Various problems may arise during dry-mix mortar construction. What are the common ones? What is the solution? Landcel will tell you. 1. Why do air bubbles appear soon after the dry-mixed mortar is plastered? 1.1 Reason analysis: 1.1.1 Mortar admixture or water-retaining thickening material has poor adaptability to cement. Causes the reaction to generate bubbles.

The tensile strength and cohesion of the polymer resin film formed by the latex powder are enhanced. due to the flexibility of the polymer. The deformation ability is much higher than that of cement stone rigid structure. The deformation properties of the mortar are improved. The effect of dispersing stress is greatly improved. Thereby improving

The process of polymer film formation is divided into three stages. In the first stage, the polymer particles move freely in the form of Brownian motion in the initial emulsion. As the water evaporates, the movement of the particles is naturally more and more restricted. The interfacial tension between water and air causes them to

Redispersible polymer powder and other inorganic adhesives (such as cement, slaked lime, gypsum, clay, etc.), as well as various aggregates, fillers, other additives (such as hydroxypropyl methylcellulose, polysaccharide (starch ether), Cellulose fibers, etc.) are physically mixed to make dry-mixed mortar. When the dry powder mortar is added to the water and stirred. Under the action

Analysis of the importance of HPMC for dry mix mortar(Ⅰ) Analysis of the importance of HPMC for dry mix mortar(Ⅱ) Generally speaking, the higher the viscosity, the better the water retention effect. However, the higher the viscosity, the higher the molecular weight of MC, and its solubility will be reduced accordingly, which has a negative

HPMC Chinese name hydroxypropyl methyl cellulose, non-ionic, is often used as a water retention agent in dry-mixed mortar. And it is the most commonly used water retention material in mortar. HPMC production process is mainly cotton fiber (domestic) through alkylation, etherification and generated a polysaccharide-based ether products. It is not charged itself and does not

What role does cellulose ether play in dry mix mortar?

Let's talk cellulose ether in dry mix mortar. Cellulose ether is a synthetic polymer made of natural cellulose as raw material by chemical modification. Cellulose ether is a derivative of natural cellulose, cellulose ether production and synthetic polymers are different. Its basic material is cellulose, a natural polymer compound. Due to the particularity of natural
