Magnesium oxide trait

White amorphous powder. Odorless, tasteless, non-toxic. Due to different preparation methods, there are light weight and heavy quality. Strong refraction in the visible and near-ultraviolet range. It is easy to absorb water and carbon dioxide in the exposed air and gradually becomes basic magnesium carbonate. It is lighter and heavier and heavier. It combines with water to form magnesium hydroxide. It has a slightly alkaline reaction and the pH of the saturated aqueous solution is 10.3. However, it is very soluble in dilute acid, very slightly soluble in pure water, and its solubility is increased by the presence of carbon dioxide. It is a mild catalyst. Do not dissolve in ethanol. The relative density (d254) was 3.58. Melting point 2852 ° C. The boiling point is 3600 °C.

Magnesium Oxide(MGO)-optical Coating Material

The main purpose:

A: The coating used on the surface of the lens:

1. It has strong anti-reflection, and the permeability to light will increase. The wearer will feel less glare and the object will be more real and bright.

2. It will not reflect light, and it is not suitable for grinding, so clean

3. And can effectively prevent ultraviolet or computer radiation (because the lens has two kinds of film, one is anti-ultraviolet film, one is anti-computer radiation film)

4. How to confirm whether there is coating, aligning with the light source, if there is purple or green reflection, it means anti-reflective protective film,

Two: coating on the glass surface

1. Let the surface of the object be in a new state for a long time.

2. The surface of the object will not be easily contaminated or affected by external materials.

3. It is easy to clean up some dirt on the surface of the object when cleaning the surface of the object.

Three: coating used on the surface of the car

1. Automotive coating has the function of preventing oxidation and aging of paint surface

2. It can greatly improve the clarity of the paint surface varnish, making the paint look more dazzling.

3. Corrosion resistance

4. High temperature resistance

5. Anti-scratch

6. Easy to clean

7. Ultra-lasting and powerful toughness and extensibility

8. Ultra-environmental use of water-based environmentally friendly materials, self-oxidation

9. Super water repellency

Four: other uses

1. Determination of sulfur and pyrite in coal and sulfur and arsenic in steel. Used as a standard for white pigments.

2. Used as an acid and antiulcer drug, an antacid, and a laxative. The acid resistance is stronger, slower and longer lasting than sodium bicarbonate, and does not produce carbon dioxide. It reacts with gastric acid to form magnesium chloride, which releases magnesium ions and stimulates intestinal peristalsis, which has a laxative effect. It is suitable for patients with hyperacidity, stomach and duodenal ulcer with constipation. For those without constipation, the laxative effect can be corrected with calcium carbonate.

Safety measures

1. Store in a cool, ventilated place. Do not touch the product directly with your hands. Wear gloves when handling.

2. Skin contact: Remove contaminated clothing and rinse immediately with water for at least 15 minutes.

3. Eye contact: Immediately lift eyelids, rinse with running water for 10 minutes or rinse with 2% sodium bicarbonate solution

4. Inhalation: Quickly leave the site to fresh air. Keep the airway open. Give oxygen when breathing is difficult. Take artificial respiration immediately when breathing stops and seek medical attention.

5. Ingestion: The person who is inadvertently lavage immediately. Seek medical attention.
