Methyl tin stabilizer (nk'ibati ya mercaptan methyl) ni umuti urinda ubushyuhe w'icyatsi kibisi kandi udahumanya ibidukikije ukoreshwa cyane mu gutunganya PVC. Ibyiza byayo by'ingenzi birimo kudahumanya, gukorera mu mucyo mwinshi, kudahindagurika kw'ubushyuhe, no guhuza neza. Ahakurikira niho hakoreshwa cyane:
gupfunyika ibiryo
Ibikoresho bibonerana cyane: bikoreshwa mu gukora amacupa y'amazi y'ubutare, udusanduku tw'ibiryo tubonerana, amacupa yo kwisiga, n'ibindi, kugira ngo hirindwe "ibintu byo kwera" no kwemeza ko ibicuruzwa bibonerana kandi bifite ubwiza.
Icyemezo cy'umutekano: Yatsinze ibyemezo mpuzamahanga nka FDA muri Leta Zunze Ubumwe za Amerika na BGA mu Budage, hakurikijwe amabwiriza agenga ibikoresho byo gufata ibiryo.
Ibikoresho by'ubwubatsi n'imiyoboro
Imiyoboro ibonerana, nk'imiyoboro y'icyuma ya PVC n'imiyoboro itwara amazi, ifite ubushobozi bwo guhangana n'ikirere (≥ imyaka 10) kandi ifite impumuro nke.
Imiterere n'inzugi n'amadirishya: bikoreshwa mu gukora inzugi n'amadirishya by'icyuma cya pulasitiki, ibikoresho byo gushushanya, bisimbura ibintu bitera uburozi bwinshi.
Ibikoresho by'ubuvuzi
Ibikoresho by’umutekano mwinshi, nk'amashashi yo guterwamo amaraso n'udufuka tw'amaraso, bigomba kubahiriza amahame y’umutekano yo mu rwego rw’ubuvuzi.
Filime n'impapuro bibonerana cyane
Imirima ifite ubushobozi bwo gukora neza cyane, nka za firime zigabanya ubushyuhe n'amashuka bifite ubushobozi bwo kohereza urumuri bwa ≥ 91%, ikenera ubuziranenge buhamye kandi nta muhondo uhinduka mu gihe cyo gutunganya.
Ibikoresho by'ingenzi bya buri munsi n'ibikoresho bikora
Ibikoresho bya pulasitiki bibonerana cyane, nk'ibipfunyika byo kwisiga n'ibikoresho by'ibanze bikenerwa buri munsi, bifite ubushobozi bwo gutunganya amazi no kurwanya imvura.
Methyl tin stabilizer yabaye inyongeramusaruro idasimburwa mu gutunganya PVC ikomeye bitewe n’imiterere yayo mu bidukikije no gukoreshwa mu buryo bwagutse, cyane cyane mu nzego zikenerwa cyane nko mu biribwa no mu buvuzi.
