Brief introduction about the application of Kaolin

与未煅烧高岭土相比，低温煅烧高岭土的结合水含量减少，二氧化硅和三氧化铝含量均增大，活性点增加，结构发生变化，粒径较小且均匀，与未煅烧高岭土填充NR胶料相比，低温煅烧高岭土填充NR胶料的硫化特性曲线基本一致，绍尔A型硬度不变，拉伸强度提高，两者的物理性能均达到运动鞋非透明鞋底行业标准的要求。

Compared with uncalcinated kaolin, low-temperature calcined kaolin has a reduced bound water content, an increase in silica and alumina content, an increase in active sites, a change in structure, a smaller and more uniform particle size. Compared with uncalcinated kaolin filled NR rubber, low-temperature calcined kaolin filled NR rubber has basically the same vulcanization characteristic curve, with unchanged Shore A-type hardness and increased tensile strength, Both physical properties meet the requirements of the industry standard for non transparent sports shoe soles.

目前陶瓷、橡胶、塑料、人造革、自水泥、耐火材料、化学等工业以及农业毋有广泛应用。随着对高蛉土选矿工艺的进一步提高，高岭土的应用范围将日趋广泛。煤田地质系统各单位，可以从实际情况出发，立足于煤系地层中高岭土资源及市场需求。高岭土是自然界中普遍存在的一种非金属矿，过去一般用于生产陶瓷，耐火材料以及少量掺入塑料，橡胶中作填料。随着国民经济各领域的日益发展，人们越来越重视高岭土的深度加工，因为这样不仅可以获取新的具有特殊性能的材料，而且还可提高经济效益。对高岭土进行深加工舳方法之一，即将巳淘洗和韧步烘干磨耪的高岭土进一步加热，焙烧，脱水，使其变成偏高岭土，用作塑料电缆科的填料，以提高电缆包皮的绝缘性能。常用的鞋类橡胶填充剂主要有有机填充剂和无机填充剂两种，前者包括再生胶和回收料等，后者包括白炭黑、碳酸钙、钛白粉、碳酸镁、氧化镁、炭黑和锌氧粉等。高岭土是近几年开发的一种新型橡胶制品填充剂。

At present, ceramics, rubber, plastics, artificial leather, self cement, refractory materials, chemical and other industries, as well as agriculture, are not widely used. With the further improvement of kaolin beneficiation technology, the application range of kaolin will become increasingly widespread. Each unit of the coalfield geological system can start from the actual situation and based on the kaolin resources and market demand in the coal measures strata. Kaolin is a non-metallic mineral commonly found in nature. In the past, it was commonly used to produce ceramics, refractory materials, and a small amount of added plastic and rubber as fillers. With the increasing development of various fields of the national economy, people are paying more and more attention to the deep processing of kaolin, because this can not only obtain new materials with special properties, but also improve economic benefits. One of the methods for deep processing of kaolin is to further heat, roast and dehydrate the kaolin that has been elutriated and tough step dried and milled to turn it into metakaolin, which can be used as filler of plastic cable family to improve the insulation performance of cable sheath. Common rubber fillers for footwear mainly include organic fillers and inorganic fillers. The former includes reclaimed rubber and recycled materials, while the latter includes white carbon black, calcium carbonate, titanium dioxide, magnesium carbonate, magnesium oxide, carbon black and zinc oxide. Kaolin is a new type of rubber product filler developed in recent years.

但是高岭土的所有应用都必须要经过加工，成为细粉，才能加入到其他材料中，完全融合。

However, all applications of kaolin must be processed to become fine powder before it can be added to other materials and fully integrated.
