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:If the wrong type of oil was put in the toyota prius, well that harm the car?
An additive won't void the warranty, but it won't do any good either. Not one aftermarket additive has been shown to help regardless of any anecdotes, celebrity endorsements, or late night TV shows you may have seen or heard. Instead buy the best oil you can. You can tell the best oils because they meet both ACEA A5/B5 and ILSAC GF5 standards. It will say so on the bottle. Putting in the wrong oil can harm the engine although it depends on the circumstances. If the oil is too thin, then it may not lubricate properly at higher temperatures. If too thick it may not lubricate properly at low temperatures. Your 2008 Prius uses 5W-30 which is commonly available so there should never be any reason to put in the wrong oil. If you overfill the oil (oil is over the overfill mark on the dipstick) you can harm the O2 sensors. Some people say that you get less mpg. The best plan is to have the oil level at about 1/4 inch below the overfill mark.
Q:I found this site - www.oneinmillion.ws/ecomates.htm I want to join them but not sure if the product actually do what they say they do.
sounds like any other additive ive seen and heard of. i actually tell our customers to stay away from additives. waste of money and if n e thing the difference is so small youll never notice it.
Q:7 what is the additive inverse and what is the absolute value?
additive inverse of 7 is -7 absolute value of 7 is 7
Q:What is the major disadvantage of putting additives into food?10 points
Preservation - food last longer (e.g. doesn't spoil as fast). Enhances flavor - makes food taste better or in the case of meats more tender. Disadvantages: Some food additives aren't safe and may cause diseases (e.g. sodium nitrates in bacon).
Q:?!?!?!?
Let x additive inverse. -8 - 5i + x 0 x 8 + 5i
Q:seriously i had it written down but i lost that paper, can somebody please explain it to me?
The additive identity is the matrix that you can add to any matrix without changing it. This will always be the appropriate sized matrix (in this case, 2x4) where every entry is 0.
Q:Does the feed additive report the same as the veterinary drug?
New feed and new feed additives management approach requires the need to verify the other feed additives:
Q:Please could someone help me with my school project, the question is:Suggest three possible strategies to address the issue regarding food additives. Think about how consumers should be informed about the uses of additives and the possible influence of food additives, colorants and chemical preservatives on health (possible allergic reactions)All help would be greatly appreciated!!
Yes, food allergies can definitely create your sensations. Sorry your preferred MD is not aware of other consequences of allergic reaction. Glad you know how it manifests in animals and have made the correlation. Recently, I have determined an allergic reaction to the milk products I have been consuming had created the skin condition I've dealt with for over 7 years with no MD helping me figure it out (thanks Kaiser Permanente - not!). So, by eliminating the milks, my liver calmed down, and voila - no more itching and other unpleasant skin eruptions. No need to put topical steroids on to handle the itching. You are correct an elimination diet can determine what you have become allergic to. Sounds like you've got some info on how to go about that and know it will take time. If you've had lots of antibiotics prescribed in your life, there could be a Candida issue. A diet outline for resolving that is listed at the website below. I am sure there are other outlines available on the web but this one lists what a friend had to do over 20 years ago. If you are willing to step away from Western medical practitioners, and have access to alternatives, you can seek Acupuncturists, Natuopaths and certified herbalists for their assistance in solving your health riddle. Good luck with your detective work. Thanks for asking for input from strangers here on Yahoo. May you get relief shortly! Maluhia - peace.
Q:I‘m getting 20-some miles per gallon, but the prices at the pump really hurt.
Well, I won't make that an absolute no. It depends on how old your car is. If you own a car that was built in the last 15 years or so, it has programmed fuel injection. A computer monitors a number of sensors located at various points in your intake system, the engine itself, and the exhaust. The computer knows when the engine is cold, and delivers the extra fuel it needs to warm up. When the engine is at operating temperature, it monitors the amount of oxygen in the exhaust gas to adjust the air/fuel ratio to its ideal proportions. This is called the stoichiometric ratio. For a gasoline engine, this is 14.7 parts of air for each part of fuel, by weight, and the computer adjusts fuel delivery to maintain this ratio. No fuel additive will have any real effect on it. The stoichiometric ratio for different types of fuels varies, but when you consider how these things are sold - in 8-oz bottles, for example, anything you'd add like this would have a negligible effect on the composition of what's in a 12 to 20 gallon tank. This being said, there are some fuel additives that can help to clean injectors that have gotten fouled with age. This will make them work better, and might save you some gas. However, if your injectors are fouled, it's probably time for a general tune-up. Finally - your gas mileage will vary with the kind of driving you do. Slow down, if you can, or take a different route to work, or leave at a different time, to avoid some of the stop and go traffic that kills gas mileage.
Q:I know in 2008 they removed this claim from the package so now I am not sure. Is it still additive free tobacco in these cigarettes?I know that they are FSM so have to have some chemicals in the paper but I‘m talking to actually tobacco.
They removed it because no cigarettes can claim to be additive free. Seriously, they've all been proven to be just as bad for you as any other cigarette (this is why they've also removed the light ultralight distinction). Unless you're a complete idiot, you know this already or you're just in denial--and let's face it, these days you pretty much have to remain in constant denial to remain a smokerbut I get it. You might as well be a healthy smoker right? I'm sorry this sounds so preachybut if you're truly concerned about the additives than you might consider switching to an e-cig or something. If you're interested in quitting, maybe check out Allen Carr's The Easy Way to Stop Smoking.
