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.

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.

The viscosity of hydroxypropyl methylcellulose HPMC is inversely proportional to the temperature, that is, the viscosity increases as the temperature decreases. We usually say that the viscosity of hydroxypropyl methylcellulose HPMC refers to the test result of hydroxypropyl methylcellulose HPMC at a temperature of 20% in a 2% aqueous solution.

Especially in summer, construction is very frequent in this season, and there is a large demand for cellulose. Manufacturers must also do a good job of moisture-proof storage while mass production. When storing cellulose in summer, we should pay attention to moisture prevention,

You may be unfamiliar when it comes to hydroxypropyl methyl cellulose, but when it comes to cement, mortar, and concrete, everyone is familiar with it. Hydroxypropyl methyl cellulose is an important additive in cement, mortar, and concrete. Let’s take a look at hydroxypropyl. What are the effects of methyl cellulose on the properties of cement, mortar and concrete.

The most important characteristic of hydroxypropyl methylcellulose is its water retention capacity in building materials. Maintain sufficient water in the mortar for a long time to meet the workability, and water also plays a role of lubrication and mixing in the inorganic composition. In this way, the thin layer mortar is easy to be combed or the plaster mortar is easy to be leveled repeatedly. In addition, due to the addition of cellulose in the mortar, the wall does not need to be wetted, so it can be constructed more efficiently.
