china xinjiang expanded Vermiculite
The slate is a plate made of expanded vermiculite and a certain amount of adhesive, which is hot pressed or cold pressed. The board has the characteristics of heat preservation, heat insulation and fire prevention. This product can be used in fire door cores, fireplace linings, wall materials.
Meteorite is a new type of inorganic material. It is made of expanded vermiculite as the main raw material and mixed with a certain proportion of inorganic binder. After a series of processes, it has high temperature resistance, fire resistance, environmental protection, heat insulation, sound insulation and no A board containing harmful substances. After heating at a high temperature to 1200 °C, it does not produce a gas that is harmful to human health, and the combustion performance reaches Grade A.
Meteorite is widely used in construction, shipbuilding, metallurgy, electric power, aerospace and other fields; slate can be used for furniture, firewalls, ceilings, fire vents, steel beam cladding, pipeline cladding, real fire fireplaces The lining in the middle, the partition of the wall, etc. 1. Fire door core; 2. Advanced kitchen utensils and furniture; 3. Hull sheet; 4. Fire exit and ventilation system; 5. Commercial bank, library, hotel, hotel, entertainment venue, high-end residence, ordinary residence, etc.; Kiln insulation; 7, fireplace insulation; 8, industrial insulation materials.
In agriculture, vermiculite can be used as a soil improver. Because of its good cation exchange and adsorption, it can improve the structure of the soil, preserve water and moisture, improve the permeability and water content of the soil, and make the acidic soil neutral. Soil; vermiculite can also act as a buffer, hinder rapid changes in pH, slow release of fertilizer in crop growth media, and allow for a slight excess of fertilizer without harm to plants; vermiculite can also provide crops with their own K, Mg, Ca, Fe and trace elements such as Mn, Cu, Zn. The water absorption, cation exchange and chemical composition of vermiculite play a multiple role in fat retention, water retention, water storage, ventilation and mineral fertilizer. Tests have shown that the incorporation of 0.5-1% of expanded vermiculite into the compound fertilizer can increase crop yield by 15-20%.
In horticulture, vermiculite can be used for flowers, vegetables, fruit cultivation, and nursery. In addition to potting soil and conditioner, it is also used for soilless cultivation. As a nutrient base for planting potted trees and commercial seedbeds, it is particularly advantageous for planting and transporting plants. Vermiculite can effectively promote the growth of plant roots and the stable development of seedlings. It provides the water and nutrients necessary for plant growth for a long time and keeps the temperature of the roots stable. Vermiculite can make crops get enough water and minerals from the beginning of growth to promote faster plant growth and increase yield.
