High surface area, large heat capacity, low thermal expansion, resistant to corrosion and high temperature, ceramic honeycomb monoliths have been well used in chemical, metallurgical, gas and environmental protection industries.
The main usage is as follows: *Tower packing--With high surface area, even distribution of fluid and, efficient in mixture separation in chemical & petrochemical industries. *Catalyst carriers--Reduce the oxidation temperature of VOC in purification of industrial exhaust gases in RCO systems and automobiles. *Regenerative heat step-up transformer--Large heat capacity, low resistance to fluid and energy saving up to 40-70% in RTO systems. *Gas combustion distributor--Distribute the heat uniformly, and make the combustion completely.
It can save energy more than 10%. *Kiln furniture in refractory industries--Low bulk density and high thermal efficiency.

Pingxiang Global Chemical Packing Co., Ltd. (PGCP), is located in Gaokeng Industrial Park, Pingxiang, Jiangxi Province. It can produce ceramic, metallic and plastic tower packings, ceramic balls, molecular sieves, catalysts, activated alumina, petrochemical additives, activated carbons and filtering materials etc. Used in chemical and petrochemical industries.
Since established, the PGCP has made great achievements, developed a lot of new products, acquird the certificate of ISO9001-2000 and set up a pleasant cooperative relationship with the wide circles of the users, material suppliers, scientific research institutes and engineering design institutes. In 2006, we drafted chemical industry standards HG/T3986-2007 for Technology Condition of Plastic tower packing and HG/T3927-2007 for Industrial Activated Alumina with the National Non-metallic chemical equipment Standards Committee and the National Chemical Standard Committee. Our general engineer took part in drafting national chemical industry standard, that is HG/T 3683.1-2000 Industrial Ceramics Ball-Inert Ceramics Ball and HG/T 3683.3-2000 Industrial Ceramics Ball-Perforated Ceramics Ball. The new developing products HQ-HK slotted & perforated ceramic balls, high efficiency HQ-HK slotted & perforated supporting agent and high efficiency HQ-HK slotted & perforated protecting agent have the national patent, the number is ZL2005 3 0048184.0. Besides these ones, we have other patent products, that is HQR ring (ZL 2005 3 0048180.2) and HQ eight columns arcs link (ZL2006 3 0147956.0).
Based on the long history, the scientific management, the strong technical forces and the advanced equipments, the PGCP has wined much praises and trust from the customers by its first-class products and the perfect services.
