How to use hydroxypropyl methylcellulose correctly in cement slurry
How to use hydroxypropyl methylcellulose correctly in cement slurry 1. The addition of HPMC has a significant retarding effect on the mortar mixture. With the increase of HPMC content, the setting time of mortar is prolonged. Under the same amount of HPMC, underwater molding mortar is better than air. Molding takes longer to set. This […]

The effect of on self-leveling mortar Relying on its own weight, self-leveling mortar forms a flat, smooth and firm foundation on the substrate, allowing other materials to be laid or bonded, while achieving large-area, high-efficiency construction. Therefore, high fluidity is a very important feature of mortar self-leveling mortar; in addition, it must have a certain […]

Precautions for the use of redispersible polymer powder The redispersible latex powder is not suitable for one-time input, and it is necessary to divide the amount in order to find a suitable amount. When polypropylene fibers need to be added, they must be dispersed in the cement first, because the fine particles of the cement […]

Anti-dispersion is an important technical indicator to measure the quality of anti-dispersant. Hydroxypropyl methylcellulose is a water-soluble polymer compound, also known as water-soluble resin or water-soluble polymer. It is a hydrophilic polymer material that is added to the viscosity of the mixture by adding the viscosity of the stirring water. It can be dissolved in […]
READ MORE...Function and application of redispersible latex powder
Redispersible latex powder is a powder binder made of special emulsion (polymer) after spray drying. This powder can be quickly redispersed to form an emulsion after contacting with water, and has the same properties as the initial emulsion, that is, a film can be formed after the water evaporates. This film has high flexibility, high […]

The Redispersible latex powder product is a water-soluble redispersible powder, which is a copolymer of ethylene and vinyl acetate, and uses polyvinyl alcohol as a protective colloid. Due to the high binding ability and unique properties of dispersible polymer powders, such as water resistance, workability and thermal insulation, their application range is extremely wide. Redispersible […]
READ MORE...The difference between hydroxypropyl methylcellulose HPMC slow-dissolving and instant products
Hydroxypropyl methyl cellulose (hereinafter referred to as HPMC) can be divided into instant type and slow-dissolving type. Instant hydroxypropyl methyl cellulose (HPMC) refers to the use of cross-linking agent to treat its surface in the production process, so that HPMC can be used in cold water. It disperses quickly in the middle of the water, […]
