Polyvinyl chloride (PVC) ndi polima wa vinyl chloride monomer (VCM) opangidwa ndi peroxide, mankhwala awo ndi oyambitsa ena kapena mwaulere wopanga ma polymerization reaction limayendera kuwala ndi kutentha. Vinyl chloride homo polima ndi vinyl chloride co polymer amatchedwa vinyl chloride resin.
PVC inali pulasitiki yayikulu kwambiri padziko lonse lapansi ndipo imagwiritsidwa ntchito kwambiri. Amagwiritsidwa ntchito kwambiri popanga zomangamanga, zopangira mafakitale, zofunikira tsiku ndi tsiku, zikopa zapansi, njerwa zapansi, zikopa zopangira, mapaipi, mawaya ndi zingwe, kulongedza kanema, mabotolo, zopangira thobvu, zinthu zosindikiza, ulusi ndi zina zambiri.
PVC ndi mawonekedwe amorphous ufa woyera, wokhala ndi digiri yotsika ya nthambi. Kutentha kwake kwa galasi ndi 77 ~ 90 ℃, ndikuyamba kuwola at170 ℃. Pakadali pano imakhala ndi bata ndi kutentha pang'ono: imawola ndikupanga hydrogen chloride pamwambapa 100 ℃ kapena itakhala nthawi yayitali pakuwala kwa dzuwa, ndikupanganso zokha, zomwe zimayambitsa kupindika ndi kuchepa kwa thupi ndi makina, , stabilizer kapena zowonjezera zina ziyenera kuwonjezeredwa kukonza kukhazikika kwa PVC.
Kampaniyo imatha kupereka zowonjezera zowonjezera za PVC:
| KUGawanika | PRODUCT | CAS | MTUNDU WA COUNTER | NTCHITO |
| WOSANGALATSA | YIHOO AN245DW | 36443-68-2 35% 7732-18-5 65% | SONOX 2450DW | Amagwiritsidwa ntchito kwambiri pakupanga, labala wopangira, POM homopolymer ndi copolymer, PU, PA, PET, MBS, ndi PVC. |
| YIHOO AN333 | 77745-66-5 | JP333E | Phenol-free antioxidant, yogwiritsidwa ntchito ngati othandizira kutentha kwa PVC, kukonza utoto ndi kuwonekera poyera kwa zinthu za PVC. Itha kugwiritsidwanso ntchito popangira zida za mphira ndi PU kuti zinthu zisakwane. | |
| YIHOO HP136 | 181314-48-7 | Itha kupereka hydrogen yogwira kuti ipangitse phenolic antioxidant yotsekedwa ndikuchepetsa kuchuluka kwa ma AO awiri. Oyenera ntchito kutentha mkulu processing, PP, BOPP Kakhungu chuma, PC mandala zobwezerezedwanso zakuthupi, styrene polima, PPR chitoliro zakuthupi, TPU, zomatira, etc. |
Kuti ipereke zowonjezera polima pazinthu zina, kampani yakhazikitsa zinthu zomwe zili pansipa: PA polymerization & zosintha zowonjezera, zowonjezera zowonjezera za PU, ma polymerization a PVC & zowonjezera zowonjezera, zowonjezera PC, zowonjezera za TPU elastomer, zotsika zazing'ono za VOC zamagalimoto zowonjezera zowonjezera, zokutira zokutira, zowonjezera zodzola, API ndi zinthu zina zamankhwala monga zeolite ndi zina.
Mwalandilidwa kuti mutilankhule nafe pakafunso!
