Advantages and welding methods of EPPL polypropylene pleated filter element

EPPL electronic grade polypropylene pleated filter element is a product specially manufactured for the electronic industry and electronic chemicals. It has many significant advantages, as follows:

1.High-efficiency filtration: The filter element is made of a new generation of polypropylene material by hot-melt welding, which ensures high porosity and high surface area, and can meet the stringent high-efficiency filtration requirements during processing.

2.High flow rate: Compared with ordinary filter materials, this filter element has a 20% higher flow rate, while improving the impurity removal efficiency of the product, and the β value can reach 500.

3.Low pressure difference: The filter membrane is not affected by feed pressure fluctuations and can maintain a stable filtration accuracy. The filter element has the characteristics of low pressure difference, which is conducive to reducing energy consumption.

4.Long service life: The filter element skeleton is made of high-strength polypropylene material, which can support backwashing applications, thereby extending the service life and reducing maintenance and operating costs.

5.Good chemical compatibility: The filter element is completely non-toxic and pollution-free, meeting FDA requirements, indicating that it has good chemical compatibility and is suitable for a variety of chemical environments.

6.Wide range of applications: The filter element has a filtration accuracy range from 0.1μm to 60μm, which can meet the needs of liquid filtration in industries such as food and beverage, drinking water, reverse osmosis water in the electronics industry, deionized water pre-filtration, biopharmaceuticals, cosmetics research and development, and other fine chemicals.

EPPL electronic grade polypropylene folded filter element has been widely used and recognized in many fields due to its significant advantages such as high-efficiency filtration, high flow rate, low pressure difference, long service life and good chemical compatibility.

Welding method: pulse heat sealing connection

Principle: The heat generated by high-frequency pulse current is used to melt and tightly bond the polypropylene material between the end cover of the filter element and the filter element body.

Features:

The welding process is fast and the connection operation can be completed in a short time.

The welding strength is high and the sealing is good, which can ensure that the filter element does not leak or fall off during use.

No adhesive is required, avoiding possible contamination problems.

Welding precautions

1.Preparation before welding: Ensure that the welding part of the filter element is clean and free of impurities to improve the welding quality.

2.Welding parameter control: According to the material, thickness and welding requirements of the filter element, select appropriate welding temperature, time and pressure and other parameters.

3.Welding process monitoring: During the welding process, it is necessary to monitor the welding quality in real time to ensure that the welding part is fully melted and tightly bonded.

4.Post-welding inspection: Perform quality inspection on the filter element after welding to ensure that there are no cracks, leaks and other problems in the welding part.
