Q:What can vermiculite do?
Moisturize, improve soil texture, and increase breathability.
Q:Where is the specialty of vermiculite?
Vermiculite in China Xinjiang, Russia, Zimbabwe, Australia, Kola Peninsula and South Africa have produced in the United states.
Q:Cymbidium can use vermiculite or vermiculite mixed pine? Peanut shell?
In addition, vermiculite can also provide the crops with K, Mg, Ca, Fe and trace amounts of Mn, Cu, Zn and other elements. Vermiculite has the characteristics of water absorption, cation exchange and chemical composition, so it has many functions such as fertilizer preservation, water retention, water storage, air permeability, mineral fertilizer and so on.
Q:What is vermiculite? What's the use of it?
The use of vermiculite has been widely used in the fields of construction, metallurgy, petroleum, shipbuilding, environmental protection, heat preservation, heat insulation, insulation, energy saving, gardening and so on. Animal husbandry: expanded vermiculite has unique structural and surface properties, as well as non-toxic, sterile and chemically inert. It can be used as a carrier, an adsorbent, a fixative, and a feed additive.
Q:What can vermiculite dos?
The expanded vermiculite is widely used, but its main purpose is still to be used as building material.
Q:Are perlite and vermiculite fertiles?
The expansion effect of vermiculite in Horticulture: vermiculite have very strong water absorption, can effectively promote plant root growth and seedling growth is stable. Provide water and nutrients necessary for plant growth for long periods of time and maintain the stability of root sun temperature. At the same time, the vermiculite can make the crops get plenty of water and minerals from the early growth stage, and promote the rapid growth of plants and increase the yield. It can be concluded that vermiculite has a relatively large fertility, at least stronger than traditional soil.
Q:Vermiculite soil and clay can be kind of meat plants collocation
The economic benefits can be added to crush a honeycomb briquet can buy in, in granular soil fleshy special, such as akadama soil, deer marsh soil, volcano stone and so on.
Q:What are the main ingredients of vermiculite fireproof board?
Vermiculite is a kind of layered magnesium silicate, which is similar in shape to mica. Because it is bent when it is hot and inflated, it is similar to leech, so it is called vermiculite. The utility model has the advantages of heat insulation, heat resistance, frost resistance, antibiosis, fire protection, sound absorption and the like
Q:Does the vermiculite contain alkaline? Can it be planted with azalea?
Vermiculite is a neutral mineral, not alkaline. Cultivated azaleas are not suitable for vermiculite. In plant cultivation, vermiculite can be used as soil conditioner, vermiculite has the characteristics of loose soil, good permeability, strong water absorption and little temperature change. The Rhododendron culture soil requires good aeration and humus rich acid soil. The value of pH is 5.5 to 6.5.
Q:How much cement does the vermiculite heat preservation layer need?
Cement and expanded vermiculite, cement should be no less than 325, usually choose 425 ordinary Portland cement. The volume ratio of cement and expanded vermiculite is generally 1:5, which is economical and reasonable. Cement and sand aspect than the general 1:1. Site inspection method: mix the cement paste with fine powder and knead it by hand.
