Description
Technical field:
The present invention relates to a kind of Zirconium silicate ceramic abrasion blasting bead, a kind of specifically low price, can eliminate internal stress, be used for reinforced metal or plastic workpiece surface-treated Zirconium silicate ceramic abrasion blasting bead.
Background technology:
Metal and plastic workpiece surface-treated method, equipment and technology are well-known, promptly utilize existing sandblast machine to produce high pressure draft and promote blast media, blast media is ejected on various workpiece or the plastic parts, plays effects such as eliminating internal stress, reinforcement and surface attractive in appearance.Be mainly used in following industry and field:
1, metal processing: the cleaning of mould, various metalwork are eliminated the surperficial deburring of internal stress surface Hardening Treatment, various precision casting parts etc.
2, various decoration materials: as the surface treatment of surface treatment, stainless steel and the titanium alloy medicine equipment of watch chain, golf club, phone housing, various door lock surface treatment, stainless steel tableware, the surface treatment of electric appliance casing plastic cement etc.
3, special trade: the elimination internal stress surface strengthening of airplane skin aluminium section bar, aircraft blade, blade of wind-driven generator, automobile holder car engine shell, aluminium alloy wheel hub are handled, the military project firearms eliminate stress surface treatment, space flight equipment workpiece surface intensive treatment etc.
In most of the cases, these equipment and method are not very big according to the different use sandblast diameters of workpiece or material, for example in 0 to 1.18mm scope.
Generally speaking, in order to satisfy the needs of modern industry, eliminate internal stress as surface treatment, these sandblasts must have following character:
---certain mechanical shock intensity (elasticity)
---stronger grindability
---less particle size diameter
---high-density
---high tenacity (unsuitable broken)
---there is not dust during use
---can collect repeated use (reducing cost)
Can find on market that at present limited several elimination internal stress strengthening surface handles maybe the shot-peening that can only handle surface aesthetic:
---the granulated glass sphere sandblast
---the stainless steel sandblast
---the steel wire cut pill sandblast
---the plastic grain sandblast
---the sandblast of corundum matter
---the nut-shell sandblast
Example 1: the granulated glass sphere sandblast is known, adopts natural crystal (quartz sand) to make.At first ore to be pulverized, be processed into powder, according to glass ingredient, make batching then, send into glass melter and melt, form the glass liquid phase, form glass stream then, material stock-traders' know-how per minute cuts into the pearl base 200 times, stirs through ball distributing board, roll into different funnels respectively, fall then by in the identical one-tenth pearl groove that roller constituted of three sense of rotation.The ball base forms smooth complete granulated glass sphere gradually under rotation on the roller and the surface tension effects of himself.
The granulated glass sphere sandblast is cheap because of its raw material, have obvious superiority, manufacture craft simply to be widely used., along with the improvement of people's living condition, but demand to high strength, high specific gravity, high tenacity and snappiness sandblast has appearred also.The proportion of granulated glass sphere sandblast has only 2.49～2.55, SiO
2Content height, poor toughness, broken easily, the user uses can produce very big dust simultaneously, can not satisfy modern environmental requirement.Because of the defective of self light specific gravity, the strength of injection is not enough, so can not satisfy the needs that modern goods is made.
Example 2: stainless steel sandblast and steel wire cut pill sandblast also are known.Its proportion height (7.85), good toughness, ejecting force is big, manufactures simple.It has solved not enough this problem of granulated glass sphere sandblast ejecting force, but because following reason, it still can not solve the practical problems that special cargo is made.
-----proportion is too high
-----anti-poor flexibility
-----generation oxide compound (getting rusty, pollute workpiece)
-----need supporting high-power air compressor machine and sandblast machine (high energy consumption)
It is big to produce noise during-----work
Example 3: the plastic grain sandblast also is novel sandblast, and light specific gravity is simple to operate, and low cost is the substitute of glass sphere sandblast aspect some workpiece, and is helpful to common plasthetics surface treatment.But following deficiency is also arranged, can not satisfy the needs that modern special cargo is made.
-----light specific gravity
-----anti-poor flexibility
-----intensity is low
-----granularity big (few, coverage rate is little) to the workpiece rum point
-----can not collect repeated use
Example 4: the sandblast of walnut particle also is a novel product in recent years, and is cheap.Utilize depleted to eat the walnut shell, the various granularity sandblasts that grinding and processing is sieved.
