style="font-size:14px;">BMC模壓井蓋：是用不飽和樹脂作基本材料，用30-50mm短纖維和鋼筋作增強(qiáng)材料，用碳酸鈣作填充材料，在一定溫度下壓制而成。由于鋼筋是金屬材料，而BMC是有機(jī)材料，BMC的熱膨脹系數(shù)是鋼筋的兩倍，且因鋼筋表面生銹</span><span style="font-size:14px;">，而使BMC與之復(fù)合時界面結(jié)合不牢，溫度發(fā)生變化時，鋼筋與BMC材料之間界面會形成應(yīng)力，加之車輛反復(fù)碾壓，會導(dǎo)致鋼筋與BMC界面分離，蕞后井蓋喪失承載能力。并且表面為BMC和碳酸鈣材料混合物，因而耐磨性較差。井蓋分為球墨鑄鐵井蓋、球墨井蓋、鑄鐵井蓋、高分子復(fù)合井蓋、防沉降井蓋、水泥井蓋、隱形井蓋、藝術(shù)井蓋、不銹鋼井蓋、五防井蓋、輕型井蓋、重型井蓋。所有的產(chǎn)品，規(guī)格型號可根據(jù)客戶要求定做（昆明多果商貿(mào)有限公司）。</span>
