The powder content is 0.3-0.7% of the total glue, and the liquid content is 1.0-1.2% of the total glue volume. Concrete water-reducing admixture must be added with the mixing water into the mixer and stirred until the specified time. The water-reduci...…
Water Reducing Admixtures are mainly used in areas that experience hot and humid weather for concrete pumping, tremie, and placing. Careful concrete placement becomes required since the "initial" time to set will typically occur 1 hour earlier. It ha...…
The limitations are increased drying shrinkage due to higher water content, cement concrete, and paste-to-aggregate ratio. Higher air contents may be required to provide adequate resistance to freezing, thawing, and salt scaling, and higher air conte...…
As the EO mole numbers increases, so does the hydrophilicity when refined lanolin and ethylene oxide are added. When the EO mole number is increased to 70-75mols, the product becomes more water-soluble. Ethoxylated Lanolin : Ethoxylated Lanolin...…
What's hafnium Diboride Powder? Hafnium diboride can be described as an ultra-high-temperature ceramic that is made of hafnium, boron and other elements. It's an uncommon ceramic that has high heat conductivity and conduction. It is a grey, metallic...…
The gel-pulverizing process on the morphology of the as-synthesized quartz powders. Three hours after the ion exchange process, SiO2 sol was changed into a single lump of gel; when subjected to the gel-pulverizing process, the gel lump was separated ...…
