Polyester Polyols siv rau Casting Polyurethane, polyester polyols casting polyurethane series yog ib hom polyurethane prepolymer uas yog tsim los ntawm kev siv polyester polyols.
Luv luv
Nyob rau hauv daim teb ntawm casting polyurethane elastomers, polyester polyols casting polyurethane series yog dav siv.
Nws feem ntau yog siv nyob rau hauv siab hardness polyurethane sieve daim hlau, casters, cots, daim hlau thiab tuav, thiab molded potting khoom.
Kev siv cov polyester polyols hauv cam khwb cia polyurethanes yog ib qho chaw siv ntau.
Cam khwb cia polyurethane yog cov txheej txheem uas cov khoom siv ua kua polyurethane yog nchuav rau hauv pwm thiab reacts thiab solidifies los tsim cov khoom lag luam.
Polyester polyols yog qhov yooj yim, lub zog thiab kev sib txuas ntawm cov cam khwb cia polyurethane.
Tau txais txiaj ntsig
polyurethane casting khoom muaj cov txiaj ntsig hauv qab no:
1. Polyester polyol muaj qhov tsim nyog fluidity thiab sau cov khoom, uas tso cai rau cov kua polyurethane kom puv cov khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob.
2. Lub hardness, lub zog, toughness thiab lwm yam kev thov yuav ua tau los ntawm kev kho cov qty ntawm polyester polyol.
3. zoo hnav thiab tshuaj tiv thaiv
4. Tsawg linear shrinkage thiab ruaj khov qhov hloov pauv, tso cai rau nws cov khoom tiav los tswj cov duab thiab qhov ntev.
5. Hom thiab qhov sib piv ntawm polyester polyols tuaj yeem hloov kho raws li cov kev xav tau tshwj xeeb kom tau txais cov khoom tshwj xeeb thiab cov yam ntxwv, xws li hardness range, flowability thiab curing lub sij hawm.
