Vanda Environmental Protection Technology Co., Ltd.'s high-specific surface area calcium hydroxide product
Author:
WD-HAD series high surface area calcium hydroxide is an independently developed product of Shandong Vanda Environmental Protection Technology Co., Ltd., with complete independent intellectual property rights. After more than two years and significant investment in R&D of high surface area calcium hydroxide technology and equipment, high surface area calcium hydroxide products are now in mass production.
Our company's high surface area calcium hydroxide has been used in dry desulfurization applications for extended periods under complex operating conditions in various industries, including coal-fired lime kilns, metallurgical aluminum smelting furnaces, coke ovens, and garbage power generation. Desulfurization efficiency can reach over 97% (experimental report examples: 97.33%~99.7%), and we have signed strategic cooperation projects with multiple companies.
High surface area calcium hydroxide, a strong alkaline inorganic non-metallic powder, has a surface area more than three times that of ordinary calcium hydroxide. It offers unparalleled advantages in gas adsorption, reactivity, fluidity, and reaction speed, thus possessing broad application prospects. In the environmental protection field, it can be used for flue gas desulfurization and wastewater treatment; high surface area calcium hydroxide, as a substitute for baking soda, is currently recognized internationally as an excellent dry desulfurization product. In the construction field, it can be used as an admixture for high-performance concrete and waterproofing materials. In the chemical industry, it can serve as a raw material and additive for fine chemical products. Furthermore, the application value of high surface area calcium hydroxide is also increasingly prominent in the food, pharmaceutical, and new energy sectors.

Efficient Purification, Contributing to Blue Skies: Innovative Application of Wanda Tech's High-Specific-Surface Calcium Hydroxide in Flue Gas Desulfurization
With the continuous tightening of national environmental policies and the advancement of the "Dual Carbon" goals, industrial flue gas treatment, particularly the reduction of sulfur dioxide (SO₂), has become a critical challenge for many energy-intensive industries. Among various desulfurization technologies, dry/semi-dry flue gas desulfurization (FGD) is widely used in sectors like steel, building materials, and waste incineration due to its simple process, no wastewater discharge, and relatively lower investment costs. The quality of calcium hydroxide (Ca(OH)₂), the core reagent in this technology, directly determines the final efficiency of the desulfurization system. Wanda Technology, deeply engaged in the field of environmental protection materials, produces high-specific-surface-area calcium hydroxide through dedicated R&D. This product is becoming a key force in promoting clean flue gas emissions due to its exceptional performance.
