【摘要】：伊利石是一种黏土矿物,在陶瓷工业、造纸工业、橡塑制品填料、化肥工业、建筑业、环保行业、精细化工等领域有广泛应用,而且其应用范围还在不断拓展。伊利石为极性且亲水的矿物,然而塑料、橡胶等一些有机高聚物等具有非极性的疏水表面,如若将它们直接混合在一起,各自的疏水性不同,它们的相容性也有一些差距,使二种物料混合不均匀,导致伊利石黏土矿物的应用受到极大的限制。因此,在应用前需对伊利石进行改性处理,使其表面疏水性提高,才可用作有机高聚物和橡塑制品的填料。伊利石矿物原料以不同的方式进行改性处理,可分别用作橡胶、塑料、树脂、涂料等有机聚合物的填充原料或染色剂。近年来,伊利石的采选、增白、改性等综合研究及深层次开发利用已经开展起来。根据伊利石原矿品质的差异,经不同程度和不同方式的深加工,伊利石可作不同层次的应用。本文主要对伊利石表面改性及改性后的产物的性能进行了初步研究。采用一种新型的阳离子表面活性剂并用微波辅助的方法对精制后的伊利石进行改性,考察了不同温度及改性剂加入量分别为0.6CEC、1.0CEC、1.4CEC、1.8CEC时对改性效果的影响,对改性后的产物进行表征。通过XRD,SEM,IR,TG表征手段表明,伊利石表面改性成功。通过对伊利石/PVC的力学性能研究表明,在改性剂加入量为1.0倍CEC、伊利石添加量为6phr时效果最佳。同时,伊利石原矿土呈粘土状,掺杂石块和植物枝干等杂质,在进行改性之前先对伊利石原矿进行打浆、精制。并结合实际生产需要对伊利石矿土的水力打浆生产设备进行设计,确定了年处理矿土量为5万吨设备的结构及参数,转筒筒体直径3 m,长度10 m,螺旋推进板高度0.5 m,相邻板间距0.5 m,转筒转速0.3 m/s。对设备主要部件进行说明,提出了设备制造、安装、操作时的注意事项。
[Abstract]:Illite is a clay mineral, which is widely used in ceramic industry, paper industry, rubber and plastic products packing, chemical fertilizer industry, construction industry, environmental protection industry, fine chemical industry and so on. Illite is a polar and hydrophilic mineral, but some organic polymers such as plastics and rubber have non-polar hydrophobic surfaces if they are directly mixed together. Because of their different hydrophobicity and their compatibility, the two materials are mixed inhomogeneously, and the application of Illite clay minerals is greatly restricted. Illite must be modified to improve its hydrophobicity before it can be used as fillers for organic polymers and rubber and plastic products. Illite mineral raw materials are modified in different ways. Can be used as rubber, plastic, resin, paint and other organic polymer filling raw materials or chromatin. In recent years, Illite selection, whitening. Comprehensive research and deep development and utilization have been carried out. According to the quality difference of Illite ore, it has been processed in different degree and in different ways. Illite can be used in different levels. In this paper, the properties of the surface modification and the modified products of Illite are studied. A new cationic surfactant and microwave assisted method are used to refine the Illite. The Illite was modified. The effect of different temperature and the amount of modifier on the modification effect was investigated when the content of the modifier was 0.6 CEC 1.0 CEC 1. 4 CEC 1. 8 CEC. The modified product was characterized by XRDX SEM IR TG. The results showed that the surface modification of Illite was successful and the mechanical properties of Illite / PVC were studied. When the amount of modifier is 1.0 times CECand the content of Illite is 6phr, the effect is the best. At the same time, the Illite original soil is clay like, mixed with impurity such as stone and plant branch. Before the modification, the Illite raw ore was pulped and refined, and the hydraulic beating production equipment of Illite soil was designed in combination with the actual production. The structure and parameters of the equipment for treating 50,000 tons of ore soil per year are determined. The diameter of the cylinder is 3 m, the length is 10 m, the height of the spiral propelling plate is 0.5 m, and the distance between the adjacent plates is 0.5 m. The rotation speed of the rotary cylinder is 0.3 m / s. The main components of the equipment are described, and the points for attention in the manufacture, installation and operation of the equipment are put forward.
