Use of feed-grade magnesium chloride

Feed-Grade Magnesium Chloride is a highly water-soluble magnesium source feed additive (in compliance with GB 7294-2017). Its core functions are to supplement magnesium for animals, regulate metabolism, and alleviate stress. It is applied in five major scenarios: ruminants, monogastric livestock, aquaculture, pasture/forage magnesium supplementation, and feed industry premixes. I. Ruminants (dairy cattle, beef cattle, sheep, lambs – the core application) Lactating/transition dairy cows (critical demand) Dry period, pre-calving transition, and post-calving lactating cows: rapid magnesium supplementation prevents milk fever (hypocalcemia), hypomagnesemia, and postpartum paralysis; magnesium promotes calcium absorption, stabilizes postpartum metabolism, and increases feed intake and milk yield. Summer heat stress: magnesium balances cellular sodium‑potassium osmotic pressure, alleviates panting, anorexia, and milk drop, and reduces the risk of sudden death. Prevention of grass tetany (hypomagnesemic tetany) in grazing cattle and sheep In spring and summer, fresh grasses are high in potassium and nitrogen but low in magnesium, making animals prone to muscle spasms, collapse, and death. Two application methods: Long‑term addition to mixed concentrates; Dissolve in water and spray onto pasture or add to drinking water – this is the mainstream preventive strategy on farms. Young stock (calves and lambs) Excellent solubility ensures easy absorption by the delicate digestive systems of young animals, supports bone and neurological development, and reduces limb weakness and growth retardation. Can be added to feed or drinking water. Beef cattle and meat sheep finishing Regulates rumen fermentation efficiency, improves protein digestibility, enhances muscle development and meat quality, and reduces stress during transport and regrouping. II. Monogastric livestock (pigs, chickens, ducks, geese, and specialty poultry) Breeding sows and laying hens (reproductive stages) Magnesium participates in reproductive hormone synthesis, reduces soft‑shelled eggs, weak piglets, and stillbirths, and improves fertilization and hatchability; alleviates fatigue stress during peak laying. Poultry and finishing pigs in high‑density production Special use for summer heat prevention, regrouping, and feed‑change stress; prevents feather pecking, leg weakness, and inability to stand; improves bone calcification and reduces culling due to paralysis. Starter feed for piglets and chicks Better water solubility than magnesium oxide ensures rapid absorption in young animals, preventing neurological spasms and growth arrest caused by magnesium deficiency. III. Aquaculture (two major uses: dietary supplementation + water conditioning) Dietary inclusion (specific application of feed‑grade magnesium chloride) Applicable to: Litopenaeus vannamei, mud crabs, Chinese mitten crabs, lobsters, marine fish, and shellfish. During peak molting periods of shrimp and crabs: add 0.3%–0.6% to feed for rapid magnesium supplementation; combined with calcium, it promotes shell hardening, increases molting survival, and reduces soft‑shell, damaged‑shell, and cannibalism.

