A heat-resistant water-soluble lubricant suitable for high-temperature metal-working operations comprises a mixture of an alkali metal borate and an alkali metal phosphate but no oil, fat or gelatinous substance. The preferred composition consists of one part of sodium tetraborate and 5 to 20 pa...
Since significant absorption and reaction occurs only in the presence of water, the absorption efficiency strongly depends on the ratio of the evaporation rate to the absorption rate. At moderate excess 在calciumhydroxide高剩余二氧化硫吸收效率由干燥条件限制。 从重大吸收和反应在水面前仅发生,吸收效率强烈...
In order to predictably achieve a bacteria-free root canal system, it is necessary to use intracanal medicaments. Calcium hydroxide [Ca(OH)2] is the most common intracanal medicaments. It is effective against primary infections. However, its effectiveness against Enterococcus (E.) faecalis and ...
