多用途乳化蜡制备工艺研究

分析了影响乳化蜡稳定性的主要因素，如乳化剂的种类及其用量、乳化温度、搅拌速度、乳化时间等。开发了一种石蜡乳化的复合乳化剂。采用开发的复合乳化剂，研究了石蜡乳化的工艺条件，即复合乳化剂用量为石蜡用量的25％-30％，乳化温度80％，搅拌速度800r／min，乳化时间30min。按此条件制得的乳化蜡，外观为白色黏稠状液体，pH值为7，％（分层后乳化蜡的体积）VT（整个溶液体积）值为100％，稳定性好，分散性为一级，蜡含量在10％～20％：放置3个月无分层、无沉淀：任意稀释．稀释后30h不分层．

Study on Multipurpose Wax Emulsion Manufacturing Techniques

This article analyzes the main factors affecting the stability of wax emulsion,such as the types and dosage of emulsifying agents used,emulsifying temperature,mixing speed,emulsifying time,etc.Researchers have developed an emulsifying compound used for emulsifying paraffin.Using this emulsifying compound,they examined the technical conditions for emulsifying paraffin and came up with a conclusion that the amount of emulsifying compound used should be 25%-30% of that of paraffin used,the emulsifying temperature is 80℃ ,the mixing time should be 800r/rain and that the emulsification lasts 30rain.Wax emulsion produced under these conditions is a white ,viscous liquid with pH value at 7 and Vo（the volume of stratified wax emulsion）/VT（the volume of total solutions） ratio at 100%.The product has excellent stability and dispersibility（First Class） and the wax content ranges between 10% and 20%.Placed for three months,the product did not stratify or deposit and did not stratify 30h after being diluted with any proportions of water.
