Brief introduction
Ceramic Fiber, also called aluminum silicate fiber, it is a kind of light weight refractory fiber. It possesses the performances and advantages of high temperature resistance, light, excellent thermal stability, low heat conductivity, small thermal capacitance and mechanical vibration resistance etc. The ceramic fiber needled blanket is the main products of ceramic fiber, it has higher tensile strength and other excellent features. As refractory material, it has found an increasingly wide utilization in the fields of in metallurgy, cement, glass industry, etc.
Production process
The complete ceramic fiber production line adopts electrical resistance furnace to melt the raw material (such as calcined kaolin clay, alumina, silica, zirconia, etc) into lava. Then the three-roller centrifuge will attenuate the molten fluid into fibers under the centrifugal force of the high speed rotational rollers to the lava. The crude blankets are formed in the collecting chamber and then carried out from the setting chamber. After going through the allocating conveyor, the crude blankets enter into the sintering furnace to be cured. Then the double-layer needling machine will needle the blanket to make the fiber layer tightly interweave with each other. Then after longitudinal and cross cutting, rolling, the crude blankets will become the needled blanket.
Equipment Introduction
Melting system
The electric resistance furnace could use the current generated between the electric resistances to melt the raw materials.
Fiber forming system
The fiber forming machine is three-roller centrifuge. The high temperature melting fluid will be dispersed and stretched into thin fibers by the centrifugal force of high speed roller.
Wool collector
The wool collector is used to collect the fibers into crude blanket. The fibers are evenly drawn on the mesh belt under the function of negative pressure air and become crude blanket.
Needling machine
Needling blanket is developed from the non-woven needling technique. The needle hooks move up and down and draw the fibers to make the fiber layer tightly interweave with each other. This process could improve the tensile strength and the wind erosion resistance performance of the blanket.
Sintering furnace
It could burn off the lubricant in the blanket and make fiber microcrystalline processing to achieve the heat shaping of the blanket and reach the required thickness and dimension.
Cutting and rolling system
This system is used to finish the cutting and rolling of the blankets. The blankets will be cut into pieces or strips and rolled into rolls according to the proceeding requirement.
Brief introduction
Rock wool is a kind of vitreous fiber that gets from slag, basalt, limestone and dolomite through fusion and fiber forming technique. It has good thermal and sound insulation property and widely used in building industry, chemical field, textile industry and many other fields.

Cooling conveyor
Its function is to make the product cool and convey the product to the next process.
Cutting system
It could proceed longitudinal and crossing cutting to make required products.
Packing machine
The packing machine is used to pack the rock wool board with one layer of shrinkage film, in order to facilitate the transportation and loading.
Glass wool is a kind of insulation materials which is made of natural ores, such as quartzite, dolomite, feldspar, limestone and so on. With the features of low density, fireproof, thermal insulation, the glass wool has found a wide utilization in the fields of petrochemical industry, architecture, etc.
The capacity of the glass wool production line is 2000-20000 tons per year. The raw material is cullet, feldspar, dolomite, calcined soda, borax, limestone, others. The fuel could natural gas or heavy oil, etc.
Production process
The glass wool production line is a complete set of machinery. The raw materials added with auxiliary agents such as calcined soda and borax are melted into glass fluid in the tank furnace. The lava is drawn, blown or thrown into very thin fibers under centrifugal force of the spinner. The forming fiber will be collected to be original blanket by wool collecting machine. The original felt is sent into the curing oven to be solidified and shaped by the conveyor. After curing, the products will go through the cooling section. It will be cut by slitting cutter and cross cutter according to the setting length. Finally, it will become the final products such as board, blanket.

Glass wool Insulation is one of the most widely used forms of insulations world-wide because of its thermal and acoustic properties, light weight, high tensile strength and exceptional resilience. Glass wool is one of the most dominant types of insulations preferred in applications with service temperatures ranging upto 250C.
Glass wool consist of fine, long, inorganic fibers bonded together by high temperature binder. These fibers (each of approx. 6 - 7 microns diameter) are distributed to trap millions of tiny pockets of air in it thereby creating it an excellent thermal and acoustic insulation. The light weight of Glass wool also offers significant advantages during transport and installation. In addition, Glass wool is chemically inert and has no impurities such as iron shots, sulphur and chloride. The product is non corrosive to metal and does not support mold grow. It is manufactured from renewable raw materials and is environmental friendly in every stage.
Glass wool is formed into products with various thickness and densities. It comes in the form of rolls and slabs with or without Aluminum foil Paper.

Most customers believe glass to be quite a fragile material. More and more customers are nonetheless coming to us, intending to decorate their staircases in such an edgy and virtually zephyrian style.
The point is that a glass stairway may look zephyrian and weightless, giving a feeling of suspension over the ground. But in reality glass stairs are quite strong, reliable and durable, just like a regular rock, and are capable of withstanding high loads. In our applications we use high-strength glass that has been subjected at least to thermal treatment or at most glued together into a safety glass (triplex).
We can fabricate any or all structural components of stairways and railings from glass: stairways, railings, stairs, hand rails, and bars. Moreover, you can order from Karvan-Glass the self-sustaining glass balcony parapets that will give you maximum observation field from your sunroom or balcony.
