Te whakarewa parahi
Ko ngā tikanga whakarewa parahi (e kiia whānuitia ana ko te parahi parakore ā-umanga) ko te whakarewa hau, te whakarewa pewa waro ā-ringa, te whakarewa pewa ā-ringa me te whakarewa pewa hauhā ā-ringa, ā, ka taea hoki te whakarewa aunoa i ngā hanganga nunui.
1. Ko te hononga whakarewa hau parahi e whakamahia whānuitia ana ko te hononga papatahi, ā, me whakamahi iti noa te hononga taupoki me te hononga T. E rua ngā momo waea whakarewa ka taea te whakamahi mō te whakarewa hau. Ko tētahi he waea whakarewa kei roto ngā huānga tango-hāora, pērā i ngā waea 201 me te 202; ko tētahi he waea parahi whānui me te rīpene tapahi o te rauemi turanga, ā, ko te kaihopu hau 301 ka whakamahia hei rere. Me whakamahi te mura kūpapa i te wā e whakarewa ana i te parahi.
2. Ka whakamahia te tokotoko waea parahi parahi 107 mō te whakarewa ā-ringa, ā, ko te matua whakarewa he parahi (T2, T3). Me horoi ngā taha o te whakarewa i mua i te whakarewa. Mēnā he nui ake te matotoru o te whakarewa i te 4 mm, me whakamahana mua i mua i te whakarewa, ā, ko te pāmahana whakamahana i te nuinga o te wā he 400~500℃. Mēnā he whakarewa ki te tokotoko whakarewa parahi 107, me huri te pūtake hiko mā te DC.
3. Me whakamahi ngā pewa poto i te wā e whakarewa ana, ā, kaua te tokotoko whakarewa e piu whakapae. Ka mahi te tokotoko whakarewa i tētahi nekehanga rārangi, ka taea te whakapai ake i te hanganga o te whakarewa. Me whakarewa mārire te whakarewa roa. Me tere te tere o te whakarewa. I te wā e whakarewa ana i ngā paparanga maha, me tango katoa te paru i waenganui i ngā paparanga. Me mahi te whakarewa i roto i tētahi wāhi hauhautanga pai hei ārai i te paitini parahi. I muri i te whakarewa, whakamahia he hama pane-papatahi hei patuki i te whakarewa hei whakakore i te ahotea me te whakapai ake i te kounga o te whakarewa.
4. Te whakarewa ā-ringa i te parahi me te pewa argon. Mēnā ka whakarewa ā-ringa i te parahi me te pewa argon, ko ngā waea e whakamahia ana ko te waea 201 (waea whakarewa parahi motuhake) me te waea 202, ā, ka whakamahia hoki he waea parahi, pērā i te T2.
I mua i te whakarewanga, me horoi te kiriata waikura, te hinu me ētahi atu paru i ngā taha whakarewa o te mea mahi me te mata o te waea kia kore ai e puta he hapa pēnei i ngā pūwero me ngā para. Ko ngā tikanga horoi ko te horoi miihini me te horoi matū. Mēnā he iti iho i te 3 mm te matotoru o te pereti hononga matua, kāore e whakatuwheratia te kōhao; mēnā he 3 ki te 10 mm te matotoru o te pereti, ka whakatuwheratia te kōhao āhua-V, ā, ko te koki kōhao he 60 ki te 70; mēnā he nui ake i te 10 mm te matotoru o te pereti, ka whakatuwheratia te kōhao āhua-X, ko te koki kōhao he 60~70; kia kore ai e whakarewahia, ka waihohia ngā taha pūngoi. E ai ki te matotoru o te pereti me te rahi o te kōhao, ka tīpakohia te āputa huihuinga o te hononga matua i roto i te awhe o te 0.5 ki te 1.5 mm.
Ko te tikanga, ko te hononga DC pai te whakamahi i te hononga ā-ringa o te whakarewa parahi argon, arā, ka honoa te hiko tungsten ki te hiko kino. Hei whakakore i ngā kōhao hau, hei whakarite hoki i te hononga pono me te urunga o ngā pakiaka whakarewa, me whakanui ake te tere whakarewa, me whakaiti te whakamahinga argon, me te whakamahana i te whakarewa. Mēnā he iti iho i te 3 mm te matotoru o te pereti, ko te pāmahana whakamahana tuatahi he 150~300℃; mēnā he nui ake i te 3 mm te matotoru o te pereti, ko te pāmahana whakamahana tuatahi he 350~500℃. Kaua e tino teitei te pāmahana whakamahana tuatahi, ki te kore ka whakaitihia ngā āhuatanga ā-pūkaha o ngā hononga whakarewa.
