He aha te tikanga ka taea te whakamahi hei ārai i te waikura?

I te nuinga o te wā, ka taea te wehewehe i ngā tikanga ārai waikura ki ngā wāhanga matua e rua:

1.​Te whiriwhiri tika i ngā rauemi ātete-waikura me ētahi atu mahi ārai.​

2. Te whiriwhiri i ngā mahi tukanga me ngā hanganga taputapu e tika ana.

Mā te piripono ki ngā ture tukanga i roto i te hanga matū ka taea te whakakore i ngā āhuatanga waikura kore e hiahiatia. Heoi, ahakoa te whakamahi i ngā rauemi kounga teitei ātete-waikura, ka taea tonu e ngā tikanga whakahaere hē te arahi ki te waikura kino.

1. Ngā Ārai Waikura Kore-Pararopi;

I te nuinga o te wā, mā te tāpiri i tētahi iti o ngā aukati waikura ki tētahi taiao waikura ka taea te whakaroa i te waikura whakarewa. E toru ngā momo o ēnei aukati: ngā aukati kore-waro, ngā aukati waro, me ngā aukati āhua-kohu, he rerekē ngā tikanga o ia mea.

• Ngā Ārai Anodic (whakaroa i te tukanga anodic):

Kei roto i ēnei ko ngā matū whakahāora (chromates, nitrites, ions rino, me ētahi atu) e whakatairanga ana i te whakawāteatanga anodic, i ngā kaihoko kiriata anodic rānei (alkalis, phosphates, silicates, benzoates, me ētahi atu) e hanga ana i ngā kiriata tiaki i runga i te mata anode. Ka tauhohe tuatahi rātou i te rohe anodic, ka whakarei ake i te polarization anodic. I te nuinga o te wā, ka hangaia e ngā aukati anodic he kiriata tiaki i runga i te mata anode, he tino whai hua engari he mōrearea - ki te kore e ranea te horopeta ka hua ake he kapi kiriata kāore i oti, ka waiho he wāhi iti o te konganuku tahanga me te kiato o te iahiko anodic teitei, ka nui ake te tūponotanga o te waikura pitting.

• Ngā Ārai Katorika (e mahi ana ki te tauhohenga katorika):

Ko ētahi tauira ko te konupūmā, te konutea, te konupora, te parahi, me te manganese, e tauhohe ana ki ngā katote hauwaiwai i hangaia i te katote hei hanga hauwaiwai kore-rewa. Ka hangaia e ēnei he kiriata matotoru ki runga i te mata o te katote, ka aukati i te horapa o te hāora, ka whakanui ake i te porowhita kukū.

• Ngā Ārai Whakaranu (e pehi ana i ngā tauhohenga anodic me cathodic):

Me whakamātautau tonu ēnei hei whakatau i te horopeta tino pai.

;

2. Ngā Ārai Waikura Waro

Ka mahi ngā aukati rauropi mā te mimiti, ka hanga he kiriata matotoru e kore e kitea ki runga i te mata whakarewa e pehi ana i ngā tauhohenga anodic me cathodic i te wā kotahi (ahakoa he rerekē te whai huatanga). Ko ngā aukati rauropi noa ko ngā matū kei roto te hauota, te whanariki, te hāora, me te phosphorus. Ko ā rātou tikanga mimiti e whakawhirinaki ana ki te hanganga ngota, ā, ka taea te whakarōpū hei:

· Te mimiti hiko

· Te mimiti matū

· te mimiti o te hononga-π (irahiko kua tangohia te rohe)

He whānuitia te whakamahinga o ngā aukati rauropi, ā, he tere tonu te whanaketanga, engari he ngoikoretanga anō hoki ō rātou, pēnei i:

· Te poke o te hua (ina koa i roto i ngā mahi e pā ana ki te kai)—ahakoa he pai ki te kotahi te mahi

i roto i tētahi atu wāhanga whakaputa, tērā pea ka kino.

·Te aukati i ngā tauhohenga e hiahiatia ana (hei tauira, te whakaroa i te tangohanga o te kiriata i te wā e whakapūkarahia ana te waikawa).

3. Ngā Ārai Waikura Āhua-Kohu;

He matū tino pūngāwerewere ēnei kei roto ngā rōpū mahi aukati-waikura, e whakamahia ana hei tiaki i ngā wāhanga whakarewa i te wā e rongoatia ana, e kawe ana hoki (he maha ngā wā he totoka). Ka tukuna e ō rātou kohu ngā rōpū aukati hohe i roto i te makuku o te āhuarangi, ka piri ki te mata whakarewa hei whakaroa i te waikura.

Hei tāpiri, he aukati mimiti ēnei, arā, kāore e hiahiatia te tango i te waikura i mua i te mata whakarewa kua tiakina.
