How to strictly control the content of polycyclic aromatic hydrocarbons in color paste?
The raw materials of water-based color paste must undergo safety assessment, which is the key for Shanghai Colorful to strictly control the environmental protection of water-based color paste.
Safety assessment is the first step for Shanghai Caisheng water-based colorants to strictly control harmful substances such as polycyclic aromatic hydrocarbons. In a new formula of environmentally friendly water-based colorants, a safety assessment of each raw material from the chemical structure and synthesis route is required. With rich chemical knowledge and understanding of many chemical synthesis, I consulted many engineers in different chemical fields to ensure that when selecting raw materials, the polycyclic aromatic hydrocarbon limit of the water-based color paste meets safety standards. If Caisheng technicians want to choose a pigment to add to the water-based color paste formula, Caisheng’s safety technical engineers will determine which polycyclic aromatic hydrocarbon structure may cause cleavage based on the chemical structure of the pigment and the synthesis route of the intermediate. Will a catalyst be added, will something be added for other functional improvements? Only when Shanghai Caisheng’s technical engineers complete all evaluations can this pigment be entered into Caisheng’s water-based color paste formula!
Step 2: Comprehensive inspection of raw material storage;
Shanghai Caisheng’s raw material procurement implements strict standards and high requirements;
Step 3: Use safe stainless steel equipment and pipes;
On the Caisheng production line, all equipment and pipe fittings that come into contact with the environmentally friendly water-based color paste use clean stainless steel equipment. Strict control of the production process is an important link to ensure that harmful substances such as polycyclic aromatic hydrocarbons in the water-based color paste enter!
Step 4: Choose safe packaging materials;
Shanghai Caisheng’s water-based color paste packaging barrels are of good quality. The materials of the packaging barrels and the materials of the lining plastic bags have clear internal control quality requirements!
Controlling limited standards such as polycyclic aromatic hydrocarbons in water-based color pastes is an aspect of Shanghai Caisheng’s pursuit of improving product quality!
