产品详情

，由于其特性，加工方法和条件与一般塑料有所不同。虽然加工方法仍然使用传统的热塑性复合材料加工方法，但它们也吸收了热固性复合材料加工的一部分。该方法使聚苯硫醚的加工方法更加丰富。PPS树脂通常是白色（接近白色）粉末或珠状产品。根据树脂结构，可分为支化（交联）PPS树脂和线性PPS树脂，因为它们在结构和性能上有一定的差异，导致其加工条件发生一些变化，在加工过程中需要注意。聚苯硫醚树脂具有良好的流动性，可以通过双螺杆挤出机直接挤出，然后通过拉伸或吹塑制备聚苯硫醚纤维、薄膜和各种材料。同时，由于PPS树脂与玻璃纤维、无机填料和金属具有良好的亲和力，因此通过双螺杆挤出机的共混和挤出，很容易制备各种增强改性PPS复合颗粒和制品。制备的各种类型的PPS增强改性复合球团通常首先选择产品成型过程的注射工艺。这种成型方法可以生产各种类型的不同尺寸的精密零件，如齿轮、轴承、连接器等。压力成型可以用于一些特殊产品或小批量的大产品以及大尺寸、大厚度的扁平产品。烧结成型可生产聚苯硫醚棒、片材或空心制品。它在小规模生产中更实用，可以降低机器成本，但其产品性能不如注塑产品。涂层是一种特殊的聚苯硫醚成型方法。可采用悬浮浸渍、悬浮喷涂、粉末火焰喷涂、干粉静电喷涂、流化床喷涂等方法。其中，悬浮法和干粉火焰喷涂法是制备耐温、防污、防污涂料的主要方法。聚苯硫醚粘合剂涂层，用于各种恶劣环境

Product Details

Injection pps plastic resin

As a crystalline high-melting polymer, the processing methods and conditions are somewhat different from general plastics due to its characteristics. Although the processing methods still use traditional thermoplastic composite processing methods, they also absorb part of the processing of thermoset composites. The method makes the processing methods of PPS more abundant. PPS resin is usually a white (near white) powder or bead product. According to the resin structure, it can be divided into branched (crosslinked) PPS resin and linear PPS resin, because they have certain differences in structure and performance. , Resulting in some changes in its processing conditions, which need to be paid attention to during the processing. PPS resin has good fluidity and can be directly extruded by a twin-screw extruder, and then PPS fibers and films and various types of materials can be prepared by stretching or blow molding. At the same time, because PPS resin has good affinity with glass fiber, inorganic fillers and metals, it is easy to prepare various reinforced and modified PPS composite pellets and products through blending and extrusion with a twin-screw extruder. The prepared various types of PPS reinforced modified composite pellets usually first select the injection process for the molding process of the product. This molding method can produce various types of precision parts of different sizes, such as gears, bearings, connectors, etc. Press molding can be used for some special products or large products with small quantity and flat products with large size and large thickness. Sintering molding can produce PPS rods, sheets or hollow products. It is more practical in small-scale production and can reduce machine costs, but its product performance is not as good as injection molded products. Coating is a special kind of PPS molding method. Suspension dipping, suspension spraying, powder flame spraying, dry powder electrostatic spraying, fluidized bed coating and other methods can be used. Among them, suspension and dry powder flame spraying are the main methods to make temperature resistant, anti-fouling and antifouling. Adhesive PPS coating, used in various harsh environments.
