Embodiment Construction

[0040] The application will be described in further detail below in conjunction with the accompanying drawings.

[0041] The embodiment of the present application discloses a method for preparing a tapered mica tube, which specifically includes the following steps:

[0042] Step 1. Preparation of raw materials. Mix mica powder and binder in a certain proportion according to requirements and then stir to obtain raw materials. Organic silica gel adhesive can be used as the binder.

[0043] Step 2. Preliminary shaping. Workers hold pipes to pump raw materials into corresponding preparation molds, and use extrusion equipment to extrude and shape the raw materials in the preparation molds.

[0044] refer to figure 1 and figure 2 , the preparation mold includes a horizontal bottom plate 1, the bottom plate 1 is circular, and the upper surface of the bottom plate 1 is coaxially fixedly connected with a vertical core rod 2. Greater than the cross-sectional area of ​​its upper end,...

Abstract

The invention relates to a preparation method of a conical mica tube, and the preparation method specifically comprises the following steps: raw material preparation: mixing mica powder and a binder, and stirring to prepare a raw material; preliminary shaping is conducted, specifically, the raw materials are fed into a corresponding preparation mold, and extrusion shaping is conducted on the raw materials in the preparation mold through extrusion equipment; and finally forming: sealing the preparation mold, and then heating the preparation mold to a forming temperature so as to cure and form the raw materials. The product is taken out, the preparation mold is taken out and cooled to the room temperature, then the preparation mold is opened, the conical mica tube is taken out and inspected, and the effect that the machining difficulty of the conical mica tube can be reduced is achieved.

Description

technical field [0001] The present application relates to the field of mica tube manufacture, in particular to a preparation method of a tapered mica tube. Background technique [0002] Due to its excellent insulation properties, mica tubes are often used at the electrode output ends of various transmission lines or at line connections for protection. [0003] The existing mica tube is generally manufactured by immersing the mica paper in the corresponding binder, and adding one or more layers of reinforcing material according to the needs, and then winding the tube after the binder dries. Round tubes, and then dry and shape the finished round tubes. [0004] In view of the related technologies mentioned above, the inventor believes that under certain circumstances, such as space constraints or installation requirements, it is necessary to use tapered mica tubes, and the general mica tube forming method needs to wind the processed mica paper into a Conical type, there is a...
