Embodiment Construction

[0009] The content of the present invention will be described below in conjunction with the accompanying drawings.

[0010] Such as figure 1 Shown: The glass fiber winding method includes the following steps: First, install the glass spindle, the dipping mechanism, the yarn card, the yarn discharge device and the winding tube core in place according to the requirements of the tooling, wherein the running direction of the dipping mechanism is the same as that of the winding tube The axial direction of the mold core is parallel, and the yarn discharge device is set between the dipping mechanism and the winding tube core; then, the glass fiber on the glass spindle passes through the comb installed between the glass spindle and the dipping mechanism, and then passes through the dipping mechanism. Mechanism, and then through the yarn comb installed between the dipping mechanism and the yarn discharge device, it is wound on the winding tube core through the yarn discharge device; th...

Abstract

The invention provides a water-bath degassing method for glass fiber so as to overcome the defect that the electrical performance of the insulated product is reduced as air bubbles and moisture are easily involved in the traditional glass fiber winding method. The main method for solving the problem in the prior art comprises: heating a glue solution in an impregnation mechanism; and sealing the impregnation mechanism at the same time. According to the invention, the viscosity of a resin glue solution is reduced, the impregnation and gas exhaust are facilitated, the vacuum degassing treatment can be performed on the glass fiber at the same time, and the electrical performance of the insulated product is further improved.

Description

technical field [0001] The invention relates to a glass fiber degassing method, in particular to a glass fiber water bath degassing method. Background technique [0002] At present, the glass fiber winding method is to use the unfolded glass fiber to soak the epoxy resin glue, wind it on the winding pipe core, and process it after baking and demoulding. When the epoxy resin glue is prepared, it needs to be stirred several times. Since the epoxy resin glue itself is relatively viscous, a large amount of gas is mixed in during the stirring process, and these gases are not easy to discharge after being mixed with the epoxy resin glue. Moisture and gas have a great influence on the insulation performance of insulation products, which will increase the partial discharge of insulation products and reduce insulation resistance, leaving a great safety hazard for high-voltage electrical appliances. Insulation products involved in gas and moisture will last for a long time The hangin...
