Qingdao Shuodi Environmental Protection Technology Co., Ltd. is a Chinese manufacturer specializing in the production of carboxymethyl cellulose CMC. Carboxymethylcellulose CMC is an ionic linear polymer substance, and its pure product is white or yellowish fibrous powder. Non-toxic, tasteless, easily soluble in cold water to become a transparent viscous solution, has many advantages that ordinary natural glues and synthetic rubber locks do not have, and is widely used in food processing, beverages, textiles, papermaking, oil drilling, daily chemicals, coatings , cigarettes, building materials, ceramics, mosquito coils, detergents and other industries, with unique thickeners, adhesives, emulsifiers, sizing agents, water-retaining agents, dispersants, suspending agents, expanding color-fixing agents, and retarders in Each industry plays its own role, commonly known as "industrial monosodium glutamate".
Qingdao Shuodi Environmental Protection Technology Co., Ltd. is a Chinese manufacturer specializing in the production of carboxymethyl cellulose CMC. Carboxymethyl cellulose CMC aqueous solution has the functions of thickening, film forming, bonding, water retention, colloid protection, emulsification and suspension, etc. It is widely used in petroleum, food, medicine, textile and paper making industries, and is the most important cellulose One of the ethers. When using, apply a small amount of water to infiltrate it, then add water and stir to prepare a solution with the required concentration. If other ingredients are required, it is best to mix the auxiliary materials with CMC, and gradually add them in the aqueous solution under high-speed stirring, so that they can be dissolved quickly. At the same time, attention should be paid to high temperature, and the viscosity will decrease due to the increase of temperature. Since carboxymethyl cellulose CMC is easy to absorb moisture, users should pay attention to the packaging to avoid carboxymethyl cellulose CMC products being dissolved by moisture. Carboxymethyl cellulose CMC is non-dangerous.

Carboxymethyl cellulose CMC is used in building materials as retarder, water retention agent, thickener and binder. After adding carboxymethyl cellulose CMC to the paint, it has good elasticity, air tightness and water resistance. Carboxymethyl cellulose CMC is added to the ceramic molding, and the products produced have a good appearance without cracks, defects or bubbles. In the industry of mosquito coils for CMC, carboxymethyl cellulose mainly acts as a binder to enhance the bending resistance of mosquito coils. In the paper industry, it is used for internal and external sizing and filler retention.
The inner layer of CMC white packaging is made of plastic film bags, and the outer layer is packed in composite textile bags. The net weight of each bag is 25kg or 20kg. Store in a cool, ventilated and dry place. Food-grade CMC is stored separately from other chemical raw materials. The shelf life is two years.
