(1) Solubility The solubility of cellulose ether in alkaline aqueous solution, water, or organic solvent depends on the nature of the etherification group and the degree of substitution (DS). Substances with a DS value below 0.1 are generally insoluble and differ from cellulose only in some physical and technical parameters, such as tensile strength, surface […]
Dry-mixed mortar can be divided into packaged dry-mixed mortar and bulk dry-mixed mortar. The former is packed in 25kg plastic woven bags or composite kraft paper bags, while the latter is transported in bulk trucks and to steel storage tanks under pressure. Mixing of dry-mixed mortar Dry-mixed mortar should be mixed mechanically, and portable mixers […]
Wood fiber is a white or off-white powdery fiber made from high-grade natural wood rich in lignin (such as fir and beech), dietary fiber, vegetable fiber, chemically treated, extracted, and ground. Wood fiber is a natural fiber that absorbs water and is insoluble in water. It has excellent flexibility and dispersion. Adding appropriate amounts of […]
Cellulose ether is a general name for various derivatives obtained through the etherification of natural cellulose. As the primary raw material, the source, type, treatment method, and process of cellulose have a decisive impact on the synthesis and application of cellulose ether. 1. Sources and types of cellulose As early as 1838, French botanist Anselme […]
Two or more additives, sometimes as many as a dozen, are mixed into one component to become a special additive for a particular type of dry-mixed mortar to simplify the mortar process formula and reduce user inventory. This component product is usually called a composite dry mortar product additive. Composite dry-mixed mortar additives are not […]
Polymer waterproof agents refer to redispersible polymer powder, resin emulsion or water-soluble polymers. Polymer waterproof agents include various latexes, such as silicone waterproof agents, cationic chloroprene latex, natural latex, styrene-butadiene latex, and unsaturated polyester. Add stabilizer (surfactant), defoaming agent, and a certain amount of water to this type of waterproof agent, mix, and stir evenly […]
The waterproof coagulant is a liquid waterproofing agent formulated with water glass as the base material and an appropriate amount of water, copper sulfate, and potassium dichromate. It is also called a Vanadium waterproofing agent. The preparation method and quality requirements of waterproof coagulant are as follows: (1)Preparation method Heat the quantitative water to 100°C […]
The waterproof slurry is a waterproofing agent made by mixing calcium chloride, aluminum chloride, and other metal salts with water in a particular proportion. The product looks like a light yellow liquid. It can interact with cement and water after the waterproof slurry is mixed into cement mortar, it can interact with cement and water. During […]
Inorganic aluminum salt waterproofing agent is an oily liquid formed by reacting various inorganic chemicals with aluminum salt and calcium carbonate as the primary raw materials. Its color is light yellow or brownish yellow. It has complete functions of anti-leakage, anti-freeze, heat resistance, pressure resistance, early strength, and rapid setting, and is non-toxic, odorless, and […]
A Chloride metal salt water-repellent agent is a colored liquid prepared by mixing calcium chloride, aluminum chloride, and other metal salts with water in a particular proportion. After the Chloride metal salt water-repellent agent is mixed into concrete (mortar), during the hydration and hardening process of cement, it can react with cement and water to […]
