Preparation process of high-strength hydrophobic ceramsite
The invention discloses a preparation process for high-strength hydrophobic ceramsite. The preparation process comprises the following steps: 1, selecting raw materials including, in parts by weight, 10-20 parts of clay powder, 10-20 parts of tuff, 30-50 parts of fly ash and 40-60 parts of a blank, and carrying out mixing and crushing; 2, sieving mixed powder obtained in the step 1 to obtain coarse powder and fine powder; 3, putting the fine powder obtained in the step 2 into a stirrer, then gradually adding manganese dioxide and barium oxide powder, and then carrying out full stirring for 20-30 minutes; and 4, putting the coarse powder obtained in the step 2 into a stirring barrel. According to the preparation process of the high-strength hydrophobic ceramsite, waste sludge and slag of chemical enterprises are selected as raw materials, so the purpose of waste utilization is achieved, and secondary pollution caused by waste is prevented; hydrophobic process treatment is conducted through hydrophobic mixed liquid, so the water absorption rate of the ceramsite is remarkably reduced; and in a sintering process, sintering strength and performance are improved, and therefore, the density, the strength and the hydrophobicity of the ceramsite are improved and a spherical particle surface is smooth.
本发明公开了一种高强度憎水性陶粒制备工艺，包括以下步骤：按照重量份数配比选取以下原料：粘土粉10‑20份，凝灰岩10‑20份，粉煤灰30‑50份，坯料40‑60份，进行混合破碎处理；将步骤1中得到的混合粉末过筛得到粗粉和细粉；将步骤2中得到的细粉放置在搅拌机中，然后逐步添加二氧化锰和氧化钡粉末，然后充分搅拌20‑30min；将步骤2中所得的粗粉放置在搅拌筒内。该高强度憎水性陶粒制备工艺，通过选用化工企业废料污泥和矿渣作为原料，达到废物利用目的，防止废物造成二次污染，通过采用了憎水混合液进行憎水性工艺处理，显著降低陶粒的吸水率，在烧制过程中，提高烧结强度和性能，从而本发明提高陶粒的密度、强度和憎水性，球粒表面光滑。
