Do you know about composite materials for overheated shrink film packaging machines? Let's take a look.
 
1. The concept of composite materials for heat shrinkable film packaging machines:
 
With the development of modern machinery, electronics, chemicals, national defense and other industries, and the advancement of high-tech information, lasers, and automation, the requirements for material performance are getting higher and higher. In addition to requiring materials to have high specific strength, high specific modulus, high temperature resistance, fatigue resistance, etc., special requirements are also placed on the material's wear resistance, dimensional stability, shock absorption, non-magnetic, and insulating properties, and even some The components require materials with contradictory properties at the same time. For example, it is both conductive and thermally insulated; its density is smaller than steel, but it is more elastic and stronger than rubber.
This is powerless for single cermet and polymer materials. If composite technology is used, some materials with different properties are combined, and these performance requirements can be achieved by taking advantage of each other's strengths, and modern composite materials have emerged as the times require.
 
The so-called heat shrinkable film packaging machine composite material refers to a multi-phase material that is artificially synthesized by two or more materials with different properties through different process methods, and has obvious interfaces between each component and has better performance than each component material. In order to meet the performance requirements, people "composite" between different non-metals, between metals and between metals and non-metals, so that it not only maintains the characteristics of the constituent materials, but also has new characteristics after the combination. Some properties often exceed the sum of the properties of the constituent materials, thus giving full play to the performance potential of the material. "Composite" has become a means of material performance, and composite materials have been used more and more widely.
 
There are many types of composite materials for heat shrinkable film packaging machines. According to different matrix materials, composite materials can be divided into two categories; the classification of non-metal matrix composite materials and metal matrix composite materials.
 
①Metal-based composite materials, which can be further divided into: inorganic non-metal-based composite materials, materials and other non-gold material-based composite materials, such as material-based, rubber-based composites such as mesh-based and water-mixed composites.
 
②Metal-based composite materials, such as aluminum-based, copper-based, preservative, and titanium-based composite materials, can be divided into three types of composite materials; fiber-reinforced composite materials, particle-reinforced composite materials, and composite materials.
 
Fiber-reinforced composite materials, such as fiber-reinforced plastics, fiber-reinforced rubber, fiber-reinforced ceramics, and fiber-reinforced gold.
 
 
Particle-reinforced composite materials, such as Jinfeng ceramics, sintered dispersion hardening alloys, etc.
 
Laminated composite materials, such as double-layer metal composite materials and three-layer composite materials.
 
(1) When emphasizing the collective, use the collective as the main name. Such as metal composites,
 
(2) When emphasizing the reinforcement material, the reinforcement material is the main name, such as carbon fiber reinforced composite material
 
(3) The matrix and reinforcement materials are used together. This nomenclature is often used to refer to a specific composite material. Generally, the name of the reinforcement material is placed in the front and the name of the matrix material is placed in the back. "Composite materials" are carbon fiber reinforced lead alloy composite materials.
 
(4) Commercial name naming. For example, "Glass Reinforced Plastics" is the performance characteristics of the heat shrinkable film packaging machine composite material of the glass fiber reinforced resin matrix composite material
 
Although there are many types of composite materials for heat shrinkable film packaging machines with different properties, different types of composite materials have some of the same properties.
 
Heat shrinkable film packaging machine composite material has high specific strength and specific modulus
 
The ratio of strength and elastic modulus to density are called specific strength and specific modulus, respectively. They are an important indicator to measure the carrying capacity of materials. The higher the specific strength, the lower the weight of the same part under the same strength; the greater the specific modulus, the greater the rigidity of the part under the same weight.
 
 
Good performance of composite material for heat shrinkable film packaging machine
 
Because fiber-reinforced composite materials, especially fiber-resin composite materials, have little stress concentration on the notch, the surface and the fiber and matrix interface can prevent fatigue crack propagation and change the direction of crack propagation.
 
There are a large number of fibers in the composite material of the heat shrinkable film packaging machine, with an average of thousands to tens of thousands of fibers per cubic centimeter of area. When a small number of fibers break due to overload or other reasons, the load will be redistributed to other unbroken fibers. Therefore, the member will not suddenly break in a short period of time, so the breakage is good.
 
I hope that the above information about composite materials for heat shrinkable film packaging machines is helpful to you.
