"What kind of garbage are you?" Recently, it has become a popular joke on the Internet. This is not a satire, but a dialogue that people have been playing every day since the garbage classification pilot. Faced with various types of household waste, people are already feeling dizzy. So, how can we better classify the waste generated by construction and decoration?

What is construction waste?

Definition

Simply put, construction waste refers to the waste soil generated during people's construction activities such as demolition, construction, decoration, and restoration Waste concrete The general term for waste materials such as bricks and stones.

2. Classification

Construction waste can be divided into various types, and according to the source of production, it can be classified as engineering waste Decoration waste Demolition of garbage Engineering mud, etc. Classified by composition, construction waste can be divided into waste soil, concrete blocks, crushed stones, brick and tile fragments, waste mortar, mud, asphalt blocks, waste plastics, waste metals, waste bamboo and wood, etc.

3. Handling

Construction waste mainly consists of concrete blocks and waste plastics, so most of the construction waste is recyclable. However, it is worth noting that there are also harmful substances in construction waste, so a small amount of construction waste belongs to harmful substances. How to handle it specifically, based on the specific garbage.

What is renovation waste?

Definition

Decoration waste refers to various types of waste generated during the interior decoration of a house. All waste generated from the beginning to the completion of the decoration process, such as cut waste bricks, cement mortar, cement mortar, and waste materials, as well as waste boards left after woodworking, are all part of the decoration waste.

2. Classification

Decoration waste belongs to a type of construction waste, which is mainly divided into scrap metal Recyclable waste such as paper packaging materials; Bricks and stones concrete. Mineral waste such as mortar; Waste sofas, beds, wood waste, sawdust, and other mixed garbage, as well as hazardous waste such as waste paint, glue, and light tubes.

3. Handling

Decoration waste can be roughly classified into two types: recyclable waste and hazardous waste. Recyclable waste mainly refers to plastic, soil, wood and other waste generated during decoration, while hazardous waste refers to paint generated during decoration Materials with residual harmful chemicals such as glue should be classified as hazardous substances.

What is the difference between construction waste and decoration waste?

1. Different sources

The main difference between construction waste and decoration waste is the source of the waste. Construction waste is a series of garbage generated during the construction process; Decoration waste is the waste generated during indoor decoration, so the sources of waste vary greatly.

2. Different classifications

Decorative waste is a part of construction waste. It can be said that decorative waste is construction waste, but construction waste is not entirely decorative waste. Therefore, the scope and categories of construction waste are broader, while decoration waste only refers to all the waste generated from indoor decoration, and the categories are only a part of it.

3. Different processing methods

After sorting or crushing construction waste, most of it can be recycled and reused. Just like steel bars. After recycling scrap iron wire, scrap electrical wire and other metals, they can be processed into various specifications of steel. After the generation of decoration waste, units and individuals should place the decoration waste in a fixed place set up by the person in charge of decoration waste management, which can be recycled and separated from harmful waste.

From the above, it can be seen that although construction waste and decoration waste are both engineering waste generated during the construction process, they are very different in terms of their sources and subsequent disposal methods. Therefore, the waste generated from building decoration must be treated according to specific waste.

From the above, it can be seen that decoration waste is a specific type of construction waste, including decoration waste Demolition of house garbage Engineering waste soil Engineering mud The relationship between abandoned concrete blocks and others is not difficult to understand.

Wind sorting machine is a traditional garbage sorting method widely used in various solid waste treatment and garbage resource recycling fields. In the process of solid waste treatment and resource recycling, air separators are almost necessary sorting equipment.

The main principle of a wind separator is to use aerodynamic principles to reduce the weight of materials under the combined action of controllable positive and negative pressure airflow Separation of small and heavy substances. Light materials are output through the light material discharge conveyor, while heavy materials cannot support gravity settlement and output on the heavy material discharge conveyor.

Common sorting materials:

Light substances such as plastic bags, woven bags, paper sheets, and heavy materials (mixtures with different density ratios)

Wind sorting machines are generally used for sorting household waste, building decoration waste, waste paper, plastic, and metal

Characteristics of wind selection machine:

1： Negative pressure sorting, no dust leakage.

2： Wind speed regulation to meet different properties of materials, including high humidity materials.

3： Adopting modular design, with good performance and low maintenance costs.

4： No need to configure wind power system and filtration system.

5： Choose the double drum separation type, which can be divided into three components: light, medium, and heavy.

6： There are few vulnerable parts, and the downtime for maintenance is very low.

7： Integrated design of electronic and mechanical control, plug and play on installation site.
