Diatom mud purchase: what is the function of diatom mud? Use of Diatomite

Core tip: the proven reserves of diatomite in China are 320 million tons, and the high-quality soil is mainly concentrated in Changbai Mountain Area of Jilin Province, accounting for about 2 / 3 of the whole country Most of other deposits are grade 3-4 soil, which can not be directly processed and utilized due to the high content of impurities Many people know that diatomite is the raw material of diatomite, so what are the functions of diatomite? And in what ways? Let's get to know each other! What is the function of diatom mud? The use of diatomite (picture from the network) 1 The function of diatomite 1 Screening This is a kind of surface filtration When the fluid flows through the diatomite, the pores of the diatomite are smaller than the impurities 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 Home of coatings: the proven reserves of diatomite in China are 320 million tons, and the high-quality soil is mainly concentrated in Changbai Mountain Area of Jilin Province, accounting for about 2 / 3 of the whole country Most of other deposits are grade 3-4 soil, which cannot be directly processed and utilized due to the high content of impurities Many people know that diatomite is the raw material of diatomite, so what are the functions of diatomite? And in what ways? Let's get to know each other! What is the function of diatom mud? The use of diatomite (picture from the network) 1 The function of diatomite 1 Screening This is a kind of surface filtration When the fluid flows through diatomite, the pore of diatomite is smaller than the particle size of impurity particles, so the impurity particles cannot pass through and are retained This function is called screening In fact, the surface of filter cake can be regarded as a sieve surface with equivalent average pore diameter When the diameter of solid particles is not less than (or slightly less than) the diameter of diatomite pore, the solid particles will be "screened" from the suspension, playing the role of surface filtration 2 Depth effect depth effect is the retention effect of deep filtration In deep filtration, the separation process only takes place in the "interior" of the medium Some of the relatively small impurity particles passing through the surface of the filter cake are blocked by the zigzag microporous channels inside the diatomite and the smaller pores inside the filter cake Such particles are often smaller than the micropores of the diatomite When the particles hit the wall of the channel, it may be separated from the liquid flow, but whether it can achieve this Point is determined by the balance of inertia force and resistance of particles This interception and screening are similar in nature and belong to mechanical action The ability of filtering solid particles is basically only related to the relative size and shape of solid particles and pores 3 Adsorption adsorption is quite different from the above two filtration mechanisms In fact, this effect can also be regarded as electrokinetic attraction, which mainly depends on the surface properties of solid particles and diatomite itself When the particles with small pores collide on the inner surface of the porous diatomite, they are attracted by the opposite charge The other is that the particles attract each other to form chains and adhere to the diatomite, which are all adsorption 2、 Application of diatomite 1 Diatomite is a high-quality filter aid and adsorbent material, widely used in food, medicine, sewage treatment and other fields, such as beer filtration, plasma filtration, drinking water purification and so on 2, make cosmetics, facial mask and so on Diatomite mask is the use of diatomite adsorption properties, adsorption of impurities in the skin, play the role of deep care and whitening In some countries, people often apply it all over the body to do whole body beauty, which plays a role in skin care 3 Dispose of nuclear waste Of course, diatomite is also used as raw material for decoration wall materials The above content is about the function and application of diatomite, hoping to help you understand diatomite Home of coatings focuses on the news and information of coatings, diatom mud, paint coatings, coating process, fire retardant coatings and coatings, paint coatings, coating process, decoration knowledge and decoration effect map of fire retardant coatings,
