Application of phenolic foam in thermal insulation in developed countries

In industrialized countries such as Britain and Japan, there are strict fire protection requirements for wall insulation of important buildings and high-rise buildings. In recent years, the relevant construction departments of various countries have turned their attention to energy-saving and fire-proof PF for wall insulation systems.

British Pumalock Products Co., Ltd. is a well-known manufacturer of phenolic thermal insulation boards. The phenolic foam (PF) fire performance reaches the first level of British Standard BS476-7. After years of research and development, the company has developed and implemented a complete and mature application technology system specification in accordance with British standards, and successfully applied to masonry or concrete walls, regardless of new or existing, high-rise Or low-rise buildings can be applied. After testing and evaluation, the relevant construction department awarded the company the “phenolic external insulation system” application license (certificate No. 041/97). The company claims that the insulation system will not be damaged for at least 30 years after construction of public buildings or residential buildings.

British Knauf Drywall Company. Knauf Drywall is part of the German Knauf Group, the largest and the first family to produce gypsum board. Its product name is Knauf Phenolic Resin Composite Board, which is a 9.5mm gypsum board veneer PF wall insulation board. The main sales object is used for exterior wall insulation and partition wall. The biggest feature of the product is its excellent fire, heat insulation and sound insulation properties. In particular, the sound insulation performance is especially important for noise reduction in housing and office buildings.

American Xibi Chemical Company. Founded in 1966, Xibi Chemical Co., Ltd. has been engaged in the production, sales and research and development of phenolic resins, surfactants, catalysts and related foaming equipment for many years. For nearly 40 years, the company has been developing a PF called Tripolymer, which was supported and endorsed by the US Department of Energy in 1975. After three years of intensive research and experimentation, it has successfully brought it to market. Today, the company has eight manufacturing facilities in the United States and has established facilities in the UK, Germany and Australia.

In recent years, the company has developed a patented technology that directly injects foaming slurry into a hollow brick or hollow cement block through a spray gun. The foaming slurry is a two-group of modified phenolic resin copolymer and curing agent. Dipolymer prepolymer. Due to its excellent fire resistance and sound insulation, Tripolymer has been widely used in schools, hospitals and residential buildings. Through the US "Combustion Level Test Standards" standard, there is no other organic foam that can be injected on site to achieve the excellent fire performance of Tripolymer.

1. Product introduction

   Magnetic Water Purifier Granular Activated Carbon is the appropriative Activated Carbon for aquarium to remove fish odor Filter Material . Its unique dense porous structure has good effect to decompose fish feces and food residue, remove smell, heavy metal pollutants and chlorine, decolorization, balance pH value; high dynamic adsorption rate, which can quickly remove various pollutants in water, rapidly increase the water clarity; it can make the fish surface microglia produce protective film, especially has great function for control and repair ornamental fish rotten, unfinished and rotten mouth.  

2. Application

a. Magnetic water purifier Granular Activated Carbon has a strong adsorption for bacteria and decomposition of fecal capacity, most suitable for the multi dung tanks.

b. Magnetic water purifier granular activated carbon is suitable for seedling cultivation in the seawater, seawater purification, and also effectively remove pollutants in seawater, restore water quality, improve the survival rate of seedlings.

3. Process  

  Coal-based granular activated carbon with high quality Anthracite as raw material, it produced by high temperature steam, and by carbonization, activation, crushing and sieving process.

4. Transportation and packaging

a. Woven bag, lined with plastic film bags, each 25kg, also be packaged according to customer demand; activated carbon in the transportation, to prevent mixed with hard materials, do not step,to prevent carbon particles broken, affecting the quality.

b. Storage: the product should be placed in a cool and dry place;in the transportation and use, to prevent water immersion;

c. To prevent tar substances: in the process of use, tar substances should be prohibited into the activated carbon bed that to plug the activated carbon gap, loses adsorption;

d. Fire prevention: activated carbon in storage or transportation, to prevent direct contact with fire, in case of fire; activated carbon after regeneration should avoid oxygen, the after regeneration`s activated carbon should be steam cooling to below 80 DEG C, or high temperature, with oxygen, activated carbon combustion.
