摘要:
以胶磷矿伴生含钾页岩为原料,通过硫酸盐加入法制备表面霜化页岩砖. 利用毛细管张力,将页岩坯体中可溶性硫酸盐(霜化剂)带出表面,经过高温烧结,其硫酸盐涂层可以密实地覆盖于烧结后页岩砖表面,有效抑制了泛霜现象. 研究了五水合硫酸铜、六水合硫酸镁和七水合硫酸亚铁的不同加入量对霜化效果以及页岩砖抗折强度的影响,结果表明:不同硫酸盐及其不同加入量均具有不同的霜化效果,当霜化剂为六水合硫酸镁,质量分数为7%时,具有最佳的白霜效果. 3种霜化剂的加入均能有效提高页岩砖抗折强度,其强度值从15 MPa提高到20 MPa左右,但其加入量的大小对抗折强度的影响不大.
Abstract:
The surface frosted shale brick was prepared by sulfate addition method using collophanite bearing shale as raw materials. The soluble sulfate salt(frosting agent) in shale was carried out to the surface of the shale green body by capillarity. After sintering, the sulfate layer was coated tightly on the surface of shale brick, which could restrain the surface frosting of brick efficiently. The results show that the copper sulfate pentahydrate, magnesium sulfate hexahydrate and seven water ferrous sulphate and their different dosages have different frosting effects; the best frost layer is obtained with six hydrated sulfate magnesium of 7% mass percent; the doping of frost agent improves the rupture strength of the shale brick from 15 MPa to 20 MPa, but the dosage has little influence on the rupture strength.
