Calcium carbonate is a chemical compound with the chemical formula CaCO . It is a common substance found in rocks as the minerals calcite and aragonite and is the main component of eggshells, gastropod shells, shellfish skeletons and pearls. Formula: CaCO3 Molar mass: 100.0869 g/mol IUPAC ID: Calcium carbonate Density: 2.71 g/cm Melting point: 825 C ChemSpider ID: 9708
Boric acid, also called hydrogen borate, boracic acid, and orthoboric acid is a weak, monobasic Lewis acid of boron. However, some of its behaviour towards some chemical reactions suggest it to be tribasic acid in the Br nsted sense as well. Boric acid is often used as an antiseptic, insecticide, flame retardant, neutron absorber, or precursor to other chemical compounds. It has the chemical formula H3BO3 (sometimes written B(OH)3), and exists in the form of colorless crystals or a white powder that dissolves in water. When occurring as a mineral, it is called sassolite.
Antimony Oxide is the inorganic compound with the formula Sb2O3. It is the most important commercial compound of antimony. It is found in nature as the minerals valentinite and senarmontite. Like most polymeric oxides, Sb2O3 dissolves in aqueous solutions with hydrolysis. A mixed arsenic-antimony oxide occurs in the nature as the very rare mineral stibioclaudetite
Ammonium polyphosphate is an inorganic salt of polyphosphoric acid and ammonia containing both chains and possibly branching. Its chemical formula is [NH4 PO3]n(OH)2 showing that each monomer consists of an orthophosphate radical of a phosphorus atom with three oxygens and one negative charge neutralized by an ammonium cation leaving two bonds free to polymerize. In the branched cases some monomers are missing the ammonium anion and instead link to three other monomers. The properties of ammonium polyphosphate depend on the number of monomers in each molecule and to a degree on how often it branches. Shorter chains (n1000),[1] but short polymer chains (e.g. pyro-, tripoly-, and tetrapoly-) are more soluble and show increasing solubility with increasing chain length. Ammonium polyphosphate can be prepared by reacting concentrated phosphoric acid with ammonia. However, iron and aluminum impurities, soluble in concentrated phosphoric acid, form gelatinous precipitates or "sludges" in ammonium polyphosphate at pH between 5 and 7.[3] Other metal impurities such as copper, chromium, magnesium, and zinc form granular precipitates.[4] However, depending on the degree of polymerization, ammonium polyphosphate can act as a chelating agent to keep certain metal ions dissolved in solution.
Ammonium Chloride (NH4Cl),also called sal ammoniac, the salt of ammonia and hydrogen chloride. Its principal uses are as a nitrogen supply in fertilizers and as an electrolyte in dry cells, and it is also extensively employed as a constituent of galvanizing, tinning, and soldering fluxes to remove oxide coatings from metals and thereby improve the adhesion of the solders. It is a component of many proprietary cold medicines and cough remedies because of its efficacy as an expectorant, and in veterinary medicine, it is used to prevent urinary stones in goats, cattle, and sheep. Ammonium chloride is a colourless crystalline substance. It is highly soluble in water, readily forming a slightly acidic solution. It vaporizes without melting at 340 �°C (644 �°F) to form equal volumes of ammonia and hydrogen chloride. Ammonium chloride is yielded as a by-product in the ammonia-soda process for making sodium carbonate. It also is produced by reaction of ammonium sulfate and sodium chloride solutions. When mixed with slaked lime (calcium carbonate), ammonia gas is the result.
A popular seasoning and flavor enhancer, AJI-NO-MOTO , an MSG (monosodium glutamate) product, is the purest form of umami, the fifth taste, altogether different from sweet, salty, sour and bitter. AJI-NO-MOTO is widely used to intensify and enhance umami flavors in sauces, broths, soups and many more foods.
Acetic acid systematically named ethanoic acid is an acidic, colourless liquid and organic compound with the chemical formula CH3COOH (also written as CH3CO2H, C2H4O2, or HC2H3O2). Vinegar is no less than 4% acetic acid by volume, making acetic acid the main component of vinegar apart from water and other trace elements. Acetic acid is the second simplest carboxylic acid (after formic acid). It is an important chemical reagent and industrial chemical, used primarily in the production of cellulose acetate for photographic film, polyvinyl acetate for wood glue, and synthetic fibers and fabrics. In households, diluted acetic acid is often used in descaling agents. In the food industry, acetic acid is controlled by the food additive code E260 as an acidity regulator and as a condiment. In biochemistry, the acetyl group, derived from acetic acid, is fundamental to all forms of life. When bound to coenzyme A, it is central to the metabolism of carbohydrates and fats.

Chemically modified starches contain an E-number; the declaration is Modified starch. Oxidized starch (E1404) is a suitable carrier for food mixtures exhibiting low viscosities after hot preparation. Compared to native starches, acetylated cook-up starches (E1420) are characterized through lower gelatinization temperatures and an improved stability against retrogradation. Regarding heat treatment, acidic conditions and shear forces, di-starch phosphates (E1412) are stable in terms of their viscosity. Acetylated di-starch phosphates (E1414) and adipates (E1422) additionally exhibit excellent freeze-thaw stability as well as clear appearance of the final preparation. Starch sodium octenyl succinate (E1450) exhibits emulsifying properties making it perfectly suitable in the application of oil-in water applications.
The working principle of the hydrogen and oxygen water welding machine is to connect the direct current at the two stages of the electrolysis cell of the water welding machine, so that the water inside the electrolytic cell will undergo an electrochemical reaction to generate hydrogen and oxygen, and then burn with hydrogen as fuel and oxygen as combustion aid. Through the one-way anti-counter-flow valve, wet anti-backburner and dry flame arrester, it will be transported to the hydrogen and oxygen flame gun (built-in dry flame arrester) and ignite to form a precise hydrogen and oxygen flame.
