Effect of Hydroxypropyl Methyl Cellulose Ether (HPMC) on the Water Holding Capacity of Powder
Hydroxypropyl methylcellulose (HPMC) mainly plays the role of water retention, thickening and improving construction performance in cement, gypsum and other powder materials. Excellent water retention performance can effectively prevent the powder from drying and cracking due to excessive water l...Read more -
Application example of CMC in acidic milk drink
1. Theoretical basis It can be seen from the structural formula that the hydrogen (Na+) on CMC is very easy to dissociate in aqueous solution (generally exists in the form of sodium salt), so CMC exists in the form of anion in aqueous solution, that is, it has a negative charge and is amphoteric....Read more -
Sodium carboxymethyl cellulose (CMC) as a food thickener
Sodium carboxymethyl cellulose (also known as: sodium carboxymethyl cellulose, carboxymethyl cellulose, CMC, Carboxymethyl, Cellulose Sodium, Sodium salt of Caboxy Methyl Cellulose) is the most widely used and the largest amount used in the world today types of cellulose. CMC-Na for short, is a c...Read more -
Classification of Cellulose
01 Hydroxypropyl Methyl cellulose 1. Cement mortar: Improve the dispersion of cement-sand, greatly improve the plasticity and water retention of mortar, have an effect on preventing cracks, and enhance the strength of cement. 2. Tile cement: improve the plasticity and water retention of pressed t...Read more -
Hydroxypropyl methyl cellulose, do you know?
1.HPMC is divided into instant type and fast dispersion type. The HPMC fast dispersion type is suffixed with the letter S, and glyoxal must be added during the production process. HPMC instant type does not add any letters, such as “100000″ means “100000 viscosity. 2. With or wi...Read more -
How is the trend of Cellulose ether?
Cellulose ether is made from cellulose through the etherification reaction of one or several etherification agents and dry grinding. According to the different chemical structures of ether substituents, cellulose ethers can be divided into anionic, cationic and nonionic ethers. Ionic cellulose et...Read more -
The role of HPMC in wet mortar
1.Wet mixed mortar: mixed mortar is a kind of cement, fine aggregate, admixture and water, and according to the properties of various components, according to a certain ratio, after being measured at the mixing station, mixed, transported to the location where the truck is used, and entered into ...Read more -
Quality Identification of Hydroxypropyl Methyl Cellulose
one. The difference between adulterated hydroxypropyl methylcellulose (HPMC) and pure hydroxypropyl methylcellulose (HPMC) 1. Appearance: Pure hydroxypropyl methylcellulose HPMC looks fluffy and has a low bulk density, ranging from 0.3-0.4g/ml; adulterated hydroxypropyl methylcellulose HPMC has ...Read more -

Characteristics and Applications of Hydroxyethyl Methyl Cellulose HEMC
The main characteristics of hydroxyethyl methyl cellulose (HEMC) are: 1. Solubility: soluble in water and some organic solvents, HEMC can be dissolved in cold water, its maximum concentration is only determined by viscosity, solubility varies with viscosity, the lower the viscosity, the greater t...Read more -
Tile Adhesive Construction
There are two kinds of materials commonly used for laying tiles: one is tile adhesive, and the other is the auxiliary paste material tile adhesive, which can also be called tile back glue. The tile adhesive itself is an emulsion-like auxiliary material, so how do we use the tile adhesive correctl...Read more -
How to use tile adhesive correctly
Clean the back of the tile first. If the stains, floating layer and residual release powder on the back of the tiles are not cleaned up, it is easy to gather and fail to form a film after the adhesive is applied. Special reminder, the cleaned tiles can only be painted with adhesive after they are...Read more
