利名称:容量法等压吸附速率分析仪
利号:ZL 2019 2 1740137.5
保护点:
◆ BSD-PH 系列全自动高压气体分析仪 吸附腔与基准腔之间设置稳压装置,在吸附过程中基准腔的气体自动连续向吸附腔补充,了在吸附剂样品吸附测试过程中,测试腔的压力的恒定;
◆ 解决了传统静态容量法在测试时吸附腔压力持续降低,而无法测试等压吸附速率的问题;
◆ 可以获取吸附剂样品在等压条件下的吸附量及吸附速率,有助于研究吸附剂样品在恒定压力条件下的吸附动力学特性。
利名称:带过滤功能的填充棒及高温高压气体吸附仪
利号:ZL 2016 2 1252702.X
保护点:
◆ BSD-PH 系列全自动高压气体分析仪带过滤功能的填充棒内部设置过滤层,样品管抽真空过程中,气体先经过过滤层,然后进入仪器内部管路;
◆ 减小样品管死体积的同时避免样品抽飞污染仪器管路;
◆ 相比一次性阻隔式防污染垫片,该带过滤功能的填充棒可重复使用,且安装简单、结构可靠。
利名称:具有常压解吸附功能的高温高压气体吸附仪
利号:ZL 2016 2 1252704.9
保护点:
◆ BSD-PH 系列全自动高压气体分析仪具有常压解吸功能的高温高压气体吸附仪,对解吸气体分三个阶段采用三种装置进行,分别为游离气集气桶、解吸气流量传感器与解吸气集气桶、尾气集气桶构成;
◆ 解吸气的流量采用质量流量计和集气桶联合定量,提升了测试的准确度和数据的可靠性;
◆ 游离气集气桶采用排液法集气方式,实现瞬时大流量、高变化速率的冲击性气体的准确收集。
◆ 尾气集气桶采用排液法集气方式,实现瞬时微流量、长时间的微小流量气体的准确收集。
◆ 游离气、解吸气、尾气三者之间的转换采用系统自动控制;
◆ 软件数据处理功能,包括:实时绘制等温吸附曲线和常压解吸动力学曲线以及时间与常压解吸速度、常压解吸量曲线,计算吸附常数,记录常压解吸初速度和常压解吸终值。
利名称:一种维持液氮面恒定的液氮自动加注装置
利号:ZL 2018 2 0487469.6
保护点:
◆ BSD-PH 系列全自动高压气体分析仪通过传感器采集液面位置,反馈给机械液氮泵,进行液氮量的补充加注,从而实现杜瓦杯中液氮面恒定;
◆ 液氮加注速度快,液面控制且无过冲现象,无结冰堵塞管路的缺陷;
◆ 通过液氮自动补充加注的方式,相比传统的方式如杜瓦杯位移、温区变化量测试、液位传感器等,从根本上实现了液氮面恒定,从而确保了温区恒定,提高物理吸附仪的测试精度;
◆ 液氮自动加注装置,让物理吸附仪的液氮使用时间大幅延长,可支持平衡缓慢的微孔分析。
