Ko te ngongo EP tētahi o ngā hua matua a te kamupene. Ko tana tukanga matua he whakakanapa hiko i te mata o roto o te ngongo i runga i ngā ngongo kanapa.
He katote tēnei, ā, ka rumakina ngā pou e rua ki roto i te pūtau hikohiko me te ngaohiko o te 2-25 volts i te wā kotahi. Mā te mahi a te iahiko ka puta he tauhohenga matū kaha me te whakarewanga anodic whiriwhiri. I te nuinga o te wā, ka whakarewahia tuatahitia te pūwāhi teitei o te mata whakarewa i te wā e whakakanapahia ana, kia tutuki ai te hua o te whakanui ake i te kanapa o te mata o te mea mahi.
Ko ngā āhuatanga matua o te whakakanapa hiko ko te pāmahana o te irahiko, te kaha o te katote (te tawhiti i waenga i te katote me te mea mahi hei whakakanapa), te kukū o te otinga waikawa, me te wā whakakanapa hiko. I raro i ngā āhuatanga noa, ka whakatauhia te roa o te wā e rumakina ai te matū kua whakakanapahia ki roto i te tāke whakakanapa hiko i runga i ngā āhuatanga o te mea mahi e makahia ana. i roto i te wā poto ka tangohia.
Ka taea e te whakakanapa hiko te whakanui ake i te ātete ki te waikura o te mata o ngā paipa kowiri tira, me te whakarite kia ōrite te tae o roto, o waho hoki; ka taea e te whakakanapa hiko te whakaatu i ngā hapa o te mata e kitea ana, ka taea ai te whakaiti i te horahanga o roto o te kowiri tira, te whakanui ake i te maeneene o te mata, me te whakahaere i te whakatutukitanga o ngā taputapu. He tere, he pai hoki te horoi me te tango whai hua i ngā kokiritanga o te mata i puta mai i te whakakanapa miihini ka puta ai te waikura me te tae ke o te rino.
Mā te whakakanapa hiko ka tangohia ngā katote rino kore utu i runga i te mata, ka āwhina tēnei ki te whakanui ake i te ōwehenga Cr/Fe i runga i te mata, te whakarei ake i te paparanga tiaki pāhekoheko, me te whakaiti i te tūponotanga o te waikura whero i roto i te pūnaha. He maeneene ake, he papatahi ake te whakakanapa hiko i te whakakanapa mīhini. Nō reira, e kī ana te "ASME BPE" kia kaua e iti iho i te 15Å te matotoru o te paparanga pāhekoheko o te whakakanapa hiko.
Ka whakamahia e Zhongrui te horoi matū ultrasonic hei whakatutuki i ngā whakaritenga o te ASTM G93, SEMI E49.6 rānei. I muri i te horoinga o te ngongo tino ma ki te wai tino parakore 18MΩ deionized, ka pupuhihia te ngongo kua parakore ki te hau hauota tino parakore o te 99.999%, ka whakakīia ki roto i te ngongo, ā, ka tākaihia ki roto i tētahi rūma ma.
I taua wā anō, i hangaia e Zhongrui tētahi rūma ma kore-puehu ISO14644-1 Akomanga 5 i te wheketere tuarua mō te tākai i ngā ngongo EP.
Kua paahitia te whakamātautau mō te raina whakaputa oro hiko a Zhongrui, ā, kua hangaia nuitia, kua tukuna hoki ki ngā whenua o roto me tāwāhi. Kei te whakamahere te kamupene ki te whakanui ake i te raina whakaputa me te whakawhānui ake i te hanga o ngā paipa EP.
I tēnei wā, ko ngā whakaritenga mō ngā paipa EP i hangaia e Zhongrui kei waenganui i te O.D1/4"-40A, ko te paerewa whakatinanatanga e hangai ana ki te ASTM269, ā, ka taea e te taratara o roto te eke ki raro i te Ra0.25um. He maha ngā ahumahi kei te mākete Haina, pērā i te ahumahi haurua-ira, te taiwhanga, te pūngao o te rā. Kei te whānui haere hoki te ahumahi whakaputa me ngā mākete o tāwāhi, pērā i a Hingaiapore, Mareia, me Thailand.
