Method for modifying pyrophyllite raw material
The invention provides a modification method of a pyrophyllite raw material, which comprises the following steps: step 1, coarsely crushing and warehousing the raw material: crushing pyrophyllite, bentonite and gangue raw stone one by one, controlling the particle size to be 1-3mm, and storing after crushing; step 2, mixing and stirring the raw materials in proportion: weighing the raw materials obtained in the step 1 in proportion according to the weight proportion: 80% of pyrophyllite, 15% of bentonite and 5% of coal gangue, and stirring and mixing uniformly after weighing; step 3, ultrafine grinding of the raw materials: the raw materials uniformly mixed in the step 2 are subjected to ultrafine grinding, and the particle size after grinding is divided into three levels to be controlled, namely 325 meshes, 1250 meshes and 4000 meshes; step 4, removing iron from the raw materials: respectively removing iron from the raw materials in the step 3, wherein the iron content is 0.25% or below; 5, calcining the raw materials: respectively calcining the raw materials in the step 4 at the highest calcining temperature of 1025-1200 DEG C for 0.5 hour; and step 6, performing sampling inspection on finished products, and packaging and warehousing the qualified products. The whiteness of the pyrophyllite raw material is improved, and then the quality of a ceramic product is improved.
本发明提供一种叶蜡石原料的改性方法，包括如下步骤：步骤1、原料粗粉碎、入仓：将叶蜡石、膨润土、煤矸石原石逐一粉碎，粒径控制在1‑3mm，粉碎后储存；步骤2、原料按比例混合、搅拌：将步骤1所得原料按比例称量，重量比例为叶蜡石80％、膨润土15％、煤矸石5％，称量后搅拌混合均匀；步骤3、原料超细研磨：将步骤2中混合均匀的原料超细研磨，研磨后粒径分为三个级别控制，分别为325目、1250目及4000目；步骤4、原料除铁：将步骤3的原料分别除铁，铁含量均在0.25％以下；步骤5、原料煅烧：将步骤4中的原料分别煅烧，最高煅烧温度1025℃‑1200℃，保持0.5小时；步骤6、成品抽样检测，合格后包装、入库。本发明提升了叶蜡石原料的白度，进而提升陶瓷产品的质量。
