復合井蓋的優勢所在有以下三點

1.復合井蓋的固化速率比纖維混凝土快幾倍，8小時可脫模，若三班生產，24小時可脫模三次，模具用量雖比石塑多，但卻只有纖維混凝土井蓋的1/6左右，也可低落模具投資。年產萬套井蓋，只需模具10套。

2.復合井蓋是最抱負、較先輩、是其他模具(如橡膠模具、塑料模具、玻璃鋼模具)所不克不及相比的。

3.復合井蓋最突出長處是倒霉用鋼骨架加強，而以玻纖復合加強，屬于GRC型產物。因此，復合井蓋在現在鋼鐵不停漲價的環境下，更有不受影響的上風。由于不含一點鐵，復合井蓋比石塑及纖維混凝土井蓋更防盜。

Where the advantages of composite covers the following three

1 which cure rates several times faster than the fiber concrete, 8 hours to release, if the production of three shifts, the release times may be 24 hours, although the amount of more than Shisu die, but only a fiber reinforced concrete covers about 1/6 , the investment mold may be low. Million units of annual production covers just 10 sets of molds.

2 composite covers most ambitious than our ancestors, other molds (such as rubber molds, plastic molds, fiberglass molds) that can not be compared.

3 It is the most prominent strengths unlucky steel skeleton reinforced with fiberglass composite and strengthened belong GRC-type product. Therefore, it is kept in the current steel price environment, more unaffected hand. Since it does not contain iron, which is more than Shisu theft and fiber reinforced concrete covers.
