饰面花岗石的评价与研究,进一步明确了饰面石材的装饰性与岩石的矿石物组成有关。在评价花岗石矿床时,应在标准剖面上等间距采取岩矿标本系统鉴定,并按矿物定量法划分石材品种及品级。研究岩体的断裂构造,确定原生节理与石材开采时三向断面的关系,为确定荒料规格、计算成荒率提供理论依据。对石材的研磨加工,建议采用统一的7级系列化磨具,精磨阶段采用微粉研磨,以提高石材的光洁度。制造磨具应选用无机、有机复合型粘结剂。
The evaluation and study of the veneered granite further clarified that the decorative nature of the veneered stone is related to the ore composition of the rock. In the evaluation of granite deposits, should be taken at equal intervals on the standard profile of rock and mineral sample system identification, and by mineral quantitative method for the classification of stone varieties and grade. Studying the fracture structure of the rock mass, determining the relationship between the primary joints and the three-directional section of the stone mining, it provides a theoretical basis for determining the block size and calculating the shortage rate. Stone grinding process, it is recommended that a unified series of 7-series abrasive, fine grinding stage grinding with powder to improve stone finish. Abrasives should be used to create inorganic, organic composite binder.
