Main Usage of Vermiculite
Vermiculite is a laminar-shaped magnetic hydraulic secondary metamorphic mineral. The original ore looks like Yunmu. It is usually mainly composed of black (gold) Yunnu. It is brown, yellow, and dark green, with an oil-like luster, turning into gray after heating. Vermiculite can be widely used as architectural materials, adsorption agents, fire-resistant insulation materials, mechanical lubricants, soil-modified agents, etc.
Primary Purpose of Vermiculite
Architecture: Putting the expansion vermiculite on the top of the building can play a good thermal insulation effect so that the building is warm in winter and cool in summer. The wall panel of high-rise buildings with vermiculite bricks can play a role in sound insulation, fire prevention, moisture-proof, etc., and can reduce the load of the building.
Insulation and heat insulation: Vermiculite is used in the greenhouse, which has the characteristics of loose soil, good breathability, strong water absorption, and small temperature changes. It is conducive to the growth of crops, and can also reduce the investment of fertilizers. It is an essential raw material in the just-rising soilless cultivation technology.
Agriculture and forestry: Vermiculite can be used as a soil improvement agent. Because it has good cationic exchange and adsorption, it can improve the structure of the soil, store water and sacrifice, improve the breathability and water content of the soil, and turn acidic soil into neutral soil. Vermiculite can also play a cushion, hinder the rapid change of the pH value, slowly release the fertilizer in the crop growth medium, and allow it to use the fertilizer for slightly too much. The water absorption of vermiculite, cationic exchange, and chemical composition characteristics make it play multiple effects such as fertilizer, water preservation, water storage, breathability, and mineral fertilizer.
Gardening: Vermiculite can be used for flowers, vegetables, fruits, and seedlings. In addition to potted soil and regulator, it is also used for soilless cultivation. As the grassroots nutritional planting of potted trees and commercial seedbeds, it is particularly beneficial to the transplantation and transportation of plants. Vermiculite can effectively promote the growth of plant root systems and the stable development of seedlings. Vermiculite can make crops get sufficient water and minerals from the beginning of growth, promote the rapid growth of plants, and increase yield.
Other aspects: Vermiculite can be used as an adsorption agent, filter agent, chemical products and active carriers, sewage treatment, sewage oil pollution adsorption, cigarette filtering, and explosive density regulator.
