When we hear about hydroxypropyl methyl cellulose, many of us must feel very unfamiliar. Hydroxypropyl methyl cellulose is a semi-synthetic, inactive, viscoelastic polymer, often used in ophthalmology as a lubricant. , Or as an excipient or excipient in oral medicine

Ordinary concrete is silicate. In the case of air or water vapor, silicate ions will undergo a hydrolysis reaction, and the generated hydroxyl groups and metal ions will combine to form hydroxides with less solubility (alkaline chemical properties).

1. Hydroxypropyl methyl cellulose HPMC has stable chemical properties, mildew-proof and water-retaining effects in the glue, and is not affected by changes in pH. The viscosity can be used from 100,000 S to 200,000 S. However,

Bonding mortar: to ensure that the cement mortar will bond the wall and the epoxy wallboard with strong adhesion. Improve the bonding compressive strength.

Plastering mortar: to ensure the impact toughness, crack resistance and impact resistance of the system.

1) Putty powder, tile adhesive, caulking agent, bonding mortar, plastering mortar, etc. can be used up to 100,000 viscosity hydroxypropyl methylcellulose.

The effect and application of hydroxypropyl cellulose ether in building materials. In most cities in China, the environmentally friendly putty that is resistant to water and wiping has been paid attention to. In the past few years, putty made of building glue emits formaldehyde gas hazards.

Enhance the adhesion to the surface of the masonry, and can enhance the water retention, so that the strength of the mortar can be improved. Improve lubricity and plasticity to improve construction performance, easier to apply, save time, and improve cost-effectiveness.

1. Appearance method: Use a glass rod to thinly and evenly cover a small amount of redispersible latex powder on the surface of a clean glass plate. The redispersible latex powder manufacturer places the glass plate on white paper and inspects the particles visually. The appearance of foreign matter and coagulum.

Accurate weighing and measurement of hydroxypropyl methyl cellulose samples, hydroxypropyl methyl cellulose cover the crucible half, calculate the content of iron salt content: the amount of plastic iron is 1000, the sample quality is measured several times and transferred to 50mL Volumetric flask to remove iron; accurately weigh 1～1.5g (accurate to 0.0001g) sample
