Coating knowledge: deep disclosure of diatomite mud -- diatomite decolorization

Core tip: diatomite is actually the accumulation of the remains of ancient diatom plants and other single celled organisms Generally, diatomite tends to be white, such as white, gray, gray, etc., because its density is generally only 1.9 to 2.3 per cubic meter, so its internal structure has a large gap, and its porosity is as high as more than 90% when it is dry, so diatomite is particularly easy to grind into powder shape, so the diatomite bought on the market is generally in powder shape Since diatomite is mainly formed by diatoms, it was once or always abundant in Shandong, Jiangxi, Yunnan, Sichuan, etc Shenyang steel structure fireproof coating construction expert punde Building Fire Engineering Co., Ltd Recommended introduction: since its establishment, Shenyang punde Construction Fire Engineering Co., Ltd has cultivated a group of professional construction teams with excellent equipment, rich experience and serious responsibility with advanced and scientific management methods and strict engineering quality assurance and after-sales service system It has undertaken a number of fire system installation projects, which has been praised by customers Every idea and special requirement of you will be fully considered by us and fully realized in the construction technology, which will become the cornerstone of our successful long-term development We are looking forward to your invitation, to provide you with quality services and high-quality technical support! All construction coatings have passed ISO9001 Paint Home News: diatomite is actually the accumulation of the remains of ancient diatoms and other single celled organisms Generally, diatomite tends to be white, such as white, gray, gray, etc., because its density is generally only 1.9 to 2.3 per cubic meter, so its internal structure has a large gap, and its porosity is as high as more than 90% when it is dry, so diatomite is particularly easy to grind into powder shape, so the diatomite bought on the market is generally in powder shape Since diatomite is mainly formed by diatoms, it is mainly found in Shandong, Jiangxi, Yunnan, Sichuan and other places where water was or has been sufficient In addition, with the diversity of processing methods of diatomite, there are many varieties of diatomite products Nowadays, there are mainly three types in the market: montmorillonite, clay and attapulgite Among them, active clay is the most widely used, but if it is used in the processing of edible oil, its requirements will be higher, and its quality is divided into several levels according to different uses In today's international market, the United States is the largest producer of diatomite, with an average annual output of more than 700000 tons, followed by Denmark in Europe, whose products are mainly clay diatomite Although the quantity of diatomite in China is not very small, it is lack of high-quality diatomite Nowadays, the high-quality diatomite is mainly concentrated in the Changbai Mountain generation However, due to the development of market economy and the implementation of relevant policies, the diatomite industry in China is still developing well, which is mainly used for filtering the color of industrial products For the decolorization of diatomite, acid pickling and roasting are generally used now, and in order to further improve the product effect, activated carbon will be added in the current industry to ensure that the colored substances in the solution and other substances that have a negative impact on the product quality are completely absorbed And the ratio of diatomite and activated carbon can refer to 0.2% to 0.3% of the goods And in general, mixing it for 10 to 15 minutes can completely remove the substances that have negative effects on the product Many people will use the simplest resin method when decolorizing the non white diatomite, but in fact, this method is not used, it is easy to have problems, and it can not achieve the expected effect, so it is recommended that you do not be afraid of trouble, or use acid pickling and baking methods, and there are professional equipment in the market, and the price is fair The above is about the decolorization of diatomite I hope it can help you [focus on WeChat official account "paint net"; pay attention to surprises, scan code to see if your husband is selling paint..
