In addition to cement, gypsum, calcium hydroxide and dispersible latex powder, the adhesion between mortar and substrate is obtained, and cellulose ether also provides adhesion.Cellulose ether can improve the bonding strength of fresh mortar and hardened mortar. The water retention of cellulose ether in the mortar can meet the amount of water necessary for the

Daily chemical grade 200,000-viscosity hydroxypropyl methylcellulose is a white or slightly yellowish powder, and it is odorless and tasteless. It can be dissolved in cold water and organic solvents to form a transparent viscous solution. The water liquid has surface activity, high transparency, strong stability, and dissolves in water without being affected by pH. It

Redispersible latex powder used in mortar In recent years, mortar companies have added redispersible latex powder to the mortar. This is because redispersible latex powder can increase the compressive strength and flexural strength of the mortar and increase the elongation of the mortar, thereby increasing the mortar. The impact resistance of the mortar also gives

Hydroxypropyl methyl cellulose (HPMC) is a non-ionic cellulose ether made from high polymer material cellulose through a series of chemical processing. Hydroxypropyl methylcellulose (HPMC) is an odorless, tasteless, white powder that can be dissolved in cold water to form a transparent viscous solution. It has the properties of thickening, adhesion, dispersion, emulsification, film formation, suspension,

1. The pure HPMC aqueous solution of hydroxypropyl methylcellulose is clear, has high light transmittance, and the water retention rate is >95%; the adulterated HPMC aqueous solution is turbid, and the water retention rate is difficult to reach 80%. 2. Pure hydroxypropyl methylcellulose HPMC powder is fibrous under a microscope or magnifying glass; adulterated HPMC
