复合井盖的优势所在有以下三点

1.复合井盖的固化速率比纤维混凝土快几倍，8小时可脱模，若三班生产，24小时可脱模三次，模具用量虽比石塑多，但却只有纤维混凝土井盖的1/6左右，也可低落模具投资。年产万套井盖，只需模具10套。

2.复合井盖是最抱负、较先辈、是其他模具(如橡胶模具、塑料模具、玻璃钢模具)所不克不及相比的。

3.复合井盖最突出长处是倒霉用钢骨架加强，而以玻纤复合加强，属于GRC型产物。因此，复合井盖在现在钢铁不停涨价的环境下，更有不受影响的上风。由于不含一点铁，复合井盖比石塑及纤维混凝土井盖更防盗。

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.
