Production of cellulose fiber

Polyanionic Cellulose is a polymer derivative of Cellulose with a high degree of purity. It is regarded as a premium product because of its typical higher carboxymethyl substitution and the presence of less residual NaCl than that of technical-grade Carboxymethylcellulose (CMC). However, PAC still contains a considerable amount of NaCl. It is a water-based drilling fluid used for varying purposes in fluid environments. Its molecular structure is similar to that of CMC, but it is considered to be better than CMC. It also has low water loss properties.

Special FTJ filter fleeces are particularly suitable as precoat or support fleece on horizontal plate pressure filters or plate filters The following precoat agents are used: Diatomaceous earth Bleaching earth Cellulose Cornmeal The FTJ nonwovens Cora®Dot and Cora®Spun effect corresponding savings on precoat agents with extremely fine filtration.

Hydroxyethyl cellulose (HEC) polymer is a hydroxyethyl ether of cellulose, obtained by treating cellulose with Sodium Hydroxide and reacting with ethylene oxide. HEC polymers are largely used as water-binder and thickening agent in many industry applications, that is, personal care products, pharmaceutical formulations, building materials, adhesives, etc., and as stabilizer for liquid soaps. They are available as white free-flowing granular powders that easily dissolve in cold and hot water to give transparent solutions with varying viscosities depending on polymer concentration, type and temperature.
