Xaiv qhov raugPolyether polyol rau tshuaj tsuag polyurethane ua npuas ncauj (SPF)Nws yog ib qho tseem ceeb rau kev ua tiav qhov kev ua tau zoo ntawm kev rwb thaiv tsev thiab kev siv nyiaj txiag.
Yam tseem ceeb uas yuav tau xav txog
Thaum xaiv polyether polyols, xav txog:
1. Kev ua haujlwm
Kev ua haujlwm siab dua ua rau muaj zog crosslinking, zoo tagnrho raukaw- cell rigid foam rwb thaiv tsev.
2. Reactivity
Balanced reactivity kom zoo foaming thiab curing nyob rau hauvkev siv tshuaj tsuag.
3. Viscosity
Muaj feem xyuam rau kev ua, sib tov, thiab tshuaj tsuag kev ua haujlwm.
4. Compatibility nrog dej -Blown Systems
Qhov tseem ceeb rau kev ua tiav cov qauv ua npuas ruaj khov tsis muaj qhov tsis xws luag.
Sib piv Polyols nrog cov ntawv thov
Rwb thaiv tsev→ siab -qhov ceev kaw- cell foam
Phab ntsa rwb thaiv tsev→ balanced kev ua tau zoo systems
Sab hauv rwb thaiv tsev→ qhib - cell foam
Siv txoj caipolyether polyol formulationkom zoo zog efficiency thiab durability.
Kev Lag Luam Kev Lag Luam thiab Lub Sijhawm
Kev thov thoob ntiaj teb rau:
Txau npuas rwb thaiv tsev tshuab
