NC-gauze packing is an important milestone of the development of clear and

neat filling．This kind of filling consists of arranged web pieces pressed into

corrugation．Obliquity of corrugation is 30 or 45 and the neighbor two pieces are of

opposite directions．When filling into the column，upper and lower filling trays cross bv

90．It has advantages of high effectiveness，low pressure drop and large flow rate．This

product includes BX,CY types，generally used invacuum distillation，normal pressure

distillation and absorption processes of matters hard to separate or thermal senstive．
