[vc_row][vc_column][vc_column_text]A Concentrol realitzem estudis en els nostres laboratoris per a avaluar l’efic\u00e0cia de les nostres solucions. Mitjan\u00e7ant aquests assajos, podem observar el rendiment de les diferents refer\u00e8ncies del nostre cat\u00e0leg i comparar-les amb les caracter\u00edstiques i resultats de productes de la compet\u00e8ncia. Aix\u00ed, podem oferir la millor relaci\u00f3 qualitat-preu del mercat, al mateix temps que resolem les necessitats del sector.<\/span><\/p>\n

A continuaci\u00f3, es presenten els resultats de dos estudis elaborats en laboratoris de Concentrol. En el primer, veurem el rendiment de Emultrol DFM DV-1 S comparat amb un antiespumant refer\u00e8ncia del mercat, utilitzant com a mitj\u00e0 un detergent de rentavaixella. En el segon assaig, es compara l’efectivitat antiespumant al llarg del temps de Emultrol DFM DV-30, Emultrol DFM DV-1 i l\u2019antiespumant de la compet\u00e8ncia..<\/span><\/p>\n

Totes dues refer\u00e8ncies de Concentrol s\u00f3n solucions de gran rendiment per a mitjans adversos amb tensioactius (elevada acidesa o elevada alcalinitat), com s\u00f3n la deterg\u00e8ncia i els suavitzants t\u00e8xtils.<\/span><\/p>\n

 <\/p>\n

Assaig comparatiu antiespumant entre Emultrol DFM DV-1 S i un antiespumant refer\u00e8ncia del mercat al mig detergent per a rentavaixella<\/b><\/p>\n

En aquest estudi es compara l’efectivitat antiespumant del producte Emultrol DFM DV-1 S, fabricat per Concentrol, amb l\u2019antiespumant de la compet\u00e8ncia.<\/span><\/p>\n

Per a la determinaci\u00f3 de l’efectivitat antiespumant dels diferents productes, es realitzen assajos de macroespuma basats en el m\u00e8tode d’injecci\u00f3 de gas comprimit, utilitzant com a mitj\u00e0 el detergent per a rentavaixella.<\/span><\/p>\n

 <\/p>\n

Assaig de formaci\u00f3 de macroespuma<\/b><\/p>\n

Per a la realitzaci\u00f3 del seg\u00fcent estudi s’opta pel m\u00e8tode d’injecci\u00f3 de gas comprimit: es pesen 50 g del mig detergent en un got de 200 ml de volum m\u00e0xim, s’addiciona l\u2019antiespumant corresponent (dosi 0,2%) i s’injecta aire mitjan\u00e7ant un difusor de gasos (pressi\u00f3: 0,3 kg\/cm\u00b2; cabal: 0,05 l\/min).<\/span><\/p>\n

A continuaci\u00f3, es mesura l’augment de l’escuma formada passats 30 segons. La prova es torna a repetir passats 15 minuts per a avaluar l’estabilitat de l’efecte antiespumant amb el temps. L’assaig conclou amb aquests resultats:<\/span><\/p>\n

 <\/p>\n

Gr\u00e0fic 1. En aquest gr\u00e0fic es mostren el volum d’espuma format en l’assaig de formaci\u00f3 de macroespuma al mig detergent rentavaixella amb cadascun dels diferents antiespumant utilitzats en aquest estudi.<\/span><\/i><\/p>\n

\"ANTIFOAMING<\/span><\/p>\n

Com es pot observar, <\/span>el volum d’espuma format del mitj\u00e0 sense antiespumant desborda r\u00e0pidament el volum del got utilitzat (200 ml).<\/b> Utilitzant l\u2019antiespumant de refer\u00e8ncia del mercat s’observa que la quantitat d’escuma es mant\u00e9 als 30 segons en 80 ml. No obstant aix\u00f2, <\/span>si repetim l’assaig de formaci\u00f3 de macroescuma passats 15 minuts, el volum d’escuma desborda el volum del got.<\/b><\/p>\n

D’altra banda, l\u2019antiespumant <\/span>Emultrol DFM DV-1 S<\/b> mostra una capacitat de <\/span>mantenir un volum d’escuma de 50 ml i en la repetici\u00f3 de la prova passats 15 minuts aconsegueix mantenir l’escuma en 75 ml.<\/b><\/p>\n

Les proves tamb\u00e9 es van realitzar passada 1 hora, per\u00f2 cap antiespumant va ser capa\u00e7 de mantenir l’escuma controlada, per la qual cosa es dedueix que aquest va perdre el seu efecte.<\/span><\/p>\n

 <\/p>\n

Conclusions<\/b><\/p>\n

Es recomana l\u2019antiespumant <\/span>Emultrol DFM DV-1 S <\/b>no sols per mostrar un millor efecte immediat antiespumant respecte a l\u2019antiespumant refer\u00e8ncia del mercat, sin\u00f3 tamb\u00e9 per la seva <\/span>major estabilitat amb el temps en un mitj\u00e0 amb un pH alcal\u00ed com el del detergent per a rentavaixella.<\/b><\/p>\n

Estudi comparatiu d\u2019antiespumants per a suavitzant amb Emultrol DFM DV-30, Emultrol DFM DV-1 i una refer\u00e8ncia de la compet\u00e8ncia<\/b><\/p>\n

