The dismantling and cleaning of the equipment and the dismantling and cleaning of the oil protection equipment are the key elements of the unit body, including the transmission, crankcase and oil hole slots. For lubricating oil equipment, it is mainly oil coolers, tanks, high tanks, accumulators, oil filters and oil pumps. Cleaning of transmissions and crankcases must be performed carefully due to their large volume and complex construction. It should be checked whether there are any iron scraps and impurities in each corner. If there are any foreign materials, they must be removed and cleaned one by one.
Sometimes because the factory is not well cleaned, the site must be cleaned repeatedly after repeated cleaning. Each oil hole and oil sump must be repeatedly purged with compressed air and then washed with kerosene. Sometimes steel wire can be used to pull through and wash. For oil coolers, accumulators and fuel tanks, due to the presence of a large amount of rust, the manufacturer has not cleaned it. According to the experience of Japan and West Germany, the best method is pickling. It is difficult to remove the net by other methods. The cleaned equipment should be protected by lubricating oil, and the opening of the equipment should be sealed to prevent foreign matter from entering the equipment.
During the process of dismantling and washing the equipment, yarn heads, cotton cloths, flannelettes or other short fiber materials cannot be used for cleaning and applying sponges and plastic foams for cleaning. Because the fiber heads of cotton heads and cotton fabrics can easily adhere to the inner wall of equipment, it will seriously contaminate the oil and lubricant, block the oil filter, reduce the oil supply, and affect the oil flushing of the unit.
Auxiliary agents, also known as additives, are substances that are added to a material to improve or modify its properties. In the field of polymers, auxiliary agents are commonly used to enhance the processing, performance, and durability of polymer materials.
There are several types of auxiliary agents, each with its own unique properties and applications. The most common type is processing aids, which are added to polymer materials to improve their flow and moldability during processing. Processing aids can improve the surface finish of the final product and reduce the amount of energy required during processing.
Another type of auxiliary agent is plasticizers, which are added to polymer materials to increase their flexibility and reduce their brittleness. Plasticizers can improve the toughness and impact resistance of the final product and are commonly used in the production of flexible PVC products, such as hoses and films.
Other types of auxiliary agents include stabilizers, which are added to polymer materials to protect them from degradation caused by heat, light, or chemical exposure. Stabilizers can improve the durability and longevity of the final product and are commonly used in outdoor applications, such as building materials and automotive parts.
Colorants, fillers, and flame retardants are also common types of auxiliary agents. Colorants are added to polymer materials to give them a specific color, while fillers are added to improve the mechanical properties of the final product, such as its strength and stiffness. Flame retardants are added to polymer materials to reduce the risk of fire and are commonly used in applications where fire safety is critical, such as building materials and electronics.
The choice of auxiliary agent depends on the specific application requirements and must be carefully considered to ensure that the final product meets the desired specifications. It is important to select the appropriate auxiliary agent to achieve the desired performance, processing, and durability characteristics of the polymer material.
In summary, auxiliary agents play an important role in the processing, performance, and durability of polymer materials. There are several types of auxiliary agents, each with its own unique properties and applications, and the choice of auxiliary agent depends on the specific application requirements.
