Daim ntawv thov
4,4'-Methylenedianiline yog ib qho tseem ceeb tshuaj nruab nrab, uas yog siv los ua raw khoom rau kev tsim diisocyanate, polyamide, antioxidant, corrosion inhibitor, thiab lwm yam; Nws yog lub ntsiab monomer rau zus tau tej cov carbamate thiab diisocyanate. Nws yog siv los ua cov saw txuas ntxiv rau kev tsim cov kub-resistant polyimide enameled hlau xim, hluav taws xob rwb thaiv tsev laminates, polyamides, aerospace high-temperature resistant coatings, tshav kub-resistant polymers, thiab polyurethane elastomers. Cov khoom zoo tshaj plaws ntawm cov resin los yog kub resistant polymer ua nrog nws yog kub tsis kam, zoo rwb thaiv tsev, siab zog, zoo hnav tsis kam thiab tshuaj stability. Nws tuaj yeem ua rau hauv cov yeeb yaj kiab nyias, cov khoom siv molded, cov xim hlau, thiab lwm yam. Nws kuj yog siv rau sab hauv thiab sab nrauv ntawm cov hluav taws kub-resistant cables, interlayer rwb thaiv tsev ntawm transformers, thiab gaskets ntawm motors. Nws yog siv los ua antioxidant rau chloroprene roj hmab, butyl roj hmab, roj hmab ntuj, thiab styrene butadiene roj hmab, nrog rau kev laus tiv thaiv kev ua haujlwm; Nws kuj yog ib tug muaj zog active neeg sawv cev. Nws tseem tuaj yeem siv los ua tus neeg sawv cev kho rau epoxy resins, nrog cov khoom zoo ib yam li m-phenylenediamine, haum rau castings, laminates, adhesives, thiab coatings.
