TH96989A - Process for preparing plant leaves for coating foam containers and starch with such substances. - Google Patents

Abstract

DC60 (30/12/48) has revealed the invention of compostable starch foam compositions coated with plant leaves. Plant leaves were boiled in alkaline solution resulting from the use of KOH, NaOH, 0.1-25% by weight by volume in ratio 1 1 or water ashes. The pH was measured in the range of 7.5-14 for 30 minutes to 2 hours at a temperature of 100 degrees Celsius, pressure 1 atmosphere. Then come to wash the water thoroughly Bring litmus paper The plant leaves were tested to have a pH in the range of 5 to 7, then immersed in a solution with 1.5-3% Active Cl chloride at a ratio of 100 ml per plant leaf at 15% Consistency. 1 liter for 2-3 hours, washed with clean water until the smell is lost Or bring to a boil with 5-15% sodium silicate per 20 kg of wet plant leaves and 5-15% hydrogen peroxide, both for 2-3 hours and warmed to about 50-100 degrees Celsius. The leaves are washed with water until clean. The prepared leaves are used as appropriate, the plant leaves that have been dried are dried and then coated. Pour the flour that has been mixed well. Or injection into mold The processed leaves are then placed on The dough mixture is then closed with compression pressure. (Compression) Female mold between 0.5 to 5 tons at a temperature range of 100 to 400 degrees Celsius for 1-10 minutes. Open the mold, put the workpiece into the oven at 60 to 100 degrees Celsius for 10 to 60 minutes before being removed at temperature. room The composition of powdery foam coated with compostable plant leaves. And this production process is suitable for making a product for consumption and consumption. To replace existing plastics and foam, PS is difficult to degrade over time.
