护坡模具的质量标准

一、看。护坡模具的颜色。质量好的护坡模具是用白色聚丙烯塑料注塑而成型的,颜色上通常是白色,若是有杂质掺在里面,就会有微黄的颜色。质量差的护坡模具很多是由粉碎的回料做成的,颜色上存在很多的黑色斑点,模具显得比较浑浊灰暗。 二、摸。护坡模具的表面,质量好的护坡模具外观光滑细腻,而质量次的护坡模具则多有飞边毛刺、刀销等表面粗糙。另外因为质量次的护坡模具多为回料的再加工,其中仍有残留的水泥等,所以重量比单纯用聚丙烯塑料注塑的要重一些。 One, look. The color of the slope mould. Good quality of the slope mold is made of white polypropylene plastic injection molding, the color is usually white, if there are impurities in the inside, there will be a yellowish color. Many of the poor quality slope protection moulds are made of crushed materials. There are many black spots on the color, and the mold is rather muddy and grey. Two, touch. The surface of the slope protection mould, the quality of the slope protection mold is smooth and delicate, and the quality of the slope protection molds is more rough with burrs and pin pins. In addition, because the quality of the slope protection mold is mostly reprocessing, there is still residual cement, so the weight is much heavier than the injection of polypropylene plastic.
