methyl tin stabilizer ke eng?

methyl tinstabilizers ke mofuta oa motsoako oa organotin o atisang ho sebelisoa e le li-stabilizers tsa mocheso ha ho etsoa polyvinyl chloride (PVC) le li-polymer tse ling tsa vinyl. Li-stabilizers tsena li thusa ho thibela kapa ho fokotsa ho senyeha ha mocheso oa PVC nakong ea ts'ebetso le ts'ebeliso, ka hona, ho matlafatsa ts'ebetso le ts'ebetso ea thepa. Lintlha tsa bohlokoa mabapi le methyl tin stabilizer ke tsena:

Sebopeho sa Lik'hemik'hale:Methyl tin stabilizers ke metsoako ea organotin e nang le lihlopha tsa methyl (-CH3). Mehlala e kenyelletsa methyl tin mercaptides le methyl tin carboxylates.

Mokhoa oa ho tsitsisa:Li-stabilizers tsena li sebetsa ka ho sebelisana le liathomo tsa chlorine tse lokollotsoeng nakong ea ho senyeha ha mocheso oa PVC. Li-methyl tin stabilizers li fokotsa li-radicals tsena tsa chlorine, li li thibela ho qala liketso tse ling tsa ho senyeha.

Lisebelisoa:Methyl tin stabilizers e sebelisoa haholo lits'ebetsong tse fapaneng tsa PVC, ho kenyeletsoa liphaephe, li-fittings, profiles, cables le lifilimi. Li sebetsa ka ho khetheha maemong a phahameng a mocheso, joalo ka a kopaneng nakong ea extrusion kapa ente e entsoeng.

Melemo:

Thermal Stability:Methyl tin stabilizers e fana ka botsitso bo sebetsang ba mocheso, e lumellang PVC ho mamella mocheso o phahameng nakong ea ts'ebetso.

Ho Boloka Mebala e Ntle:Ba kenya letsoho ho boloka botsitso ba 'mala oa lihlahisoa tsa PVC ka ho fokotsa ho fifala ho bakoang ke ho senyeha ha mocheso.

Haholo-holo Heat Aging Resistance:Methyl tin stabilizers e thusa lihlahisoa tsa PVC ho hanela ho senyeha ha nako e ntse e ea ha li pepesehetse mocheso le maemo a tikoloho.

Mehopolo ea Taolo:Le hoja e sebetsa hantle, tšebeliso ea metsoako ea organotin, ho akarelletsa le methyl tin stabilizers, e tobane le tlhahlobo ea taolo ka lebaka la mathata a tikoloho le bophelo bo botle bo amanang le metsoako ea tin. Libakeng tse ling, lithibelo tsa taolo kapa lithibelo li behiloe ho li-stabilizer tse itseng tsa organotin.

Mekhoa e meng:Ka lebaka la liphetoho tsa taolo, indasteri ea PVC e hlahlobile mefuta e meng e tsitsitseng ea mocheso e nang le tšusumetso e fokolang ea tikoloho. Li-stabilizers tse thehiloeng ho calcium le mefuta e meng eo e seng ea tin li ntse li sebelisoa haholo ho arabela melaoana e ntseng e fetoha.

Ho bohlokoa ho hlokomela hore litlhokahalo tsa taolo li ka fapana ho ea ka libaka, 'me basebelisi ba lokela ho latela melao le litataiso tsa lehae ha ba khetha le ho sebelisa li-stabilizer tsa PVC. Kamehla buisana le bafani ba thepa, litataiso tsa indasteri, le balaoli ba amehang ba taolo bakeng sa lintlha tsa morao-rao mabapi le likhetho tsa botsitso le ho latela melao.
