Applications:
●Detergent auxiliary for washing powder substituting for STPP:MDS can be used to pre-proportioning for spray drying or post-proportioning for producing low-density phosphorous-free washing powder, and also can be used as base powder for producing concentrated phosphorous-free or low-phosphorous washing powder by agglomeration method. The product has good detergency ability and can be used together with 4A zeolite as binary auxiliary for producing high/low density phosphorous-free washing powder.
●Detergent auxiliary for soap substituting for STPP: MDS can chelate calcium and magnesium ions in water quickly and thoroughly, consequently improving detergency ability of products. Moreover, it also has favorable anti- re-deposition performance.
●Detergent auxiliary for textile dyeing and printing: it can be used as chelating agent for pretreatment agent as oil remover and scouring agent etc, and also can be used as favorable hydrogen peroxide bleaching stabilizer.
●Detergent auxiliary for industrial cleaning agent: MDS can be used as basic material for industrial cleaning agent such as metal cleaning agent, heavy oil dirt cleaning agent and petroleum pipeline dredging and cleaning agent etc.
●Ceramic grinding aid substituting for STPP traditional STPP and sodium metasilicate: MDS is used as grinding aid, slurry water reducing agent and glaze deflocculating agent in ceramic processing, favorable for facilitating grinding and capable of reducing ball grinding time by 3 hours and effectively removing harmful calcium ions and magnesium ions in ceramic materials.
Packing, storage & transportation:
