Application of diatomite

Most consumers don't know what diatomite is? What is diatomite for? How can it have such a big effect? Today, with these questions, we will reveal the secret of diatomite. Diatomite is mainly used as filter aid, filler, adsorbent, catalytic carrier, environmental protection building materials and so on.

1. Filter aid

The important use of diatomite is as filter aid. Its main application fields include beer industry, pharmaceutical industry, water purification and filtration, oil industry, mailing solution, coating and dye, fertilizer, acid, alkali, seasoning, sugar, alcohol and so on.

Diatomite filter aid can be divided into dry product, roasted product and melting roasted product according to the production process. Due to the different processing conditions, the particle size of the dried products is relatively fine, the filtration rate is the lowest, but the filtration quality is high; the roasted products are in the middle; the particle size of the roasted products is relatively coarse, the filtration rate is fast, but the filtration quality is poor. At present, the amount of dry products is very small, mainly using roasted products and melting roasted products

2. Filler

The second major use of diatomite is as functional filler, mainly used in coatings, plastics, rubber, medicine, papermaking, abrasives, precision castings and microporous ceramics. Diatomite as filler can improve the stability, elasticity and dispersion of the product, and improve the strength, wear resistance and acid resistance of the product.

Using diatomite as filler to produce paperboard can save 20% pulp, which not only reduces the production cost, but also improves the cleanliness and strength of paperboard.

Add high quality diatomite to automobile brake linings and asbestos friction linings for mechanical industry. It is easy to combine with resin and other materials, and has special binding property with rubber oil. It has filling function and reinforcing function, and can overcome the heat fading performance of products and enhance the adaptability of products.

3. Adsorbent

Diatomite adsorption is mainly physical adsorption, with fast adsorption rate and strong adsorption capacity. It is mainly used for urban wastewater, papermaking wastewater, printing and dyeing wastewater, slaughtering wastewater, oily wastewater and heavy metal wastewater. The application of diatomite as adsorbent is similar to that of filter aid. When it is used in food adsorption refining, it is required to meet the hygienic standard

4. Atalytic carrier

Because of the strong adsorption capacity of diatomite, the antibacterial solution is absorbed into the micropores of diatomite and released slowly, so it becomes a long-term antibacterial agent.

5. Environmental protection building materials

In the 21st century, people pay more and more attention to environmental protection. This kind of environmental protection consciousness is not only reflected in the natural environment, but also in the living room. In order to meet the needs of people, diatom mud ecological wall material came into being. Diatomite is an excellent material for diatomite ecological wall material because of its special structure. When the indoor humidity rises, the micropores on the diatomite wall can automatically absorb the moisture in the air and store it. If the moisture in the indoor air decreases and the humidity decreases, the diatomite wall material can release the moisture stored in the ultra-fine pores. Secondly, diatom mud ecological wall material also has the function of eliminating peculiar smell and keeping indoor clean. If the moisture in the indoor air decreases and the humidity decreases, the diatomite wall material can release the moisture stored in the ultra-fine pores. Secondly, diatom mud ecological wall material also has the function of eliminating peculiar smell and keeping indoor clean.When used at home and hotel bathroom, It can remove hydrogen sulfide and ammonia, kill harmful bacteria and prevent the spread of diseases. When used in the car interior, it can remove the harmful gas emitted by the car interior decoration products, as well as the smell of body odor, oil, smoke or vomiting due to carsickness.

With the improvement of living standards, people are more and more concerned about the living environment. Diatomite has great potential in this aspect. In the aspect of environmental pollution control, the application technology of diatomite membrane has also been widely concerned in recent years. A variety of diatomite separation membranes have been developed one after another, and the diatomite purification technology is becoming more and more perfect. Now it is important to actively apply it in environmental protection.
