玄色石材的研磨创新

常常听到客户反应道玄色石材研磨后轻易发白,不容易出光。那么德国思诺化学便跟人人讨论一下玄色石材怎样研磨创新。玄色石材,庄严大气,庄重庄严。但是,玄色石材也异常磨练设计师的驾御才能,由于玄色石材其实不合适大面积运用。正在此先枚举常见的玄色石材种类: 玄色花岗石 ①乌金沙;②福鼎乌;③中国乌;④蒙古乌;⑤济南青 玄色大理石 ①乌金花;②古木纹;③是非根;④雪白龙;⑤黑木纹 石材呈玄色的缘由 石材呈玄色,是果露锰和铁元素。玄色石材中的锰和铁元素,重要以“二氧化锰”和“氧化亚铁”情势存在。 1、二氧化锰 化学式为MnO2,玄色无定形粉末,或玄色斜方晶体。易溶于火、弱酸、弱碱、硝酸、热硫酸,溶于热浓盐酸而发生氯气。 2、氧化亚铁 化学式为FeO,不雅呈玄色粉末。 玄色石材发白的缘由 1、研磨优化缺乏 玄色石材发白的主要缘由,三个字:没磨好。需求指出的是,研磨玄色石材,是制止跳号的。若是跳号,则会泛起“压不住号”的情况,意义是下一级磨片压不住上一级磨片留下的划痕,一定发白。 2、玄色石材遮不住划痕 事实上,不管何种石材上的划痕,都是红色的。人人追念一下,日常生活中,小到手机保护膜上的划痕,大到各种颜色汽车上的划痕,无一例外都是红色。这类征象是由光学道理决意的,取材质和色彩无关。 因而,玄色石材遮盖划痕的才能,是最低的。研磨划痕、磨片粗颗粒形成的划痕、鞋底砂砾形成的划痕,这些都易使玄色石材发灰、发白。 3、玄色石材易净化 大概有人以为,玄色石材藏净化才能应当很强吧?这类明白是纰谬的。玄色属于对照很强的色彩,尘土、污渍、净化,这些皆很容易正在玄色石材上展现出来,形成视觉效果发灰、发白。 Customers are often told that black stones are easy to whiten after grinding and are not easy to light. Then Germany's snow chemistry will discuss with you how to grind and refurbish black stones. Black stone, solemn and solemn, solemn and solemn. However, black stone also tests the ability of the designer to control, because black stone is not suitable for large area use. First enumerates the common black stone stone varieties: black granite, black gold sand; (2) Fuding black; (3) China black; (4) Mongolia black; (5) black and black marble, black and golden flower of Ji'nan; (2) ancient wood grain; (3) black and white root; (4) silver white dragon; black wood grain is black because of manganese and iron. The manganese and iron elements in black stone mainly exist in the form of "manganese dioxide" and "ferrous oxide". 1. The chemical formula of manganese dioxide is MnO2, black amorphous powder or black trapezoid crystal. It is difficult to dissolve in water, weak acid, weak base, nitric acid, cold sulfuric acid, dissolve in hot concentrated hydrochloric acid to produce chlorine gas. 2. The chemical formula of ferrous oxide is FeO, with black powder. The reason for the whitening of black stone is 1. The primary reason for grinding optimization is not white stone. The three word is: no grind. It should be pointed out that grinding black stones is prohibited from jumping. If you jump the number, there will be "no pressure", which means that the next level of grinding can not withstand the scratches left on the first grade abrasive, and it will become white. 2, black stone can not cover the scratches. In fact, no matter what kind of scratches are on the stone, they are all white. Let's recall that in daily life, the scratches on the protective films of mobile phones are large enough to be scratched on all kinds of colors, all of which are white. This phenomenon is determined by optical principle, independent of material and color. Therefore, the ability of black stone to cover scratches is the lowest. Grinding scratches, scratches resulting from coarse grained particles, scratches on sole and gravel, are all likely to make grey stone grey and white. 3, black stone is easy to pollute. Some people think that black stone pollution should be very strong. This kind of understanding is wrong. Black is a relatively strong color, dust, stains, pollution, which are easy to appear on black stone, resulting in visual effects gray and white.yl2819.com国际永利
