Ka taea te whakarāpopoto i te kaupapa o te rehu konutea wera penei: tuatahi, ka whakamahia te hau me ngā paipa pēhanga teitei hei pupuhi i ngā matūriki onepu ki runga i te mata o te mea mahi hei tango i te waikura me te unahi waikura i runga i te mata whakarewa, i te wā e whakangā ana te mata hei whakanui ake i te kaha mimiti o te paninga rehu wera. Kātahi ka whakamahia te hāora, te acetylene, te pūtake wera hiko rānei (ka whakamahia te whakamahana hiko mō ngā mea mahi nui, ka whakamahia te whakamahana hāora me te acetylene mō ngā mea mahi iti me te rahi waenga) mā te hau kōpeke me ngā taputapu motuhake (ngā pū rehu) hei rehu i te konutea i whakarewaina i te tere tino tere ki runga i te mata whakarewa.
Ngā Painga Whakarewa
1. Mā te whakapūkara makariri ka whakamahia te whakapūkara me te whakapūkara hei maimoatanga o mua, ka waiho he toenga waikawa me te kawakore ki te mata o te mea mahi, ka hanga he tūponotanga waikura, ā, ka ngāwari te tango i te paninga konutea tuku-matao. Mā te tukanga rehu konutea ka whakamahia te pupuhi onepu hei maimoatanga o mua, ka hua ake he mata tino ma, he taratara hoki. Mā tēnei ka ārai i te waikura mai i roto ki waho, me te tango konutea i muri i te rehu konutea.
2. Ko te whakapūmau wera-tuku me whai pāmahana motuhake o te 440°C, ka taea ai te whakarerekē i te āhua o te mea mahi. Heoi, he tino iti te pāmahana e whakamahia ana e te tukanga rehu konutea, i raro i te 80°C, hei ārai i te whakarerekētanga. 3. Ko ngā tukanga whakapūmau makariri me te tuku wera-tuku ka whakawhāiti i ngā mea mahi ki te roa, te whānui, me te teitei o te tāke whakapūmau, engari kāore ngā tukanga rehu konutea.
4. He uaua hoki te whakatika i te wāhi mahi i ngā tukanga whakapūkara makariri me te tuku wera. Ko ngā pakaru o ngā whakarewa i te wā e tāuta ana, e utaina ana, e tangohia ana rānei, e kawe ana rānei, ka taea anake te whakatika mā te peita. Mā te rehu konutea, ka taea te mahi whakatika i te wāhi mahi mā te rehu konutea, kia kore ai e araia te tukanga.
5. Nā te mea ka whakamahia te whakapūkara me te whakapūkara hei maimoatanga o mua i te whakapūkara makariri, he taratara te mata o te mea mahi, ā, he ngoikore te piri o te paninga. He rerekē, ka whakamahia te pupuhi onepu hei maimoatanga o mua i te rehu konutea, ka hua ake he taratara me te piri pai ake o te paninga, me te kaha kume o te ≥6 MPa.
6. He tino poke te wai i te whakapūkara makariri, ā, he nui ngā āwangawanga mō te taiao, engari he iti noa te pānga ki te taiao o te whakapūkara wera. Nō reira, ka piki haere te rongonui o te whakapūkara wera hei tiaki i te waikura o ngā hanganga maitai.
Tukanga Konutea rehu-wera
Ko te tukanga hanga katoa o te konutea ārai-waikura wera-rehu ka wehea kia whā ngā taahiraa: te maimoatanga mata → te rehu konutea → te maimoatanga hiri → te tirotiro kounga
Te Maimoatanga Mata
Nā te mea he pānga tika te kounga o te maimoatanga mata ki te kounga me te roa o te paninga, he mea nui te maimoatanga tika o te mata o raro. Whakangāwarihia te mata o raro ki te onepū hei tango i te waikura kia rite ki ngā whakaritenga o te tukanga. E piri ana ngā paerewa tango waikura ki te paerewa Sa3 i roto i te "Ngā Tohu Waikura me ngā Tohu Tango Waikura mō ngā Mata Rino i mua i te Peita" (GB8923-88). E whakamārama ana tēnei paerewa i ngā whakaritenga kounga e whai ake nei: Whakangāwarihia kia tino onepū hei tango i te unahi, te hinu, te waikura, te paru, te peita, me ētahi atu tāpiringa. Me whakaatu te mata i te kanapa whakarewa ōrite. Whai muri i te whakangāwari, horoia te mata ki te hau pēhi ma, maroke, ki te paraihe ma rānei. Me whai whakaaro hoki ki te paerewa Sa3 i roto i te "Ngā Tohu Waikura me ngā Tohu Tango Waikura mō ngā Mata Rino i mua i te Peita" (GB8923-88).
