Amfani
4,4'-Diamino-3,3'-dichlorodiphenylmethane (MOCA) wani sinadari ne na halitta, kuma manyan hanyoyin amfani da shi sune kamar haka:
- Haɗa Kayan Polyurethane: MOCA muhimmin mai faɗaɗa sarka ne ga polyurethane elastomers. A cikin samar da polyurethane, isocyanate prepolymers suna buƙatar yin aiki tare da masu faɗaɗa sarka don samar da polymers masu nauyin kwayoyin halitta. MOCA yana da babban amsawa tare da isocyanates, wanda zai iya faɗaɗa sarkar kwayoyin halitta ta polyurethane yadda ya kamata kuma ya inganta tauri, ƙarfi, juriyar lalacewa, juriyar tsagewa da sauran kaddarorin kayan. Ana amfani da shi akai-akai wajen ƙera samfuran elastomer polyurethane masu ɗaukar nauyi, kamar faranti na sieve, na'urorin birgima na roba, hatimi, da sauransu waɗanda ake amfani da su a masana'antu kamar hakar ma'adinai, ƙarfe, da man fetur. Waɗannan samfuran suna buƙatar samun juriyar lalacewa da halayen injiniya.
- Maganin Magance Matsalolin Epoxy Resins: Ana iya amfani da MOCA a matsayin maganin warkarwa ga resin epoxy. Yana yin haɗin gwiwa tare da resin epoxy don samar da tsarin hanyar sadarwa mai girma uku, don haka yana warkar da resin epoxy. Resin epoxy da aka warke suna da kyawawan halayen injiniya, juriya ga lalata sinadarai, da juriya ga zafi. Sau da yawa ana amfani da shi wajen ƙera wasu kayan haɗin epoxy tare da buƙatun aiki mai girma, kamar a fannin kayan tukunya na lantarki da rufin bene. Kayan tukunya na lantarki suna buƙatar kare abubuwan lantarki na ciki daga muhallin waje. Resin epoxy da aka warke tare da haɗin MOCA na iya samar da kyakkyawan hatimi da kariya ta injiniya. Rufin bene na Epoxy yana buƙatar samun halaye kamar juriya ga lalacewa da juriya ga tsatsa don biyan buƙatun amfani na wurare kamar bita na masana'antu da wuraren ajiye motoci.
Marufi da Jigilar Kaya
25KG/jaka ko kuma kamar yadda ake buƙata daga abokin ciniki.
Jigilar kaya: Nau'ikan kayayyaki masu haɗari 6.1 kuma ana iya isar da su ta teku.
Ajiyewa da adanawa
Rayuwar shiryayye: Watanni 24 daga ranar ƙera shi a cikin marufi na asali wanda ba a buɗe ba, an adana shi a wuri mai sanyi da bushewa, ba tare da hasken rana kai tsaye ba, ko ruwa.
Ma'ajiyar iska, Busar da ƙananan zafin jiki, An raba shi da sinadarai masu guba, acid.
