PTMEG thiab TDI polyurethane prepolymeryog ib hom polyurethane prepolymer uas yog tsim los ntawm cov tshuaj tiv thaiv ntawm polytetramethylene ether glycol (PTMEG) thiab toluene diisocyanate (TDI). Nws yog nquag siv nyob rau hauv ntau yam sectors, rau nws tshwj xeeb zoo thiab adaptability.
PTMEG TDI Polyurethane Prepolymer nthuav tawm lub zog tshwj xeeb, elasticity, thiab ua haujlwm zoo.
Nws tuaj yeem tiv taus cov kev ntxhov siab thiab kev nyuaj siab yam tsis muaj kev deformation mus tas li, ua rau nws tsim nyog rau cov ntawv thov uas yuav tsum tau ua kom ntev.
Qhov zoo
PTMEG TDI series polyurethane prepolymer no muaj kev tiv thaiv zoo rau ntau yam tshuaj, suav nrog cov kuab tshuaj, roj, thiab roj.
PTMEG TDI Polyurethane Prepolymer tuaj yeem tsim rau hom hardness, los ntawm muag muag thiab hloov tau mus rau nruj. Tom qab ntawd siv dav hauv ntau daim ntawv thov uas xav tau ntau theem ntawm hardness thiab elasticity.
Thiab PTMEG series Polyurethane Prepolymer muaj kev tiv thaiv zoo rau UV hluav taws xob, noo noo, thiab kub.

Kev ua haujlwm
Tom qab lub tshuab nqus tsev degassing ntawm 80-85 degree, polyester thiab TDI polyurethane prepolymer yog tov nrog melted MOCA.
Qhov sib tov yog tom qab ntawd raug degassing, casting, thiab vulcanization molding.
Cov txheej txheem no muaj feem xyuam rau ob qho tib si kev ua haujlwm ntawm phau ntawv thiab cov tshuab casting.
tuav
1. Tsis txhob kov ncaj qha rau ntawm daim tawv nqaij thiab qhov muag.
2. Ceev faj kom tsis txhob nqus pa los yog huab cua.
3. Khaws kom deb ntawm cov nplaim taws thiab tsis txhob haus luam yeeb.
4. Siv cov kev ntsuas los tiv thaiv kev tsim ntawm electrostatic nqi.
Thov nco ntsoov tias cov no yog cov txheej txheem kev nyab xeeb dav dav thiab nws yog ib qho tseem ceeb uas yuav tsum tau xa mus rau cov lus qhia txog kev nyab xeeb tshwj xeeb uas muab los ntawm cov chaw tsim khoom lag luam lossis nrog tus kws tshaj lij kev nyab xeeb kom paub tseeb thiab ntxaws ntxaws.
