双室真空镀膜机是真空镀铝制镜的专用设备。本设备的研制成功，为应用“以铝代银”制镜新技术提供了一种新型设备。工作周期短，容量大，生产效率高，可适应多种玻璃规格，经过百余次蒸镀试验，工艺基本稳定，已移交用户生产，经国内有关部门进行技术鉴定，一致认为结构合理，具有国内先进水平。 本文对双室真空镀膜机的主要技术指标，结构特征，镀膜工艺分析及铝镜与银镜的比较等方面作了重点介绍。
Double-chamber vacuum coating machine is a vacuum-coated aluminum mirror special equipment. The successful development of this equipment provides a new type of equipment for the application of the new technology of “mirroring on aluminum” mirror system. The work cycle is short, the capacity is large, the production efficiency is high, it can adapt to a variety of glass specifications, after a hundred times of evaporation test, the process is basically stable, has been handed over to the user for production, and has been technically appraised by relevant domestic departments. Advanced level. In this paper, the main technical indicators, structural characteristics, analysis of coating technology and the comparison between aluminum mirrors and silver mirrors are introduced in this paper.
