Product introduction

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 Filler/Joint Filler

Gypsum filler or Joint filler is a dry mixed mortar that is used to fill the joints between wall boards.

Gypsum filler consists of hemihydrate gypsum as a binder, some fillers and additives.

In this application, HPMC provides strong tape adhesion power, easy workability, and high water retention etc.

Q:whats additive inverse?
The additive inverse of a number is the number that will add to it to make zero. For example, the additive inverse of 7 is -7 because: 7 + (-7) = 0 Basically, it's the number with the opposite sign. Incidentally, zero is the only number that is its own additive inverse. -2 and 2 -81 and 81 15 and -15 -3.5 and 3.5 0 and 0
Q:I recently buy a 1992 Honda Civic from one German Lady. The car is in excellent condition. Yesterday added some additive in fuel tank as it says on the bottle (cleans fuel system). Today at morning could not start the car. Are these additive have any effect on car or that is just waste of money?
if that addative is floating on top of your fuel then its most likely going into the fuel intake and then the engine before or without the fuel hope this helps
Q:After doing some research I found that gasoline quality is very poor right now. And I am looking for a fuel additive that will help keep emissions down as well as increase MPG; however, I want to know if these products will void my warranty.
Never heard of additives voiding a warranty. Really couldn't prove if you were using an additive anyways.
Q:I got a car but the guy who owned it b4 me didnt really seem to take care of it any good. I‘ve never really used fuel or oil additives but im goign to try and do all i can to keep it running nicely for now. and by fuel additives i do not mean the octane boost, i mean the fuel system cleaner and fuel savor.
The additives put in your fuel tank rarely work. They typically fall and sit on the bottom of the tank. One fuel system cleaner that I know works is SeaFoam. You will have to suck this SLOWLY into the intake manifold. DO THIS OUTSIDE IN A WELL VENTILATED AREA! It produces a lot of smoke. My car was blowing giant smoke rings. You can also use the rest of it in the fuel tank. Seafoam mixes well because it isnt as thick. Hope this helps
Q:Is it really true that Additives & stimulants help for quality growing? ?
It depends what they are, and whether your plants are growing near to their optimum level. Overall, if your plants are getting high quiality nutrition and good levels of lighting, then you'll get good quality productive plants. There are 'miracle' cures out there, but much of it is hype and, in my opinion, prays on the grower who is not a horticultural scientist. Overall, if you can apply organic grade additives then you'll not affect the ability of your plants to be nutritious and fulfilling etc. This also depends on how you're growing, as soil based growth is likely to provide most nutrients that plants want, hydroponically grown produce should have its input tailored to what you're growing, as well as its position in the growth cycle. I recommend researching the individual plant types that you're growing - some have greater difficulty with the uptake and utilisation of certain nutrients, but these are the rarity, and not the norm. Plants naturally contain hormones etc, and can usually produce them in sufficient quantity to manage their growth, flowering and seed production. If you've got products in mind, compare similar products as it's easy to pay too much for roughly the same stuff. That's if you really need it, of course. Edit your question if you've got any specifics, otherwise feel free to message me for any other advice. Hope this helps. Good luck! Rob
Q:Why don‘t smokers stand up to tobacco companies? Smoking would be a lot less harmful if it weren‘t for all the additives. I would venture out to say that a lot of smokers, indeed, enjoy smoking. they would probably continue to smoke out of their own will, with the absence of added addicting substances. Also, why do cigarette companies add lethal chems to their tobacco? What is the purpose? Would it be possible to form a smoker‘s strike? The government/FDA is not going to step in because they are in bed with the cigarette companies. Thoughts?
Sackings is right on the money.
Q:explain how the additive color model and the subtractive color model in commercial printing are related and why the standard painter subtractive primaries are not used. THANKS!
Primary colors are :Blue, Red, Yellow. I don't know why someone would say green, because the point is that mixing two of the 3 colors make another, for example blue and yellow makes green.
Q:What does it mean when you have a dilution problem whos volumes are additive? For instance, What is the concentration (Molarity) of the solution made by diluting 25.0 mL of 3.00 M HCl with 75.0 mL of water? (Assuming that volumes are additive.)I know that this is an M1V1 M2V2 problem, but does this mean that the volumes must be added, or that they have already been added and I can proceed with the problem?
The phrase assume volumes are additive means that the problem wants you to assume that when you add 75ml water to 25ml 3M HCl you end up with 100ml of solution. This may seem silly, but in reality, you will probably end up with some volume less than 100 (albeit a very small amount less) since the HCl in solution affects the density and will result in a slightly different volume. The qualifying phrase simplifies the math for the problem. If you use your equation M1V1 M2V2, M1 3, V1 25. V2 100, and solve for M2.
Q:Black Female artist of 2003 or 2004
I've never seen one of these pamphlets because I live in a civilized part of the country. If I saw anyone ever put one of those things on my car, I'd beat the living turd out of them. Then I'd run my car over their head.
