Effect of polycarboxylate superplasticizer on self-leveling performance

Due to the low softening point of ordinary polycarboxylate superplasticizers, they cannot be powdered by ordinary spray drying methods. Only by increasing the softening point through molecular design without basically losing water-reducing performance can we obtain powdered polymers with higher effective ingredients. Carboxylic acid water-reducing agent, while ordinary polycarboxylic acid water-reducing agent can only be powdered by adding an appropriate amount of carrier, and the relative active ingredient content is low. Let’s take PC2 (effective ingredient content 90%) and PC1 (active ingredient content 30%) two types of polycarboxylate water-reducing agents as representatives to look at the impact of water-reducing agents on self-leveling mortar.

Use of HPMC in the construction industry

HPMC, or Hydroxypropyl Methylcellulose, is a versatile chemical compound that is widely used in the construction industry. It is a type of cellulose ether that is derived from natural cellulose and is a water-soluble polymer. HPMC is used in various applications in the construction industry, including:

Problems in the practical application of polycarboxylate superplasticizer in concrete engineering

Effect of water consumption on performance of polycarboxylic acid water reducer The influence of water consumption of polycarboxylic acid water reducer is very obvious. In the practical application of concrete engineering, sometimes if the water consumption increases by 1~3kg/m3, the concrete will show serious bleeding, resulting in pitting, sanding, holes and other defects on the concrete surface. The uniformity of concrete pouring and construction quality cannot be guaranteed, resulting in the reduction of the strength and durability of the concrete structure.

Innovative applications of lithium carbonate in the construction industry

With the continuous advancement of science and technology and the improvement of environmental protection requirements, the inorganic salt material - Lithium carbonates, plays an increasingly important role in the construction industry because of its unique physical and chemical properties. From improving the performance of building materials to enhancing the level of building intelligence, the application of lithium carbonate is gradually becoming a key factor in promoting industry innovation and sustainable development.

HPEG polycarboxylate water-reducing agent monomer: an innovative breakthrough in concrete technology

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.

Take you to know Polycarboxylate superplasticizer

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 .

What is the water reduction rate of polycarboxylate ether superplasticizer

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.

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.
