【摘要】 以水作为稀释剂,三乙醇胺等几种表面活性剂为乳化剂,石蜡为原料,制备了幼苗移栽抗旱保活用乳化蜡。通过优化得到最佳配方:乳化时间40 min,搅拌速度为500~700 r／min,w(石蜡)=1.4％~1.8％,w(微晶蜡)=0.5％~1％,w(硬脂酸)=0.5％~1.2％,w(三乙醇胺)=0.4％~0.7％时得到乳化蜡产物。经使用后可在幼株表面形成一层极薄的蜡膜,从而减少水分的蒸发而保证其成活率。可使幼苗成活率达98％以上。更多还原

【Abstract】 A kind of emulsifier wax using for young plants transplant was prepared from paraffin wax, water as solvent for dilution, and triethanolamine as emulsifier. The optimum formulation was obtained as follows: w(paraffin wax) = l. 4%-1.8%, w(microcrystalline wax)=0. 5%-1%, w(stearic acid) =0. 5%-1.2% , w(triethanolamine) =0. 4%-0. 7% , under the conditions of emulsifying time 40 minand stirring speed 500 - 700 r/min. The emulsifier wax can give a protective coating to reduce the evaporation of water in young plants, and the young plant of transplant surviving rate can reach 98%.更多还原
