I. Spray cleaning with cleaning agents to achieve low-foaming or non-foaming methods 1. Add defoamer: more commonly used are
1 silane defoamer, polyether defoamer and low molecular alcohols.
2. Selection of suitable surfactants.
II. Sodium rosinate selection of the following three main methods
1. Commonly used spray low-foaming surfactant compound: polyether, ethylene oxide propylene oxide copolymerization polyoxyethylene ether, soap (such as triethanolamine oleic acid soap).
2. Choose to use the temperature is in the main surfactant cleaning agent near the cloud point: non-ionic surfactant cleaning effect in the cloud point near the best, if the use of the temperature slightly more than the cloud point, you can achieve high efficiency cleaning and low-foaming at the same time. Such as fatty alcohol polyoxyethylene ether surfactants, different carbon chain length and different EO length turbidity point are not the same, so according to the use of temperature to choose the appropriate fatty alcohol polyoxyethylene ether as the main surfactant cleaning agent.
3. Choose professional low-foaming spray surfactant products.
Spray cleaning process: non-foaming surfactants
1、Product properties
Special type of alcohol ether, is a new, low-foaming, efficient, environmentally friendly non-ionic surfactant with 98% biodegradable. It has good compatibility with various surfactants, auxiliaries, additives and solvents, acid resistance, alkali resistance and oxidation resistance.
