Centrifugal glasswool for steel structure
Glass wool felt is mainly used for industrial purposes such as steel structures, thermal pipelines, and LNG liquefied gas storage tanks. Glass wool felt is an elastic felt made by using centrifugal technology to fiber molten glass and adding thermosetting resin based glass fibers. Different moisture-proof and fireproof series veneers can be selected according to usage requirements for online composite. It has a large number of tiny air voids and performs well in insulation, sound absorption and noise reduction, control of condensation and condensation, and safety protection. It is an ideal material for insulation in steel structure buildings. : 4008215192
| Introduction
Wahlee Industrial Glass Wool Felt has a uniform distribution of slender glass fibers, strong resilience, low thermal conductivity, and superior insulation performance. According to the test results, for every 1HT (about 1/4 micrometer) decrease in the diameter of glass fiber in commonly used industrial glass wool products, the thermal conductivity value can be reduced by 2.3%. The diameter of Wahlee glass wool felt glass fiber is usually about 5 micrometers, making it a high-quality insulation material.
| Performance
The selection of product specifications is usually determined by two factors:
1. The requirement for maintaining the thermal resistance value (R value) of the structure is determined by the climate conditions of the building location: R=T/K (T - thickness of glass wool felt, K - thermal conductivity of glass wool felt), so that the required specifications of glass wool felt can be calculated< Br> 2. Requirements for controlling condensation and condensation in the working environment of buildings: In addition to being related to the temperature of the working environment, condensation and condensation are also related to the relative humidity of the indoor air. To control condensation and condensation, it is required to use thermal calculations and responsive glass wool felt to make the surface temperature inside the building higher than the dew point temperature.
