Dab tsi yog cov tseem ceeb ntawm TDI 80/20?
Ib qho ntawm cov ntsiab lus tseem ceeb tshaj plaws ntawm TDI 80/20 yog nws cov kev ua kom zoo. Nws reacts sai li sai nrog polyols ntawm cov kub tsawg, uas shortens ntau lawm cycles thiab nce kev ua tau zoo. Cov versatility ntawm cov khoom no tseem sawv tawm. Nws tuaj yeem ua ke nrog ob lub polyether thiab polyester polyols, tso cai rau cov tuam txhab kom zoo nyob ntawm seb lawv puas xav tau kev hloov pauv, tsis muaj kev cuam tshuam, lossis kav ntev.
Ib qho ntxiv, cov khoom siv polyurethane raws li TDI 80/20 muaj kev ua haujlwm zoo heev. Cov khoom lag luam pom zoo qhia kom zoo tensile muaj zog, resilison, thiab nws tsis kam ua rau ib puag ncig ua haujlwm nyuaj. Piv nrog rau lwm cov ntaub ntawv raw, TDI 80/20 tseem ua rau muaj cov yam ntxwv ua tau zoo, ua rau nws yooj yim dua los daws cov ntawv thov txuas ntxiv.
Dab tsi yog cov ntawv thov tseem ceeb ntawm TDI 80/20?
1. Ua Npuas Ncauj
Kev siv ntau tshaj plaws ntawm tdi 80/20 yog nyob rau hauv yooj yim polyurethane ua npuas, uas yog qhov txhia chaw hauv lub neej niaj hnub no. Nyob rau hauv cov rooj tog kev lag luam, nws yog tus caj qaum ntawm siab {3} RoFience foams siv hauv Sofas, thiab Cushions, muab kev nplij siab thiab txhawb nqa. Nyob rau hauv lub tsheb saib tsheb, nws mus rau hauv lub rooj zaum, headrests, thiab sab hauv lub Cheebtsam, ua kom muaj kev nyab xeeb thiab ergonomic tsim. Txawm nyob hauv ntim, ua npuas ncauj raws TDI 80/20 muab lub teeb ci ntsa iab uas tiv thaiv cov khoom siv hluav taws xob thiab cov twj siv thaum thauj.
2. Cov txheej txheem thiab cov nplaum
TDI 80/20 kuj tseem yog cov khoom tseem ceeb hauv ob -} sib xyaw polyurethane txheej thiab cov nplaum. Cov txheej txheej no sawv tawm rau lawv cov ci, durability, thiab tawm tsam cov kuab tshuaj thiab huab cua. Raws li qhov tshwm sim, lawv tau siv dav hauv cov ntoo ua tiav, kev tiv thaiv hlau, pem teb, thiab txawm tias cov khoom siv muaj khoom siv. Cov nplaum muaj txiaj ntsig raws li TDI 80/20 yog muaj nuj nqis hauv khau kev lag luam, tsim kho thiab dav dav vim tias lawv tau muab kev sib raug zoo thiab ntev}- kav ntev.
3. Elastomers
Thaum tsim cov elastomers, TDI 80/20 muab cov khoom uas zoo hnav tsis kam thiab rhuav lub zog. Cov ntaub ntawv no tau siv rau hauv cov cav tsuas, cov zaub mov, cov log, thiab qhov chaw damping, uas depabiling yog qhov tseem ceeb. Lub peev xwm los tswj kev ruaj khov nyob rau hauv kev ntxhov siab tas mus li ua rau lawv tsis tseem ceeb hauv kev hnyav- cov dej num muaj chaw.
4. Lwj thiab encapsulation
Lwm qhov tseem ceeb teb yog cov ntxaij vab tshaus thiab potting sib txuas. Hauv cov khoom siv hluav taws xob thiab kev tsim kho, TDI 80/20 pab tsim polyurethane cov ntaub ntawv uas tiv taus noo noo, cua hloov pauv, thiab kev ntxhov siab thiab txhua yam kev ntxhov siab. Qhov no ua kom ntev ntev -} kev tiv thaiv ntawm cov khoom siv rhiab thiab txhim khu kev qha ntawv sau npe hauv cov khoom xav tau.
Vim tias nws cov versatility thiab kev lag luam zoo, tdi 80/20 tseem yog ib lub tsev tseem ceeb tshaj plaws hauv ntiaj teb Polyurethane tus nqi saw. Raws li kev lag luam xws li cov rooj tog, kev tsim kho, thiab ntim txuas ntxiv kom loj hlob, qhov kev thov ua npuas zoo thiab cov txheej txheem yuav tsuas yog nce. Nyob rau tib lub sijhawm, cov chaw tshiab zoo li cov khoom lag luam ntsuab, zog - Cov rooj tog khoom lag luam, thiab lub teeb ci ua haujlwm rau tdi- based cov khoom.
