Product introduction：
HEMC is made from highly pure cotton - cellulose by reaction of etherification under alkaline conditions without any organs of animals, fat and other bioactive constituents.
HEMC is featured by hygroscopicity and hardly soluble in hot water, acetone, ethanol and toluene. In cold water, HEMC will swell into colloidal solution and its solubility is not influenced by PH value. Similar to methyl cellulose while being added to hydroxyethyl groups, HEMC is more resistant to saline, easily soluble in water and has higher gel temperature.

Application：
HEMC is a kind of good admixture of the powder building materials, it can be used as gelling agent and water retaining agent of cement, gypsum and lime.
HEMC is widely used in waterborne latex paint, construction and building material, printing ink, oil drilling etc to play a role of thickening, retaining water and improving constructability. It is very suitable for dry and wet mortar series products.
Package:
25kg/package. Use polyethylene film cardboard or plastic polypropylene woven bag package.
- Q: I am the person with the 1994 toyot pick up that has (had) heating problems.I found out what the problem was.The shop that I let replace the radiator, sold me/ installed a POS "cheapy" radiator.I found a significant leak / separated weld around the tops inlet.They replaced the POS radiator with a CFS radiator.It is obvious (by simply looking at it) that this radiator is a MUCH BETTER built radiator.I would still like it to run a little cooler.Does anybody know of anyone that has ever used a coolant additive? Do they really make a dofference? I am planning on running water wetter with a 25-30 to 70-75 mixture of anti-freeze to water, and then add water wetter?Does anybody know if this will make a significant difference driving across AZ and NM during the end of october?
- I run water wetter. the least amount is the best, but you need to add enough so that the water pump stays lubed. Follow the directions on the bottle and use DISTILLED WATER don't use tap water. If you use water wetter don't use any other additive..Technically water by it's self is the best if you live where it doesn't freeze. yet running only water won't get you the lubricant your water pump needs. You are using a NEW radiator cap Right? don't use the old one!
- Q: statistics question: an auto parts company advertises that its special oil additive will make the engine run smoother, cleaner, longer, with fewer repairs. an independent laboratory decides to test part of this claim. it arranges to use a taxicab company‘s fleet of cars. the cars are randomly divided into 2 groups. the companys mechanics will use the additive in one group of cars but not in the other. at the end of a year the laboratory will compare the percentage of cars in each group that required engine repairs.a) what kind of a study is this?b) will they do a one- tailed or a two-tailed test?c) if the cabs with the additive do indeed run significantly better, can the company conclude it is an effect of the additive? can they generalize this result and recommend the additive for all cars? explain
- ro a) what kind of a study is this? 2-Proportion Z-Test b) will they do a one- tailed or a two-tailed test? This is a 1-tailed test since the researchers are expecting the additive to produce a lower percentage of repairs. p2 p1 If it was a 2-tailed test, the researchers would only want to see that the percentage of repairs between the two samples are different, but not necessarily higher or lower. p2 ≠ p1 c) if the cabs with the additive do indeed run significantly better, can the company conclude it is an effect of the additive? There is always a possibility of confounding influences. For example, it does not say that this is a double-blind test where neither the taxi drivers or the researchers are unaware which cars have the additives. It will be in the researchers advantage if they can influence the results because it will benefit them financially. can they generalize this result and recommend the additive for all cars? explain Not really, since not all cars are put through the amount of driving a taxicab goes through. For example, a grandma who only drives to church on Sunday would not likely see any benefit. Hope that helps
- Q: Find a number which is 9 less than twice the additive inverse.?
- The additive inverse of x is -x (since x + -x 0). So twice the additive inverse is -2x. You need to solve the equation x -2x - 9. Adding 2x to both sides, 3x -9. Dividing both sides by 3, x -3. So -3 is the answer.
- 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?
- It is possible that water is still stuck in the transmission, torque converter, and lines. The best thing to see if there is other damage is to have a shop do a 100% tranny fluid flush. The machines they use will replace all the fluids in the tranny and converter, eliminating any water left in it. If it still doesnt drive as before, then I would suggest the tranny was ruined. Good Luck :)
- Q: I have Algebra 2 I couldn't find the answer to the question but I was just wondering could you help me? In Algebra 2 we are talking about complex numbers this was one of those problems from the homewrk that she gave us.I will be grateful if you help me.(please)Genevieve
- It's -4i. The additive inverse is the thing you add to (in this case) 4i to get the additive identity. The additive identity is 0, because you can add it all day long and not change anything. So, what do you add to 4i to get 0? Obviously, -4i.
- Q: math question
- Negatives are additive inverse of their positive counterparts (and vice versa). It refers to the fact that if you add the additive inverse (negative) of any number to itself, then you get the additive identity which is 0. The additive identity refers to the fact that adding 0 to any number will give you the original number back.
- Q: Food additives CMC various models and differences?
- Cmc is sodium carboxymethyl cellulose
- Q: Three products considering are 1. Lucas Fuel Treatment vs 2. STP Gas Treatment vs 3. Marvel Mystery OilWhich would you recommend?What other benefits will it provide?Most popular and best rated?
- I have never found a marked improvement in MPG's using any fuel additive. They tend to be either system cleaners or octane boosters. If you want better fuel economy, inflate the tires over the pressures posted on the door by two to three pounds (and more then that and tire ware increases and handling suffers). Invest in new spark plugs and air filter. Drop down to the lowest weight of oil allowed in the owners manual. Use less throttle and lift the foot on it sooner when you need to slow down, or think you will have to stop. Lighten the load in the car. If you can, locate a good set of aftermarket exhaust header/s and a low restriction catalytic. Install a air dam on the front and a modest deck extension on the back. Do not confuse a deck extension with a spoiler or wing!
- Q: The car dealer wants to charge 85.00 to clean my car injectors. Is a gasoline additive just as good?
- Using fuel with the proper amount of detergent factor is usually enough. Chevron helps. Most FI problems are due to clogging up of the AIR side of the engine, and not to the FUELside of the engine. Since you give no type of car, I am just guessing. Using the fuel treatment will only help keep the injectors clean. Fuel MIXTURE, which is controlled by the AIR side is not affected by this. Most problems are actually due to a dirty throttle body and IDLE AIR CONTROL VALVE. Cleaning these items out with Gum-out spray a few times a year will help more than the $85 treatment ever will!! Jetronic cleaner, from Germany, is the best out there.
- 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.
- This is the beer, wine and spirits area and your question has nothing to do with any of these. Try asking it in a more appropriate area and you'll stand a better chance of getting a worthwhile answer.
