高速公路階梯式護(hù)坡模具定制注塑成型后表面產(chǎn)生黑斑黑紋的情況。黑斑和黑紋是階梯護(hù)坡模具定制表面呈現(xiàn)暗色點(diǎn)或暗色條紋，褐斑和褐紋相同類型的瑕疵只是燃燒或掉色的污染的程度沒有那么嚴(yán)重而已。高速公路階梯式護(hù)坡模具的差異是在于模具的形狀不同，而且高速公路階梯式護(hù)坡模具所應(yīng)用的工程領(lǐng)域不一樣，實(shí)心護(hù)坡磚模具常用在橋頭或者河道護(hù)坡，而空心護(hù)坡磚應(yīng)用廣泛。Black spots and black lines on the surface after customized injection molding of stepped slope protection mold. Black spots and black lines are the customized surface of the stepped slope protection mold, showing dark spots or dark stripes. The same type of defects as brown spots and brown lines are just that the degree of combustion or fading pollution is not so serious. The difference between the slope protection mold and the hollow slope protection mold lies in the different shape of the mold, and the engineering fields applied by the solid slope protection mold and the hollow slope protection mold are different. The solid slope protection brick mold is commonly used in bridge head or river slope protection, while the hollow slope protection brick is widely used.
