Ceramics

Product Description

Cellulose it is mainly used in honeycomb ceramics. Honeycomb ceramics were first used in small automobile exhaust purification, and are now widely used in chemical industry, electric power metallurgy, petroleum, electronic appliances and machinery industries. With the development of technology, more and more thin-walled honeycomb ceramic technology is used. Cellulose ether plays a very important role in the production of thin-walled honeycomb ceramics, and it has an obvious conformal effect on the blank body,for ceramics they can work as the binder that gels at elevated temperatures to improve cohesion, increase green strength, and eliminate binder migration.

They can also serve as lubricants, emulsifiers, suspending agents, and surfactants. At elevated temperatures, solutions of cellulose form a three-dimensional gel structure that gives extra stability to green ceramic bodies during drying and early stage firing. Thermal gelation also inhibits binder migration to surfaces, reducing the potential for stress cracks and blisters during firing.

Most importantly, cellulose polymers contribute remarkably plastic-like properties to ceramic mixes. With cellulose, ceramic processing so closely parallels thermoplastic processing that conventional plastics technology and equipment (i.e., extrusion and injection molding) can often be utilized with little modification. As a result, cellulose ethers present unique options for the high volume production of intricately shaped, dimensionally stable ceramic items.

Our Hecocell® cellulose ethers are used extensively across many ceramics applications ranging from bricks and tiles to pottery and bathroom appliances. The term of ceramics describes inorganic and nonmetallic basic materials. Generally they are formed from raw materials at room temperature and derive their typical characteristics through a sintering process at high temperatures. Often, these ceramic materials are called high-performance ceramics whose composition is different from a clay mineral. They are characterized by their special properties such as a high temperature resistance, high mechanical and chemical stability or low electric conductivity. Hecocell® cellulose ethers are primarily used for the chemical engineering of high-performance ceramics as process auxiliary. Depending on the application, special Hecocell® grades are used.

Hecocell® Advantages

It can improve the operability of honeycomb ceramic mold.

Honeycomb ceramic products have better blank strength.

It has good lubricity, which is conducive to extrusion molding of honeycomb ceramics and increase the qualified rate of products.

Can make honeycomb ceramic products round and delicate.

Honeycomb ceramic products can be burned with a very dense internal structure.

In honeycomb ceramics, it has an obvious role in preserving the shape of the blank, which can ensure the dimensional accuracy of the product, ensure the uniformity of the wall thickness and reduce the rejection rate.
