Abstract
SE REVELA UN METODO PAR TRATAR CORREAS SINFIN DE PAPELERAS Y SIMILAR PARA INHIBIR EL DEPOSITO DE MATERIALES PEGAJOSOS SOBRE LAS MISMAS. EL METODO COMPRENDE (A) APLICAR UNA SOLUCION ACUOSA QUE CONTENGA POR LO MENOS APROXIMADAMENTE 2 PPM DE UN POLIMERO CATIONICO; Y (B) APLICAR UNA SOLUCION ACUOSA QUE CONTENGA POR LO MENOS UN COMPUESTO SELECCIONADO DEL GRUPO FORMADO POR SURFACTANTES CATIONICOS Y NO IONICOS SOLUBLES EN AGUA; APLICANDOSE EL SURFACTANTE EN UNA CANTIDAD EFECTIVA PARA INHIBIR LA FORMACION DE DEPOSITOS DERIVADOS DEL POLIMERO CATIONICO. SE PREFIEREN LOS SURFACTANTES CATIONICOS. SE REVELA EL USO PARTICULAR DE SURFACTANTES SOLUBLES EN AGUA QUE TENGAN UN PESO MOLECULAR ENTRE APROXIMADAMENTE 200 Y 800 Y DE LA SIGUIENTE FORMULA GENERAL: R R N+ XR R EN LA QUE R SE SELECCIONA INDEPENDIENTEMENTE DEL GRUPO FORMADO POR HIDROGENO, GRUPOS DE OXIDO DE POLIETILENO, GRUPOS DE OXIDO DE POLIPROPILENO, GRUPOS ALQUILO DE ENTRE APROXIMADAMENTE 1 Y 22 ATOMOS DE CARBONO, GRUPOS ARILO Y GRUPOS ARALQUILO,SIENDO POR LO MENOS UNO DE LOS MENCIONADOS GRUPS R UN GRUPO ALQUILO DE POR LO MENOS APROXIMADAMENTE 8 ATOMOS DE CARBONO, Y EN EL QUE X-1 ES UN ANION, O 1/N DE UN ANION N-VALENTE. SE REVELAN COMO PARTICULARMENTE UTILES LAS COMPOSICIONES QUE COMPRENDEN LOS REFERIDOS POLIMEROS CATIONICOS Y DICHOS SURFACTANTES EN UNA RELACION DE PESO DE SURFACTANTE A POLIMERO CATIONICO DE APROXIMADAMENTE 50:1 A APROXIMADAMENTE 1:1.A METHOD FOR TREATING ENDLESS BELTS OF BINS AND SIMILAR TO INHIBIT THE DEPOSIT OF STICKY MATERIALS ON THE SAME. THE METHOD INCLUDES (A) APPLYING AN AQUEOUS SOLUTION CONTAINING AT LEAST APPROXIMATELY 2 PPM OF A CATIONIC POLYMER; AND (B) APPLY AN AQUEOUS SOLUTION CONTAINING AT LEAST ONE SELECTED COMPOUND FROM THE GROUP MADE UP OF CATIONIC AND NON-IONIC SURFACTANTS SOLUBLE IN WATER; APPLYING THE SURFACTANT IN AN EFFECTIVE AMOUNT TO INHIBIT THE FORMATION OF DEPOSITS DERIVED FROM THE CATIONIC POLYMER. CATIONIC SURFACTANTS ARE PREFERRED. THE PARTICULAR USE OF WATER SOLUBLE SURFACTANTS THAT HAVE A MOLECULAR WEIGHT BETWEEN APPROXIMATELY 200 AND 800 AND OF THE FOLLOWING GENERAL FORMULA: RR N + XR R IS SELECTED, INDEPENDENTLY BY THE GROUP FORMED BY HYDROGEN POLYGEN, POLYPROPYLENE OXIDE GROUPS, RENT GROUPS BETWEEN APPROXIMATELY 1 AND 22 CARBON ATOMS, ARILO GROUPS AND ARALKYL GROUPS, AT LEAST ONE OF THE MENTIONED GRUPS R IS AT LEAST APPROXIMATELY APPROXIMATE THAT X-1 IS AN ANION, OR 1 / N OF AN N-VALENT ANION. THE COMPOSITIONS UNDERSTANDING THE REFERRED CATIONIC POLYMERS AND SUCH SURFACTANTS IN A WEIGHT RATIO OF SURFACTANT TO CATION POLYMER OF APPROXIMATELY 1: 1 ARE DISCLOSED AS PARTICULARLY USEFUL.
