摘要

提出了一种在等离子体反应器中制备玻璃微珠的技术。建立了等离子体形成气体氩流量和等离子体反应器功率对玻璃微珠分数组成的影响规律。结果表明，当等离子体形成气体的流速从1.0 m3/h增加到2 0 m3/h，电流强度从300 A增加到400 A时，超过630微米的组分由于凝固过程而增加。结果表明，在6000 ~ 8000k的等离子体高温作用下，颗粒发生完全熔化和球化，形成尺寸在80 ~ 1250微米的玻璃微珠。研究了玻璃微珠的显微硬度、耐酸性能和耐碱性能。

PLASMA TECHNOLOGY FOR THE PRODUCTION OF GLASS MICROBEADS BASED ON THE BREAKAGE OF CONTAINER AND GRADED GLASSES

A technology – based on the breakage of graded and container glasses – was developed for the production of glass microbeads in a plasma reactor. The regularities of the influence of the flow rate of plasma-forming gas argon and the power of the plasma reactor on the fractional composition of glass microbeads were established. It was shown that with an increase in the flow rate of plasma-forming gas from 1.0 m3/hour to 2,0 m3/hour and the current strength from 300 A to 400 A, the amount of fraction over 630 microns increases due to coagulation processes. It was established that under the influence of high plasma temperatures, about 6000-8000 K, complete melting and sphering of particles occur with the formation of glass microbeads ranging in size from 80 microns to 1250 microns. The microhardness, acid resistance and alkali resistance of glass microbeads were investigated.
