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: this is a maths problem
- I wouldn't say justify is an accurate choice of words. Support is more like it. In fact additive inverses are defined this way. Anyway 1 + (-1) 0 . 4 + (-4) 0
- Q: Is it safe to use and store gas with ethanol in lawnmowers, tillers and trimmers with additive added?
- That is all figured into the price. It might be hard to find gas that does not contain some ethanol at this point. Ethanol added to gas will not significantly reduce the cost of the product at the pump.
- Q: why overusing of food additives is prevalent in some countries?
- Preservative Food consistency (prevent separation of liquid solids; make something creamier) Cheaper (calcium carbonate chalk, in lots of foods) Taste (does sugar REALLY need to be in peanut butter? no) Faux-health (but cereal has all these vitamins and minerals!)
- Q: what is a nutrient additive and what is an example of one?
- there are a variety of nutrient additives, its essential function is to speed a plant up, making the plant work faster and harder. These hormones help the plant to have more energy, grow faster, and ultimately, to produce more. ex. Sweetleaf - is a great additive which includes molasses, cane sugar, a full suite of B-Vatamins, esters, and polyphenolic copounds that come together to greatly increase flavor, aroma, and overall oil content in your favorite fruits and flowers.
- Q: I just read an article about food additives and just how bad they are for your body.My question is this These days is it possible to eat truly healthy? And if so, how?!?!?! By never going to the grocery store?
- It depends on the source of the fire and the type of fire extinguisher. There are 4 classes of fire A - Standard combustable like paper and wood B - Liquids like oil and gas C - Electrical D - Metals (Magnesium, etc.) (Generally the only way to put out is to smother) Fire extinguishers are classified by what type of fire they can be used on. The main types are Water - used on type A CO2, halon, (displacing gasses) - used on types A and C, can be used on type B to some effect AFFF (or similar agent) - used on type B, can also be used on type A PKP (or similar chemical agent) - used on types A, B, and C (D?) Generally there are three things that make a fire burn.fuel, heat, oxygen. Take away one of them and the fire will go out (at least until it is reintroduced). Water takes out heat. CO2, AFFF, etc. are used to deprive fire of oxygen PKP - can't really explain the chemical reaction that takes place, but it works.
- Q: I smoke a brand that says that it does not contain any unnecessary additives in it, now I know that this means it‘s not a safe cigarette but what does No additive or hardly any additives mean in a cigarette? Like does it mean it would be easier on your lungs or something? Please help me out people, thanks )
- It just means that the cigarettes aren't sprayed down with additives like formaldehyde and heavy metals to make them burn slower. Though in theory this is a good thing, it won't save you from health problems. In face, tobacco in its natural state contains carcinogenic and otherwise harmful chemicals. I'm definitely not trying to lecture you, if you're an adult you have ever right to choose to smoke, but it'd be like drinking organic rat poison, it's still toxic and chances are, you're probably still going to get sick. Cool little factoid, only something like 20% of smokers get lung cancer, most people who smoke end up with other sorts of lung problems and heart/cardiovascular disease insteadnot that it has to do with the topic, just thought it was an interesting little excerpt.
- Q: what is an additive inverse?
- An additive inverse is a number that when added to another equals 0
- Q: What is the additive inverse of 4i?
- you can use fix a flat but it sounds like it might be leaking around the rim or the valve stem is leaking !
- Q: The percentage of food additive usage is relative to what
- Generally expressed in mg / kg. Ie how many additives are added to 1 kg of food
- Q: What is good for fattening pig fertilizers?
- , Fattening pig fattening, especially late is very critical. Weight gain weight, pure green additive, late weight gain, long three pounds. Increase feed intake, advance slaughter, improve pig weight. Henan Beiweiwei Biology Branch ji.
