HPMC, as a dispersant, thickener, and binder in building finishing, is primarily used in the molding of cement mortar and gypsum products. It is used in cement mortar to increase its adhesion, reduce flocculation, improve viscosity and shrinkage, and maintain moisture retention. It reduces moisture loss from concrete surfaces, increases strength, and prevents cracking and weathering caused by wate
China's Sulfuric Acid Price Shake the Global Market
On April 10, 2026, China officially released new regulations, comprehensively restricting the export of ordinary smelting by-product sulfuric acid and industrial sulfuric acid from May 1st. Only high-end electronic-grade high-purity sulfuric acid can be exported in small quantities. Recently, sulfuric acid prices have surged dramatically, exceeding 130%. No one expected that this seemingly ordinar
Differences and Principles of PAC (Polyanionic Cellulose) and CMC (Sodium Carbox
Nearshore, overseas projects, brine wells, deep wells, directional wells → PAC is necessary
Shallow onshore freshwater wells, limited budget → CMC can be used to reduce costs
For low mud viscosity and water loss control → PAC-LV
For increasing viscosity, including sand, while controlling water loss → PAC-HV
ATMP (Aminotrimethylenephosphonic acid) and HEDP (Hydroxyethylidene diphosphonic acid) are both commonly used organophosphonic acid scale inhibitors and corrosion inhibitors, widely applied in water treatment. Each has its own characteristics, and their effectiveness depends primarily on the specific application scenario and requirements. The following is a comparison of their performance:
Which Materials price Are Hit by the Coal Production Shutdown?
Due to the explosion occurred at the Qinyuan Coal Mine in Shanxi Province on May 22, 2026. Local government has ordered a complete shutdown and rectification of 18.7 million tons of coal mine capacity. This event may lead to an upward trend in coal prices.
High-purity sulfamic acid: Why are more and more factories replacing hydrochlori
In industrial cleaning and metal surface treatment, hydrochloric acid and nitric acid have long held a dominant position. They are cheap, react quickly, and have strong descaling capabilities, which sounds ideal. However, equipment supervisors and workshop workers who have actually used them know that the problems these two types of strong acids sometimes bring more than the problems they solve—th
Appearance: Pale yellow to yellow transparent liquid (common effective content ≥40%)
PAPEMP is a high-end phosphonic acid scale inhibitor with scale inhibition capabilities far superior to ATMP and HEDP, especially suitable for harsh water conditions such as high hardness, high alkalinity, high salinity, and high temperature.
Food Industry ：
Acidity Regulator: Neutralizes beverage taste, stabilizes pH, and prevents precipitation.
Preservative: Inhibits microbial growth, extends the shelf life of meat and dairy products.
Quality Stabilizer: Prevents edible oil oxidation, maintains canned food color, and improves cheese texture.
Metal Ion Chelating Agent: Chelates calcium and magnesium ions, optimizing food f
