天然石膏粉和化學(xué)石膏粉有什么區(qū)別?濟(jì)南石膏粉廠家對(duì)于您的詳細(xì)介紹,希望能對(duì)您有所幫助。
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、天然石膏礦的產(chǎn)地有哪些?
I. what is the origin of natural gypsum mine?
湖北運(yùn)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(guó)市場(chǎng)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(yōu)點(diǎn)?
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(shù)ShengJianCai石膏產(chǎn)品的原材料都是由天然石膏,m *鋼筋高強(qiáng)石膏板可以吸附空氣中的有害物質(zhì),無(wú)味,并且可以用作醫(yī)藥、電磁輻射、甲醛具有較強(qiáng)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(fā)電廠燃煤產(chǎn)生的二氧化硫氣體。與碳酸鈣(石灰水)結(jié)合后形成固體廢渣(亞硫酸鹽鈣)。然后,亞硫酸鹽鈣經(jīng)過(guò)特殊的工藝(強(qiáng)制氧化)形成石膏(硫酸鈣),硫酸鈣二水合物通過(guò)煅燒形成。現(xiàn)在市場(chǎng)上大部分的原材料是由脫硫石膏石膏板,但有一個(gè)關(guān)鍵環(huán)節(jié)在脫硫石膏的形成-強(qiáng)制氧化,鏈接成本非常高,企業(yè)為了節(jié)省成本,更重要的是不強(qiáng)制氧化這個(gè)鏈接,導(dǎo)致流入市場(chǎng)的原材料不是不合格品后強(qiáng)制氧化,所謂的脫硫石膏材料本質(zhì)上是兩個(gè)水亞硫酸鈣。亞硫酸氫鈣是一種不穩(wěn)定物質(zhì)。在某些情況下,二氧化硫會(huì)被排放出來(lái)。二氧化硫會(huì)對(duì)人體呼吸系統(tǒng)、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(chǎn)過(guò)程中產(chǎn)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(xué)物質(zhì)和放射性元素,對(duì)環(huán)境造成了數(shù)百年的破壞。長(zhǎng)期接觸磷石膏會(huì)導(dǎo)致骨骼變形和腎臟中毒。對(duì)人體的危害是相當(dāng)嚴(yán)重的。六、未來(lái)紙面石膏板的原材料選擇?國(guó)家現(xiàn)在大力提倡環(huán)保,近幾年火電廠將逐步停產(chǎn),也會(huì)導(dǎo)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(huì)對(duì)人體造成危害?因?yàn)樘烊淮罄硎旧砗幸环N238U元素,這種元素通過(guò)衰變形成放射性元素鐳,再通過(guò)衰變形成有毒的氡氣,這種氣體可以附著在人的呼吸系統(tǒng),導(dǎo)致肺癌。八、既然脫硫石膏、磷石膏對(duì)人體有害,國(guó)家為什么要允許生產(chǎn)石膏板。目前,電廠和磷肥廠每年產(chǎn)生的廢渣超過(guò)2億噸。長(zhǎng)期大量的廢渣造成的二期污染十分嚴(yán)重,占地面積大。國(guó)家為了減少對(duì)環(huán)境的污染和土地利用,在環(huán)境保護(hù)和經(jīng)濟(jì)利益,只能鼓勵(lì)使用脫硫石膏、磷石膏,但對(duì)脫硫石膏和磷石膏過(guò)程有嚴(yán)格的要求,但是通常無(wú)法忍受高環(huán)保處理成本,從而導(dǎo)致大量的不合格原材料進(jìn)入市場(chǎng)。用這些不合格的原材料制作的石膏板對(duì)人體危害相當(dāng)大。這種產(chǎn)品在發(fā)達(dá)國(guó)家是嚴(yán)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.
