Q:How many methods of expansion of vermiculite?
. The expansion of vermiculite was fine particle structure of thin laminations, filled with air, so they have low thermal conductivity, thermal expansion coefficient of vermiculite tears is generally 0.07-0.07w/m.k, under normal temperature condition (temperature range of 20-30 degrees) technology performance of thermal conductivity and particle size and bulk density of expanded vermiculite between. Product specifications. The refractoriness of expanded vermiculite is 1300-1350 degrees, and the safe service temperature is -30 ~ 1100 degrees. Swelling vermiculite, some moisture absorption rate is small, in the relative humidity of 100% in the environment, after 24 hours, the moisture absorption rate is generally not greater than 2%.
Q:Main applications of expanded vermiculite
Vermiculite is a product of many products of vermiculite vermiculite. He is non-metallic mineral products after the vermiculite ore after calcination processing. The proportion of its very light one side only 80-100 kilograms. It has good air permeability. Moisture and insulation. In vermiculite in the greenhouse, with osteoporosis the soil, good air permeability, water absorption ability, the characteristics of small changes in temperature, is conducive to the growth of crops, but also can reduce the amount of fertilizer.
Q:What is vermiculite steel tile?
The characteristics of the steel roof system and fastening can reduce the design cost, building material costs and installation costs; water treatment costs can save the characteristics of surface self waterproof structure layer; characteristics of durability can save all cleaning and maintenance costs.
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: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:Can you put vermiculite in the fish tank?
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 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:Coconut brick soil permeability is good, that also need to add vermiculite, perlite?
Coconut and coconut shell powder brick brick is flowers, gardening in the excellent new excellent soilless culture, compression block with high temperature and high pressure treatment is made, free of pests, clean, environmental protection, the compression ratio is 800-900%, the matrix a coconut with about 8-9 liters. Before use, should be disposed of coconut husk, with hard water soaking in north of China, the dissolved coconut husk containing sodium chloride, rinse with pure water, until the leaching out of the water EC value and a EC value close to pure water so far.
Q:What is the difference between perlite and vermiculite and orchid stone?
And for cuttings, they are not inferior to sand, and the greater advantage is that they are sterile. However, the disadvantages of perlite and vermiculite are that the physical condition will change over time, and the permeability and drainage will decrease. Perlite can pinch into powder, some will be broken in the process of transportation and produce some powder.
Q:Are expanded perlite and expanded vermiculite the same substance?What's the difference between them? What's the matter?
Vermiculite: Color: yellow, yellowish brown. Vermiculite after calcination, the volume can be expanded by several times, the volume expansion after the vermiculite called vermiculite.
