Inov Blend Ua Npuas Ncauj Polyether Polyol rau Lub tub yees / Lub Freezer / Cov Khoom Siv Hluav Taws Xob
Doncool 102 HCFC-141B puag muab polyols
Taw qhia
DonCool 102 yog sib xyaw polyols, siv HCFC-141B ua tus neeg sawv cev tshuab, uas yog kev hloov pauv ntawm CFC-11 hauv kev lag luam polyurethane, nws siv rau cov tub yees, icebox thiab lwm yam khoom siv thermal rwb thaiv tsev, cov yam ntxwv yog raws li nram no,
1. Kev muaj peev xwm txaus zoo heev, ua npuas ncauj ntom ntom yam ntxwv coj ua ke, qis thermal conductivity
2. Zoo heev uas tsis tshua muaj qhov ntev stability thiab cohesiveness
3. Demould lub sij hawm 6 ~ 8 feeb
