TDI 80/20 (Toluene Diisocyanate 80/20) yog cov khoom siv raw tshuaj tseem ceeb, feem ntau yog siv nyob rau hauv synthesis cov ntaub ntawv. Raws li cov kev tshawb fawb txog kev tshawb fawb thiab kev tshawb xyuas kev lag luam, nws cov khoom siv tshwj xeeb thiab cov khoom lag luam suav nrog cov hauv qab no:
1. POLYURETHANE muag ua npuas ncauj
TDI 80/20 yog cov khoom siv raw rau kev npaj ntawm polyurethane mos ua npuas. Hom kev ua npuas no muaj cov kev nqus zoo, nqus nqus thiab lub rwb thaiv tsev tshav kub, thiab yog siv dav hauv:
- Kev lag luam kev lag luam: xws li Sofas, daim txaj txaj, Cushions thiab lwm cov ntaub ntawv puv.
- Kev lag luam Automotive: Siv rau Cushioning txheej ntawm cov rooj zaum, cov hau kev, thiab sab hauv los txhim kho kev nplij siab thiab kev nyab xeeb.
- Kev tsim kho cov teb: raws li suab rwb thaiv tsev thiab thermal rwb thaiv tsev cov ntaub ntawv, siv hauv phab ntsa lossis cov roj av pastration txheej.
2. Polyurethane Elastomers
Los ntawm kev kho cov qauv thiab cov txheej txheem, TDI 80/20 tuaj yeem suav ua ke elastomers rau cov khoom hauv qab no:
- Chaw nyob: xws li cov ntsaws ruaj ruaj, kev nqus kom tsis zoo, kev nqus, conveyor siv tawv, thiab lwm yam coj tsis kam thiab roj tsis kam.
- Kev tsim khau: Cov kis las khau midsoles, insoles, thiab lwm yam, muab teeb ci thiab muaj peev xwm.
- Cov cuab yeej kho mob: substrates rau qee cov tib neeg kho mob thiab cov khoom siv khoom noj khoom.
3. Cov xim tha xim thiab txheej
TDI 80/20 raws li tus neeg sawv cev hla kev tuaj yeem txhim kho cov nplaum thiab huab cua tiv thaiv ntawm txheej txheej. Daim Ntawv Thov Kev Ua Ntawv Muaj xws li:
- ntoo txheej txheem ntoo: high-hardness tiv thaiv txheej ntawm cov chaw ntawm rooj tog thiab pem teb.
- Lub cev tsheb: Tsheb lub tsheb primer lossis topcoat los txhim kho corrosion tsis kam.
- Muaj cov txheej txheem corrosion: siv rau kev tiv thaiv xeb ntawm cov hlau hluav taws xws li cov kav nkoj thiab tso tsheb hlau luam.
4. Cov ntawv nplaum thiab cov xov xwm
Lub luag haujlwm ntawm TDI 80/20 hauv thaj chaw cov nplaum nplaum yog qhov yooj yim tshwm sim hauv:
- Composite Board Kev Ua Haujlwm: xws li kev sib txuas ntawm cov khoom siv hluav taws xob sab hauv thiab architectural zoo nkauj panels.
- Khau lo: Kev sib tham ntawm khau ncaws pob thiab tawv khau, muaj zog siab thiab dej tsis kam.
- Hluav Taws Xob Ntim Ntim: Sealing thiab kho ntawm cov hluav taws xob hauv hluav taws xob.
5. Ncua daim ntawv thov ntawm hloov kho TDI
Ntshiab TDI 80/20 muaj qhov tsis zoo xws li muaj kev tsis sib haum siab thiab cov haujlwm tsis muaj nuj nqi. Kev hloov kho tshuaj lom neeg (xws li cov tshuaj tiv thaiv nrog Allophangate) tuaj yeem txhim kho kev kawm thiab nthuav dav rau:
- Kev ua haujlwm siab ua npuas dej: Cov siab kub tiv taus thiab nplaim taws retardant npaus, siv hauv aerospace lossis tsheb tshwj xeeb.
- Tshwj xeeb elastomers: xws li hydrolysis-cov tshuaj tiv thaiv hydrolysis-tiv taus thiab UV-resistant sab nraud cov khoom siv.
- Ib puag ncig tus phooj ywg cov txheej txheem: qis voc txheej txheej uas tau ntsib cov qauv yas.
Kev Lag Luam Kev Ua Lag Luam thiab Cov Qauv Nruab Nrab
Kuv lub teb chaws tdi 80/20 ntau lawm muaj kev nce qib txij li cov phiaj xwm kev tsim khoom "yim tsib xyoos, tab sis nws tseem yuav tau nthuav nws cov ntawv thov los ntawm kev txhim kho kev siv thev naus laus zis los ntawm kev txhim kho thev naus laus zis. Kev tshawb fawb thiab kev txhim kho ntawm kev hloov kho TDI tau txiav txim siab yog tus yuam sij rau kev ua lag luam yav tom ntej, tshwj xeeb yog cov khoom lag luam high-kawg.
