Product Description:

Ⅰ . Product Description:

NZY-SR retarded type water reducer is composed of high performance and high efficiency water reducer and retarded components, slump retention components, as well as other functional components, with high performance of water reducing, slow slump loss and Concrete hydration temperature rise.

NZY-SR can effectively inhibit the concrete early hydration and without affect the later strength, is ideal concrete admixture for high performance concrete, mass concrete and long-distance transport concrete products.

NZY-SR retarded type water reducer has both liquid and solid package.

Ⅱ. Main technical features

(1) A kind of polyhydroxy organic compound, non-toxic, odorless, non-flammable, and free steel-corrosion effect.

(2) Extend setting time, reduce mixing water (5%-30% water saving).

(3) Extend induction period of cement hydration, slow down hydration rate, delay cement hydration exothermic process.

(4) Improve workability, easy to pour and vibrate.

(5) Increase strength, reduce cement content.

. Applications

NZY-SR retarder is used in reinforced concrete, prestressed concrete, mass concrete, pump concrete, road concrete, and waterproof concrete construction projects which require extension of setting time.

NZY-SR retarder is suit for concrete construction in summer or hot weather.

NZY-SR retarder can be used in slip-form concrete construction.

NZY-SR retarder can be used as supplementary materials for produce or remix other concrete admixtures.

Ⅳ. Packaging, transport and storage

(1) Powder retarder is available in 25±0.25kg film-lined bags. Liquid t retarder is available in sealed 200kg or 1000kg bucket. Other special package can also be available according to prior consultation.

(2) Special measures should be taken to ensure entire package. Keep waterproof during transportation.

(3) Dry and well ventilated warehouse is needed for storage. Quality guarantee of retarder is two years under normal conditions. If storage has surpassed the time, test must be done to confirm the validity.

Ⅴ. Health and safety

(1) Once splashed into eyes and skin, wash immediately with plenty of water and seek medical treatment.

(2) Inedible. When eating by mistake, drink sufficient water to urge to vomiting, and then go to hospital.

(3) No littering. Caution should be taken to protect environment.

Q:The state expressly prohibits the addition of food additives
The state expressly prohibits the addition of food in the food can not be called food additives, and is generally referred to as illegal additives. Our country's Ministry of Health has repeatedly published in the food may be illegal to add non-food blacklist, there are hanging white block, Sudan red, Wang Jinhuang, melamine, borax, sodium thiocyanate, rose red B, art green, White, acid orange, formaldehyde, industrial caustic soda, carbon monoxide, sodium sulfide, industrial sulfur, industrial dyes, poppy shell, leather hydrolyzate, potassium bromate, benzoyl peroxide, dimethyl fumarate, waste oil, mineral oil , Industrial gelatin, industrial alcohol, dichlorvos, hair water, industrial acetic acid, sorbic acid, copper sulfate, nitrofurans, clenbuterol, sedatives, industrial magnesium chloride, chloramphenicol, water glass, malachite green, Care products, sodium pentachlorophenolate, alkaline yellow, trichlorfon, olaquindox and so on. In addition, the use of food additives and over-range is also illegal.
Q:What are the common food additives
Common chemical additives are preservatives sorbic acid, colorant caramel color, sour agent citric acid, lactic acid, etc. In fact, these chemical additives have a scientific name and common name of the points, of course, is the use of common name. Now the public because there is a smell of preservatives and discoloration of the psychological, so businesses in the food recipe to write its common name is also promising. We have to oppose the intentional speculation of some businesses, such as a moon cake packaging marked with a line of words: "This product will not contain preservatives," there can be a line below the small word "sodium benzoate", but in its There are sorbic acid in the formula. It is not without preservatives, but does not contain preservative sodium benzoate, the same is still a preservative. This is the intention of business speculation. As well as some vegetable oil manufacturers in their products marked "this product will not contain cholesterol", in fact, all the vegetable oil is not cholesterol. They want to advertise can write "vegetable oil does not contain cholesterol", but they write "this product will not contain cholesterol" to give people an illusion that only their products do not contain cholesterol, and other vegetable oil contains cholesterol. These are businesses deliberately speculation.
Q:Explain how a colour monitor makes use of additive colour theory to create a colour image?
Additive color theory is generating a mix of with emitted light as opposed to subtractive color which is mixing colors by reflecting light. The customary additive colors are red, green and blue, which are chosen to represent a range of colors that fool the color receptors in the eye into perceiving all possible mixes of colors. An example the customary R G B color set doesn't include any yellow, but the combination of red and green stimulates the eyes sensors in the same way that true yellow light would.
Q:Do you need to add additives to the new car?
Before buying and using fuel additives, be sure to see the function and use of the product, do not think that all the additives are a function can be added at random, resulting in unnecessary waste, more serious may also affect the normal engine jobs.
Q:Can food additives be eaten directly? why?
Can not but believe you eat try ``
Q:The animaniacs do a song about food additives. where can i find the lyrics for that song?
Animaniacs Friendship Song
Q:additive and multiplicative inverse?
Inverse means opposite. Keep that in mind. The additive inverse of a given number is the number that you can ADD to it to get 0. The additive inverse of 5, for example, is -5 because 5 + -5 = 0. The multiplicative inverse of a given number is the number that can be MULTIPLIED by it to get 1. Another word for multiplicative inverse is reciprocal. The mult. inverse of 5 is 1/5 because 5/1 * 1/5 = 5/5 or 1. In your first example, I recommend that you write .4 as a fraction. .4 = 4/10 4/10 + -4/10 = 0 So, -4/10 is the additive inverse of 4/10 4/10 * 10/4 = 1 So, 10/4 is the multiplicative inverse of 4/10. Now you try! Can you do -11/16?
Q:Food additive formula
Q:How much is the amount of sodium nitrite food additive?
National standard "GB 2760-2007 hygienic standard for the use of food additives" on the provisions of nitrite: sodium nitrite, potassium nitrite food classification of food name / classification maximum use of g / kg
Q:What are the provisions of the law on food additives
National standards are "national standards for food safety food additives use standards"
