China Yopanda poizoni ya Methyl Tin Stabilizer ya PVC, pepala la PVC, zinthu zowonekera bwino Wopanga ndi Wogulitsa

Chokhazikika cha Methyl Tin chosaopsa cha filimu ya PVC, pepala la PVC, zinthu zowonekera bwino Chithunzi Chowonetsedwa

Chokhazikika cha Tin ya Methyl

Kufotokozera Kwachidule:

Methyl Tin Stabilizer ndi imodzi mwa zolimbitsa kutentha. Makhalidwe akuluakulu ndi kugwira ntchito bwino kwambiri, kuwonekera bwino kwambiri, kukana kutentha kwambiri, komanso kukana kuipitsidwa ndi vulcanization. Imagwiritsidwa ntchito makamaka mu filimu yopaka chakudya ndi zinthu zina zowonekera za PVC. Ili ndi choletsa chachikulu cha utoto wa zinthu za PVC panthawi yokonza, kukana bwino kwa UV komanso kukhazikika kwa nthawi yayitali, kusinthasintha kwabwino, kusunga bwino utoto panthawi yokonza, komanso kuwonekera bwino kwa zinthu. Makamaka, kukhazikika kwake kwa photothermal kwafika pamlingo wotsogola padziko lonse lapansi, ndipo imatha kusunga bwino kugwiritsanso ntchito kwachiwiri. Organotin stabilizer imagwiritsidwa ntchito kwambiri mumakampani opanga utomoni wa polyvinyl chloride (PVC), yoyenera kupangira ma calender a PVC, extrusion, blow molding, injection molding ndi njira zina zopangira utomoni, makamaka yoyenera mankhwala, chakudya, mapaipi amadzi akumwa ndi njira zina zopangira PVC. (Cholimbitsa ichi sichiyenera kugwiritsidwa ntchito ndi lead, cadmium ndi zina zolimbitsa.) Zambiri zimachepa.

Chonde pitani pansi kuti mudziwe zambiri!

Zolimbitsa kutentha (PVC) ndi ma polima ena okhala ndi chlorine. Methyl tin stabilizer ndi polima yopanda mawonekedwe. Chifukwa cha kapangidwe kake kapadera ka PVC, imawola mosalekeza kutentha kwa kukonza, zomwe zimapangitsa mtundu kukhala wakuda, kuchepetsa mphamvu zakuthupi ndi zamakaniko, komanso kutaya mtengo wogwiritsira ntchito. Zolimbitsa kutentha zimapangidwa ndikupangidwa kuti zithetse vutoli. Malinga ndi kapangidwe ka mankhwala osiyanasiyana, zolimbitsa kutentha zimagawidwa makamaka m'magawo a mchere wa lead, sopo wachitsulo, organic tin, rare earth, organic antimony ndi organic assistant stabilizers. Mitundu yosiyanasiyana ya zinthu ili ndi mawonekedwe awoawo ogwirira ntchito ndipo ndi yoyenera minda yosiyanasiyana. M'zaka zaposachedwa, makampani a PVC apita patsogolo mwachangu, zomwe zapangitsa kuti makampani olimbitsa kutentha apite patsogolo mwachangu. Kumbali imodzi, chiphunzitso cha zolimbitsa kutentha chikukhala changwiro kwambiri, zomwe zimapangitsa kuti pakhale zinthu zabwino kwambiri za PVC; kumbali ina, zinthu zatsopano zoyenera minda yosiyanasiyana zikupangidwa nthawi zonse, makamaka chifukwa cha poizoni wa mchere wa lead ndi zitsulo zolemera. Chifukwa chake ndikuti makampani opanga PVC amasankha choyamba zolimbitsa kutentha zopanda poizoni.

Pakupanga makampani opanga zinthu za PVC, kuwonjezera pa kufunikira zolimbitsa kutentha kuti zikwaniritse kukhazikika kwa kutentha, nthawi zambiri zimafunika kukhala ndi kusinthasintha kwabwino, kukana nyengo, kusinthasintha kwa utoto, kukhazikika kwa kuwala, komanso zofunikira kwambiri pa fungo lawo ndi kukhuthala kwawo. Nthawi yomweyo, pali mitundu yambiri ya zinthu za PVC, kuphatikizapo mapepala, mapaipi, ma profiles, ma blow moldings, ma injection moldings, zinthu za thovu, ma phala a phala, ndi zina zotero. Ma formula ambiri opangira zinthu za PVC amafunika kupangidwa ndi makampani omwewo. Chifukwa chake, kusankha zolimbitsa kutentha panthawi yokonza PVC ndikofunikira kwambiri. Zolimbitsa kutentha za Organotin ndi zolimbitsa kutentha zomwe zapezeka mpaka pano.
