We specialize in manufacturing FDN-A,B,C of sulphonated naphthalene formaldehyde.Our production capacity is 300,000 tons/year.

SULPHONATED NAPHTHALENE FORMALDEHYDE

1.Product General

FDN-A ,FDN-B,AND FDN-C Superplasticizer is a dry powdered admixture. It is produced through such a process: 1) sulphonating refined naphthalene with sulfuric acid, 2) condensing with formaldehyde, 3) neutralization, and 4) filtering. It conforms to GB8076-1997 and is mainly used for various high-strength concrete, steel concrete, prestressed concrete, large formwork concrete, slipforming concrete etc.

Q:I have an ‘03 Element with 96k miles on it and Ive always taken care of it as far as basic maintenance so Im wondering would it even be necessary to add an additive like a lucas or something??
You might want to add vtec fluid if its 7 years old
Q:what is the additive inverse of -2 + 3i?
the number in the set of real numbers that when added to a given number will yield zero: The additive inverse of 2 is ?2.
Q:How to use food additives properly
Coloring agent (pigment): its role is to show the color of the food or dyed the color we want, the appearance is the most attractive factor, the temptation of the food appearance is easy to make consumers have seen Part of the coloring agent will have some toxicity, when the intake is too large, more than the liver load, will accumulate in the body, the kidneys, liver have some damage.
Q:preferably ones that have the pros and cons but any will do thanks a lot :)
Pedigree, Purina etc are all crap. bypass to a feed keep and purchase grain loose nutrition. I feed my Pit Bulls flavor of The Wild it somewhat is an spectacular nutrition. it somewhat is an all levels nutrition and may well be fed to puppies all a trend to Senior canines. a dash costly yet well worth it
Q:Where there are iron additives
Additives include feed additives, food additives, concrete additives, oil additives and other chemical additives. Harbin Dongsheng Metal Materials Co., Ltd. is a joint-stock high-tech enterprise integrating scientific research, production and sales. The company was founded in 1995. The main products are auxiliary materials for aluminum alloy industry: aluminum alloy additive (iron additive, manganese Additives, chromium additives, copper additives, titanium additives, nickel additives), quick-melt silicon, various intermediate alloys and solvents (covering agent, refining agent, slag agent and No. 2 flux), etc.
Q:I need to research a banned food additive in the Philippines for my General Chemistry course and I have been having trouble finding one. Any form of help will be greatly appreciated, thank you.
Izzy: Doing a research project is NOT asking somebody else to do your work for you. In case you don't know how to do a Google search like this merely look where it has a search bar type in banned food additive in the Philippines Then click Search web. The top website lists 5 the 2nd lists 10 the 3rd lists 15. But you are the one to do the research.
Q:This is a question concerning general chemistry, the property of an ideal solution and a ternary phase diagram. The three mixed liquids were heptane, water and n-propanol, if that helps.
Take them, two at a time, measure the volume of each, mix them, and measure the total volume. If the total volume is the sum of the two, then they are additive. .
Q:based on our experiment, combining 2 mL water 6mL acetone will not gain 8mL liquid
Liquids which are soluble in each other will go into solution when mixed together. Solutions of two liquids Always occupy less space than the sum of both volumes. This is because the act of dissolving species A in species B means that species A will be fitting within the gaps between the molecules of species B. This is going to sound terrible but thats really only partially true. For one example species A ends up fitting 50% of itself between species B's. So it ends up expanding the B-B by 50% of species A size. Thats still less volume that it would have been. If species A and B were each similar volume, then there will be a 25% reduction from the expected additive volume. Species B is ---- B____B____B Species A is ---- A____A____A solutions expectation-B____B____B____A____A____A solution is---B___A___B___A___B___A So you can see the distance between B's actually expands from the just B's liquid, but you still fit more in less space
Q:this is a maths problem
The thing fundamentally wrong with your question is that the additive inverse of a number a is DEFINED as the number b such that a + b 0. You can't possibly hope to justify a definition, you can just illustrate it. eg. The additive inverse of 2 is (-2) as 2 + (-2) 0. The additive inverse of 1/2 is (-1/2) as 1/2 + (-1/2) 0. The additive inverse of 2/5 is (-2/5) as 2/5 + (-2/5) 0. The additive inverse of 1 is (-1) as 1 + (-1) 0.
Q:I have a chemical food additive, that is 1 ounce of chemical to be mixed with 100 pounds of meat. However, I have 7 pounds of meat that is to be mixed, how much of the aforementioned chemical would be added to the 7 pounds?Ex: 100 lbs to 1 ounce 7 pounds to ??? ounce
