  天然石膏粉和化学石膏粉有什么区别?济南石膏粉厂家对于您的详细介绍,希望能对您有所帮助。

  What's the difference between natural gypsum powder and chemical gypsum powder? Jinan gypsum powder manufacturer will give you a detailed introduction, hoping to help you.
  一、天然石膏矿的产地有哪些?
  I. what is the origin of natural gypsum mine?
  湖北运城,甘肃景泰,山西临汾,山东泰安。
  Yuncheng, Hubei, Jingtai, Gansu, Linfen, Shanxi, Tai'an, Shandong.
  二、纸面石膏粉在中国市场的原材料是什么?
  2. What is the raw material of gypsum powder in China market?
  1、天然石膏、2、脱硫石膏、3、磷石膏。
  1. Natural gypsum, 2. Desulfurization gypsum, 3. Phosphogypsum.
  三、天然石膏有什么优点?
  What are the advantages of natural gypsum?
  天然石膏粉主要由硫酸钙形成后煅烧熟石膏(二水硫酸钙),常数ShengJianCai石膏产品的原材料都是由天然石膏,m *钢筋高强石膏板可以吸附空气中的有害物质,无味,并且可以用作医药、电磁辐射、甲醛具有较强的吸附能力。
  Natural gypsum powder is mainly calcined gypsum (calcium sulfate dihydrate) after the formation of calcium sulfate. The raw materials of constant shengjiancai gypsum products are all natural gypsum. M * reinforced high-strength gypsum board can absorb harmful substances in the air, tasteless, and can be used as medicine, electromagnetic radiation, formaldehyde with strong adsorption capacity.

  四、脱硫石膏粉的形成与组成?
  IV. formation and composition of desulfurization gypsum powder?
  脱硫石膏是发电厂燃煤产生的二氧化硫气体。与碳酸钙(石灰水)结合后形成固体废渣(亚硫酸盐钙)。然后,亚硫酸盐钙经过特殊的工艺(强制氧化)形成石膏(硫酸钙),硫酸钙二水合物通过煅烧形成。现在市场上大部分的原材料是由脱硫石膏石膏板,但有一个关键环节在脱硫石膏的形成-强制氧化,链接成本非常高,企业为了节省成本,更重要的是不强制氧化这个链接,导致流入市场的原材料不是不合格品后强制氧化,所谓的脱硫石膏材料本质上是两个水亚硫酸钙。亚硫酸氢钙是一种不稳定物质。在某些情况下,二氧化硫会被排放出来。二氧化硫会对人体呼吸系统、心血管等功能造成损害。
  Desulfurization gypsum is the sulfur dioxide gas produced by coal combustion in power plants. Solid waste residue (calcium sulfite) is formed by combining with calcium carbonate (lime water). Then, calcium sulfite is formed into gypsum (calcium sulfate) by a special process (forced oxidation), and calcium sulfate dihydrate is formed by calcination. At present, most of the raw materials in the market are FGD gypsum board, but there is a key link in the formation of FGD gypsum - forced oxidation. The link cost is very high. In order to save costs, the most important thing for enterprises is not forced oxidation of this link, which leads to that the raw materials entering the market are not forced oxidation after unqualified products. The so-called FGD gypsum material is essentially two water calcium sulfite. Calcium bisulfite is an unstable substance. In some cases, sulfur dioxide will be emitted. Sulfur dioxide will damage the respiratory system, cardiovascular and other functions of human body.
  五、磷石膏粉的组成及危害?
  V. composition and harm of phosphogypsum powder?
  磷石膏是磷肥和磷酸生产过程中产生的废弃物。磷石膏中含有氟化物、砷、镉、铅、汞等有害重金属化学物质和放射性元素,对环境造成了数百年的破坏。长期接触磷石膏会导致骨骼变形和肾脏中毒。对人体的危害是相当严重的。六、未来纸面石膏板的原材料选择?国家现在大力提倡环保,近几年火电厂将逐步停产,也会导致脱硫石膏的消失,所以石膏板的原料只能选择天然石膏。七、同样的天然原料,为什么天然大理石会对人体造成危害?因为天然大理石本身含有一种238U元素,这种元素通过衰变形成放射性元素镭,再通过衰变形成有毒的氡气,这种气体可以附着在人的呼吸系统,导致肺癌。八、既然脱硫石膏、磷石膏对人体有害,国家为什么要允许生产石膏板。目前,电厂和磷肥厂每年产生的废渣超过2亿吨。长期大量的废渣造成的二期污染十分严重,占地面积大。国家为了减少对环境的污染和土地利用,在环境保护和经济利益,只能鼓励使用脱硫石膏、磷石膏,但对脱硫石膏和磷石膏过程有严格的要求,但是通常无法忍受高环保处理成本,从而导致大量的不合格原材料进入市场。用这些不合格的原材料制作的石膏板对人体危害相当大。这种产品在发达国家是严格禁止的。
  Phosphogypsum is the waste produced in the production of phosphate fertilizer and phosphoric acid. Phosphogypsum contains fluoride, arsenic, cadmium, lead, mercury and other harmful heavy metal chemicals and radioactive elements, which have caused hundreds of years of damage to the environment. Long term exposure to phosphogypsum can lead to bone deformation and kidney poisoning. The harm to human body is quite serious. Vi. selection of raw materials for gypsum board in the future? The state now vigorously advocates environmental protection. In recent years, thermal power plants will gradually stop production, which will also lead to the disappearance of FGD gypsum, so the raw materials for gypsum board can only be natural gypsum. 7. Why does natural marble do harm to human body with the same natural raw materials? Because natural marble itself contains 238U element, which forms radioactive element radium through decay, and then forms toxic radon gas through decay. This gas can attach to human respiratory system, leading to lung cancer. 8. Since FGD gypsum and phosphogypsum are harmful to human body, why should the state allow the production of gypsum board. At present, power plants and phosphate fertilizer plants produce more than 200 million tons of waste every year. The second stage pollution caused by a large amount of waste residue for a long time is very serious and covers a large area. In order to reduce environmental pollution and land use, in environmental protection and economic benefits, the state can only encourage the use of FGD gypsum and phosphogypsum, but there are strict requirements for FGD gypsum and phosphogypsum process, but usually can not tolerate high environmental treatment costs, resulting in a large number of unqualified raw materials entering the market. The gypsum board made of these unqualified raw materials does great harm to human body. This product is strictly prohibited in developed countries.
