Perlite insulation board: closed-cell perlite surface melting hard shell vacuum sphere type expanded perlite is a new type of new insulation and heat insulation material widely used in the world. It is expanded by a high-temperature electric furnace and has a microsphere shape on the surface. Each particle has continuous Hardened shell, closed pores, honeycomb hollow sphere structure, compared with traditional porous open expanded perlite, the product has high strength, water absorption is quite low, only 50%-85% (conventional product is 360% -480%), closed cell ratio greater than 95%, sphericity rate 90%, particle size 0.1-1.5mm, bulk density 100-200kg/m2, resulting in a coefficient of 0.047-0.054w/mk, cylinder strength 38%-46%, fire resistant Degree 1280-1360 ° C. It is easy to disperse in cements such as refractory materials, cement, resin, water glass, gypsum, etc., especially when used in a liquid system, the mortar will have very good flow properties.
Perlite insulation board: This product can be used in the refractory industry to produce 0.6g/cm3 lightweight energy-saving refractory bricks, and various ultra-lightweight energy-saving refractories, which can replace 50% floating beads, and is a new replacement product for floating beads. Not only can improve product quality, but also reduce production costs. Due to the high price of floating beads, the closed-cell surface melted hard-shell vacuum-ball expanded perlite is less than 2/3 of the price of floating beads, and the performance is better than that of floating beads. All refractory plants gradually began to apply a large number of closed-cell surface melting hard shell vacuum. Spherical expanded perlite, and China's production of closed-cell surface melting hard shell vacuum spherical expanded perlite began to take off, the production volume is only two-tenths of the demand, the market prospect is broad, and the demand is large.

An aldehyde is an organic compound containing a functional group with the structure −CHO, consisting of a carbonyl center (a carbon double-bonded to oxygen) with the carbon atom also bonded to hydrogen and to an R group which is any generic alkyl or side chain. The group-without R-is the aldehyde group, also known as the formyl group. Aldehydes are common in organic chemistry. Our main aldehyde products are Formaldehyde and paraformaldehyde.
