Product Description:

1.Company Introduction Company Introduction:

Our company deal with Vermiculite for over 15years. We has being exporting vermiculite to Japan,Korea,Middle east,USA,Russia market,our capacity per year is around 6000-1000Ton,with compatitive price,best service,accept quality,gets high reputation from our old and new customers.

2.Vermiculite Introduction:

Our vermiculite, we have both crude vermiculite and exfoliated vermiculite in two types: one is Silver-grey type ( Fe2O3 content around 5-8%, similar with South Africa vermiculite); the other type we call Golden-yellow type (Fe2O3 content around 16-23%, similar products with India and Australia).The white type mainly used in refractories/insulations, the golden yellow type mainly used in agriculture and horticulture. If used for agriculture and horticulture, we suggest you use golden vermiculite, because its PH is 6.5-7.2, for silver gray vermiculite,its PH is 8.5-9.5, that's to say, compared with silver vermiculite, golden vermiculite is more neutral. In Japan, Korea market, our customers choose golden vermiculite used for agriculture and horticulture.

Q:How to apply the quota of cement and vermiculite insulation layers?
Vermiculite is a kind of hydrate, which is blocky, flaky and granular. It is the product of weathering and alteration of natural mineral such as biotite. The interlayer water molecule is ignited at high temperature, and the volume is increased by 18-25 times. Rich in nitrogen, phosphorus, potassium, aluminum, iron, magnesium, silicate and other ingredients. Vermiculite has higher layer charge number, so it has higher cation exchange capacity and stronger cation exchange adsorption capacity. Characteristics: light weight, and good adsorption properties, not decay, can be used for 3-5 years (unlike the humus, coconut shell, clothing and other perishable).
Q:How many methods of expansion of vermiculite?
Expanded vermiculite is vermiculite as raw material, after drying, crushing and roasting, the volume of short fairy in a short period of time increases rapidly, expanding (6-20 times) and becoming a kind of golden granular material. With light weight, small thermal conductivity, fire protection, corrosion resistance, chemical stability, non-toxic, tasteless and so on. The bulk density of expanded vermiculite is about 80-180kg per cubic.
Q:The role of vermiculite
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.
Q:Expanded vermiculite with expanded vermiculite
Baixin "brand expansion thermal tears coefficient of vermiculite is generally 0.07-0.07w/m.k, under normal temperature condition (temperature range of 20-30 degrees" letter "brand) technology performance expansion coefficient of heat conductivity and the relationship between particle size and bulk density of vermiculite as shown in the product specifications. "Letter" brand of expanded vermiculite refractory for 1300-1350 degrees, the safe use of temperature -30 to 1100 degrees "letter" brand. 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%. "Letter" in the dry state, vermiculite, has good frost resistance, at -20, after 15 times of freeze-thaw, the grain size composition unchanged. 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. "Shenbao" brand expanded vermiculite alkaline not acid and therefore should not be used for acidic erosion at.
Q:What can vermiculite dos?
In the US 1986 consumption structure, expanded vermiculite used as mortar and cement premix and lightweight concrete aggregate accounted for 52%; the United Kingdom accounted for 40% of concrete, wall mud and cement coagulants.
Q:What are the main ingredients of vermiculite fireproof board?
Vermiculite fireproof board is a new kind of inorganic material. It is made of expanded vermiculite as main raw material and mixed with a certain proportion of inorganic binder.
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:Can planting soil sand be replaced with perlite or vermiculite?
Planting and culturing soil sand can be replaced by perlite or vermiculite. The sand of the river is mainly porous and permeable. Perlite or vermiculite itself has more pores, and the effect is better than that of dense sand. Pay attention to the choice of larger particles of vermiculite, otherwise the effect is worse.
Q:Vermiculite in the end what color is good, my how like false?
Usually from biotite to hydrothermal alteration or weathering. It sometimes appears as large biotite (this is the biotite illusion of vermiculite) and sometimes becomes slightly soil like. When the vermiculite is heated to C, it expands 20 times and bends. This is a bit like vermiculite leech (Hirudo, commonly known as the leech) so it has such a name. Vermiculite is usually brown, yellow, dark green, oil like luster. When heated, they turn gray. Vermiculite can be used as building material, adsorbent, fireproof insulating material, mechanical lubricant, soil amendment, etc..
Q:What material is vermiculite?
Vermiculite is a natural, non-toxic mineral that expands at high temperatures. It is a relatively rare mineral, belonging to silicates.
