N,N Dimethyl aniline P touldine(CAS: 99-97-8)

Madzi achikasu opepuka okhala ndi mafuta opanda mtundu kapena fungo la mazira ovunda, kutentha kwa 130.31℃, kutentha kwa 211.5-212.5℃, kulemera kwa kutentha kwa chipinda 0.9287~0.9366g/mL, refractive index 1.5360~1.5470, osasungunuka m'madzi, amasungunuka mu organic solvent inayake, amawola akamayikidwa pa kuwala.

Kagwiritsidwe Ntchito: Monga choyambitsa kuwala chogwira ntchito bwino cha acrylonitrile (AN), chimagwiritsidwa ntchito kwambiri popanga zipangizo za mano zodzipangira zokha mwachangu, zipangizo zopangira umbauld ndi zomatira za acrylic anaerobic. Liwiro la polymerization limagwirizana ndi mphamvu ya 1.62 ya kuchuluka kwa AN ndi mphamvu ya 0.62 ya kuchuluka kwa DMT. Chogulitsachi nthawi zambiri chimagwiritsidwa ntchito ngati chowonjezera mphamvu. Kuphatikiza apo, chingagwiritsidwenso ntchito ngati chowonjezera mphamvu cha unsaturated polyester resin ndikugwiritsa ntchito bwino kupititsa patsogolo kutseguka kwa zipolopolo za capsule. DMT ndi chowonjezera mphamvu cha polymerization, monga ma tray a mano opangira mano. Gawo lake lalikulu ndi methyl methacrylate, yokhala ndi peroxide ngati choyambitsa. Njira yodziwika bwino ya polymerization ndi kuuma potenthetsera m'madzi otentha pa 100°C kwa mphindi 40. . Ngati 0.8% ya ma tertiary amines awonjezedwa, monga N,N-dimethyl-p-toluidine ndi N,N-diisopropanol-p-toluidine, mawonekedwewo amatha kuchiritsidwa okha mkati mwa mphindi zochepa kutentha kwa chipinda. Izi zili choncho chifukwa chakuti ma tertiary amines Amine catalysis imathandizira kuwonongeka kwa peroxide kutentha kwa chipinda, motero imathandizira njira yopangira polymer ya methyl methacrylate. Kuwonjezera pa zipangizo zamano, polymerization ya plexiglass yakunja imagwiritsanso ntchito njira yodzipangira yokha. Kuwonjezera 0.8% DMT panthawi ya polymerization kumalimbikitsa polymerization ndi cross-linking. Izi zimapulumutsa ntchito ndi nthawi, ndipo zimatha kusintha kwambiri khalidwe loyambirira. Mphamvu yopanga zida.
