摘要 |
A filler (1) is envisioned which comprises glass-based granules (2) provided with a sizing composition, in which filler each of the granules (2) consists of a multiplicity of milled glass fragments (3) agglomerated together by the agency of a sizing composition (4) containing especially a compound chosen from esters of alkylsilicic acids, particularly an aminosilane. The process comprises a milling step (6) during which the glassy material is comminuted into fragments by this milling, a metering step (7) during which a mixture including the fragments (3) and the sizing composition (4) is formed and an agglomeration step (8) during which the mixture is dried so as to form granules each including a multiplicity of fragments (3) and dried parts of the sizing composition (4). |
