DRY CYLINDERS AND DRY FABRIC CONDITIONING – WIRETECH TECHNOLOGY
WIRETECH technology has been studied to eliminate contaminant deposits through the dryer cylinder conditioning, based on repellent coatings chemistry; Wiretech chemicals form a repellent and protective film on dryer cylinder surface; the repellent film reduces the surface tension on the cylinder inhibiting the adhesion of contaminant particles and making easier the paper releasing.
The film thickness is very low and it doesn’t reduce the efficiency of heating transfer rather, improving the surface cleaning, promotes a better heat exchange. Wiretech technology not only prevents contaminant adhesion but helps to lubricate the doctor blades, reducing friction between the blade and the dryer cylinder and dryer fabric.
Wiretech passivation chemistry is selected depending from PM characteristics, type of production, raw material in use. The product is applied through a bar with a special nozzle that prevent aerosol formation, it is pure dosed so the quantity of water introduced in the dry section is minimal.
