The main purpose of rock wool board in construction is that the rock wool composite board is now more and more widely used in construction. It is a good fireproof and heat insulation waterproof material, which plays an important role in the construction industry. The rock wool composite board construction industry is indispensable. a building material. The rock wool composite board is made of basalt and other natural ores, and the rock wool board is melted into fiber by high temperature, added with appropriate amount of binder, and solidified and processed. Rockwool board products are suitable for thermal insulation and sound insulation of industrial equipment, construction and ships.
Tarp eyelets, which also can be called as tarp grommets are placed on all the edges of tarpaulins, to allow ropes or strings to go through, and tie the tarpaulins closely with carriers, such as truck, car, bicycle, ground, etc. The eyelets various in material of aluminum, brass, plastic. Aluminum eyelets are most popular because of their rust-proofing and low cost. Brass eyelets are rare due to the high cost. Plastic eyelets, short as PC eyelets, or some calls as policarbonate eyelets, look fancy so somoe customers would like to buy though it is the most expensive.
The most common and popular eyelets are of inner diameter 1.3(+/-0.2)cm and outer 2.3(+/-0.2)cm. The dimension and material can also be made as per special request. Welcome to inquire any time!
It is suitable for pipeline insulation and heat insulation in electric power, petroleum, metallurgy and shipbuilding industries, especially for small-port straight pipeline construction. The waterproof rock wool tube has special functions of moisture proof, temperature discharge and drowning. It is especially suitable for use in rainy and humid environments. The moisture absorption rate is below 5% and the drowning rate is over 98%. Waterproof rock wool board adds waterproofing additive to the production, which makes the product have better moisture and water repellency. It is mainly used in ships, buildings and other places where there is certain requirement for moisture and fire prevention. The water-repellent rock wool board has a water-repellent rate of more than 98% and a moisture absorption rate of less than 5%. Marine rock wool insulation board and hydrophobic rock wool insulation board have added hydrophobic additives during production, which has good moisture resistance. Marine rock wool board is used for ship thermal insulation and fireproof partition; hydrophobic rock wool board is used for vehicles, mobile equipment, cold storage engineering, air conditioning ducts, and thermal insulation in humid environments and applications where moisture is required. The rock wool board for construction has excellent fireproof, thermal insulation and sound absorbing properties. It is mainly used for thermal insulation of building walls and roofs; fire protection and noise reduction of building partitions, firewalls, fire doors and elevator shafts. Specification (mm): 1000×630 thickness (mm): 30-100
Special specifications according to requirements, custom weight (kg): 60-150kg/m3
The stability and flame resistance of the important application areas of rock wool insulation boards have been put forward, and the rock wool insulation board has been developed more rapidly. As a new type of multi-purpose foam material, phenolic resin foam is heat-resistant, flame-retardant, self-extinguishing, flame-resistant,
It has received extensive attention due to the advantages of no dripping in the fire.
The rock wool insulation board is a phenolic resin as a main raw material, and a curing agent, a foaming agent and other auxiliary components are added, and the foaming agent generates a foam which is formed by foaming while the resin is cross-linked and solidified.
It has many excellent properties, first of all heat resistance - the final cured rock wool insulation board has a structure comprising several phenol rings and connected by a methylene bridge. It is known by thermodynamics that the methylene bridge is an organic connection.
One of the least stable and most stable connections, which makes rock wool insulation boards excellent in thermal stability. It can be used at 150 °C for a long time, and the instantaneous working temperature can reach above 200-300. Its high temperature resistance is obviously better than other foams. "Flame fire" is also outstanding. Phenol molecules are good free radical absorbers. During the pyrolysis process, the free radicals produced by the cleavage of the methylene bridge are rapidly absorbed by the phenol molecules, preventing the reaction from proceeding. This phenomenon makes the rock wool insulation board extremely difficult to burn; The rock wool insulation board has an oxygen index of 50, no need to add any flame retardant additive, and the flame retardant grade is flame retardant B1 grade. The high-density rock wool insulation board with inorganic fillers has an oxygen index of 70, and the combustion performance meets the requirements of the German DIN4102 building materials class non-combustible A2. Resistance to flame penetration. According to experts, the rock wool insulation board has carbon deposits, no dripping, no curling, no melting under the direct action of the flame. After the flame is burned, the foam is basically retained, but the surface forms a layer of “graphite foamâ€, which is effective. The layer protects the foam structure within the layer.
