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 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: and the multiplicative inverse of 1/4? thank you for your help: The inverse with respect to an operation of a certain number is a number which after operating with it equals to identity. Identity with respect to an operation is a number which after operating with the particular number a equals to a. e.g. Identity with respect to addition (additive identity) is 0 because a + 0 a Whenever we add 0 to anything the answer will always be the original number with which it was getting added. and Identity with respect to multiplication (multiplicative identity) is 1 because a x 1 a Whenever we multiply anything by 1, the answer will always be the original number with which it was getting multiplied. So inverse with respect to addition (additive inverse) of a number would be such a number that when we add both the numbers, the sum should be equal to identity (additive identity 0) a + (-a) 0 so, additive inverse of a number is negative of that number. That means additive inverse of 2 is -2, of 5 is -5, of 6^5 is -6^5 and so on. Similarly the inverse with respect to multiplication (multiplicative inverse) of a number is such a number that when we multiply both of them, the product should be equal to identity (multiplicative identity 1) a x 1/a 1 so, multiplicative inverse of a number is reciprocal of that number. That means multiplicative inverse of 2 is 1/2, of 5 is 1/5, of 6^5 is 1/6^5 and so on. So, ADDITIVE INVERSE OF 2/3 is -2/3 and MULTIPLICATIVE INVERSE of 1/4 is 4

Q: I just bought a 2001 Dodge Ram 3500 and the former owners told me I needed to add fuel additive to it. I was wondering if I actually do or if it is just for a cosmetic reason: You don't have to but a lot of people do. Its a lot better for your truck if you do. My buddy has a 99 3500 and he puts it in every other time he fills up.

Q: I have a main oil seal leak on my 98 Dodge Caravan. I would have it repaired, just have a new engine put in, or buy a new car, but I don‘t have the money right now for any of those options. I have never liked the idea of using additives but if it could put off the inevitable a while longer, do I have anything to lose? I have two people in my life telling me two different things. My dad doesn‘t believe in using additives and says they cause more harm than good. The other person says some additives are actually good and don‘t harm anything. They said Lucas was a very good one, as well as a couple others. What‘s your take?: Using some additives that say they will swell-up seals will do that. But, that makes them less resistant to stresses, and may fail faster than without using the additive.

Q: What is an indirect food additive?: Indirect Food Additive - In general, these are food additives that come into contact with food as part of packaging, holding, or processing, but are not intended to be added directly to, become a component, or have a technical effect in or on the food. Indirect food additives mentioned in Title 21 of the U.S. Code of Federal Regulations (21CFR) used in food-contact articles, include adhesives and components of coatings (Part 175), paper and paperboard components (Part 176), polymers (Part 177), and adjuvants and production aids (Part 178). Currently, additional indirect food additives are authorized through the food contact notification program. In addition, indirect food additives may be authorized through 21 CFR 170.39.

Q: what are the food additives commonly for use?: Hey i'm here for the first time. I found this question and I find the answers truly valuable. I'm hoping to give something back and help others too.

Q: I have two jars of horseradish (or similar); one is natural and the other has added color / preservatives. how will this affect the taste? This answer seems rather straightforward, but I have been looking online for an article or some kind of proof. Thanks in advance.: Additives always affect the taste.

Q: What additives can be used in concrete during hot weather.?What additives can be used in concrete duringcold weather?: cold-- readymix has hot water and a % of chloride 1 or 2 % At the time of pour the temp should be around 64 degrees summer-- I never use additves.Just a sack mix with sometimes I have a % of air added to the mix.

Q: Safe to consume chemicals that counteract additives in food?: There are about a million food additives, including unintentional additives, so specific chemicals would be needed to counteract each of these many additives, most of which would be of doubtful safety. Example: Salt substitute potassium chloride, can help our body deal with excess salt, but too much potassium chloride is also bad. Neil

Q: I know that Q itself is not cyclic, but what about proper subgroups of Q. All subgroups I can think of so far seem to be cyclic and therefore generated by one fraction. For example if the cyclic group generated by m/n is represented as &lt;m/n&gt;, then every subgroup of this form would be contained in &lt;1/mn&gt;.For example, &lt;2/3&gt; is contained in &lt;1/6&gt; etc.: How about a short direct proof: We can write the generators with a least common denominator D: {Ni/D} for i=1..k Letting F=GCF{Ni}, each Ni/D is a multiple of F/D. So every generator of the subgroup, hence the entire subgroup, is in the cyclic group <F/D>. By Euclid's algorithm, there exist integers Ai so that ΣAiNi=F. ? F/D=ΣAi(Ni/D) Hence F/D, and so all of the cyclic group <F/D>, is in the finitely generated subgroup. Therefore <F/D> is the subgroup in question.
