Product introduction：
Polyanionic Cellulose referred to as PAC, is made from natural cellulose by chemical modification and the obtained water-soluble cellulose ether derivatives, is an important water-soluble cellulose ether, its sodium salt is usually applied. Polyanionic Cellulose has good heat stability and salt tolerance, anti-bacterial and strong. The product is prepared with a good drop of fluid mud water loss, inhibition, higher temperature resistance. Widely used in oil drilling, especially offshore oil drilling wells and salt water.

- Q: I ment -.4 instead of 1.4
- Additive inverse of 0.4 is -0.4, multiplicative inverse is 1/0.4 = 1.5. Additive inverse of -1.6 is 1.6, multiplicative inverse is 1/1.6 = 0.625 Additive inverse of 5 5/6 is -5 5/6, multiplicative inverse is 1/(5 5/6) = 1 /(35/6) = 6/35. (Do you see the pattern?) I hope that helps!
- Q: Do teflon based engine oil additives such as Nulon actually work or are they just a marketing gimmick?
- DO NOT USE THEM! Oil Additives Do not use any oil additives no matter how much they are hyped on TV. They provide no benefit and can interfere and react with the additives already present in the oil. Some additives have particles that can clog oil passages and clog filters. Common additives that are heavily hyped are Slick 50, Duralube, and Prolong. Return to Table of Contents
- Q: that are still allowed.
- Corn syrup Hydrogenated oils
- Q: find out 3 food additives from labels of 3 different foods and explain the purpose of each additive?
- A new one from Ford is 61.98 but there is one available aftermarket(Napa, Autozone etc. ) for less but quality will be less. The junkyard may be an option but I would advise against it as the arms weaken over time and it may be only a temporary fix.
- Q: I‘ve not found a good additive for my truck to remove moisture(water) that I‘ve been told by many that is causing havoc with my motor.
- Submarines, hospitals and chemical companies have been doing this for years. It takes a whole lot of DC power to shock pure water, which separates it into hydrogen and oxygen. Basically, you have a nickel cadmium cylinder with a anode (negative) and a cathode (positive) side. Inside there is usually a teflon sleeve to keep the two separated after electrolysis. If they join together, the would spontaneously explode. Which is how the shuttle gets to the moon. The cathode draws the negatively charged oxygen and the anode draws the positively charged hydrogen Thus resulting in the two separate gases. The machines that accomplishes this is very complicated, with numerous gas analyzers, leak detectors and safety mechanisms. Also, these machines have to be monitored virtually 24/7 and cannot be monitored and maintained through just a few simple car gages. Also, the water has to be pure. Any impurities whatsoever could cause an explosion. So, be very careful when playing with this stuff. The problem with this technology, as stated before is that you expend far more energy to separate these two gases, than you could produce by their burning At least with today's technology. It would be very nice to run off of water but also very dangerous and probably not worth the expense, considering the hazards involved. Did I mention the space shuttle?
- Q: Are women organic, or do they have artificial additives?
- I used to go clubbing and there were many artificially enhanced women there. But then, so were a lot of the guys.
- Q: China's first brand of fuel additives which is
- Leqi fuel additive is detected by the National Ministry of Communications, the national second five energy-saving emission reduction products, has been the national patent, the product is a biological agent, the engine without any corrosion.
- Q: Is the water treatment additive a chemical raw material?
- Surely it is flocculant or coagulant.
- Q: Make noodles add any additives
- The additive added to the noodle is JINLIYUAN? (F).
- Q: i am doing a project on food additives and i need to know some pros. Also if you have any other useful facts about additives.
- It entirely depends on the additive of course, and while I am generally against additives, there are a few different reasons they are used. 1. To attempt to make the food taste better (i.e. MSG) 2. To make the product last longer at the store (less turnovermore money) 3. To stretch the product. Sometimes using additives is less expensive because it makes more product at a cheaper production rate. Hope this helps.
