Hydroxypropyl methylcellulose is one of the important cellulose ether additives in the dry mortar, and it has many functions in the mortar. The main function of hydroxypropyl methylcellulose in cement mortar is water retention and thickening. In addition, due to its interaction with the cement system, it can also play a role in air entrainment, […]

In the ready-mixed spray mortar, the addition amount of hydroxypropyl methyl cellulose ether is very low, but it can significantly improve the performance of wet mortar and is a major additive that affects the construction performance of mortar. Reasonable selection of cellulose ethers of different varieties, different viscosities, different particle sizes, different viscosity degrees and […]

The performance of hydroxyethyl methyl cellulose 30011C in tile adhesive: good anti-sag effect, long open time, high early strength, high temperature adaptability, easy to stir, easy to operate, non-stick knife, etc. Product nature Water solubility and thickening ability: This product can be dissolved in cold water to form a transparent viscous solution. Soluble in organic […]

Hydroxypropyl methylcellulose, also known as HPMC, is a non-ionic cellulose ether obtained by a series of chemical processing with natural polymer material refined cotton as raw material. It is a white or slightly yellowish powder, easily soluble in water. Let’s talk about the dissolving method of hydroxypropyl methylcellulose. Tools/Materials Hydroxypropylmethylcellulose water method/step First of all, […]

What is the difference between hydroxypropyl methylcellulose (HPMC) with or without S? 1. HPMC is divided into instant type and rapid dispersion type HPMC fast dispersing type is suffixed with the letter S. During the production process, glyoxal should be added. HPMC instant type does not add any letters, such as “100000” is “100000 viscosity […]

Hydroxypropyl methylcellulose can be used in toothpaste, shampoo, shower gel, hand sanitizer and shoe polish daily chemical products in the field of daily chemicals, and has the effect of thickening and preventing sedimentation. Similar products to hydroxypropyl methyl cellulose HPMC include hydroxymethyl cellulose CMC, ethyl cellulose EC, hydroxypropyl cellulose HPC, methyl hydroxyethyl cellulose MHEC, methyl […]

A friend asked why hydroxypropyl methylcellulose sometimes smells, is it a quality problem? Before answering this question, let’s take a look at the production process of hydroxypropyl methylcellulose. Hydroxypropyl methyl cellulose, also known as hypromellose, cellulose hydroxypropyl methyl ether, is obtained by selecting highly pure cotton cellulose as raw material and specially etherified under alkaline […]

1. Whiteness: Of course, the decisive factor that determines the quality of hydroxypropyl methylcellulose cannot be whiteness. Some manufacturers cannot judge the quality of hydroxypropyl methylcellulose when they add whitening agents in the production process, but high-quality hydroxypropyl methylcellulose The base cellulose whiteness is indeed good. 2. Fineness: The fineness of hydroxypropyl methylcellulose is generally […]

1. This method is suitable for determining the dynamic viscosity of non-Newtonian fluids (polymer solutions, suspensions, emulsion dispersion liquids or surfactant solutions, etc.). 2. Instruments and utensils 2.1 Rotational viscometers (NDJ-1 and NDJ-4 are prescribed by the Chinese Pharmacopoeia) Viscometers (such as NDJ-1 and NDJ-4) that use frequency stabilization measures must be spared. Accuracy 1% […]

Diatom mud is a kind of interior decoration wall material with diatomite as the main raw material. It has the functions of eliminating formaldehyde, purifying the air, adjusting humidity, releasing negative oxygen ions, fire retardant, wall self-cleaning, sterilization and deodorization. Because diatom mud is healthy and environmentally friendly, it is not only very decorative, but […]
