Oilfield Industry Application Guide

● HEC thickening agent can be used as thickner of the well workover fluid and cementing agent. Help to provide clarification of the low fixed content solution, thus greatly reducing the structural damage to the wells. The liquid thickening by Hydroxyethyl Cellulose can be easily decomposed by acids, enzymes or oxidants, greatly improving the ability to recover hydrocarbons.
● Fluid in the well, HEC is used as proppant carrier. These liquids can be easily cracked through the process.
● HEC configuration using drilling fluid, based on its low solids content, can effectively increase drilling stability. These properties can be used to inhibit the fluid medium to high hardness of the rock and heavy shale or shale drilling.
● Reinforcement in the cement operations, HEC can reduce the hydraulic friction, minimize the loss of rock and water loss.

Q:What are the main food additives
Colorants: mainly used for carbonated drinks, fruit juice drinks, preparation of wine, pastries on the color, candy, hawthorn products, pickled vegetables, ice cream, jelly, chocolate, cream, instant coffee and other food. Often used are: amaranth, carmine, lemon yellow, sunset yellow, caramel pigments and other synthetic pigments. Some natural edible pigments such as sodium chlorophyllin are mainly extracted from plant tissues, but their pigment content and stability are generally not as good as synthetic pigments, as well as naturally equivalent pigments.
Q:Does Disneyland put food additive to make you more hungry?
come on...no they dont lol
Q:What's the additive inverse of -3.?
additive inverse is the number which when added to the given number gives sum as zero Therefore the additive inverse is 3 <-- Answer (because -3 + 3=0)
Q:Dangers of food additives?
Dangers of Food Additives and Preservatives Although additives and preservatives are essential for food storage, they can give rise to certain health problems. They can cause different allergies and conditions such as hyperactivity and Attention Deficit Disorder in the some people who are sensitive to specific chemicals. The foods containing additives can cause asthma, hay fever and certain reactions such as rashes, vomiting, headache, tight chest, hives and worsening of eczema. Some of the known dangers of food additives and preservatives are as follows: * Benzoates can trigger the allergies such as skin rashes and asthma as well as believed to be causing brain damage. * Bromates destroy the nutrients in the foods. It can give rise to nausea and diarrhea. * Butylates are responsible for high blood cholesterol levels as well as impaired liver and kidney function. * Caffeine is a colorant and flavorant that has diuretic, stimulant properties. It can cause nervousness, heart palpitations and occasionally heart defects. * Saccharin causes toxic reactions and allergic response, affecting skin, gastrointestinal tract and heart. It may also cause tumors and bladder cancer. * Red Dye 40 is suspected to cause certain birth defects and possibly cancer. * Mono and di-glycerides can cause birth defects, genetic changes and cancer. * Caramel is a famous flavoring and coloring agent that can cause vitamin B6 deficiencies. It can cause certain genetic defects and even cancer. * Sodium chloride can lead to high blood pressure, kidney failure, stroke and heart attack. To minimize the risk of developing health problems due to food additives and preservatives, you should avoid the foods containing additives and preservatives. Before purchasing the canned food, you must check its ingredients. You should buy organic foods, which are free from artificial additives. Try to eat the freshly prepared foods as much as possible rather than processed or canned foods.
Q:What is the difference between Artificial and Synthetic additives?
Artificial additive is introducing a chemical not normally found in the food, it is not innate but added to provide color, flavor, vitamins or other essential nutrient or to prolong shelf-life. Iodine is added to salt to prevent thyroid diseases, vitamin D and calcium are added to milk prevent rickets. These diseases were once very common but education, improved food storage and transport, and additives have radically reduced their incidence in many countries. Some additives are harvested from domestic plants like guar gum and are added as thickeners. A synthetic additive has been manufactured and added.
Q:Food additives can have vitamin b2 Mody
can! Vitamin B2 as a food nutrition enhancer added to the food
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:What ingredients are added to the bread
Yeast growth and reproduction of the required nutrients, collectively referred to as yeast food. Yeast growth and reproduction speed by the nutrients, temperature and pH and other environmental conditions, which is an important factor in nutrients. In the fermentation process to provide sufficient nutrition and yeast for its survival pH, can effectively improve the dough fermentation speed, increase the size of bread.
Q:What's the difference between an Additive Inverse and an Additive Identity?
additive inverse is the number you have to add to a number to make it zero if x is the number, the additive inverse is -x additive identity is the number you add to x to make it x this is always 0
Q:Chemical organic additives
Grinding aids: In the process of grinding clay, the use of a variety of grinding aids, their addition is generally a few thousandths, can play a strengthening porcelain clay smashing effect.
