Ko te porosity i roto i te whakarewa laser he hapa nui e tautuhia ana ko ngā āputa hau e mau ana i roto i te konganuku whakarewa totoka. Ka whakararu tika i te kounga miihini, te kaha whakarewa, me te roa o te ngenge. Ka whakaratohia e tēnei aratohu he huarahi tika, he otinga-tuatahi, e whakauru ana i ngā kitenga mai i ngā rangahau hou i roto i te hanga hihi matatau me te whakahaere tukanga e whakahaerehia ana e te AI hei whakaatu i ngā rautaki whakaiti tino whai hua.
Te Tātaritanga o te Porosity: Ngā Take me ngā Pānga
Ehara te pūngao i te hapa kotahi-tikanga; e puta mai ana i ētahi āhuatanga ā-tinana me ā-matū rerekē i te wā o te tukanga whakarewa tere. He mea nui te mārama ki ēnei pūtake hei ārai whai hua.
Ngā Take Matua
Parahanga o te Mata:Koinei te pūtake tino maha o te pūngao whakarewa. He nui te hauwai i roto i ngā poke pēnei i te makuku, ngā hinu, me ngā hinu whakangao. I raro i te kaha kaha o te taiaho, ka pirau ēnei matū, ka werohia te hauwai taketake ki roto i te konganuku rewa. I te whakamatao me te totoka tere o te puna whakarewa, ka heke te wairewa o te hauwai, ka panaia kia puta i te wairewa kia puta ai ngā pūngao porowhita angiangi.
Te Pūmautanga o te Kōhao Kī:Koinei te pūtake matua o te pūngao o te tukanga. He mea nui te pū kōhao kī pumau mō te whakarewatanga pai. Ki te kore e arotauhia ngā tawhā tukanga (hei tauira, he tere rawa te whakarewatanga mō te mana o te taiaho), ka taea e te pū kōhao kī te huri, te kore pumau, me te hinga mō te wā poto. Ka mau i ia hinganga he pute o te kohu whakarewa pēhanga teitei me te hau tiaki i roto i te puna rewa, ka hua ake he āputa nui, he āhua koretake.
Te Parenga Hau Kāore i te Rawaka:Ko te kaupapa o te ārai hau he neke i te āhuarangi e karapoti ana. Mēnā kāore e ranea te rere, mēnā rānei ka nui rawa te rere ka puta he pōrearea e kukume ana i te hau, ka poke te whakarewa i ngā hau o te āhuarangi—ko te hauota me te hāora te nuinga. Ka tere te hanga waikura totoka a te hāora i roto i te whakarewa, engari ka taea te mau te hauota hei pūwero, te hanga rānei i ngā matū nitride pakarukaru, ā, ka whakararu i te āhua o te whakarewa.
Ngā Pānga Kino
Ngā Āhuatanga Mīhini Kua Whakaitihia:Ka whakaitihia e ngā pūwero te horahanga whakawhiti-wāhanga o te whakarewa, ka whakaheke tika i tōna Kaha Kukume Tino. He mea nui ake, ka mahi rātou hei āputa ā-roto e ārai ana i te whakarerekētanga kirihou ōrite o te konganuku i raro i te kawenga. Ko te ngaronga o te haere tonu o ngā rauemi ka tino whakaiti i te ngāwari, ka pakarukaru ake te whakarewa, ka ngawari hoki te pakaru ohorere.
Te Oranga o te Ngenge Whakararuraru:Koinei te hua tino kino i te nuinga o te wā. Ko ngā pūwero, inā koa ko ngā mea he koi ngā kokonga, he kaha ki te whakaemi i te ahotea. Ina pāngia tētahi wāhanga e te utaina huringa, ka taea e te ahotea i te taha o te pūwero te nui ake i te ahotea whānui i roto i te wāhanga. Mā tēnei ahotea nui ā-rohe ka tīmata ngā kapiti moroiti e tipu ana i ia huringa, ka arahi ki te rahunga ngenge i raro iho i te kaha pumau kua whakatauria o te rauemi.
