建筑工程中,大理石、花岗岩等石材作为建筑装饰材料已被广泛运用。但在运输过程或现场施工中,石材容易破损。对于掉棱缺角的石材,我们采用了新的现场修补法,无论是铺贴前修补,还是铺贴后修补,效果都不错,具体做法如下。先清除要修补处的杂屑,使基层洁净、干燥。然后把相同类型石材碎料碾细,掺入适量的环氧树脂粘结剂,充分搅拌后,用灰刀把补料抹到破损处,确保横平竖直。待补料充分凝固后,再用圆面磨光机粘结100、600、800、1000目砂纸,打磨修补部分,基本能使其接近原光洁度。
In the construction project, marble, granite and other stone materials have been widely used as building decoration materials. However, in the process of transportation or on-site construction, the stone is easily damaged. For the stone with missing corners, we have adopted a new on-site patching method. Whether it is patching before or after patching, the results are good. The specific approach is as follows. First remove the debris that needs to be repaired, and clean the base and dry it. Then grind the same type of stone scraps and mix with appropriate amount of epoxy resin binder. After fully mixing, use the gray knife to wipe the feed to the damaged place to ensure horizontal and vertical. After the material is fully solidified, the sanding machine is used to bond 100, 600, 800, and 1000 mesh sandpaper to polish the repaired part, which can basically make it close to the original finish.
