Ceramic Dewatering Forming Board for Paper Machine
As we know that the dewatering elements is the key component in paper machine, whose inner quality and the reasonable configuration on forming table are very important for good formation and effective dewatering, and its quality also directly affects the service life of the forming fabrics.
Design feature:
For many years, we have visited many large domestic paper mills many times, and made performance analysis & study on kinds of ceramic dewatering elements from home and abroad as well as main raw material characteristic study, thus the unique structure came into being.
Strong points:
1, Ceramic made of Al2O3 can be used as dewatering elements for the whole paper machine with speed lower than 1300m/min, and as foils when speed is less than 1200m/min, while SiC and SiN dewatering elements are design for higher speed.
2, Imported ceramic segments with Al2O3 purity more than 99.5%.
3, Imported adhesive has strong resistant to high temperature and chemical corrosion.
4, FRP main material is imported, it's technical data is up to same equality level as overseas like products.
5, Piano-key if effectively avoided by the unique dovetail structure.
6, The surface roughness after fine polishing: Ra is less than 0.4um (Al2O3); Ra is less than 0.15um(SiC, SiN)
7, Exact precision ensures the same dewatering elements are completely interchangeable.
Technical parameters:
Advanced design concept
Low friction coefficient
Stable T-bar structure
High strength glass fiber base
No piano key thanks to dovetail groove structure
Precisely machined and easy to replace
Angle can be adjusted
Low adhesive rate of pulp fiber and filler particles
Effectively protect the wire
SS304/321 stainless steel box
Different welding method and processing way are adopted for different box body
Box body flatness is smaller than 0.3mm/m2
