Calcium Nitrite for Cement Concrete Admixtures

Molecular formula: Ca(NO2)2

Molecular weight: 132

Properties:

Calcium ammonium nitrate is white or grey granular which dissolves in water absolutely.

It is a new type high-efficient compound fertilizer.Suitable both for straight application and blending.

Property and main advantage:

It contains nitrogen and calcium,and also supplies nitrogen to plant quickly, nitric nitrogen not needed to be transferred.

It is a neutral fertilizer and can improve the quality of soil.

It can lengthen the florescence,promote the root,stem,leaf to grow normally.

Ensuring the color of the fruit is bright and the fruit candy can be increased.

Technical standard: Q142401/CSC-01-2000

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.

FAQ

1.Q: What is MOQ?

A: Our MOQ is 1 TON.

2.Q: Could you offer free sample?

A: We can provide free samples to you for quality testing.

3.Q: What about your packing?

A: For liquid: Flexitank, or IBC tank 1000L

For powder:Woven fabric bag with plastic film liner( 25kg or 1000kg)

Clients’ packing is workable.

4.Q: How about your productive capacity?

A: 150000 tons/Year.

5.Q: What is your delivery time?

A: Within 7 days after received deposit or L/C at sight.

Q: The stronger the transpiration is, the faster the absorption rate of inorganic salts and water is: wrong. Can only promote the transport up! Can not promote absorption.

Q: Is it possible to adjust the internal temperature of the carbohydrate in the vacuole: The plant has no internal environment.

Q: How to isolate the effects of inorganic salts on enzyme solubility: The raw materials of cotton stalk were pretreated with inorganic salt to dissolve part of lignin and hemicellulose, so as to improve the enzymatic hydrolysis efficiency. Sulfuric acid, sulfuric acid and sulfuric acid were used to pretreat the cotton stalk. The solid solution was separated and the lignin removal rate and the elution rate of the pentosan were determined. The solid phase was hydrolyzed at 50 ℃. Enzyme hydrolysis conversion rate; the process of glucose, pentosan, lignin for material accounting.

Q: What cells produce the collagen and inorganic salts of bone matrix?: The collagen is produced by chondrocytes. The minerals that make up the bone are precipitated by osteoblasts.

Q: In order to prove that magnesium is an essential salt for soybean life, two soybean seedlings with the same growth status are taken, one of them is cultured in magnesium-containing culture medium and the other is cultured in (). A. Pure water B. Sand without sand. Water containing only magnesium. Media containing no magnesium: Biological control experiments were the only variable experiments. The question that is being explored is the variable, and the other quantities are the same. In a different amount (conditions) the same circumstances to modify a data variable in order to get the data variables on the experimental changes in the law. In order to prove that magnesium is essential for the life of soybeans, the variable is the presence or absence of magnesium. Can be designed as a magnesium-containing culture medium and magnesium-free culture medium. The other amount of the same as the amount of culture medium, soybean seedling growth status, the same number, while placed in the same place, etc., to ensure that only one variable that is the presence of magnesium.

Q: What is the lack of inorganic salts for children?: Children in the rapid development of the physical stage of the body, zinc consumption is very large, add must keep up, eat more fish and eggs, but not excessive.

Q: Think about the physical and chemical properties of salt and sugar. What properties do these substances have in common? Describe which properties you could use to distinguish between them. What properties and units would you use to describe their physical and chemical characteristics? List as many as you can.: Salt: inorganic, ionic bond, soluble in water (ionizes); forms a crystal lattice structure as a solid. Sugar: organic compound, mostly covalent bonds, also soluble in water but does not ionize, can be burned, tastes good (just kidding).

Q: Of the dissolved salts found in seawater, _____ % are minor inorganic salts, or trace.: it's definitly one of these: 99.28 .72 72 50 i think it's 99.28. lemme no if you get it right!!

Q: What are the effects of water, inorganic salts, carbohydrates, proteins, fats and vitamins?: The main physiological function of fat: 1. The supply of human heat. (Per gram of fat oxidation can produce 9 kcal of calories, protein and carbohydrates produce more than 2 times.) 2. constitute the body's adipose tissue, adjustable body temperature, To prevent the body outside the scattered, to protect the internal organs, moisturizing the skin. 3. Dissolve nutrients. (Some do not dissolve in water and only soluble in lipids, only in the presence of fat can be absorbed by the body.
