  Vermiculite for Insulation

Product Description


Thermal conductivity is small, is a good insulating material. Good quality of expanded vermiculite, the highest temperature can reach 1100 ℃. In addition, expanded vermiculite has good electrical insulation. Expanded vermiculite is widely used in insulation, fire prevention materials, seedlings, flowers, trees, friction materials, sealing materials, electrical insulating materials, coatings, plate, paint, rubber, refractory materials, hard water softener, smelting, construction, shipbuilding, chemical industry, etc.

Q:How to apply the quota of cement and vermiculite insulation layer?
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.
Q:What can vermiculite i do?
The bulk density of horticultural vermiculite is 130-180 kg / cubic meter, which is neutral to alkaline (ph7-9). Vermiculite can absorb up to 500-650 liters of water per cubic meter of water. After steam disinfection, can release the appropriate amount of potassium, calcium, magnesium.
Q:The role of vermiculite
After mining, ore vermiculite rolling, screening, puffing and other physical processes after thermal insulation, sound insulation, waterproof and insulation is the main raw material and filling material decoration materials and other industries, has been widely used in gardening, warm baby fever, posts, Sachet, construction, metallurgy, oil, chemical, shipbuilding practice, etc. industrial.
Q:Is vermiculite helpful to flowers?
Vermiculite is not a good thing. It does not contain any nutrients and easily atomized powder, after the soil has poor permeability, easy to cause rot. Usually it is only suitable for cutting.
Q:Can vermiculite be used for making flowers?
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.
Q:Iron powder. Water. Activated carbon. Vermiculite. Mineral water absorbent resin. After contact with air to human body harmful?
Iron powder will oxidize when it meets air, but it is harmful to people's health
Q:Can ordinary small stones instead of vermiculite be used as Camellia cuttings?
Of course not. Vermiculite is used in horticulture as its main function is to increase the aeration and water retention of soil (medium). Because of its fragile, with the use of time to extend, easy to medium dense and lost ventilation and water retention, so coarse vermiculite better than the use of long time, and the effect is good.
Q:What does vermiculite look like?
Vermiculite is a silicate material, expanded at 800~1000 degrees high temperature. Different types of building materials stores are available.
Q:Can planting soil sand be replaced with perlite or vermiculite?
Rotten leaves are made of fallen leaves and hay. High humus content, strong water retention and good permeability are one of the main materials for preparing cultivated soil.There are two kinds of mountain mud, black mud and Mount Huangshan mud. A long accumulation of fallen leaves from mountain trees. Heishan mud is acidic and contains more humus. The Mount Huangshan mud is also acidic and contains less humus.Peat soil is carbonized from peat moss. Due to the different stages of formation, Brown Peat and black peat are divided into two types. Brown Peat is rich in organic matter and acidic. Black peat contains more minerals, organic matter is less, and it is slightly acidic or neutral.The rice chaff ash after burning into ash shell, slightly alkaline, potassium, water permeability.
Q:Vermiculite in the end what color is good, my how like false?
Because vermiculite has the ability of ion exchange, it has a great effect on the nutrition of the soil. In 2013, the world's total output of vermiculite exceeded 500 thousand. The major producers are China, South Africa, Australia, Zimbabwe and the United states. Vermiculite is a kind of clay mineral similar to montmorillonite, which is a layered structure of silicate.
