济南耐力板发脆的主要原因是什么

来源:http://www.wanzhongyue.com/ 日期:2020-05-21 发布人:julong 浏览次数:

  济南耐力板在遮雨顶棚、农业温室和饲养棚,现代生态餐厅天花板的这几个方面得到了广泛的应用,由于其耐冲击性,拱门,灵活,良好的可加工性,可塑性高,防紫外线的优点,不易碎,深受消费者喜爱,但耐力板工厂的增加,现在的市场变得越来越复杂,客户反应也买PC耐力板容易脆弱,导致PC耐力板发脆的原因有很多,下面就拿阳光板带我们去看看:
  Jinan endurable board has been widely used in rain proof ceiling, agricultural greenhouse, breeding shed and modern ecological restaurant ceiling. Because of its impact resistance, arch, flexibility, good processability, high plasticity and UV resistance, it is not fragile and popular with consumers. However, with the increase of endurable board factories, the market is becoming more and more complex, The customer said that it's easy to buy PC endurance board. There are many reasons for the crispness of PC endurance board. Let's take the sunshine board to have a look:
  济南耐力板加工技术问题:

  Jinan endurance board processing technology problems:
  1、如果生产的原料(聚碳酸酯)很容易降解,那就意味着桶和喷嘴的温度过低,温度应适当提高。
  1. If the raw material (polycarbonate) produced is easy to degrade, it means that the temperature of barrel and nozzle is too low, and the temperature should be increased appropriately.
  2、可适当降低螺杆预成型后的背压和转速,使原料有点松动,并可通过降低PC耐力板因剪切过热而引起的退化。
  2. It can reduce the back pressure and rotation speed after the screw preformed, make the raw material a little loose, and reduce the degradation of PC endurance board caused by shear overheating.
  3、如果模具温度过低,塑料可能会发生过早冷却,导致熔接接头熔合不好,很容易造成开裂,尤其是在使用聚碳酸酯等熔点高的塑料原料时更需要这样做。
  3. If the mold temperature is too low, the plastic may be cooled too early, resulting in poor fusion of the fusion joint, which is easy to cause cracking, especially when using high melting point plastic materials such as polycarbonate.
  因为型腔芯必须有合适的脱模角度。当模芯难以取出时,需要提高模腔温度以缩短冷却时间,降低模腔温度以延长冷却时间。
  Because the cavity core must have a proper demoulding angle. When the core is difficult to take out, it is necessary to increase the cavity temperature to shorten the cooling time and reduce the cavity temperature to extend the cooling time.
  济南耐力板材料问题:
  Jinan endurance board material problem:
  1、在生产耐力板时,加工原料添加回收材料,或用不适当的、过量的溶剂等添加剂,造成耐力板生产发脆现象。
  1. In the production of endurance board, the raw materials for processing are added with recycled materials, or additives such as inappropriate and excessive solvents are used, resulting in brittle production of endurance board.
  2、如果再生的原料数量过多或原料含量过高,还可能促进零件的发脆。
  2. If the quantity of recycled raw materials is too much or the content of raw materials is too high, it may also promote the embrittlement of parts.
  3、使用PC耐力板原料本身质量不好,如分子量分布过大,且组成结构不均匀过大,也容易造成成品发脆开裂。
  3. The quality of PC endurance board raw materials is not good, such as the molecular weight distribution is too large, and the composition structure is not uniform and too large, it is also easy to cause brittle cracking of the finished products.
  4、原料可能被其他塑料污染,或被不良的添加剂、灰尘和杂质污染,这也是发脆的主要原因。
  4. Raw materials may be contaminated by other plastics, or by poor additives, dust and impurities, which is also the main reason for brittleness.
  通过介绍我们知道PC耐力板容易发脆的原因主要有两个方面,耐力板加工技术和耐力板的原材料,我们在选购时,选择合适的济南阳光板工厂,这样可以确保产品的质量,你也可以把阳光板,阳光板、耐力板生产厂家,有需要可以联系。
  Through the introduction, we know that there are two main reasons for the brittleness of PC endurance board: the processing technology of endurance board and the raw materials of endurance board. When we choose and purchase, we choose the appropriate Jinan sunshine board factory, which can ensure the quality of products. You can also contact the manufacturers of sunshine board, specialized sunshine board and endurance board if necessary.
