DDI (Dimeryl Diisocyanate)

Khoom muag: Dimeryl diisocyanate(DDI 1410) CAS TSIS .: 68239-06-5
Cov mis mos molecular : C36H66N2O2 EINECS : 269-419-6

Kev tuav thiab khaws cia Kev Nyab Xeeb: Kaw Cia YAM RAWS LI TX Kaw Thaum TSIS SIV. COV KHW NYOB RAU HAUV QHOV CHAW QHUAV.

Dimeryl diisocyanate (DDI) yog ib qho tshwj xeeb aliphatic (dimer fatty acid diisocyanate) diisocyanate uas tuaj yeem siv nrog cov tebchaw muaj cov khoom ua muaj hydrogen ua kom npaj qis molecular yuag los yog tshwj xeeb polymers.
DDI yog cov saw ntev ua ke nrog txoj saw tseem ceeb ntawm dimeric fatty acids uas muaj 36 carbon atoms. Tus qauv nraub qaum no muab DDI zoo dua yooj, dej tsis kam thiab muaj tshuaj lom tsawg dua lwm cov aliphatic isocyanates.
DDI yog cov viscosity uas tsis muaj kua uas yooj yim soluble hauv feem ntau polar lossis nonpolar kuab tshuaj.

1) tag nrho cov ntaub ntawv qhia kev hais los saud yog rau koj siv.
2) lwm qhov kev xaiv tshwj xeeb yog txais tos rau kev sib tham ntxiv.
DDI tuaj yeem siv rau hauv cov khoom siv pob zeb ua kom zoo, cov ntaub ua tiav, ntawv, tawv thiab ntaub pleev cov tshuaj, kho cov khoom ntoo, hluav taws xob thiab npaj cov khoom tshwj xeeb ntawm polyurethane (urea) elastomers, nplaum thiab foob, thiab lwm yam.
DDI muaj cov khoom ntawm tsis tshua muaj tshuaj lom, tsis muaj daj, yaj hauv feem ntau cov kuab tshuaj organic, tsis tshua muaj dej thiab tsis muaj viscosity.
Hauv kev lag luam npuag, DDI qhia txog kev thov zoo heev nyob rau hauv dej-pleev cov tshuaj thiab muag cov khoom rau ntaub. Nws yog qhov tsis haum rau dej ntau dua li cov tshuaj tsw qab isocyanates thiab tuaj yeem siv los npaj cov kua dej aqueous emulsions ruaj khov. DDI tuaj yeem txhim kho cov dej ntawm cov tshuaj tiv thaiv dej thiab roj-pleev cov tshuaj rau cov nplaim fluorinated. Thaum siv ua ke, DDI tuaj yeem txhim kho cov tshuaj pleev cov dej thiab cov roj-cov txheej txheem ntawm cov ntaub ntawm cov ntaub.
DDI, npaj los ntawm dimer fatty acids, yog hom ntsuab, bio-txuas ntxiv dua tshiab isocyanate ntau yam. Piv nrog universal isocyanate TDI, MDI, HDI thiab IPDI, DDI tsis muaj tshuaj lom thiab tsis muaj tshuaj lom.
Kev tuav: Zam kev sib cuag nrog dej. Txheeb xyuas kom muaj cua zoo ntawm chaw ua haujlwm.
Cia: Muab cia rau hauv cov thawv kaw nruj nreem, txias thiab qhuav.
Cov ntaub ntawv thauj mus los: tsis yog tswj hwm raws li cov khoom muaj kev phom sij.
