Application

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:Can food additives be eaten directly? why?
Food additives and food different, they have not experienced in practice long-term test, it is difficult to determine its safety. After the Second World War Japan officially began to use food additives in food, so far only a few decades time. Therefore, its security is still unable to determine, only to wait until a few years later it is possible to fully understand whether they are harmful to the human body.
Q:Differences between extreme pressure additives and lubricating additives
Adding one or more compounds in the lubricant to give the lubricant a certain characteristic or to improve some of the properties already present in the lubricant. The role of additives is to improve the performance of base oils and to add new properties. Existing properties include: viscosity, viscosity index, pour point and oxidation resistance. New features include: cleaning and suspension capacity, abrasion resistance and corrosion inhibition
Q:Whats additive toxicity?
Chundering Definition
Q:The disadvantages of food additives
Carcinogenic problems. Such as some artificial sweeteners, pigments and other animal experiments confirmed by carcinogenic effects. Such as creamy yellow pigment can induce rat liver cancer, sweetener Ganjing and phenylurea can also cause animal tumors. In recent years also found that the coloring agent sodium nitrite and meat, fish and other foods in the amine react to form a strong carcinogenic nitroso compounds.
Q:Does MSG belong to food additives?
In accordance with the provisions of Article 11 of the General Administration of Quality Supervision, Inspection and Quarantine of Foodstuffs, the use of sweeteners, preservatives, colorants and other food additives directly in food shall establish food additives in the list of ingredients, The names of the various food additives used under this item are also marked.
Q:What is the hot pot additive?
Fragrance, pepper fine, hot pot red than "a drop of incense" more fierce, cheap hot pot has become a "chemical pot"
Q:Pros and cons of food additives?
Pros: Grown without pesticides, synthetic chemicals, preservatives, non-irradiated, non-genetically modified, better nutrition for the person ingesting them, less toxicity for the person ingesting them, feeling of better well being is markedly noticeable Cons: Expensive, shorter shelf life ,limited availability, limited selection If you hear news reports telling you that there is no difference between the two, consider the source : It's just like most western medicine doctors telling people that vitamin supplements don't help people. Of course they are going to say that. Doctors want you to be sick so you'll buy their pimp's (pharmaceutical companies) drugs and spend money on doctor visits. Also pharmaceutical companies and most western medicine doctors don't make any money off of vitamin supplements or the fact that you are healthy.. Something to think about, huh? Believe it... cause it's true. It's a sad state of affairs, but it's definitely true
Q:The food additive is trisodium phosphate or sodium dihydrogen phosphate
Trisodium phosphate and sodium dihydrogen phosphate in the food additive GB2760 have, sodium dihydrogen phosphate function: water retention agent, used in infant formula and weaning food; trisodium phosphate function: moisture retention agent, stabilizer, acidity adjustment Agent, used in dairy products, oil products, prefabricated meat products, cooked meat products and beverages.
Q:What roles do food additives play in the colour and flavour of food and in the preservation of some food items?
Citric acid is a common and natural additive that is used to retain color of foods (like putting lemon juice on apples to prevent them from browning), it also adds a bitterness that can enhance the flavors of some foods. They will also do a cure for corned beef using potassium nitrate for the bright red color because otherwise, when it's cooked in liquid, it can turn a most unpleasant gray color that wouldn't be attractive to look at. It's about marketing, you eat with your eyes first so if a product doesn't appeal to you visually you probably wouldn't buy it to eat.
Q:Additive and Multiplication Inverse questions help?
1. Additive inverse: To find the additive inverse find what the number added to will equal zero. So basically, set up an equation to finda." z+a=0 -2+4i+a=0 a=2-4i And so the additive inverse of -2+4i is 2-4i. (notice that it was simply the originally number multiplied by -1). 2. Multiplicative inverse: Basically the same thing only the two numbers are multiplied. z*m=1 (1-i)*m=1 m=1/(1-i) So that's the answer. I suppose you should probably simplify it though. 1/(1-i) * (1+i)/(1+i) [multiply by the conjugate of the denominator to get the complex number out of the denominator). (1+i)/(1-i²) (1+i)/(1--1) (1+i)/2 So that's you're answer.
