Rubber diaphragm is a round rubber diaphragm widely used in water pumps, air pumps, valves, and automobile brakes. It has the advantages of low cost, long service life, and aging resistance. The quality of the product will directly affect the performance of the knife equipment. So do you know what factors affect the quality of rubber diaphragm products? Not much gossip goes straight into the subject.
EPDM ， NBR, NR,FKM 等材料的物理性能决定了橡胶制品的物理性能，比如拉伸强度，伸长率，耐高低温等。 The first rubber raw material and rubber diaphragm are different according to the application environment. The physical properties of materials such as EPDM , NBR, NR, FKM and other materials determine the physical properties of rubber products , such as tensile strength, elongation, and high and low temperature resistance. .
The second mold, as the saying goes, the mold is the mother of industry. I strongly agree with this view. The design and processing of the mold have an inseparable relationship with the shape and dimensional accuracy of the product. The dimensional accuracy of the product will have a significant impact on assembly accuracy and sealing performance. influences.
成型参数的三要素温度，压力，时间，如果设定的不合理就会导致产品外观缺陷，比如产品缺料，气泡，烧焦，硫化不良等。 The third rubber diaphragm molding process. With the materials and molds, it is the most critical step to "mold" the three elements of the molding parameters: temperature, pressure, and time. If the settings are not reasonable, it will lead to product appearance defects, such as product shortage. Materials, bubbles, scorching, poor vulcanization, etc.
