Product introduction : Angao rock wool board is based on natural rocks such as basalt, green rock, dolomite, bauxite and other as the main raw materials, with a variety of inorganic additives, melted by high temperature, in the state of raw material melting, by high-speed centrifugal equipment centrifugal, due to the use of the central spray method, so fully ensure the uniform distribution of glue, so that wool and glue to achieve a combination. We use a special eco-friendly mineral adhesive that glues the rock wool fibers together to become a spray cotton. Spray cotton by swinging folding cloth cotton, cotton layer thick and uniform and achieved multi-layer vertical overlap structure, after the differential speed roller folding so that fiber folding cross-bound pressed together, so that Angrock cotton does not appear small production line products cotton layering phenomenon. After the pleated cotton directly into the curing furnace, by high temperature compression molding, and then cut off or cut by the process, and then into the automatic packaging line, packaging into the warehouse.All processes Process automated flow ingestion without human intervention.

Product advantage : 1.Thermal insulation performance is good: Angao rock wool insulation plate slag ball content is low, wool silk slender and flexible, so the thermal conductivity is low, with good insulation effect.

2.Fire performance stick: Angao rock wool because of its use of natural rock as raw materials, is a Grade A non-combustible building insulation materials, high temperature resistance.

3.Sound absorption noise reduction performance is good.

4.Corrosion resistance: Angao rock wool insulation plate invasion liquid PH value is neutral or weak alkaline, carbon steel, aluminum alloy, copper, stainless steel, cast iron and other metal equipment and building components are non-corrosive.

5.Health and environmental protection: Angao rock wool insulation board does not contain asbestos, the production process does not use CFC or HCFC and other harmful substances to the environment, does not have microbial growth environment, do not breed mold.

6.Anti-moisture: Angao rock wool insulation plate in the temperature of 50 degrees C, relative humidity 95% of the environment exposed for 96 hours, volume absorption rate of 0.2%, according to the national standard test, the quality moisture absorption rate is less than 1%.

Application : Angao rock wool is widely used in ships, metallurgy, electricity, construction and other industries, with good insulation, sound insulation, fire protection effect. Construction and installation convenience, energy-saving effect is significant, with a high performance price ratio. Rock wool slab is a new type of insulation, fire proof, sound absorption material. Marine and water-repellent rock cotton insulation plate in the production of water repellent additives, with good moisture-proof performance. Marine rock wool slabs are used for insulation and fire insulation of ships, and water-repellent rock cotton slabs are used in vehicles, mobile devices, cold storage works, air-conditioning pipes, as well as in wet environments for insulation and fire protection, as well as for applications where moisture protection is required. Construction rock wool slabs have excellent fire, insulation and sound absorption performance. It is mainly used for building walls, roof insulation, building walls, firewalls, fire doors and elevator shafts fire prevention and noise reduction.
