中文摘要 | 本研究在製作陶殼模用之面漿與背漿中,以絹雲母為添加劑,探討其對泥漿基本性能及流變性能的影響,並與未添加添加劑之泥漿性能作比較。在陶殼模方面,於背漿內添加絹雲母添加劑,探討絹雲母對陶殼模基本性能影響。 研究結果顯示:對泥漿性能方面,無論添加於面漿與背漿,隨添加量的增加,泥漿pH值下降程度有減緩趨勢,故可延續泥漿壽命。對陶殼模性能方面,當絹雲母添加於背漿時,陶殼模高溫及濕態破斷強度隨添加量增加而增加,而殘留破斷強度有降低的趨勢;高溫透氣度方面,當添加於背漿時,其透氣度隨添加量增加而下降。 |
英文摘要 | The effects of sericite additive on the basic and rheological properties of the primary and backup slurry have been studied. Meanwhile, the properties of non-sericite added slurry have also been studied and compared. For ceramic shell mold, the effects of sericite additive on the properties of the backup slurry have been studied. Experimental results showed as follows: For the properties of the slurry, with the increase of the added amount, the trend of the decrease of pH for slurry was slow down; therefore, the life of the slurry was extended. As to the ceramic shell mold properties, when sericite was added to the backup slurry, both the green strength and hot strength were increased with the increase of the additive, and the trend for fired strength was reduced. As to the high temperature permeability, when added to the backup slurry, the permeability was decreased with the increase of the added sericite. |
