Fields of application
- Glass and Ceramics Industry
📌 Glass
Borosilicate glass production: Used in the manufacture of heat-resistant glassware, laboratory vessels (such as beakers), and photovoltaic glass. It lowers the glass melting point while enhancing thermal stability and transparency.
📌 Ceramics
Ceramic glazes: Functioning as fluxing agents and flux components, they enhance glaze lustre and reduce cracking. Commonly employed in tableware ceramics and industrial ceramics (such as insulators). - Chemical raw materials and intermediates
📌 Synthesis of boron compounds
The production of core boron chemical products such as boric acid, boron trioxide, and sodium borohydride, which find extensive application in the pharmaceutical and electronic materials sectors.
📌Detergents and cleaning agents
As an alkaline additive in industrial-grade cleaning agents, it simultaneously emulsifies and disperses oil-based contaminants, making it suitable for cleaning metal surfaces and removing scale from industrial equipment.
📌 Flame-retardant materials
For flame retardant treatment of plastics, rubber and textiles, it forms a heat-insulating layer by releasing boron oxides, thereby inhibiting the spread of combustion. - Metallurgical and Electroplating Industry
📌 Metal refining
As a fluxing agent, it removes impurities (such as oxides and sulphides) from molten metal, thereby enhancing the purity of steel and non-ferrous metals.
📌 Electroplating additives
Improves the adhesion and uniformity of electroplated coatings, commonly employed in zinc and nickel plating processes to enhance the corrosion resistance of the deposit. - Agriculture and other sectors
📌 Agricultural fertiliser
A small amount used as a supplement in boron-deficient soils to promote pollen development and fruit set in plants (strict dosage control is essential to avoid boron toxicity).
📌 Other fields
Used as welding flux, sizing agent in the papermaking industry, and pH adjuster in cosmetics (industrial-grade and food-grade must be strictly distinguished; food-grade applications must comply with national standard GB 1886.214).
Packaging and Logistics
Moisture-proof kraft paper bags: 25kg per bag, with a water-draining plastic liner included Suitable for small-scale trials and laboratory use
Moisture-proof ton bags: 1000kg per bag, with water-draining plastic liner included Suitable for large-scale continuous production
Pallet packaging: 1050kg per pallet
Transportation Notes: Transport in dry, clean covered lorries or vehicles with a canopy. Avoid transporting alongside damp items or coloured raw materials. Protect from rain and moisture.
Storage and Usage Recommendations
Moisture-proof sealing: Prevents caking and maintains product performance.
Store in a cool, well-ventilated area: Avoid high temperatures and direct sunlight to maintain chemical stability.
Store separately: Keep absolutely away from any items that could be mistakenly ingested (foodstuffs, medicines, etc.).
Personal Protection: Storage areas shall be equipped with necessary safety facilities (such as eye wash stations and fire extinguishers). Operators shall wear appropriate protective equipment (such as gloves and respirators), particularly when handling bulk powders, to prevent inhalation of dust and direct skin contact.
