Transparent zeolite, there is a new molecular sieve (certified), there is a new zeolite molecular sieves by Shanghai Limited. Shanghai new molecular sieve Limited (www.molsionms.com) is specialized in the "sieve" of the enterprise, the company of "honesty, hard service" concept, to provide you with the highest quality products and services. Welcome to inquire! Contact: Mr. Pan. 1.3 Adsorption performance evaluation - Shanghai Co., said there is a new molecular sieves 4A molecular sieve placed to take a certain amount of 1mol / NH4Cl solution in L, 40 ℃ water bath and stir 6h, vacuum sand filtration, washed with water until the filtrate until no Cl- (with 0.1mol / Detection of L AgNO3 solution), 80 ℃ 4h molecular sieve structure was dried, calcined at 500 ℃ 2h. After the molecular sieve was then treated surfactant solution is placed 0.1mol / L in, 40 ℃ water bath was stirred for 24h, after sand filtration in vacuo, washed with water until the filtrate until no Br- (with 0.1mol / AgNO3 solution L of detection) molecular sieve function, carbon dioxide, water vapor is adsorbed by the selective adsorption of oxygen is passed through the adsorption column into the oxygen storage tank, after concentration, flow rate and pressure detected as the product gas output. The use of single-chip timing control valve switching commutation achieve pressure adsorption, desorption of the equalizing process. Also designed the process of signal detection equipment operation, human-computer interaction information, troubleshooting and alarm systems and other functions. Product oxygen concentration above 90%, the concentration in the low flow output up to 96%. 55dB less noise in the machine, with a timer, alarm, oxygen and pulse rate detection and atomization administration functions.
