2.Excellent flexibility
3.Low heat capacity

Item name:  Standard Ceramic Fiber Folding Block

Ceramic fiber blocks for thermal insulation

All kinds of ceramic fiber folded block, using the corresponding materials are ceramic fiber blanket acupuncture, according to fiber components of the structure, size and mechanical processing on the dedicated form.  

In the course of processed, are to maintain a certain proportion of compression to ensure the ceramic fiber lining folded block wall construction has been completed, because each piece of folded pieces of ceramic fiber in different directions on the expansion,

so that pieces of ceramic fiber folded between the extrusion into a seamless whole.

Product Characteristics

1.Excellent chemical stability;

2.Excellent thermal stability;

3.Excellent flexibility, because of fiber in a pre-compression state, and its expansion can be compensated fiber contraction, improve the insulation properties of fiber lining;

4.Low heat conductivity;

5.Low heat capacity.

Q:Is there vermiculite in refractory?
In refractory field, vermiculite is usually used as fireproof thermal insulation material.
Q:What are the qualifications of refractory industry?
Special qualification issued by Fire department
Q:What's the heat conductivity coefficient of fire-resistant material?
The heat conductivity coefficient of fire resistant material is related to bulk density and mainly related to the internal structure. Different materials have different structure and thermal conductivity and temperature . Carbonaceous material can be used for heat dissipation and reach more than 15. For thermal insulation it can be 0.00.
Q:Where is the development of refractory industry?
Refractories for continuous casting is an important part of the continuous casting machine, in addition to the characteristics of general refractory material, also for the purification of molten steel and improve the steel quality, stable molten steel temperature and composition, control and regulate the flow of the molten steel and other functions, so it is called functional refractories.
Q:What are the commonly used fire protection materials
Firewall. The fire wall is made of non combustible material, and is directly installed on the base of the building or the reinforced concrete frame or fire proof walls . Fireproof limit of the firewall, according to the current "building regulations", is 4 hours, wheras the specification of Technical specification for concrete structures of tall building is 3 hours. doors resistant to fire, heat in a certain period of time These door usually prevent the spread of fire and gas in the fire resistant wall, staircase, pipe well. Fire door can be divided into steel fire doors, wood fire doors and composite materials fire door according to the material used. According to the limit of fire resistance can be divided into the class A fire door (1.2h), B fire doors (0.9), class C fire door (0.6h); (3) fire window. Windows resistant to fire, heat in a certain period of time It is usually installed in the fire resistance wall or doors; the fire shutter. This roller shutter can be refractory in a certain period of time. It is typically used for heat and fire insulation in escalator with difficulties to install fire resistant wall, fire resistant valve and smoke resistant valve. Fire resistant valve is installed in the ventilation and air conditioning system of air supply and return air duct, usually in the open state, fire, It will be turn off when the pipeline gas temperature reached 70 degrees, can meet the requirement for fire resistance and insulation for gas and fire. Smoke fire resistant damper installed in the exhaust system pipe, when the pipeline gas temperature reached 280 degrees, it will close automatically, insulating fire and gas.
Q:What is required to do refractory material?
I have no idea
Q:Who knows what fire heat preservation material are there?
1 thermal insulation materials with class A combustion performance Rock wool, glass wool, foam glass, ceramic foam, foamed cement, perlite and other 2. thermal insulation materials with B1 combustion performance Specially processed extruded polystyrene board (XPS) / specially processed polyurethane (PU), phenol, powder polystyrene particles. Heat-insulating material with B2 termal insulation performance Fire resistance can be thoroughly sloved by combining molded expanded polystyrene (EPS), extruded polystyrene (XPS) and polyurethane (PU), polyethylene (PE) Hairong module with glass beads (and cooperating with vitrified micro bead inventor Liu Weihua), hope my answer will help!
Q:How to deiron refractory?
Deironing refractory can take physical methods into consideration, such as magnetic separation, reselection, etc. And it can also take chemical methods, such as flotation.
Q:What's the maximum temperature that the refractory ceramic fiber cloth can endure?
It depends on the composition of the ceramic material. If its composition is alumina and it is used by civilians, its normal use temperature is 1200℃; if its composition is alumina but it is for millitary use, it can endure the highest temperature of 2200℃.
Q:Do you know where I can buy refractories?
A Address of Guangzhou Lingnan Refractories Co., Ltd. : No.1069 Guanghua 1st Road B Address of Guangzhou Aolian Refractories Co., Ltd. :
