Product Highlights

核心优势

锈转化技术·免喷砂

单宁酸(Tannic Acid)和磷酸(H3PO4)与铁锈(Fe2O3/Fe3O4)发生螯合反应。单宁酸铁呈蓝黑色致密稳定保护膜。磷酸铁呈灰白色钝化层。反应产物均为稳定不可逆的螯合物不再继续锈蚀。免去喷砂工序直接涂刷在带锈钢材表面。

大幅降低维修成本

钢结构维修中喷砂除锈费用占涂装总成本的50-70%。带锈涂装底漆免喷砂节省50%以上的维修成本。特别适合野外/高空/密闭空间等无法进行喷砂作业的钢结构维修场景。

桥梁/储罐/管道维修应用

钢结构桥梁/高架桥的现场维修(无法喷砂)。石化储罐外壁/管道的定期防腐维护。输电铁塔/通信塔的野外高空维修。港口机械/船舶上层建筑的临时防腐。所有已锈蚀但无法喷砂的钢结构表面涂装维修。

Professional coating technology support services

Kexin boasts an experienced coatings R&D and application technology team, providing comprehensive services from substrate analysis, coating selection, and process parameter optimization to on-site application guidance. We work in conjunction with our clients' coating production lines to fine-tune coating application parameters, ensuring optimal coating quality and production efficiency.

Environmentally compliant green manufacturing system

All products are RoHS/REACH certified and meet national environmental standards for VOC content. Water-based and high-solids, low-VOC formulations are continuously iterated to meet increasingly stringent environmental protection requirements. Environmental performance test reports from authoritative third-party testing institutions such as SGS and CTI are provided.

Comprehensive quality control and batch traceability

A comprehensive quality control system is in place from raw material intake to finished product delivery. Each batch of products undergoes rigorous physical and chemical performance testing and coating simulation testing. Batch numbers are fully traceable, allowing for tracking of raw material origins and production process data. Each product comes with a batch test report and product warranty certificate for customer peace of mind.

Construction Guide

施工流程

Surface treatment

Thoroughly clean the substrate to remove oil and rust. Sandblast steel to Sa2.5 grade. Perform surface pretreatment according to product requirements. Ambient temperature 5-40°C, relative humidity...<85%。

Primer/Pretreatment

Select the appropriate primer or pretreatment based on the substrate and product system. Strictly control the film thickness by mixing according to the product ratio. Proceed to the next process after the primer has dried.

Main coating application

Apply the main coating according to the process requirements. Strictly control parameters such as film thickness, temperature, and humidity. Ensure a uniform coating free of sagging and pinholes.

Curing process

Bake or air dry at room temperature according to product requirements. Increase oven temperature gradually and evenly. For room temperature curing, ensure adequate ventilation and humidity.

Inspection and Acceptance

We test all indicators, including film thickness, adhesion, and gloss. Once all indicators pass, we issue a test report and quality assurance certificate, and ship the product in dust-free packaging.
