Wobetumi akyekyɛ Explosion-proof panels mu ayɛ no ahorow a edidi so yi a egyina wɔn nneɛma so:
Fiber cement board explosion-proof panels: Wɔde Portland cement na ɛyɛ saa panels yi, a wɔde abɔdeɛ mu nhama (te sɛ nnua nhama) ne aboɔden aboɔ (te sɛ silica anhwea) ka ho. Wɔnam akwan horow te sɛ pulping, molding, ne autoclaving so na ɛyɛ. Saa panels yi ma ahoɔden a ɛkorɔn ne ogya a ɛko tia yiye (a ogya a ɛko tia anohyeto a ɛboro nnɔnhwerew 4) na etumi gyina ɔpae nhyɛso a ɛyɛ 0.1-0.3 MPa ano.
