What Should Be Noted in the Installation and Use of Polyurethane Wheels？
Aug. 25, 2020
PU Wheels need to pay attention to many issues during the installation and use of the equipment. During the installation and use of the equipment, the staff must first clarify the working method of the equipment and the functional requirements. Some equipment is in the process of making There are certain limitations in functions. Such equipment can only be installed and used in some processing industries, so the selection of equipment needs to be paid attention to.
During the purchase of equipment, the staff must also clarify the use conditions and application scope of the equipment and other factors, and select suitable equipment for installation and application in accordance with the above standards. During the use of polyurethane casters, the product should reach a certain load standard.
The load standard refers to the load-bearing effect of the equipment. Some equipment can bear a relatively large weight range during work, and some equipment cannot bear a large weight. These differences are also issues that people should pay attention to when selecting equipment. It is also possible to estimate the load-bearing range before selecting the equipment and combine these application requirements to select the appropriate roller for application.
PU Castor Wheels
The elasticity of PU Castor Wheels is closely related to many factors, including the composition of the polyurethane, the thickness of the polyurethane, and whether it is doped with other chemicals; it is also related to the temperature, and the external temperature will affect the hardness and hardness of the polyurethane The elasticity of oversized polyurethane casters is also very limited
Polyurethane casters have physical functions. Temporary use of rubber rollers will not harden and age, and has good tear resistance and rebound functions. Moreover, polyurethane casters can accept high pressure, high speed, high humidity environment; suitable for various types of inks and printing methods, and have special resistance to solvent components in various inks, fountain solutions, and cleaning agents.
Different industrial accessories products have different wear in different fields of use. The degree of wear between them is related to its coefficient of friction. The coefficient of friction refers to the friction between two surfaces and acting on one of the surfaces. The ratio of the vertical force. It is the ratio of starting resistance and rolling resistance, which can be measured by measuring traction.
The friction coefficient of polyurethane casters is related to the material properties and surface conditions (roughness, humidity, etc.) of the objects in contact with each other.
Polyurethane casters have strong physical and mechanical properties, but in actual use, they can also show better wear resistance. Therefore, even if they are used for a long time, their surface will not wear. Its structure is usually covered with soft materials on the metal wheel core.
Industrial PU Wheels mainly includes a metal wheel core and a polyurethane layer. The polyurethane layer is concentrically wrapped on the outer circumferential surface of the metal wheel core. The soft material used at the beginning is nitrile rubber, and later to improve the roller The wear resistance and load-bearing capacity of the polyurethane material gradually replaced the nitrile rubber, and polyurethane casters appeared.
Because of its load-bearing capacity and wear resistance are significantly better than rollers made of other soft materials, and it has the advantages of lightness, it has been widely used. When the polyurethane casters work, there are three ways for the endogenous heat of the polyurethane layer to be dissipated: one is that the polyurethane casters are in contact with the surface of the walking track and dissipate heat by conduction. The second is that the surface of the polyurethane layer and the air dissipate heat in a convective manner; the third is that the polyurethane layer and the wheel core dissipate heat in a conductive manner.