En el present estudi es <\/span>compara l’efectivitat antiespumant al llarg del temps dels antiespumants Emultrol DFM DV-30, Emultrol DFM DV-1 i un antiespumant de la compet\u00e8ncia.<\/b><\/p>\n

Comparant la composici\u00f3 de les refer\u00e8ncies d’aquest estudi, l\u2019antiespumant de la compet\u00e8ncia \u00e9s una emulsi\u00f3 aquosa de silicona i altres components amb una concentraci\u00f3 de s\u00f2lids del 30%.<\/span><\/p>\n

D’altra banda, les dues refer\u00e8ncies de Concentrol, que es comparen en aquest estudi estan basades en emulsions aquoses de silicona,<\/span> Emultrol DFM DV-30<\/b> i <\/span>Emultrol DFM DV-1,<\/b> que contenen: 30% i 17% de s\u00f2lids respectivament. La viscositat de les refer\u00e8ncies estudiades es mostren a continuaci\u00f3 en la Taula 1.<\/span><\/p>\n

 <\/p>\n

Per a la determinaci\u00f3 de l’efectivitat dels diferents antiespumants, es realitzen assajos de macroescuma, basats en el m\u00e8tode d’injecci\u00f3 de gas. S’utilitza com a mitj\u00e0 espumant una diluci\u00f3 aquosa amb un factor de 1\/5 de la base suavitzant neutra, sense antiespumants.<\/span><\/p>\n

 <\/p>\n

Metodologia<\/b><\/p>\n

Per al present estudi s’ha usat el m\u00e8tode d’injecci\u00f3 de gas. Primerament, es mesuren 200 ml de mitjana en un vas de precipitats de 1000 ml, en condicions de temperatura ambient 25 \u00b0C i agitaci\u00f3 magn\u00e8tica de 1000 rpm. Posteriorment, s’addiciona l\u2019antiespumant corresponent amb una dosi de 0,025%. Immediatament despr\u00e9s del dosatge de l\u2019antiespumant, s’injecta el gas mitjan\u00e7ant un difusor de gasos (pressi\u00f3: 1 kg\/cm\u00b2; cabal: 0,1 l\/min). A continuaci\u00f3 es mesura el volum de l’escuma formada, en intervals de 30 segons, durant 15 minuts.<\/span><\/p>\n

Gr\u00e0fic 1. Es compara el volum d’escuma format al llarg del temps amb antiespumants basats en emulsions de silicona amb diferent concentraci\u00f3 de s\u00f2lids, en una base suavitzant.<\/span><\/i><\/p>\n

\"\"<\/span><\/p>\n

Com es pot observar, la prova control mostra un r\u00e0pid increment del volum d’escuma, mentre que les proves amb els diferents antiespumants de silicona en emulsi\u00f3 aquosa s\u00f3n capa\u00e7os de mantenir <\/span>un nivell d’escuma sense grans difer\u00e8ncies en els primers 5 minuts.<\/b><\/p>\n

A llarg termini, les difer\u00e8ncies en el volum d’escuma generada s’accentuen, podent-se observar com el <\/span>Emultrol DFM DV-30<\/b> mant\u00e9 la millor efectivitat a llarg termini seguit de l\u2019antiespumant de la compet\u00e8ncia. Finalment l\u2019antiespumant <\/span>Emultrol DFM DV-1 <\/b>mostra una capacitat antiespumant molt eficient per la seva redu\u00efda quantitat de s\u00f2lids respecte a les altres refer\u00e8ncies comparades en aquest estudi.<\/span><\/p>\n

 <\/p>\n

Conclusi\u00f3<\/b><\/p>\n

En resum, l\u2019antiespumant <\/span>Emultrol DFM DV-30 <\/b>es mostra com el m\u00e9s efectiu, <\/span>en comparaci\u00f3 amb l\u2019antiespumant de la compet\u00e8ncia<\/b>, que cont\u00e9 una quantitat similar de s\u00f2lids. D’altra banda, la refer\u00e8ncia <\/span>Emultrol DFM DV-1<\/b> demostra ser l\u2019antiespumant m\u00e9s eficient per la seva \u00f2ptima relaci\u00f3 <\/span>d’efectivitat\/s\u00f2lids.<\/b><\/p>\n

Tal com hem pogut validar en els seg\u00fcents estudis, les refer\u00e8ncies Concentrol <\/span>Emultrol DFM DV-30 i Emultrol DFM DV-1<\/b> no sols s\u00f3n efectives al moment de la seva aplicaci\u00f3, sin\u00f3 que tamb\u00e9 ho s\u00f3n al cap d’un temps. \u00c9s a dir, continuen trencant l’espuma durant uns minuts, temps suficient per a poder realitzar un envasament efectiu.<\/b><\/p>\n

A Concentrol tenim clar que un dels punts forts del nostre ADN \u00e9s l’aposta pel coneixement. Gr\u00e0cies a la labor dels t\u00e8cnics de laboratori, podem realitzar constants comprovacions per a avaluar els resultats de les nostres refer\u00e8ncies. Aix\u00f2 ens permet oferir una bona qualitat-preu i resoldre les necessitats de tots els nostres clients de 82 pa\u00efsos i dels 5 continents.<\/span><\/p>\n
