Te Tūranga o te Konupūmā Formate i roto i te Konukuraiti
Te Tūranga o te Konupūmā Formate i roto i te Konukuraiti E rua ngā mahi matua a te konupūmā formate i roto i te konukuraiti: Te Whakaiti Wai: Ka mahi te konupūmā formate hei whakaiti wai i roto i te konukuraiti. Ka whakaitihia e ia te ōwehenga wai-sima o te konukuraiti, ka whakapai ake i tōna rere me te kaha papu. Mā te whakaiti i te nui o te wai e tāpirihia ana, ka whakarei ake...Pānuihia atu -
He aha te tukanga whakaputa matomato o te konupūmā formate?
He Tukanga Whakaputa Kakariki Mā te Whakamahi i te CO me te Ca(OH)₂ hei Rauemi Mata o te konupūmā formate Ko te tukanga whakaputa mā te whakamahi i te waro haukini (CO) me te konupūmā hauwai (Ca(OH)₂) hei rauemi mata he painga pēnei i te whakahaere ngāwari, te kore o ngā hua taha kino, me te whānuitanga o ngā pūtake rauemi mata. He mea nui, ka tutuki...Pānuihia atu -
He aha ngā tikanga matua mō te hanga konupūmā formate?
I tēnei wā, e rua ngā wāhanga o ngā tikanga hanga matua mō te konupūmā formate i Haina: te hanga hua tuatahi me te hanga hua taha. Ko te tikanga hanga hua taha—i ahu mai i te hanga polyol—kua āta whakamutua haeretia nā ngā take pēnei i te whakamahinga o te hau chlorine, te hua taha...Pānuihia atu -
He aha te whakamahinga o te konupūmā formate?
Ko te konupūmā formate, e mōhiotia ana ko te Calcium Diformate, e whakamahia whānuitia ana ehara i te mea hei tāpiri whāngai me te kaihoko tango whanariki mō te hau paru mai i te tahunga wahie whanariki-nui anake, engari hei takawaenga hoki i roto i te hanga patu taru, hei kaiwhakahaere tipu tipu, hei āwhina i roto i te umanga hiako, me te tautoko...Pānuihia atu -
He pēhea te mahi a te konupūmā formate i roto i te sima?
Te whakapai ake i te mahi a te sima: Mā te horopeta tika o te konupūmā formate ka whakarei ake i te ngāwari me te ngāwari o te sima, ka whakapai ake i tōna ngāwari ki te tukatuka me te hanga. Mā tēnei ka māmā ake te whakaranu, te riringi, me te whakakīkī i te ranunga sima. Te whakanui ake i te kaha o te sima: Ka whakatairanga te konupūmā formate i te...Pānuihia atu -
He aha te mahi a te konupūmā formate i roto i te sima?
Te Tūranga o te Konupūmā Formate i roto i te Sima He maha ngā mahi matua a te konupūmā formate i roto i te sima: Te whakaroa i te taunga me te whakapakeketanga o te sima: Ka tauhohe te konupūmā formate ki te wai, ka tauhohe hoki te konupūmā sulfate whakamakuku i roto i te sima hei whakaputa i te konupūmā diformate me te konupūmā sulfate. Ka whakaitihia e tēnei tauhohenga te tere o te whakamakuku...Pānuihia atu -
Ka taea te whakamahi i te konupūmā formate hei ātete ki te tauraki?
Ko te tikanga, ko te pāmahana hanga kiriata o te paura rapa ka taea te whakamarara anō kei runga ake i te 0°C, ko ngā hua EVA ia he pāmahana hanga kiriata kei te 0–5°C. I ngā pāmahana iti iho, kāore e taea te hanga kiriata (he ngoikore rānei te kounga o te kiriata), ka whakararu i te ngāwari me te piri o te polymer mo...Pānuihia atu -
He aha te mahi a te konupūmā formate i roto i te sima?
I ngā pāmahana iti, ka puhoi te tere o te makuku, ka pā ki te whai huatanga o te hanga. Ina heke te pāmahana ki raro i te hukapapa, ka huri te wai hei hukapapa, ka whānui te rahinga, ā, ka ngāwari ki te puta he hapa pēnei i te poka me te tihore. I muri i te mimiti o te wai, ka nui haere ngā āputa o roto, he mea nui...Pānuihia atu
