Carbon brick raw materials include anthracite, coke and graphite, as well as asphalt, tar and anthracene oil binder. Anthracite has less volatile matter and dense structure, so it is often used as aggregate in the production of carbon brick. Adding metallurgical coke, asphalt as binder




Products Application :
1. Phosphoric acid reaction tank

2. Lining of phosphoric acid scrubber

3. Phosphoric acid and hydrochloric acid, hydrofluoric acid, storage tank lining

4. Power plant desulfurization tower and chimney lining

5. Stainless steel pickling line
 

6. lithium production, and the manufacturer supporting anti-corrosion equipment

The impregnated graphite carbon plate and graphite carbon brick produced by the company are made of high-quality graphite carbon materials and added with organic compound with strong acid resistance. It is refined by high pressure molding, vacuum impregnation and high temperature heat treatment process. It has excellent acid and temperature resistance. It is an ideal lining material for phosphoric acid reaction tank and phosphoric acid storage tank in chemical industry.

The company impregnated graphite carbon plate, graphite brick has the following characteristics:

1. Excellent corrosion resistance
The products are made of excellent graphite carbon materials and organic compound with strong acid resistance, which can effectively reduce the porosity of the products and improve the bulk density of the products. Therefore, the products have excellent anti-corrosion performance and relatively strong wear resistance.

2. Stable performance and strong durability
The product uses high-strength organic adhesive as binder, and introduces high-tech additives, so the product has high strength, good wear resistance, extremely stable structure, and the product structure does not change with the change of temperature

3. Accurate dimensions
The molding is adopted, the product is of good quality and accurate shape and size. It can produce special products according to the requirements of customers, and can fully meet the requirements of construction and masonry technology.
