Summary: The insulating glass high and low temperature alternating test box is the latest development of insulating glass moisture seal durability equipment, the test box is suitable for laminated glass moisture resistance test and heat resistance test, The automatic control of intelligent instrument and the automatic control function of test result are adopted. The whole design has many advantages, such as simple operation, stable performance, high control precision, accurate collection and so on. Principle of equipment: According to the GB/T11944-2012 standard, the imported high-efficiency refrigeration compressor, stainless steel heating pipe, electric heating humidifier and other accessories are adopted, and the intelligent instrument with touch screen is used to control the two stages of the standard 7.5.2. The whole process consists of two parts: 1. 12 hours of temperature cycle, a total of 56 cycles 4 weeks; 2. The constant temperature stage of 1176 ±4 hours / 7 weeks requires a relative humidity of ≥ 95. Technical parameters: Nominal internal volume: 1 cubic meter inside box size: W 700mm × D800mm × H900mm (deep X width X high); outer box size: W 1260mm × D1320mm × H 1920mm (deep X width X height; door size: 1000 × 1000 (width × high mm); single door temperature 535 ℃, Relative humidity ≤ 85%RH sample capacity: glass sample size 510mmX360mmX24mm sample ≥ 20 pieces of glass spacer temperature range: -20 ℃ ~ 80 ℃ temperature fluctuation: ±0.5 ℃ rising and cooling rate: 0. 7 ~ 0. 7 ℃ / min (no load) humidity range: 45? 95 RH relative humidity deviation: ±5.0%RH Criteria met: GB/T2423.1-2001 test A: low temperature test method GB/T2423.2-2001 test B: high temperature test method GB/T2423.3-2001 test Ca: constant hygrothermal test GB/T2423.4-2001 test Cb: alternating hygrothermal test GB10589-89 low temperature test box Technical condition GB10586-89 hygroheat test box technical condition GB/T11944-2012 durability Accelerated durability Test for temperature Test GB18045 (EN1279-2: 2002E) "Test methods and requirements for Long-term Water Vapor Penetration" The sample procedure is as follows: The whole process consists of two parts: 1. 12 hours of temperature cycle, a total of 56 cycles 4 weeks of 2. In the constant temperature stage of 1176 ±4 hours / 7 weeks, the relative humidity is ≥ 95 and the surface of the specimen is allowed to be exposed. The specific requirements of the temperature cycle phase: the humidity requirement during the temperature cycle, the maximum humidity ≥ 95, in the low temperature cycle, the humidity control is not required. Allow the surface of the specimen to be exposed. In the 12 h cycle, the high temperature stage is 53 ±1 ℃, the low temperature stage is 20% -18 ±2 ℃, the temperature change is 10% 14 ±2 ℃ / h, the constant temperature stage is 58 ±1 ℃.
Summary: The insulating glass high and low temperature alternating test box is the latest development of insulating glass moisture seal durability equipment, the test box is suitable for laminated glass moisture resistance test and heat resistance test, The automatic control of intelligent instrument and the automatic control function of test result are adopted. The whole design has many advantages, such as simple operation, stable performance, high control precision, accurate collection and so on.
