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.

- Q:what is the additive inverse of 12? please justify your answer?
- In general we have that y is the additive inverse of x if the following holds: x + y 0 Therefore, let x 12 and lets solve for y: 12 + y 0 y -12 Hope this helps!
- Q:What kind of additives are not brittle crisp, crisp, and delicious
- Note the temperature of the oil
- Q:What type of milk contains more hormonal additives, 2% or whole?
- well actually i think u should just go with a brand that says there is no added hormonal additives.You can basically find these in organic milk,but they are a bit costlier. I wish they didnt add hormones in milk in the first place.
- Q:Also, what water parameters (ph, nitrates) are necessary
- its not true. the reason is because alot of the car and engine would have to be redesigned to allow it to slide out, such as moving the radiator and most of the other components out of the way. it would also require the car to have a transmission that also slides out (which cant happen because its eventually connected to the wheels). plus it would be a MASSIVE danger if someone got into a wreck. in most cars the engine is bolted on the frame well enough so it wont fly off if it was slammed into (if the engine can slide one way it can slide the other.) PLUS the engine is the HEAVIEST part of the car. easily peaking at over 800lbs. the heaviest duty sliders you can find work upto 400lbs any higher and they fail
- Q:Just speaking of regular unleaded fuel. Is paying the higher price of (ex. Exxon) gas practical, or is the cheaper stuff (ex. Valero) just as good. I hear all this stuff about it coming from the same place but the fancier gas places add additives, but is that just a gimic to make it seem better so you‘ll pay more?
- I gotta be honest with you, when I go to Exxon, the car can go 3 more days without a fill up from Exxon then it would from any other station. I drive a Nissan Altima Hybrid. With Exxon I fill up every 17 days, elsewhere, it is like 14 days.To me, it's not hype.
- Q:about a fuel additive?
- if you cant buy it at a store you best wait til it shows up id pass
- Q:how to find the additive inverse of *square root* 3 then add 5?
- the additive inverse is just the negative. so the additive inverse of sqrt3 + 5 is - sqrt3 - 5
- Q:which is worse additives in food or in drinks?
- it never hurt my engine any.
- Q:Its hard to find lunch meat without any preservatives in it. And the ones that i do find are expensive.I was thinking that if i bought lunch meat from a deli in the form of a solid, cold-cut, piece of meat, then there wouldn‘t be any additives in it. Is this true???
- No, it's not. Most deli meats contain some sort of additives.
- Q:I have heard I do and I have heard I don‘t. If so by running a tank of gas through it without additive would that of hurt anything?
- High performance cars from the 60's and early 70's require high performance gasoline. Unless the engine has already been modified, pre-1971 cars require leaded high octane gasoline to run correctly. Because leaded gasoline is no longer sold in the United States, owners of these types of vehicles need to buy lead substitute additives (around $2-$5 per bottle). A bottle is generally good for one tank of gas. Lead is critical because it acts as a lubricant for the internal engine parts and stops them from wearing out prematurely. Engines built in 1971 and later are built to run on unleaded gas so adding lead substitute is not needed. In fact, lead damages Catalytic Converters, which are required on cars built after 1977, and is more harmful to the environment. Adding a lead additive to a pre-1971 engine will literally prevent the engine from beating itself to death
