Effect of latex powder on the flexibility of mortar
The admixture has a good effect on improving the performance of construction dry-mixed mortar, and the redispersible rubber powder is made of a special polymer emulsion after spray drying. The dried rubber powder is some spherical particles of 80~100mm gathered together. These particles are solub...Read more -
The positive effect of polymer powder on the durability of mortar
At present, redispersible latex powder has played an important role as an additive of construction mortar. Adding redispersible latex powder into the mortar can prepare a variety of mortar products such as tile adhesive, thermal insulation mortar, self-leveling mortar, putty, plastering mortar, d...Read more -

Abstract: Cellulose ether is the main additive in ready-mixed mortar. The types and structural characteristics of cellulose ether are introduced, and hydroxypropyl methylcellulose ether (HPMC) is selected as the additive to systematically study the influence on various properties of mortar. . Stu...Read more -
Preparation of hemp stalk cellulose ether size and its application in sizing
Abstract: In order to replace the non-degradable polyvinyl alcohol (PVA) slurry, hemp stalk cellulose ether-hydroxypropyl methylcellulose was prepared from agricultural waste hemp stalks, and mixed with specific starch to prepare the slurry. Polyester-cotton blended yarn T/C65/35 14.7 tex was siz...Read more -
How do ready-mixed mortar additives improve mortar performance?
Modified additives such as ready-mixed mortar additives, cellulose ether, coagulation regulator, redispersible latex powder, air-entraining agent, early strength agent, water reducer and other modified additives are added according to the needs of the project, which greatly improves the performan...Read more -
Mechanism of action of methyl cellulose ether
In the composition of dry powder mortar, methyl cellulose is a relatively low addition amount, but it has an important additive that can significantly improve the mixing and construction performance of mortar. To put it simply, almost all the wet mixing properties of mortar that can be seen with ...Read more -
What is the etherification synthesis principle of hydroxypropyl methylcellulose?
Hydroxypropyl methylcellulose is used as a raw material substrate to produce oil, which can realize the utilization of total sugar, improve the utilization rate of raw materials, reduce the residual amount of substrate in the fermentation broth, and reduce the cost of wastewater treatment. This h...Read more -
Synthesis and Characterization of Butane Sulfonate Cellulose Ether Water Reducer
Synthesis and Characterization of Butane Sulfonate Cellulose Ether Water Reducer Microcrystalline cellulose (MCC) with a definite degree of polymerization obtained by acid hydrolysis of cellulose cotton pulp was used as raw material. Under the activation of sodium hydroxide, it was reacted with 1...Read more -
What are the selection methods of dry-mixed mortar additive cellulose ether?
One of the biggest differences between dry-mixed mortar and traditional mortar is that the dry-mixed mortar is modified with a small amount of chemical additives. Adding one additive to dry powder mortar is called primary modification, adding two or more additives is called secondary modification...Read more -
Effect of latex powder on the performance of EPS thermal insulation mortar
EPS granular thermal insulation mortar is a lightweight thermal insulation material mixed with inorganic binders, organic binders, admixtures, additives and light aggregates in a certain proportion. Among the EPS granular thermal insulation mortars currently researched and applied, it can be recy...Read more -
Function and application of cellulose ether in ready-mixed mortar
Cellulose ether mainly has the following three functions: 1) It can thicken the fresh mortar to prevent segregation and obtain a uniform plastic body; 2) It has an air-entraining effect, and can also stabilize the uniform and fine air bubbles introduced into the mortar; 3) As a water-retaining ag...Read more -
Methyl cellulose ether on room temperature curing ultra-high performance concrete
