Iron oxides are chemical compounds composed of iron and oxygen. There are sixteen known iron oxides and oxyhydroxides, the best known of which is rust, a form of iron(III) oxide.
Iron Oxide Powder and oxyhydroxides are widespread in nature and play an important role in many geological and biological processes. They are used as iron ores, pigments, catalysts, and in thermite, and occur in hemoglobin. Iron oxides are inexpensive and durable Pigment And Dye, coatings and colored concretes. Colors commonly available are in the "earthy" end of the yellow/orange/red/brown/black range. When used as a food coloring, it has E number E172.
Iron Oxide Pigments materials yield pigments that are nontoxic, nonbleeding, Ethylene-Vinyl Acetate weather resistant, and lightfast. Natural iron oxides include a combination of one or more ferrous or ferric oxides, and impurities, such as manganese, clay, or organics. Synthetic Red Iron Oxide can be produced in various ways,Melamine Powder including thermal decomposition of iron salts, such as ferrous sulfate, to produce reds; precipitation to produce yellows, reds, browns, and blacks ; and reduction of organic compounds by iron (e.g., nitrobenzene reduced to aniline in the presence of particular chemicals) to produce yellows and blacks. Reds can be produced by calcining either yellow or blacks.

The second advantage is to avoid the patient's skin subcutaneous insulin injection pain. Insulin pumps are connected to the skin by a continuous infusion hose, to avoid having to inject insulin before each meal.
The third advantage is that due to precise control of the amount of insulin injected, liquid medication is saved. In the past, high blood sugar will hit a needle, but if all of a sudden overdose will lead to hypoglycemia, hit less and not enough, and now the use of insulin pump continuous input, you can precisely control the dose, the number of hours per hour can be controlled, Generally speaking, injection can save more liquid than injection.
The shortcomings of insulin pump The first is that although it can carry, but in some sports, such as swimming, or intense physical activity, it is not convenient;
The second is the injection site due to prolonged needle buried in the skin, there will be inflamed inflamed;
The third possibility is that there is a problem with the microcomputer program, the motor stops working, or the hose is blocked. At this time, the liquid medicine can not be input, and the patient may be insulin-deficient without knowing it, causing some complications.
Insulin pump advantages and disadvantages
The first is that you can precisely control the dose of insulin injected. If the insulin is administered subcutaneously, the overdosage will result in hypoglycemia, whereas the underdosage will cause an overdose of blood glucose, which can now be finely controlled. Control the amount of blood sugar in the body.
