Lub luag haujlwm ntawm kev ntxiv MOCA rau Polyurethane Prepolymer?
1. Dab tsi yog moca
MOCA yog ib feem ntau siv ntxiv nrog cov qauv tshuaj lom neeg ntawm isocyanate thiab isocyanate derivatives, uas muaj zoo reactivity thiab volatility. MOCA tuaj yeem hnov cov qauv hluavtaws los ua cov qauv hluavtaws tsim 3D-seem-seem, txhim kho lub zog, hardness thiab hnav tsis kam ntawm cov khoom.
2. Lub luag haujlwm ntawm kev ntxiv MOCA rau Polyurethane Prepolymer?
Raws li ib qho tseem ceeb tso cov khoom siv, polyurethane expolymer tau siv dav hauv kev npaj ntawm ntau cov ntaub ntawv polymer thiab cov khoom lag luam. Txawm li cas los xij, Polyurethane Prepolymer nws tus kheej muaj siab viscosity thiab fluolity tsis zoo, uas tsis yog qhov txaus ua rau kev ua thiab moulding. Yog li ntawd, qee qhov ntxiv ntxiv yuav tsum tau ntxiv los txhim kho nws cov txheej txheem thiab kev ruaj khov.
Raws li ib feem ntau siv additive, moca tuaj yeem ua txoj haujlwm hauv qab no:
1. Txhim kho viscosity thiab Fellity: Moca tuaj yeem hnov mob nrog polyurethane expolymer los tsim kom zoo dua qub, txo nws lub viscosity, thiab yog ua kom zoo rau kev ua thiab moulding.
2. Hloov kho hardness thiab Elastic Modulus: Cov qauv kev xav tau tuaj yeem tsim cov qauv 3D thiab yog qhov tsim nyog rau kev npaj ntau cov polyurethane khoom nrog lub hardness thiab lub zog yuav tsum tau ua.
3. Txhim kho cov hnav tsis kam: MOCA cov tshuaj tiv thaiv tuaj yeem tsim cov txheej txheej saum npoo av, txhim kho cov hnav tsis kam thiab cov kev pabcuam ntawm polyurethane cov khoom lag luam.
Cov ntaub ntawv thov ntxiv rau kev ntxiv MOCA rau Polyurethane Prepolymer?
Ntxiv MOCA rau Polyurethane Prepolymer yog ib txoj hauv kev los txhim kho kev ua haujlwm thiab cov khoom lag luam, thiab tau siv dav hauv ntau thaj teb.
1. Lub tsheb txheej: polyurethane txheej yog cov khoom siv tseem ceeb, uas tau siv dav nyob rau hauv cov txheej txheej ntawm ntau yam tsheb xws li tsheb, thiab dav hlau. Ntxiv MOCA tuaj yeem txhim kho lub hardness thiab hnav tsis kam ntawm polyurethane txheej, thiab txhim kho nws cov huab cua tsis kam thiab tshuaj lom neeg.
2. Luam tawm number case: POLYURETHANE POLLECEASE ZOO, huab cua tiv thaiv thiab tshuaj lom neeg, thiab yog cov khoom tseem ceeb luam ntawv. Ntxiv MOCA tuaj yeem txhim kho fluidity thiab ruaj khov ntawm polyurethane number case polyurethane, thiab txhim kho nws cov ntawv tshaj tawm thiab zoo.
Tib qho khoom siv: Polyurethane yog ib qho tseem ceeb tib yam khoom nrog zoo elasticity, hnav tsis kam thiab roj tsis kam thiab roj ua hauj. Ntxiv MOCA tuaj yeem hloov kho lub hardness thiab Elisastic Modulus ntawm Polyurethane, nce lub zog, thiab yog qhov tsim nyog rau kev npaj ntau cov ntaub ntawv.
