Kōwhiringa Irahiko mō ngā Mita Rere Irahiko

He whānuitia te whakamahinga o ngā mita rere hikohiko (e mōhiotia ana ko ngā mita mag) hei ine i te rere o ngā wai kawe hiko i roto i ngā mahi ahumahi. E mahi ana ēnei mita i runga i te Ture a Faraday mō te whakapūtanga hikohiko, ā, kāore he wāhanga neke, nā reira he tino tika, he pono hoki mō ngā mahi ine rere. Ko tētahi wāhanga nui o ngā mita rere hikohiko ko te hiko, he mea nui ki te tukanga ine. Ko te whiriwhiri i te rauemi me te whirihoranga o te hikohiko e whakawhirinaki ana ki ētahi āhuatanga, pērā i te wai e inehia ana, ngā āhuatanga taiao, me te tika o te ine e hiahiatia ana.

Ngā Whakaaro Matua mō te Kōwhiringa Irahiko

1. Te Arahi o te Wai

Me kawe hiko te wai i ngā mita rere hiko-aukume kia pai ai te mahi a te ine rere. Ka kitea e ngā irahiko te ngaohiko e puta mai ana i te wā e haere ana te wai mā roto i te papa aukume o te mita rere. Nō reira, he mea nui te whiriwhiri i te rauemi irahiko tika kia tika ai ngā inenga, inā koa mēnā he iti, he teitei rānei te kawe hiko o te wai.

2. Ngā Rauemi Hiko

Me hototahi te rauemi e whakamahia ana mō ngā irahiko ki ngā āhuatanga matū o te wai kia mau ai te pakari me te pono. Ko ngā rauemi irahiko noa ko:

• Kowiri tira (316L):Ko te maitai kore waikura, he rauemi e whakamahia whānuitia ana mō ngā hikohiko, he tino ātete ki te waikura, ā, he pai hoki mō te whānuitanga o ngā wai, tae atu ki te wai, te paru, me te nuinga o ngā matū.

• Hāteloi (HC276):He koranu ātete-waikura a Hastelloy, e mōhiotia whānuitia ana mō tōna kaha ki te tu atu i ngā matū kino me ngā pāmahana tino kino.HC276e whakamahia ana i roto i ngā ahumahi pēnei i te rongoā, ngā matū, me te tukatuka kai, he mea noa te pānga ki ngā waikawa kaha, ngā kawakore, me ngā whakarewa. He ātete pai rawa atu ki te waikura, ā, he tino pai mō ngā taiao pēhanga teitei me te pāmahana teitei.

• Taitānia (Ta):He tino ātete ngā hikohiko titanium ki te waikura, ā, he pai mō ngā taiao uaua, inā koa ko ngā mea e uru ana ki te wai moana, ngā waikawa, me ētahi atu matū tino waikura. Ko te Tantalum (Ta) tētahi atu rauemi rite tonu me ngā āhuatanga ātete waikura tino pai, inā koa i roto i ngā wai waikawa me ngā wai tino tauhohe. He tino whai hua te Tantalum ina mahi tahi me ngā waikawa kaha, tae atu ki te waikawa whanariki, te waikawa hauwaiora, me ētahi atu matū tino waikura.

• Parahi (Pt):He tino ātete te konukawata ki te waikura matū, ā, he pai mō ngā wai tino kaha, engari he mea whakamahi noa i roto i ngā tono motuhake nā te mea he nui te utu. He pai ake ngā irahiko konukawata i roto i ngā taiao e hiahiatia ana te tino tika me te kore e taea te whakamahi i ngā matū, pērā i roto i ngā whare taiwhanga, i ētahi tono hauora me te tātari rānei. Nā te pumau me te ātete pai o te konukawata ki te whānuitanga o ngā matū, he pai mō ngā tono e hiahia ana ki te mahi tonu.

