Abstract

SE FABRICAN DETERGENTES EN TABLETAS, A PARTIR DE UN SECUESTRANTE DE FOSFATO HIDRATADO, DE UNA BASE CAUSTICA, AGUA LIBRE Y, OPCIONALMENTE, AGENTES DE CARGA, COMBINANDO LOS PRODUCTOS Y FORMANDO TABLETAS CON LOS CONPONENTES SIN QUE LAS TABLETAS O EL DETERGENTE SUPEREN LOS 50 (GRADOS) C. EN UNA REALIZACION PREFERIDA DE LA INVENCION, EN LA CUAL SE INCORPORAN AGENTES DE CARGA, TODO EL AGUA LIBRE SE COMBINA CON LOS SECUESTRANTES DE FOSFATO, TANTO ANHIDROS COMO HIDRATADOS. UNA VEZ QUE EL AGUA HA SIDO ABSORBIDA POR LOS SECUESTRANTES, EL AGENTE DE CARGA Y LA BASE CAUSTICA PUEDEN AÑADIRSE Y FORMAR TABLETAS DE DETERGENTE. EL AGUA LIBRE SE UNE DE FORMA SUFICIENTEMENTE ESTRECHA AL SECUESTRANTE DE FOSFATO PARA NO REACCIONAR RAPIDAMENTE CON LA BASE CAUSTICA ANHIDRA, MANTENIENDOSE LA TEMPERATURA A MENOS DE 50 (GRADOS) C, LO CUAL EVITA A SU VEZ QUE EL AGUA DE HIDRATACION PRESENTE EN LOS FOSFATOS REACCIONE Y DEBILITE, POR TANTO LAS TABLETAS FORMADAS. DICHAS TABLETAS SE PUEDEN FORMAR ASIMISMO COMBINANDO EL AGENTE DE CARGA CON LOS AGENTES SECUESTRANTES DE FOSFATO Y AGUA Y AÑADIENDO POSTERIORMENTE LA BASE CAUSTICA, SI EL DETERGENTE SE ENFRIA Y SE MANTIENE SU TEMPERATURA POR DEBAJO DE LOS 50 (GRADOS) C, HASTA FINALIZAR LA REACCION CON EL AGUA Y LA BASE CAUSTICA LIBRE.DETERGENTS ARE MANUFACTURED IN TABLETS, FROM A HYDRATED PHOSPHATE SEQUESTRANT, FROM A CAUSTIC BASE, FREE WATER AND, OPTIONALLY, LOAD AGENTS, COMBINING THE PRODUCTS AND FORMING TABLETS WITH THE COMPONENTS WITHOUT THE TABLETS OR THE TABLETS DEGREES) C. IN A PREFERRED EMBODIMENT OF THE INVENTION, IN WHICH CARGO AGENTS ARE INCORPORATED, ALL FREE WATER COMBINES WITH PHOSPHATE SEQUESTERS, BOTH ANHYDRED AND HYDRATED. ONCE THE WATER HAS BEEN ABSORBED BY THE SEQUESTERS, THE LOAD AGENT AND THE CAUSTIC BASE CAN BE ADDED AND FORM DETERGENT TABLETS. FREE WATER IS STRICTLY CLOSED TO THE PHOSPHATE SEQUESTRANT TO NOT REACT FAST WITH THE CAUSTIC BASE ANHYDRA, MAINTAINING THE TEMPERATURE TO LESS THAN 50 (DEGREES) C, WHICH PREVENTS WHETHER THE PRESENT HYDRATION WATER REACT AND WEAKEN THEREFORE THE TABLETS FORMED. THESE TABLETS CAN ALSO BE FORMED BY COMBINING THE CARGO AGENT WITH THE SEQUESTERING AGENTS OF PHOSPHATE AND WATER AND ADDING THE CAUSTIC BASE SUBSEQUENTLY, IF THE DETERGENT COOLES AND MAINTAINS ITS TEMPERATURE BELOW THE 50TH GRADE WITH WATER AND FREE CAUSTIC BASE.
