Factors affecting the viscosity of PVC paste resin

​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.

The mechanism of action of water reducer

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.

Several preliminary identification methods for Vae Redispersible Powder for Building Material

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.

Properties of Polycarboxylic Superplasticizer

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.

The role of cellulose ether in dry mixed mortar!

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.

Study on the interaction mechanism between polycarboxylic acid and naphthalene-based water reducing agent

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.

Application of lithium silicate in coatings

is a compound formed by the structure and formation of metallic lithium and silicate radicals. The trade name is lithium water glass. Most of them use the lithium hydroxide method to react sodium silicate with sulfuric acid to generate hydrated silicic acid and sodium sulfate. The hydrated silicic acid reacts with lithium hydroxide to generate lithium silicate and water to prepare lithium silicate products.
