摘要
Considering the present domestic situation that medium density fiberboard(MDF) plants take for destructive testing in the laboratory to do density measurement, this paper presents a density on-line measurement and control technology of MDF based on single-chip microcomputer technique. A MDF production line of some factory was actually improved using this technique. The results showed that the density could be measured dynamically, and could realize the ability of density online detection of MDF and control the density within the specified scope.
