The density of building mortar refers to the mass density of a certain proportion of uniformly mixed and stirred cementitious materials, sand and water. As for the component materials of mortar, their respective density is as follows: the apparent density of lime putty (1350kg/m³) > the bulk density of cement (1280kg/m³) > density of water.. read more →

The material composition of ceramic tile adhesive mortar generally includes: ①Cement: inorganic cementing material; ②Redispersible latex powder: enhancing the bonding strength for all substrates (especially non-porous substrates and large-size tiles; or pasted on the smooth surface and unstable substrates), increasing the tensile strength, reducing the elastic modulus, increasing the water retention, improving the workability, and.. read more →

The building gypsum is the main raw material that guarantees the bond strength of adhesive plaster, and should meet the requirements of national standard GB / T 9776-2008.   As for the setting time of building gypsum, the standard requires that the initial setting be greater than 6min and that the final setting be less.. read more →

The cellulose ether can be used as the water-retaining agent. The water retention effects of cellulose ether can prevent the substrate from absorbing moisture too much and too fast, and can prevent the evaporation of water, in order to ensure sufficient water during hydration of cement. Generally speaking, the water-holding capacity of cement slurry will.. read more →

As an additive for cement mortar, the cellulose ether usually has an addition amount not more than 2% of cement mass. For the study on cellulose ether, there has been a long history of research abroad. For example, DOW had successfully developed and marketed as early as 1938. First, the higher viscosity the cellulose ether.. read more →

In the pharmaceutical industry, hydroxy propyl methyl cellulose (HPMC) can act as pharmaceutical excipients. It is widely used in oral drugs such as matrix controlled-release and sustained-release preparations as the release-blocking material to regulate the drug release, or as sustained-release agents, pellets and capsules of coating materials. The most widely used are dimethyl carboxymethyl cellulose.. read more →

In the formulations of building materials, the dosage of cellulose ether is only 0.1% to 1%. But it plays an irreplaceable role. Various applications of cellulose ether in building materials will be introduced as follows. 1. Latex and Latex Building Materials Such cellulose derivatives as MC, CMC, HEC and HPMC can be used in the.. read more →

The water retention property of HPMC is also related to the temperature used, and will decrease with increasing temperature. But in the actual material application, in many circumstances, the dry mortar is often used in construction under the conditions of high temperature (above 40 degrees). In the case of plastering for exterior wall putty under.. read more →

1. CMC and HPMC added to the mortar can play the dual role of water retention and thickening. With the increase of dosage, the layering degree of mortar will decrease. CMC is an ionic cellulose ether, and can react with Ca(OH)2 when added to the mortar. CMC has no obvious improvement in the water retention.. read more →

In the food industry, as a natural food additive, Sodium CarboxyMethyl Cellulose is non-toxic, safe and reliable, with no side effects and excellent performance, and its application is not limited. In food applications, Sodium CarboxyMethyl Cellulose is not only an excellent emulsion stabilizer and thickener, but also has excellent freezing as well as melting stability,.. read more →
