Ceramics

Who gets fired up at the thought of solving a problem?

阿里彩票登陆平台 www.o1e1e.com.cn We do!
From glazes that don't drip to stronger greenware to the advanced ceramics used in catalytic converters, and environmental filters, Ashland's knowledge in traditional and advanced ceramics can help you reduce waste and increase profits.  Ashland products strengthen greenware making it less prone to breakage both before and during the firing process.  And, our rheology products help create glazes that don't run or drip keeping your ceramic designs beautiful. 

Advanced Ceramics
Manufacturers of advanced ceramics such as catalytic converters, diesel particulate filters and industrial environmental filters require ingredients that provide the right amount of plasticity and workability during the shaping and molding process, while maintaining firmness of the wet mass after extrusion and before drying (wet green strength).

During the drying process, these ingredients help ensure uniform, controlled drying and prevent the formation of cracks and blisters that can affect the performance of the converter or filter.  Although the needs are the same, different binders are used for the different manufacturing processes.  All manufacturers want to minimize costly equipment maintenence and repairs  so they are also looking for products that help reduce wear and tear on manufacturing equipment and completely burn so there is little to no residue to deal with after manufacturing. Ashland offers a variety of products that can help solve these manufacturing needs. 

Traditional Ceramics
To create beautiful ceramics, artists are looking for binder ingredients that increase the plasticity or workability of the material while providing enough strength to maintain the shape during the drying stage. Ashland products are also used as rheology modifiers to allow the glaze to go on easily without dripping or running.  These products also produce a strong, tight bond between the glaze and the ceramic body to prevent both damage to the surface prior to firing, and cracking during or after firing, which are especially important for both food and beverage applications.

Since its commercial introduction in the United States in 1946, Aqualon™ (Blanose, Bondwell) sodium carboxymethylcellulose (CMC) has found use in an ever-increasing number of applications. The many important functions provided by this polymer make it a preferred thickener, suspending aid, stabilizer, binder and film-former in a growing variety of applications. The wide range of viscosity and substitution types available for the highly purif...

Culminal™ methylcellulose (MC) derivatives help building materials apply more easily and perform better. Culminal products provide water retention, workability and cohesiveness to mixtures. They are also used to control thickening, water demand, open time, sag resistance, strength and other important properties of the final product. Culminal methylcellulose derivatives include MHEC and MHPC chemistries, mostly as formulated solutions and ta...

Natrosol™ hydroxyethylcellulose (HEC), a nonionic, water-soluble polymer, is a white, free-flowing granular powder. It is made by reacting ethylene oxide with alkali-cellulose under rigidly controlled conditions. Purified HEC for personal care and cosmetic applications is typically sold at 95.0 percent minimum purity (dry basis).  Solutions of Natrosol HEC are pseudoplastic or shear-thinning. As a result, personal care products formula...
