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.

Masonry Mortar
Masonry mortar is composed of binders like cement or lime and some other aggregates. It is used for brick or block laying.
Masonry mortar is becoming increasingly popular for its easy handling. After hardening, good adhesive and compressive strength are required for this application. It enhances pot life and provides water retention as well as good workability. Additionally, it prevents bleeding or material-separation and crack formation.

- Q:Find the additive invers of -9 on the 12-hour clock?
- Well!!!!!! In a 12 hour clock, 12 is equivalent to zero Now, If you have any number A and if its additive inverse is B, then, A + B 0 Here, - 9 + B 0 Here 0 may be 12 also!! - 9 + B 0 or 12 Thus, B 9 or -3
- Q:The main components of commonly used antioxidants in food additives, as well as the principles of antioxidant?
- Deoxidants are also known as free oxygen absorbers, free oxygen scavengers or deoxidizers, etc. It is a substance capable of absorbing oxygen. In the food sealed packaging, while adding the packaging can remove the oxide material, remove the packaging container free oxygen and dissolved oxygen, to prevent food due to oxidation and mold, deterioration and so on. Deoxidizer for food not only can effectively inhibit the deterioration of the quality of the contents, but also to maintain the original food color, smell, taste, pest control, bacterial growth, maintenance of nutrients, extend the preservation time, so the use of deoxidizer preservation Food is a high quality, effective, convenient and safe method of packaging preservation. Deoxidizer is the most commonly used iron series deoxidizer and sulfite deoxidizer. Deoxidation of deoxidizer is based on chemical reactions, so its oxygen removal capacity with the reaction series, time, temperature and other conditions vary. When the quick-acting deoxidizer is present in the sealed packaging container, the free oxygen can be reduced to less than 1% in about one hour and eventually to 0.2%. Slow deoxidation agent takes 12-24 hours, but the final deaeration capacity is the same, free oxygen can be reduced to 0.2% or less. Deoxidizer as a new material for food preservation, has its unique advantages. It is filled with food in the same container, the deoxidizer absorbs oxygen in the container, so that the container was anaerobic state, food can be preserved.

- Antimicrobial agents, which prevent spoilage of food by mold or micro-organisms. These include not only vinegar and salt, but also compounds such as calcium propionate and sorbic acid, which are used in products such as baked goods, salad dressings, cheeses, margarines, and pickled foods. Antioxidants, which prevent rancidity in foods containing fats and damage to foods caused by oxygen. Examples of antioxidants include vitamin C, vitamin E, BHA, BHT (butylated hydroxytolene), and propyl gallate. Artificial colors, which are intended to make food more appealing and to provide certain foods with a color that humans associate with a particular flavor (e.g., red for cherry, green for lime). Artificial flavors and flavor enhancers, the largest class of additives, function to make food taste better, or to give them a specific taste. Examples are salt, sugar, and vanilla, which are used to complement the flavor of certain foods. Synthetic flavoring agents, such as benzaldehyde for cherry or almond flavor, may be used to simulate natural flavors. Flavor enhancers, such as monosodium glutamate (MSG) intensify the flavor of other compounds in a food. Bleaching agents, such as peroxides, are used to whiten foods such as wheat flour and cheese. Chelating agents, which are used to prevent discoloration, flavor changes, and rancidity that might occur during the processing of foods. Examples are citric acid, malic acid, and tartaric acid. Nutrient additives, including vitamins and minerals, are added to foods during enrichment or fortification. For example, milk is fortified with vitamin D, and rice is enriched with thiamin, riboflavin, and niacin. Thickening and stabilizing agents, which function to alter the texture of a food. Examples include the emulsifier lecithin, which, keeps oil and vinegar blended in salad dressings, and carrageen, which is used as a thickener in ice creams and low-calorie jellies.
- 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 hear all this stuff about it coming from the same place but the fancier gas places add additives, yes the all come from the same pipe line (History Channel - Modern Marvel). They all the same additive. It is all marketing. good Luck. P.S. I've been buying the cheapest gas since 1985. Never had problems because of dirty fuel.
- Q:of 0.645 M KCl and 600 mL of 0.355 M MgCl_2? please help!!! cant seem to figure this out. Thnaks
- First, we assume that both KCl and MgCl2 are fully dissolved in the solution (both are highly soluble in water which make it a very valid assumption. Second, we determine the number of moles of Cl- we can obtain from each solution: 0.235 L (0.645 mol/L) 0.152 mol 0.600 L (0.355 mol/L) 0.213 mol Total number of Cl- 0.365 mol Third, because the volumes are additive, the total volume would be 0.835 L. Now, we have all the pieces. Concentration will be 0.365 mol/0.835 L 0.437 M of [Cl-]
- Q:a whole lot of VST‘s advertise either being Additive or Subtractive synths, and I cant tell the difference.
- C'mon. You really don't know this? A keyboard is an instrument withA KEYBOARD. It could be a grand piano, a cheap little electronic thing, a big expensive keyboard that rock stars use on stage, it could be asynthesizer. If it has a keyboard, it'sA KEYBOARD. There are lots of keyboard instruments around that have thousands of different sounds and instruments on them with sequencers and percussion, etc. People call these keyboards. But they're also synthesizers because they synthesize their sounds. Is there a piano inside that little keyboard? No. It's a synthesized piano sound. A synthesizer is an electronic instrument that synthesizes sounds. The vast majority of synthesizers are keyboard instruments. There are guitar synthesizers, there are drum synthesizers, there are all sorts of synthesizers. But most synthesizers are keyboard instruments. So if someone says I play synthesizer, it probably means he/she plays a keyboard synthesizer. If someone says I play keyboard, it could mean piano, organ, synthesizer, etcany instrument with a keyboard. But these days, it probably means they play a keyboard synthesizer. There's also analog versus digital synthesis, but that's for another day. Just because you know how to play the sounds on your synthesizer doesn't mean you're a keyboard player. A keyboard player knows how to play real keyboard instruments like pianos and organs. So if your keyboard playing consists of triggering sounds on your synthesizer, you really can't claim to be a keyboard player.
- Q:Any way better than let‘s say Marlboro?
- Plain old tobacco smoke with nothing added contains over 2000 different toxins. There is no healthy way to smoke, sorry. And don't think I'm judging because of my profession. The more smokers the more job security for me!
- Q:What is the additive?
- Look at the ingredients ingredients table you know. Not much to say.
- Q:Im looking for the oil additive they call free?
- Oil additives are junk and can actually ruin your engine. If they were so great, then the racing teams would use them. I have a degree in chemistry, and can tell you that Slick 50 (teflon) and all the rest are a waste of money. Keep your oil changed on a regular basis (3000-5000 miles depending on your driving) and your motor will run smoothly for a long time.
