About the composition of SMC insulation board

SMC rwb thaiv tsev board yog ib daim ntawv khoom ntawm ntau yam xim, ua los ntawm unsaturated polyester iav fiber reinforced board molded yas. Sheet molding compound yog cov ntawv luv rau cov ntawv molding compound. Cov ntaub ntawv tseem ceeb yog tsim los ntawm GF (xov paj tshwj xeeb), UP (unsaturated resin), qis shrinkage additives, MD (filler) thiab ntau yam additives.

SMC composite material, a kind of FRP. The main raw materials are composed of GF (special yarn), MD (filler) and various additives.

The unique properties of SMC composite materials can solve the shortcomings of wood, steel and plastic meter boxes, such as easy aging, corrosion, poor insulation, poor cold resistance, poor flame retardancy, and short service life. The SMC composite electric meter box has excellent sealing and waterproof performance, anti-corrosion performance, anti-theft performance, no grounding wire, beautiful appearance, blockage and lead sealing safety protection, and long service life. Composite cable supports, cable trench supports and composite meter boxes are widely used in the transformation of rural and urban power grids.
