Plastic rosette packing, also known as Teller rosette ring, it is an ellipsoidal filler formed by many circles surrounding it, with A stiffener in the middle and an "A" shape, which greatly improves the compressive strength of the rosette ring. At the same time, the Teller rosette ring packing has the advantages of high flux and low pressure of the general packing, but also can make the residence time of the liquid in the column longer because of the higher liquid holding capacity in the gap of the packing, so as to increase the contact time of the gas-liquid two phases and improve the mass transfer efficiency of the packing.
Customers can choose different materials such as polypropylene (PP), RPP(glass reinforced polypropylene), polyvinyl chloride (PVC), chlorinated polyvinyl chloride (CPVC), polyvinylidene fluoride (PVDF) and other plastic Teller rosette fillers according to the use conditions in the tower (such as temperature, pressure, media, etc.).
According to the conventional, the tower packing generally uses ceramic tower packing or conventional plastic tower packing, but the chlor-alkali industry to consider the corrosion
resistance. And ceramic fillers are not resistant to chlorine, hypochlorous acid, sodium hydroxide and sodium hypochlorite and other chlorine, alkaline compounds corrosion or oxidation, resulting in part of the system (such as chlorine system) after corrosion off powder and blocked pipes, equipment phenomenon.
Chemshun's various materials of plastic Teller rosette ring, PVC, CPVC material Teller rosette ring packing in addition to excellent chlor-alkali, but also has excellent resistance to chlorine, sodium hypochlorite oxidation, sodium hydroxide solution corrosion performance, and has high temperature resistance: PVC temperature resistance of 60℃, CPVC temperature resistance of 100℃. PVDF is resistant to 150℃. Its mechanical strength is good, high temperature and high pressure does not deform, can be widely used in caustic soda and chlor-alkali industry packing tower.
