1. Main components and formation process

Main ingredients: The vermiculite tablet is mainly made of expanded vermiculite as the main raw material. Vermiculite is a natural, inorganic, and non-toxic mineral that rapidly expands at high temperatures of 800-1000 ℃, increasing in volume by 8-20 times, forming expanded vermiculite. Expanded vermiculite has many small flakes with numerous air gaps between them. In addition to expanding vermiculite, a certain amount of adhesive (such as organic resin or inorganic binder) will also be added to bond the vermiculite flakes together. Formation process: Mix expanded vermiculite and adhesive in a certain proportion, place them in a mold, and then press and cure them. During the pressing process, a certain amount of pressure is applied to tightly arrange the vermiculite flakes, and the adhesive can firmly bond the vermiculite into a plate-like structure after curing, thereby forming vermiculite slabs.

2. Performance characteristics

Excellent thermal insulation performance: The thermal insulation performance of vermiculite is very outstanding. This is mainly because there are a large number of air gaps inside, and air is a good thermal insulator, making it difficult for heat to conduct through these gaps. In terms of building insulation, the use of vermiculite can effectively prevent the exchange of indoor and outdoor heat, reduce building energy consumption, and improve energy utilization efficiency. For example, using vermiculite for insulation on the roof and exterior walls of a house can significantly reduce the cooling load in summer and the heating load in winter. Good fire resistance: Hirudite is a fireproof material with a high fire resistance limit. Vermiculite itself is an inorganic mineral, non combustible, and does not produce toxic or harmful gases at high temperatures. In the event of a fire, vermiculite can act as a barrier to flames and heat, buying time for personnel evacuation and firefighting, and enhancing the fire safety of buildings. Sound absorption and noise reduction function: Due to the relatively loose structure of vermiculite, there are many small gaps and channels inside, and sound will continuously reflect and refract in these gaps during propagation, gradually attenuating energy. Therefore, vermiculite can effectively absorb and reduce sound, and is used for interior walls and ceilings of buildings, reducing indoor noise and creating a quiet environment. Good chemical stability: vermiculite tablets have good tolerance to most chemicals. It can resist the corrosion of chemical substances such as acid and alkali. In some chemical industrial environments or places with the possibility of chemical pollution, vermiculite can maintain its stable performance and will not deteriorate or be damaged due to contact with chemical substances. Lightweight: The density of vermiculite is relatively small, and compared to traditional building materials, it is lighter in weight. This makes it more convenient to install and does not impose excessive burden on the structure of the building. At the same time, it can also reduce transportation costs and improve transportation efficiency during the transportation process. Green and environmentally friendly: The main raw material, vermiculite, is a natural mineral that is non-toxic and harmless, and does not produce any harmful substances to the environment during production and use. In addition, vermiculite slabs also have the characteristic of being recyclable, which is in line with modern environmental protection concepts.

3. Application Fields

In the field of building insulation, it is widely used for external wall insulation, roof insulation, floor insulation, etc. of buildings. In some buildings with high insulation requirements, such as cold storage and constant temperature and humidity laboratories, vermiculite slabs play an important role. Sound absorption engineering: used for sound absorption treatment in places such as concert halls, conference rooms, cinemas, etc. By installing vermiculites on walls and ceilings, the acoustic environment can be effectively improved, and the clarity and comfort of sound can be enhanced. Fire Protection Engineering: Used as a fire separation material for firewalls, fire doors, and other parts of buildings to enhance their fire resistance. At the same time, vermiculite is widely used in some industrial fire prevention facilities. Horticulture field: In horticulture, vermiculite can be used as a soil amendment and plant growth substrate. Due to its good water retention and breathability, it can provide a suitable growth environment for plants.
