Abstract
The invention provides a mixed sand blasting process. According to the sand blasting process, glass sand and garnet sand in a mixing ratio of 4:6 are used, the requirements of the sand blasting process can be satisfied, the cost can be greatly reduced and the sand can be repeatedly used.
Description
Technical field
The present invention relates to a kind of blasting craft of mixing, belong to field of metal surface treatment technology.
Background technology
Tradition stainless steel blasting craft generally only adopts a kind of sand, if adopt glass sand, sandblast rear surface effect is better, but cost is high, and glass sand price is high, and is not durable, and glass sand consumption is large; If adopt red pomegranate sand, sandblast cost is low, and sand cost is low, but sandblast weak effect cannot meet technological requirement.
Summary of the invention
The invention provides a kind of blasting craft of mixing, glass sand and pomegranate sand are mixed, according to certain mixed proportion, overcome above defect, not only make cost, and product quality after sandblast can meet technological requirement.
For solving above technical problem, the invention provides following technical scheme: a kind of blasting craft of mixing, the sand of described blasting craft adopts glass sand and pomegranate sand.
Further, the mixing ratio of described glass sand and pomegranate sand is 4:6.
This mixing blasting craft the present invention relates to, glass sand and pomegranate sand mix use, and mixed proportion is 4:6, greatly reduces cost, and sand is more durable, can be repeatedly used; Through production actual verification, sandblast rear surface quality reaches sandblast quality technological requirement.
Detailed description of the invention
Embodiment 1
For different products, also different to the requirement of blasting craft.For stainless blasting treatment, concrete operation step is as follows.
1, preparation
Select suitable order to count glass sand and red pomegranate sand, the mass mixing ratio that makes the two is 4:6, and sandblast use compressed air must be dried, nothing oil.
2,, before sandblast, employing is covered band, sheet metal, the collar, hardwood plate or rubber etc. protection is covered in non-effective surface.Sand-blasting abrasive must keep cleaning, be dried, and does not allow to use by polluted abrasive materials such as old coating, oxide skin or greases.
3, sandblast
When injection, the angle of nozzle effects on surface should approach 90 °, but slightly smaller, so that abrasive material can just in time not spring back to operator, spray gun is 50～150mm apart from the distance of workpiece.
Sandblast order will cover whole surface for clearance, and nozzle should be with constant speed with rectilinear movement, before rear overlap joint together together and expose clean metal and without variable color patch.
Adjust suitable pressure, if the jet power applying is excessive, injection stream is easy to damage surface of the work.Low pressure produces less injection stream impulsive force, polishes effective; High pressure produces larger injection stream impulsive force, and sandblast efficiency is high, has reduced polishing effect.If compressed air pressure is too high, may disturb mortar flow, working (machining) efficiency reduces on the contrary.Can adjust compressed-air actuated pressure by Manual pressure control valve, should in the time that spray gun is opened, adjust.
Sand-blasting gun translational speed will evenly will not wanted excessive sandblast according to surface of the work corrosion oxide skin removal situation adjustment translational speed at any time and prevented workpiece deformation., particularly thickness of slab≤2mm place has requirement place all to need to be sprayed onto, coverage rate > 99%, workpiece sandblast rear surface roughness is wanted evenly, remove sand grains everywhere, and blow down surface of the work dust with dry compressed air.
4, inspection
Cleannes: in the situation that not amplifying, observe, should be without not allowing residual abrasive material in visible oil, fat, dirt, oxide skin and exogenous impurity and product.
Roughness: adopt roughness sample plate and workpiece to carry out visual comparison, roughness sample plate should check by light-section microscope.
Detailed description of the invention of the present invention does not form the restriction to the application's scope; every within the spirit and principle of the present invention design, any amendment that one of skill in the art can make, be equal to and replace and within improvement etc. all should be included in protection scope of the present invention.
Claims (2)
1. mix a blasting craft, it is characterized in that, the sand of described blasting craft adopts glass sand and pomegranate sand.
2. a kind of blasting craft of mixing according to claim 1, is characterized in that, the mixing ratio of described glass sand and pomegranate sand is 4:6.
