hydrophobic perlite

is a private enterprise, which specializes in production of expanded perlite serial products. The company commits itself to the production and application development of the expanded perlite serial products. It passed the ISO9001:2000 Quality Management System Certification, which was judged by BVQI in 2003. The company possesses of many independent intellectual property rights. The processing equipments of the expanded perlite and the hydrophobic perlite produced by the cryogenic equipment adopt the computer-focused processing parameter to control the operation, thus the product quality is stable. The company can produce the type 40 expanded perlite stably, which is the only company having the ability of producing the type 40 expanded perlite and the hydrophobic perlite produced by the cryogenic equipment. The process of the production and construction on site adopts HSE controlment project.

The expanded perlite produced by the cryogenic equipment can be categorized into three types: type 40, type 50 and type 60, each of which corresponds with bulk density ≤40KG／m3,≤50KG／m3,≤60KG／m3,and they can be categorized into expanded perlite and hydrophobic perlite according to the condition that whether they are dealt with the hydrophobic process. The expanded perlite of the cryogenic serial produced by our company was awarded the high quality product in the field of China perlite in 2004.

The product type number 40, 50 and 60, the hydrophobic expanded perlite, are the high-technology product having the unique independent intellectual property rights in China, which are developed in allusion to the LNG boat adiabatic case. Our company and Hudong-Zhonghua Shipbuilding (Group) Company cooperated together to produce these perlite, whose capability index achieve the advanced level in the world. They were awarded the Shanghai High-tech Transfer Project in 2004. (project number:20040343, project level: A )

The hydrophobic expanded perlite is dealt with hydrophobic process by using the high-quality surface treatment chemicals on the basis of expanded perlite. The process can cut off the capillary transfer and the absorbability of the moisture effectively, and it is good for enhancing the long-term stability of the heat-resistant effect. It prolongs the internal period of the equipment examination and the longevity of the heat-resistant layer of the expanded perlite.

Since the products were put in the market, their excellent capability have received good reputation among the users home and abroad. They have been applied to the 900 thousand ton ethane equipment cold box of the Sino-British joint ventured Shanghai Saike Company(BP Company), two 1000m3 air , 2000m3 air separation equipments and cold boxes of Taizhou Dongfang Oxygen Plant, 3000m3 air separation equipments and cold boxes of Shanghai Baogang Oxygen Plant, 500 m3 air separation equipments and cold boxes of Shanghai Zhongyuan Group and so on. The products have good effects.

For the purpose of better developing the application of the products in the low temperature field, our company possesses the self-developed pneumatic filling conveyor of the expanded perlite which is used exclusively by the cold box. It has fast filling speed, small quantity of dusts. It saves labor and energy and provides expanded perlite filling services exclusively for the medium and great type of cold box users.
