AB glue

The main use of AB Glue (two-component glue) of Filter Material for HEPA Filter in the HEPA Filter Line is in the bonding and sealing process of the filter.
Before the filter material is sent to the production line, a series of pre-treatment steps, such as cleaning and drying, will be carried out to ensure that the quality of the material meets the production requirements. However, this link does not usually involve the use of AB Glue. After the filter material is processed by cutting, folding and other processing steps, a preliminary filter structure will be formed. At this stage, although the filter structure has been initially formed, the final bonding and sealing may not have been carried out.
The main use of AB Glue is the bonding and sealing of the filter. This step usually occurs after the filter is formed and processed, and is used to bond and seal the filter layers, the filter and the frame, and the filter edges to ensure the integrity and sealing of the filter. AB Glue consists of two or more components, which need to be mixed evenly in a certain proportion before use. The mixed AB Glue can cure quickly and form a high-strength bonding layer, effectively preventing air leakage and pollutants from penetrating the filter.
On the production line, there are usually special equipment or workstations for mixing, coating and curing AB Glue. According to production requirements, the operator will apply an appropriate amount of AB Glue to the parts that need to be bonded, and perform appropriate compression and curing. After bonding and sealing, the filter will enter the subsequent processing and testing links, such as cleaning, performance testing after curing, etc. These steps are designed to ensure that the quality and performance of the filter meet the relevant standards and requirements.

Precautions
Due to the differences in the process flow of different manufacturers and production lines, the specific use links and operation methods of AB Glue may also be different. In actual applications, the use method and timing of AB Glue should be determined according to the specific configuration and production requirements of the production line.
The selection and use of AB Glue should strictly comply with relevant standards and specifications to ensure that the HEPA filter produced has reliable quality and performance. At the same time, operators should receive professional training and master the correct use methods and safe operating procedures to ensure the smooth progress of the production process and personnel safety.

glass fiber

The use of Glass Fiber in HEPA Filter Material for HEPA Filter in HEPA Filter Line is mainly concentrated in the preparation and molding process of the filter.

In the early stage of the HEPA filter production line, material selection and preparation will be carried out. Glass fiber is selected as one of the important materials for HEPA filter due to its excellent filtration performance, high temperature resistance and mechanical strength.
The selected glass fiber needs to consider factors such as its diameter, fiber structure and surface coating to ensure that its filtration efficiency and resistance performance meet the requirements.

Glass fiber is an inorganic non-metallic material with excellent performance, but its brittleness and poor wear resistance should be noted during use to avoid damage during processing and installation.
The preparation process of glass fiber filter requires strict control of parameters and conditions in each link to ensure that the quality and performance of the filter meet the requirements.

hotmelt

The use of Hotmelt of Filter Material for HEPA Filter in HEPA Filter Line is mainly the bonding and fixing process of the filter. Hot melt adhesive plays an important role in the production of HEPA filters due to its excellent bonding performance and environmental protection characteristics.
On the HEPA filter production line, the filter first undergoes processing steps such as cutting and folding to form a preliminary filter structure. At this time, the filter already has a basic shape and size, but further bonding and fixing are required.
Hot melt adhesive is used in this step. Hot melt adhesive is an adhesive that is solid at room temperature, becomes liquid after heating and has a certain viscosity. In the filter production process, hot melt adhesive is heated to liquid and then applied to the part that needs to be bonded.
Hot melt adhesive has the advantages of fast curing, strong bonding, and environmental protection and pollution-free. It can firmly bond the filter to the frame or other components in a short time to ensure the stability and sealing of the filter.
On the production line, there are usually special hot melt adhesive coating equipment and curing equipment. According to production requirements, the operator will apply an appropriate amount of hot melt adhesive to the contact surface between the filter and the frame, and solidify it by heating or pressurizing. After bonding and fixing, the filter will enter the subsequent processing and testing stages. These steps include cleaning, performance testing, etc., to ensure that the quality and performance of the filter meet the relevant standards and requirements.
Precautions
The selection and use of hot melt adhesive should be determined according to the specific requirements of the filter material and production process. Different types and specifications of hot melt adhesive have different performance characteristics such as adhesion, temperature resistance and curing time, and need to be carefully selected.
When using hot melt adhesive, attention should be paid to safe operating specifications to avoid accidents such as burns and fires. At the same time, parameters such as the amount of hot melt adhesive applied and the curing time should be controlled within a reasonable range to ensure bonding effect and production efficiency.
