In modern construction projects, concrete is a widely used building material, and its performance directly affects the quality and durability of the project. With the advancement of science and technology, the research and development of concrete additives has become a key way to improve the performance of concrete. Among them, HPEG Polycarboxylate superplasticizer monomer has become a major innovative breakthrough in the field of concrete technology in recent years with its excellent water-reducing performance and the characteristics of improving concrete workability.
Polycarboxylate superplasticizer is a new generation friendly environmental superplasticizer. It is a concentrated product, best high water reduction, high slump retention ability, low alkali content for the product, and it having high strength gained rate.It can be widely used in premix of common concrete, gushing concrete, high strength and durability concrete. Especially! It can be used in high strength and durability concrete having excellent capability .
Cement mortar: hpmc improve the dispersion of cement sand, greatly improve the plasticity and water retention of mortar, have an effect on preventing cracks and enhance the strength of cement.
PVC paste resin is widely used in artificial leather, wallpaper, floor leather, canvas coating, battery separator, industrial conveyor belt, boots, gloves, toys and other fields. PVC paste resin is generally processed in the form of plasticized paste. The molding methods include dip molding, coating, slush molding and spraying. The viscosity of the plasticized paste under specific conditions is usually used to evaluate the processing performance of the paste.
Under the condition that the slump of concrete is basically the same, the admixture of mixing water can be reduced. According to the size of its water-reducing rate, it can be divided into ordinary water-reducing agent, high-efficiency water-reducing agent and high-performance water-reducing agent.
VAE Re-dispersible Polymer Powder , as a powder adhesive, is widely used in the construction industry. The quality of dispersible latex powder is directly related to the quality and progress of construction. With the rapid development of the domestic building energy-saving market With the development of VAE Re-dispersible Polymer Powder products, more and more companies have entered into the research and development and production of VAE Re-dispersible Polymer Powder products, and users have more and more choices. However, at the same time, the quality of dispersible latex powder has become mixed, with good and bad mixed. In addition, in order to reduce costs, some manufacturers ignore quality standards and pass off inferior products as high-quality products. Some even pass off fake products as genuine, using general resin powder and selling it at low prices under the guise of redispersible latex powder. This not only disrupts the market but also deceives the market. consumer.
The common description of the performance of Polycarboxylic Superplasticizer is: high water reduction rate, very good adaptability to cement, good workability of concrete, no loss of slump in one hour, etc. In fact, the composition of cementitious materials is complex and changeable. From the perspective of adsorption dispersion mechanism, any admixture can not adapt to all situations.
From June 19th to 20th, the 37th International Fine and Specialty Chemicals Exhibition was held at the Düsseldorf Exhibition Center in Germany, attracting representatives from the global chemical and materials industries. As a company focusing on chemicals and materials, East Chemicals showcased its unique solutions at the exhibition with high-performance chemicals and advanced materials as its main line.
Hydroxypropyl methyl cellulose is a synthetic polymer made from natural cellulose through chemical modification. Cellulose ether is a derivative of natural cellulose. The production of cellulose ether is different from synthetic polymers. Its most basic material is cellulose, a natural polymer compound. Due to the special structure of natural cellulose, cellulose itself has no ability to react with etherifying agents. However, after treatment with the swelling agent, the strong hydrogen bonds between and within the molecular chains are destroyed, and the active release of the hydroxyl group becomes alkali cellulose with the ability to react. After the reaction of the etherifying agent, the -OH group is converted into the -OR group. Cellulose ether is obtained.
Polycarboxylate water-reducing agents has the properties of high water reduction and high slump retention, and can impart high strength and durability to concrete. It has shown outstanding advantages in high-quality projects such as national large-scale water conservancy, nuclear power, and bridges. Compared with naphthalene-based water-reducing agents, polycarboxylate water-reducing agents are sensitive to the mud content of sand and gravel aggregates [1-3] and are expensive. Therefore, in laboratories and engineering construction, attempts have been made to mix polycarboxylate water-reducing agents and naphthalene-based water-reducing agents to take advantage of their respective advantages.
