What are the significant advantages of neoprene outer coverings over other materials in terms of resistance to oil, solvents, acids and alkalis?

In the mechanical transmission system, lubricating oil is an indispensable part, but long-term infiltration poses a severe test to the stability of rubber synchronous belts. The chloroprene rubber outer coating has significant advantages in oil resistance compared with other materials such as nitrile rubber and polyurethane. The unique chlorine atom polar group in the chloroprene rubber molecule not only enhances the intermolecular force, but also significantly improves the resistance of rubber to oily substances. This means that in an industrial environment containing various mechanical lubricants, the chloroprene rubber outer coating can maintain its physical and chemical stability for a long time, effectively prevent oil penetration and expansion, and ensure the cleanliness and smoothness of the transmission surface. Thereby improving transmission efficiency and reducing energy loss.

In addition to oil resistance, the chloroprene rubber outer coating also has excellent solvent resistance, acid resistance, and alkali resistance. In the chemical, pharmaceutical and other industries, it is often necessary to face the erosion of various organic solvents and acid and alkali solutions. These chemicals are often highly corrosive and soluble, posing a serious threat to the stability of rubber materials. However, due to its unique molecular structure and chemical stability, chloroprene rubber can effectively resist the erosion of these corrosive substances. The chlorine atoms in its molecular chain not only increase the polarity of the rubber, but also improve the resistance of the rubber molecules to solvents and acid-base substances, ensuring that it can maintain stable performance in complex and changeable industrial environments.

The reason why the chloroprene rubber outer coating has achieved such significant advantages in oil resistance, solvent resistance, acid and alkali resistance is due to the technological innovation and process improvement behind it. In the production process, by carefully controlling the polymerization reaction conditions of the chloroprene monomer, chloroprene rubber with excellent performance can be produced. At the same time, the use of advanced surface treatment technology and coating technology can further enhance the protective performance of the chloroprene rubber outer coating, making it more adaptable to complex and changeable industrial environments.

Due to its excellent chemical stability, the chloroprene rubber outer coating is widely used in various fields. In the transmission system, it is used as the outer coating of the rubber synchronous belt, which can effectively improve the transmission efficiency and extend the service life; in chemical equipment, it is used as an anti-corrosion coating and sealing material to resist the erosion of acid and alkali solutions, ensuring the durability and safe operation of the equipment; in the food, medical and other industries, it is also favored for its good biocompatibility and non-toxicity.

  • Rubber Wide - Angle Belt
    Rubber Wide - Angle Belt
    The wide-angle belt is a new type of industrial transmission belt developed on the basis of the general industrial V-belt technology.
    They are all driven by the friction diagram on both sides of the belt. The wedge angle of the general V-belt is 40° and the wedge angle
    of the wide-angle transmission belt is 60°.
    According to the principle of transmission dynamics, as the wedge angle of the wide-angle belt increases, the area supported by the
    two transmission sides naturally increases, thus giving rise to the following advantages over the general V-belt:
    1. The load of the wide-angle belt is evenly distributed and the wear resistance is improved.
    2. The contact area between the belt and the pulley increases and the transmission force is increased.
    3. It improves the concave deformation of the drive belt core and strengthens the drive characteristics.
    4. After the wide-angle belt is installed and used, the problem of belt tension drop is improved.
    It is the above-mentioned advantages of the wide-angle belt that are widely used and affirmed by the precision machinery industry.

  • Rubber Conveyor Belt
    Rubber Conveyor Belt
    The conveyor belt is composed of surface adhesive, core, and layer glue. In addition, a layer of buffer cloth can be added to the use of high drop impact to make it more impact-resistant.

    The surface adhesive
    With natural rubber and synthetic rubber as raw materials and in order to enhance wear resistance, crack resistance, aging resistance, and other properties, the surface adhesive has various characteristics such as wear resistance, cutting resistance, heat resistance, flame resistance, cold resistance, acid and alkali resistance, oil resistance, static electricity resistance and so on.
    Cloth layer core
    The cloth layer is composed of natural fiber or chemical fiber alone or a combination of the two, has the same quality after single-step treatment by a mature process, And has good adhesion with rubber.
    The adhesive layer
    The adhesive layer is very important for the adhesive force between the layers of the core of the conveyor belt that is repeatedly flexed. Especially for high-tension conveyor belts, a layer of adhesive with less buckling stress and less fatigue due to internal stress must be used.
    Specifications and models can be customized according to customer requirements, with a thickness ranging from 2.0 mm to 8.0 mm.
