Whakapūmau Tin Metil
Ko te Methyl Tin Stabilizer tētahi o ngā mea whakaū wera. Ko ngā āhuatanga matua ko te tino whai hua, te tino mārama, te ātete wera pai, me te ātete ki te parahanga whakamomona. E whakamahia ana i roto i ngā kiriata takai kai me ētahi atu hua PVC mārama. He tino pai te aukati i te mahi tae-mua o ngā hua PVC i te wā tukatuka, he tino ātete ki te UV me te pumau mō te wā roa, he pai te rere, he pai te pupuri tae i te wā tukatuka, me te pai o te mārama o te hua. Ina koa, kua eke tōna pumau photothermal ki te taumata rangatira o te ao, ā, ka taea e ia te pupuri i te whakamahinga anō o te tukatuka tuarua. He whānuitia te whakamahinga o te organotin stabilizer i roto i te umanga tukatuka kapia polyvinyl chloride (PVC), he pai mō te calendering PVC, te extrusion, te pupuhi, te werohanga me ētahi atu tukanga tukatuka, he tino pai mō ngā rongoā, te kai, ngā paipa wai inu me ētahi atu tukanga tukatuka PVC.

E rua ngā momo matua o ngā whakaū tote mata, arā, ko ngā monomer me ngā hiato, ā, ko ngā whakaū tote mata te nuinga o te wā e whakamahia ana hei whakaū matua i Haina. Ka whakamahia e te whakaū wera tote mata hiato te hangarau tauhohenga tahi hei whakaranu i ngā tote e toru, ngā tote e rua me te hopi whakarewa i roto i te pūnaha tauhohenga me te rahi o te witi taiao tuatahi me ngā momo hinu whakahinuhinu hei whakarite i te marara katoa o te whakaū wera i roto i te pūnaha PVC, ā, i te wa ano, nā te whakakotahitanga me te hinu whakahinuhinu hei hanga i te āhua kirikiri, ka karohia hoki te paitini i puta mai i te puehu mata. Kei roto i ngā whakaū tote mata hiato ngā wāhanga whakaū wera me te hinu whakahinuhinu e hiahiatia ana mō te tukatuka, ā, e kiia ana ko ngā whakaū wera kapi katoa.

Kaiwhakaū Konupūmā me te Konutea
Ka hangaia ngā whakaū konupūmā me te konutea mā te whakamahi i tētahi tukanga whakakotahi motuhake mō ngā tote konupūmā, ngā tote konutea, ngā hinu whakahinuhinu, ngā antioxidants, me ētahi atu hei wāhanga matua. Ehara i te mea ka taea anake te whakakapi i ngā whakaū paitini pērā i te mata me te cadmium me ngā organotin, engari he pai hoki te pumau o te wera, te pumau o te māramatanga me te māramatanga me te kaha tae. Mā te kapia PVC, he pai te horapa o te tukatuka, te hototahitanga, te rere o te tukatuka, te whānui o te urutau, te mutunga mata pai o te hua; He pai te pumau o te wera, he iti te tae tīmatanga, kāore he ua; Kāore he konganuku taumaha me ētahi atu wāhanga paitini, kāore he āhuatanga whakamomona; He roa te wā whakamātautau whero o Congo, he pai te whakamarumaru hiko, kāore he poke, he ātete huarere tino pai; He whānui te whānuitanga o te tono, he kaha te mahi, he iti te horopeta, he maha ngā mahi; I roto i ngā hua mā, he pai ake te mā i ērā o ngā hua rite.
