In addition to ventilation, the most important function of the fresh air system is to filter pollutants in the air. Therefore, the filter of the fresh air system is the most important part of the entire system. Let’s take a look at the three layers and five layers. layer of high-efficiency filter paper.
High-efficiency filters are key components of the air cleaning system. Currently, the filter materials used in China are ultra-fine glass fiber paper and ultra-fine asbestos fiber paper, which are used to filter the particles that cannot be filtered by coarse and medium-efficiency filters and whose content is up to 1 μm. The following industrial micron-level particles ensure the cleanliness requirements of clean rooms.
In order to ensure the filtration efficiency of the filter and the cleaning effect of the clean system, the installation of high-efficiency filters must comply with the requirements of the “Clean Room Construction and Acceptance Specifications” or design drawings.
At present, there are two methods of laminating three-layer and five-layer high-efficiency filter paper: glue lamination and thermal lamination.
1. Glue lamination is a relatively basic lamination method, which has low composite strength, is easy to peel off, and has a short service life. Due to the penetration of glue, it has poor air permeability and is not suitable for dust cleaning, which weakens the superior performance of PTFE.
2. Thermal lamination advanced lamination method completely maintains the superior performance of polytetrafluoroethylene film, but has strict requirements for thermal lamination technology.
It is a three-layer and five-layer high-efficiency filter paper manufacturer that specializes in R&D, production and sales.
Our company is different from other manufacturers.
