In November 2000 this company was appraised as a high-tech enterprise by Qingdao Municipal Commission on Science & Technology.

　 On November 8, 2000 at the "National Environmental Protection Exemplary City Naming and Summary Assembly" held in Qingdao City, this company was judged to be an advanced organization.

　 The company's Technological Development Center has got better achievements in the year 2000. The trial production of WG-type colour silica gel with colour variability has begun. This product can be used as a good substitute for blue gel. With its stable quality and excellent properties, it has been exported to foreign countries. This research achievement has been reported to the State Patent Office for an invention patent. As for GF-type silica sol trial-manufactured by using a new technological process, its trial production is now under way, too. The quality of this product is excellent, featuring better transparency and homogeneous grain size, and hence favourable comments from users have been received.

　 On October 26, 2000 the pressure swing adsorptive silica gel and CSH silica gel developed by this company's Technological Development Center passed the city-level test for appraisal. All the experts at the appraisal meeting were of the same opinion that these two products filled the gap in China, and their quality reached the advanced level of the same products from foreign countries, therefore, putting these products into production would achieve considerable economic and social benefits. Pressure swing adsorptive silica gel, a key adsorbent for the high technology ? pressure swing adsorption, is used extensively in many industrial sectors mainly for separation and recovery of carbon dioxide and purification of gases. CSH silica gel is a kind of macro-porous silica gel containing water, used mainly as a raw material for producing micro-powder silica gel, and is now exported totally.
