Ua npuas ncauj yas yog ib qho ntawm cov khoom siv hluavtaws tseem ceeb ntawm polyurethane cov khoom siv hluavtaws, yog li nws cov kev tsis sib haum xeeb yog qhov me me, thiab nws lub zog tshwj xeeb yog qhov siab. Raws li cov ntaub ntawv sib txawv thiab cov mis sib txawv, nws tuaj yeem ua rau hauv cov muag muag, semi-nruj thiab nruj polyurethane ua npuas dej yas thiab lwm yam ..
PU ua npuas ncauj yog siv dav, yuav luag infiltrating rau txhua cov haujlwm ntawm kev lag luam hauv tebchaws, tshwj xeeb tshaj yog, kev tsim kho, rwb thaiv tsev thiab ntau lwm cov kev siv.
Polyurethane ua npuas ncauj yog tsuas yog thov rau cov rooj tog, cov khoom lag luam hauv tsev, xws li rooj zaum thiab rooj tog, kab txaj muag thiab hauv ncoo.
Hauv kev tsim khoom tiag tiag thiab siv, cov khoom lag luam feem ntau yuav tsum muaj cov kev xav tau ntawm kev daj daj tsis taus thiab nplaim taws retardant. Lub tuam txhab muab ntau yam ntxiv tuaj yeem pab tau zoo txhim kho cov khoom lag luam.
Lub tuam txhab tuaj yeem muab rau hauv qab pu ua npuas ncauj ntxiv:
| Kev sib faib | Khoom | Cas | Khoom Yam | Daim ntawv thov |
| UV ABSORBER | Yihoo UV1 | Dav siv nyob rau hauv PU, Adhesive, Ua Npuas Ncauj thiab Lwm Cov Khoom Siv. | ||
| Yihoo UV571 | Tinuvin 571 | Widely used in thermoplastic PUR coating and integral foam plastics, hard plasticized polychloride,PVB,PMMA,PVDC,EVOH, EVA, high temperature curing unsaturated polyester and PA, PET,PUR and PP fiber spinning AIDS. | ||
| Yihoo UV B75 | Tinuvin b75 | Compound UV nqus, tsuas yog siv rau ntawm PU, cov nplaum lossis suab paj nruag, xws li tarpaulin, tawv nqaij thiab hluavtaws tawv. | ||
| Tshuaj tua kab mob antioxidant | Yihoo An333 | JP333E | Cov tshuaj phenol-free antioxidant, siv raws li cov tshav kub siv hluav taws xob hauv PVC, txhim kho cov xim thiab pob tshab ntawm PVC cov khoom lag luam. Nws kuj tseem siv tau rau hauv cov roj hmab thiab pu cov khoom siv los txhim kho kom muaj kev tiv thaiv kev tiv thaiv. | |
| Yihoo An340 | Phenol Free Antioxidant, tuaj yeem siv dav siv hauv PVC, ABS, SBR, CR ETCE. | |||
| Nplaim taws retardant | Yihoo fr950 | / | Chlorinated phosphate eser Eser retardant, tshwj xeeb tshaj yog tsim nyog rau nplaim retardant pu ua npuas ncauj. Nws tuaj yeem pab kom dhau California 117 tus qauv, FMVSS, FMVSS, FMVSS, FMVSS ntawm tsheb tavxij, Askiv tus qauv 5852 tsaj ntsuas tus qauv. Fr950 yog qhov zoo tshaj plaws nplaim retardant los hloov tdcpp (carcinogenicity) thiab v-6 (muaj carcinogen t corep). |
Txhawm rau muab cov ntawv thov tshwj xeeb ntxiv, lub tuam txhab tau tsim cov khoom sib ntxiv hauv qab no, siv ua npuas ncauj ntxiv, pum polymerization, pu tsev poline, pu ua npuas ncauj ntxiv, pu khoom ua npuas ncauj ntxiv, pu tsev polrification, cov tshuaj txhuam ntxiv, tshuaj pleev ib ce ntxiv, tshuaj pleev ib ce thiab lwm yam tshuaj cov khoom lag luam zoo li Zeolite thiab lwm yam
Koj ib txwm zoo siab tos txais hu rau peb txog cov lus nug!
