DESCRIZIONE dell'invenzione industriale dal titolo: DESCRIPTION of the industrial invention entitled:
"Stoppino assorbente i liquidi per l'evaporazione di un liquido mediante calore" "Liquid absorbent wick for evaporation of a liquid by heat"
La presente invenzione si riferisce ad uno stoppino assorbente i liquidi per l’evaporazione di un liquido mediante calore. The present invention refers to a wick that absorbs liquids for the evaporation of a liquid by heat.
I metodi noti per l'evaporazione di un liquido mediante calore implicano l'impiego di uno stoppino, una porzione del quale viene impregnata in un liquido quale un pesticida, una fragranza o,simile. Dopo l'assorbimento dell'agente liquido, lo stoppino è riscaldato all'altra sua estremità per causare l'evaporazione del liquido. Known methods for evaporating a liquid by heat involve the use of a wick, a portion of which is soaked in a liquid such as a pesticide, fragrance or the like. After the absorption of the liquid agent, the wick is heated at its other end to cause evaporation of the liquid.
Tuttavia, è difficile preparare un liquido in modo consistente e continuo per un lungo periodo di tempo. E' pertanto desiderabile sviluppare uno stoppino assorbente i liquidi in grado di evaporare un liquido in modo consistente e continuo. La presente invenzione è diretta a risolvere i problemi sopra citati della tecnica nota. A tal scopo, l'invenzione fornisce uno stoppino assorbente i liquidi in grado di evaporare un liquido in modo consistente e continuo per un periodo di tempo molto più lungo grazie all’incorporazione nello stoppino di un resinato-modificato. However, it is difficult to consistently and continuously prepare a liquid over a long period of time. It is therefore desirable to develop a liquid absorbent wick capable of evaporating a liquid consistently and continuously. The present invention is aimed at solving the above mentioned problems of the known art. For this purpose, the invention provides a wick absorbing liquids capable of evaporating a liquid consistently and continuously for a much longer period of time thanks to the incorporation in the wick of a modified resin.
In altre parole, l'invenzione si riferisce ad uno stoppino assorbente i liquidi per l'evaporazione di un liquido mediante calore, caratterizzato dal fatto che un resinato modificato è incorporato nello stoppino. La via di evaporazione non è suscettibile di essere bloccata durante l'impiego dello stoppino secondo l'invenzione, pertanto, è possibile evaporare un liquido in modo consistente per un lungo periodo. In other words, the invention relates to a liquid absorbing wick for evaporating a liquid by heat, characterized in that a modified resin is incorporated in the wick. The evaporation path is not capable of being blocked during the use of the wick according to the invention, therefore, it is possible to evaporate a liquid consistently for a long period.
Il resinato modificato della presente invenzione è un prodotto ottenuto mediante distillazione di una resina naturale generata sul tronco di alberi di pino appartenenti alla famiglia delle Pinaceae del genere Pinus per rimuovere l'olio di trementina. E' un acido resinico comprendente acido abietico, acido neoabietico, acido diidroabietico, acido tetraidroabietico, acido deidroabietico, acido pimarico, acido isopimarico, acido levo-pimarico ecc. come componenti principali. The modified resin of the present invention is a product obtained by distillation of a natural resin generated on the trunk of pine trees belonging to the Pinaceae family of the genus Pinus to remove the oil of turpentine. It is a resin acid comprising abietic acid, neoabietic acid, dihydroabietic acid, tetrahydroabietic acid, dehydroabietic acid, pimaric acid, isopimaric acid, levo-pimaric acid, etc. as main components.

Prova esempio 1 Try Example 1
Una soluzione di idrocarburo nom ai paraffinico contenente 0,667% (peso/volume) di pralletrina è versata in una bottiglia di evaporazione mediante riscaldamento. Gli stoppini assorbenti i liquidi preparati nell'esempio di preparazione 1 e nell'esempio di preparazione comparativo 1 sono stati rispettivamente associati al tappo della bottiglia e poi applicati al dispositivo di evaporazione termica, come illustrato in figura 1. L'evaporazione termica è effettuata innalzando la temperatura superficiale dell'elemento riscaldante a 120°C. Sono state misurate la capacità di evaporazione della pralletrina e dell'agente liquido entro un periodo di tempo di due ore, dalla quarta alla sesta -ora e dall'ora 104esima all'ora 106esima dall'inizio del riscaldamento, rispettivamente. La capacità di evaporazione della pralletrina è determinata mediante il calcolo basato sui risultati misurati con un'apparecchiatura di gas cromatografia sugli estratti in acetone che costituisce il materiale evaporato trattenuto da un gel di silice. La capacità di evaporazione dell'agente liquido è determinata osservando la riduzione di liquido nella bottiglia. I risultati sono illustrati nella tabella 2 che segue. A nominal paraffinic hydrocarbon solution containing 0.667% (w / v) of prallethrin is poured into an evaporation bottle by heating. The wicks absorbing the liquids prepared in the example of preparation 1 and in the example of comparative preparation 1 were respectively associated with the bottle cap and then applied to the thermal evaporation device, as illustrated in figure 1. The thermal evaporation is carried out by raising the surface temperature of the heating element at 120 ° C. The evaporation capacity of the prallethrin and the liquid agent were measured within a time period of two hours, from the fourth to the sixth hour and from the 104th hour to the 106th hour from the start of heating, respectively. The evaporation capacity of the prallethrin is determined by calculation based on the results measured with a gas chromatography apparatus on the acetone extracts which constitutes the evaporated material retained by a silica gel. The evaporation capacity of the liquid agent is determined by observing the reduction of liquid in the bottle. The results are shown in Table 2 below.
Tabella 2 Table 2
Così utilizzando lo stoppino assorbente i liquidi della presente invenzione, l'agente liquido e il componente attivo ivi presente possono essere evaporati in modo consistente. Thus by using the liquid absorbent wick of the present invention, the liquid agent and the active component present therein can be consistently evaporated.
