Pulasitiki ya thovu ndi imodzi mwazinthu zazikulu kwambiri zopangidwa ndi polyurethane, zomwe zimakhala ndi porosity, chifukwa chake kuchuluka kwake kumakhala kochepa, ndipo mphamvu yake ndiyapamwamba. Malinga ndi zipangizo zosiyanasiyana zopangira ndi chilinganizo, zikhoza kupangidwa kukhala zofewa, theka-okhwima ndi okhwima polyurethane thovu pulasitiki etc.
Chithovu cha PU chimagwiritsidwa ntchito kwambiri, pafupifupi kulowerera m'magulu onse azachuma, makamaka mipando, zofunda, mayendedwe, kuzizira, zomangamanga, kutchinjiriza ndi ntchito zina zambiri.
Polyurethane thovu imagwiritsidwa ntchito makamaka ku mipando, zofunda ndi zinthu zapakhomo, monga masofa ndi mipando, mabasiketi obwerera kumbuyo, matiresi ndi mapilo.
Pakapangidwe kake ndi kagwiritsidwe kake, zinthuzi nthawi zambiri zimafunikira zofunikira kwambiri zakusakanikirana ndi chikasu ndi lawi lamoto. Kampaniyi imapereka zowonjezera zowonjezera zomwe zingathandize kukonza magwiridwe antchito.
Kampaniyo imatha kupereka zowonjezera zowonjezera za PU:
| KUGawanika | PRODUCT | CAS | MTUNDU WA COUNTER | NTCHITO |
| UV WABWINO | YIHOO UV1 | Chimagwiritsidwa ntchito PU, zomatira, thovu ndi zipangizo zina. | ||
| YIHOO UV571 | TINUVIN 571 | Amagwiritsidwa ntchito kwambiri popaka ma thermoplastic PUR komanso mapulasitiki oyambira, polychloride yolimba, PVB, PMMA, PVDC, EVOH, EVA, kutentha kwakukulu kuchiritsa polyester osaturated ndi PA, PET, PUR ndi PP fiber yoluka Edzi. | ||
| YIHOO UV B75 | TINUVIN B75 | Makina opanga UV, omwe amagwiritsidwa ntchito kwambiri pa PU, zomatira kapena zokutira za PUR, monga zopangira lona, nsalu zoyambira ndi zikopa zopangira. | ||
| WOSANGALATSA | YIHOO AN333 | 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 AN340 | Phenol wopanda antioxidant, atha kugwiritsidwa ntchito kwambiri mu PVC, ABS, SBR, CR ndi zina. | |||
| MPHAMVU YOPHUNZITSA | YIHOO FR950 | / | Mankhwala phosphate Ester lawi wamtundu uliwonse, makamaka oyenera lawi wamtundu uliwonse PU thovu. Iwo akhoza kumathandiza pochitika California 117 muyezo, FMVSS302 muyezo wa chinkhupule galimoto, British muyezo 5852 Crib 5 ndi zina lawi retardant mfundo mayeso. FR950 ndiye choyimira chamoto choyenera m'malo mwa TDCPP (carcinogenicity) ndi V-6 (yokhala ndi khansa ya TCEP). |
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!