The Role of Calcium Chloride in Dust Control and How to Use It

The Role of Calcium Chloride in Dust Control and How to Use It In scenarios such as road construction, mining operations, and material stockpiles, large amounts of dust are easily generated. This not only affects operational safety and reduces air visibility but also accelerates equipment wear and causes environmental pollution. Traditional water spraying for dust control offers short moisture retention, requires high-frequency application, and delivers limited effects. In contrast, calcium chloride, with its excellent hygroscopic, water-retaining, and consolidation properties, serves as a highly cost-effective long-acting dust suppression material and is widely used for dust control at various sites. This article briefly introduces its dust suppression principles, core functions, application methods, and safety precautions. I. Core Mechanism of Calcium Chloride in Dust Control Calcium chloride is a highly hygroscopic inorganic salt. Unlike simple wetting with water, it suppresses dust at the source through three physical actions, providing longer-lasting and more stable dust control: Long-acting hygroscopic moisture retention: It has strong deliquescence, actively absorbing moisture from the air to form a moisturizing liquid film on dust and surface layers. Unaffected by high temperatures or dry winds, it completely resolves the issues of rapid drying and recurring dust associated with plain water, significantly extending the dust suppression cycle. Binding and settling of dust: Its aqueous solution penetrates dust gaps and coats ultrafine suspended particles, causing loose dust to agglomerate, grow larger, and settle quickly. This effectively addresses the challenge of controlling fine dust. Surface consolidation for dust prevention: As moisture slowly evaporates, calcium chloride forms a dense crystalline solidified layer on the ground or material surface, binding loose particles and resisting wind erosion and vehicle compaction, thereby eliminating secondary dust lift-off. II. Main Functions of Calcium Chloride in Dust Control Long-lasting dust suppression, cost and efficiency benefits: Plain water spraying typically maintains dust control for only 1–2 hours. A single application of calcium chloride provides long-term dust prevention, greatly reducing spraying frequency and saving labor, equipment, and water costs. It is well-suited for high‑traffic operations such as mine roads and plant areas. Improved environment and enhanced safety: Effectively curbs dust dispersion, increases visibility in work areas, avoids dust‑related safety incidents, and reduces inhalable dust to improve air quality on site, meeting environmental dust control standards. Surface consolidation and extended service life: Reinforces loose particles on gravel roads, temporary construction haul roads, and stockyard surfaces, reduces surface raveling and pothole damage, improves surface evenness and load‑bearing capacity, and prolongs the usable life of temporary sites. Versatility for multiple scenarios, auxiliary flame‑retardant and moisture‑proof benefits: Widely applicable to various dust‑prone sites. For coal and spoil stockpiles, it keeps material surfaces moist, lowers the risk of spontaneous combustion, and provides combined effects of dust prevention, moisture proofing, and auxiliary flame retardation. III. Standard Application Methods for Calcium Chloride Dust Control Calcium chloride dust control is mainly carried out by two methods: solution spraying and granular spreading. Both are simple to operate and highly practical. The specific procedures are as follows: Liquid Solution Spraying Mixing concentration: For ordinary bare soil and plant stockpiles, a 5%–10% aqueous solution is suitable. For severe dust conditions on main mine roads or in windy, open areas, a high‑concentration 30%–35% solution is used. Strictly control the concentration to avoid corrosion to equipment or road surfaces and to prevent failure of dust suppression. Solution preparation: Use industrial‑grade calcium chloride. Add it in batches to clean water, stir thoroughly until completely dissolved, and let it stand to de‑foam before use. Prevent incomplete dissolution due to clumping. Spraying operation: Clear debris from the area and level the surface in advance. Use a water truck or high‑pressure spray equipment to apply the solution evenly, ensuring the area is thoroughly wetted without standing water. After the first application penetrates and dries, a second application may be applied to enhance consolidation.

The necessity of soda ash in photovoltaics

Amid the global wave of green energy transformation, the photovoltaic (PV) industry is thriving as a major force driving China towards its “dual carbon” goals. However, beyond the spotlight on solar cells and modules, there is an unassuming industrial raw material that is often overlooked – heavy soda ash. If quartz sand is the “body” of PV glass, then heavy soda ash is the “lifeblood” that gives it functionality. Indeed, heavy soda ash serves as an indispensable cornerstone for this golden PV industry chain. I. Core Technological Support for the PV Sector PV cells rely on PV glass to achieve photoelectric conversion, and heavy soda ash is an irreplaceable core raw material in PV glass production. In terms of raw material formulation, the combined cost of soda ash and quartz sand accounts for over 70% of PV glass production costs, with soda ash alone representing 40% to 50% of that. Moreover, PV glass differs from ordinary glass – it requires exceptionally high light transmittance to maximize solar energy capture. While low-iron quartz sand is needed, a specific type of soda ash must be used to achieve this critical optical performance. The quality and purity of soda ash directly determine the glass’s light transmittance and, ultimately, the power generation efficiency of the PV module. “Without high-quality heavy soda ash, there is no high-efficiency PV glass.” Thus, heavy soda ash has evolved from a simple industrial raw material into a core technological component of PV manufacturing. II. Structural Rigid Demand Amid Rapid Industry Growth In recent years, China’s PV industry has entered a fast lane of rapid development, driving explosive demand for upstream raw materials. Data show that the share of PV glass in total soda ash demand rose sharply from 8% in 2020 to 21% in 2025, surpassing container glass to become the second-largest downstream application after flat glass. Meanwhile, in 2024, the national output of ultra-clear patterned PV glass reached 28.72 million tonnes, a year-on-year increase of 15.9%. This astonishing capacity expansion translates into a continuous, massive flow of heavy soda ash to production lines, making the absolute consumption of this raw material in the PV sector greater than ever before. The rigid demand for heavy soda ash within the PV industry is becoming increasingly prominent – every link in PV manufacturing relies on a stable supply of this foundational material.
