摘要:

Several proprietary dishwashing compounds, insolution, were found to appreciably attack commercial aluminum and aluminum utensils. Curves are shown illustrating also the corrosive effect on commercial aluminumofaqueous mixtures, in various proportions, of the salts usually present in such compounds. Sodium metasilicate was found to be a more efficient inhibitor than either trisodium phosphate or sodium pyrophosphate. Replacement of the soda ash by either trisodium phosphate or sodium pyrophosphate so as to give a final soda ash content of 40 to 45% was required before less sodium metasilicate than about 20% produced inhibition of the attack. The author concludes that the addition of about 25% sodium metasilicate to such proprietary compounds is advisable.
