復(fù)合井蓋的優(yōu)勢(shì)所在有以下三點(diǎn)

1.復(fù)合井蓋的固化速率比纖維混凝土快幾倍，8小時(shí)可脫模，若三班生產(chǎn)，24小時(shí)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(chǎn)萬套井蓋，只需模具10套。

2.復(fù)合井蓋是最抱負(fù)、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(fù)合井蓋最突出長處是倒霉用鋼骨架加強(qiáng)，而以玻纖復(fù)合加強(qiáng)，屬于GRC型產(chǎn)物。因此，復(fù)合井蓋在現(xiàn)在鋼鐵不停漲價(jià)的環(huán)境下，更有不受影響的上風(fēng)。由于不含一點(diǎn)鐵，復(fù)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.
