Q:The effect of vermiculite as a medium on plants
Vermiculite is through high temperature baking, has the advantages of good water absorption, heat insulation, moisture, loose, light, this is the advantage after mixing, but also conducive to the rooting and growth of plants.
Q:Main applications of expanded vermiculite
In the newly emerged soilless cultivation technology, it is an essential raw material. Spread the expanded vermiculite on the roof, it can play a very good insulation effect, so that the house is warm in winter and cool in summer. A partition plate of high-rise building with vermiculite brick masonry, can sound insulation, fire prevention moisture-proof effect, and can reduce the floor load. Vermiculite and a suitable amount of insulation glue can be made into insulation board. At present, vermiculite is also used in medicine, health, animal feed and other industries.
Q:How much should the ratio of soil vermiculite to perlite be?
The cake, put the pelvic floor relatively okay ~ ~ to let the seedlings have a process of adaptation ~ ~ ~ I now add more perlite. Vermiculite feels the only use now is probably: when you plant seeds, sprinkle a thin layer over the surface... Very few in the soil.. It feels less breathable ~ as I just how to perlite
Q:What is vermiculite? What's the use of it?
The high temperature roasting of vermiculite ore can make the volume expand rapidly 8-20 times, and the specific gravity after expansion is 130-180kg/m3. It has a strong thermal insulation performance.
Q:What is incubation vermiculite and how it is used?
Vermiculite is a natural, non-toxic mineral that expands at high temperatures. It is a relatively rare mineral, belonging to silicates. Its crystalline structure is monoclinic, and it looks like mica from its appearance. Vermiculite is produced by hydration of certain granite. It is commonly produced with asbestos. Because vermiculite has the ability of ion exchange, it has a great effect on the nutrition of the soil.
Q:What is the theoretical and practical significance of adding three yuan purifier pad with vermiculite?
The theory of specific field has its specific concept, category and research paradigm. Only in the same concepts, perspectives and paradigms... And library locations. At the same time, it is important to make a study note and extract the important points and...Different shapes of components can be produced according to different requirements. By adding other additives or surface treatment agents, you can shrink less, do not absorb moisture in the air, and have good stability. It is suitable for making auto parts. 8) manufacture of new construction and decoration materials...Significance。 A great deal of work has been done both at home and abroad on the purification of yellow phosphorus tail gas and the development of yellow phosphorus exhaust gas, in which the southwest chemical industry has reduced the transportation cost and extended the service life of the landfill site. Such as cars, cans, plastic bottles and so on, usually first pick...
Q:What is the bulk density of asphalt vermiculite? Is it better to use asphalt, vermiculite or cement vermiculite when roofing?
Cement vermiculite, that is, cement and vermiculite mixed together, construction needs water at the scene, solidification formed after a light insulation material, usually used for roofing or ground insulation. The bulk density of cement vermiculite is about 600-800KG/m3.If only from the bulk density angle, the asphalt vermiculite certainly is better than the cement vermiculite
Q:Coconut brick soil permeability is good, that also need to add vermiculite, perlite?
Are expanded perlite and expanded vermiculite the same substance?What's the difference between them? What's the matter?
Q:How to use flower vermiculite?
Vermiculite is a mica material formed when the silicate material is heated at high temperature. During the heating process, the moisture content of the silicate material is rapidly lost and expanded, and the volume after expansion is 15 times the original volume. Thus, the aeration pore and water holding capacity of the substance are increased.
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.
