Sagger forming process
The invention relates to the technical field of sagger forming, in particular to a sagger forming process. Comprising the following steps: customizing a carbon fiber preform according to drawing requirements; carrying out shaping treatment on the prefabricated body; carrying out permeation by adopting vacuum adsorption modified resin, and carrying out curing treatment; heating by using an inner mold and an outer mold, and pressing by using a press to meet the required size requirement; the pressed carbon/carbon saggar is subjected to carbonization high-temperature treatment, and the saggar with the density requirement of 1.5 or above is obtained; and the carbon/carbon saggar subjected to high-temperature treatment is subjected to surface coating treatment, and it is ensured that carbon fibers cannot fall off. The invention provides a batch production sagger forming process which is simple to operate, low in cost, short in production period, high in finished product efficiency and easy to copy by combining the requirements of the market on saggers for new energy carbon/carbon positive and negative electrode materials.
本发明涉及匣钵成型技术领域，尤其涉及一种匣钵成型工艺。包括以下步骤：按照图纸要求定制碳纤维预制体；对预制体进行定型处理；采用真空吸附改性树脂进行渗透，并固化处理；再采用内外模具加热进行压机压制处理满足所需尺寸要求；压制完成后的碳/碳匣钵进行碳化高温处理达到1.5以上密度要求的匣钵；将高温处理后的碳/碳匣钵进行表面涂层处理，确保碳纤维不会掉落。本发明结合了市场对于新能源碳/碳正、负极材料所用匣钵的的需求，提出了一种操作简单，成本低廉，生产周期短，成品效率高，易于复制的批量生产的匣钵成型工艺。
