Audited Supplier HPMC is a water-soluble polymer compound, also known as water-soluble resin or water-soluble polymer. It is a hydrophilic polymer material that increases the consistency of the mixture by increasing the viscosity of the mixed water . Water can dissolve to form a solution or dispersion.
Cement mortar is an indispensable material in construction.
Experiments show that when the amount of naphthalene-based superplasticizer is increased, the addition of superplasticizer will reduce the dispersibility of fresh cement mortar. This is because the naphthalene-based superplasticizer is a surfactant. When the water reducing agent is added to the mortar, the water redcing agent is oriented on the surface of the cement particles so that the surface of the cement particles has the same charge, and the electric repulsion causes the cement particles to form. The flocculation structure is disassembled, and the water in the structure is released, causing part of the loss of cement. At the same time, it was found that as the HPMC content increases, the dispersion resistance of cement mortar becomes better and better.
Hydroxypropyl MethylCellulose (HPMC) are widely used in construction, pharmaceutical,food, cosmetic, detergent, paints, as thickener, emulsifier, film-former, binder, dispersing agent, protective colloids.
HPMC-Hydroxypropyl Methyl Cellulose and Methyl Hydroxyethyl Cellulose and non-ionic cellulose ether made by natural high polymer cellulose as raw material and series of chemical processing. They are odorless, tasteless and non-toxic white powder, which can be dissolved in cold water to form a transparent viscous solution. Processing thickening, binding, dispersing, emulsifying, film, coating, suspending, absorbing, gelling, surface activity, water maintaining and protective colloid properties
Hydroxypropyl methyl cellulose HPMC is a non-ionic water-soluble cellulose mixed ether. The appearance is white to light yellow powder or granules, tasteless, odorless, non-toxic, it is a chemically stable product, soluble in water, forming a smooth and transparent viscous solution. The production process of HPMC is mainly to form polysaccharide ether products after etherification of cotton fibers. It has no charge itself, does not react with charged ions in cementitious materials, and has stable performance. cheap price. Widely used in dry powder mortar. In mortar, the thickening of the mortar can have a certain wet viscosity, which helps to maintain the amount of free water in the mortar, so that the gel material has more time to hydrate after the mortar is used.
