板岩养护方法技巧:前期预防:石材养护施工前必须进行预防处理,在石材的六面同时涂抹永久性的保护层(该保护层一般都是对石材渗透性较强的材料),堵塞石材表面的微孔。防护后可以令外部污染无法侵入,内部细菌及水份由于与空气隔绝,亦无法产生病变。

中期保护:地面石材的磨损及破损的主要原因是鞋底带进的泥沙所致,所以加设防尘地毯,控制污染来源,将泥沙消除于门外,是保护地面光泽减低维护成本的有效途径。人们平时行走时鞋底的灰尘会带入室内,潮湿天气时灰尘带入量比平时多1215倍,在门口铺设防尘地毯后,人在地毯上行走超过七步,可以去除90%以上的灰尘。不过需要注意的是还必须考虑防尘地毯的基本尺寸,只有足够的行走距离,才可以保证鞋底泥沙去除充分。防尘地毯不可能时刻做清理,还应考虑到防尘地毯吸收污渍的能力,防尘地毯吸污能力一旦饱和,灰尘和泥沙大量析出在地毯表面,后来者有可能会将泥沙带入,雨天加大防尘地毯面积及增加防尘地毯的清理次数。

后期治疗:由于各种特殊环境和条件,在日常生活中除了采用预防及保护措施外,还需对轻微损坏之表面进行治疗。有限公司介绍,以往处理的方式是日常清洗及打蜡抛光。但是打蜡操作工序复杂,费用高,对石材自然光泽影响较大。蜡层易磨损,保养周期短,人工工时耗费大。现在大多采用结晶的方式对石材进行翻新和病变治理后的保护。
