Q:How many methods of expansion of vermiculite?
When the expanded vermiculite is in the drying state, it has good frost resistance. When the degree of -20 is 15 times, the particle size of the expanded vermiculite is invariable. Expanded vermiculite is inorganic, so it is free of fungus, does not decay, does not deteriorate, and is not easily bitten by moth eaten mice. Expanded vermiculite is alkali resistant and non acid resistant, so it is not suitable for acid etching.
Q:Where is the specialty of vermiculite?
China's vermiculite is widely distributed, but mostly distributed in northern China, mainly Xinjiang, Hebei, Inner Mongolia, Liaoning, Shanxi, Shaanxi and other provinces and autonomous regions. They are also distributed in Sichuan, Henan, Hubei, Gansu and other provinces.
Q:Can vermiculite be used for making flowers?
Because vermiculite has the ability of ion exchange, it has a great effect on the nutrition of the soil. In 2000, the total output of vermiculite in the world exceeded 500 thousand tons. The major producers are China, South Africa, Australia, Zimbabwe and the United states.
Q:Vermiculite, soilless cultivation, horticulture, vermiculite, the use of coarse?
There are two conventional specifications for raising vermiculite: 1-3mm (seedling raising, horticulture, vermiculite), 2-4mm (seedling raising, vermiculite), and various types of seedling vermiculite according to customer requirements. Seedling vermiculite is made of expanded vermiculite specially made.
Q:Baht, activated carbon, vermiculite, these three often harmful to the body?
Activated carbon is a porous substance, inert in the air, not only harmful to the body, but also the suspension of air, harmful gases.
Q:What are the main ingredients of vermiculite fireproof board?
Vermiculite (Vermiculite) (Mg, Ca) 0.3-0.45 (H2O) n{(Mg, Fe3, Al) 3[(Si, Al) 4O12] (OH): 2} is a layered structure containing magnesium aluminum silicate water secondary metamorphic minerals, ore shape like mica, usually consist mainly of black mica (gold) by heat liquid alteration or weathering, because of the heat loss during the expansion was a deflection shape similar to the shape of leech, called vermiculite.
Q:How does vermiculite make a roof insulation?
1, the use of mechanical agitation, the expansion of vermiculite particles are very damaged, and sometimes can reach 50%, and easily with the mixing tube bonding, it is not appropriate to use. Using artificial mixing, the first water and cement quantitative uniform into cement slurry, cement slurry and then evenly pour in vermiculite quantitative with bucket, pour with mix, mixing evenly.2, roofing laying insulation layer, should take "sub warehouse" construction, each warehouse width of 700 ~ 900mm. It can be separated by wood board, or steel bar ruler can be used to control width and laying thickness.
Q:What are the characteristics of vermiculite and gold yellow expanded vermiculite?
Expanded vermiculite has excellent heat insulation, sound insulation, insulation, flame retardancy, and other properties.
Q:How can the new vermiculite be treated?
