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: If anyone recalls my 2000 Ford Focus dying, here‘s an update. After changing the MAF sensor, fuel filter, and fuel pump, my dang Focus still had the lack of power uphill, and ocassional stall while coming to a stop (with no CEL). I‘ve used a fuel additive to clean the fuel system, and it seemed to improve greatly, only stalling once during a 2hr test drive. Now, I‘m wondering if something may be clogged of some sort. Really debating on using the SeaFoam thru‘ brake booster approach and some in the fuel tank. Any input or previous experiences???
- problematic factor. look into on to search engines like google. just that might help!
- Q: What are the commonly used additives in beer production? What is the role?
- A variety of stabilizers, itself does not react with beer, will not enter the finished product, used to improve beer non-biological stability: tannin, silica gel, PVPP, etc.
- 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: what is the additive inverse of -7+5i
- it may help preclude brake fade in automobiles and automobiles if taking position a lengthy hill, yet also reason intense driveline positioned on if no longer executed precise. Hybrid automobiles do it immediately and that i have stated myself that you in no way favor to replace brakes in a Prius if youcontinual often.
- Q: Whether the cake oil belongs to the government prohibits the use of food additives
- No, cake oil is allowed by the state, mainly used in sea cakes. Is a less toxic, relatively safe food additives. In the "National Food Additive Food Hygiene Standard (GB2760)", the use of such additives are clearly defined, the general maximum use of 6g / kg.
- Q: What is the additive inverse of a-b?
- The other answers are correct but also check to make sure you have a good rim strap or some duct tape covering the ends of the spokes. They could be causing the problem.often times old rim straps that are not replaced with a new tire/tube get broken or damaged and expose a spoke which will puncture a tube. The additional weight of a passenger would make the problem worse.
- Q: According to the provisions of the state, the use of food additives need to have what conditions
- Should not cover up the food itself or the quality of the process defects or doping, adulteration, forgery for the purpose of the use of food additives;
- Q: is it additive? i don‘t want to play for hours and hours each day, iv got course to go to, i used to go into the CBD after classes, but since there isn‘t one anymore i don‘t have anything to do.i just want to know, is it extremely additive? lol it‘s probly a stupid question but i had to ask.
- For me, yes it is. Within the first month of having it i put in at least 80 hrs of gameplay, and i have a job and girlfriend. If you liked Oblivion you probably will get addicted. The story didnt excite me the way id hoped, but it was a great game in my opinion. Just make sure you have time when you do buy it.
- Q: where is food additives banned?
- If it is banned somewhere, I would guess Cuba.
- Q: I just bought a 1975 165 hp straight 6 merccruiser in a 21‘ Manatee boat. It‘s a Chevy 6 cylinder that Merccruiser modified for boating purposes. It runs perfect but since it‘s so old do I need to use a lead additive in the gas? I can‘t ask the previous owner as it was purchased at an estate sale.
- Nope. Your Mercruiser IL 6 was designed to run on 87 octane unleaded fuel. The elimination of leaded gasoline began in 1974, GMC and Mercruiser where already producing unleaded tolerant engines in 1972. Use no additives, unless you use your boat less than once a week. If you use your boat infrequently, it's a good idea to add the appropriate amount of fuel stabilizer, such as Mercurys' Stor-Clean. If you are using ethanol enhanced gasoline (E10, E15) , it's a good idea to install a water separating filter between the tank and the fuel pump. Because ethanol can erode older types of rubber that where used in fuel lines and fuel pump diaphragms, you might also add a clear filter between the fuel pump and the carburetor. If you have any rubber erosion, you will see black stuff in the filter, and you will need to upgrade your fuel lines and fuel pump.
