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.

The invention discloses a selective vacuum resin hole plugging machine, and relates to a hole plugging machine. The machine comprises a base, supporting stand columns are fixedly connected above the base in a bilateral symmetry mode. The tops of the supporting columns are fixedly connected with melting boxes. A plurality of electric heating tubes are fixedly connected to the side wall of the melting box. A motor is fixedly connected to the top of the melting box, a longitudinal rotating shaft is fixedly connected to the output end of the motor, stirring blades are fixedly connected to the outer side of the longitudinal rotating shaft and located in the melting box, a rotating crushing rod is fixedly connected to the upper portions of the stirring blades, and a plurality of defoaming needles are fixedly connected to the outer side of the rotating crushing rod. The machine is simple in structure, the device is simple in structure and convenient to use, resin stirring and extrusion pump driving are achieved through the single motor in the using process, bubbles in resin are eliminated through the defoaming needle in the using process of the device, the bubble breaking effect is good,and bubble-free selective hole plugging is achieved in cooperation with the camera. In addition, excessive resin can be removed through the device, and the machine is more convenient to use and worthyof popularization.
