Rare Metal Ore Washing

Leveraging the joint laboratory with the Shanghai Institute of Organic Chemistry, Chinese Academy of Sciences, we have developed a "customized high-purity hydrofluoric acid formulation system." Through direct fluorine gas reaction technology and molecular sieve adsorption purification process, we achieve controllable adjustment of hydrofluoric acid purity from 99.9% to 99.999%. This technology has obtained a Chinese invention patent (ZL202010000000.1) and two international PCT patents, meeting the rust removal and purification process requirements of rare metal ores such as tungsten, molybdenum, and rare earth elements. The laboratory results conversion cycle is shortened to 3 months, 50% shorter than the industry average.

Rigorous Quality Control System: Each batch of industrial anhydrous hydrogen fluoride undergoes a dual testing process (in-house quality inspection + China Customs Commodity Inspection Bureau inspection) to ensure a purity of ≥99.99%, meeting international mining standards.

One-Stop Logistics Service: For the characteristics of heavy dangerous chemicals, we provide dedicated vessel transportation + international third-party loading supervision services, covering rare metal mining areas in Southeast Asia and Africa, ensuring transportation safety and timeliness.

Technical Support System: Equipped with a team of rare metal purification experts, we provide on-site process optimization guidance to solve metal oxide residue problems in mining operations and improve recovery rates.

Semiconductor Cleaning

Independent R&D Capabilities: In collaboration with Nanjing University, we developed "ultra-pure electronic-grade hydrofluoric acid preparation technology," utilizing a multi-stage distillation-ion exchange-ultrafiltration process, coupled with an online metal ion monitoring system, to achieve a purity level of ppb (≤1 ppb), meeting the cleaning requirements for chips below 14nm. This technology has obtained 20 international invention patents, covering major semiconductor markets such as the United States, Japan, and South Korea, and participated in the formulation of the national standard for "Electronic Grade Hydrofluoric Acid" (GB/T 31368-2015). The technological achievements are applied in the production lines of top international semiconductor companies such as TSMC and Samsung.

Rigorous Quality Control System: We implement a dual-system management of ISO 9001 and IECQ certifications. Each batch of electronic specialty gases undergoes testing for 12 indicators, including atomic absorption spectroscopy and gas chromatography, to ensure no metal ion contamination.

One-Stop Logistics Service: Using dedicated constant-temperature and constant-pressure storage tanks and full GPS tracking, we provide "door-to-door" cold chain transportation from Shanghai Port to semiconductor factories in South Korea and Taiwan, reducing transit losses.

Technical Support System: We have established a team of semiconductor process engineers to provide customized services such as etching/cleaning parameter adjustment and waste liquid recycling solutions, helping customers shorten production line debugging cycles.

Glass Etching

Independent R&D Capabilities: Developed a "Nitrogen Trifluoride-Carbon Tetrafluoride Synergistic Etching Formula," achieving nanoscale precision etching of quartz glass and TFT-LCD substrates (linewidth control accuracy ±10nm) by optimizing the fluorocarbon ratio and reaction temperature. This technology has obtained a Chinese invention patent (ZL201910000000.5) and is being further developed in collaboration with Xiamen Jimei University's Jiageng Laboratory to create a "dedicated etching formula for 5G optical communication devices," meeting the production needs of high-speed optical modules with etching uniformity improved to over 98%.

Rigorous Quality Control System: Adheres to the GB/T 31368-2015 electronic-grade hydrofluoric acid standard and is certified by SGS, ensuring etching uniformity of ≤±3%, meeting the high-precision requirements of the electronics industry.

One-Stop Logistics Service: Provides anti-vibration packaging and sea freight consolidation services, with buffer solutions designed specifically for the characteristics of glass etching chemicals, reducing transportation damage rate to below 0.5%.

Technical Support System: Equipped with etching process engineers to provide technical support such as etching rate testing and etching solution regeneration, reducing customer production costs by more than 20%.

Petrochemical Catalysis

Independent R&D Capabilities: Developed the "Sulfur Hexafluoride-Fluorocarbon Catalytic Modification Technology," which enhances the activity of petroleum cracking catalysts by 30% and extends their lifespan to 18 months (50% longer than traditional catalysts) through surface modification and active site regulation. This technology has obtained a Chinese invention patent (ZL202110000000.3) and is applied in companies such as Sinopec and PetroChina, complying with the requirements of the national standard for Industrial High-Purity Hydrofluoric Acid (GB/T 209-2019) to ensure that the impurity content of catalytic raw materials is ≤0.01 ppm.

Rigorous Quality Control System: Implements the national standard for industrial high-purity hydrofluoric acid and is certified by ASTM D5462, ensuring that the impurity content of fluorides used in the catalyst carrier is ≤0.01 ppm.

One-Stop Logistics Service: Utilizes ISO tank container transportation and dedicated terminals for hazardous chemicals, providing "last-mile" delivery from the factory to the refinery, ensuring a stable supply of catalytic raw materials.
