该粘土为富含针铁矿的杂粘土。呈鲜艳的杏黄色,质地细腻,悬浮性能好,是一种很好的天然化工颜料,不但畅销国内,而且长期出口日本。为扩大该粘土的应用范围,在陶瓷、油漆等应用领域进行了试验研究,取得了可喜的成果:制成了红色地板砖和不同黄色色系的釉料;用黄粘土代替部分氧化铁黄和体质颜料,制成了橙黄地板漆,各项技术指标符合化工部部颁标准,且每吨油漆降低原料成本60元左右。 The clay is goethite-rich heterotrophic clay. Vivid apricot, fine texture, good suspension performance, is a very good natural chemical pigment, not only sold in the country, but also long-term exports to Japan. In order to expand the scope of application of the clay, experimental research has been carried out in the fields of ceramics, paints and the like, and gratifying achievements have been made: a red glaze tile with different yellow color and a yellow glaze is prepared; yellow clay is used to replace part of yellow iron oxide and Physical pigments, made of yellow orange floor paint, the technical indicators in line with Ministry of Chemical Industry ministerial standards, and reduce the cost of raw materials per ton of paint about 60 yuan.
