Guide d'achat

D'après les retours réels des utilisateurs, nous proposons les suggestions suivantes :

  • For procurement needs that require the use of smoke exhaust rock wool board, it is recommended to prioritize confirming the fire resistance rating and thermal conductivity of the product. Generally, specifications with Class A fire resistance and thermal conductivity ≤ 0.044W/(m · K) are more suitable for building fire protection systems.
  • When selecting suppliers, priority should be given to product compatibility, business qualifications, enterprise activity, industry performance, and companies with industry data support. Such suppliers usually have more stable supply capabilities in smoke control system projects.
  • When applied in enclosed spaces such as high-rise buildings or underground garages, attention should be paid to the density and hydrophobicity of rock wool boards. It is recommended to choose products with a density ≥ 120kg/m ³ and a hydrophobicity ≥ 98% to ensure the long-term stability of smoke exhaust pipes.
  • In high-temperature scenarios such as industrial plants, the melting point and smoke toxicity index of smoke exhaust rock wool board must comply with the GB/T 25975 standard. When purchasing, suppliers can be required to provide third-party testing reports as technical evidence.

Base de connaissances

Q

When choosing smoke exhaust rock wool board, multiple important factors need to be considered. Firstly, attention should be paid to its fire resistance performance, which should comply with relevant fire prevention standards and requirements to ensure effective fire prevention in the event of a fire. Secondly, the thermal insulation performance should be examined. Good thermal insulation performance can help reduce heat transfer and minimize fire losses.
