Car 76*182*20 Board Carbon Air Filter Paper

1. Product introduction

Filter paper is a filter tool commonly found in chemical laboratories.

The common shape is round, mostly made of cotton fiber. Filter paper can generally be divided into two types: qualitative and quantitative. In the application of analytical chemistry, when the inorganic compound is filtered to separate the precipitate, the residue collected on the filter paper can be used to calculate the loss rate during the experiment. Qualitative filter paper has more cotton fibers after filtration, so it is only suitable for qualitative analysis; quantitative filter paper, especially ash-free filter paper through special processing procedures, can more effectively resist chemical reactions, so the generated There are few impurities and can be used for quantitative analysis.

In addition to the filter paper used in general laboratories, there are also many applications of filter paper in daily life and engineering. Coffee filter paper is one of the widely used filter papers, and the filter paper on the outer layer of the tea bag provides high softness and high wet strength. Other air filter papers used to test suspended particles in the air, and fiber filter papers for different industrial applications, etc.

3. Product characteristics

In order to get the ideal filtering effect, it is very important to choose high-performance filter paper. Our products have the characteristics of high filtration efficiency and long service life. Wood pulp fibers and synthetic fibers can be added to the raw materials. Attitude determines height, and establishing long-term and stable cooperative relations with customers is our unchanging principle.

4. Technology

Air filter paper is a key component of the air filter, which determines the performance of the air filter. Air filter paper usually includes a paper filter layer made of ordinary wood pulp as the main component. Because ordinary wood pulp fibers are relatively fine , Low ash capacity, short life and other shortcomings, and the paper air filter paper is not water resistant, and it is easy to deform when the air humidity changes, which will affect the filtering effect.

5. Product principle

Air filter paper is used in the air filter of automobile engine. Its function is to filter out the dust and impurities when the air enters the engine through the filter paper. Therefore, its filtering function ensures the supply of clean air and protects the engine from wear.

10. Production process

Most filter papers are made of cotton fibers and are made by different methods for different purposes. Because its material is made of fiber, its surface has countless small holes for liquid particles to pass through, while larger solid particles cannot pass. This property allows the separation of liquid and solid materials mixed together.

11. Method of operation

Hardness: The filter paper will become wet during filtration. For some long-term filtration experiments, you should consider using filter paper that is tougher after wet water.

Filtration efficiency: The density and size of the water seepage holes on the filter paper affect its filtration efficiency. The high-efficiency filter paper has fast filtration speed and high resolution.

Capacity: The solid particles accumulated during filtration may block the pores on the filter paper. Therefore, the denser the water seepage pores, the higher the capacity and the more filter that is allowed to filter.

Applicability: Some filter papers are made by special manufacturing steps. For example, they are used to determine the nitrogen content in blood in laboratory medicine. Nitrogen-free filter paper must be used.

12. Do’s and don’ts

Note that the filter paper cannot filter the zinc chloride, otherwise the filter paper will be corroded and damaged by the zinc chloride
