【摘要】：对于市场前景广阔的气相二氧化硅和玻璃纤维芯材的真空绝热板(Vacuum insulation panel,VIP),可以通过检测其内压值来检测VIP质量。本文以负压膨胀法(即逆真空法)原理研发了内压测试仪,可以快速有效地测试VIP板内压强值,以此判别该VIP板是否合格。对测试结果与理论值进行对比发现,该测试仪精确度较高,误差可以控制在1%左右。然后,研究了不同口径大小吸盘对玻璃纤维芯材VIP内压测试结果的影响,试验证明仅小口径吸盘才能成功地测试该类VIP板内压值。最后,采用MATLAB线性拟合模块研究了两种VIP板内部压强与导热系数的关系式,可以从理论上更好地指导VIP板的高质量生产。
[Abstract]:The vacuum insulation panel for the market prospect of fumed silica and glass fiber core material (Vacuum insulation panel, VIP), can be detected by their internal pressure value to detect the quality of VIP. Based on the negative pressure expansion method (inverse vacuum method) principle developed internal pressure tester, which can quickly and effectively test pressure VIP plate this value in identification of the VIP board is qualified. The test results were compared with the theoretical value, the instrument has high accuracy, the error can be controlled at about 1%. Then the effects of various sizes of sucker on glass fiber core material VIP internal pressure test results, the test proves only a small diameter sucker can be successfully the VIP test value of pressure plate. Finally, study the relationship of two kinds of VIP plate internal pressure and the thermal conductivity of the MATLAB linear fitting module, high quality production can theoretically guide better the VIP board.
