Gte whakawātea
Ngā Āhuatanga:
He tino pumau te konutea i te hau maroke, ā, kāore e ngāwari te huri i tōna tae. I roto i ngā taiao wai me te haumākū, ka tauhohe ki te hāora, ki te hauhā rānei hei hanga i ngā kiriata konutea warowaihā, kawakore rānei, ka ārai i te konutea kia kore e waikura tonu, ā, ka tiaki hoki.
He tino ngāwari te konutea ki te waikura i roto i ngā waikawa, ngā kawakore, me ngā whanariki. Ko te paparanga kua whakakikoruatia me whai maimoatanga whakakorekore. I muri i te whakakorekore i roto i te waikawa chromic, i te otinga chromate rānei, kāore te kiriata whakakorekore i hangaia e ngāwari te pā ki te hau makuku, ka nui ake te kaha ki te ārai i te waikura. Mō ngā wāhanga puna, ngā wāhanga angiangi (te matotoru o te pakitara <0.5m), me ngā wāhanga maitai e hiahia ana ki te kaha miihini teitei, me tango te hauwai, engari ko ngā wāhanga parahi me te koranu parahi kāore pea e hiahiatia te tango hauwai.
He iti te utu o te whakapūkara, he ngāwari te tukatuka, ā, he pai te pānga. He iti te kaha paerewa o te konutea, nō reira he paninga anodic te paninga konutea mō te maha o ngā konganuku.
He whānuitia te whakamahinga o te whakapūmau i roto i ngā āhuatanga hau me ētahi atu taiao pai. Engari kāore e pai hei whakamahi hei wāhanga waku.
Cwhakakikoruatia ki te kōroma
Ngā Āhuatanga: Mō ngā wāhanga e pā ana ki te āhuarangi moana, ki te wai tote rānei, ā, i roto i te wai wera neke atu i te 70℃, he pumau te paninga cadmium, he kaha te ātete ki te waikura, he pai te whakahinuhinu, ā, ka puhoi te rewa i roto i te waikawa hauwai waimeha, engari he tino wairewa i roto i te waikawa hauota, ā, kāore e wairewa i roto i te kawakore. Kāore hoki tōna waikura e wairewa i roto i te wai. He ngohengohe ake te paninga cadmium i te paninga konutea, he iti ake te pakaru o te hauwai, ā, he kaha ake te piri.
Heoi anō, i raro i ētahi āhuatanga hikohiko, he ataahua ake te paninga cadmium i te paninga konutea. Engari he paitini te hau e puta mai ana i te cadmium i te wā e rewa ana, ā, he paitini anō hoki ngā tote cadmium wairewa. I raro i ngā āhuatanga noa, ka mahi te cadmium hei paninga katotika i runga i te maitai, hei paninga anotika hoki i roto i ngā āhuarangi moana me ngā āhuarangi pāmahana teitei.
Ko te nuinga o te wā ka whakamahia hei tiaki i ngā wāhanga mai i te waikura o te hau e puta mai ana i te wai moana, i ngā otinga tote rite rānei, tae atu ki te kohu wai moana kua mākū. He maha ngā wāhanga o ngā ahumahi rererangi, moana, me te hiko, ngā puna, me ngā wāhanga miro kua whakakikoruatia ki te cadmium. Ka taea te whakakanapa, te whakapūkawa, me te whakamahi hei turanga peita, engari kāore e taea te whakamahi hei taputapu.
Whakakikoruatia te konupora
ngā āhuatanga:
He tino pumau te chromium i roto i ngā hau makuku, te kawakore, te waikawa hauota, te whanariki, ngā otinga warowaihā, me ngā waikawa waro, ā, he ngāwari te wairewa i roto i te waikawa hauwaiora me te waikawa whanariki wera kukū. I raro i te mahi a te iahiko tika, ki te mahi te paparanga chromium hei anode, ka ngāwari te wairewa i roto i te otinga houra kautika.
He kaha te piri o te paparanga chromium, he pakeke rawa, 800-1000V, he pai te ātete ki te kakahu, he kaha te whakaata mārama, ā, he nui te ātete ki te wera. Kāore e huri te tae i raro i te 480℃, ka tīmata te waikura i runga ake i te 500℃, ā, ka tino whakaiti i te pakeketanga i te 700℃Ko tōna ngoikoretanga he mārō, he pakarukaru, ā, he ngāwari te wetewete i te chromium, inā koa ka pāngia e ngā kawenga pānga tauutuutu. Ā, he porosity tōna.
He ngāwari te whakarewa chromium ki te whakakore i te hau, ka hua ake he kiriata whakakore, ā, ka huri te pūmanawa o te chromium. Nō reira, ka huri te chromium hei paninga katote ki runga i te rino.
Kāore i te pai te whakamahi tika i te whakakikoruatanga chrome hei paparanga ārai-waikura ki te mata o ngā wāhanga maitai. I te nuinga o te wā, ko te whakakikoruatanga hiko maha-paparanga (arā, ko te whakakikoruatanga parahi→whakakikorua nikara→(me te whakakikorua chromium) e hiahiatia ana hei whakatutuki i te kaupapa o te waikura
te ārai me te whakapaipai. E whakamahia whānuitia ana i tēnei wā hei whakapai ake i te ātete ki te kakahu o ngā wāhanga, te whakatika i ngā rahi, te whakaata mārama, me te rama whakapaipai.
Whakakikorua nikara
ngā āhuatanga:
He pai te pumau matū o te nikara i roto i te āhuarangi me te otinga kawakore, kāore e ngāwari te huri i tōna tae, ā, ka waikuratia anake i ngā pāmahana neke atu i te 600° C. Ka rewa mārire ki roto i te waikawa whanariki me te waikawa hauwaiora, engari he ngāwari te rewa ki roto i te waikawa hauota waimeha. Ka ngāwari te whakakore i roto i te waikawa hauota kukū, nō reira he ātete pai ki te waikura.
He tino pakari te whakakikorua nikara, he ngāwari ki te whakakanapa, he nui te whakaata mārama, ā, ka taea te whakapai ake i te āhua. Ko tōna ngoikoretanga he pōrohe tōna. Hei whakakore i tēnei ngoikoretanga, ka taea te whakamahi i ngā paninga whakarewa maha-paparanga, me te nikara hei paparanga waenga.
He paninga katote te nikara mō te rino, he paninga anote hoki mō te parahi.
He mea noa te whakamahi hei tiaki i ngā paninga whakapaipai hei ārai i te waikura, hei whakanui ake hoki i te ataahua. He mea tino pai te whakakikorua nikara i ngā hua parahi hei ārai i te waikura, engari nā te nui o te uara o te nikara, he maha ngā wā ka whakamahia ngā koranu parahi tine hei utu mō te whakakikorua nikara.
