2.50μm White alumina abrasive:(Does not discolor the surface of ceramic materials and composites).Can not be used for sand blasting in the mouth.
3.SA-85 abrasive :use to remove the glue on the teeth,does not damage tooth enamel,can also use to remove the glue on the restoration and bracket.For bonding metal materials and non-metallic materials prepared.
4.Only provides a medical grade a abrasive,abrasive particles are precisely cut and dried ,uniform size.Low-grade abrasives, due to the presence of oily substances,contaminants or even moisture, can cause equipment to be stuck or intermittently stop sandblasting.
5.Three quarters of volume of abrasive should be installed in the abrasive tank.Abrasive must be clean and dry.
6.Check before use: Gently rotate the abrasive tank. Sand powder should be free to flow. If not free flowing, it indicates that the sand powder is wet and it may stuck the sand blasting gun.
7.The abrasive easily wet, stored in sealed containers.


1.Do not point the nozzle at the face and eyes,wear safety glasses when not using the filter box.
2.Excessive recoil operation will pressurize the abrasive tank causes the abrasive tank to spray or even explode,therefore , the recoil operation should be performed in a safe container.
3.Keep the working tip and target at a distance of 2mm to 10mm,need to use a large suction device operation.
4.Sandblasting should be continuous, repeated sweeping.Not a fast, unstable move.
Touching the etched surface, rough feel is the ideal result. Excessive blasting can damage the surface of the material, especially ceramics.
5.Before processing precious or non-precious alloys and ceramic materials,can experiment on ordinary metals and glass.
6.We recommend that extra grit blasting be operated in the dust box,because the filter box with powder collection system,can absorb excess sand.Abrasive powder floating in the air can cause eye and nose problems,can also damage nearby machines and optical equipment, scratch glasses.
7.Protect the patient's eyes,glass and the nose while operating in the mouth,need to use high-speed suction device. Do not spray the gums.
8.If a rubber dam is not used, the patient should hold his breath while sandblasting.
9.Sandblasting no need to clean.
