Use: This product is mainly used as main raw material of cementconcrete admixture and can be

prepared to concrete antifreeze, rebar corrosioninhibitor, early strength agent, etc. This product can

also be used in heavyoil washing, lubricating oil emulsification, chemical organic synthesis andother

fields.

1. Antifreeze: Can reduce the freezing point of themixing concrete. Construction temperature can be

down to -25 °C. Negativetemperature can promote the hydration of mineral components in cement. It is a new generation of low-alkali chlorine-free antifreeze.

2. Rebar corrosion inhibitor: It has excellentpassivation, rust resistance and protection effects.

Adding 2-3% calciumnitrite can prolong the life of buildings and structures for 20-50 years.

3. Can prepare early strength agent to improve concretestrength, reduce cement consumption and

shorten construction period.

This product fundamentally overcomes the defects ofconcrete alkali aggregate reaction and

electrochemical corrosion, improves thephysical and mechanical properties and durability of concrete

to get highquality concrete.

Calcium nitrite inorganic salt

Packing: 25/40kg woven bag lined with plastic or according tocustomer requirements.

Q: Inorganic salts play an important role in maintaining the life activities of living organisms. It is mainly in the form of living organisms.: Inorganic salts are mineral nutrients present in the body and in the food. Most inorganic salts in the cells are present in the form of ions, consisting of organic matter and inorganic compounds.

Q: Are plants absorbing water and inorganic salts only through root tip or wrong? The: Plants through the leaves can also absorb water and inorganic salts, but the root tip is the main part of the plant to absorb water and inorganic salts.

Q: How much of the body's inorganic salts account for the weight of the body?: The inorganic salts in the human body account for about 5%

Q: Inorganic salt function: The various inorganic salts dissolved in the cells have a certain total concentration, such as human body fluid concentration of 0.9%, frogs of 0.65%, which for maintaining cell osmotic pressure, so that cells maintain a certain shape has an important role, too high or Too low will lead to cell due to water or dehydration to change the cell morphology. There are also a number of buffering systems in the body, which are a group which has a neutralizing effect on the added acid or base so that the pH does not change significantly and therefore plays an important role in maintaining the acid-base balance of the cells.

Q: I had asked a similar question on GC operation last week, but for different kinds of compounds.For my biochem research project at school, I&#39;m testing the ability of a species of bacteria to biodegrade alcohols found in gasoline (methanol, ethanol, isopropyl, tert-butyl and cyclohexanol). The bacteria is growing in a solution of minute amounts of alcohols and Mineral Medium, which is basically just water and dissolved inorganic salts (CaCl2, KH2PO4, NH4NO3 and MgSO4).I know GC&#39;s are primarily used to separate organic mixtures. Can a GC separate organic compounds dissolved in salt water? Is it safe to put salt water in a GC? Or would I have to do an extraction to separate the alcohols and run the organic extract through the GC?: Do not let salts enter the GC. You will have to perform an extraction step and run that. Salts can precipitate in the column or degrade into reactive species that can corrode the GC. Water is OK since it will not destroy the column (I've run aqueous solutions before), but salts are not.

Q: The inorganic salt is composed of?: Inorganic salts are the general term for various inorganic salts. They are composed of inorganic acid radicals and metal cations or ammonium salts, mainly salts of organic acid salts, such as sodium chloride, potassium chloride and so on.

Q: What does salt form when it dissolves?: ions. depending on which kind of salt: NaCl -> Na+ + Cl-

Q: A. oxygen demanding wastesB. organic plant nutrientsC. inorganic plant nutrientsD. water soluble inorganic chemicalsE. sediment: Acids, D. water soluble inorganic chemicals salts, D. water soluble inorganic chemicals metals E. sediment

Q: As if there are two kinds of nitrogen, phosphorus and potassium, hoping to get answers and explain their respective roles: Only 70 kinds of chemical elements can be detected in plants, but only 16 kinds of essential nutrient elements are needed for the growth and development of internationally recognized higher plants. They are carbon (C), hydrogen (H), oxygen (O), nitrogen (Fe), magnesium (Mg), sulfur (S), iron (Fe), boron (B), manganese (Mn), copper (Cu), zinc (Zn), molybdenum (Mo) and chlorine (C1), which can be divided into large nutrient elements, medium nutrient elements and micronutrient elements according to their requirements, such as carbon, hydrogen, oxygen and nitrogen Phosphorus, potassium, copper, zinc, molybdenum and chlorine.Now there are scholars that nickel (Ni) is the first 17 kinds of essential nutrients.

Q: Inorganic salt is not salty: HCl (hydrochloric acid) dilute: more acid, feeling slippery mouth, the typical vomit feeling, slightly spicy. Concentration: extreme acid, spit after the bitter taste, and then the whole mouth cold, 10 minutes later improved.
