Classification of diatom mud: diatom

Core tip: we all know that diatom mud contains diatomite, so do you know what diatom is? Diatom is a kind of single celled algae with pigment body, which is often connected into a variety of groups by several or many cell individuals It belongs to the producer in the food chain, and is mainly characterized by the cell wall covered with siliceous substance (mainly silica) outside the diatom cell Fossil remains show that diatom originated in the early Jurassic at the latest Diatoms (the picture comes from the network) 1 The morphological characteristics of diatoms: single cells of plants, or groups of cells connected with each other into chains, belts, clusters and radiations The cells are various and round 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 Coating House News: we all know that diatom mud contains diatomite So, do you know what diatom is? Diatom is a kind of unicellular algae with pigment body, which is often connected into a variety of groups by several or many cell individuals It belongs to the producer in the food chain, and is mainly characterized by the cell wall covered with siliceous substance (mainly silica) outside the diatom cell Fossil remains show that diatom originated in the early Jurassic at the latest Diatoms (the picture comes from the network) 1 The morphological characteristics of diatoms: single cells of plants, or groups of cells connected with each other into chains, belts, clusters and radiations The cells are various in shape, from round, elliptical to lanceolate, with a few species expanding in the middle of the two sides, or in symmetrical waves It usually grows by floating or attaching to other rocks and other objects, and the living species usually have a colloidal handle or are enclosed in colloidal mass or tube The algae are orange yellow and yellow brown The cell wall of diatom is covered with silicon (mainly silicon dioxide), and there are a lot of pores on the cell wall, which make it have both small mass and strong structure 2、 The geographical distribution of diatoms diatoms are the most important phytoplankton, which are widely distributed, and can be found in the ocean, fresh water, soda water, soil and wet surface Most of them live in open ocean waters Of course, some of them live on the sea floor gravel like a membrane, and some of them can survive in only humid atmosphere Some species of diatoms can even be found at an altitude of 2km In the world ocean, wherever there is water, there are generally traces of diatoms, especially in the temperate and tropical sea areas Because there are many kinds and large quantities of diatom, it is called the "Grassland" of the ocean 3、 The growth and propagation of diatoms diatoms, which synthesize the inorganic matters in the sea water into the organic matters needed by themselves by photosynthesis, belong to autotrophic organisms Reproductive methods include sexual reproduction and nutritional reproduction, in which nutritional reproduction is the main mode of reproduction In a suitable environment, the propagation speed is quite fast, if not handled properly, red tide will form Red tide: if the water environment is polluted by eutrophication or other reasons, some diatoms, such as skeletonella and rhombus algae, are often overproduced, resulting in red tide, which causes poor water quality and serious harm to fisheries and other aquatic animals Some diatoms (such as Rhizopus) reproduce too much and gather together, which can hinder or change the migration route of herring and reduce the catch Because of this, diatom, as an important indicator species of environmental monitoring, has been used in water quality research 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,
