Nta ntawm PU sab nrauv phab ntsa vaj huam sib luag:
1. Dav kub ntau yam
Kev siv kub ntawm cov khoom siv tseem ceeb yog -196 degree ~ 130 degree, thiab qhov kub ntawm qhov tam sim no nce mus txog 200 degree. Thaum siv hauv qhov kub thiab txias lossis ib puag ncig qis, lub shrinkage yog me me, thiab nws tsis nkig. Nws yog ib qho zoo tshaj plaws thermal rwb thaiv tsev khoom rau cryogenic (txias cia) engineering.
2. Tsawg thermal conductivity
Lub thermal conductivity ntawm composite PU vaj huam sib luag yog me me, thiab thermal rwb thaiv tsev kev ua tau zoo.
3. Tsis muaj tshuaj lom thiab tsis qab
Cov khoom tseem ceeb ntawm PU vaj huam sib luag tsis siv Freon ua tus neeg sawv cev foaming. Nws yog non-toxic thiab tasteless thaum hlawv, thiab cov roj volatilized tsis muaj teeb meem rau tib neeg ib puag ncig. Nws ua tau raws li lub teb chaws kev tiv thaiv ib puag ncig thiab yog hom tshiab ntawm cov khoom siv ntsuab.
4. Waterproof thiab moistureproof
Cov khoom tseem ceeb ntawm PU vaj huam sib luag yog cov organic polymer ua npuas dej nrog cov qauv kaw, uas muaj cov dej nqus dej zoo thiab dej vapor permeability tsis kam.