, good toughness low because of light specific gravity, intensity, self including oily composition, is that other sandblast can't be compared to wooden device surface polishing aspect, and unique effect is arranged.
Example 5: the sandblast of corundum matter also occurs for a long time.Be to adopt Al
2O
3(commercial alumina) melting recrystallization, broken, sieve into various grain size number.Because of it has good neutral proportion (3.6～3.8) and superior hardness (Mohs' hardness 8.3), the multi-angular and special exploitation ability of granularity shape, the derusting of common rough metal processing piece surface, deburring, polishing etc. have been solved.Simultaneously and the sandblast machine compounding practice, to workpiece manually with the sand paper friction less than the place play good effect, improved production efficiency.
But, can not satisfy the needs of some field workpiece because following reason makes it that the limitation of use still be arranged.
---poor toughness
---granularity special (multi-angular)
---exploitation property is strong
---can not collect repeated use (accumulative total use cost height)
Comprehensive above example analyses is not difficult to find out that existing sand-blast material respectively has its advantage and characteristic, also is good blast media.
Example 1: light specific gravity (2.49～2.55) strength high toughness is poor, little, the easy fragmentation of jet velocity strength, use dust very much not compliance with environmental protection requirements, the big labor strength of usage quantity big, can not reclaim repeated use.
But the low surface treatment that is fit to low-grade workpiece of cost.
Example 2:, jet velocity strength better than great (7.8) strength high toughness big, unsuitable broken, easily produce oxide compound (iron rust) pollution workpiece surface.But can reclaim repeated use.
Example 3～4 has same characteristic: proportion is lighter than example 1 glass sphere sandblast (less than 1), anti-poor flexibility, granularity big (few to the workpiece rum point, coverage rate is little), can not reclaims repeated use.
Example 5: proportion (3.85) is between example 1 and example 2.Intensity height, poor toughness, granularity are multi-angular, exploitation property is strong, are the derust ideal materials of polishing of surface, can not reclaim repeated use.
In addition, existing fused ceramic beads and preparation method thereof to be knowing, is that the patent of invention of CN1050589C discloses a kind of fused ceramic beads and uses thereof as the Chinese patent notification number, and disclosed fused ceramic beads contains and covered large-scale ZrO

3Can not be in batching greater than 10%, on the contrary yield rate reduces or even waste product.The present invention considers that from granularity moulding and yield rate sequence number 6 is preferential selections.But protection scope of the present invention is not limited only to above-mentioned prescription.
Compare with the blast media up to now, this Zirconium silicate ceramic abrasion blasting bead has remarkable advantages, and these make Zirconium silicate ceramic abrasion blasting bead of the present invention adorn show in the surperficial application unusual in surface treatment and elimination internal stress, metal-surface strengthening, U.S..
Ball of the present invention is an ordinary method manufacturing.The initial admixtion of being made up of above-mentioned oxide compound or their precursor can melt in electric arc furnace, high frequency furnace or other melting appartus that is fit to.Article one, thin flow of molten materials is divided into little particle by high-pressure blast winding-up, in surface tension, dash forward under freezing air, chilling effect, becomes microballon.Pass through meticulous screening, polishing again.Can make diameter like this is the zirconium silicate abrasion blasting bead of 0～1.18mm.Any method that other sprays molten materials that also available those skilled in the art are familiar with is finished.
Below we adopt several method to test the uniqueness of Zirconium silicate ceramic abrasion blasting bead.
At first select the sandblast machine of same model for use, same air pressure is provided with same jet length, same workpiece, and the sand material that the granularity model is identical, different blast medias deal with various workpieces, seen what variation?
Workpiece is set at ligneous top-grade furniture:
---the nut-shell sandblast is under the effect of high-pressure air power, and orderly forms bump to workpiece, after 10 seconds, checks workpiece surface, and light is arranged, and as smart as a new pin, the sand material can not be used again.
---the plastic grain sandblast is under the effect of high-pressure air power, and orderly forms bump to workpiece, after 10 seconds, checks workpiece surface, does not have light, and all right, the sand material can be used again.
---what the granulated glass sphere sandblast was orderly clashes into workpiece, after 10 seconds, checks workpiece surface, rough pit occurred.The sand material can be used again.
