3. Application
Oil drilling Industry
Oil drilling grade CMC used in fracturing fluid, drilling fluid and well cementing fluid as fluid loss controller and tackifier. It can protect the shaft wall and prevent mud loss thus enhance recovery efficiency.
Construction Industry
Used as the water retaining agent and retarder in mortar to make it has good pumpability.
Used as adhesives in plaster, gypsum material, putty powder or other construction materials to improve its workability and extend the operation time.
Textile, Printing, Dyeing Industry
Used in textile, printing and dyeing industry textile industry will CMC as sizing agent, used for cotton, silk, chemical fiber, blending and strong fine gauze sizing.
Papermaking Industry
Used in the papermaking industry CMC in paper industry for paper smoothing agent, sizing agent. Add 0.1% ~ 0.3% of CMC in pulp can make paper strength 40% ~ 50% resistance to tension, compression fracture degree is increased by 50%, and increase 4 ~ 5 times.
Food Industry
Used in the food industry, food industry high substitution degree of CMC for ice cream, canned beer, on the surface of the instant thickening agent, foam stabilizer, etc., in the process of jam, sugar juice, fruit, dessert, ice cream beverages as a thickener, binder, or due to the agent.
