As for hydroxypropyl methylcellulose, many people may not be clear about it, but it is very complicated from the name. Today I will come to help you understand this product from a few small questions. Please read it carefully.

Hydroxypropyl content and viscosity, most users are concerned about these two indicators. With high hydroxypropyl content, water retention is generally better. Large viscosity, water retention, relatively (but not absolute) is better, and high viscosity, better use in cement mortar.

In order to make better use of this product, we need to understand its related knowledge and performance. Today we will first understand how to test the viscosity of this product, please be sure Read it carefully.

Many friends who are engaged in the construction and decoration industry for the first time are very unfamiliar with these two kinds of latex powders, and even confuse them. The following mortar latex powder manufacturers will distinguish between putty powder and putty powder for you. The putty powder is pure white in appearance and is mainly used for repairing and leveling walls. There are many types according to different purposes

Hydroxypropyl methyl cellulose is a water-soluble polymer compound, also known as water-soluble resin or water-soluble polymer. It increases the consistency of the mixture by increasing the viscosity of the mixing water. It is a hydrophilic polymer material. It can be dissolved in water to form a solution or dispersion. Experiments show that when the amount of naphthalene-based superplasticizer increases, the incorporation of water-reducing agent will reduce the dispersion resistance of fresh cement mortar.

1. The role of hydroxypropyl methylcellulose in construction mortar and plastering mortar: high water retention capacity can fully hydrate the cement and significantly increase the bonding strength. At the same time, the tensile strength and shear strength can be appropriately increased, greatly improving the construction effect and improving work efficiency.

The hydroxypropyl cellulose ether hpmc is provided with a water-repellent and thickening-imparting cellulose ether.
Redispersible polymer powder increasing the tile ceramic adhesion . It Vinyl acetate/vinyl ester copolymer, lauric acid ethylene/ethylene/vinyl chloride.

Hydroxypropyl methylcellulose, also called hpmc, is used in many industries and can be used as a variety of additives. Among them, hydroxypropyl methylcellulose is most commonly used in the construction industry. It has very good performance, good water retention, thickening, and construction performance. Let us focus on the water retention of hydroxypropyl methylcellulose:

Redispersible latex powder is a powder binder made by spray-drying a special emulsion (polymer). This powder can be dispersed again into an emulsion after contact with water, and has the same properties as the original emulsion, that is, a film can be formed after the water is evaporated. This film has high flexibility, high weather resistance and a variety of High adhesion of the substrate. In addition, the water-repellent latex powder can have a good water resistance of the internal and external wall putty powder.