---stainless steel and steel wire cut pill sandblast are clashed into workpiece, after 10 seconds, check workpiece surface, very dark wounding occur, and a small amount of sand material has entered in the workpiece timber.The sand material can be used again.
---Zirconium silicate ceramic abrasion blasting clashes into workpiece, after 10 seconds, checks workpiece surface, slightly dark rough pit occurs, and the sand material can be used again.
Workpiece is set at the apparatus of stainless steel or titanium alloy material:
---nut-shell sandblast and plastic grain sandblast are adopted and are used the same method to its bump, after 10 seconds, check workpiece surface, and almost without any variation, the sand material all is out of shape.
---the granulated glass sphere sandblast is clashed into workpiece, checks workpiece surface after 10 seconds, little inferior optical phenomenon occurs, carries a thread of light secretly.65% fragmentation of sand material can not re-use.
---stainless steel or steel wire cut pill sandblast are clashed into workpiece, check workpiece surface after 10 seconds, occur recessed
The pit of protruding injustice does not have light and inferior light, and the sand material can use.
---the sandblast of corundum matter is clashed into workpiece, checks workpiece surface after 10 seconds, does not have inferior light and light, and integral grinding removes one deck.The sand material pollutes can not reclaim use.
---Zirconium silicate ceramic abrasion blasting bead clashes into workpiece, checks workpiece surface after 10 seconds, complete inferior light, very smooth, and effect is very obvious.The sand material does not have fragmentation to re-use.
By the surface treatment of two kinds of unlike material workpiece, that can see goes out the special efficacy of different blast medias to different workpieces.From kinetics, the same impellent promotes the object that particle diameter is the same, proportion is different, can produce different speed and impact force.
Because solid sand material surface shape is different, under the effect of impellent, the friction with air dielectric in the injection also is different.
Nut-shell sandblast---irregular rhombus
Corundum matter sandblast---irregular many prismatics
Stainless steel casting sandblast---regular first pearl
Steel wire cut pill sandblast---rule section shape
Granulated glass sphere sandblast---regular first pearl
Zirconium silicate abrasion blasting bead---regular first pearl.
Adopt common family expenses antitheft door before spraying paint, to carry out the surface processing of derusting:
---nut-shell sandblast and the sandblast of plastic cement particle are carried out kind surface treatment in 10 seconds to it, are substantially not act on.
---the granulated glass sphere sandblast is handled the bump that workpiece carried out for 10 seconds, and workpiece metal oxide compound (iron rust) removes 60%, sand material fragmentation 50%, and waste is serious.
---stainless steel and steel wire cut pill are handled the bump that workpiece carried out for 10 seconds, and the workpiece metal oxide compound removes 90%, and rugged pit appears in the surface, shows as not too suitable.
---the sandblast of corundum matter is handled the bump that workpiece carries out 10 seconds kinds, and the workpiece metal oxide compound removes 100%, surface-brightening, and because of it has unique exploitation, effect is very obvious.
---Zirconium silicate ceramic abrasion blasting bead is handled the bump that workpiece carries out 10 seconds kinds, and the workpiece metal oxide compound removes 75%, and is undesirable.
Elevator inner decoration material stainless steel materials carries out striped or inferior optical processing (sheet metal thickness is set at 0.75mm):
---known nut-shell sandblast and plastic grain sandblast do not have effect substantially, can get rid of.
---the sandblast of corundum matter is handled the bump that workpiece carries out 10 seconds kinds, striped occurs but does not have inferior light.
---the stainless steel sandblast is handled the bump that workpiece carries out 10 seconds kinds, striped and inferior light do not occur, surface irregularity,
---the granulated glass sphere sandblast is handled the bump that workpiece carries out 10 seconds kinds, and striped occurs, and inferior light is arranged but with being cut.(because of the abrasion blasting bead fragmentation)
---Zirconium silicate ceramic abrasion blasting is handled the bump that workpiece carried out for 10 seconds, clear-cut texture, and very beautiful inferior light occurs.(not having broken abrasion blasting bead)
By contrast as can be seen, the existence of various blast medias all has its reasonableness, and suitable sandblast deals with suitable workpiece, and the ideal effect is just arranged.Zirconium silicate ceramic abrasion blasting bead of the present invention has demonstrated the singularity that it is handled some field workpiece.
