The invention can be used for manufacturing various static protection tools, tools and devices and can be used for the static protection treatment to the parts which are required to perform the static protection treatment in all fields.
Description
Technical field
The present invention relates to stupalith and spraying technology, be specially a kind of spraying electrostatic dispersion ceramic and technology of preparing thereof.
Correlation technique
Static is ubiquitous in daily life and production work, as long as have phase mutual friction, contact and separate, just will inevitably produce static and static and discharge.
In the epoch of scientific and technical high speed development, the application of various microelectronics, opto-electronic device is increasingly extensive.Electrostatic discharge (ESD) can change the electrical property of semiconductor element, reduces its performance even damages.Static release can cause the disorder of electronic system, causes plant and instrument fault or malfunctioning.In addition, static discharges and produces static sparking, becomes the potential safety hazard in the inflammable explosive article production, and static electric charge also adsorbs dust, contaminate environment.Static is released in each industrial circle and causes enormous economic loss, and a tree name statistics just reaches hundred billion dollars because of static discharges the financial loss that is caused in the annual in the world only electronic industry.
At present, static hazard has caused people's great attention, and is also more and more higher to the requirement of electrostatic protection.Use and study maximum antistatic materials at present, be in polymkeric substance, to add conducting material such as metal or carbon black to make mostly, can't satisfy intensity and the hardness requirement to manufactured materials such as some frocks, instrument, be difficult to also to solve that these materials self exist easily wears out, wear no resistance, problem such as corrosion-resistant.Electrostatic dispersion ceramic is most advanced, the most safe and reliable at present antistatic material.And the electrostatic dispersion ceramic goods of selling at present, all be in the zirconium white matrix, to add oxide conductor or semi-conductor as the resistance adjustment agent, adopt traditional powder metallurgy process to make, complex process not only, the technical requirements height, the product mechanical and physical performance is relatively poor, the production technology difficulty is higher, cost is higher, causes product price very expensive, and is difficult to make large size or complex-shaped product.
Summary of the invention
The present invention has improved a kind of electrostatic dispersion ceramic and technology of preparing thereof.Because static electric charge accumulation or static discharge all occur in part or body surface, therefore,, just can play safe anti-static effect as long as piece surface has electrostatic dissipative properties.The present invention adopts plasma spraying (or other thermospray) method, electrostatic dissipation ceramic material is sprayed on piece surface, and in the electrostatic dispersion ceramic coating of piece surface formation 0.1～2mm, used electrostatic dispersion ceramic is a zirconium white 10～35%, aluminum oxide 30～85%, titanium oxide 5～35%.
As shown in Figure 1, the present invention adopts plasma spraying method spraying electrostatic dispersion ceramic coating 3 on part base solid 1 surface, can also spray the excessive layer of one or more layers metal between matrix 1 and coating 3, to improve the bonding strength between matrix and the coating.The thickness of electrostatic dispersion ceramic coating 3 is 0.1～2mm, and surface resistivity is 10
5～10
9Ω/
The preparation method of described electrostatic dispersion ceramic coating comprises the steps:
The first step: will spray with zirconium white, aluminum oxide, titanium oxide (or wherein 2 kinds or 3 kinds of mixtures of material) powder by 10～35: 30～85: 5～35 part by weight mix.
Second step: component surface is carried out sandblasting, remove greasy dirt, expose unsalted surface.
The 3rd step: performance (as hardness, thermal expansivity etc.) and service requirements according to the component body material determine whether spraying layer of metal transition layer earlier.
The 4th step: the ceramic powder that mixes is put into the spraying feed appliance, adopt plasma spraying or other heat spraying method that ceramic powder is sprayed on piece surface after the processing as far as possible equably.
The 5th step: according to part precision and service requirements, sprayed surface is processed, used working method is diamond wheel grinding or grinding.
The present invention compares with existing electrostatic dispersion ceramic manufacturing technology, has following advantage and effect:
(1) product electrostatic dissipation (anti-electrostatic) stable performance, long-acting.
(2) production technology and technology are fairly simple, and product percent of pass is high.
(3) can save electrostatic dissipation ceramic material in a large number.
(4) can make the complicated anti-static product of large size or shape more easily.
(5) reduce manufacturing cost.
The present invention guarantees that not only product has good antistatic performance, can also greatly improve the wear resistance of product, erosion resistance, the use properties and the life-span of improving product greatly.The present invention can be used to make various antistatic tools, frock and equipment configuration, and each field requires the anti-electrostatic of anti-electrostatic component to handle.
