DuPont's Sodium Hydride Process for Descaling Metals
Developed especially for the purpose and backed by continuous mill experience since 1941, the DuPont Sodium Hydride Descaling Process is essentially a chemically activated fused caustic soda cleaning bath. Advantages over conventional pickling and...
A roll mill is used to disperse fine ground ceramic color in an oily vehicle. The finished material in this form is used in the stencil or screen process of applying ceramic colors. This is an important step in the manufacture of ceramic colors.
A pad steam process developed by the DuPont Company's Dyestuffs Division, provides an economical method for continuous application of vat dyes to relatively small quantities of fine fabrics. A working model of the apparatus is here being...
