Silicon Dioxide, E551, CAS no.7631-86-9, white powder. Silicon dioxide (SiO2), also known as silica, is a natural compound made of two of the earth's most abundant materials: silicon (Si) and oxygen (O2). Silicon Dioxide is a common additive in the production of foods, where it is used primarily as a flow agent in powdered foods, or to absorb water in hygroscopic applications used in silica gel, control moisture levels to avoid prevent certain goods from going bad. It is often used in cheese, fat spreads, confectionery, dried vegetables, etc. As an experienced Silicon Dioxide manufacturer and supplier, we has been supplying and exporting Silicon Dioxide for almost 10 years, please be assured to buy from us.

An oxide is a chemical compound that contains at least one oxygen atom and one other element in its chemical formula. "Oxide" itself is the dianion of oxygen, an O2 atom. Metal oxides thus typically contain an anion of oxygen nitrous oxide zinc oxide magnesium oxide iron oxide aluminum oxide cerium oxide red oxide copper oxide lead oxide calcium oxide graphene oxide scandium oxide ethylene oxide nickel oxide propylene oxide molybdenum oxid tin oxide silver oxide Origins: iron,germany,india,australia

Ball mill for lead oxide is a basic device in the modern world of metallurgy and is extensively used in a variety of applications. Among others, it's applications in the processing of non-ferrous metals is one of the most important. In the field of lead processing, dry type ball mills are used for conversion of lead pellets into fine lead oxide powder (lead oxide free lead), also commonly called grey oxide due to its appearance. The ball mill with its preparatory and collecting equipments is therefore also called a grey oxide plant. Description of process: Lead is melt in a melting pot and cast into pellets (hemispherical or cylindrical shape) at a ball making machine and fed into the ball mill. The ball mill is rotated on its own axis at low speeds. The rotation of the mill imparts tumbling & cascading action to the balls fed (in this case the lead pellets). The rotation is adjusted so that the raw material inside does not reach critical speed. Below the critical speed (at around 65 - 75%), the balls which are carried along the walls of the mill fall back to the center. This continuous action leads to friction and generation of heat which induces the reaction of lead (pb) with oxygen (o2) present in air and generation of lead oxide (2pbo). This reaction is an exothermic reaction which leads to generation of heat and this sets of a chain reaction of heat generation and accelerated oxidation process. Draft of air through the mill carries small sized or light particles outside the mill to the collection system. Temperature within the mill is controlled with the help of water spray outside the barrel of the mill. Several crucial characteristics of this produce such as free lead percentage, retention percentage, apparent density are set as per requirements of the client.

Luminol, is a yellow crystal or beige powder at room temperature and is a relatively stable chemical reagent. At the same time, luminol is a strong acid, which has a certain irritating effect on eyes, skin and respiratory tract. It is one of the oldest and most commonly used reagents. It can be oxidized by peroxide under alkaline conditions and emit light at the same time. The redox reaction between luminol and peroxide requires a catalyst, which is generally more Valence metal ions, peroxidases such as iron, horseradish peroxidase, etc. This method is often used to detect the content of peroxides, heavy metals, peroxidase, and the derived free radicals, for toxicant analysis And analysis methods based on peroxidase and glucose oxidase. Under normal circumstances, the chemiluminescence reaction between luminol and hydrogen peroxide is very rapid in the presence of certain catalysts. The most commonly used catalyst is metal ions. In a large concentration range, the concentration of metal ions is directly proportional to the luminescence intensity, so that chemiluminescence analysis of certain metal ions can be performed. This reaction can be used to analyze organic compounds containing metal ions to achieve Very high sensitivity. The second is to use the inhibitory effect of organic compounds on the chemiluminescence reaction of luminol to determine the organic compounds that have a quenching effect on the chemiluminescence reaction. The third is the indirect determination of inorganic or organic compounds through coupling reactions. Luminol Luminescence Principle One is that sodium hypochlorite oxidizes luminol to make it glow; The second is that hydrogen peroxide reacts with sodium hypochlorite to generate oxygen and oxidize luminol to make it glow: The first is the equation for the reaction of sodium hypochlorite and hydrogen peroxide: NaClO+ H2O2== NaCl + O2+ H2O Secondly, when luminol reacts with hydroxide, a double negative ion (Dianion) is formed, which can be oxidized by oxygen generated by the decomposition of hydrogen peroxide, and the product is an organic peroxide. The peroxide is very unstable and immediately decomposes nitrogen (Luminol is not oxidized by organic oxidants such as dimethyl sulfoxide to generate nitrogen, but to generate nitrogen-containing organics) to generate excited 3-aminophthalic acid . In the transition from the excited state to the ground state, the released energy exists in the form of photons with a wavelength in the blue part of visible light. The method of indirect determination by coupling refers to the combination of one reaction that can produce or consume chemiluminescence reactants with another chemiluminescence reaction, so that indirect chemiluminescence determination of certain substances can be achieved. This method is used when determining the purity of certain substrate enzymes.
