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:Where is the specialty of vermiculite?
Jiangsu, Lianyungang, Donghai County, Hebei County, Lingshou Province, vermiculite mineral is also rich! There are rich vermiculite minerals in Donghai County, especially in Baita Town, which is rich in vermiculite. The vermiculite here is not only rich, but also of good quality.
Q:Are perlite and vermiculite fertiles?
The expansion effect of vermiculite in Horticulture: vermiculite have very strong water absorption, can effectively promote plant root growth and seedling growth is stable. Provide water and nutrients necessary for plant growth for long periods of time and maintain the stability of root sun temperature. At the same time, the vermiculite can make the crops get plenty of water and minerals from the early growth stage, and promote the rapid growth of plants and increase the yield. It can be concluded that vermiculite has a relatively large fertility, at least stronger than traditional soil.
Q:Vermiculite soil and clay can be kind of meat plants collocation
The economic benefits can be added to crush a honeycomb briquet can buy in, in granular soil fleshy special, such as akadama soil, deer marsh soil, volcano stone and so on.
Q:What harm does sowing only use vermiculite to plant?
Vermiculite can also provide the crop with its own K, Mg, Ca, Fe, and trace amounts of Mn, Cu, Zn and other elements. Vermiculite has the characteristics of water absorption, cation exchange and chemical composition, so it has many functions such as fertilizer preservation, water retention, water storage, air permeability, mineral fertilizer and so on. The experiment shows that adding the expanded vermiculite of 0.5-1% into compound fertilizer can increase crop yield by 15-20%.
Q:What is the bulk density of asphalt vermiculite? Is it better to use asphalt, vermiculite or cement vermiculite when roofing?
Asphalt expanded vermiculite products are made of expanded vermiculite and hot asphalt by mixing, pouring, molding and pressing.Asphalt expanded vermiculite products have light weight, heat preservation, heat insulation, sound absorption, hydrophobic and corrosion resistance. Can be used in cold storage projects, industrial pipelines, building roofing insulation materials. The bulk density of asphalt expanded vermiculite products is about 300 ~ 400kg/m3.
Q:Is it OK to mix vermiculite and perlite in the vegetables grown in the soil?
Yes, rattan month and pot wood rose can be cut. Generally speaking, according to cuttings, there are two ways to choose: one, hardwood cuttings, also known as dormant branches inserted. Field cultivation of rose leaves in autumn, until the germination of the spring, the use of 1 years of cutting branches. Winter branches are usually pruned, with no pests, woody shoots, and plump shoots for cuttings. Cuttings 10~12 cm long, with 3~4 buds. In the dry, place for shelter Xiangyang high bed for slotting machine, land leveling after mulching, and then cutting, in order to improve the soil temperature, promoting rooting. The cuttings into the soil 1/2~2/3, keep the 1 buds exposed soil surface, inserting length of 8~10 cm, per square meter 100~140 strain. Plug in the Yangtze River Basin, probably in late February roots, March shoot new shoots. It can be transplanted in 5~6 month. Hardwood cuttings such as in October, before winter roots, germination in spring, good seedling quality.
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:What are the characteristics of vermiculite on flowers?
Vermiculite can keep warm and moisturize, but vermiculite doesn't have the nutrients needed by plants, so you need to add fertilizer occasionally.
Q:What is vermiculite?
Vermiculite (Vermiculite), Ca (Mg), 0.3-0.45 (H2O), n{(Mg, Fe3, Al), 3[(Si, Al), 4O12] (OH), 2}The name of Vermiculite from Latin, with a "worm" and "worm trail shape". Vermiculite were heated to 200 DEG C to 300 suddenly will be along the c axis of the crystals to produce worm like peeling, which it acquired its name. Vermiculite is a layered structure containing magnesium aluminum water Portland secondary metamorphic minerals,The shape of raw ore is similar to mica, which is usually made up of black (gold) mica by hydrothermal alteration or weathering. Because of its heating and water loss, it is bent when expanding, and the shape is similar to that of leech, so it is called vermiculite
