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: What is called additive identity of rational numbers?: The additive identity of rational numbers is zero. The way you find it is you ask, A number plus what other number gets me the original number, or x+yx.

Q: I have a 1998 car with 135 thousand miles on it it is suppose to go 0-60 in 9.9sec but it will only do it in 14 and it has some upgrades like a kn cold-air intake so is there anything I can run threw it like sea foam to help restore the engines horsepower: No additive can restore the wear caused by high mileage and jack rabbit starts to time 0-60 acceleration or 1/4 mile times.

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: This came up in my phlebotomy class and the teacher didn‘t really know. It must be an anticoagulant, right?: N is correct about it being Na citrate + dextrose; using packed cells (taking off plasma) removes some of it (it is about 50 ccs per unit of blood currently it is called CPDA-1). If this could be a problem, packed red cells can also be washed, removing all the anticoagulant.

Q: We are becoming more self-sufficient and have gotten into the habbit of making our own bread. The problem we are having is the bread is hard and stale the next day and I want to know if there is an additive I can buy ‘cheaply‘ that will prolong it‘s fresh texture? I‘ve heard of Lecithin but it‘s so expensive. Is there any tips or tricks you can help me with. (store in the refrigerator/wrapping in brown paper/plastic etc I do know about) I want to know what the bakery uses as a quick additive that‘s healthy for you anyone out there that can help?: www ernment-grants .uk/ There is no need to put yourself at risk, there is no need to be without loft-insulation. If you cannot afford to do the job and can prove this, then I would suggest that you go to the web page above, for details.

Q: Virtually all additives are processed to some degree, even fruit juices are concentrated - yet they all stem from something natural originally, whether from plant, animal or mineral.At what point does it become artificial?: I think it is since Mud, Dirt Water is plugging it right now.

Q: The main components of commonly used antioxidants in food additives, as well as the principles of antioxidant?: Deoxidants are also known as free oxygen absorbers, free oxygen scavengers or deoxidizers, etc. It is a substance capable of absorbing oxygen. In the food sealed packaging, while adding the packaging can remove the oxide material, remove the packaging container free oxygen and dissolved oxygen, to prevent food due to oxidation and mold, deterioration and so on. Deoxidizer for food not only can effectively inhibit the deterioration of the quality of the contents, but also to maintain the original food color, smell, taste, pest control, bacterial growth, maintenance of nutrients, extend the preservation time, so the use of deoxidizer preservation Food is a high quality, effective, convenient and safe method of packaging preservation. Deoxidizer is the most commonly used iron series deoxidizer and sulfite deoxidizer. Deoxidation of deoxidizer is based on chemical reactions, so its oxygen removal capacity with the reaction series, time, temperature and other conditions vary. When the quick-acting deoxidizer is present in the sealed packaging container, the free oxygen can be reduced to less than 1% in about one hour and eventually to 0.2%. Slow deoxidation agent takes 12-24 hours, but the final deaeration capacity is the same, free oxygen can be reduced to 0.2% or less. Deoxidizer as a new material for food preservation, has its unique advantages. It is filled with food in the same container, the deoxidizer absorbs oxygen in the container, so that the container was anaerobic state, food can be preserved.

Q: -4x+4x^2-10And show me how you did!Thank you: Let a the additive inverse. a + (-4x + 4x^2 - 10) 0 a 4x - 4x^2 + 10

Q: what are positive and negative things about food additives? and what are more common ones?: salt is probably the most commonly used food additive, with sugar being equal or second in line. Flavor is a positive and unneeded coloring is a definite negative.

Q: what are drug additives? what are things i need to discuss to make the topic drug additives more interesting?: Thimerosol and squalene are two additive/preservatives that have made a lot of people sick and is to blame for the autism increase in children.Squalene can cause a thing called a Cytokine storm.which can be fatal because your body basically turns on itself.
