Ceramic fiber Products

Products introduction：

Ceramic fiber is filtered vacuum pressure forming, using blowing fiber (fiber is short, thin, easily broken mix) as ceramic fiber materials, adding a certain percentage of the inorganic binder material. After beater dispersed into slurry. Then pumped into the molding pool, and stirred with compressed air, into the mold forming pools, using the principle of vacuum pumping, and mold pressure, molding and stripping, stripping thick ceramic fiber, due tothe presence of water, to be placed tray drying oven dried 10-24 hours away. After drying fiberboard through dedicated grinding machines, trimming machines, precise control of dimension.

Ceramic fiber Features：

1, hard and excellent strength, anti-erosion, easy processes cutting.

2, light weight, good insulation effect, is a versatile product that can be applied to the lining of flame and heat resistant surface air temperature direct impact.

3, product variety, depending on temperature (800 ℃ -1800 ℃), corrosion resistance, easy processing cutting, direct contact with the flame, easy to install.

4, the product has good resistance to thermal shock performance, versatile features.

Gravity castable refractory and its advantages

For refractory castable, lightweight refractory castable may we all already know, we know that is a castable refractory material joined by a certain amount of granular and powdered materials made ​​binders.So gravity refractory castable, we know how much of it, below by Yilong Refractories Co. professionals to introduce what is gravity casting material, and what are the advantages and other issues

Gravity casting material is a no vibration to flow and degassing castable  refractories. Its characteristics are not reduced or are not significantly reduce the performance of castable under conditions appropriate to add water; no vibration can be cast into a variety of shapes of construction thereof. Gravity casting material for thin-walled or complex shapes can not use vibration molding casting parts.

Gravity castable and vibration castable compared with the following advantages:

1. Lightweight refractory castable can flow under its own weight without vibration.
2. Lightweight refractory castable can automatically spread out and reach vibration castable unable to reach the site.
3. Pumpable lightweight castable refractory construction, reduce labor intensity, speed up the construction cycle.
4. Lightweight refractory castable reduce construction noise pollution.

The application of ceramic fiber refractory material

Application of ceramic fiber refractory material widely, now to introduce its is mainly used to:

1. The door of various insulation industrial kiln mouth seal, curtain.
2. The high temperature flue, wind tube bushing, expansion joint.
3. Petrochemical equipment, containers, pipelines and heat insulation, thermal insulation.
4. Under the environment of high temperature protective clothing, gloves, helmet, helmet, boots.
5. Automobile engine porcelain heat shield, heavy oil engine exhaust pipe package, Speed Racer composite friction brake pad.
6. High temperature liquid transfer pump, compressor, gas and valve packing, gasket.
7. High temperature electrical insulation.
8. Fire doors, fire curtain, refractory blanket, then spark with cushions and insulation cover fire sewing products.
9. Aerospace, aviation industry with insulation, insulation materials, friction brake pad.
10. Cryogenic equipment, containers, pipelines, heat insulation package.
11. The high-grade office archives, vault, safes and other important places of adiabatic, fire compartment, fire automatic shutter

The definition of the fire resistance of refractory material

Refractoriness refractory contend in no load temperature when the utility without melting softening function. Significance and melting refractory degree is not the same. The melting point is a crystallization of pure object phase and liquid phase in the flat static temperature. While the ordinary refractory material is composed of a variety of mineral synthesis of multi solid mixture, non congruent melting, but under certain temperatures have liquid, liquid on the proportion unceasingly increases with the temperature rising, to a fixed temperature solid phase can completely melted into a liquid, in a temperature range the two fixed temperatures during the in both liquid and solid, two also exist.

The fundamental decision conditions refractoriness of the material chemical mineral synthesis and distribution. Variety magazine, especially magazine ingredients with strong flux utility, will seriously decrease products refractoriness. Component is not evenly distributed, high melting point of mineral and cannot constitute an ideal, will make the products refractoriness decreased. Note the, refractoriness does not represent the product using the temperature, because the refractory material in the process often subjected to high temperatures utility at the same time, also with load and material flux effect, so the temperature often are much lower than the refractoriness.

Refractoriness are usually made of cone, pyrometric cone scale representation. Measure refractory refractory experimental approach is: will the tested refractory raw materials or made of refractory fiber products test cone with known refractoriness scale cases in cone, in under the premise of gun and compare test cone and scale of smelting temperature cone bend down, until the test cone top bent the pilot scale contact chassis, and on behalf of the cone bend down the temperature for the test cone refractoriness.
