Product Description

Raw vermiculite ore for raw vermiculite flake fire retardant materials fire-resistant coatings unexpanded vermiculite 

Product Description

Vermiculite is a natural, inorganic, non-toxic mineral that will expand under the action of high temperature. Vermiculite can be divided into raw ore vermiculite and expanded vermiculite according to the stage. According to the color classification, it can be divided into golden yellow vermiculite and silver white vermiculite. After the raw ore vermiculite flakes are roasted at high temperature, their volume can rapidly expand several times to tens of times. The expanded vermiculite is called expanded vermiculite. Expanded vermiculite has good air permeability and water retention, and is rich in mineral elements. It is used as a medium for horticulture and agriculture and has a good role in promoting plant growth. And expanded vermiculite has strong thermal insulation performance. Vermiculite is mainly used in agricultural seedlings, flowers, and trees, as the main raw material for culture substrates, and secondarily used in industrial friction materials, refractory materials, and construction industries.
 

Vermiculite is one of the lightest minerals in the world. The vermiculite flakes have formed the shape above after being heated and expanded in a high-temperature kiln at 1200 degrees Celsius. A small vermiculite like this contains over 12000 pores, each of which has a strong adsorption effect. Under high temperature roasting, raw vermiculite forms granular expanded vermiculite, which is lightweight, porous, has a high melting point, and low thermal conductivity. It is a good insulation material, mainly used as a building insulation material. A 15cm thick cement vermiculite slab is burned at a high temperature of 1000 ºC for 4-5 hours, and the back temperature is only about 40 ºC. The 7cm thick vermiculite plate was welded with a flame mesh and burned at a high temperature of 3000 ºC for five minutes. The front melted and the back was held by hand without feeling hot. So it is very suitable for making high-temperature insulation materials.
 

The vermiculite raw ore material extracted from the vermiculite mine is broken and classified, which includes the crusher of the raw vermiculite, etc., and divided into vermiculite flakes of different diameters.
