Zhejiang Chang′an Renheng Technology Co., Ltd is founded in DEC. 2000, and the registered capital is RMB 32 million. We are new high-tech enterprise and principally engaged in the research, manufactory, sales and technical service of bentonite fine chemicals. We have 13 patents for invention and we build a complete set of quality management system, also Passed ISO 9001: 2008 quality management certification. And we were listed in Hong Kong stock exchange market in Jan. 2015. Zhejiang Chang′an Renheng Technology Co., Ltd is a professional deep fine bentonite resources service provider, the goal is to become the world′s top quality bentonite production supplier.

Zhejiang Chang′an Renheng Technology Co., Ltd has a rare ultra white, high performance, high quality bentonite mine. Total reserves amount to a million tons. Therefore, our bentonite products have excellent characteristics.

Mine Feature:

Ultra-white: Our bentonite mine has high purity, high whiteness, and high transparency property when be pregel, which reduces the defect of high cover rate of natural ore.

Natural: 100% pure inorganic products without any organic matter;

Batch stability: Our company carries out classification mining in strict accordance with the difference of raw ore quality, produces corresponding products of different quality ore and classifies the products to ensure the long-term stability of product quality.

Good performance: Bentonite is a non-metallic mineral with montmorillonite as the main mineral

Component. Montomrillonie structure is a 2: 1 type crystal structure composed of two siloxic tetrahedrons with a layer of alumina octahedrons. After the structure is subjected to the external shear force, the structure is damaged, thus achieving the rheological effect. Due to the special interlaminar structure of our raw ore, both organic and inorganic products are easy to diperse in the application process, achieving excellent rheological, anti-settling, thickening and other application properties.
