Te "Kaitiaki" o ngā Konganuku Utu Nui: He aha i Whakamahia Whānuitia ai ngā Dithiophosphates (Ngā Kaihoko Pango) i roto i te Whakarewatanga Kohuke

I roto i ngā whare whakapūmau, e mōhiotia whānuitia ana ngā xanthates hei kaikohi kaha me te kaha ki te kohikohi whānui. Heoi, hei whakapai ake i te whakaora i te koura me te hiriwa, hei wehewehe rānei i te mata mai i te konutea, he maha ngā wā ka tūtohu ngā tohunga whakarewa mohio i ngā dithiophosphates, e mōhiotia whānuitia ana ko ngā "kaihoko pango" nā te āhua wai pouri, he maha ngā wā ka matotoru. Ahakoa te āhua koretake, he pai ngā painga o ēnei matū hei rongoā i ngā konganuku utu nui me ngā konganuku sulfide matatini.

I. He aha ngā Dithiophosphates (Ngā Ākena Pango)?

He momo kaikohi matū ngā dithiophosphates ki ngā xanthates. Ahakoa he kaha ngā xanthates, he kaikohi kore-whiriwhiri e rere ana i ngā whanariki rino (pyrite), he whiriwhiri ake ngā dithiophosphates. He pumau ake hoki ō rātou matū, ā, he iti ake te ngāwari ki te pirau.

II. Ngā Painga Matua

1. He iti te hononga ki te Pyrite: He painga nui tēnei mō te wehewehe i te mata, i te parahi rānei i te pyrite. Ka rere te pyrite mā roto i ngā xanthates, engari he ngoikore te kaha o ngā dithiophosphates ki te kohikohi ki te pyrite, ā, ka māmā ake te wehenga.
2. Te Kaha ki te Kohikohi i te Koura me te Hiriwa: Ka hangaia e ngā Dithiophosphates he hononga matū pumau ki ngā mata o te konganuku utu nui, ā, he tino whai hua mō te whakaora i te koura, te hiriwa, me te konukawata. He maha ngā whare tukatuka koura e tāpiri ana i ngā dithiophosphates (hei tauira, Aero 238, ammonium dibutyl dithiophosphate rānei) ki ngā ara iahiko scavenger, ki ngā ara iahiko horoi rānei hei whakanui ake i te whakaora i te konganuku utu nui.
3. Ngā Āhuatanga Whakahuka: He maha ngā dithiophosphates (hei tauira, Aero 238) he kaha whakahuka ā-roto, e whakaiti ana, e whakakore ana rānei i te hiahia mō ētahi atu whakahuka (pērā i te MIBC, i te hinu paina rānei). He pakarukaru te huka e puta mai ana, ā, he tere te pakaru.

III. Ngā Momo Noa

• Aero 238 (Alkyl Dithiophosphate): He momo wai noa, he āhuatanga kohikohi, he āhuatanga whakapūpū hoki. He pai mō te wehenga mata-konutea me te whakaora parahi-koura. He kakara kaha, ā, he āhuatanga waikura.
• Ammonium Dibutyl Dithiophosphate: E wātea ana hei paura mā (ahakoa te ingoa "pango"). Kāore e waikura, he iti te kakara, he wairewa ki te wai. He pai mō ngā konganuku hiriwa me ngā konganuku parahi ātete-wera, inā koa ko ngā wāhi e aro nui ana ki te taiao.
• Diphenyl Dithiophosphate: Kāore i te tino kitea, he kaha te kohikohi. Whakamahia mō te galena ātete waikura, te galena pai rānei.

IV. Ngā Whakaaro Whakahaere

• Mōrearea Waikura: He waikawa, he waikura hoki ngā dithiophosphates wai (hei tauira, Aero 238). Whakamahia ngā rauemi ātete-waikura mō ngā raina inenga. Me mau ngā kaiwhakahaere i ngā PPE tika.
• Kaua e nui rawa te horomanga: Ka nui rawa te huka ka puta mai i te horomanga, ka nui rawa te taunga ("kawe atu") mai i ngā pūtau mānu. Whakatikatikahia te horomanga me te āta tupato, inā koa ka whakamahia he mea whakahuka.
• Ngā Mahi Āta Pūhoi: He puhoi ake te mahi a ngā Dithiophosphates i ngā xanthates, ā, he roa ake te wā whakatikatika e hiahiatia ana kia pai ai te mahi.

Whakamutunga

I roto i ngā mahi whakapūmau hou, ehara ngā dithiophosphates i te whakakapi mō ngā xanthates engari he tauhohenga tāpiri. Ko tētahi rautaki noa ko te whakamahi i ngā xanthates mō te whakaora papatipu i roto i te whakapūmau taratara, me ngā dithiophosphates mō ngā wāhanga ma hei whakarei ake i te whiriwhiri me te whakaora i ngā konganuku utu nui.
