摘　　要：为适应绝缘子现代化大规模、连续、稳定生产的要求,有必要对胶装型瓷绝缘子用水泥胶合剂进行优化,以提高水泥胶合剂的早期强度,为此研究了水泥品种、硅灰掺量、减水剂种类以及减水剂用量对胶合剂早期抗折、抗压强度的影响。研究表明,快硬硫铝酸盐水泥早期强度发展比早强型普通硅酸盐水泥快,但初凝时间太短,不利于大规模作业。针对早强型普通硅酸盐水泥,在保证水泥胶合剂工作性能的情况下,随着胶合剂中硅灰掺量(相对于水泥用量)从0增加到10%,NF萘磺酸型高效减水剂掺量(相对于水泥)从0.25%增加到1.0%,胶合剂的早期强度逐渐增加。通过试验优选水泥胶合剂配方,验证其使用效果。In order to meet the requirements of modern large-scale,continuous and stable production,of the insulators,it is necessary to optimize the cement adhesive of the porcelain insulator and improve its early strength.Therefore,this paper studies the effects of cement types,silica fume and water-reducing agents on the early compressive and bending strength of the cement adhesive.The research result shows that the development of fast hardening early-strength sulphoaluminate cement is faster than that of early-strength ordinary Portland cement,and the Initial setting time is not enough for modern large-scale production.For the early-strength Portland cement,with the content of silica fume ranging from 0%to 10%and NF naphthalene sulfonic acid water reducing agent increasing from 0.25%to 1.0%,the early strength of the adhesive gradually increases under the condition of ensuring the working performance.Optimization of the adhesive formulas of the cement based on tests verifies the using effects.
