[Performance and application]
1. As low foaming detergent or defoamer. L61, L64, F68 are used to prepare low foaming and high detergency synthetic detergent; L61 is used as defoaming agent in papermaking or fermentation industry; F68 Used as an antifoaming agent in the blood circulation of artificial heart-lung machines to prevent air ingress.
2. Polyether is very low in toxicity and is often used as a pharmaceutical excipient and emulsifier; in oral cavity, nasal spray, eye, ear drops and shampoo It is often used in the agent.
3, Polyether is an effective wetting agent, can be used in dyeing of fabrics, photographic development and electroplating in acidic baths, using F68 in sugar factories, due to increased water permeability, more Sugar.
4, Polyether is an effective Antistatic agent, L44 can provide long-lasting electrostatic protection for synthetic fibers.
5, Polyether as a dispersant in emulsion coatings. F68 as an emulsifier in vinyl acetate emulsion polymerization. L62, L64 can be used as pesticide emulsifier. It is used as coolant and lubricant in metal cutting and grinding. It is used as lubricant in rubber vulcanization.
6. Polyether can be used as crude oil demulsifier. L64, F68 can effectively prevent hard oil pipeline. scale formation, and recovering. for the secondary oil
7, polyethers As paper additives, F68 can effectively improve the quality of coated paper.
. 8, F38 can be used as emulsifying agents, wetting agents, defoamers, demulsifiers, dispersants, Antistatic agent, dedusting agents, viscosity modifiers, foam control Agents, leveling agents, gelling agents, etc., for the production of agrochemicals, cosmetics, pharmaceuticals; also for metal processing, washing, pulp and paper industry, textile processing (textile, finishing, dyeing, soft finishing), water treatment; Also used as a rinse aid.
9, P65 is mainly used in the wool spinning industry, as a wool protection agent, adding about 0.3% in the wool carbonization process, can reduce the damage of wool scales, enhance the strength of single fiber by 10%, and reduce the yarn breakage rate by 10%.
[Packing, Storage and Transportation]
200kg plastic \ metal pail, 50kg plastic drum.F38, F68 is 20kg white woven bag or 25kg kraft paper bag.
Stored in transport a general chemicals. Stored in a dry, well-ventilated place.
