As a key basic chemical raw material in industrial production, persulfates are widely used in many important fields such as pulp bleaching, polymer polymerization, and metal treatment. Their quality, supply stability, and cooperation reliability directly affect the production efficiency and development quality of downstream enterprises, thus becoming core considerations for international customers during procurement. Against this background, the persulfate products of Fujian Zhanhua Chemical (referred to as "China Zhanhua") have stood out in the competition with many global brands. They have not only successfully entered the Brazilian market but also achieved stable selection by Brazilian customers for three consecutive years. This cooperation achievement is not only a proof of Fujian Zhanhua Chemical’s own strength but also reflects the increased recognition of high-quality Chinese chemical brands in the international market, setting an excellent example for Chinese chemical enterprises to expand overseas.
Ⅰ. Full-Process Quality Control, Building a Solid Defense Line for Quality and Safety
The birth of high-quality products is inseparable from strict control over the entire production process. In the raw material procurement link, Zhanhua Chemical has established strict access standards, conducting multi-dimensional evaluation and screening of suppliers to ensure that every batch of raw materials entering the production link meets high-quality requirements, eliminating quality hazards from the source.
During the production and processing process, the company has formulated refined production operation specifications, requiring operators to strictly follow standard procedures. At the same time, it has established a real-time monitoring mechanism to dynamically track and adjust key parameters in the production process, ensuring that the production link is always under control. Before products leave the factory, they must undergo multiple rounds of strict testing, including purity testing, metal impurity screening, active oxygen content determination, and stability testing. The test results must meet both current national standards and the company’s internal quality requirements before entering the market circulation link. This full-process quality control model covering "procurement-production-testing-delivery" has built a solid defense line for the quality and safety of Fujian Zhanhua Chemical’s persulfate products.
Ⅱ. Professional Hardware and Team, Providing Solid Support for Quality Control
Advanced hardware facilities and a professional technical team are important guarantees for Zhanhua to achieve high-quality control. In terms of hardware, the company has automated production lines for persulfates, equipped with industry-leading testing instruments and equipment covering multiple dimensions such as component analysis, purity testing, and stability testing. This ensures the accuracy and reliability of test results, providing a scientific basis for product quality determination.
At the same time, the company has established a professional team for quality testing and technological R&D. Team members have solid professional knowledge and rich industry experience in the chemical field. They can not only skillfully operate various testing equipment but also conduct in-depth analysis of test data, promptly identify potential quality risks in the production process, and propose targeted optimization plans. In addition, the team continuously pays attention to the update and development of industry quality standards, integrates the latest quality control concepts and technologies into the company’s production practice, and continuously improves the level of product quality control, providing solid support for the excellent quality of persulfate products.
Ⅲ. Authoritative Qualification Certifications, Demonstrating Quality Strength and Credibility
Authoritative qualification certifications are important "business cards" for a company’s product quality and a direct reflection of market and customer recognition of the company’s quality. With its pursuit of ultimate product quality, Fujian Zhanhua Chemical has won a number of national and industry-level authoritative qualification certifications, and each certification is a strong proof of its quality strength.
As a national high-tech enterprise and an enterprise with the "Single Champion Product (Sodium Persulfate)" in the manufacturing industry awarded by the Ministry of Industry and Information Technology, Fujian Zhanhua Chemical’s persulfate products have received high recognition at the national level in terms of quality and technology. At the same time, the company has passed the ISO9001 Quality Management System Certification, which indicates that its quality management level meets international standards and can provide customers with continuously stable high-quality products. In addition, the persulfate products produced by the company strictly comply with the GB/T series of national standards—for example, Ammonium Persulfate complies with GB/T26519.3-2021, and Sodium Persulfate complies with GB/T26519.1-2021. The endorsement of these authoritative qualifications and standards not only demonstrates the high-quality credibility of Fujian Zhanhua Chemical’s persulfate products but also gives customers sufficient confidence and guarantee when choosing products.
It is precisely relying on the safety defense line built by full-process quality control, the solid support provided by professional hardware and teams, and the strength and credibility demonstrated by authoritative qualification certifications that "China Zhanhua" persulfates can gain a firm foothold in international competition and win the firm choice of Brazilian customers for three consecutive years. This trust is not only an affirmation of Zhanhua’s quality but also a powerful testimony to high-quality Chinese chemical brands going global—with the reliable support of Fujian Zhanhua Chemical and high-performance persulfate products.
