Viscous liquid. Soluble in water and acid. Insoluble in alcohol. Used in the manufacture of vat dyes, fire retardants, welding rods, soaps, etc. used in the manufacture of electric welding rods, welding electrodes, vat dyes, and fire retardants. Used as a phosphor binder and soap filler for fluorescent screens. It is used as a catalyst and a binder for phosphor screens. It is mainly used for electron beam tube phosphor screen coating, and Chemicalbook can also be used as an auxiliary material for the manufacture of phosphors and conductive graphite emulsions. Mainly used in electronic instrument industry (picture tube), detergent, welding rod and other uses as protective coating (to prevent "blooming" that is salt surface crystallization). catalyst. adhesive. It is used as a detergent in the manufacture of glass and ceramics. The phosphor is glued to the picture tube and coated on the outside of the welding rod to overcome spattering.
