QUALITY SYSTEM AND CERTIFICATES
The titanium dioxide quality system of our factory has passed ISO 9001, ISO 14001, ISO 45001 and SGS.
The factory has realized the whole process of strict control system from raw materials to finished products to ensure zero defects in the production of titanium dioxide: XRF/ICP-MS is used at the raw material end to strictly detect titanium ore (TiO₂≥92%, heavy metals <5ppm); the production process is automatically adjusted by PLC for the hydrolysis temperature (±1℃) and the calcination curve of rotary kiln (±2℃), and the key processes have a CPK of ≥1.33; and the finished products are 100% tested by the HunterLab colorimeter (L*≥96, QUV aging test (ΔE＜1.5) and other 48 tests, and equipped with MES system to realize 72-hour full traceability. HunterLab colorimeter (L*≥96), QUV aging test (ΔE＜1.5) and other 48 tests, and equipped with MES system to realize 72 hours of full traceability, to ensure that the stability of the batch difference <1%.
