How much is the phenolic insulation board, and the advantages of phenolic insulation board compared

Phenolic insulation board is divided into B1 grade and composite A grade.

A-grade phenolic composite board is about 2200 yuan cubic meter.

B1 grade phenolic board is around 1800.

This is divided into product types, now there are two kinds on the market, one is molded, one is the assembly line, the quality of the assembly line is better, ** will be more expensive, depending on how much bulk density you want, Jilin Xuelong Taida phenolic board factory production line, ** is about 1,000.

Phenolic insulation board is made of thermosetting phenolic resin foaming, which has excellent fire resistance, heat insulation, sound insulation, light weight and energy saving properties, heat resistance, flame retardant self-extinguishing, flame penetration resistance, no dripping in case of fire and flame retardancy to prevent the spread of flames.

This mainly depends on the density and specifications of the product, the 40 kg of mold foaming is about 400 yuan, and the ** of the assembly line is slightly more expensive. Specifically**You can consult: Langfang Shunying insulation.

The first place is different, and it is also divided into bulk weight, Jilin Xuelong Taida Phenolic Board Factory produces assembly line plates, and the 50kg bulk density is about 1200.

The continuous line is about 1400, and the mold is about 650, so it is necessary to consult Xinxiang Hongfu anti-corrosion and thermal insulation 0373-2681348

Phenolic insulation board** is determined by density, process and board thickness, depending on what specification you use.

The phenolic fireproof insulation board is affected by many factors. For example, density, production process, fire rating, etc., I don't know which one you are talking about? About phenolic fireproof insulation board**Here are detailed instructions, you can find out for yourself first.

Phenolic insulation board is made of phenolic foam, phenolic foam is a new type of non-combustible, fireproof and low-smoke insulation material, which is a closed-cell rigid foam made of phenolic resin with foaming agent, curing agent and other additives.

Phenolic insulation board is made of phenolic foam, phenolic foam is a new type of non-combustible, fireproof and low-smoke insulation material, which is a closed-cell rigid foam made of phenolic resin with foaming agent, curing agent and other additives. Its most prominent features are non-combustible, low smoke, and resistance to high temperature discrepancy. It overcomes the shortcomings of the original foam plastic insulation material that is flammable, smokey, and deformed when heated, and retains the characteristics of the original foam plastic insulation material such as light weight and convenient construction.

Advantages of phenolic insulation board over other insulation materials:

1. The difference between phenolic insulation board and polyurethane insulation material.

Phenolic fiber insulation board is non-flammable and non-toxic, but although polyurethane has good thermal insulation performance, it is flammable and produces toxic gases.

2. The difference between phenolic insulation board and rock wool and glass wool.

Rock wool and glass wool pollute the environment, and it is easy to breed bacteria, the water absorption rate is also high, and the use time is short, but the phenolic insulation board is different, the phenolic insulation board is made of environmentally friendly materials, and it will not breed bacteria, and the life span is up to 30 years without deformation, and the thermal insulation performance is good.

3. Compare the difference between polystyrene foam.

The defects of polystyrene are that it is easy to burn when exposed to fire, shrink after a long time, and have poor thermal insulation performance. The phenolic insulation board has a uniform closed-cell structure, low thermal conductivity, good thermal insulation performance, comparable to polyurethane, and better than polystyrene foam.

1. Start from the supporting part from bottom to top, use polymer sticking mortar to paste the phenolic insulation board on the wall. The bonding area should be greater than 35%, and the first layer should be greater than 50%. If the outer sheath is heavier, 4-6 insulation nails should be nailed per square meter.

2. After bonding, it should be stopped for 24 hours before the protective layer construction. 3. The construction of the external application surface can be carried out every 24 hours. 4. The thickness and density of the insulation board should not be less than 4cm in the north of the Yellow River according to the design requirements, and the density should be 50kg m, and the cold area should be thickened.

What are the characteristics of phenolic insulation board? Phenolic resin insulation board is made of phenolic foam resin, phenolic foam resin is a new type of non-combustible, fireproof and low-smoke insulation material, which is a closed-cell rigid foam made of phenolic resin with foaming agent, curing agent and other additives. Its most prominent features are non-combustible, low smoke, and resistance to high temperature discrepancy.

It overcomes the shortcomings of the original foam plastic insulation material that is flammable, smokey and deformed when heated, and retains the characteristics of the original foam plastic insulation material such as light weight and convenient construction.

Phenolic foam resin insulation board has good thermal insulation performance, and its thermal conductivity is about, which is far lower than the inorganic and organic exterior wall insulation products commonly used in the market, and can achieve higher energy-saving effects.

The use of excellent fire performance insulation layer phenolic foam, and other materials for building insulation, can basically reach the national fire standard A, fundamentally eliminate the possibility of external insulation fire, the use of temperature range of -250 +150.

How to identify the quality of phenolic insulation board].

1.The production is produced by large foam, and the product produced by this method is relatively low in density, easy to be brittle, and easy to appear pulverized or slag.

2.The other is the assembly line production, which is to make a warm plate for modified phenolic protection, which is to improve its phenolic resin and foaming process, and produce a modified phenolic insulation board to overcome the shortcomings of its own pulverized slag to a certain extent, so that the density of the modified phenolic insulation board is generally more than 55kg. 3.

In addition to the above methods of identification, we can also observe the appearance of the phenolic insulation board, press the density by hand, break it to see the toughness of the insulation board, and rub it by hand to determine the quality of the exterior wall phenolic insulation board.

4.In addition, when buying insulation boards, you must choose regular manufacturers to buy, because such regular manufacturers, the products they produce are controlled by strict quality supervision departments. The quality problems of the products produced by such regular manufacturers are relatively rare.

Phenolic insulation board meets the standard and is welcomed by the market

It is understood that phenolic foam board is made of phenolic foam board made of phenol and formaldehyde condensation polymers mixed with other additives, and Japan's building insulation system has been made of phenolic foam board packaging machine.

Fortunately, the composite phenolic foam board developed by most domestic enterprises has been tested by the National Center for Quality Supervision and Inspection of Fireproof Building Materials, and its combustion performance has reached GB8624A. This shows that as a safe, green new energy-saving building material, the advantages of phenolic foam board have been recognized by the construction department and the public security and fire department.

In 2009, the Ministry of Public Security and the Ministry of Housing and Urban-Rural Development jointly formulated the Interim Regulations on Fire Prevention of External Thermal Insulation Systems and Exterior Wall Decorations of Civil Buildings, which requires that "the combustion performance of external thermal insulation materials in civil buildings should be Class A and should not be lower than Class B2"; In 2011, the Fire Bureau of the Ministry of Public Security issued a "Notice on Further Clarifying the Relevant Requirements for the Fire Supervision and Management of External Thermal Insulation Materials in Civil Buildings", requiring that "the standard for the use of external wall insulation materials in civil buildings shall not be lower than Class A", in order to cut off the soil for fire breeding from the root.
