          黑色石材的研磨翻新
          經常聽到客戶反映說黑色石材研磨后容易發白,不易出光。那么德國思諾化學就跟大家探討一下黑色石材如何研磨翻新。黑色石材,莊重大氣,端莊肅穆。然而,黑色石材也非??简炘O計師的駕馭能力,因為黑色石材并不適合大面積使用。在此先列舉常見的黑色石材品種: 黑色花崗石 ①黑金沙;②福鼎黑;③中國黑;④蒙古黑;⑤濟南青 黑色大理石 ①黑金花;②古木紋;③黑白根;④銀白龍;⑤黑木紋 石材呈黑色的原因 石材呈黑色,是因含錳和鐵元素。黑色石材中的錳和鐵元素,主要以“二氧化錳”和“氧化亞鐵”形式存在。 1、二氧化錳 化學式為MnO2,黑色無定形粉末,或黑色斜方晶體。難溶于水、弱酸、弱堿、硝酸、冷硫酸,溶于熱濃鹽酸而產生氯氣。 2、氧化亞鐵 化學式為FeO,觀呈黑色粉末。 黑色石材發白的原因 1、研磨優化不足 黑色石材發白的首要原因,三個字:沒磨好。需要指出的是,研磨黑色石材,是禁止跳號的。如果跳號,則會出現“壓不住號”的情形,意思是下一級磨片壓不住上一級磨片留下的劃痕,必然發白。 2、黑色石材遮不住劃痕 事實上,無論何種石材上的劃痕,都是白色的。大家回想一下,日常生活中,小到手機保護膜上的劃痕,大到各種顏色汽車上的劃痕,無一例外都是白色。這種現象是由光學原理決定的,與材質和顏色無關。 因此,黑色石材遮掩劃痕的能力,是最低的。研磨劃痕、磨片粗顆粒造成的劃痕、鞋底砂礫造成的劃痕,這些都易使黑色石材發灰、發白。 3、黑色石材易污染 或許有人認為,黑色石材藏污染能力應該很強吧?這種理解是不對的。黑色屬于對比很強的顏色,灰塵、污漬、污染,這些都很容易在黑色石材上顯現出來,造成視覺效果發灰、發白。 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.
