Me pēhea te whiriwhiri i te mowhiti hiri mō te pūnaha waipēhi?
1, 1. Rauemi: Koinei te hiri rapa e whakamahia whānuitia ana, ā, he iti rawa te utu. Kāore e pai mō te whakamahi i roto i ngā whakarewa pōro pērā i te ketone, te ozone, ngā nitrohydrocarbons, te MEK me te chloroform. Kāore e pai mō te whakamahi i roto i ngā whakarewa pōro pērā i te ketone, te ozone, ngā nitrohydrocarbons, te MEK me te chloroform. Ko te awhe pāmahana whānui ko -40~120 ℃. Tuarua, he pai te ātete waikura o te mowhiti hiri rapa nitrile hauwaiwai HNBR, te ātete haehae me ngā āhuatanga whakarerekētanga pēhanga, te ātete ozone, te ātete ki te rā, te ātete huarere. He pai ake te ātete kakahu i te rapa nitrile. He pai mō ngā mīhini horoi, ngā pūnaha miihini motuka me ngā pūnaha pouaka whakamātao e whakamahi ana i te hauhautanga taiao hou R134a. Kāore i te tūtohutia kia whakamahia i roto i ngā waipiro, ngā esters, ngā otinga kakara rānei. Ko te awhe pāmahana whānui ko -40~150 ℃. Tuatoru, he pai ngā painga o te mowhiti hiri rapa silicone fluorine FLS ki te rapa fluorine me te rapa silicone, te ātete hinu, te ātete whakarewa, te ātete hinu wahie me te ātete pāmahana teitei me te iti. He ātete ki te whakaekenga a ngā matū kei roto te hāora, ngā whakarewa kei roto te hauwai kakara me ngā whakarewa kei roto te hauwaiwai. E whakamahia whānuitia ana mō ngā mahi rererangi, te rererangi me te ope taua. Kāore i te tūtohutia kia pāngia e ngā ketone me ngā wai parai. Ko te awhe pāmahana whānui ko -50~200 ℃.
2, mahi: Haunga ngā whakaritenga whānui o te rauemi mowhiti hiri, me aro hoki te mowhiti hiri ki ngā āhuatanga e whai ake nei: (1) he pīngore me te ātete; (2) he kaha ā-pūkaha e tika ana, tae atu ki te kaha whakawhānui, te roa me te kaha haehae. (3) he pumau te mahi, kāore e ngāwari te pupuhi i roto i te reo, ā, he iti te pānga whakaheke wera (te pānga Joule). (4) he ngāwari ki te tukatuka me te hanga, ā, ka taea te pupuri i te rahi tika. (5) kāore e waikura te mata pa, kāore e poke i te reo, me ētahi atu. Ko te rauemi tino pai me te nuinga o te wā e whakamahia ana hei whakatutuki i ngā whakaritenga o runga ake nei ko te rapa, nō reira ko te nuinga o te mowhiti hiri he mea hanga ki te rauemi rapa. He maha ngā momo rapa, ā, kei te puta tonu ngā momo rapa hou, me te hoahoa me te whiriwhiri, me mārama ki ngā āhuatanga o ngā momo rapa, me te whiriwhiri tika.
3, ngā painga: 1, me pai te mahi hiri o te mowhiti hiri i roto i te pēhanga mahi me te awhe pāmahana kua whakaritea, ā, mā te pikinga o te pēhanga ka taea te whakapai ake i te mahi hiri. 2. Me iti te waku i waenga i te taputapu mowhiti hiri me ngā wāhanga neke, ā, me pumau te tauwehenga waku. 3. He kaha te ātete waikura o te mowhiti hiri, kāore e ngāwari ki te tawhito, he roa te ora mahi, he pai te ātete kakahu, ā, ka taea te utu aunoa i muri i te kakahu ki tētahi taumata. 4. He hanganga māmā, he ngāwari ki te whakamahi me te tiaki, kia roa ake ai te ora o te mowhiti hiri. Ka puta he turuturu i te pakaru o te mowhiti hiri, ka hua ake he moumou o ngā rauemi mahi, he poke o te mīhini me te taiao, ā, ka puta he rahunga mahi miihini me ngā aituā whaiaro o ngā taputapu. Ka puta he turuturu ā-roto i te hekenga tere o te pai o te pūnaha waipēhi, ā, kāore e taea te whakatutuki i te pēhanga mahi e hiahiatia ana, kāore rānei e taea te mahi. Ka taea e ngā matūriki puehu iti e uru ana ki te pūnaha te whakararu, te whakanui ake rānei i te kakahu o ngā takirua waku o ngā wāhanga waipēhi, ka arahi atu ki ngā turuturu. Nō reira, he wāhanga nui o ngā taputapu waipēhi ngā hiri me ngā taputapu hiri. Ko te pono me te roa o te mahi he tohu nui hei ine i te kounga o te pūnaha waipēhi.