Te pupuhi onepu
I te wā e whakamahia ana, ka whakamahia ngā taputapu me ngā mehua e whai ake nei: he pūwero hau, he tāke hau, he wehewehe hinu-wai, he tātari hau, he ipu pupuhi onepu, he rīpene piri, he pū pupuhi onepu, me te pūwero porcelain ātete-kakahu. Ko te mea whakakoi he onepu awa koki-teitei te pakeke (0.5-2mm). Me maroke te onepu, me te ihirangi makuku iti iho i te 1%, ā, me ma, me te kore poke. Ka whakamahia e te pūwero he pūwero porcelain āhua-L e whakawhānui ana. I roto i te wāhanga whakawhānui-pēhanga-whakawhānui, ka eke te rere o te hau i waho o te pūwero onepu ki ngā tere supersonic, ka whakanui ake i te kaha nekeneke o te mea whakakoi, ka whakahohe ake me te hiko i te mata o te papa, ā, ka whakanui ake i te kaha piri o te paninga. Ko te tukanga tango waikura ko te hau pēhanga e tomo ana ki te tāke hau, ka haere mā te wehewehe hinu-wai me te tātari hau kia ma, kia maroke, kia kore he hinu, i mua i te urunga ki te ipu pupuhi onepu. Ka pēhia e te rīpene piri te onepu ki roto i te pū pupuhi onepu ka pupuhihia ki runga i te papa whakarewa. Mā te whakamahi i ēnei taputapu me ngā āhuatanga, ka taea e te maimoatanga mata te tutuki i ngā paerewa Sa3, me te taratara o te mata o te 40-60µm. I tēnei wā, kua eke te pūmanawa hiko, te taumata whakahohenga, me te piri o te paninga o te mata whakarewa ki ngā tawhā tino pai.
Te Rehu Konutea
Me whakaoti te rehu konutea i roto i ngā hāora e 2-3 o te pupuhi onepu. Nā te mea he rerekē rawa te pūmanawa hiko o te mata o te papa i muri i te pupuhi onepu i tērā i mua i te maimoatanga, ka eke ki tōna pūmanawa iti rawa. I tēnei wā, ka eke te whakahohenga o te mata o te papa ki tōna uara teitei rawa, ā, ko te kaha here i waenga i te papa me te paninga kei tōna taumata teitei rawa. Ka noho pumau tonu te pūmanawa hiko i runga i te mata o te papa mō ngā hāora e 2-3. I roto i te wā, ka tīmata te pikinga o te pūmanawa hiko o te mata, ka ngoikore te kaha whakahohenga, ā, ka heke te kaha here i waenga i te paninga me te papa. Nā te matotoru o te kiriata waikura mata tēnei. I roto i ngā hāora e 2-3, ka ngawari te pakaru o te kiriata waikura angiangi e ngā matūriki rehu tere-rahi ina pā ki te mata. I muri i ngā hāora e 2-3, ka mahi te kiriata waikura hei ārai i waenga i te paninga me te papa, ka whakararu i te piri i waenga i te paninga me te papa. Ka whakamahia e ngā taputapu rehu he pū rehu i hangaia i te motu (he pū rehu ringaringa hau Zhonglian mai i te Shanghai Spraying Machinery Factory). Ko te rauemi konutea i whakamahia he waea konutea kounga teitei, kāore he hinu, he 3 mm te whānui, ā, ko te nui o te konutea he 99.5%-99.7% te iti rawa.
