不锈钢真空保温器皿保温性能检测管理数据

本管理数据通过专用设备“测温仪”采集本企业生产的各型号保温器皿的保温（保冷）温度数据，分析得到热（冷）损失速率和实际保温效能等相关产品数据信息，为企业生产优质保温器皿提供数据支持。 不锈钢真空保温器皿是用于存放冷热水、饮等液体（食品），由不锈钢加上真空层做成的盛水的容器，顶部有盖，密封严实，真空绝热层能使装在内部的水等液体延缓散热，以达到保温的目的。真空绝热（冷）技术广泛应用于航天领域，热（冷）力传播有三种途径：辐射、对流和传导。保温器皿内银色的胆能反射热（冷）水的辐射，胆和身的真空能阻断热（冷）力的传递，而不易传递热（冷）量的瓶塞能阻止热对流，从而达到保温的效果。本知识产权的数据是解决产品阻断热（冷）力的传递的信息数据。通过专用设备“测温仪”获取数据。热损失速率算法：产品敞口在规定环境温度20C±5℃下，放置30 min 以上，装人沸水(100℃)至密封盖(塞)下端在产品内水温实测温度达到95±1℃时，立即旋紧密封。在同样环境条件下，经过规定时间后，测定产品内水温。水温测量采用热电偶布置于热水中产生电信号，通过数据采集仪结合计算机软件将电信号转换呈现给用户温度数据。实际保温效能算法：热损失速率(J/s)=【水的比热容(4.2J/(g•℃))*容量(mL)*1g/mL*经过规定测量时间的温度差ΔT(℃)】/(测量时间(h)*3600s/h)。实际热损失速率(J/s)=【水的比热容(4.2J/(g•℃))*实测容量(mL)*1g/mL*经过规定测量时间的实测温度差ΔT(℃)】/(测量时间(h)*3600s/h)。This management dataset collects thermal (cold) retention temperature data of various types of thermal insulation vessels produced by the enterprise via a dedicated temperature measuring instrument, and analyzes product-related data such as heat (cold) loss rate and actual thermal insulation performance, providing data support for the enterprise to manufacture high-quality thermal insulation vessels. Stainless steel vacuum thermal insulation vessels are water-containing containers made of stainless steel with a vacuum layer, designed to store liquids (foods) such as cold/hot water and beverages. Equipped with a tightly sealed lid on top, the vacuum insulation layer can slow down the heat dissipation of internal liquids (e.g., water), thereby achieving the goal of thermal insulation. Vacuum insulation (cold retention) technology is widely used in the aerospace field. There are three primary modes of heat (cold) transfer: radiation, convection, and conduction. The silver-plated inner container of the thermal insulation vessel reflects the radiation emitted by hot (cold) water; the vacuum layer between the inner and outer shells blocks heat (cold) transfer; and the stopper with low thermal (cold) conductivity prevents thermal convection, thus realizing the thermal insulation effect. The data covered by this intellectual property focuses on information for solving the problem of blocking heat (cold) transfer of products, and is collected via the aforementioned dedicated temperature measuring instrument. Algorithm for heat loss rate: Leave the product in an unlid state at a specified ambient temperature of 20℃±5℃ for no less than 30 minutes, then fill it with boiling water (100℃) until the water level reaches the lower end of the sealing lid (stopper). Tighten the seal immediately when the measured water temperature inside the product reaches 95℃±1℃. Under the same ambient conditions, measure the water temperature inside the product after a specified period of time. Water temperature is measured using a thermocouple placed in the hot water to generate electrical signals, which are then converted into temperature data via a data acquisition instrument combined with computer software and presented to users. Algorithm for actual thermal insulation performance: Heat loss rate (J/s) = [Specific heat capacity of water (4.2 J/(g·℃)) × Nominal volume (mL) × 1 g/mL × Temperature difference ΔT (℃) over the specified measurement time] / (Measurement time (h) × 3600 s/h) Actual heat loss rate (J/s) = [Specific heat capacity of water (4.2 J/(g·℃)) × Measured volume (mL) × 1 g/mL × Measured temperature difference ΔT (℃) over the specified measurement time] / (Measurement time (h) × 3600 s/h)
