石硫合剂波美浓度的测定通常使用波美比重计。波美比重计具有快速、简便、准确的特点,在生产上被广泛采用。然而。目前不少地方,尤其是农村难于买到波美比重计,给生产带来很多不便。利用波美浓度与普通比重的关系,也可以很简便地求得石硫合剂的波美度。其具体做法如下。取一大玻璃瓶,盛入1.0kg 清水,在水面处作一记号,然后倒去水,盛入等体积的石硫合剂母液。称出石硫合剂的重量 G(kg,精确到0.1g),则 G近似等于其普通比重。代入下列公式即可换算得出石硫合剂的波美浓度。
Determination of Baume concentration of lime sulfur mixture is usually used Baume. Baume meter with fast, simple and accurate features, is widely used in production. however. At present, quite a few places, especially the rural areas, are hard pressed to buy Baume and give a lot of inconvenience to production. The use of Baume concentration and the relationship between the proportion of ordinary, but also can be very simple to obtain the Baume degrees of sulfur-sulfur mixture. The specific practices are as follows. Take a large glass bottle, Sheng 1.0kg water, a marker at the water surface, and then poured the water into the same volume of lime sulfur mixture mother liquor. Weigh out the weight of stone sulfur mixture G (kg, accurate to 0.1g), then G is approximately equal to its ordinary gravity. Substitution of the following formula can be converted to obtain the sulfur Brimstone Baume concentration.
