本文介紹了液状石蜡和硬脂酸镁等70种不同物质試驗的結果。试驗是在装有3/8时的平面冲模压片机中进行的。总压力800到1200kg。下压片(每平方厘米,1.100到1.700kg),受試颗粒选用10—12目或较細粉,液体潤滑剂和溶液以噴雾法噴洒于滾动颗粒。在所有实例中潤滑意味着在两摩擦着的表面投入少量的适宜物质,目的是减少发生于界面的摩擦。润滑剂的作用通常认为有两种作用,第一,为液体(或hydrodynamic)润滑如烃类一液状石腊;
This article describes the test results of 70 different substances, such as liquid paraffin and magnesium stearate. The test was carried out in a flat die press with 3/8 loading. Total pressure 800 to 1200kg. Under the tablets (1.100 to 1.700kg per square centimeter), the test particles are selected 10-12 mesh or finer powder, liquid lubricant and solution sprayed on the rolling particles. Lubrication in all instances means that a small amount of suitable material is applied to the two rubbed surfaces in order to reduce the friction that occurs at the interface. The role of the lubricant is generally considered to have two roles, first, for liquid (or hydrodynamic) lubrication such as hydrocarbon-liquid paraffin;
