Description
Foreliggende oppfinnelse vedrører en fremgangsmåte ved fremstilling av et fibermateriale belagt med atomiserte partikler av aktivt karbon. Et slikt materiale brukes som absorbsjonsmateriale, f.eks. i gassmasker, beskyttelsesbekledning, kasting av avfall og fremfor alt i bandasjer. Som en bestandddel i bandasjer absorberer materialet bakterier og lukt fra infiserte sår og bidrar til en rask heling av såret. The present invention relates to a method for producing a fiber material coated with atomized particles of activated carbon. Such a material is used as absorption material, e.g. in gas masks, protective clothing, disposal of waste and above all in bandages. As an ingredient in bandages, the material absorbs bacteria and odors from infected wounds and contributes to the rapid healing of the wound.
Aktivt karbon er velkjent som absorbsjonsmateriale, og det er lenge brukt i mange forskjellige forbindelser. I visse forbindelser er det imidlertid en fordel om det aktive karbon kunne foreligge i arkform. Det er tidligere foreslått å fremstille slik arkform. Et forslag ligger i at et normalt rayonstoff utsettes for en atmosfære av karbondioksyd ved en høyere tempera-tur på ca. 300°C, hvoretter en delvis karbonisering av stoffet frembringes ved å oppvarme til ca. 900°C. Denne metoden er imidlertid tidkrevende og dyr, og de resulterende egenskapene til materialet tilfredsstilte ikke forventningene. Activated carbon is well known as an absorbent material, and it has long been used in many different compounds. In certain compounds, however, it is an advantage if the active carbon could be present in sheet form. It has previously been proposed to produce such a sheet form. One suggestion is that a normal rayon fabric is exposed to an atmosphere of carbon dioxide at a higher temperature of approx. 300°C, after which a partial carbonization of the substance is produced by heating to approx. 900°C. However, this method is time-consuming and expensive, and the resulting properties of the material did not meet expectations.
Videre har det vært foreslått å fremstille et fibermateriale belagt med aktivt karbon ved en fremgangsmåte i vandig løsning. Som fibermateriale har det vært brukt bomull og asbest, som ble sprengt i vann og som ble tilsatt atomisert karbon under sterk røring. Furthermore, it has been proposed to produce a fiber material coated with activated carbon by a method in aqueous solution. As fiber material, cotton and asbestos have been used, which were blasted in water and atomized carbon was added under vigorous stirring.
Problemet har imidlertid vært å få karbonpartiklene til å hefte til fibrene. Det ble prøvet å løse dette problem ved å tilsette visse bindemidler til den vandige løsning. Virkningen av bindemidlet er imidlertid lav, og samtidig påvirkes materialets egenskaper i negativ retning. The problem, however, has been getting the carbon particles to adhere to the fibers. An attempt was made to solve this problem by adding certain binders to the aqueous solution. However, the effect of the binder is low, and at the same time the material's properties are affected in a negative direction.
Dette problemet løses ved foreliggende oppfinnelse på en enkel og effektiv måte. This problem is solved by the present invention in a simple and effective way.
Ifølge oppfinnelsen bringes det atomiserte aktive karbon på et fibermateriale i vandig suspensjon ved å tilsette suspensjonen et tensid. According to the invention, the atomized active carbon on a fiber material is brought into aqueous suspension by adding a surfactant to the suspension.
Ifølge en spesielt viktig utførelsesform av fremgangsmåten ifølge oppfinnelsen produseres aktivt karbon i arkform ved at det atomiserte karbon bringes på cellulosefibre i suspensjon, og at arkene deretter formes av suspensjonen. According to a particularly important embodiment of the method according to the invention, active carbon is produced in sheet form by placing the atomized carbon on cellulose fibers in suspension, and the sheets then being formed from the suspension.
Mengden av karbon i karbon-cellulosemasseblandingen er 1-65%. The amount of carbon in the carbon-cellulose pulp mixture is 1-65%.
Mengden av tilsatt tensid bør være slik at tensidkonsentra-sjonen i fibersuspensjonen er IO-<7>- 10-<1>%. The amount of surfactant added should be such that the surfactant concentration in the fiber suspension is 10-<7>- 10-<1>%.
Egnede tensider har vist seg å være kvarternære ammonium-forbindelser basert på dinonylfenol, for eksempel Berocell 564. Suitable surfactants have been found to be quaternary ammonium compounds based on dinonylphenol, for example Berocell 564.
For måling av absorbsjonen til materialet som fremstilles, ble en absorbsjonsprøve med metylenblått anvendt. For measuring the absorption of the material being produced, an absorption test with methylene blue was used.
En bestemt mengde av materialet ble rystet i en løsning av metylenblått, materialet ble filtrert fra, og fargedybden til løsningen ble målt i et spektrofotometer. A certain amount of the material was shaken in a solution of methylene blue, the material was filtered off, and the color depth of the solution was measured in a spectrophotometer.
Ved eksperimenter for fremstillingen av cellulosefibre belagt med aktivt karbon ble forskjellige massetyper brukt, så som ubleket furusulfatmasse, bleket furusulfatmasse, bleket bjerkesulfatmasse og kjemisk-mekanisk masse, såkalt CIMP. Fra de forskjellige massetyper ble en suspensjon med en konsentrasjon på 3 g pr. liter fremstilt. Den ønskede karbonmengde ble satt til 1 liter av den aktuelle suspensjon. Massesuspensjonen ble tilsatt et kationisk tensid i en mengde på 0,02 ml/g masse. Etter omhyggelig røring som førte til sikker fukting av alt karbon, ble blandingen støpt i arkform. Etter støpingen ble arket presset og tørket på en roterende tørker ved 60°C i 2 timer. De oppnådde resultater er vist i tabellen nedenfor. In experiments for the production of cellulose fibers coated with activated carbon, different pulp types were used, such as unbleached pine sulphate pulp, bleached pine sulphate pulp, bleached birch sulphate pulp and chemical-mechanical pulp, so-called CIMP. From the different pulp types, a suspension with a concentration of 3 g per liters produced. The desired amount of carbon was added to 1 liter of the relevant suspension. A cationic surfactant was added to the pulp suspension in an amount of 0.02 ml/g pulp. After careful stirring which led to the sure wetting of all the carbon, the mixture was cast into sheet form. After casting, the sheet was pressed and dried on a rotary dryer at 60°C for 2 hours. The results obtained are shown in the table below.
Som det fremgår av resultatene, er det mulig å lage ark av karbon og cellulosemasse med god retensjon av karbon og uten at karbonets absorbsjonskapasitet nedsettes. As can be seen from the results, it is possible to make sheets of carbon and cellulose pulp with good retention of carbon and without reducing the absorption capacity of the carbon.
Oppfinnelsen er ikke begrenset til de beskrevne utførelses-former, men kan varieres innenfor omfanget av den oppfinneriske idé. The invention is not limited to the described embodiments, but can be varied within the scope of the inventive idea.
