
Nā te mea ka whakamaroketia te kapia epoxy mā te polymerization, he tauhohenga matū tēnei. I te wā o te tauhohenga whakamaroketia, ka wera, ka whānui hoki ngā mirumiru iti i roto i te pūnaha kapia epoxy, ā, kāore te hau e hototahi ki te pūnaha epoxy, kātahi ka huihui hei hanga mirumiru nui ake.
Ngā take o te pahuka o te kapia epoxy:
(1) Ngā āhuatanga matū kore pumau
(2) Te whakaranu i te wā e whakarite ana i te whakamātotoru
(3) Te huka i muri i te kohikohinga o te whakamātotoru
(4) Te tukanga tukunga paru
Ngā tūponotanga o te pahuka o te kapia epoxy i te wā e whakaranu ana:
(1) Ka puta te puhake me te whakapaunga matotoru i te pahuka, ka pā hoki tēnei ki te teitei o te taumata wai e kitea ana.
(2) Ka pāngia te whai huatanga o te hanga e ngā mirumiru i puta mai i ngā amine ngota o te matū whakaora.
(3) Mā te noho mai o ngā "mirumiru mākū" ka puta te whakapūhui hau VCM, e puta whānuitia ana i roto i te ipu piri.
(4) Ki te kore e tangohia katoatia ngā mirumiru i te wā e hangaia ana, ka puta ake ngā mirumiru i muri i te whakamaroke, ā, ka maha ngā kōhao iti i runga i te mata i muri i te whakamaroke, ka pā kino ki te kounga o te hua.
Me pēhea te tango i ngā mirumiru hau?
Ngā momo hua o te rongoā whakakore huka e whakamahia whānuitia ana: ngā rongoā whakakore huka silicone, ngā rongoā whakakore huka kore-silicon, ngā rongoā whakakore huka polyether, ngā rongoā whakakore huka hinu kohuke, ngā rongoā whakakore huka waipiro waro-nui, me ētahi atu.
Ina iti te pāmahana, ka puta ngā panoni ki ngā āhuatanga o te nuinga o ngā matū wai, inā koa ka piki ake te matotoru o ngā matū wai piri i te hekenga o te pāmahana.Kāpia kapia epoxy ab, hei matū wai noa, he nui te pikinga o te uara matotoru nā te hekenga o te pāmahana. Nō reira, i te wā e whakamahia ana, e whakamahia ana, he uaua ki te whakakore i ngā mirumiru, ka heke te mahi whakatārewatanga, ā, ko te pikinga o te wā whakamahi me te wā whakamaroke kāore e pai mō te whakaputa me te whakahaere noa. Heoi, nā te kohikohinga o ngā tau maha o te wheako whakaputa, kua whakarapopototia e mātou ētahi wheako āwhina hei whakaoti pai me te whakaiti i ngā raruraru i puta mai i ngā raruraru o runga ake nei. Ina koa, e whā ngā tikanga e whai ake nei:
1. Tikanga whakamahana papa mahi:
Ina heke te pāmahana i te papa mahi ki te 25°C, me whakamahana te papa mahi kia eke te pāmahana ki te pāmahana e tika ana mō te mahi whakapiripiri (25°C~30°C). I taua wā anō, me pupuri te haumākū o te hau i te papa mahi ki te 70% pea, kia rite rā anō te pāmahana o te whakapiripiri ki te pāmahana taiao i mua i te mahi tika o te whakapiripiri.
He whakamaumahara mahana: Ko tēnei tikanga te tikanga tino whai hua, engari he nui te utu whakahaere, tēnā kia aro ki te kaute utu.
2. Tikanga whakamahana wai kohua:
Ka whakaiti tika te whakamatao i te uara matotoru okapia epoxykāpia ab, ā, ka nui ake te whakanui. Mā te whakamahana i mua i te whakamahinga o te kāpia ka piki ake tōna ake pāmahana, ka whakaiti i te uara matotoru, ka māmā ake te whakamahi. Ko te tikanga motuhake ko te tāpiri i te oko katoa, te pounamu rānei o te kāpia ki roto i te wai kohua, ka whakamahana mō te 2 hāora i mua i te whakamahinga o te kāpia, kia eke te pāmahana o te kāpia ki te 30℃, kātahi ka tangohia, ka rūrūtia kia rua, kātahi ka pupuri i te kāpia A ki te pāmahana kaua e iti iho i te 30℃ i roto i te wai mahana, ā, whakamahia i te wā e whakamahana ana. I te wā e whakamahia ana, tangohia te kāpia ka rūrūtia ia hawhe hāora kia ōrite te pāmahana me te hanganga o te kāpia. Engari kia tino tupato kei piri te kāpia i roto i te peere, i te pounamu rānei ki te wai, ki te kore ka puta he hua kino, he hua kino rānei.
He whakamaumahara mahana: He māmā noa iho tēnei tikanga, he iti te utu, ā, he whai hua hoki, ā, he tino māmā te utu me ngā rauemi. Heoi anō, kei reira ētahi tūponotanga huna me aro atu ki tēnā.
3. Tikanga whakamahana oumu:
Ka taea e ngā kaiwhakamahi kei a rātou ēnei āhuatanga te whakamahi i te kapia epoxy ab hei whakamahana i te kāpia i roto i te oumu i mua i te whakamahinga o te kāpia kia kore ai e pā kino ki te wai. He tino māmā noa iho. Ko te tikanga motuhake ko te whakarite i te pāmahana o te oumu ki te 60°C, kātahi ka maka te oko katoa, te pounamu rānei o te kāpia A ki roto i te oumu hei whakamahana, kia eke te pāmahana o te kāpia ki te 30°C, kātahi ka tangohia te kāpia ka rūrū kia rua ngā wā, kātahi ka whakanoho i te kāpia ki te pāmahana o te 30°C i waenganui o te oumu mā te whakamahi i ngā taha kua whakamahanahia, engari kia tupato ki te tango i te kāpia ka rūrū mō te haora pea kia mau tonu te pāmahana ōrite o te kāpia ki ngā kai.
He whakamaumahara mahana: Ka paku piki ake te utu e tēnei tikanga, engari he tino māmā, he whai hua hoki.
4. Tikanga āwhina mō te whakakore huka:
Hei tere ake i te tango i ngā mirumiru, ka taea hoki e koe te hoko i tētahi kaihoko whakakore huka motuhake mō te kāpia epoxy kua tāpirihia ki te kapia, ka tāpirihia he kāpia A me te ōwehenga o te 3‰ ki roto, mā te tikanga motuhake; tāpirihia tika kia kaua e neke atu i te 3% o te kāpia ki te kāpia A kua werahia mā te tikanga o runga ake nei. He kaihoko whakakore huka motuhake mōkāpia AB kapia epoxy, kātahi ka whakaohokia kia ōrite, ka whakaranua ki te kāpia B hei whakamahi.
