Material preparation of oil filters is a key step to ensure their filtration performance and service life. The following are the main aspects of oil filter material preparation:
First, filter medium material
Filter paper:
Features: Commonly used in air compressor oil filter, with excellent filtration performance and certain strength.
Application: According to the different filtration accuracy, filter paper can be divided into coarse filter paper, ordinary filter paper, precision filter paper, etc., which are used to filter impurities of different sizes.
Stainless steel material:
Characteristics: corrosion resistance, high strength, high temperature resistance.
Application: Stainless steel porous plate, stainless steel braided mesh and stainless steel sintered mesh, etc., can be used to make basket filter and other oil filters.
Chemical fiber, glass fiber material:
Features: good filtration performance and corrosion resistance.
Application: Often used to make filter element, used for oil filtration.
Polypropylene composite filter membrane:
Features: Advanced fixed deep filter material with a wide range of filtration accuracy.
Application: It can be used for folding filter element to provide efficient filtration effect.
Activated carbon material:
Features: dual function of filtration and purification, can adsorb impurities and peculiar smell in oil.
Application: It is often used to make activated carbon filter, but it should be noted that its pressure bearing capacity is weak, mainly suitable for low pressure environment.
Two, support and sealing materials
Metal frame:
It is used to support the filter medium and ensure the structural stability of the filter element.
Common materials include tin-plated iron, stainless steel, etc.
O ring:
Used to seal the oil filter to prevent oil leakage.
It is necessary to ensure that the specifications are accurate and check whether the elasticity and hardness are suitable.
Iii. Other auxiliary materials
Adhesive:
It is used to glue the filter medium and the support material together to ensure the integrity of the filter element.
It is necessary to choose high temperature and corrosion resistant adhesives.
Packing Materials:
Used to protect the oil filter from damage during transportation and storage.
Common materials include plastic bags, cartons, etc.
4. Material selection and precautions
Select materials according to filtration requirements:
According to the type of oil, impurity size, working pressure and other requirements, select the appropriate filter medium material.
Consider the corrosion resistance of the material:
Oil filters need to be exposed to oil for a long time, so corrosion resistant materials need to be selected.
Ensure the strength and stability of the material:
The filter medium and support material shall have sufficient strength to ensure the stability and service life of the oil filter.
Pay attention to the cost and availability of materials:
The cost and availability of materials are considered to reduce production costs under the premise that performance requirements are met.
To sum up, the material preparation of oil filters involves many aspects, including filter medium materials, support and sealing materials, other auxiliary materials, and material selection and precautions. When preparing materials, it is necessary to comprehensively consider the performance requirements, working environment, cost and other factors of the oil filter to ensure the quality and reliability of the final product.
