Hydroxypropyl Methyl Cellulose (HPMC) is non-ionic cellulose ether, made by natural high polymer cellulose as raw material and series of chemical processing. They provide water retention and cohesiveness to mixtures. With special modification, it can be used to control thickening, water demand, workability, sag resistance, strength and other important properties of the final product.
It is widely used as thickener, adhesive, water preserving agent, film-foaming agent in building materials, industrial coatings, synthetic resin, ceramic industry, medicine, food, textile, agricultural, cosmetic and other industries.

Gypsum Adhesive
Gypsum adhesive is used to attach gypsum plasterboard and cornice to masonry wall vertically. Gypsum adhesive is also used in laying gypsum blocks or panel and filling gaps between blocks.
Because fine hemihydrate gypsum is the main raw material, gypsum adhesive forms durable and powerful joints with strong adhesion.
The primary function of HPMC gypsum adhesive is to prevent material separation and to improve adhesion and bonding. Also it helps in terms of anti-lumping.
Recommend grades: HPMC 75SS-K (60000, 100000, 150000 mpa.s)
- Q:i need what does it maens n if u can then plz do give me some examples.thank you. so muchpeace
- hehehehe you said, discharge pipe.
- Q:I usually only use them when I am traveling on long road trips, but I know they recommend using them every time you fill the tank. Is using them the same as using buying premium gas vs. the regular?
- There are only 2 that I use. Marvel Mystery Oil for top-end lubrication and Isopropyl based gas-line anti-freeze. Most of the others are just pouring money into your tank.
- Q:please explain how u got ur answer:) thx * a website attached would b great
- The additive inverse of x ia y such that: x + y = 0 0.42 + y = 0 y = -0.42 The multiplicative inverse of x is y such that xy = 1 -1.6 * y = 1 y = -1/1.6
- 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:An extended auto warranty co. says to put a product additive in my radiator? What is it? Will it mess up car?
- If it is what I think it is, that product actually is very good for your car, it is similar to the REDLINE Wetter. One of the main causes of failure in a cars engine is typically heat related, so alot of mechanics state if you can keep your engine running cooler, there is less of a chance of mechanic breakdowns. I have a few corvettes which have horrible cooling system, and corvette guys highly recommend these radiator additives to help keep them cooler. Just ask and make sure that is what it is, but being in the car business I have seen alot of extended warranty companies make you use this type of product, mainly on the 10year 100,xxx mile powertrain warranty.

- Q:For example, -(7.8)? and why?
- it would be positive 7.8 because the dash in front of the absolute value sign means absolute opposite! I just finished studying this and had a test on it yesterday (100% correct) but if the positive # is on the inside and the dash is NOT in the equation then for example | 2 | 2 but it wont have the absolute value sign on the final answer. Absolute values are easy to learn about they only have a couple rules for them, but other than that you should be fine when they come your way in the future.
- Q:5. 0?
- It's the exact opposite of the starting number so it's 4.) -12 because it's the exact opposite of positive 12.
