Preparation method and use method of propofol phosphate gas defoamer

Abstract

The invention belongs to the technical field of textile auxiliaries and discloses a propofol phosphate gas defoamer. The propofol phosphate gas defoamer is prepared from the following components in parts by weight: 0.1 to 0.8 part of propofol phosphate, 0.5 to 1.7 parts of ipratropium bromide, 100 to 150 parts of nitrogen, 15 to 20 parts of helium, 1 to 4 parts of oxygen, 0.1 to 1.5 parts of carbonic oxide, 12 to 14 parts of argon and 10 to 15 parts of ethanol. The preparation method of the propofol phosphate gas defoamer comprises the following steps: dissolving propofol phosphate into an ethanol solution, heating and stirring at the temperature of 30 to 40 DEG, collecting evaporation gas and mixing the evaporation gas with nitrogen; then mixing the mixed gas with isopropyl ammonium bromide aerosol, subsequently carrying out ultraviolet irradiation treatment for 1 to 2 hours, and mixing a treated mixture with other gases, thus obtaining a finished product. The gas defoamer is introduced into the bottom of a working bath for use, wherein the use amount of working solution per liter is 1 to 2L per minute; by means of adding gas, the dispersion uniformity of the working bath is improved; at the same time, a good foam eliminating and inhibiting effect is achieved; the propofol phosphate gas defoamer can be recycled and is high in economic benefit.

Description

[0001] Technical field: [0002] The invention belongs to the technical field of application of textile auxiliaries, in particular to a propofol phosphate gas defoamer. [0003] Background technique: [0004] A large amount of surfactants are used in the dyeing and finishing process of textiles, so it is inevitable to generate air bubbles in the working bath, but the air bubbles will not only cause inaccurate work and measurement, but also make the dyeing and finishing process uneven, and more importantly, foam Overflow will cause the loss of working fluid and pollute the production environment. In serious cases, it will affect the cloud of high-temperature spray dyeing agent and overflow dyeing machine, resulting in abnormal work. [0005] Mineral oils, amides, lower alcohols, fatty acids and fatty acid esters, phosphoric acid esters and other organic defoamers have been researched and applied earlier, and belong to the first generation of defoamers, which have the advantages ...

Problems solved by technology

Sometimes it can be reused according to its inverse solubility, but there are few types of such defoamers at present, and they are still in the research and development stage, and the production cost is high

[0009] Polyethylene is used as a softener in the field of textile auxiliaries. The low-molecular-weight oxidized polyethylene is stirred in a potassium hydroxide medium and an emulsifier to make it stable overnight. When an anionic emulsifier is used, the obtained overnight smoothness Good resistance to heat but poor heat resistance. When using cationic emulsifier, the overnight stability is not high. When using non-ionic emulsifier, although the emulsification process is difficult, the obtained emulsion has good stability and low yellowing when heated.

[0010] The defoamer is generally in the form of solid or liquid, which is difficult to recycle after adding, which will cause a burden to the environment. During the dyeing and finishing process, the fabric needs to be treated by padding and so on. Through ventilation, the dispersion uniformity of the mixed working liquid can be improved. , to speed up the reaction, but due to the presence of surfactants, the aeration operation is prone to generate bubbles
