7、塑料工業(yè)：如汽車飾件、儀表板、家電外殼、風(fēng)扇、音箱、燈具總承、鑄件、齒輪、結(jié)構(gòu)件、拉鏈、管材、板材等。3, high hardness, high strength: because of drift beads on silicon aluminum oxide mineral phases (quartz and mullite) formation of hard vitreous, hardness of Morse 6-7, hydrostatic strength up to 70-140 mpa, true density of 2.10 2.20 g/cm3, therefore, drift beads with high strength.General light porous or insulating materials such as boiling rocks, diatomite, perlite, sea pumice, expanded vermiculite is the difference in hardness, strength is poor, with its system of thermal insulation products or light refractory products, intensity difference flaws.The advantages of their shortcomings is drift beads, so drift beads have more competitive advantages, used more widely.
4, excellent electrical insulation, non-conductive: choose after degaussing beads drift beads, is the performance of insulation materials, conductive.Insulation r
