Cov ntaub ntawv tseem ceeb ntawm cov khoom

Engineered los ntawm kev tswj catalytic kua-theem hloov kho nyob rau hauv nitrogen daim pam, qhov hloov kho diphenylmethane diisocyanate tseem ua kua ntawm qhov kub thiab txias. Nws yog tsim los tshem tawm cov kev sib tw khov thiab crystallization cuam tshuam nrog cov ntshiab 4,4'-MDI, kom ntseeg tau tias muaj kev cuam tshuam zoo ib yam thiab txuas ntxiv kev ruaj ntseg rau polyurethane ua npuas ncauj thiab elastomer formulation.

Manufacturing Control:Synthesized nyob rau hauv kaw- voj reactors nrog tiag -lub sij hawm kub thiab siab txiav txim kom muaj xws li NCO tis thiab txo monomeric MDI fluctuations ntawm ntau lawm campaigns.

Core Function:Ua hauj lwm raws li thawj reactive diisocyanate tivthaiv nyob rau hauv nruj rwb thaiv tsev systems, CASE formulations, thiab molded structural Cheebtsam.

FAQ

Q: Hloov kho MDI li cas tiv thaiv qis -kub crystallization?

A: Kev hloov kho tshuaj los ntawm uretonimine lossis prepolymerization cuam tshuam qhov kev sib xyaw ua ke ntawm cov ntshiab 4,4'-MDI molecules, khaws cov khoom ua kua thiab nqus tau ntawm cov khoom ntim khoom kub.

Q: Dab tsi yog qhov pov thawj lub neej txee?

A: 6 lub hlis txij li hnub tsim khoom thaum khaws cia rau hauv qhov tsis tau qhib, cov thawv qub raws li kev pom zoo (15 ° C txog 35 ° C).

Q: Koj puas tuaj yeem ua raws li cov kev cai tshwj xeeb rau loj - nplai ntau lawm?

A: Yog. Rau kev pom zoo txhua xyoo rov ua dua, peb pawg kws tshaj lij tuaj yeem ua kom zoo - kho qhov sib piv prepolymer kom phim koj cov kev ua haujlwm tshwj xeeb.
