Application

Hongyu calcium products cover a wide range of industrial and fine chemical application scenarios, including construction & metallurgy, agricultural soil improvement, wastewater treatment and flue gas desulfurization, food and feed processing, pulp & papermaking, pharmaceutical excipient production, PVC calcium-zinc stabilizer manufacturing, as well as coatings and nano filler applications.

We supply graded calcium oxide, calcium hydroxide and calcium carbonate (nano-grade included) to address different practical challenges faced by our customers: unstable product purity, insufficient activity, poor pH adjustment effect, high impurity content and inconsistent batch quality.

By matching suitable calcium materials according to each industry’s process requirements, we help clients stabilize production quality, reduce consumption and operating costs, and meet strict industry compliance standards for industrial, food and pharmaceutical grades.

Construction & Metallurgy
news_main_image_weixinjietu_202506171348442377369308916446644
Industry pain points
Low-reactivity quicklime causes incomplete slagging and high lime consumption per ton of steel
Poor mortar water retention leads to cracking and slow construction
High impurities (SiO₂, MgO) cause unstable block strength and batch-to-batch color variation
Suppliers struggle to keep up during peak season — supply interruptions are common
Solution
High-activity calcium oxide from our own Hubei mine, CaO ≥ 90% with consistent particle sizing. Three production lines at 200 t/day ensure continuous supply for oxygen steelmaking, aerated concrete blocks, mortar water-retention and lime-soil road bases — with batch-to-batch consistency you can count on.

Agricultural Soil Amendment
news_main_image_weixinjietu_202506171348442377369308916446644
Industry pain points
Severe soil acidification (pH < 5.5) cuts yield and promotes root disease
Ordinary lime carries heavy metals / impurities that contaminate soil and produce
Insufficient exchangeable calcium causes bitter pit, blossom-end rot and other physiological disorders
Dusty powder spreads unevenly and creates application problems
Solution
Agricultural-grade calcium hydroxide neutralizes acidic soil pH and replenishes exchangeable calcium, with low heavy-metal residue safe for row crops, orchards and greenhouse substrates. Fine, free-flowing powder ensures even broadcast spreading.

Environmental Protection & FGD
news_main_image_weixinjietu_202506171348442377369308916446644
Industry pain points
Acidic wastewater fails discharge limits — compliance fines are a real risk
Low-activity FGD lime means high reagent consumption and operating cost
High insolubles increase sludge volume and downstream disposal cost
Low winter temperatures slow reaction — you need high-activity hydrated lime
Solution
High-activity environmental-grade calcium hydroxide (Ca(OH)₂ ≥ 95%) handles acidic wastewater neutralization, heavy-metal precipitation and wet FGD SO₂ removal in one product. Low insolubles minimize sludge volume, and the particle size is optimized for lime-dosing systems.

Food & Feed Grade
news_main_image_weixinjietu_202506171348442377369308916446644
Industry pain points
Industrial-grade lime exceeds heavy-metal limits (As / Pb / F) and fails BRC / FDA audits
Tofu coagulant produces dark color and low yield
IHigh-ash calcium sources harm animal gut health in feed
Suppliers lack COA, ISO 22000, Halal and other required documentation
Solution
Our 2023 Carlison New Materials plant in Jingshan is dedicated to food- and feed-grade production. Low heavy metals, full COA documentation — suitable for tofu coagulation, bread & cake pH adjustment, cheese processing and feed calcium fortification.
