METHOD OF EDGE-SEALING GYPSUM BOARD FOR CLEAN ROOM QUALITY |
摘要 |
<p>A method for coating the sawed edges of gypsum wallboard to prevent dusting of gypsum particles in clean rooms. The method includes applying a water-dispersible polymers to the sawed edges of gypsum wallboard. The polymer forms a water-insoluble salt through an ion exchange with the calcium found in gypsum wallboard. The result is a tough, tack free, fast-drying coating that substantially reduces the levels of airborne gypsum particles that come from the sawed edges of gypsum wallboards.</p> |
