Whakapūmau Tin Metil

Ngā pūmau wera (PVC) me ētahi atu pūmua kei roto he chlorine. He pūmua teitei kore-ahua te pūmau tine methyl. Nā te hanganga motuhake o te PVC, ka pirau tonu i te pāmahana tukatuka, ka pouri ake te tae, ka whakaiti i ngā āhuatanga ā-tinana me ngā āhuatanga miihini, ā, ka ngaro te uara whakamahi. Ka whakawhanakehia, ka hangaia hoki ngā pūmau wera hei whakaoti i tēnei raruraru. E ai ki ngā hanganga matū rerekē, ka wehea ngā pūmau wera ki ngā tote mata, ngā hopi whakarewa, te tine waro, te whenua onge, te antimony waro me ngā pūmau āwhina waro. He āhuatanga mahi motuhake ngā momo hua rerekē, ā, he pai mō ngā mara rerekē. I ngā tau tata nei, kua tere te whanaketanga o te umanga PVC, ā, kua tere te whanaketanga o te umanga pūmau wera. I tētahi taha, kei te tino pai haere te ariā o ngā pūmau wera, e whakarato ana i ngā tikanga mō te whiwhi hua PVC pai ake; i tētahi atu taha, kei te whanake tonu ngā hua hou e tika ana mō ngā mara rerekē, inā koa nā te paitini o ngā tote mata me ngā konganuku taumaha. Ko te take he tuatahi ka whiriwhiri ngā umanga tukatuka PVC i ngā pūmau wera kore-paitini.

I roto i te hanga o ngā umanga tukatuka PVC, haunga te hiahia ki ngā mea whakaū wera hei whakatutuki i te pumau wera, he maha tonu ngā wā e hiahiatia ana kia pai te tukatuka, te ātete ki te huarere, te tae tuatahi, te pumau mārama, me ngā whakaritenga pakari mō ō rātou kakara me te matotoru. I taua wā anō, he maha ngā momo hua PVC, tae atu ki ngā pepa, ngā paipa, ngā kōtaha, ngā whakakikorua pupuhi, ngā whakakikorua werohanga, ngā hua pahuka, ngā kapia whakapiri, me ētahi atu. Ko te nuinga o ngā tauira tukatuka o ngā umanga e hanga ana i ngā hua PVC me whakawhanake e ngā umanga ake. Nō reira, he mea tino nui te whiriwhiri i ngā mea whakaū wera i te wā e tukatuka ana i te PVC. Ko ngā mea whakaū wera organotin he mea whakaū wera kua kitea tae noa mai ki tēnei wā.
