Method for quartz ceramic surface modification
The invention discloses a method for quartz ceramic surface modification, which comprises the steps that oxyhydrogen flame is adopted for conducting surface flame sintering treatment on quartz ceramic, and the quartz ceramic with a glass modification layer is obtained after sintering is completed. The glass modified layer is sintered on the surface of the quartz ceramic, so that the scratch resistance of the surface of the quartz ceramic is greatly improved, the quartz ceramic does not fall off, and the method can be suitable for occasions with higher cleanliness requirements; in addition, theglass modified layer solves the problem of pores on the surface of the quartz ceramic, so that the quartz ceramic has favorable permeation resistance.
一种用于石英陶瓷表面改性的方法，采用氢氧火焰焰对石英陶瓷进行表面火焰烧结处理，烧结完毕即得带有玻璃改性层的石英陶瓷；本发明在石英陶瓷表面烧结一层玻璃改性层，大大增加了石英陶瓷表面的耐刮擦能力，使石英陶瓷不掉粉，可适用于洁净度要求较高的场合；另外玻璃改性层解决了石英陶瓷表面的气孔，使石英陶瓷具备较好的防渗透能力。
