The polymer paint coating and sintering device comprises a base, a translation lifting device, a spiral lamp tube, a supporting box and a gas conveying device; the translation lifting device is installed on the base and comprises a guide rod, the guide rod is in sliding connection with a positioning block fixed to the base, and a sliding assembly sliding in the vertical direction is arranged on the guide rod; the spiral lamp tube is detachably connected with the sliding assembly and is connected with a programmable constant-current power supply; the supporting box is fixed on the base through a plurality of supporting rods; and the gas conveying device is fixed to the base through a supporting column and comprises a first gas inlet pipe, a second gas inlet pipe and a gas outlet pipe which are communicated through a three-way conversion structure, and the gas outlet pipe penetrates through the supporting box and extends into the container to be machined. By means of the polymer paint coating and sintering device, the thermal stress of a coating can be effectively reduced, the film forming service life is prolonged, the film forming quality is improved, the integrity of the coating can be guaranteed while the sintering time is shortened, the dewatering effect on the concave bottom surface of the container is improved, the dewatering success rate is increased, and the difficulty of coating the inner wall of the micro container with the macromolecular coating is reduced.

Description

technical field [0001] The invention relates to the technical field of polymer paint coating and sintering, and more particularly relates to a polymer paint coating and sintering device suitable for the inner wall of a micro container. Background technique [0002] The principle of the hydrogen atom frequency standard is to ionize hydrogen atoms into atoms, and focus the high-energy atoms into the storage bubble through state-selective focusing. The storage bubble is placed inside a microwave resonant cavity with a suitable frequency, and the high-energy state atoms interact with the radiation field in the cavity to generate stimulated radiation transitions. The storage bubble needs to be coated with a polymer coating, such as polytetrafluoroethylene, so that the atoms collide with the bubble wall without generating an energy state, and the atoms in the high energy state can have enough time to interact with the radiation field to obtain a very narrow atomic spectrum Line w...

Problems solved by technology

Moreover, if the moisture cannot be completely removed in the step of vacuum dewatering, it is necessary to insulate and degas the inside of the container in the furnace. This process will also cause part of the crystalline coating layer to fall off, affecting the thickness of the coating.

When the container is sintered in the sintering furnace, it faces the problem of uneven temperature: since the temperature sensor is installed on the inner wall of the sintering furnace, there must be a temperature gradient between the center of the sintering furnace and the heating inner wall, and the larger the volume of the sintering furnace, the The temperature gradient is more obvious

Although it has the effect of circulating wind direction compensation, there is a temperature difference from top to bottom at the top, middle and bottom of the container. In addition to bringing thermal stress, the entire coating will flow from top to bottom in a gel state, which may seal the inlet. Gap between air duct and inlet wall

If the gas transmission device has a pressure relief valve, oxygen cannot enter the container, so that the paint stabilizer cannot be fully burned and carbonized, which affects the quality of the crystallized film; if the gas transmission device does not have a pressure relief valve, the interior of the container is gradually pressurized, The paint is sintered in a pressurized environment, so that there is a large stress between the film and the container wall, which affects the life of the film
