主要特点Main features:
The whole experimental cavity is in the glow generation region, uniform equivalent glow, this technology is a good solution to the traditional plasma work instability, In this way, the range and intensity of ionization is 100 times of that of the traditional PECVD, to the uneven accumulation of materials .
我司研制的回转PECVD系统能使整个实验炉体都处于辉光产生区，辉光均匀等效，这种技术很好的解决了传统等离子工作不稳定状态，这样离子化的范围和强度是传统PECVD的百倍，并解决了物料不均匀堆积现象
Use a quartz tube of a special shape (thin middle between two ends) as a reaction chamber for chemical vapor deposition.The furnace tube can rotate 360 degrees, Quartz stopper on the inner wall of the tube can help stir-fry the powder material and sintered more evenly, and the furnace body can be tilted to the left and right at a large angle, which is convenient to feed in and out, and the inclined angle is adjustable from 0 to 35 degree.
该款设备选用特殊形状(两头细中间粗)的石英管作为化学气相沉积的反应室;加热的同时炉管可360度旋转，管内壁有石英挡片帮助粉体材料翻炒有助于烧结得更均匀;而且炉体可左右大角度倾斜，方便进出料，倾斜角度在0~35°可调。
Widely used in the preparation of graphene at low temperature and the carbon coating experiment of powder material.
此款设备现广泛应用于低温石墨烯制备实验、粉体材料碳包覆实验。
