Polyurethane yog dab tsi? - Kev Paub Koj yuav tsum paub txog Polyurethane
Dab tsi's tus common npe ntawm polyurethane?
PU--npe npe
TPU - thermoplastic polyurethane
CPU-casting polyurethane
PPU - polyurethane ua npuas ncauj
Dab tsiQhov zoo ntawm Polyurethane yog dab tsi?
-Muaj zoo mechanical nco,
- ruaj khov,
- Muaj peev xwm siv tau ntawm qhov siab txog li 1000 atmospheres,
- Daim ntawv thov kub ntau yog -50 C txog +110 C,
- Zoo heev UV tiv thaiv,
- Cov txiaj ntsig kev lag luam. Txo tus nqi ntawm kev hloov cov khoom,
- Kev tiv thaiv zoo rau ntau yam tshuaj:
Saturated thiab aliphatic daws,
10% acid thiab alkali tov,
cav roj,
roj thiab roj,
oxidizing tus neeg sawv cev,
dej hiav txwv.
Thaum twg txwv tsis pub siv polyurethane?
- Ua haujlwm kub siab tshaj +110 degree,
- ua haujlwm nyob rau hauv kub kub nrog high humidity,
- ua haujlwm hauv dej ntawm qhov kub siab tshaj +80 C,
- Ua haujlwm hauv qee qhov chaw corrosive chemical.
Kev sib tw zoo ntawm polyurethane ua cov khoom sib piv nrog roj hmab:
-Resistant rau txiav thiab kua muag,
- Roj resistant,
- Ntau yam hardness,
-Resistant rau ozone.
Dab tsi's tnws kev sib tw zoo ntawm polyurethaneVSyas?
- Tsis muaj kev cuam tshuam,
- ruaj khov,
- Elastic nco
Dab tsi's tnws kev sib tw zoo ntawm polyurethaneVS hlau?
- Xya lub sij hawm sib zog dua hlau,
- High hnav tsis kam,
- Kev ua haujlwm tsis muaj suab nrov,
- Impact resistance,
- Tsis muaj corrosion.
Dab tsi yog qhov tsis zoo ntawm polyurethane?
-Txoj kev puas tsuaj los ntawm kev sib cuag nrog cov ntxhiab hydrocarbons, qee cov kua qaub, turpentine thiab cov tshuaj chlorine-muaj cov tshuaj;
-Vim cov khaub ncaws tsis breathable thaum lub sij hawm tsim khoom, nws siv yog txwv;
-Thaum qhov kub thiab txias, cov khoom ua nkig;
- Cov kev xav tau pov tseg siab;
-Qhov nyuaj ntawm kev rov ua dua tshiab.
Polyurethane yog cov khoom siv ntau heev. Ntau yam khoom yog tsim los ntawm nws.
Piv txwv li, nyob rau hauv cov tshuaj, nws yog siv los tsim cov hnab looj tes, uas yog ruaj, du, tsis tshua muaj nqi thiab ib puag ncig tus phooj ywg.
Lub tsheb log tsheb kuj ua los ntawm cov khoom no. Tsis tsuas yog lawv kav ntev dua cov roj hmab, lawv kuj tsis muaj cov cim.
Kuj tsim nyog hais txog cov khoom siv polyurethane xws li O-rings, bushings thiab cuffs.
Cov khoom no yog siv los ua cov khoom siv insulating.
Cov ntaub ntawv thov kuj tseem siv rau hauv kev tsim cov txaj pw hauv kev lag luam rooj tog.
Yog tias koj yuav polyurethane rollers, koj tuaj yeem paub tseeb tias lawv yuav kav ntev. Ntau lub khob nqus dej, cov ntsiab lus qhia, cov ntaub qhwv, cov ntaub qhwv, rub, cov ntawv raj thiab lwm yam khoom kuj tau tsim los ntawm cov khoom siv no.