Te Whakaraeraetanga Nui Ake ki te Waikura:Ina pakaru te mata i te pūwero, ka hangaia he wāhi mō te waikura o te kapiti. He rerekē te hanganga matū o te taiao iti, pūmau i roto i te pūwero i tō te mata e karapoti ana. Nā tēnei rerekētanga ka hangaia he pūtau hikohiko e tere haere ana i te waikura ā-rohe.
Te Waihanga o ngā Ara Tūtaki:Mō ngā wāhanga e hiahia ana ki te hiri ā-hiri—pērā i ngā taupoki pākahiko, i ngā rūma korehau rānei—he āhuatanga pakaru tonu te pūngao. Mā te pūngao kotahi e toro atu ana i te mata o roto ki waho ka puta he ara tika mō ngā wai, ngā hau rānei kia turuturu, ka kore ai e whai hua te wāhanga.
Ngā Rautaki Whakaiti Mahi hei Whakakore i te Porosity
1. Ngā Mana Whakahaere Tukanga Tūāpapa
Te Whakarite Mata Atawhai
Koinei te tino take o te porosity. Me horoi pai ngā mata katoa me ngā rauemi whakakī i mua tonu i te whakarewanga.
Te Horoi Whakarewa:Whakamahia he whakarewa pēnei i te acetone, te waipiro isopropyl rānei hei horoi pai i ngā mata whakarewa katoa. He taahiraa nui tēnei nā te mea ka pirau ngā poke hauwai (hinu, hinu, wai tapahi) i raro i te wera nui o te laser, ka werohia te hauwai tika ki roto i te puna whakarewa rewa. I te tere o te whakapakeketanga o te konganuku, ka hangaia e tēnei hau kua mau he porosity pai e whakaiti ana i te kaha o te whakarewa. Ka mahi te whakarewa mā te whakarewa mā te whakarewa i ēnei matū, ka taea te muru katoa i mua i te whakarewa.
Kia tūpato:Āta karohia ngā whakarewa he hauwai, nā te mea ka pirau pea ōna toenga hei hau kino, ā, ka pakarukaru.
Te Horoi Ā-Mīhini:Whakamahia he paraihe waea kowiri tira motuhake mō ngā kowiri tira, he paraihe karāhe rānei hei tango i ngā waikura matotoru.whakatapuaHe mea nui te paraihe hei ārai i te whakawhiti poke; hei tauira, mā te whakamahi i te paraihe maitai waro ki runga i te maitai kore waikura ka uru pea ngā matūriki rino ka waikura i muri mai, ka whakararu i te whakarewa. He mea nui te pūwero karāhe mō ngā waikura matotoru, pakari hoki nā te mea he kaha ki te tapahi ā-tinana i te paparanga me te whakaatu i te konganuku hou, ma i raro.
Te Hoahoa Hononga Tika me te Whakapiri
Ko ngā hononga kāore i te pai te taunga me ngā āputa nui he tino take o te porosity. Kāore e taea e te hau tiaki e rere ana mai i te pūwero te neke pono i te hau e mau ana i roto i te āputa, ka taea ai te kume ki roto i te puna whakarewa.
Aratohu:Kaua ngā āputa hononga e neke ake i te 10% o te matotoru o te rauemi. Ki te nui rawa atu tēnei, ka kore e pumau te puna whakarewa, ā, ka uaua ki te tiaki e te hau tiaki, ka piki ake te tūponotanga o te mau o te hau. He mea nui te whakapiri tika kia mau tonu ai tēnei āhua.
Arotautanga Tawhā Pūnaha
Mā te hononga i waenga i te mana o te taiaho, te tere whakarewa, me te tūnga arotahi ka hangaia he matapihi tukanga. Me whakamana tēnei matapihi kia tino puta he kōhao kī pumau. Ka taea e te kōhao kī pumau te hinga i ētahi wā i te wā whakarewa, ka mau ai ngā mirumiru o te konganuku mimiti me te hau tiaki.
