A new technology for producing PCC directly in the causticizing stage is reported in this paper.

介绍了一种苛化工段直接生产沉淀碳新技术。

The value of oil absorption, viscosity of Nujol mull, specific surface area, contact angle, distribution of particle size and dispersivity of the calcium carbonate particles were also characterized.

对改性前后碳粉体接触角、吸油率、蜡糊粘度、粒度分布、分散性等性能行了比较。

Calcifuge Describing plants that grow on soils containing very little calcium carbonate, such as sandy or peaty soils and cannot grow on basic substrates such as most chalk and limestone soils.

碳含量低土壤中生存植物，例如沙地或泥地中生长。这种植物之类碱性基质中不能生长。