• Karāpiti, Waro rānei:Ka whakamahia ēnei rauemi i ētahi wā mō ngā mahi e pā ana ki ngā wai tino whakakoi, ngā wai kaha rawa rānei. He tino ātete hoki ngā irahiko karāpiti ki te waikura engari ka ngāwari pea te horo i raro i ētahi āhuatanga.

• Koura:E whakamahia ana ngā irahiko koura i ngā āhuatanga e hiahia ana kia tino tika, ā, e kitea nuitia ana i roto i ngā taiwhanga, i ngā tono tino motuhake rānei.

3. Whirihoranga Irahiko

Ka pāngia te tika me te aro o te mita rere e te whirihoranga hiko. Ko ngā whirihoranga hiko e rua e tino kitea ana ko:

• Whirihoranga Kotahi-Irahiko:Kei roto i tēnei whirihoranga tētahi irahiko mō te whakapā atu ki te wai, me tētahi atu mō te tohu tohutoro. He māmā ake, he iti ake te utu, engari he iti ake te tika o ētahi mahi.

• Whirihoranga Irahiko Maha (Irahiko Whā):Kei roto i tēnei hoahoa he maha ngā irahiko kua whakaritea kia porowhita huri noa i te paipa. Mā tēnei whirihoranga ka nui ake ngā inenga tika, inā koa i roto i ngā tono me ngā wai tino matotoru, ngā wai uaua rānei. Ka taea hoki e ia te āwhina ki te whakaiti i ngā hapa nā te pōraritanga me te pokanoa tohu.

4. Paninga me te Tiakitanga o te Irahiko

I ētahi wā, ka pania, ka tiakina rānei ngā irahiko hei whakapai ake i te mahi i roto i ngā tono motuhake. Hei tauira:

• Ngā paninga uku:Mō ngā wai tino whakakoi, waikura rānei, ka taea e ngā paninga uku te āwhina ki te tiaki i ngā irahiko mai i te kino me te whakaroa i tōna roanga mahi.

• Ngā Paninga PTFE, PFA rānei:Mō ngā matū kore-arahi hiko, ngā matū kaha rānei, ka whakamahia ngā paninga hiko i hangaia mai i ngā fluoropolymers pēnei i te PTFE, te PFA rānei hei whakarato whakamarumaru me te ārai.

5. Ātete ki te Pāmahana me te Pēhanga

Me whiriwhiri ngā irahiko i runga i ngā āhuatanga pāmahana me te pēhanga o te whakamahinga. Hei tauira, he pai ake ngā irahiko titanium, Hastelloy, me te platinum mō ngā whakamahinga pāmahana teitei me te pēhanga teitei ki te whakataurite ki ngā irahiko maitai kore waikura paerewa.

6. Rahi me te Whakamahinga o te Mita Rere

Ka pā anō hoki te rahi me te momo mita rere hikohiko (hei tauira, te mita katoa, te mita whakaurunga rānei) ki te kōwhiringa hiko. Ko ngā mita rere nui ake me whai hiko nui ake mō te mahi tino pai.

Whakamutunga

He mea nui te whiriwhiri i ngā irahiko mō ngā mita rere hikohiko hei whakarite i ngā inenga rere tika, inā koa i roto i ngā taiao ahumahi uaua. Mā te whakaaro ki te kawe hiko o te wai, ngā āhuatanga rauemi o ngā irahiko, te whirihoranga o ngā irahiko, me ngā āhuatanga whakahaere (pēnei i te pāmahana, te pēhanga, me te pānga matū), ka taea e koe te whiriwhiri i te rauemi me te whirihoranga irahiko e tika ana mō tō tono. Ko ngā rauemi pēnei i te HC276 (Hastelloy), Ta (Tantalum), me te Pt (Platinum) he ātete pai ki te waikura, ā, he tino pai mō ngā tono uaua. Ka taea e te whiriwhiringa tika o ngā irahiko te whakapai ake i te roa me te pono o te mita rere, ka waiho hei taonga nui i roto i ngā pūnaha ine rere ahumahi.
