Quality requirements of shot peening glass beads


shot peening glass beads
Peening Glass Bead Features:
    1. both soft and hard - the use of high-quality materials from the production, that is, a certain mechanical strength, sio2 content greater than or equal to 68%, hardness up to 6-7 Mohs, there are enough flexibility, can be used several times, , The spray device the same effect than ordinary glass beads more than 3 times longer life.
    2. uniformity - into a round rate greater than or equal to 80%, uniform particle size, the blasting device after the brightness uniformity throughout the device, not easy to leave a watermark.
    3. can not be replaced - shot glass beads as a grinding material than any other grinding material has the following advantages: In addition to metal grinding materials, than any other media use for a long time, with non-alkaline soda-lime glass material, with Good chemical stability, will not contaminate the processing of metal, can speed up the clean-up, while maintaining the accuracy of the original objects
    4. smooth without impurities - the appearance of spherical particles, no impurities; surface smooth, with good finish, to international and domestic standard level
In this case,
