Our company has advanced production equipment, such as ICS-6000 dual-system ion chromatograph, gel permeation chromatograph, specific surface area and pore size analyzer, etc. The above equipment can strictly control the content of each component in the product to ensure the quality of the product.

The ICS-6000 dual-system ion chromatograph used by our company can be used for qualitative and quantitative analysis of inorganic ions and organic acids in solutions. The dual-channel design of the chromatograph can achieve dual-purpose use of one machine, and can detect anions and cations at the same time, or two different detection methods. This can double the efficiency, complete multi-index detection with a single injection, and save 50% of time compared to single-channel instruments. And the two channels can be independently controlled according to needs, which is suitable for multi-dimensional analysis of complex samples. Through the precise detection of anions and cations in the material by the dual-system ion chromatograph, the harmful anion residues in the resin curing agent are monitored, the product quality is controlled, and data support is provided for process optimization and environmental compliance.

The gel permeation chromatograph used by our company also plays an important role in the production of casting resins. We use gel permeation chromatograph to determine the molecular weight distribution curve of synthetic resins such as phenolic resin and furan resin to ensure that the molecular weight distribution of each batch of resin meets the technical specifications and production requirements.

The surface area and pore size analyzer plays a role in quality control and R&D guidance in the production of casting materials, and accurately characterizes the surface properties of resins and their carriers. By comparing the pore size changes at different curing stages to judge the degree of reaction, the yield of resin can be predicted.

Through the coordinated application of precision analytical instruments such as surface area and pore size analyzers, gel permeation chromatographs and dual-system ion chromatographs, we have built an intelligent quality assurance system covering the entire process of casting material production. We calibrate instruments daily to ensure that all test data meet certification requirements, and use quantifiable scientific indicators to fulfill the promise of "100% quality" for each batch of products.

Group’s staple product Foundry material instantly break key challenge. The annual output of Furan Resin exceeds 150,000 tons, ranking ahead in the world; Filter products have been recognized as the National Torch Program key high-tech products by the Ministry of Science &Technology, ranking front in Asia for production and sales volume.The National standard systems for certain Foundry materials are based on SQ group standard systems.

With continuous efforts on R&D, SQ obtained hundreds of patents in technology&products. For decades, SQ sets its goal on digital management, invested over billion on imported high-precision analysis and determination-calibration instrument like 3-ICS-6000 Dual-system ion chromatography, 8-Specific surface area&aperture analyzer and Agilent 1260 GPC, etc. Meanwhile, innovation-incentive policies are carried out for senior scientific team from all walks of professional researchers and Top Universities, aiming to combine green&low carbon concept with “one-stop procurement&all-round service” concept. Consequently, SQ keeps provide effective products and considerate service of development-application-process optimization- Eco protection treatment-technical support for customers.
