Abstract
The invention discloses a self-heating ceramic bushing plate, which is of an integral structure and is composed of a bushing plate body 1, a flange 2, a connecting terminal 3, a connecting terminal 4 and a bottom plate with leaking holes 6, wherein a conducting layer is respectively formed at the outer surfaces of a side face 5 and the external opposite face of the bushing plate by utilization of a high-temperature gas-phase deposition technology; an electrode is further arranged; the conducting layers are used for heating in a low-temperature condition, so that the temperature of the bushing plate for wiredrawing glass fibers is increased; after the temperature of the bushing plate for wiredrawing the glass fibers is increased to a certain extent, the electroconductibility of the ceramic body of the bushing plate for wiredrawing the glass fibers is enhanced, the ceramic body can heat after the ceramic body is electrified, the high temperature is maintained, and the situation that the bushing plate for wiredrawing the glass fibers works persistently and normally is guaranteed; the connecting terminal 3 and the connecting terminal 4 are used for being connected with a heating power supply. According to the self-heating ceramic bushing plate, these ceramic materials are much cheaper than platinum-base alloys, so that large precipitation funds can be saved, fund waste caused by material wastage can be reduced, and meanwhile the manufacture is also convenient.
Description
Technical field
The present invention relates to a kind of bushing plate for glass fiber drawing, especially a kind of spontaneous heating ceramic bushing.
Background technology
Public bushing plate for glass fiber drawing is manufactured by platinum base alloy, platinum and alloy thereof are extremely expensive materials, adopt this material can take a large amount of funds, spillage of material simultaneously is also huge waste, start the sixties at home, once carried out a large amount of " for platinum " research, the most significant achievement is the crucible portion that the other materials of employing cheapness instead of wherein, but bushing part is not also obviously in progress, existing market overwhelming majority bushing plate for glass fiber drawing adopts platinum base alloy manufacture, a large amount of sink moneies and the waste of loss fund can be caused, also can take a large amount of expensive.
Summary of the invention
The object of the invention is to adopt high-purity carborundum material, TiB2 or its synthesize ceramic material substitution platinum and alloy material thereof, make bushing plate for glass fiber drawing, because these stupaliths are all much cheap than platinum base alloy, the fund waste that a large amount of sink money and spillage of material cause can be saved like this, simultaneously also easily manufactured.
Technical scheme of the present invention is achieved in that and adopts high-purity carborundum material, TiB2 or its synthesize ceramic material substitution platinum and alloy material thereof, make bushing plate for glass fiber drawing, adopt high temperature gas phase precipitation technology to produce conductive layer at the outside surface of this material simultaneously, adopt this conductive layer to generate heat like this when low temperature, bushing plate for glass fiber drawing temperature is raised, bushing plate for glass fiber drawing temperature is elevated to a certain degree, bushing plate for glass fiber drawing ceramic body electroconductibility strengthens, self meeting heating power, maintain high temperature, ensure that bushing plate for glass fiber drawing continues normal work.
Accompanying drawing explanation
Accompanying drawing 1 is surface structure schematic diagram of the present invention.
Accompanying drawing 2 is longitudinal profile structural representation of the present invention.
Embodiment
Below in conjunction with accompanying drawing in detail embodiments of the present invention are described in detail:
As accompanying drawing 1, accompanying drawing 2, spontaneous heating ceramic bushing is by bushing body 1, flange 2, splicing ear 3, splicing ear 4, the integrative-structure that base plate 6 with small opening forms, the outer opposite of its side 5 and bushing thereof adopts high temperature gas phase precipitation technology to produce conductive layer at the outside surface of this material, also electrode is set, adopt this conductive layer to generate heat like this when low temperature, bushing plate for glass fiber drawing temperature is raised, bushing plate for glass fiber drawing temperature is elevated to a certain degree, bushing plate for glass fiber drawing ceramic body electroconductibility strengthens, self meeting heating power, maintain high temperature, ensure that bushing plate for glass fiber drawing continues normal work, splicing ear 3, splicing ear 4 are used for connecting heating power supply.
Base plate 6 with small opening has multiple small opening, and glass metal can spill from this some holes.
This ceramic spontaneous heating ceramic bushing by high-purity carborundum material through overcompaction and high temperature sintering manufacture, also can be manufactured by the synthesize ceramic material of TiB2 or its combination formula.
Needs according to bushing size can arrange stiffening web on the base plate 6 of band small opening.
Bushing can arrange screen plate, reduce small opening blocking.
This spontaneous heating ceramic bushing also can make body 4 sides, the band base plate 6 of small opening and splicing ear 3, splicing ear 4 outside make conductivity ceramics, the structure that inner cavity segment adopts non-conductive, wear-resistant ceramic to make.
Because these stupaliths are all much cheap than platinum base alloy, the fund waste that a large amount of sink money and spillage of material cause can be saved like this, simultaneously also easily manufactured.
