清理縫隙若縫隙<0.2mm對于縫隙極小的石材拼花，清縫環節，基本上不允許使用機械進行操作。如果采用手提切割機和清縫片等設備，一方面易造成縫隙切割放大;另一方面會產生很高的熱量，導致崩邊等問題，破壞整體裝飾效果。手工清理。選用精工刀片，很薄的那種。有些地方，甚至需要用到更薄的剃須刀片來進行清理。清縫時，速度要慢，避免拼花細節處的破壞。清縫完成后，用大功率的吸塵器，將縫隙處的灰塵吸走。若縫隙>0.2mm拼花面積很(hen)大，縫(feng)(feng)隙(xi)較(jiao)款(kuan)時(shi)，可選用(yong)“手提切(qie)割(ge)機(ji)+0.2mm清(qing)縫(feng)(feng)片”進行清(qing)理。清(qing)縫(feng)(feng)深(shen)度要達到(dao)3mm以上，越(yue)(yue)深(shen)整(zheng)體結構(gou)強(qiang)度越(yue)(yue)高。清(qing)縫(feng)(feng)時(shi)，一(yi)定要保持石材的原(yuan)貌(mao)，不(bu)(bu)要拓寬縫(feng)(feng)隙(xi)。縫(feng)(feng)隙(xi)盡頭處，不(bu)(bu)要切(qie)過了。不(bu)(bu)要切(qie)串縫(feng)(feng)——就是不(bu)(bu)要沿著(zhu)一(yi)條(tiao)縫(feng)(feng)清(qing)理時(shi)，不(bu)(bu)小心(xin)歪出去。
