HB型高效干燥剂是中科院上海冶金研究所发明的目前国际上最优良气体干燥剂之一,已申请发明专利(中国专利局申请号86101504)。由上海冶金研究所监制,无锡高速分析仪器厂生产。高效干燥剂效果远比无水高氯酸镁优越,后者仅能使气体露点降至-50～60℃,而高效干燥剂可使气体露点降至—90℃(0.03ppm),其吸水的重量可达30%,始终保持疏松状态,气阻较小,而且随着吸水量增加气阻却不象无水高氯酸镁一样增加,反而有所下降,在0.05kg cm~(-2)的氮气压力下,通过直径为φ2厘米,高12.5厘米的干燥管,每分钟流量可达1升以上,完全能满足大部分应用领域的需要。吸水前后干燥剂的颜色由淡麦片变成深金黄色,故极易判别吸收
HB-type high-efficiency desiccant invented by Shanghai Institute of Metallurgy, Chinese Academy of Sciences is one of the finest gas desiccant in the world and has applied for invention patent (China Patent Office Application No. 86101504). Produced by Shanghai Institute of Metallurgy, Wuxi High Speed Analytical Instrument Factory. Efficient desiccant effect is far superior to anhydrous magnesium perchlorate, the latter only dew point gas down to -50 ~ 60 ℃, and efficient desiccant gas dew point can be reduced to -90 ℃ (0.03ppm), the water-absorbent Weight up to 30%, always remain loose, less air resistance, and with the increase of water absorption, air resistance does not increase as anhydrous magnesium perchlorate, but decreased, at 0.05kg cm -2 Nitrogen pressure, through the diameter of φ2 cm, 12.5 cm high drying tube, the flow rate per minute up to 1 liter or more, fully meet the needs of most applications. Desiccant water before and after desiccant color into dark gold from the light yellow, it is easy to distinguish absorption
