Alkyd paint is also known as alkyd resin paint or alkyd resin coating. It is mainly composed of alkyd resin and is currently the largest type of paint produced in China.
The paint film of alkyd paint is flexible, resistant to friction, and has good adhesion; after the paint film dries, it forms a high-degree network structure, which is not easy to age, has good weather resistance and long-lasting gloss; .Resistance to mineral oil and alcohol solvents Good. After baking, the water resistance, oil resistance and insulation of the paint film can be greatly improved; the construction is convenient, and it can be brushed, sprayed, dipped, etc.
Carbon tetrachloride is a colorless toxic liquid, can dissolve fat, paint and other substances, volatile liquid, with a slightly sweet smell of chloroform. The molecular weight is 153.84, the density is 1.595g/cm³(20℃) at room temperature and pressure, the boiling point is 76.8℃, the vapor pressure is 15.26kPa(25℃), and the vapor density is 5.3g/L. Carbon tetrachloride is insoluble with water, but miscible with ethanol, ether, chloroform and petroleum ether. It is non-flammable and was used as an extinguishing agent, but was discontinued because it reacts with water at temperatures above 500 degrees Celsius, producing carbon dioxide and toxic phosgene, chlorine and hydrogen chloride gases, and because it accelerates the breakdown of the ozone layer. The use of carbon tetrachloride is stric......

Can be used as antibiotics, spices, oils, resins, rubber solvents and extractants. Mixed with carbon tetrachloride can be made into non-freezing fireproof liquid. It is also used in the emission of smoke agent, fumigant of grain and standard liquid for calibrating temperature. Industrial products are usually added with a small amount of ethanol so that the resulting phosgene reacts with ethanol to produce a non-toxic diethyl carbonate. Before using industrial products, a small amount of concentrated sulfuric acid can be added, shaken, washed, dried by calcium chloride or potassium carbonate, and chloroform without ethanol can be obtained

Nitrogen trifluoride in the microelectronics industry as a kind of excellent plasma etching gas, cracking for active fluorine ions in ion etching, the fluorine ion of tungsten and silicon compounds, high purity nitrogen trifluoride excellent etching rate and selectivity to silicon and silicon oxide, it at the time of etching, the etched surfaces without leaving any residue, is a very good cleaning agent, At the same time, it has been widely used in chip manufacturing and high energy lasers.

The largest amount of solvent oil for coating (commonly known as paint solvent oil), followed by edible oil, printing ink, leather, pesticides, pesticides, rubber, cosmetics, spices, medicine, electronic components and other solvent oil. Currently there are about 400-500 solvents on the market, of which solvent oils (hydrocarbon solvents, benzene compounds) account for about half.
