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、天然石膏礦的產地有哪些?

　　I. what is the origin of natural gypsum mine?

　　湖北運城，甘肅景泰，山西臨汾，山東泰安。

　　Yuncheng, Hubei, Jingtai, Gansu, Linfen, Shanxi, Tai'an, Shandong.

　　二、紙面石膏粉在中國市場的原材料是什么?

　　2. What is the raw material of gypsum powder in China market?

　　1、天然石膏、2、脫硫石膏、3、磷石膏。

　　1. Natural gypsum, 2. Desulfurization gypsum, 3. Phosphogypsum.

　　三、天然石膏有什么優點?

　　What are the advantages of natural gypsum?

　　天然石膏粉主要由硫酸鈣形成后煅燒熟石膏(二水硫酸鈣),常數ShengJianCai石膏產品的原材料都是由天然石膏,m *鋼筋高強石膏板可以吸附空氣中的有害物質,無味,并且可以用作醫藥、電磁輻射、甲醛具有較強的吸附能力。

　　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、脫硫石膏粉的形成與組成?

　　IV. formation and composition of desulfurization gypsum powder?

　　脫硫石膏是發電廠燃煤產生的二氧化硫氣體。與碳酸鈣(石灰水)結合后形成固體廢渣(亞硫酸鹽鈣)。然后，亞硫酸鹽鈣經過特殊的工藝(強制氧化)形成石膏(硫酸鈣)，硫酸鈣二水合物通過煅燒形成。現在市場上大部分的原材料是由脫硫石膏石膏板,但有一個關鍵環節在脫硫石膏的形成-強制氧化,鏈接成本非常高,企業為了節省成本,更重要的是不強制氧化這個鏈接,導致流入市場的原材料不是不合格品后強制氧化,所謂的脫硫石膏材料本質上是兩個水亞硫酸鈣。亞硫酸氫鈣是一種不穩定物質。在某些情況下，二氧化硫會被排放出來。二氧化硫會對人體呼吸系統、心血管等功能造成損害。

　　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、磷石膏粉的組成及危害?

　　V. composition and harm of phosphogypsum powder?

　　磷石膏是磷肥和磷酸生產過程中產生的廢棄物。磷石膏中含有氟化物、砷、鎘、鉛、汞等有害重金屬化學物質和放射性元素，對環境造成了數百年的破壞。長期接觸磷石膏會導致骨骼變形和腎臟中毒。對人體的危害是相當嚴重的。六、未來紙面石膏板的原材料選擇?國家現在大力提倡環保，近幾年火電廠將逐步停產，也會導致脫硫石膏的消失，所以石膏板的原料只能選擇天然石膏。七、同樣的天然原料，為什么天然大理石會對人體造成危害?因為天然大理石本身含有一種238U元素，這種元素通過衰變形成放射性元素鐳，再通過衰變形成有毒的氡氣，這種氣體可以附著在人的呼吸系統，導致肺癌。八、既然脫硫石膏、磷石膏對人體有害，國家為什么要允許生產石膏板。目前，電廠和磷肥廠每年產生的廢渣超過2億噸。長期大量的廢渣造成的二期污染十分嚴重，占地面積大。國家為了減少對環境的污染和土地利用,在環境保護和經濟利益,只能鼓勵使用脫硫石膏、磷石膏,但對脫硫石膏和磷石膏過程有嚴格的要求,但是通常無法忍受高環保處理成本,從而導致大量的不合格原材料進入市場。用這些不合格的原材料制作的石膏板對人體危害相當大。這種產品在發達國家是嚴格禁止的。

　　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.
