Anti-oxidation impregnation process of graphite mold for 3d glass mobile phone backboard
The invention discloses an anti-oxidation impregnation process of a graphite mold for a 3d glass mobile phone backboard. The anti-oxidation impregnation process comprises the following steps: S1, pretreatment of a graphite mold sample: polishing, cleaning and drying or firing the graphite mold sample which is cut into a fixed size by a diamond wire cutting machine; s2, vacuum impregnation treatment: putting the graphite mold sample pretreated in the step S1 into an impregnation reaction kettle, closing a valve, tightening a kettle cover by using a handle, vacuumizing, opening an air outlet, and vacuumizing by using a vacuum pump until the vacuum degree is more than 0.09 Mpa. The impregnation kettle capable of controlling the pressure and the temperature is used for impregnating the graphite mold sample, the impregnation liquid enters pores in the graphite according to the vacuum self-adsorption principle, and the components of the impregnation liquid are dispersed in the pores in the graphite after the heat treatment curing process, so that the invasion of oxygen into the graphite mold is slowed down; and the service life of the graphite mold under high-temperature use is prolonged.
本发明公开了一种用于3d玻璃手机背板的石墨模具的抗氧化浸渍工艺，包括以下步骤：步骤S1：石墨模具样品的前处理：将用金刚石线切割机切割成固定大小的石墨模具样品进行抛光、清洗和干燥或灼烧处理；步骤S2：真空浸渍处理：将步骤S1进行预处理过后的石墨模具样品放入浸渍反应釜中，关闭阀门，使用手柄将釜盖拧紧后抽真空，打开出气口用真空泵将真空度抽至0.09Mpa以上。本发明通过一种可以控制压力、温度的浸渍釜对石墨模具样品进行浸渍，利用真空自吸附原理使得浸渍液进入石墨内部孔隙，经过热处理固化工艺后浸渍液成分分散在石墨内部的孔隙，从而减缓氧气侵入石墨模具的内部，增加石墨模具在高温使用下的寿命。
