3.第三种方法——简称“压入法”。特点是:设备简单,操作容易;赤磷的实收率可达70～85％。例如加入15％的赤磷,制得的磷铜含磷量约在11～13％范围,但这种方法需用较粗的铜管,这在一般工厂里不易找到。制法是这样: 1)制作铜管:选取内径在50～60毫米的铜管,切成一段一段,长度相当于坩埚深度的2/3,多备几根,用干布把铜管内外擦拭洁净。没有铜管,可

3. The third method - referred to as “pressed into law.” Features are: simple equipment, easy operation; the actual yield of red phosphorus up to 70 ~ 85%. For example, by adding 15% of red phosphorus, phosphorus phosphorus obtained in the range of about 11 ~ 13%, but this method requires thicker brass, which is not easy to find in the general factory. The system of law is this: 1) the production of copper: Select the diameter of 50 to 60 mm of copper, cut into sections, the length of the equivalent of 2/3 the depth of the crucible, prepare a few more, with a dry cloth copper wipe inside and outside Clean. No brass, can
