In this paper,the crystalin rules of non-phsphate non-phosphate detergent bulider & layered sodun discate have been studies in 120 seconds at 800-900 c it was proved that pure layered sodiun disillcate can be synthesized in 120 seconds at 800-860c and the crystallin time can be shorten 5 times than early resuits Tihs is an effective way for preparing layened sodum disiicate XRD,SEM Ca2+ ion exchange,ph value and soil removal characterized the as-synthesized samples The experiments showed typical as-synthesi...
