Kodi methyl tin stabilizer ndi chiyani?

Chitini cha MethylZokhazikika ndi mtundu wa organotin compound yomwe imagwiritsidwa ntchito kwambiri ngati zokhazikika pakupanga polyvinyl chloride (PVC) ndi ma vinyl polymer ena. Zokhazikika izi zimathandiza kupewa kapena kuchepetsa kuwonongeka kwa kutentha kwa PVC panthawi yokonza ndi kugwiritsa ntchito, motero zimawonjezera kulimba ndi magwiridwe antchito a chipangizocho. Nazi mfundo zazikulu zokhudzana ndi zokhazikika za methyl tin:

Kapangidwe ka Mankhwala:Methyl tin stabilizers ndi mankhwala a organotin okhala ndi magulu a methyl (-CH3). Zitsanzo zikuphatikizapo methyl tin mercaptides ndi methyl tin carboxylates.

Njira Yokhazikitsira Zinthu:Zokhazikikazi zimagwira ntchito polumikizana ndi maatomu a chlorine omwe amatulutsidwa panthawi ya kuwonongeka kwa kutentha kwa PVC. Zokhazikika za methyl tin zimathetsa ma radical a chlorine awa, kuwaletsa kuyambitsa kuwonongeka kwina.

Mapulogalamu:Zolimbitsa chitsulo cha methyl zimagwiritsidwa ntchito kwambiri pa ntchito zosiyanasiyana za PVC, kuphatikizapo mapaipi, zolumikizira, ma profiles, zingwe, ndi mafilimu. Zimagwira ntchito bwino kwambiri pa kutentha kwambiri, monga zomwe zimakumana nazo panthawi yotulutsa kapena kupanga jekeseni.

Ubwino:

Kukhazikika Kwambiri kwa Kutentha:Zolimbitsa thupi za methyl tin zimathandiza kuti kutentha kukhale kolimba, zomwe zimathandiza PVC kupirira kutentha kwambiri panthawi yokonza.

Kusunga Utoto Wabwino:Zimathandizira kusunga mtundu wa zinthu za PVC mwa kuchepetsa kusintha kwa mtundu komwe kumachitika chifukwa cha kutentha.

Kukana Kutentha Kwambiri:Zolimbitsa chitsulo cha methyl zimathandiza zinthu za PVC kuti zisawonongeke pakapita nthawi zikakumana ndi kutentha ndi nyengo.

Zoganizira Zokhudza Malamulo:Ngakhale kuti kugwiritsa ntchito mankhwala a organotin, kuphatikizapo methyl tin stabilizers, kwayang'aniridwa ndi malamulo chifukwa cha nkhawa zokhudzana ndi chilengedwe ndi thanzi zomwe zimagwirizanitsidwa ndi mankhwala a tin. M'madera ena, malamulo kapena ziletso zaperekedwa pa mankhwala enaake okhazikika a organotin.

Njira zina:Chifukwa cha kusintha kwa malamulo, makampani opanga PVC afufuza njira zina zotetezera kutentha zomwe sizikhudza chilengedwe. Zotetezera kutentha zochokera ku calcium ndi njira zina zosakhala za tin zikugwiritsidwa ntchito kwambiri poyankha malamulo omwe akusintha.

Ndikofunikira kudziwa kuti zofunikira pa malamulo zingasiyane malinga ndi chigawo, ndipo ogwiritsa ntchito ayenera kutsatira malamulo ndi malangizo am'deralo posankha ndikugwiritsa ntchitoZokhazikika za PVCNthawi zonse funsani ogulitsa, malangizo a makampani, ndi akuluakulu olamulira kuti mudziwe zambiri zaposachedwa za njira zokhazikitsira zinthu komanso kutsatira malamulo.
