黑色石材的研磨翻新
黑色石材的研磨翻新
经常听到客户反映说黑色石材研磨后容易发白,不易出光。那么德国思诺化学就跟大家探讨一下黑色石材如何研磨翻新。黑色石材,庄重大气,端庄肃穆。然而,黑色石材也非常考验设计师的驾驭能力,因为黑色石材并不适合大面积使用。在此先列举常见的黑色石材品种: 黑色花岗石 ①黑金沙;②福鼎黑;③中国黑;④蒙古黑;⑤济南青 黑色大理石 ①黑金花假山制作 不锈钢铸件 铝箔真空袋 七孔梅花管 hdpe硅芯管 液压钢坝 PVC软管 飞行激光打标机 沥青保温泵;②古木纹;③黑白根;④银白龙;⑤黑木纹 石材呈黑色的原因 石材呈黑色,是因含锰和铁元素。黑色石材中的锰和铁元素,主要以“二氧化锰”和“氧化亚铁”形式存在。 1、二氧化锰 化学式为MnO2,黑色无定形粉末,或黑色斜方晶体。难溶于水、弱酸、弱碱、硝酸、冷硫酸,溶于热浓盐酸而产生氯气。 2、氧化亚铁 化学式为FeO,观呈黑色粉末。 黑色石材发白的原因 1、研磨优化不足 黑色石材发白的首要原因,三个字:没磨好。需要指出的是,研磨黑色石材,是禁止跳号的。如果跳号,则会出现“压不住号”的情形,意思是下一级磨片压不住上一级磨片留下的划痕,必然发白。 2、黑色石材遮不住划痕 事实上,无论何种石材上的划痕,都是白色的。大家回想一下,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,无一例外都是白色。这种现象是由光学原理决定的,与材质和颜色无关。 因此,黑色石材遮掩划痕的能力,是最低的。研磨划痕、磨片粗颗粒造成的划痕、鞋底砂砾造成的划痕,这些都易使黑色石材发灰、发白。 3、黑色石材易污染 或许有人认为,黑色石材藏污染能力应该很强吧?这种理解是不对的。黑色属于对比很强的颜色,灰尘、污渍、污染,这些都很容易在黑色石材上显现出来,造成视觉效果发灰、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
