The recommended dosage should be determined based on the bath ratio and degree of soiling; generally, the suggested dosage for soaping is 1~3g\/L (based on working solution). Its strong penetration and emulsifying-dispersing properties can significantly improve color stness and color brightness. Industrial Cleaning and Metalworking: Suitable for degreasing and deoiling of metal parts, heavy oil cleaning of hard surces, with better results when used with ultrasonic or spray cleaning equipment. In the paper industry, it is used for online or off-line washing of paper machine felts, effectively restoring felt air permeability and elasticity, and extending service life. Scenarios with AR-815 Combined Use: If the process requires low-foaming characteristics (e.g., high-pressure spray cleaning), AR-815 can be used; if strong detergency is required (e.g., immersion soaping, heavy oil cleaning), AR-812 is a better choice. The two can be flexibly switched or blended according to actual needs. Notes Recommended storage temperature is 5°C to 40°C, avoid direct sunlight, keep container sealed to prevent moisture absorption and deterioration. Wear chemical safety goggles and protective gloves during operation to avoid long-term repeated contact leading to skin degreasing and dryness. Avoid contact with strong oxidizers to prevent violent reactions. Foam characteristics are moderate; if the application scenario is sensitive to foam, an antifoaming agent can be used or a low-foaming alternative AR-815 can be selected. The above technical parameters are from the measured data of Guoli Chemical's product database. Actual application results may vary slightly due to different working conditions. It is recommended to conduct small-scale tests to confirm the optimal dosage.

Paper Machine Felt Washing: Continuous washing recommended dosage of 0.5-1.5%, intermittent washing can be increased to 2-3%, specific dosage adjusted according to felt contamination level. Precautions It is recommended to wear chemical safety protective gloves and goggles during operation, avoid long-term repeated skin contact to prevent degreasing and drying. Avoid contact with strong oxidizers during use and storage to prevent violent reactions. Recommended storage temperature is 5°C to 40°C, avoid direct sunlight, keep container tightly closed. The product is APEO-free and complies with international environmental regulations, but waste liquid should be properly treated and not discharged directly into natural water bodies.
