【摘要】：選用液體石蠟為油相,油酸鈉和十六烷基三甲基溴化銨(CTAB)作為乳化劑,利用高速攪拌和超聲乳化的方法制備了一種新型液體石蠟乳液作為冰漿蓄冷介質(zhì)。電導(dǎo)率測試表明:該乳液為O/W型,乳液的D50粒徑為1.56μm。在乳液中添加乙醇和丁醇可有效抑制冰漿粘附聚甲基戊烯(PMP)、玻璃和不銹鋼燒杯壁面。乳液在解除過冷后的初期,冰漿在不銹鋼燒杯中形成速度最快,在PMP燒杯中形成速度最慢。在解除過冷相同時間內(nèi),添加乙醇的乳液體系蓄冰率(IPF)比添加丁醇的高,但隨著結(jié)晶時間的增加,差值逐漸減小。解除過冷3 h后冰粒呈顆粒狀,IPF在55%~65%之間,具有良好的流動分散性。
[Abstract]:Using liquid paraffin as oil phase, sodium oleate and cetyltrimethylammonium bromide (CTAB) as emulsifiers, a new liquid paraffin emulsion was prepared by high speed stirring and phacoemulsification.The electrical conductivity test showed that the emulsion was O / W and the particle size of D50 was 1.56 渭 m.The addition of ethanol and butanol in emulsion can effectively inhibit the adhesion of ice slurry to PMP, glass and stainless steel beaker wall.In the early stage after the release of the supercooled emulsion, the ice slurry formed the fastest in the stainless steel beaker and the slowest in the PMP beaker.At the same time, the ice storage rate (IPF) of the emulsion added with ethanol was higher than that of butanol, but the difference gradually decreased with the increase of crystallization time.The IPF of ice particles was between 55% and 65% after 3 h of supercooling, which showed good flow dispersion.
