Product introduction

Polyanionic Cellulose referred to as PAC, is made from natural cellulose by chemical modification and the obtained water-soluble cellulose ether derivatives, is an important water-soluble cellulose ether, its sodium salt is usually applied. Polyanionic Cellulose has good heat stability and salt tolerance, anti-bacterial and strong. The product is prepared with a good drop of fluid mud water loss, inhibition, higher temperature resistance. Widely used in oil drilling, especially offshore oil drilling wells and salt water.

Q:What's the additive inverse of -3.?
the answer is 3. the additive inverse of a number is the number you add to make the sum equal zero.
Q:Food additives in the fixed from the deformation
Depends on what you do food and solid state is jelly or Liangpi, or soy products or dishes? The effect of the food additives are gelatin, pectin, carrageenan, Liangpi Wang, within the fat, thickeners, stereotypes agents, stabilizers, etc. hope to adopt, thank you
Q:The percentage of food additive usage is relative to what
Generally expressed in mg / kg. Ie how many additives are added to 1 kg of food
Q:Ordinary flour and what food additives can be made into gluten
In order to increase the flour gluten, you can use flour treatment agent, flour reinforcement, azo formamide, is not recommended flour plus gelatin, is illegal. The In fact, more additives, in fact, not as ordinary flour into high-gluten flour, out of gluten is.
Q:Additive inverse and mutiplicative inversre?
Additive inverse of 0.4 is -0.4, multiplicative inverse is 1/0.4 = 1.5. Additive inverse of -1.6 is 1.6, multiplicative inverse is 1/1.6 = 0.625 Additive inverse of 5 5/6 is -5 5/6, multiplicative inverse is 1/(5 5/6) = 1 /(35/6) = 6/35. (Do you see the pattern?) I hope that helps!
Q:What are the best oil and transmission additives?
I have also used products by Lucas with good results. If you have any sort of warranty on an engine or transmission, make sure that the use of additives doesn't void the warranty.
Q:Candy additives
Candy can be used in more types of additives, such as pigment, acidity agent, stabilizer, coagulant, moisture retention agent, thickener, sweetener, emulsifier, etc., according to the needs and national regulations to choose to use.
Q:Additive color mixing, or trichromatic?
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:Provisions on the supervision and administration of the production of food additives
What kind of additives do you mean, there are many kinds of additives, different additives have different provisions.
Q:B-carotene is a food additive?
Is a food additive. Β-carotene, but also orange fat-soluble compounds, it is the most common in nature and the most stable natural pigment. It is present in plants in plenty, so that fruits and vegetables have full yellow and orange. Beta-carotene is also used as a colorant for food (eg margarine). At present in China to allow the use of synthetic pigments are amaranth, carmine, red red (cherry red), new red, temptation red, lemon yellow, sunset yellow, bright blue, indigo and their respective aluminum lake. As well as synthetic beta-carotene, sodium chlorophyll and titanium dioxide.
