氧化锆粉的成型介绍

    氧化锆粉的成型介绍:

   干压成型对模具质量要求较高,首先要求模具硬度达到一定的要求。由于ZrO2 稳定料的颗粒很细,流动性差,因而对模具的光洁度要求很高,若光洁度达不到要求,则干压时影响料的流动,从而导致分层的出现。同时,若模具配合不好,间隙大,则由于ZrO2 粉料颗粒细,压制时粉料会从模具间隙中流出,从而造成模具四周的粉料少,这样压制时四周就不能压实,从而会因压力传递不一致而出现分层,故对模具的配合要求较高。   

   成型压力成型压力在ZrO2干压成型过程中是较关键的,压力太小和太大都不能压制出理想的坯体。压力太小,则烧后产品的密度小,产品收缩大,坯体压实程度不够容 易出现分层;而压力太大,坯体也容易出现裂纹、分层和脱模困难等现象。合适的成型压力需要通过生产实践来摸索。
