Te Tātari i te Wai Waikawa mai i ngā Pourewa Horoi Āmonia – Tātari Kete

I. Papamuri Āhua Mahi: Ngā Wero Nui o ngā Wai Waikawa

Ko te tātari 8-inihi e whakamahia ana e te kiritaki o Iharaira e tukatuka ana i te wai waikawa mai i te pourewa horoi haukini, me te uara pH tata ki te 3. Ehara i te mea ko te 25% te haukini whanariki kei roto engari he iti noa iho ngā matūriki i puta i te horoinga hau. Ko tēnei taiao waikawa nui me te waikura e whakatakoto ana i ngā whakaritenga tino nui mō te ātete ki te waikura me te pumau hanganga o te rauemi tātari. Ko te noho mai o te haukini whanariki ka tere ake te waikura me te koroheketanga o ngā rauemi whakarewa noa, i te mea ka ārai pea ngā matūriki iri i roto i te tātari, ka pā ki te mahi pumau mō te wā roa o te taputapu. Nō reira, he mea nui kia whiriwhiria he taputapu tātari e tino urutau ana.

II. Taunakitanga Ritenga:Tātari Kete Panipani 316L + PTFE

Hei whakautu i ngā āhuatanga mahi uaua i runga ake nei, whai muri i te tātari ngaio me te kōwhiringa, ka tūtohu mātou ki te kiritaki o IharairaHe rauemi kowiri tira 316L kua whakakotahihia ki te tātari kete paninga PTFE (polytetrafluoroethylene)Ko ngā painga matua o tēnei otinga koia ēnei:

Tuatahi, ko te maitai kore waikura 316L, he rauemi ātete-waikura e whakamahia whānuitia ana i roto i te ao ahumahi, he iti ake te ihirangi waro i te maitai kore waikura 316 noa, he pai ake te ātete ki te waikura intergranular, ka taea te ātete pai ki te waikura tuatahi i roto i te taiao waikawa, ka whakarato i te hanganga turanga pakari mō te tātari. Tuarua,Paninga PTFEHe āhuatanga ahurei tōna, arā, "kāore e piri, e ātete ana ki te waikura, ā, e ātete ana ki te pāmahana teitei", e mōhiotia ana ko te "kīngi kirihou", ka taea te noho pumau i roto i te awhe pH o te 1-14 mō ngā waikawa kaha me ngā turanga kaha, ka wehea te pa tika i waenga i te otinga haukinia whanariki me te papa kowiri tira, ka whakaoti rapanga i te raruraru waikura o ngā mea waikura i runga i ngā taputapu, ā, ka roa ake te ora o te tātari.

I taua wā anō, ka hāngai te hoahoa hanganga o te tātari kete ki ngā whakaritenga tukatuka o ngā matūriki kei roto he wai. Ka whakamahia e te kete tātari kua hangaia ki roto ngā rauemi tātari tino tika, ka taea te aukati i te iti o ngā matūriki i roto i te wai, ka ārai i te aukati i te paipa; ā, he watea te hanganga kete mō te wetewete me te horoi, ka taea te whakaiti i ngā utu tiaki taputapu me te whakarite i te mahi tonu me te pumau o te pūnaha tātari, kia tino rite ki ngā āhuatanga mahi tuturu o te kiritaki.

III. Uara Otinga: Te Kōwhiringa Tino Pai mō te Haumaru me te Whai Hua

I roto i ngā āhuatanga mahi wai waikawa kino, he uaua ki te tu atu i ngā tātari maitai kore waikura noa i te mimiti o te reo mō te wā roa, he ngāwari ki te turuturu me te pakaru, ehara i te mea ka piki ake ngā utu whakakapinga taputapu engari ka pāngia hoki te ahunga whakamua o te whakaputanga nā te kati o ngā taputapu mō te tiaki. Ahakoa teTātari kete pania 316L + PTFE, mā te tiakitanga takirua o te rauemi me te paninga, ehara i te mea ka whakaoti noa i te raruraru waikura o te otinga ammonium sulfate engari ka whakahaere pai hoki i ngā poke matūriki, ka tutuki ai ngā taurangi rua o te tiakitanga me te whai huatanga.

Kua manatokohia tēnei otinga mā roto i ngā āhuatanga mahi ahumahi maha, ā, he wheako tono pakari, e whakarato ana i te tautoko tātari pono mō te tukanga whakaputa a te kiritaki o Iharaira, e āwhina ana i te kiritaki ki te karo i ngā mōrearea waikura taputapu, e whakaiti ana i ngā utu whakahaere me te tiaki, ā, koinei te kōwhiringa tino pai e whakakotahi ana i te haumaru, te whai hua, me te ōhanga.
