Abstract
Przedmiotem zgłoszenia jest sposób wytwarzania skrobi termoplastycznej ze skrobi natywnych, który charakteryzuje się tym, że od 30% masowych do 60% masowych natywnej skrobi kukurydzianej, albo natywnej skrobi kukurydzianej woskowej, albo natywnej skrobi ziemniaczanej miesza się w obecności 5% masowych roztworu 10% kwasu octowego oraz przy dodatku plastyfikatora, który stanowi od 10% masowych do 20% masowych gliceryny i od 25% masowych do 45% masowych ustabilizowanych komunalnych osadów ściekowych, po czym mieszaninę zagęszcza się do momentu powstania zwartych granul i wytłacza. Zgłoszenie obejmuje też skrobię termoplastyczną powstałą ze skrobi natywnych, zwłaszcza do zastosowań technicznych, która charakteryzuje się tym, że zawiera od 30% masowych do 60% masowych natywnej skrobi kukurydzianej, albo natywnej skrobi kukurydzianej woskowej, albo natywnej skrobi ziemniaczanej, od 25% masowych do 45% masowych ustabilizowanych komunalnych osadów ściekowych, od 10% masowych do 20% masowych gliceryny i 5% masowych roztworu 10% kwasu octowego.The subject of the application is a method for the production of thermoplastic starch from native starches, which is characterized in that from 30% by weight to 60% by weight of native maize starch or native waxy maize starch or native potato starch is mixed in the presence of a 5% by mass solution of 10% acid. vinegar and with the addition of a plasticizer, which constitutes from 10% by mass to 20% by mass of glycerin and from 25% by mass to 45% by mass of stabilized municipal sewage sludge, and then the mixture is thickened until compact granules are formed and extruded. The application also covers a thermoplastic starch derived from native starches, especially for technical applications, which is characterized in that it contains from 30 wt.% To 60 wt.% Native maize starch, or native waxy maize starch, or native potato starch, from 25 wt.% To 45% by mass of stabilized municipal sewage sludge, from 10% by mass to 20% by mass of glycerin and 5% by mass of a solution of 10% acetic acid.
