What does inorganic material mean

Question 1: What does it mean to say in chemistry that organic and inorganic materials will produce carbon after combustion, but do not produce carbon, carbon monoxide can be burned, inorganic or not much help,

Instead, it is inorganic

This method is also applicable to those exceptions to the carbon-containing organic materials, simply look at the above definitions, which usually refers to compounds that do not contain carbon

But inorganic Inorganic is short for "fire to identify organic"

In reality, to differentiate between organic and inorganic materials, it is important to understand the meaning of organic materials.

But inorganic Inorganic is short for inorganic compounds, that is, "fire to identify organic"

In general, but can not be burned, for the distinction between the reality of organic matter, such as carbon dioxide, although containing carbon, so this method can be identified as inorganic .

Question 2: Inorganic classification of inorganic materials Inorganic materials can generally be divided into two categories: traditional and new inorganic materials. Traditional inorganic materials are materials prepared with silica and its silicate compounds as the main components, so they are also called silicate materials. New inorganic materials are materials made from oxides, nitrides, carbides, borides, sulfides, silicides, and a variety of non-metallic compounds by special advanced processes.

Question 3: What are organic and inorganic materials? Organic is a material with life functions, inorganic is a material without life functions

Question 4: What are inorganic materials? Inorganic materials are harmful to human health? Inorganic materials can generally be divided into two categories: traditional and new inorganic materials. Traditional inorganic materials refers to silica and its silicate compounds as the main component of the preparation of materials, so also known as silicate materials. New inorganic materials are made of oxides, nitrides, carbides, borides, sulfides, silicides, and a variety of non-metallic compounds by special advanced technology.

Construction materials are used in construction projects in a variety of materials and their products,

It is the material

foundation of all construction projects, whether it is the construction of residential housing, office buildings, or stores, hotels need a lot of construction materials. Construction materials

A wide variety of metal materials such as steel, aluminum, copper; non-metallic materials such as gravel, masonry, ceramic products, lime,

cement, concrete products, glass, mineral wool; plant materials such as wood, bamboo; synthetic polymer materials, such as plastics, coatings

materials, glues and so on. There are also many composite materials.

Decorative materials are materials used for building surfaces

(

walls, columns, floors and ceilings

)

The decorative effect of the material, also known as decorative

surface materials. Generally it is in the main construction

(

structural engineering and pipeline installation

)

completed, in the final stage of decoration

materials used.

Interior decoration in ancient and modern China and abroad has long been,

Especially after the reform and opening up,

With the improvement of people's living standards

High, people are no longer just satisfied with housing, but require a comfortable, beautiful, elegant living environment. So indoor

decoration

, decoration gradually hot up, the grade of the decoration is also increasing. There are many materials used for decoration, such as floor tiles,

floor leather, carpets, wall low, cinnamon carpet and so on. With the development of the construction industry and the improvement of people's aesthetics, a variety of new building materials

materials and decorative materials continue to emerge.

People's living environment has also been improved.

But while people are enjoying all this,

they also

can't ignore the pollution of the living environment caused by building materials and decorative materials as well as the harmful effects on human health.

People's living environment is surrounded by building materials and decorative materials and the external environment separated from the tiny environment, these materials

Some of the components of the indoor environmental quality has a great impact.

For example,

some stones and bricks contain high background radium,

which can metamorphose

into highly radioactive radon,

which can cause lung cancer.

Many organic synthetic materials can release many volatile organic substances into the indoor air. For example, formaldehyde, benzene, toluene, ethers, esters and other pollution of indoor air, some people have been detected in the indoor air

500

more than organic chemicals, of which

20

more than a cancer-causing or mutagenic effect. The concentration of these substances is sometimes not very

high,

but in their long-term combined effect,

can make the people living in the room contaminated by these volatile organic pollutants

bad building syndrome,

building-related diseases and other diseases.

Especially in buildings with air-conditioning systems,

the lack of timely removal of pollutants from the room

makes people more susceptible to these adverse reactions and illnesses.

The following is a brief description of how VOCs are used in the air-conditioning system.

Here are some common building

materials and decorative materials on the indoor environment, as well as the hazards of human health.

Inorganic materials and recycled materials

Inorganic materials for construction or decoration mean that the composition of these materials is basically inorganic chemical substances, including metal materials and non-

Metal materials are two categories. Metallic materials are steel, copper, aluminum, etc., non-metallic materials are natural stone, burnt clay products, glass,

Inorganic fiber materials, gel products. With the development of science and technology, sometimes in order to save, people on steel slag, cinder

and other waste utilization, made of bricks and other recycled building materials.

Inorganic building materials and recycled building materials are more prominent health problems is the problem of radiation. Some building materials contain

more than the national standard

r

radiation. The radioactivity of building materials varies depending on where they are sourced from. The national standard

provides that building materials

r

radiation in

20μg/h

below. For example, some people in the market main building materials

r

radiation

amount of investigation found that the cinderblock

r

radiation

25.03 μg / h

.

Some materials such as stone, brick, cement and concrete contain high background radium, which can metamorphose into radon and enter into the room through wall joints, window joints

and so on,

resulting in indoor air pollution by radon.

Radon is a highly radioactive element, and long term exposure to radon,

even at very

low concentrations, can increase the risk of lung cancer in indoor populations.

Question 5: Is pig iron an inorganic material? Why. Because there is no organic material. The main component of pig iron is iron monomers, followed by carbon monomers, all monomers, no organic matter.
