Q:What is the difference between hot and cold asphalt?

Cold mixed high-strength asphalt concrete, by adding asphalt in the thermosetting resin, coupled with the right amount of solvent to form a semi-flow asphalt binder, and the appropriate mix of aggregate from the asphalt concrete mixture. This asphalt concrete is a very high strength of 60 ℃, 30mm Marshall stability of 30000N, flow 20-30 (1 / 10mm), the stability of ordinary asphalt concrete is about 3 times, with good rutting resistance. Hot asphalt is composed of different molecular weight hydrocarbons and non-metallic derivatives of dark brown complex mixture, is a high viscosity organic liquid, was liquid, the surface was black, soluble in carbon disulfide. Asphalt is a waterproof moisture and corrosion of organic cementitious materials. Asphalt can be divided into coal tar pitch, petroleum asphalt and natural asphalt three: Among them, coal tar pitch is a by-product of coking. Petroleum asphalt is the residue after distillation of crude oil. Natural asphalt is stored in the ground, and some of the formation of ore or in the crustal surface accumulation. Asphalt is mainly used for coatings, plastics, rubber and other industries and pavement and so on.

Q:Are hydrocarbons are hydrocarbons and that alcohols? Is it carbon dioxide?

Hydroxyls are directly attached to charcoal and alcohols are derivatives of hydrocarbons.

Q:Carbon compounds (except inorganic carbon compounds), hydrocarbons and derivatives of the general term is?

Organic matter

Q:Why artemisinin and its derivatives in the molecular structure of a peroxide chain, the chemical properties are more stable?

Stable, then it will not be 60 degrees that is broken down, there is no need for rectal administration ... ...

Q:Are all carbon compounds all organic?

Not ah, like CO, CO2, carbonated, carbonate is not ah

Q:Rush! Hydrocarbon and hydrocarbon derivatives system information includes chemical formula, common name, Chinese name and so on

hydrocarbon

Q:Is acrylamide an oxygen-containing derivative of hydrocarbons?

From the structural point of view, alcohol, vinegar, malic acid, citric acid and other organic matter, can be seen as hydrocarbon molecules in the hydrogen atoms are replaced by oxygen atoms and atomic groups, they are known as hydrocarbon oxygen derivatives.

Q:What is the difference between an aromatic compound and a hydrocarbon derivative?

The aromatic compound is a benzene ring containing compound, which may be a hydrocarbon or a hydrocarbon derivative. Hydrocarbons are hydrocarbon-containing compounds, and hydrocarbons containing hydrocarbons other than hydrocarbons are derivatives of hydrocarbons. The two concepts have crossed.

Q:China's largest asphalt production base where

Oil asphalt is the residue after distillation of crude oil. According to the degree of extraction of different, at room temperature into a liquid, semi-solid or solid. Oil asphalt color black and shiny, with a high temperature. Because it is in the production process has been distilled to 400 ℃ or more, and thus contain little volatile components, but there may still be high-molecular hydrocarbons without volatile, these substances are more or less harmful to human health.

Q:Sugar, fat, and so on a variety of organic matter is full of different units of the heat of the small box. (Save the heat the most efficient, the least loss of heat the most practical and most economical box).

Inorganic matter with carbon after, as if with their own ideas, began to build their own. So slowly evolved into a complex organic matter
