Q:How to apply the quota of cement and vermiculite insulation layer?
The present price is the separation of quantity and price.Here, the amount consumed. The consumption of fixed consumption is only the price of a natural machine. The corresponding "04 consumption quota" in Guizhou."Consumption corresponding to the so-called price is fixed base price, respectively, corresponding to the combination of talent prices. The corresponding books, such as "Guizhou city 08 price list", because different regions of the price list is not the sameFor example, we want to build a brick wall now 1.3 cubic meters of water mixing, Lane corresponding to the fixed quota items such as 3-1, the consumer can find the corresponding item is brick mixing.
Q:What does cement or vermiculite mortar refer to?
The cast-in-place cement vermiculite thermal insulation layer is made of expanded vermiculite as aggregate, cement as cementing material, mixing in a certain proportion and mixing with water and sand. Has the characteristics of light weight, small thermal conductivity, high strength, easy expansion of fission, delamination, economic quantity etc.. When applied to the flat surface, it can reduce the load of the surface layer, save the water consumption, reduce the cost and shorten the construction period. The utility model can be used as a heat insulating layer for cast-in-place or heat insulation layer or the like.
Q:Vermiculite is not big
Xinjiang vermiculite is produced in Xinjiang autonomous region of vermiculite, the vermiculite after roasting into silver white, different from Hebei, Shaanxi, Inner Mongolia and other places of vermiculite. Good quality, large output, welcomed by users.
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: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 can vermiculite be used instead of?
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. 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:What is incubation vermiculite and how it is used?
There is no difference between incubation vermiculite and horticultural vermiculite, all of which belong to silicate minerals. Its role in incubation and horticultural farming:1, for turtle eggs hatch, with mud and sand is more convenient, safer and more effective.2, for the transport of turtles, moisturizing buffer effect, can improve the survival rate.3, planting medium, one of the main materials, and peat, perlite and other mixed use.4. Sowing mulch.
Q:How can the new vermiculite be treated?
It depends on whether you buy vermiculite, vermiculite or swelling vermiculite. When you buy the vermiculite raw materials, you can grow flowers and mix them in the ground with the soil and other fertilizers. Expanded vermiculite is finished and can be used directly without further treatment.
Q:What are the characteristics of vermiculite on flowers?
The chemical formula of vermiculite is (Mg, Ca) 0.7 (Mg, Fe, Al), 6.0[(Al, Si), 8.0] (OH4.8H2O). Monoclinic system, usually in flakes. Brown, brown or tan. Grease gloss. Hardness 1~1.5. Density 2.4~2.7g/cm3, vermiculite calcined at 800~1000 DEG C, the volume of rapid expansion, increasing 6~15 times, high up to 30 times. The average density of vermiculite after expansion is 100~200Kg/m3, because the vermiculite which has been roasted and expanded has fine air barrier, so it has good insulation performance.
Q:What is vermiculite?
Vermiculite is a clay mineral with montmorillonite similar, layered silicate. Generally composed of biotite by hydrothermal alteration or weathering. It can sometimes appear to like coarse biotite (this is biotite vermiculite, sometimes false) have to be shaped. The fine soil vermiculite heated to 300 DEG C when it can be expanded 20 times and bent. This was a bit like a leech vermiculite (commonly known as the leech), so it has such a name. Brown, yellow, vermiculite is dark green, like oil sheen, heated grey. Vermiculite can be used as construction materials, adsorbent, fire insulation materials, mechanical lubricant, soil conditioner and so on, a wide range of uses.
