Ethylene Glycol Moisture content and color are critical factors in ink productio

In ink formulations, Ethylene Glycol primarily serves as a high-boiling-point solvent. For colored inks—particularly those in lighter shades—solvent color (measured on the Pt-Co scale) is crucial; even slight yellowing can cause color shifts in the final printed product.

HPMC as a Dispersant in Building Finishing

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

Performance Comparison of ATMP and HEDP

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:

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
