vermiculite Fire Brick: For Hot face and Back-up Insulation up to 1100 degree celsius( 2012 degree F)

 Durable Decorative Fireproof Stove/Fireplace Vermiculite Brick Panel  

 

A Vermiculite panel is a good choice as a fireplace panel because  they not only hold heat in, but they also reflect the heat so that the fireplace  is even more powerful. The material vermiculite is fast becoming very popular to  use in fireplaces because it can be made in a mold to fit almost any size,  pattern or shape of the interior of a fireplace. They are also considered to be  an affordable solution as a replacement fireplace panel and will help to keep  the fireplace running optimally for years to come. 

 

Characteristics:

  1. A1 Grade non-combustible fire rating.

  2. Heat insulation and preservation.

  3. Sound insulation.

  4. Moisture adjustment.

  5. Environment friendly, non-toxic and zero radioactivity, non-asbestos.

  6. Easy to cut and shape with woodworking tools.

Q:How to apply the quota of cement and vermiculite insulation layer?
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:Water resources are faced with the crisis of shortage and pollution. Can perlite and vermiculite be used for water treatment?
Perlite and vermiculite are not readily available, and need to be processed by corresponding processing equipment with a certain process. Generally, perlite needs not fine powder, which can be called coarse powder, and some areas are called coarse sand.To set the perlite processing equipment according to the final requirements, some broken process need to be broken by the jaw crusher, and then if the finished products need a lot of powder grinding processing by perlite mill, can achieve a finished product; if the product requires a large amount of coarse sand, with a jaw crusher finely, with efficient crusher, after perlite through the sieve screening, can get the corresponding size of perlite particles.
Q:Water resources are faced with the crisis of shortage or pollution. Can perlite and vermiculite be used for water treatment?
With the development of industrialization, water resources are facing the crisis of shortage and pollution. Researchers in various regions have launched researches to meet the new requirements of the state for wastewater treatment.
Q:What are the main ingredients of vermiculite fireproof board?
Vermiculite is a kind of layered magnesium silicate, which is similar in shape to mica. Because it is bent when it is hot and inflated, it is similar to leech, so it is called vermiculite. The utility model has the advantages of heat insulation, heat resistance, frost resistance, antibiosis, fire protection, sound absorption and the like
Q:How does vermiculite make a roof insulation?
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: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:What are the characteristics of vermiculite and gold yellow expanded vermiculite?
Expanded vermiculite has excellent heat insulation, sound insulation, insulation, flame retardancy, and other properties.
Q:Can vermiculite take the place of soil? Is it okay to plant seeds directly in vermiculite?
Vermiculite can not replace soil, vermiculite, good air permeability, but no growth of plant nutrients, only as seed germination, seed germination time after transplanting.
Q:Please describe the peat, vermiculite, perlite, bark, sand characteristics and application in the garden?
Peat, peat and peat. It is the ancient marshy plants are buried in the ground, in the flooding and lack of air conditions, decomposition of organic matter is not completely special. The peat in Northeast China is high and cold area. The content of nitrogen and ash in peat is low, slightly acidic or strong acidity, pH value is 5.0---5.9, EC value is less than 1, and water holding capacity is high.
Q:How much cement does the vermiculite heat preservation layer need?
The cement vermiculite insulation layer is a heat preservation layer formed by solidifying cement, vermiculite and water, and the cement vermiculite is made by mixing the cement and the vermiculite according to the volume ratio 1:5. The bulk density is about 350KG/ cubic meters.
