The difference between biochemical cotton and filter cotton

Biochemical cotton and filter cotton are two completely different things, and their uses are also different. Biochemical cotton has a wider range of uses. It can remove impurities in the water. It has a large area and is not easily damaged. It can also filter well and improve the quality of water. Filter cotton is more suitable for coating, is resistant to breakage, has a long service life, and also has a certain filtering effect.

Biochemical cotton and introduction

Biochemical cotton is a widely used filter material, which mainly plays the role of biochemical filtration. Suitable for ornamental aquariums such as saltwater tanks, freshwater tanks and aquatic plant tanks. It is mainly used to cultivate nitrifying bacteria, allowing them to decompose toxic NH3/NH4 and NO2 in water and convert them into non-toxic NO3. Therefore, it can improve water quality and increase the survival rate of fish. It is a filter material that has both physical and biochemical filtration effects. It has good elasticity, a large surface area, is not easily damaged, and can effectively filter debris in the water.

Biochemical cotton ingredients: polyether, polyester

Related differences

Biochemical cotton is not easy to clog and mainly cultivates nitrifying bacteria to decompose toxins in the water. The filter cotton mainly filters fish feces and food residues. It is easy to get clogged and needs to be washed frequently. If both are used at the same time, water is generally allowed to flow through the filter cotton first and then the biochemical cotton.

Filter cotton product performance

1. 100% relative humidity resistance;

2. Comply with European fire classification standards;

3. Application: assembly workshop, paint spraying and baking workshop, surface finishing, baking room, etc.

Filter cotton products are generally used in the surface coating industry and are specially designed for end-of-line filtration in spray booths. They are made of high-performance hot-melt non-woven fabrics composed of break-resistant synthetic fibers. They adopt an incremental structure, that is, the fiber density gradually increases toward the direction of pure air, the filtration efficiency also increases, and the service life is longer.

Production process

After being opened, mixed and combed, the web is evenly formed, and then hot-melted and cooled to form sheets or rolls. Then it goes through post-processing (such as gluing, laminating with cloth (net), etc.), and finally drying and shaping to produce the air filter cotton, also called hot air cotton. It can resist the influence of chemical substances such as chemical solvents and acidic fumes; the incremental structure uses gradually denser multi-layer technology to block dust at different density levels according to the size of the dust, and can more effectively accommodate more dust; it has the characteristics of high dust holding capacity and low resistance, and can be used many times after vacuuming or cleaning.

Process

Blending - opening - secondary opening - blending box - carding - laying net - hot air setting - cooling - trimming and curling

1. Blending: According to different requirements of customers, fiber cotton is mixed in different proportions. After weighing the initial weight, it is poured into the mixer and stirred by the machine to mix all the raw materials evenly.
