On section, the appropriate bound blind area for filling up glass sand and shot iron sand percussion intensity of energy；（2）The light weight of ceramic sand but
Hardness is high, is very suitable for the abrasive blastings such as titanium alloy, aluminium alloy, high temperature alloy and strengthens and be molded（3）Environmental protection, to processing part without
Iron pollution, generates that dust is few, working environment more cleans, no silicosis hidden danger, harmless；（4）Ceramic sand was recycling
Indeformable in journey, abrasion are low, when can guarantee batch production, the consistency of surface sand-blasting effect；（5）Ceramic sand sphericity is high, table
Face is smooth, relatively low to equipment loss；（6）Ceramic sand possesses more extensive particle size range, disclosure satisfy that more application demands, such as
For in military domain（The hot investment castings such as aircraft turbine blades, axis parts, ordnance, the surface of various gear of the spring hydraulic parts are strong
Change is handled, and eliminates internal stress）And civil field（It is stainless steel tableware, for kitchen use for titanium alloy and stainless steel workpiece and product
The tool cleaning of the various metal products such as tool, textile machinery component, impact forging pressure grinding tool, machine pressure grinding tool, medical instrument, surface essence
Whole and surface preparation, descale, derust, deburring, reinforcing, polishing treatment）.Concrete application type is divided into digital class：Electricity
The metals such as brain, mobile phone, camera, tablet, plastic outer and built-in part, surface finishing processing；It is mechanical：Mechanical appearance entirety sandblasting
Polishing, finish, reducing metal true qualities promote visual effect and texture；Hardware class：Metal parts polish, deburring, deoxidation
Skin derusts, degreases, spraying pre-treatment；It is pipeline-like：The metallic conduits such as copper pipe, steel pipe, inside and outside wall cleaning polishing；Mold class：Glass
The derusting of the mold cleanings such as glass bottle, tire, dirt and impurity cleaning.
Although in addition, ceramic sand has a wide range of applications in terms of surface treatment, its defect also can not be ignored：Such as（1）
The Vickers hardness of conventional ceramic sand is ≈ 700HV, and hardness is larger, its toughness is made to become obvious defect, the work of blasting treatment
Part effect is still to be improved；（2）For the HLD-B20 ceramic sands that grain size is larger, cost is higher, when ceramic sand is through excessive
Occur to be crushed after secondary recycling, use can not be recycled, i.e., service life is to be improved；（3）For HLD-B20 ceramic sands, grain
Diameter is larger, is much unable to reach roughness after the processing of the ceramic sands such as HLD-B120, HLD-B150, HLD-B205.
