| titleOfInvention | Production method for alginate specialized for welding |
| abstract | The invention relates to a production method for alginate specialized for welding. In the production method, alginic acid is formed by an acidification method; then a secondary washing process is employed in a washing process after the alginic acid is formed by acidification; and a compound washing liquid is selected to wash again after the alginic acid is conversed into alginate by neutralization in a solid phase. The above improvements can effectively reduce the content of phosphorus, sulfur and chlorine in a finished product of the alginate. Acidification treatment is used to form alginic acid in the preparation method. Compared with a conventional calcification method, the production method provided by the invention omits a decalcification process, shortens a production period, and reduces working time. Besides, compared once washing in the prior art, the secondary washing process is employed after acidification, so that the content of phosphorus, sulfur and chlorine can be effectively reduced. The compound washing liquid is selected to wash the alginate after neutralization in the solid phase, so that the concentrations of inorganic ions such as phosphorus, sulfur and chlorine are reduced and the volume of the obtained alginate expands, thereby facilitating subsequent smashing. The particle size can easily reach below 75 [mu]m when the alginate is smashed, with little loss. |
