Abstract

The invention discloses a microchannel plastic film injection method and a microchannel plastic film injection machine. According to the microchannel plastic film injection method, the pressure difference technology formed by combining high pressure and vacuum is adopted, one end of a microchannel plastic film is arranged in liquid to be injected in a high pressure container, the other end of the microchannel plastic film is arranged in an empty cup of a vacuum container, under the combined pressure difference of the high pressure and the vacuum, and totally-enclosed injection of the microchannel plastic film is achieved. An injection process comprises four main procedures of high pressure end preparation, vacuum end preparation, high pressure injection and vacuum injection. The microchannel plastic film injection machine comprises a rack, a vacuum container cavity, a vacuum container sealing door, a vacuum container sealing piece, a connecting frame, a high pressure container cavity, a high pressure container sealing door and a high pressure container sealing piece. According to the microchannel plastic film injection method and the microchannel plastic film injection machine, the liquid is sealed in the high pressure container and the vacuum container and cannot be volatilized in the atmosphere, therefore, even if toxic and harmful liquid is injected, the pollution to the atmosphere cannot be caused, and environmental friendly injection is achieved.

Description

Technical field

[0001] The invention relates to a microchannel plastic film perfusion method and a microchannel plastic film perfusion machine, belonging to the field of liquid microfilling, in particular to easy liquid perfusion of multiple microchannels. Background technique

[0002] Microchannel plastic film is a new type of plastic film containing parallel hollow microchannels. The diameter of the microchannels is micron (10μm~500μm). For many years, the research group of Professor Xu Zhongbin of Zhejiang University has tracked the cutting-edge technology of international research, and has successfully developed a plastic film product with 19 microchannels within one centimeter width in cooperation with Huatai Plastic Co., Ltd. Microchannel plastic film has many advantages, such as not easy to be bent and closed, small footprint, high pressure bearing capacity, and good heat transfer performance. Therefore, it can be used in anti-counterfeiting packaging, perfume storage, mi...

Embodiment Construction

[0027] The present invention will be further described below in conjunction with the drawings.

[0028] The method of the present invention is a method to realize the fully enclosed perfusion of the microchannel film by using the pressure difference technology formed by the combination of high pressure and vacuum.

[0029] Main process

[0030] (1) Preparation of the high pressure end: Put the liquid storage cup with the liquid to be filled into the cavity of the high pressure container, fix one end of the microchannel plastic film into the liquid cup, close the high pressure container door, and make the microchannel plastic film clamp the door Tighten the hand wheel with the seal to meet the requirements of withstanding high pressure; realize the seal at the high pressure end to prevent the liquid from volatilizing into the atmosphere. For the first infusion, pour the liquid to be infused into the liquid cup after fixing the microchannel plastic film to reduce liquid volatilization...
