Process and assembly to clean and impregnate dewatering belts, sieves or press belts used in manufacture of cardboard, paper or tissue paper

摘要

#CMT# #/CMT# In a process to impregnate a moving web of cardboard, paper or tissue paper the web is first exposed to a cleaning agent jet (2) followed by exposure to a chemical impregnation agent (3). #CMT# : #/CMT# Also claimed is a commensurate impregnation assembly in which the treatment zone jets move transverse to the direction of web movement. The cleaning and chemical treatment processes are simultaneous. #CMT#USE : #/CMT# Process and assembly to clean and impregnate dewatering belts, sieves or press belts used in manufacture of cardboard, paper or tissue paper. #CMT#ADVANTAGE : #/CMT# The process and assembly maximise the efficiency of treatment application. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The drawing shows the general arrangement of the cleaning and chemical impregnation assembly. 1 : Endless belt 2 : cleaning water jet 3 : chemical agent jet 4 : feed pipe 5 : feed pipe 6 : pump 7 : pump 10 : valve 16 : chemical agent reservoir.
