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 used a gas additive once on my car when I had it filled up (STP) for fuel efficiency and added boost, is it advisable? are there any side effects of gas additives?
- As a rule of thumb, are not. One thing I've tried is a fuel system flush with BG. It can be done at a dealership, it's not a 'do-it-yourself'. I noticed a 3% increase in mileage, for the next 10k. That, however didn't justify to me the expense of the procedure. Check some of the reports and studies. Below is just one on those reports. Others can be obtained through a web search as 'gas additives for autos'. In the end, it's your call. Just get the facts, and do the math to see what it's true cost is and if there is any real savings.
- Q: Which expression is the multiplicative identity of -3(a ? b)? A.0 B. 1 C. 3(a ? b) D. -3a + 3b
- The product of a number and its multiplicative identity just returns the original number. So the multiplicative identity of any number is 1. We can justify this by saying that any number (except zero) divided by itself is 1: a/a 1 and therefore a 1*a. The additive inverse is the number that when added to the original number gives zero. In other words, it would be the negative of the original number. The additive inverse for -3(a-b) is -(-3(a-b)) 3(a-b).
- Q: How to do pesticide residues every day and food additives
- These hazards seriously affect people's health, so people not only from the ideological to recognize these issues, but also from the legal norms of the use of pesticides, involving the use of pesticides must strengthen the legal awareness, and to consciously Law enforcement, but also to strengthen the monitoring of food safety supervision and management work. The government should set up public classes, enhance the people's cognitive ability and self-protection ability, only a more in-depth understanding of the pesticide residues in food hazards and solutions, the greatest efforts to improve the relevant laws and regulations to enhance the public on the purchase of food Food and cleaning capacity, pesticide residues will be the final solution. Of course, to solve this problem is not achieved in a short time, the need for national and public unity, a common solution to pesticide residues in food, better protection of people's living standards and quality of life.
- 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. I think the owners are fibbing.
- Q: Does anyone know a site that can tell me what allergies each additive causes???
- That is near impossible. Every person is different and so is their reaction. good luck
- Q: When you buy a cup of coffee at a store or at a gas station, what do they put in the coffee besides coffee beans and water? For example, I have heard that they put preservatives in coffee sometimes. Can coffee contain any vegetable oil products (such as mono-and-diglycerides?) When I eat things with vegetable oil I am convinced I have an adverse reaction, which I think I can get to a slighter degree from drinking coffee, which is why I asked. I am convinved vegetable oil is very unhealthy.
- Pure bean coffee, can have two basic types of bean in them. The purest coffees have Arabica, but a related plant that make a bean that is similar smelling is Robusta. Arabica in its pure form is very drinkable, has a mild amount of caffeine, but Robusta was not consumed by humans until the late 1800, when coffee rust destroyed Java and other plantations. This caused a panic in the coffee industry and a search for a plant that can be used as a substitute, or for cross pollination. Robusta is now used in 30-40% of coffee blends and thee coffee manufacturer can still present it as coffee. Almost all retail coffee have this and unless marked so do 100% instant coffees. Add to that that other additives can be added to instant, and even ground coffee, the most common being chicory (which is a root vegetable), and it is possible. Stick to specialty coffees, and you may find the side effects you have disappear, since these are normally pure shade grown Arabica bean based.
- Q: The regular standard cheap honey in a jar you can buy in your local supermarket? Is that just actual honey or does it contain additives etc? Thanks.
- >There are no additives added to any honey I know of. First of all, there is so much sugar in the honey that there wouldn't be any water available to dissolve chemicals into and the only thing that is really done to honey is to pasteurize it (heat treat it). Most bugs will not grow in high solids like that due to osmotic pressure, the rest are killed by pasteurization and that means no additives are needed.
- Q: The fact that all colors on older televisions were created by combining only three different colors of light supports the _ theory of color vision.Can anyone fill this in for me please? I know it has to be either additive color mixing or trichromatic...Thanks!
- Additive color theory states that RGB are the additive primaries and a mixture of these colors creates all other colors (this is in contrast to subtractive theory which uses CMY) Although RGB color space is mapped to the visual system via xyz colors, where the full circuit would be thus: RGB>xyz>x-bar,y-bar,z-bar>Yuv>RGB Our eyes actually work on a 2 channel binary system. This means that instead of having three channels of R-G-B (a component system) we have a channel for Red vs Green and a channel for Blue vs Yellow (an opposition) system. Bottom line: Since trichromatic theory includes yellow, it has to be the additive color mixing theory which, although archaic is still heavily used
- Q: What are good fuel additives for my car?
- You'd really just be wasting your money by using it, Most fuel (modern fuel) already has all that stuff in it to keep the injectors clean etc. But for the odd time, Maybe once a year or whatever to be safe, Ask the Seller, They would be able to reccoment the best one suited to your car and year.
- Q: I‘m getting 20-some miles per gallon, but the prices at the pump really hurt.
- Well, I won't make that an absolute no. It depends on how old your car is. If you own a car that was built in the last 15 years or so, it has programmed fuel injection. A computer monitors a number of sensors located at various points in your intake system, the engine itself, and the exhaust. The computer knows when the engine is cold, and delivers the extra fuel it needs to warm up. When the engine is at operating temperature, it monitors the amount of oxygen in the exhaust gas to adjust the air/fuel ratio to its ideal proportions. This is called the stoichiometric ratio. For a gasoline engine, this is 14.7 parts of air for each part of fuel, by weight, and the computer adjusts fuel delivery to maintain this ratio. No fuel additive will have any real effect on it. The stoichiometric ratio for different types of fuels varies, but when you consider how these things are sold - in 8-oz bottles, for example, anything you'd add like this would have a negligible effect on the composition of what's in a 12 to 20 gallon tank. This being said, there are some fuel additives that can help to clean injectors that have gotten fouled with age. This will make them work better, and might save you some gas. However, if your injectors are fouled, it's probably time for a general tune-up. Finally - your gas mileage will vary with the kind of driving you do. Slow down, if you can, or take a different route to work, or leave at a different time, to avoid some of the stop and go traffic that kills gas mileage.
