The first domestically developed and manufactured water vapor sealing durability test chamber

1. Overview
The insulating glass high and low temperature alternating test chamber is the latest water and air sealing durability equipment for insulating glass developed by our company. The test chamber is suitable for moisture resistance and heat resistance tests of laminated glass. It adopts intelligent instruments to automatically Multiple automatic control functions for controlling and detecting results. The overall design has many advantages such as easy operation, stable performance, high control precision, and accurate collection.
2. Equipment Principle
According to/standards, imported high-efficiency refrigeration compressors, stainless steel heating tubes, and electric heating humidifiers are used And other accessories, using touch screen intelligent instrument control, automatically complete the two stages of the standard. The whole process consists of two parts
Hourly temperature cycle, a total cycle (week)
Hourly (weekly) constant temperature stage, requiring relative humidity
3. Technical Parameters
Standards Calculate the inner volume in cubic meters. Dimensions of the inner box (depth, width and height). Dimensions of the outer box (depth, width and height). Door opening size (width and height). Single door. Ambient temperature is ~℃, relative humidity. Sample capacity. Glass sample size. Temperature range above sample piece glass interval. ℃ ~ + ℃ temperature fluctuation degree ℃ temperature rise and fall rate ℃ / (no load) humidity range ~ relative humidity deviation
4. Meet the standards
/ Check low temperature test method / Check high temperature test method / Check constant humidity and heat test /Check the technical conditions of the low-temperature test chamber for the alternating damp and heat test. The technical conditions of the damp and heat test chamber. /Durability temperature test, accelerated durability test "Test methods and requirements for long-term water vapor penetration"
5. The sample procedure is as follows
The whole process consists of two parts: a temperature cycle, a constant temperature stage of one cycle (week)) hours (weeks), which requires relative humidity and allows condensation on the surface of the sample. Specific Requirements for the Temperature Cycling Phase Humidity requirements during the temperature cycle, maximum humidity levels, and no humidity control required during the low temperature phase of the cycle. Condensation on the specimen surface is allowed. Time interval,,,, (one cycle time) During the cycle, high temperature stage ℃, low temperature stage ℃, temperature change ℃/constant temperature stage ℃
