护坡模具聚丙烯材质的加工要求
发布人:管理员   发布时间:2020-11-20

在由聚丙烯加工成型为护坡模具成品或半成品的过程中,“塑化”是一个关键。无论是聚丙烯挤出加工挤出成型还是注射成型,塑化的质量直接关系到产品的内在质量和表面质量
In the process of polypropylene molding into finished or semi-finished products of slope protection mold, "plasticization" is a key. Whether polypropylene extrusion molding or injection molding, the quality of plasticization is directly related to the internal quality and surface quality of the product

因而,如何从工艺、设备及技术上得到好的塑化质量,也就是聚丙烯挤出加工的关键。聚丙烯挤出加工对专用聚丙烯的要求:由于聚丙烯挤出加工制品低温脆性较大,抗冲性差,只有通过配方及工艺的调整,才能增加聚丙烯挤出加工制品的韧性,提高其抗冲性。
Therefore, how to get good plasticizing quality from process, equipment and technology is the key of polypropylene extrusion processing. The requirements of special polypropylene for extrusion processing of polypropylene: due to the brittleness and poor impact resistance of polypropylene extrusion products at low temperature, the toughness and impact resistance of extruded polypropylene products can be increased only by adjusting the formula and process.

      

对聚丙烯挤出加工的专用聚丙烯的要求:聚丙烯经氯化改性后的产物,在生产过程中,为了提高聚丙烯的综合性能,除改进氯化条件,提高氯化技术水平外,选用专用的聚丙烯也是至关重要的
Requirements for special polypropylene for extrusion processing of polypropylene: in order to improve the comprehensive performance of polypropylene after chlorination modification, in addition to improving Chlorination Conditions and improving chlorination technology level, it is also very important to select special polypropylene

具有节能环保特性的环保塑料护坡模具将具有较好的发展前景。在诸多塑料建材品种中,护坡模具产业基础好、市场前景广而备受投资商的青睐,应用状况最好的塑料建材品种之一。
The green plastic slope protection mould with the characteristics of energy saving and environmental protection will have a good development prospect. Among many kinds of plastic building materials, slope protection mould is one of the most popular plastic building materials with good industrial foundation and wide market prospect.
