应该怎样选用塑料原料

   塑料材料的种类越来越多，因此许多人在选择时往往徘徊不定，下面由专业的塑料原料厂家为您介绍一下在选用塑料时应该注意些什么：

There are more and more kinds of plastic materials, therefore many people often get confused when it comes to decision making. The following is an introduction from plastic material manufacturer in terms of what you should pay attention to when choosing plastics:

      首先，在选用塑料材料时，不能只是简单地将金属制品的选材方法移用过来，因为塑料于金属的性能差异很大，塑料属于粘弹性材料，它的许多性能受环境条件影响十分显著，它的承载能力和应用速度受环境温度变化的影响也很大。所以，只有充分了解各种塑料的性能极限，才能选用到最适宜的原料品种，使设计的制品能够满足各种苛刻和复杂的使用条件，确保产品质量的可靠性。另外，在选材时应综合考虑塑料原料的力学性能及其他性能，如强度、模具、冲击性能、疲劳性能等。还有应该根据实际情况具体分析，尤其是要注意该制品的使用环境、应用要求、测试条件、生产成本和经济效益。

First of all, in the selection of plastic materials, we cannot simply adopt the selection criteria of metal products. Because the properties of plastics are very different from metals, plastics are viscoelastic materials, and many of its properties are affected by environmental conditions. The carrying capacity and speed of application are also affected by changes in the ambient temperature. Therefore, we select suitable raw material varieties only by fully understanding the limits of the performance of various plastics, so that the designed products can meet a variety of harsh and complex conditions of use to ensure the reliability of product quality. In addition, the mechanical properties and other properties of plastic raw materials such as strength, mold, impact properties, and fatigue properties should be collectively considered when selecting materials. There should be specific analysis based on the actual scenario concerned, especially the use of the product environment, application requirements, test conditions, production costs and economic benefits.

以上就是选用塑料原料时应该考虑的情况，希望您从中能更加了解到塑料原料。

These are the criteria guidance that should be taken into account when selecting plastic materials. I hope that you are more familiar with plastic materials.
