| titleOfInvention | Method for manufacturing porosity alumina tube |
| abstract | The present invention relates to a method for producing a porous alumina tube. A first step of mixing the alumina (Al 2 O 3 ) and the binder in a composition of 95: 5 wt%, 85: 15 wt%, or 90: 10 wt% to form a powder; A second step of adding water to the powder produced in the first step to knead the powder and vacuum-extruding the kneaded powder; A third step of drying the powder paste extruded in the second step through a roller at room temperature for 24 hours; And a fourth step of firing the composition dried in the third step at a temperature of 1400 ° C for 26 hours to 33.5 hours. The binder includes 67% by weight of CMC (sodium carboxymethyl cellulose), 20% by weight of PVA (polyvinyl alcohol) 14 wt%, dextrin 13 wt%, oil 3 wt%, and surfactant 3 wt%. Thus, a binder composed of CMC, MC, PVA, dextrin, oil (lubricating role) and a surfactant can be mixed with alumina and applied to a dehydration process through synthesis of a filter and a hydrophilic separator under mild conditions through vacuum extrusion. Thereby providing an effect of mass-producing an efficient and porous alumina tube. |
