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

Sau ntawv
1) tag nrho cov ntaub ntawv kev qhia saum toj no yog rau koj siv.
2) lwm qhov tshwj xeeb yog txais tos rau kev sib tham ntxiv.
DDI tuaj yeem siv rau hauv cov khoom siv foob pob hluav taws, cov ntaub ntawv xov, ntawv, tawv thiab ntaub tiv thaiv, ntoo preservative kho, hluav taws xob potting thiab npaj cov khoom tshwj xeeb ntawm polyurethane (urea) elastomers, nplaum thiab sealant, thiab lwm yam.
DDI muaj cov khoom uas tsis muaj tshuaj lom, tsis muaj yellowing, yaj nyob rau hauv feem ntau cov organic solvents, tsis tshua muaj dej rhiab heev thiab tsawg viscosity.
Hauv kev lag luam Fabric, DDI qhia tau hais tias qhov zoo tshaj plaws daim ntawv thov kev cia siab nyob rau hauv dej-repellent thiab softening zog rau fabrics.Nws yog qhov tsis tshua muaj dej ntau dua li cov tshuaj tsw qab isocyanates thiab tuaj yeem siv los npaj cov emulsion ruaj khov.DDI tuaj yeem txhim kho cov nyhuv ntawm cov dej-repellent thiab roj-repellent rau fluorinated fabrics.Thaum siv ua ke, DDI tuaj yeem txhim kho cov dej-repellent thiab roj-repellent zog ntawm fabrics.
DDI, npaj los ntawm dimer fatty acids, yog ib qho ntsuab, bio-renewable isocyanate ntau yam.Piv nrog rau universal isocyanate TDI, MDI, HDI thiab IPDI, DDI yog non-toxic thiab non-stimulating.
Kev tuav: Tsis txhob sib cuag nrog dej.Xyuas kom muaj qhov cua zoo ntawm qhov chaw ua haujlwm.
Cia: Khaws rau hauv cov thawv kaw kom nruj, txias thiab qhuav.
Cov ntaub ntawv kev thauj mus los: tsis raug tswj raws li cov khoom siv phom sij.
