Abstract

The invention discloses a manufacturing method of a three-dimensional spiral glass micro-channel. The manufacturing method comprises the following steps: firstly, manufacturing a millimeter-scale glass capillary tube from a glass raw material; heating glass capillary tube to a sub-melting state and keeping the temperature; fixing one end of the glass capillary tube, stretching the other end of theglass capillary tube in a spiral propelling mode, wherein the stretching track is a spiral line and the stretching direction is tangent to the spiral line, adjusting the stretching speed and the heating temperature according to the stretching process, and in the stretching process, restraining a glass pipeline being refined to guarantee the screw pitch and the diameter of the spiral line. According to the manufacturing method of the three-dimensional spiral glass micro-channel, the glass capillary tube is used as a material, and the three-dimensional spiral glass micro-channel with the diameter of less than 50 microns can be manufactured by adopting a method for restraining spiral stretching in a sub-melting state.

Description

technical field [0001] The invention relates to a method for manufacturing a glass microchannel, in particular to a method for manufacturing a three-dimensional spiral glass microchannel. Background technique [0002] In the field of microchemical and microbiological medical research, microchannels with an inner diameter of less than 50 microns can be used as microreactors and mixers. The types are generally multi-row multi-channel and multi-row single-channel. The inlet and outlet ports are generally used for the rapid mixed reaction of multiple components. The multi-row single channel has two ports, one in and one out. It is generally used for the reaction of two components or the addition of multiple components one by one. Multi-row multi-channel Both single-channel and multi-row single channels can be made by etching, acid etching, hot melting, and bonding, and have high requirements in terms of process complexity, internal channel roughness, pressure resistance and airt...
