This article is about SMC, not original by me, I think it is good, I reprint it, I hope to share it with you, to understand the SMC and SMC manhole cover.
SMC is the short form of Sheet Moulding Compound. It is composed of resin , fiberglass and other chemical polymer. This a raw material for mold pressing .
The core is chopped strand and unsaturated polyester resins paste that are covered by LDPE&HDPE sheet , with a thickness of 3mm-6mm,600mm-1200mm width and is packed in rolls or boxes .
During production ,to cut , weigh the raw material and then put it into a mould opening. After a high pressure and temperature preservation for set time, final product is finished and will be transported to next working station.
SMC manhole cover is a kind of FRP manhole cover which is a kind of sheet material cover that developed by us, which is short for Sheet Moulding Compound . It is made up of fiberglass and unsaturated polyester resin . Comparing with other material , it has a higher stretch resistance and bend resistance .
Comparing with the traditional ductile cast iron , SMC manhole cover owns very similar or even better performance at testing load rating. SMC manhole cover is able to meet and xceed A15/B125/C250/D400/E600/F900 loading rating, according to EN124 .Meanwhile , SMC manhole cover well solves the theft and potential problems caused by thieves , as SMC is zero recycle value .
Advantages of SMC manhole cover compare with other material :
1,Higher stretch resistance and bend resistance .
2,Anti-theft , no recycle value.
3,Light-weighted.
4,Durable service life.
5,Anti-corrision , anti-slip.
6,UV-proof and V0-flammability rating.
