Conclusion: the project is in line with “high performance water reducer” index of GB8076-2008.

Dosage and usage

1.For powder NZY-P, the dosage is typically 0.2%~0.6%, 0.8% for high strength concrete.

2.The amount of NZY-P used in concrete will be slightly adjusted depending upon job requirements, such as concrete strength, variations in cement, aggregate and other job site conditions. Experiments for appropriate dosage must be carried out when changing concrete mix proportion or materials.

3. NZY-P can be added in concrete with other raw materials directly.,and it is much better to dilute as solution which contains solid before using it.

4. NZY-P cannot be used with naphthalene based water reducing admixture.

5. Experiment must be done when NZY-P is used together with other admixtures.

Packaging, Transport and Storage

1. Powder NZY-P is available in 25kg film-lined bags. Other special package can also be available according to prior consultation.

2. Special measures should be taken to ensure entire package.

3. Dry and well ventilated warehouse is needed for storage. Quality guarantee of NZY-P is one year under normal conditions. If storage has surpassed the time, test must be done to confirm the validity.

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:What's the additive inverse of -3.?
I've just answered a similar question about additive inverse and absolute value. I'm posting the Q and my A below: Q What is the difference between the additive inverse of a number and its absolute value? My A. The additive inverse of a number is what you must add to that number to get a total of zero. eg. The additive inverse of 6 is -6, since we have to add -6 to 6 to get zero. Another example: The additive inverse of -3 is 3, since we have to add 3 to -3 to get zero. Another example: The additive inverse of 0 is 0, because 0 is the only number that can be added to 0 to get zero. As you can see, to get the additive inverse, just reverse the sign (+ to - ..or.. - to +) The absolute value of a number is that same number, but with its negative sign removed if it had one. examples: Absolute value of 6 is 6 Absolute value of -13 is 13 Absolute value of 0 is 0 SO, we can say that:The additive inverse of a number is a number with the same absolute value but opposite sign." I have spoken
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.

Essential production resources (a) production sites. Plant design is reasonable, there should be with the production of raw materials to adapt to the library, processing workshops, finished products, packaging workshop, the production of fermented soybean products enterprises should have the appropriate fermentation sites. Processing workshop must have a good ventilation, packaging workshop should be sealed with disinfection measures, production sites should be separated from the living area. (2) the necessary production equipment. (Such as cooking cans, etc.); 2. Pulping equipment (such as grouting machine, cooking pulp tank, etc.); 3. Cooking equipment (such as cooking cans, etc.); 4. Molding equipment (such as cutting machine, Presses, etc.); 5. Fermentation facilities (such as fermentation cages, drawers, etc.); 6. Drying facilities (such as dryers, etc.); 7. Packaging facilities (such as packaging machines, etc.). In addition to the above equipment, the production enterprises according to their different production processes, must have its corresponding production equipment and facilities. Such as sterilization, frying and other related equipment. Fermented bean milk production enterprises must produce equipment: 1,2,4,5,7. Tempeh, natto production enterprises must produce equipment: 1,3,5,7. Soy milk, lactone tofu and other production enterprises must produce equipment: 1,2,7. Tofu, dried tofu and other production enterprises must produce equipment: 1,2,4,7. Yuba production enterprises must produce equipment: 1,2,4,6,7. (Packaging enterprises must produce equipment: 7.) fried and other soy products production enterprises must produce equipment: 1,2,4,7. (Purchased bean sprouts essential production equipment for enterprises: 7)

The chemical properties of butanone and acetone are very similar. Butanone: colorless liquid. A melting point of -86.3 ° C, a boiling point of 79.6 ° C and a relative density of 0.8054 (20/4 ° C). Dissolved in about 4 times the water, soluble in ethanol, ether and other organic solvents. And water to form a constant boiling point mixture (containing butanone 88.7%), the boiling point of 73.4 ℃. Steam and air to form an explosive mixture, the explosion limit of 2.0% to 12.0% (volume). The chemical properties are similar to acetone.
