Abstract
Spontaneous heating ceramic bushing is by bushing body 1, flange 2, connection terminal 3, connection terminal 4, the integrative-structure of the composition of base plate 6 with small opening, the outer opposite of its side 5 and its bushing produces conductive layer using high temperature gas phase sedimentation in the outer surface of this material, also set up electrode, generated heat using this conductive layer so in low temperature, so that bushing plate for glass fiber drawing temperature is raised, after bushing plate for glass fiber drawing temperature is raised to a certain extent, bushing plate for glass fiber drawing ceramic body electric conductivity strengthens, itself meeting heating power, maintain high temperature, ensure that bushing plate for glass fiber drawing continues normal work；Connection terminal 3, connection terminal 4 are used for connection heating power supply, due to these ceramic materials all it is cheaper than platinum base alloy a lot, can so save fund caused by a large amount of sink moneies and spillage of material and waste, while also easily manufactured.
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, and platinum and its alloy are extremely expensive materials
Material, substantial amounts of fund can be taken using this material, while spillage of material is also huge waste, sixties at home,
A large amount of " for platinum " research was once carried out, most significant achievement is to instead of crucible portion therein using cheap other materials
Divide, but bushing part is not substantially in progress also, and existing market overwhelming majority bushing plate for glass fiber drawing are to use platinum base alloy
Manufacture, can cause substantial amounts of sink money and loss fund to waste, and can also take substantial amounts of expensive.
The content of the invention
The purpose of the present invention be using high-purity carborundum material, titanium diboride or its synthesis ceramic material substitute platinum and its
Alloy material, make bushing plate for glass fiber drawing, due to these ceramic materials all it is cheaper than platinum base alloy a lot, can so save
Fund is wasted caused by saving a large amount of sink moneies and spillage of material, while also easily manufactured.
The technical proposal of the invention is realized in this way：Using high-purity carborundum material, titanium diboride or its synthesis pottery
Ceramic material substitutes platinum and its alloy material, bushing plate for glass fiber drawing is made, while using high temperature gas phase sedimentation at this
The outer surface for planting material produces conductive layer, is generated heat using this conductive layer so in low temperature so that glass fiber wire-drawing leaks
Plate temperature is raised, after bushing plate for glass fiber drawing temperature is raised to a certain extent, bushing plate for glass fiber drawing ceramic body
Electric conductivity strengthens, and itself can heating power, maintenance high temperature, it is ensured that bushing plate for glass fiber drawing continues normal work.
Brief description of the drawings
Accompanying drawing 1 is surface structure schematic diagram of the invention.
Accompanying drawing 2 is longitudinal profile structure schematic of the invention.
Specific embodiment
Embodiments of the present invention are described in detail in detail below in conjunction with the accompanying drawings：
Such as accompanying drawing 1, accompanying drawing 2, spontaneous heating ceramic bushing is by bushing body 1, flange 2, first the 3, second connection of connection terminal
The outer opposite of the integrative-structure of terminal 4, the composition of base plate 6 with small opening, its side 5 and its bushing uses high temperature gas phase sedimentation
Conductive layer is produced in the outer surface of this material, electrode is also set up, is generated heat using this conductive layer so in low temperature so that glass
Glass fiber draw is raised with nozzle plate temperature, after bushing plate for glass fiber drawing temperature is raised to a certain extent, glass fiber wire-drawing
Strengthened with bushing ceramic body electric conductivity, itself can heating power, maintenance high temperature, it is ensured that bushing plate for glass fiber drawing continues just
Often work；First connection terminal 3, the second connection terminal 4 are used for connection heating power supply.
There are multiple small openings on base plate 6 with small opening, glass metal can spill from this some holes.
This ceramic spontaneous heating ceramic bushing can be manufactured by high-purity carborundum material through overcompaction and high temperature sintering, also may be used
Manufactured by the ceramic material that synthesizes of titanium diboride or its combination formula.
Reinforcement can be set on the base plate 6 with small opening the need for foundation bushing size.
Filter can be set on bushing, reduce small opening and block.
This spontaneous heating ceramic bushing may be alternatively configured 4 sides of body, the connection terminal 3 of base plate 6 and first with small opening,
Make conductivity ceramics, the structure that inner cavity segment is made using non-conductive, wear-resistant ceramic in the outside of two connection terminals 4.
Due to these ceramic materials all it is cheaper than platinum base alloy a lot, can so save a large amount of sink moneies and spillage of material
Caused fund is wasted, while also easily manufactured.
