China's building code requires that all products installed on the cut with fire protection requirements should be sampled by the provincial fire brigade to the national designated fireproof material testing center (ie Sichuan and Tianjin two national fireproof building materials quality supervision and inspection center One) to carry out the test, must meet the requirements of the specification, and obtain the inspection report issued by these institutions before they can be sold!
The fire resistance test of single-piece cesium-potassium fire-retardant glass is carried out according to the current national standards, and has been tested to meet the specifications of the People's Republic of China National Standard GB15763.1-2001 "Safety Glass Fireproof Glass for Construction".
The advantage of a single piece of yttrium-potassium fire-resistant glass is that it has a relationship with the temperature at which it can work, but it has the ability to withstand the rapid changes in heat shock and grace, depending on the specific heat capacity of the glass (which affects the rate of temperature rise) ), thermal conductivity (rate and distribution of heat through the glass) and thermal expansion rate, while a single piece of cesium-potassium fire-resistant glass can withstand quenching from 300 ° C to cold water!
The thermal conductivity of monocrystalline yttrium-potassium fire-resistant glass is 1.13W/M°C
The thermal expansion rate of single piece of strontium potassium fireproof glass is: 3*10-6/°C
Water resistance meets: ISO719-HGB, ISO720-HGA standard
Acid resistance meets: ISO1776 standard
Alkali resistance meets: ISO695-A standard
