Product Description
Polyester Based Polyurethane Prepolymer yog siv los ua cov ntaub ntawv ua ntej rau ntau yam kev siv xws li molding compounds, sealants thiab adhesives, coatings, thiab lwm yam khoom tshwj xeeb.
Cov khoom siv tau zoo heev rau kev puas tsuaj, cov roj ua haujlwm zoo, thiab cov cuab yeej zoo txhua yam. Cov khoom tuaj yeem ua rau muaj yeeb yuj los ntawm kev ntxiv xim xim rau hauv PU prepolymer.
Lub hardness ntawm BQ3243 tuaj yeem hloov kho los ntawm MOCA thiab TMP.
Vim tias qhov sib ntxiv ntawm TMP, cov khoom siv kho tshuab tau zoo heev. Cov qauv dawb tuaj yeem muab rau koj qhov kev xeem.
Polyester Raws li Polyurethane Prepolymer lag luam yog segmented rau hauv siab viscosity thiab tsawg viscosity hom. High viscosity Polyester Raws li Polyurethane Prepolymer feem ntau yog siv rau cov ntawv thov kom muaj zog thiab muaj zog, thaum tsis tshua muaj viscosity Polyester Based Polyurethane Prepolymer pab txhawb kev khiav zoo thiab yooj yim ntawm kev ua. Qhov kev sib txawv no cuam tshuam rau lawv cov kev siv hauv cov ntawv thov tshwj xeeb, kho cov yam ntxwv ua haujlwm kom tau raws li kev lag luam xav tau.
Nyob rau hauv cov nqe lus ntawm kev siv, kev ua lag luam ua hauj lwm rau ntau yam sectors xws li automotive, mechanical, electronics, khau thiab kev ua si, kev kho mob industries, thiab lwm yam. Txhua lub lag luam siv cov khoom siv prepolymers rau lawv cov khoom tshwj xeeb, xws li yoog raws, toughness, thiab tsis kam hnav, txhim kho cov khoom lag luam thiab kev ua haujlwm ntev ntawm ntau hom kev siv.

Txheej txheem txheej txheem
Tus neeg sawv cev curing yog yaj thiab tov nrog prepolymer tib lub sijhawm, qhov sib xyaw kub yog tswj ntawm 75 ~ 85 degree, pwm kub yog 120 degree, thiab vulcanization yog 16h hauv qab 110 degree.
Cia
1. Lub prepolymer yuav tsum tau muab cia rau hauv qhov chaw qis thiab qhuav, thiab tsis txhob ya raws thiab dej vapor thaum siv.
2. Lub prepolymer tom qab qhib yuav tsum tau siv kom sai li sai tau. Yog tias nws tsis siv tas li, nws yog qhov zoo tshaj kom kaw nws nrog nitrogen.
3. Yog tias koj xav ntxiv cov xim pleev xim lossis lwm yam khoom siv, thov khaws cov dej ntawm cov khoom ntxiv hauv qab no 0.1%, thiab xav txog qhov sib xyaw ntawm cov khoom ntxiv.
