ceramic packings have great advantage of acid-& heat - resistance. it can withstand almost all kinds of acid up to 1000℃, except hf acid , and be widly used in the tower of dry, absorbing cooling, washing and recovery etc. in chemical, petrochemieal and metallurgical industry. random packings includ rasching ring, spiral ring, cross partition ring, pall ring, intalox saddle, supper intalox, casade ring, wheel ring, sk connecting ring, and conjugate ring. features: 1) excellent performances and stability in acid and other chemical corrosion conditions (acid-99.8%; alkali-92%) 2) stable chemical features and low rate of water absorption 3) can resist high pressure and high temperatures in production procedure 4) can resist the corrosion of almost all kinds of acids (including organic and inorganic acid, but except hf acid), organic dissolvent, and some alkali 5) special ceramic packing and has the characteristics of high temperature resistance, corrosion resistance, good mechanical strength 6) types: saddles, supper saddles, raschig rings, cross partition rings, pall rings, cascade rings, conjugating rings 7) widely used in petrochemical, acid, natural gas, aqueous cleaning, fine chemical, environmental protection, pharmaceutical, fertilizer, and metallurgical plants where they are widely used in the towers of drying, filter, absorbing, cooling, washing, and recovering 8) for mass transfer and severe acid corrosive applications
