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
The role of RDP in tile adhesives is mainly the following aspects. 1. As the amount of cement increases, the original strength of the tile adhesive increases. At the same time, the tensile adhesive strength after water immersion and thermal aging also increased. The amount of cement should be above 35%. 2. With the increase
1. Improve the compressive strength and flexural strength of mortar. 2. The addition of RDP improves the elongation of the mortar. Thereby improving the impact toughness of the mortar. At the same time, it also gives good stress dispersion effect to the mortar. 3. Improve the bonding performance of mortar. The bonding mechanism is based
This article explains how to use tile adhesive. Step 1: Wet the construction wall and ground. Walls and floors must be kept dry inside. Walls and ground surfaces need to be kept flat. Cement mortar can be used to smooth the uneven or rough surface. Step 2: Remove dust, oil and other stains on the
The basic role of dispersible polymer powder in tile adhesive 1. Redispersible latex powder improves the compressive strength and flexural strength of tile adhesive. 2. The redispersible latex powder is dispersed to form a film and act as a second adhesive to play a reinforcing role. 3. The protective colloid is absorbed by the mortar
Reuse of Dispersible Polymer Powder (RDP) in Tile Adhesive Now when there are family decoration tiles, cement stickers are used. In fact, cement is not suitable for installing tiles, and tiles bonded with cement are particularly prone to hollowing and falling off. So what's the best glue to stick tiles with? Tile glue is a
Hydroxyethyl cellulose to make water-based paint (2) 1. Add directly during production - this method is simpler and takes less time. Add directly when grinding the pigment: This method is simple and takes a short time. The detailed steps are as follows: (1) Add appropriate purified water into the large bucket of the high-shear mixer
This article mainly introduces the application of HEC in the textile industry ●Fabric sizing HEC has been used for sizing and dyeing of yarn and fabric materials for a long time. This glue can be washed away from the fiber by washing with water. In mixing with other resins, HEC can be more widely used
