Properties and Application:
1, as a low-foaming detergent or defoamer
L61, L64, F68 for the preparation of low-foaming, high detergency synthetic detergent;
L61 as defoamer in the paper or the fermentation industry;
F68 is used as defoamers in the artificial heart-lung machine blood circulation, preventing air from entering.
2, polyether low toxicity, commonly used pharmaceutical excipients and emulsifiers; are often used in the oral cavity, nasal sprays, eye, ear drops and shampoos.
3, polyether is an effective wetting agent for fabric dyeing, electroplating photographic development and acidic margin, and in sugar use F68, because the water permeability increase for more sugar.
4, polyether is useful antistatic agents, L44 can provide long-lasting synthetic protective effect of static electricity.
5, polyether as a dispersant in emulsion paint. F68 as emulsifier when vinyl acetate emulsion. L62, L64 can be used for pesticide emulsifier, as coolants and lubricants in metal cutting and grinding. As a lubricant during vulcanization.
6, can be used as crude polyether demulsifiers, L64, F68 can effectively prevent the formation of oil pipelines in the hard scale, and for secondary oil recovery.
7, polyether used as paper additives, F68 can effectively improve the quality of coated paper.
8, F38 can be used as emulsifiers, wetting agents, defoamers, demulsifiers, dispersants, antistatic agents, dedusting agents, viscosity modifiers, foam control agent, leveling agent, gelling agent, for the production of agrochemicals, cosmetics, pharmaceuticals; also used for washing metal processing, pulp and paper industry, textile processing (textile, finishing, dyeing, finishing soft), water treatment; also used as a rinse aid.
9, P65 is mainly used in the wool industry, as wool protective agent, was added to the wool carbonization process is about 0.3%, can reduce the damage of wool flakes, reinforcing the single fiber strength of 10%, reduce yarn breakage rate of 10%.
Packaging and Storage: 200Kg iron drum, 50Kg plastic drum. As a general chemical storage and transportation. Store in a dry ventilated place. Shelf life of two years.
