Q:What does cement or vermiculite mortar refer to?
Laying method of cast-in-place cement vermiculite thermal insulation layer: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.3, because of swelling vermiculite faster water absorption, construction, it is best to transport raw materials to the laying site, with mixing shop, to ensure the water cement ratio accurate and quality of the project.4, the heat insulation layer of the virtual thickness is generally 1.3 times the design thickness (not including leveling layer), after laying with wooden clapper (wood crab) beat solid, smooth to the design thickness. The bedding plane of the expanded vermiculite particles should be parallel with the laying plane as possible as possible.5, cement, vermiculite pulp compaction, smooth, should immediately wipe leveling layer, both without scoring two stages of construction. The mixing ratio of leveling mortar is 42.5 cement: coarse sand: fine sand, =1: 2: 1, and the consistency is 7 ~ 8cm (porridge shape).6, leveling layer after wiping, in general circumstances may not be sprinkler maintenance.7, the overall insulation layer should have a smooth surface. The smoothness of the use 2m straightedge check, the gap between the ruler and the surface of the insulation layer; when the insulating layer directly set the waterproof layer, should not be greater than 5mm; such as the leveling layer on the insulating layers, should not be greater than 7mm, the gap only allows smooth change.
Q:Vermiculite, soilless cultivation, horticulture, vermiculite, the use of coarse?
Vermiculite is a kind of mica material which is formed when the silicate material is heated at high temperature. In the course of heating, water loses rapidly and expands, and the volume after expansion is equivalent to 8-20 times of the original volume. Thus, the aeration pore and water holding capacity of the substance are increased. 2. the density of vermiculite was 130-180 kg / cubic meter, and it was 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: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 can vermiculite do? What's the use?
Vermiculite is a natural, inorganic, non-toxic mineral that expands at high temperatures. It is a relatively rare mineral, belonging to silicates.
Q:Can plant nursery substrates be made with plant ash and perlite and vermiculite? Seek expert advice
You can buy preferred horticultural perlite, super!
Q:Can you put vermiculite in the fish tank?
Vermiculite has been widely used in construction, metallurgy, petroleum, shipbuilding, environmental protection, insulation, heat insulation, insulation, energy saving and other fields.
Q:How long is the service life of the special vermiculite for incubation? How often do you change it?
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:Quality grade classification of vermiculite
Grade 1: vermiculite has large blades that can not be split into thin sheets. The color is brass, bronze or light green, pearl or fat luster, calcined into golden yellow, vermiculite volume expansion more than 8 times.Two grade: vermiculite leaves larger, not easy to split, peeled into a full sheet. The color is dark brown, brass and green, pearl luster or glass. After calcination, the volume of vermiculite expanded by 6 - 8 times.
Q:Will vermiculite be absorbed by plants?
The use of 1~2 years, you need to re replace. Because vermiculite will be natural weathering broken, and if continue to use, the advantages of good ventilation will become poor ventilation shortcomings.
Q:Chinese rose with 6 days after the germination of vermiculite cuttings, is false living?
In order to avoid the emergence of "false living" phenomenon of rose cutting, first of all, when choosing cuttings, we can not choose the branches that have sprouted buds as cuttings. Especially in the growing season with softwood cutting, we should also pay attention to select the branches of high maturity, full axillary buds and no budding branches do cuttings. If it is urgent to use the branches that have already sprouted buds as cuttings, and when the length is more than enough, we can cut off a part that has been germinating. If the short branch, may have been used to establish 1/3 germination of axillary buds will sprout or completely removed, to inhibit their growth, make the bottom axillary bud sprout. In this way, it can make it possible for the root to sprout and sprout.
