The effective control method for radiation noise of metal plates is to take vibration reduction measures.

The control methods for the solid sound generated by the compressor mainly include: ensuring correct installation of the compressor in the assembly process, and avoiding additional noise caused by incorrect assembly process; in the system piping, avoiding the internal distortion of the pipeline during the welding Use a compressor with low noise.

Propagation path control Noise control in the noise propagation path uses a combination of vibration reduction and vibration isolation. The outdoor unit is mounted on the wall of the compartment through a mounting bracket. The wall of the compartment is composed of an inner metal skeleton and the outer layer is covered with a thin steel plate, and the vinegar is foamed and filled in the interlayer. When the air conditioner is running, the thin plate vibrates and radiates noise. An effective control method for radiating noise of such a metal plate is to adopt a vibration damping measure, and a damping material is added between the mounting frame and the wall of the car to achieve the purpose of vibration reduction and noise reduction. Since the air conditioner is installed in a constantly moving vehicle, the external vibration easily causes the system to leak or be damaged, and the vibration generated during the operation of the air conditioner causes the cabin to vibrate and generates excessive noise. Therefore, an elastic connection is used between the outdoor unit and the mounting frame to isolate or weaken the transmission of vibration energy, so that most of the solid sound (vibration propagation) is isolated. The vibration isolation system has both positive vibration isolation and negative vibration isolation, but the vibration sources are different.

When the air conditioner works, it mainly considers the vertical direction forced vibration (the car is stopped at this time), and when the vehicle is running, it is a multi-degree-of-freedom vibration system. To solve this problem, we ask the relevant experts to produce the air conditioner for our factory. Developed a special vibration isolator. After the vibration and impact indicators passed, the air conditioner can still work normally.

Detergent

Detergents are products that remove grime and dirt on any surface. They contribute a lot in our daily lives. Detergents are mainly used for cleaning and there are different types of it. Nowadays, the demand for detergents is high, making people get interested in establishing a small-scale sector of their own that is mainly for manufacturing this product.
We are one of the leading detergent raw material suppliers that are reliable and trusted by many,we have been in this field for many years and have exported our detergent raw materials to several countries and region – if you work with us, we guarantee that the raw materials you`ll get from us are all of high-quality.
We mainly supply detergent raw materials powder form and liquid form which used in detergent powder and detergent liquid, such as Sodium Lauryl Ether Sulfate, Linear Alkyl Benzene Sulphonic Acid, Sodium Tripolyphosphate, Sodium Hexametaphosphate , Caustic Soda .
