high quality calcium silicate pannel

Specifications

1000C calcium silicate insulation board

 The main constituents of YONGDA-1000C calcium silicate insulation board is xonotlite and reinforced glass fibre, no asbestos. It is a kind of high efficient energy-saving material with temperature limited 1050 cent-degree. Characterized by low bulk density, high specific strength, superior heat resistance, outstanding thermal insulation, excellent durability, chemical corrosion resistance, easy to be cut by say and easy installation, calcium silicate can be widely used for the insulation of industrial kiln.

Physical and chemical microstructure production, technology

The main constituent sonotlite is synthesized through dynamic hydrothermal process using quartz and lime as raw material. The microstructure crystal looks like a hollow cactus ball and make the board has superior features, unique and irreplaceable

♦ Low thermal conductivity figures---provides top insulation throughout its temperature range.

♦Good thermal stability—withstand continuous heat up to its full temperature use limit with small liner    shrinkage.

♦ Light bulk density—low heat storage

♦ High mechanical strength—specific strength superior other shaped insulations and retains full integrity at        elevated temperatures(excellent creep --resistance)

♦ Long service life—no pulverization such like ceramic fiber felt.

♦ Safe and clean operation—free from asbestos, suiphur, and chloride, no toxic carcinogen.

Application and installation

Calcium silicate insulation board are used on all kinds of industrial branches to provide high quality insulation backing. In kiln system, the insulation board is not exposed to the fire, so the requirement to the insulation material is different from refractory material. Very high use temperature, very high thermal shock resistance and very high mechanical strength are the requirement to refractory material which touch the fire directly. But these item are not important to insulation material. The necessary technical properties for insulation material as following:

♦ Low thermal conductivity

♦ Low bulk density

♦ Gas resistance(CO, NH3, H2 and CH4)

♦ Easy cut and installation

Calcium silicate can meet all above requirement and replace other insulation material, it is becoming dominant on insulation of industrial kiln.

Areas of application:

♦ Cement industry: Preheaters and cyclone separators, decomposition kiln , tertiary air duct and cooler.

♦ Nonferrous metallurygical industry: Aluminum power calciner and electrolysis groove.

♦ Petrochemical industry: Splitting furnace, catalytic cracking furnace, petroleum pipeline, underground heat-flooding

♦ Metallrugican industry(steel plant): Hot-rolling heat furnace, cool-rolling miss set, RH vacuum degassing furnace,    smelters, hot deformation and heat treatment plants.

♦ Power plant: Preheat stove, pipe

♦ Glass industry: Melting furnace and recuperator, annealing furnace and cooling channels

♦ Ceramic industry: chamber and tunnel furnace

Accessories and installation

 Auxiliary products

YD-1 high temp adhesive: Blended with water glass to form a mortar for the tight connection between insulation board with board, also can be used for insulating board and other under drop with consumption about 3.0kg/m2.

YD-2 waterproof agent: when our insulating board is used with casting material and other monolithic refractoriness, waterproof agent is painted on the interface with consumption 3.0kg/m2

♦ Installation tool: Basin and trowel

♦ Clean the contact face firstly

♦ YD-1 one portion: water glass (also named sodium silicate) of about 1-1.5 portion: according to the circumstances surrounding the construction site to determine, thick moderately lean, these two material fully mixed evenly, you can use.

♦ Bonding between the calcium silicate board thickness 1.5-2mm, can be forced extrusion.

Because our board has very good process ability, the general architecture fixer can be used if need.

♦ Moisture absorption of calcium silicate board, if do not use water-proof agent, waxed paper and PE film should be considered to be used to separate with casting material.

♦ Binder is used the existing service, not to store too much time to avoid hardening crust, will can not be used.
