1、干磨清理:
用150目磨片干磨一次,去除石材表面的老化层、氧化层,打开石材毛孔,确保后期石材保护剂的有效渗透;
2、涂刷防护:
涂刷复合纳米硅氧烷保护剂。在石材研磨过程中,无需担心水进入石材,导致石材病变。进入的水会自行挥发和干燥。这是人造石的特点。操作时,注意保持石材清洁干燥,将防护剂倒入干净干燥的水桶中,用水涂湿,确保均匀充足。一般情况下,保护剂可在石材表面停留20至30分钟,视为足够;涂抹防护剂后,在室温下保持健康48小时,每降温10度,保持健康的时间延长2-4倍;另外,注意沿缝涂刷氟化物防护剂,防止后期渗胶;
3、开缝补胶:
陈牛人造无机石不易开缝,如有开缝,待石材保护剂表面干燥后,可用无尘开缝机开缝,补云石胶;
4、石材研磨:
保护剂养生时间结束后,用150目带水磨平石材;
5、石材酸洗:
研磨150目后,确保石材表面清洁干燥,酸洗。
操作如下:
使用花岗岩清洁剂+花岗岩水斑净+将水按1:1:1的比例混合,然后用地刷或手刷酸洗2-3次(酸洗至孔洞清洗干净),每次两次半,每次清洗等待40分钟,然后用吸水机吸出药液。注:这一步一定不能水洗,否则不能补胶;
6、修补孔洞:
如果不考虑损坏,一般不需要修复孔。如有必要,根据甲方的要求,选择相应的大理石胶或晨牛,提供特殊的原材料进行修复,以确保孔的空气排出。胶干后,再用150目研磨,直至石材表面光滑;
7、逐级研磨:
150目研磨结束后,逐级研磨至3000目;
8、涂刷防护:
选择防水或防油的油性防护剂。要求与干磨石后涂防护剂一样,必须遵循清洁、干燥、充分、均匀、等级、健康的原则,健康时间为防护剂干燥后施工;
9、循章抛光:
可选用大理石抛光剂进行抛光。
Gray terrazzo is a classic terrazzo - the background color is gray, with black, white and various gray gravel textures on it
Shop prefabricated inorganic terrazzo to brighten your eyes when you enter the door; Cleanliness is the first impression, and comfort is a long-term experience; Do not publicize, do not dominate, quietly create a sense of comfort, there is no sense of existence, but there is an indelible concrete existence.
The surface hardness reaches grade 5-7, which is close to the surface of high hardness granite and has better wear resistance. Anti slip and wear-resistant. Because it is ground with crushed stone cement, it has good anti-skid, wear resistance and bearing capacity.
