D370 SMC Moulded rwb thaiv tsev ntawv
D370 SMC molded rwb thaiv tsev ntawv (D&F hom naj npawb: DF370) yog ib hom thermosetting nruj rwb thaiv tsev ntawv.Nws yog tsim los ntawm SMC hauv pwm nyob rau hauv qhov kub thiab txias.Nws yog nrog UL ntawv pov thawj thiab dhau qhov kev xeem ntawm REACH thiab RoHS, thiab lwm yam. Nws tseem hu ua SMC ntawv, SMC rwb thaiv tsev board, thiab lwm yam.
SMC yog ib hom ntawv molding compound uas muaj iav fiber reinforced nrog unsaturated polyester resin, ntim nrog hluav taws kub retardant thiab lwm yam khoom filling.
SMC cov nplooj ntawv muaj zog dua txhua yam, lub zog dielectric, nplaim taws zoo, taug qab tsis kam, arc tsis kam thiab siab dua tiv taus hluav taws xob, nrog rau kev nqus dej tsawg, ruaj khov qhov ntev thiab me me dabtsi yog khoov deflection.SMC nplooj ntawv yog siv los ua txhua yam ntawm insulating boards nyob rau hauv siab los yog tsawg voltage hloov zog.Nws kuj tseem siv tau los ua cov txheej txheem ntawm cov txheej txheem rwb thaiv tsev.
