煅燒高嶺土
我公司以優質的煤系高嶺土為原料，經過精選、超細、除雜、分級、煅燒等不同的工藝，生產出1250目、2500目、5000目等不同規格的產品，具有高白度、高分散性、高遮蓋力等特點，廣泛用于造紙、涂料、橡膠等行業�？刹糠痔娲伆追�。
煅燒后的高嶺土又較完整的六方片結構。良好的孔隙度、合理的粒度分布范圍和極佳的光散射性等特點。同時，由于白度高。磨耗值低、吸油性好，是一種優良的涂料顏色，在造紙行業中主要用于涂布的面涂。其具有降低生產成本，提高紙張性能，提高油墨吸收率，與其他組分有良好的相容性且自身粘度高的特點。
| 物化指標產品規格 | 白度（%） | 粒度 （2μm） | PH值 | 折射率 （%） | 水分（%） | 吸值油 |
| JN-D1250 | ≥91.0 | ≥1250 | 6.5-7.5 | 1.6 | ≤0.5 | 2.65 |
| JN-D3500 | ≥93.0 | ≥3500 | 6.5-7.5 | 1.6 | ≤0.5 | 2.65 |
Calcined kaolin
Our company with high quality coal measures kaolin as raw material, after selection, superfine, impurity removal, grading, calcination and other different processes, the production of 1250 mesh, 2500 mesh, 5000 mesh and other different specifications of products, with high whiteness, high dispersion, high hiding power and other characteristics, widely used in papermaking, coating, rubber and other industries. Can partially replace titanium dioxide.
The calcined kaolin has a more complete hexagonal structure. Good porosity, reasonable particle size distribution range and excellent light scattering. At the same time, due to the high whiteness. Low wear value, good oil absorption, is an excellent paint color, in the paper industry is mainly used for coating surface coating. It has the characteristics of reducing production cost, improving paper performance, improving ink absorption rate, good compatibility with other components and high viscosity.
| Product specification | whiteness（%） | Particle size（-2um) | PH | refractive index (%) | Moisture (%) | oil absorption value |
| JN-D1250 | ≧91 | ≧1250 | 6.5-7.5 | 1.6 | ≦0.5 | 2.65 |
| JN-D3500 | ≧93 | ≧3500 | 6.5-7.5 | 1.6 | ≦0.5 | 2.65 |
