Tīni metilKo ngā whakapūmau he momo matū organotin e whakamahia whānuitia ana hei whakapūmau wera i roto i te hanga o te polyvinyl chloride (PVC) me ētahi atu polymer vinyl. Ka āwhina ēnei whakapūmau ki te aukati, ki te whakaiti rānei i te pirau wera o te PVC i te wā e tukatukahia ana, e whakamahia ana hoki, ā, ka whakarei ake i te pakari me te mahi o te rauemi. Anei ngā kōrero matua mō ngā whakapūmau methyl tin:
Hanganga Matū:Ko ngā mea whakaū tine methyl he matū organotin kei roto ngā rōpū methyl (-CH3). Ko ētahi tauira ko ngā mercaptides tine methyl me ngā carboxylates tine methyl.
Tikanga Whakapūmau:Ka mahi ēnei whakaū mā te taunekeneke ki ngā ngota chlorine i tukuna i te wā o te pirau wera o te PVC. Ka whakakorea e ngā whakaū methyl tin ēnei rauropi chlorine, ka ārai i a rātou kei tīmata i ngā tauhohenga pirau anō.
Ngā tono:He whānuitia te whakamahinga o ngā whakaū tine methyl i roto i ngā momo mahi PVC, tae atu ki ngā paipa, ngā hononga, ngā kōtaha, ngā taura, me ngā kiriata. He tino whai hua ēnei i roto i ngā āhuatanga tukatuka pāmahana teitei, pērā i ngā mea e tūpono ana i te wā e whakaputa ana i te extrusion, i te werohanga rānei.
Ngā Painga:
Te Pūmautanga Wera Teitei:Ka whakaratohia e ngā whakaū tine methyl te whakaū wera whai hua, ka taea ai e te PVC te tu atu i ngā pāmahana teitei i te wā e tukatukahia ana.
Te Pupuri Tae Pai:Ka whai wāhi atu rātou ki te pupuri i te pumau o te tae o ngā hua PVC mā te whakaiti i te taekore i puta mai i te pirau wera.
Ātete Pai ki te Pakari Wera:Ka āwhina ngā whakaū tine methyl i ngā hua PVC kia ātete ki te pirau i roto i te wā ina pāngia e te wera me ngā āhuatanga taiao.
Ngā Whakaaro Whakahaere:Ahakoa te whai huatanga, kua tirotirohia te whakamahinga o ngā matū organotin, tae atu ki ngā mea whakaū tine methyl, e ngā ture nā runga i ngā āwangawanga taiao me te hauora e pā ana ki ngā matū tine. I ētahi rohe, kua whakatakotoria he here, he aukati rānei e ngā ture mō ētahi mea whakaū tine.
Ngā Huarahi kē atu:Nā ngā panonitanga ture, kua tūhuratia e te umanga PVC ētahi atu momo whakaū wera e whakaiti ana i te pānga ki te taiao. Kei te piki haere te whakamahinga o ngā momo whakaū e ahu mai ana i te konupūmā me ētahi atu momo whakakapi kore-tine hei whakautu i ngā ture e whanake haere ana.
He mea nui kia mōhiotia he rerekē pea ngā whakaritenga ture i ia rohe, ā, me piri ngā kaiwhakamahi ki ngā ture me ngā aratohu ā-rohe i te wā e whiriwhiri ana, e whakamahi ana hoki.Ngā whakaū PVCMe kōrero tonu ki ngā kaiwhakarato, ki ngā aratohu ahumahi, me ngā mana whakahaere e tika ana mō ngā mōhiohio hou e pā ana ki ngā kōwhiringa whakaū me te tutuki i ngā whakaritenga.
