氧化鋯粉的成型介紹

    氧化鋯粉的成型介紹:

   干壓成型對(duì)模具質(zhì)量要求較高,首先要求模具硬度達(dá)到一定的要求。由于ZrO2 穩(wěn)定料的顆粒很細(xì),流動(dòng)性差,因而對(duì)模具的光潔度要求很高,若光潔度達(dá)不到要求,則干壓時(shí)影響料的流動(dòng),從而導(dǎo)致分層的出現(xiàn)。同時(shí),若模具配合不好,間隙大,則由于ZrO2 粉料顆粒細(xì),壓制時(shí)粉料會(huì)從模具間隙中流出,從而造成模具四周的粉料少,這樣壓制時(shí)四周就不能壓實(shí),從而會(huì)因壓力傳遞不一致而出現(xiàn)分層,故對(duì)模具的配合要求較高。   

   成型壓力成型壓力在ZrO2干壓成型過(guò)程中是較關(guān)鍵的,壓力太小和太大都不能壓制出理想的坯體。壓力太小,則燒后產(chǎn)品的密度小,產(chǎn)品收縮大,坯體壓實(shí)程度不夠容 易出現(xiàn)分層;而壓力太大,坯體也容易出現(xiàn)裂紋、分層和脫模困難等現(xiàn)象。合適的成型壓力需要通過(guò)生產(chǎn)實(shí)踐來(lái)摸索。
