High ceev tshuaj urethane ua npuas ncauj lub rooj tsavxwm kuj hu ua HDU lub rooj tsavxwm yog siv rau tes-carved kos npe nrog rau CNC-machining. Siab ceev Urethane muaj nyob rau hauv ntau yam ntawm daim ntawv loj, thicknesses, thiab ceev. Nws tuaj yeem txiav los yog sib koom ua ke rau hauv ntau yam duab rau qhov kawg machining lossis shaping.

Ntawm no, polyurethane siv rau dab tsi?

Polyurethane ua npuas ncauj yog dav siv nyob rau hauv siab resiliency saj zawg zog ua npuas ncauj zaum, nruj npuas rwb thaiv tsev panels, microcellular ua npuas ncauj seals thiab gaskets, ruaj elastomeric log thiab log tsheb, tsheb ncua kev kawm ntawv bushings, hluav taws xob potting tebchaw, seals, gaskets, ntaub pua plag underlay, thiab tawv yas qhov chaw (xws li rau

Kuj Paub, dab tsi yog qhov tsis zoo ntawm polyurethane? Cov neeg uas raug tshaj tawm polyurethane ntsib teeb meem kev noj qab haus huv suav nrog kev ua xua, ua pob liab liab, ua pa nyuaj, tsis nco qab thiab txawm qhov muag tsis pom. Yog tias koj ob lub qhov muag lossis tawv nqaij los ntawm kev sib cuag nrog polyurethane ua npuas ncauj, ntxuav thiab yaug kom huv si kom tsis txhob muaj teeb meem kev noj qab haus huv.

Ib yam li ntawd, dab tsi yog ua los ntawm polyurethane?

6 Feem ntau siv Polyurethane

  • Rooj tog, txaj, thiab rooj zaum. Polyurethane feem ntau molded ua npuas ncauj uas tuaj yeem ua haujlwm rau ntau yam kev siv rau tib neeg kev nplij siab.
  • Thermal rwb thaiv tsev. Tsawg-density nruj polyurethane muaj ntau yam kev siv-ib qho tseem ceeb tshaj plaws yog nws daim ntawv thov thermal rwb thaiv tsev.
  • Elastomers.
  • Khaub ncaws.
  • Cov hlua.
  • Txheej txheej.

Polyurethane rwb thaiv tsev yog dab tsi?

Polyurethane yog tsim los ntawm kev sib tov ib qho isocyanate, xws li methylene diphenyl diisocyanate (MDI) nrog cov khoom siv polyol. Cov khoom no yog sib xyaw ua ke los ua ib qho tawv, cellular foam matrix. Cov khoom uas tau tshwm sim yog ib qho hnyav heev polymer nrog superior rwb thaiv tsev khoom.
