DESCRIPTION
THE TREATER CARRIES OUT THE IMPREGNATION OF GLASS CLOTHES WITH EPOXY RESIN.
THE MAJOR INNOVATION OF TREATER CONSISTS IN THE FACT THAT THE NECESSARY
THERMAL ENERGY FOR EVAPORATION OF SOLVENT AND POLYMERIZATION
IS REALIZED BY ELECTRICAL RADIANT PANEL.
USING ELECTRICAL ENERGY AS PRIMARY THERMAL SOURCE IS MUCH EASIER THAN ADOPTING
ANY OTHER SOURCE GENERALLY USED IN SUCH PLANTS, LIKE DIATHERMY OIL.
THE RADIANT PANELS OF TREATER ARE TOTALLY SAFE , BECAUSE OF THEIR SPECIAL
CONSTRUCTION.
PANELS ACHIEVE THE HIGHEST YIELD PRODUCTION AT THE SAME TIME;THEREFORE
IT POSSIBILE TO SAY THAT,WITH ABOUT 4
Kw PER
M², SYSTEM OBTAINS THE NECESSARY RESULTS
BOTH IN PHASE OF SOLVENT EVAPORATION AND POLIMERIZATION,
WITH LEAST CONSUMPTION OF ENERGY.
THE MATERIALS OF THE PANEL ARE CONSTRUCTED TO TRANSMIT ENERGY TO PREPREG
IN FORM OF ELECTROMAGNETIC LONG WAVES,PARTICULARLY SUITABLE FOR THEIR PURPOSE.
AS A MATTER OF FACT THE RESIN AND THE SOLVENT, WHICH IS CONTAINED IN THE RESIN,
CAN BE EATED FIRST FROM THE INSIDE AND THEN ON THE SURFACE: THEREFORE THE
PRODUCTS MADE BY TREATER DO NOT SHOW ANY TRACE OF SOLVENT
AFTER THE RESIN POLIMERIZATION.
THIS DOES NOT USUALLY HAPPENS TO THE PRODUCTS MADE BY TRADITIONAL WAYS.
PROCESS MADE BY TRADITIONAL SYSTEM CREATES A KIND OF BARRIER THAT PARTIALLY
PREVENTS THE EVAPORATION OF SOLVENT REMAINED INSIDE THE PREPREG (BUBBLES).
IT CAUSES A QUALITY PROBLEM WHEN THE COPPER FOIL IS PRESSED ONTO THE RESINS
DURING THE BONDING PROCESS.
SAFETY OF TREATER MACHINE
AS KNOWN, THE EVAPORATION OF SOLVENT FROM PREPREG INCREASES THE CONCENTRATION
OF THE SAME IN THE DRYING STATION.
CONCENTRATION COULD REACH SUCH A HIGH LEVEL THAT COMBUSTION OF THE SAME
COULD BE PROVOKED WITH THE RISK OF AN EXPLOSIVE CHAIN REACTION, IT IS NECESSARY
TO INTRODUCE PURE AIR IN SUCH A QUANTITY ABLE TO EXTRACT MIXED-AIR SOLVED
WITHOUT COMPROMISING THE DYNAMIC STABILITY OF DRYING TOWER ATMOSPHERE.
THE TEMPERATURE OF THE AIR INTRODUCED INTO THE DRYING SECTION WITH A TRADITIONAL
SYSTEM IS USUALLY AT 70°C,BECAUSE IT IS ALSO NEEDED TO HEAT THE PREPREG ITSELF.
IN CASE OF TREATER THE TEMPERATURE OF THE AIR IS ABOUT 100-120°C,CONSEQUENTLY
THE VOLUME IS REDUCED IN FUNCTION OF NORMALIZATION OF VALUE OF THE AIR ITSELF.
FOR TREATER IT IS ABOUT THE 60% OF TRADITIONAL TREATER.
ADVANTAGES
THE HOT AIR IS ABSOLUTELY NOT NECESSARY IN THE
TREATER DURING THE PHASE
OF POLYMERIZATION, BECAUSE THE RADIANT PANELS ARE GOOD ENOUGH.
IT IS OBVIOUS THAT THE REDUCED VOLUME OF AIR IN THE TREATER AS FOR EXTRACTION
OF SOLVENT AND POLYMERIZATION PHASE IS MUCH LESS EXPENSIVE (80-90%) THAN IN USUAL
SYSTEMS. THE USE OF THE RADIANT PANELS IS ALSO USEFUL TO CONTROL THE PRECISION
OF POLYMERIZATION. THE TREATER IS DIVIDED IN MODULES IN BOTH VERTICAL AND
HORIZONTAL DIRECTIONS, AND THE TEMPERATURE OF EACH MODULE IS AUTOMATICALLY
CONTROLLED TO OBTAIN THE BEST QUALITY OF THE FINISHED PRODUCTS.
PRACTICALLY SPEAKING,A PERFECT GEL-TIME IS OBTAINED
ON THE WHOLE SURFACE OF CLOTH.
