Abstract
The invention discloses a graphite paint removing craft on the glass case surface, which is characterized by the following: adopting sandblasting pattern to grind graphite paint layer, driving through compressing air to obtain certain grain size scale sand with certain hardness without impacting the surface of graphite paint, cleaning graphite paint layer.
Description
Affiliated technical field
The present invention relates to a kind of technology of handling the worn-out display tube glass envelope graphite coating abrasive, glass bulb is cleaned out be convenient to reuse.
Background technology
At present, existing equadag coating cleaning technology mainly is to use the glass bulb cullet to carry out autogenous grinding, and water cleans and removes equadag coating then.This kind process water amount is big, and has sewage and produce, and the granularity of glass cullet after autogenous grinding more carefully is unfavorable for reuse, and can cause problems such as cleaning is not thorough.
Summary of the invention
In order to overcome above-mentioned several shortcomings, the present invention adopts blasting craft to clear up the equadag coating of envelope surfaces, can improve residual, the problems such as granularity is meticulous, generation sewage of graphite in the above-mentioned technology.
The technical solution adopted for the present invention to solve the technical problems is: glass bulb is placed in the blasting cabinet, pass through lance ejection to the equadag coating of envelope surfaces through the fine sand that pressure-air blows, sand grains and envelope surfaces collision, because the hardness of sand grains greater than the hardness of equadag coating, therefore can be removed the equadag coating of envelope surfaces.The air velocity that control is sprayed and the particle size range of sand grains make equadag coating peel off fully, and do not want the surface of too much wearing and tearing glass bulb.Can avoid like this washing and problem that autogenous grinding brings.
The invention has the beneficial effects as follows, can thoroughly remove the equadag coating of envelope surfaces fast, and fine sand reuse again, easy to operate simple.
Description of drawings
The present invention is further described below in conjunction with accompanying drawing and example.
Fig. 1 is a structural representation of the present invention.
1. clear glass outer covers, 2. base plates, 3. spray guns, 4. projecting lamps, 5. scavenger fans among the figure, external dust arrester installation 6. connect compressed air 7. air gauges 8. sand hoppers 9. valve 10. rubber gloves 11. gathering holes.
Various piece among Fig. 1 has been formed sand blasting unit, in actual implementation process, at first is to connect compressed air, open exhaust dust arrester installation and projecting lamp, glass bulb to be processed is then put into blasting cabinet by valve (9), and the operative employee stretches into gathering hole (11) with hand, worn rubber gloves (10), pistol (3) carries out blasting treatment to sample surfaces, after sandblast is finished, take out glass bulb, closes compression air, exhaust apparatus and projecting lamp from valve.The frosted that deposits on the periodic cleaning base plate.
Claims (4)
1. technology that is used to clear up the envelope surfaces equadag coating is operated by sandblast and to be finished.It is characterized in that: by the frosted of compressed air-driven, be ejected into the surface of equadag coating, the equadag coating of abrasion envelope surfaces reaches the purpose of cleaning equadag coating, and prevents the wearing and tearing of glass.
2. according to the described technology of claim 1, it is characterized in that: the particle size range of frosted is between 0.125mm～0.42mm, and Mohs' hardness is between 3～6.
3. according to the described technology of claim 1, it is characterized in that: the pressure of compressed air scope is 0.2MPa～0.6MPa.
4. according to the described technology of claim 1, it is characterized in that: the spouting velocity of frosted is at 10～20m/s, nozzle from the required distance of product to be processed at 100mm～300mm.
