Ina tae mai kidimethyltin dichloride(DMCT) me te nama CAS 753-73-1, kāore pea te marea i te mōhio ki tōna ingoa, engari he mahi nui tāna i roto i ngā hononga matua maha o te hanga ahumahi. Hei matū organotin nui, ko te DMCT, me ōna āhuatanga matū ahurei, he mahi nui tā te dimethyltin dichloride i roto i ngā mara pēnei i te tiaki whakarewa, te tukatuka kirihou, me te hanga rauemi kounga teitei. Nō nā tata nei, me te whakapai ake i ngā tono ahumahi e pā ana, kua whakanuia ake tōna uara tono, ā, he rauemi matua e akiaki ana i te whanaketanga o ngā ahumahi maha.

He aha te whakamahinga o te Dimethyltin dichloride?
Ngā tono matua odimethyltin dichloride(CAS Nama 753-73-1) e aro nui ana ki te tiaki rauemi, te tukatuka kirihou me ngā rauemi motuhake, ā, ka taea te whakarōpū motuhake ki ngā wāhanga matua e toru.
I te mara o te tiaki whakarewa: "Te whakakakahu i ngā kākahu tiaki" mō ngā koranu konupora hei whakahaere i te whanaketanga o te umanga mama
I roto i ngā mara e tino hiahiatia ana te whakamama i ngā rauemi, pērā i te rererangi me te hanga waka, he tino paingia ngā koranu konupora nā te mea he māmā, he kaha hoki. Heoi, kua waiho te āhuatanga ngāwari ki te waikura o ngā koranu konupora hei "aukati" e aukati ana i tā rātou tono nui. I tēnei wā, ko te putanga mai o te DMCT i whakarato i tētahi otinga whai hua ki tēnei raruraru uaua.
E ai ki ngā raraunga ahumahi, ko te hiahia ā-rohe mō te DMCT e whakamahia ana i roto i te tiakitanga waikura o te konupora konupora ka eke ki te 6,000 tana i te tau 2024, e tohu ana i te tipu tau-ki-te-tau o te 12%. I te pikinga tonu o te hiahia mō ngā rauemi mama i roto i ngā ahumahi pēnei i ngā waka pūngao hou me ngā waka rererangi kore tangata, e matapaetia ana ka noho tonu te tere tipu o te hiahia mō te DMCT i tēnei mara ki runga ake i te 10% i roto i ngā tau e rua e whai ake nei, ka tautoko kaha i te tono tauine nui o te ahumahi konupora konupora.
Ahumahi tukatuka kirihou: Ko ngā mea whakaū PVC te "kaha matua", e whakarite ana i te kounga me te haumaru o te hua
Ko te Polyvinyl chloride (PVC), hei tētahi o ngā kirihou whānui me te putanga nui rawa atu o te ao, he whānuitia te whakamahinga o te dimethyl tin Dichloride i roto i ngā mara pēnei i ngā paipa, ngā kōtaha, me ngā kiriata. Heoi, i te wā e tukatukahia ana, e whakamahia ana hoki te PVC, ka ngawari ki te pirau nā ngā āhuatanga pēnei i te pāmahana teitei me te hihi o te rā, ka hua ake te tae ke, te whakapakeke me te heke o te mahi o ngā hua. Ko te dimethyltin dichloride DMTC, hei takawaenga matua o ngā whakaū wera PVC, ka taea te aukati i te tauhohenga pirau o te PVC, ā, ka noho hei "kaha matua" hei whakarite i te kounga me te haumaru o ngā hua PVC.
Te hanga rauemi kounga teitei: Whakakahangia e ngā rauemi o mua, e āwhina ana i te auahatanga i roto i ngā ahumahi hikohiko me te pūngao hou
Haunga ngā mara tono tuku iho, kei te puta haere te tono o te dimethyltin dichloride DMCT i roto i te hanga rauemi teitei, inā koa i roto i ngā ahumahi hikohiko me te pūngao hou, kei reira tonu te tūhuratanga o tōna uara hei rauemi mua.
I roto i te ao o te whakaaturanga hiko, ko ngā kiriata waikura tine mārama he wāhanga matua o ngā hua pēnei i ngā whakaaturanga karaihe wai me ngā mata pā. Whai muri i te tukatuka mā ngā tikanga motuhake,dimethyltin dichloride DMCT ka taea te whakamahi hei rauemi matua kounga teitei mō te hanga kiriata waikura tine mārama. Ki te whakatauritea ki ngā matua tuku iho, he nui ake te kawe hiko me te tuku mārama o ngā kiriata i hangaia mai i te DMCT hei rauemi mata, ā, ka taea e ēnei te whakapai ake i te kounga pikitia me te aro pā o ngā hua whakaaturanga. I tēnei wā, kua whakamahia whānuitia tēnei hangarau i roto i ngā umanga whakaaturanga rongonui o te motu, e whakatairanga ana i te ahumahi whakaaturanga o te motu kia whanake ki te kounga teitei ake.
I roto i te ao o te pūngao hou, he pai hoki te kaha o te dimethyl tin dichloride. Kua whakaatuhia e ētahi whare rangahau ka taea te whakamahi i ngā matū organotin i ahu mai i te DMCT ki te whakarite rauemi hiko mō ngā pūtau rā, e tumanakohia ana ka whakarei ake i te whai huatanga o te hurihanga hiko whakaahua o ngā pūtau rā. I tēnei wā, kua uru te hangarau e tika ana ki te wāhanga whakaputa whakamātautau. Mena ka whakamahia i roto i te ahumahi a meake nei, ka werohia he kaha hou ki te whanaketanga o te umanga pūngao hou.
E tohu ana ngā tohunga ahumahi, nā te whanaketanga tonu o te hangarau me te tere o te whanaketanga o ngā ahumahi e pā ana, kua piki ake ngā mara tono oDMCTka whakawhānuihia anō. Heoi, i te wā kotahi, me aro atu hoki ki ngā take tiaki taiao i te wā e hangaia ana, e whakamahia ana hoki. Mā te auahatanga hangarau, me whakatairanga te umanga DMCT kia whanake i roto i te huarahi matomato me te pumau, kia pai ake ai te whakamana i te whanaketanga o ngā momo ahumahi.'
