preparation example Construction

[0050] A method of preparing a degradable sugar caneseed film comprises:

[0051] According to the weight of the weight, 4-6 parts of the cassava starch was dissolved in 88-92 parts of water, stirred at a temperature of 88-92 ° C, so that the tapacoca starch was passed;

[0052] After the oxa starch is paste, add 0.5-2.5 parts of the weight of the weight of the weight of the slumper ultra-fine powder, stir;

[0053] After the sugar caneseed ultrafine powder is stirred, it is added to 2-4 parts of glycerol and 0.4-0.6 parts of alginate, stirred at a temperature of 78-82 ° C, and dissolve glycerol and alginate;

[0054] After solubilizing the sodium alginate, the ultrasound treatment was carried out 40-50 min to give colloidal fluid;

[0055] The colloidal fluid is processed into a degradable sugar caneseed film.

[0056] The sugar caneseed ultrafine powder is stirred together with the ultrasonic treatment and the gelatinous tapacoca starch, which can make the sugar canesess ultrafi...

Abstract

A degradable bagasse mulch film and a preparation method thereof. Including: according to parts by weight, 4-6 parts of tapioca starch are dissolved in 88-92 parts of water, stirred at a temperature of 88-92°C to gelatinize the tapioca starch; after the tapioca starch is gelatinized, add The bagasse superfine powder of 0.5-2.5 parts in parts by weight stirs; after the bagasse superfine powder is fully stirred, add 2-4 parts of glycerol and 0.4-0.6 parts of sodium alginate in parts by weight, Stir at a temperature of 78-82°C to dissolve the glycerin and sodium alginate; after the glycerin and sodium alginate are fully dissolved, perform ultrasonic treatment for 40-50 minutes to obtain a colloidal solution; process the colloidal solution into a degradable bagasse mulch. The degradable bagasse mulch film and the preparation method thereof can realize the direct utilization of bagasse and promote the extensive utilization of biomass resources.

Description

Technical field [0001] The present invention relates to a field of floral production, and more particularly to a degradable sugar caneseed floral film and a preparation method thereof. Background technique [0002] Sugar canesets belong to non-wood fibers, which can be included in the scope of grass fibers. It has a very thin P layer (primary wall), a thicker S1 layer (secondary wall outer layer) and a S2 layer (secondary wall) divided into two major layers. The microfiber arrangement and axial direction of the S2 layer is about 30-40 °, and the microfiber is from about The basic microfiber is composed. However, it is different from the general historical fibers, with a source of production, huge output, simple collection, small transport radius, is a very high quality renewable agricultural waste resource. For a long time, the comprehensive utilization rate and the resulting added value of sugar canesets have been low, most of which are burned off or directly discarded as energ...
