Introduction to the application scope of glass fiber reinforced and modified polypropylene axial flow fan and cross flow fan in refrigerators, air conditioners and other refrigeration machines made of glass fiber reinforced and modified polypropylene generally, the mechanical properties of polypropylene materials themselves are very different from the requirements of engineering structures. Generally, the tensile strength is between 20~30mpa and the bending strength is between 25~50mpa, The bending modulus is 800~1500mpa. If you want to use it in engineering structural parts, you must use glass fiber for reinforcement. Generally, the mechanical properties of polypropylene products reinforced by glass fiber can be doubled or even several times. Specifically, the tensile strength has reached 65~85mpa, the bending strength has reached 70~95mpa, and the bending modulus has reached 3000~4500. Each of us should shoulder the burden of MPa. Such mechanical strength is comparable to that of ABS and reinforced ABS products, and it is more heat-resistant. Generally, the heat resistance temperature of ABS and reinforced ABS is between 80 ℃ ~98 ℃, while the heat resistance temperature of glass fiber reinforced polypropylene can reach 135 ℃ ~145 ℃. It can be used to make axial flow fan and cross flow fan in cuilixin's refrigerator, air conditioner and other refrigeration machines. Gaoxizhu fan, Secretary of Shandong Huayu Party committee and chairman of Shandong Huayu (as shown in Figure 3). 6. During zigzag experiment, its cost is much lower than that of ABS enhanced products or as enhanced products. In addition, it can also be used to manufacture the inner cylinder of high-speed washing machine to meet its high requirements for mechanical performance
