With the different manufacturing areas of the materials produced by various food industry enterprises, the requirements for the use of production operations and the development and broadening of equipment, the production and operation environment of various food industry enterprises are also different, so the planning of various parts of the food conveyor belt is different. How to use o-belt?
In order to be able to better adapt to the production environment, some wear resistance is strong, some can adapt to high temperature environment, choose what kind of belt conveyor parts, determine what operating conditions can be one of the elements of production operation.
The o-belt in food conveyor belt is polyurethane round belt, also known as round belt. Generally, PU material or rubber material is selected for manufacturing. However, due to different manufacturing processes, the standard function of the same kind of rubber also has great changes.
The surface finish of o-belt is better, and the color is gorgeous. The O-type food conveyor belt has two kinds of smooth surface and rough surface, and the color is red and green. The PU round belt has high softness. It is not only resistant to bending and tensile strength, but also resistant to oil, wear and chemical corrosion. It is easy to clean and can be welded quickly. The welded joint is firm and durable, without cracking, detachment and elongation. The appearance is slightly rough, but the particles are uniform and neat, and the handle is soft, so it has a wide range of application.
The o-belt of food conveyor belt also has the characteristics of beautiful appearance, low noise, stable transmission, easy removal and replacement, which is used in food, medicine, beverage and other light industries. At the same time, o-belt can also be used in harsh external environment for a long time. It not only has good damping function, but also has high strength of mechanical operation, high rebound rate of material, good dimensional stability of round belt, and resistance to a variety of solvents, ozone, ultraviolet, etc.
Food conveyor belt is a kind of round belt with liquid crystal function in melt state, which is connected by rigid mediator gene and flexible spacer group. It has good mechanical, thermal stability, high elasticity, high elongation and processing function.

Food conveyor belt itself has good wear resistance and physical aging resistance, but it is not used for a long time. What causes the aging of food belts? Let's take a look at it with Casey.
When rubber is soaked in water or wet air, it is easy to damage. This is because the water-soluble substances and water groups in rubber are extracted and dissolved by water. It is caused by hydrolysis or absorption. Especially under the alternate effect of water immersion and atmospheric exposure, the damage of rubber will be accelerated. However, under certain conditions, moisture does not damage the rubber, and even has the effect of delaying aging.
Increasing temperature can lead to pyrolysis or thermal crosslinking of rubber. But the fundamental effect of heat is still the activation effect. It is a common aging phenomenon - thermal oxidation aging to accelerate the reaction speed of rubber oxidation by improving the diffusion speed of oxygen and activating the reaction of oxidation.
The shorter the light wave, the greater the energy. The damage effect of the rubber is caused by ultraviolet rays with high energy. Ultraviolet radiation can directly cause the cracking and crosslinking of rubber molecular chain. In addition, rubber can absorb light energy and produce free radicals, which can trigger and accelerate the reaction process of oxidation chain. Ultraviolet light has a heating effect. Another characteristic of light effect (different from heat effect) is that it mainly grows on the surface of oak. For samples with high gel content, network cracks will appear on both sides, which is called "light outer layer crack".
In rubber, oxygen reacts with the free radical chain of rubber molecules, and the molecular chain cracks or over crosslinks, resulting in the change of rubber function. Oxidation effect is one of the important reasons for rubber aging.
The chemical activity of ozone is much higher than that of oxygen, and the damage is greater. The molecular chain of ozone is cracked, but the effect of ozone on rubber is different with whether the rubber is deformed or not. When the effect is on the deformed rubber (mainly unsaturated rubber), cracks perpendicular to the direction of stress effect appear, which is called "ozone cracking"; when the effect is on the deformed rubber, only oxide film is formed on the surface of the rubber without cracking.
Under repeated mechanical stress, the continuous friction between the conveyor belt and the idler will cause the rubber molecular chain to crack and generate free radicals, which will cause the reaction of the oxidation chain and form a mechanochemical process. Mechanical cracking of molecular chain and mechanical activation of oxidation process. It depends on the conditions. In addition, ozone cracking is easily caused by stress effect.