Kei reira anō te whakarewanga pewa parahi waro, ā, ko ngā irahiko e whakamahia ana mō te whakarewanga pewa waro ko ngā irahiko waro me ngā irahiko karāpeti. Ko te waea whakarewanga e whakamahia ana mō te whakarewanga pewa parahi waro he rite tonu ki te whakarewanga hau. Ka taea hoki te whakamahi i te rauemi turanga hei tapahi i ngā rīpene, ā, ka taea te whakamahi i ngā rerenga parahi pēnei i te kaihopu hau 301.
Te whakarewa parahi
1. Ko ngā tikanga mō te whakarewa parahi ko: te whakarewa hau, te whakarewa pewa waro, te whakarewa pewa ā-ringa me te whakarewa pewa haukoni. 1. Te whakarewa hau o te parahi Nā te mea he iti te pāmahana o te mura whakarewa hau, he iti ake te mimiti o te konutea i roto i te parahi i te wā whakarewa i tērā i te wā e whakamahi ana i te whakarewa hiko, nō reira ko te whakarewa hau te tikanga e whakamahia whānuitia ana i roto i te whakarewa parahi (ngā mihi ki a koe mō te aro ki te Whakarewa Aunoa a Dingding).
Ko ngā waea whakarewa e whakamahia ana mō te whakarewa hau parahi ko: te waea 221, te waea 222 me te waea 224. Kei roto i ēnei waea whakarewa ngā huānga pēnei i te silicon, te tine, te rino, me ētahi atu, ka taea te ārai me te whakaiti i te mimiti me te tahunga o te konutea i roto i te puna rewa, ā, he pai hoki mō te whakarite i te whakarewa. Te mahi me te ārai i ngā kōhao hau. Ko ngā rerenga e whakamahia whānuitia ana i roto i te whakarewa hau parahi ko te paura totoka me te rerenga hau. Ko te rerenga hau he waikawa boric, te ngako methyl me te methanol; ko ngā rerenga he pēnei i te kaihoko hau 301.
2. Te whakarewa ā-ringa i te parahi Haunga te parahi 227 me te parahi 237, ka taea hoki te whakamahi i ngā tokotoko whakarewa i hangaia i te kāinga mō te whakarewa i te parahi.
I te wā e whakarewahia ana te pewa parahi, me whakamahi te tikanga hononga pai o te pūtake hiko DC, ā, me hono te tokotoko whakarewa ki te hiko kino. Me horoi marie te mata o te whakarewa i mua i te whakarewa. Ko te koki piko me kaua e iti iho i te 60~70o. Hei whakapai ake i te hanganga whakarewa, me whakamahana ngā wāhanga whakarewa ki te 150~250oC. Me whakamahi te whakarewa pewa poto i te wā e mahi ana, kaua e neke whakapae, kaua hoki e neke whakamua, kaua hoki e neke whakamuri, engari me neke noa i te raina, ā, me tere te whakarewa. Ko ngā wāhanga whakarewa parahi e pā ana ki ngā mea waikura pēnei i te wai moana me te haukini me whakamahana i muri i te whakarewa hei whakakore i te ahotea whakarewa.
3. Te whakarewa ā-ringa i te parahi me te pewa argon. Ka taea te whakamahi i ngā waea parahi paerewa mō te whakarewa ā-ringa i te parahi me te pewa argon: te waea 221, te waea 222 me te waea 224, ā, ka taea hoki te whakamahi i ngā rauemi he rite ngā wāhanga ki te rauemi turanga hei rauemi whakakī.
Ka taea te whakarewa mā te au tika, mā te AC rānei. Mēnā ka whakamahia te whakarewa AC, he māmā ake te mimiti o te konutea i te wā e honoa ana te au tika. I te nuinga o te wā, kāore e hiahiatia te whakamahana i mua i te whakarewa, ā, ka whakamahanahia anake ina he nui te matotoru o te pereti. Me tere te tere whakarewa. I muri i te whakarewa, me whakamahana ngā wāhanga whakarewa ki te 300~400℃ kia whakamahanahia hei whakakore i te ahotea whakarewa hei ārai i ngā pakaru o ngā wāhanga whakarewa i te wā e whakamahia ana.
4. Te whakarewa waro waro parahi Ina whiriwhiria te whakarewa waro waro parahi, te waea 221, te waea 222, te waea 224 me ētahi atu waea whakarewa kia rite ki te hanganga o te rauemi turanga. Ka taea hoki e koe te whakamahi i ngā waea whakarewa parahi i hangaia i te kāinga hei whakarewa. Ka taea te whakamahi i te hau 301, i ērā atu mea rānei hei rere i roto i te whakarewa. Me whakahaere te whakarewa i roto i te pewa poto hei whakaiti i te mimiti o te konutea me te kino o te wera.
