在加工大理石板材的过程中,常遇到板面带有天然裂隙的情况,严重影响荒料的出材率。有些大理石品种锯割成毛板后,数道裂隙贯穿板面,无法进行再加工而报废。采用不饱和聚酯树脂对有裂隙的大理石板进行渗透胶补(以下简称胶补),可取得较理想的效果。上海、北京、丹徒、徐州大理石厂等单位近几年的试用表明:采用胶补工艺比未采用胶补工 In the process of processing marble plates, it is often encountered that the plate surface has natural cracks, which seriously affects the output rate of blocks. After some marble varieties are sawn into wool board, several cracks penetrate the board surface and cannot be reprocessed and scrapped. The use of unsaturated polyester resin to infiltrate the cracked marble plate (hereinafter referred to as glue compensation) can achieve satisfactory results. The trials of Shanghai, Beijing, Dantu, Xuzhou marble factory and other units in recent years showed that: the use of glue repair process is better than the use of plastic repair work.
