Polyol Blends siv rau kev txuas txuas ntxiv

Polyol blends siv rau kev tsim cov vaj huam sib luag txuas ntxiv yog lub tshuab hluav taws xob hydrocarbon, muaj cov polyols thiab txhua yam tsim nyog ntxiv tshwj tsis yog tshuab tshuab hydrocarbon (pentane yog nyiam). Tom qab sib tov nrog tus neeg sawv cev tshuab, nws tuaj yeem hnov mob nrog polymeric MDI kom tau nruj polyurethane ua npuas ncauj.

Lus Cim: Cov npuas dej yog tsim los ntawm kev sib xyaw ntawm tes hauv kab rov tav pwm (pwm loj: 300 * 300 * 100mm), pwm kub: 40 degree. Cov khoom ua npuas ncauj yuav txawv yog tias foaming mob txawv.

Peb kuj muaj lwm cov ntaub ntawv PU ua npuas ncauj raw khoom rau lub vaj huam sib luag sandwich kom txaus siab rau koj qhov kev thov, tsuas yog xav tiv tauj peb.

Cov ntaub ntawv ntim thiab khaws cia

200KG / steel nruas, 1000KG / IBC lossis isotank

Pom zoo cia kub: 10-30 degree

Lub neej txee (hauv cov thawv kaw ntom ntom): 6 lub hlis
