Application of Hydroxypropyl Methyl Cellulose (HPMC) in Building Materials Hydroxypropyl methylcellulose (HPMC) is made from natural polymer material cellulose. A nonionic cellulose ether produced by a series of chemical processing. And they are an odorless, tasteless, non-toxic white powder. Swell in cold water into a…
The bastic intro of hec and hpmc HEC HEC is made from refined cotton after alkali treatment, in the presence of acetone, using ethylene oxide as ether agent for reaction. The degree of substitution is generally 1.5 ~ 2.0. It has strong hydrophilic and is…
Eighteen questions about mortar technology 1. What materials are used to make building mortar? What is the general use? A: Building mortar is make up of inorganic cementitious materials, fine aggregates and water, sometimes mix with certain admixtures.Construction mortar is often use for masonry (such…
Interpretation of hydroxypropyl methylcellulose HPMC problem 1. Hydroxypropyl methylcellulose HPMC is divided into several types. What is the difference in its use? A: Hydroxypropyl methylcellulose HPMC can be divided into instant-dissolve and hot-dissolve, fast-dissolving products. When it is rapidly disperse in cold water, it disappears…
The difference between concrete and mortar What is concrete? Concrete is a solid material form by cement as cementing material, natural sand and stone as aggregate, mixing with water, casting and solidifying. Concrete aggregate The sand is call fine aggregate, and its particle size is…
Small knowledge of crack-resistant mortar Anti-crack mortar, a mortar make of a polymer emulsion and an admixture, which is make of a crack resistant, cement and sand, which is stir at a certain ratio and which can satisfy a certain deformation and maintain no cracking….
Several problems often encountered in dry-mix mortar in engineering applications Dry-mixed mortar is usually called hydraulic cement mixed mortar. It refers to the physical mixing of aggregates (such as quartz sand). inorganic cementitious materials (such as cement) and additives (such as polymers) which are dried…
Adding directly at the time of production, this method is the simplest and least time-consuming method. The specific steps are: 1. Add a certain amount of boiling water to the stirred vessel with high shear stress (the hydroxyethyl cellulose product is soluble in cold water,…
Simply judge the quality of hydroxypropyl methyl cellulose Hydroxypropyl methyl cellulose has the characteristics of thickening, bonding, dispersing, emulsifying, film forming, suspending, adsorbing, gelling, surface active, retaining moisture and protecting colloids. The scope of application is very wide. 1.Fineness Hydroxypropyl methyl cellulose generally has a…
What is the choice of HPMC viscosity when producing putty powder dry mortar? Methylcellulose MC and hydroxypropylmethylcellulose (HPMC) have stable chemical properties. mildew resistance and water retention, and are not affected by pH changes. The viscosity can be used from 50,000 to 200,000, but in…
