Description
Technical Field
The invention relates to a Plamsa-based straw fiber treatment process for an artificial board, and belongs to the technical field of straw artificial board processing methods.
Background
Compared with wood, the straws of wheat, rice and the like have high sugar content and smooth appearance, the surface horniness layer blocks wetting, diffusion and permeation of glue drops, the existence of the outer layer of the straws has great adverse effect on the bonding property of the artificial straw board, and the mechanical strength and the internal bonding force of the artificial straw board can be reduced.
And a large amount of ions, excited molecules, free radicals and other active particles in the PLASMA PLASMA are used for purely physical impact, atoms on the surface of the straw material or atoms attached to the surface can be knocked off, original pollutants and impurities on the surface of the material are removed, an etching effect is generated, the surface of the material is roughened, a plurality of fine pits and ravines are formed, the specific surface area of the surface of the material is increased, and the wettability of the surface of the material can be improved.
Disclosure of Invention
In view of the above technical problems, the present invention aims to: provides a Plamsa-based straw fiber treatment process for artificial boards.
The technical scheme of the invention is realized as follows: a Plamsa-based straw fiber treatment process for artificial boards comprises the following steps:
(1) putting straw raw materials into a Plamsa vacuum plasma treatment instrument;
(2) treating at low power of 150-200W for 1-5 min to make C2 (hydroxyl) appear on the surface of the straw;
(3) treating at high power of 400-500W for 30-60 min to make C3 (carbonyl) and C4 (carboxyl) appear on the surface of the straw;
(4) taking out the treated straws for later use.
Preferably, after the step (2) is finished, waiting for 1min-5min, and then entering the step (3).
Due to the application of the technical scheme, compared with the prior art, the invention has the following advantages:
according to the method, the straw fibers are treated by using the Plamsa with different powers, and the C spectral peak analysis shows that the oxidation of carbon on the surfaces of the straw fibers depends on the Plamsa treatment power, and the content and the change of functional groups on the surfaces of the straw fibers treated by the Plamsa are different along with the different Plamsa treatment powers; c2 The (hydroxyl) is generally considered to be the characteristic absorption of the hydroxyl, the increase of the content means that the hydroxyl content on the surface of the straw fiber is increased, the wettability of the surface of the straw fiber is inevitably increased, the C2 is obviously increased after being treated for 1min at a lower (200W) power, and the C3 (carbonyl) and the C4 (carboxyl) are sequentially appeared along with the time extension at a high power of 400W, but the C2 (hydroxyl) is sharply reduced.
As the six-membered ring in the chemical structure of the straw fiber is a relatively stable structural unit, tests show that under a high-energy environment, the six-membered ring can be deeply oxidized to form the fusidic acid or be broken to form a low-molecular compound, and the low-molecular compound can also be oxidized to form the fusidic acid, so that the C4 (carboxyl) content is generated after high-power or long-time treatment. In the Plamsa treatment, the surface of the straw is oxidized, the hydroxyl content is increased, the wettability of the surface of the straw fiber is increased, the stable structure of a six-membered ring in the chemical structure of the straw fiber is also damaged, low molecular compounds are formed, more carbonyl groups and carboxyl groups are generated, the bonding and the combination of the straw fiber and the inorganic gel are more facilitated, and the inorganic gel straw plate with higher static bending strength and internal bonding force can be produced.
Detailed Description
In order to make the technical problems solved, technical solutions adopted, and technical effects achieved by the present invention clearer, the technical solutions of the embodiments of the present invention will be described in further detail below, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Example 1
The invention relates to a Plamsa-based straw fiber treatment process for an artificial board, which comprises the following steps of:
(1) putting the straw raw material into a Plamsa vacuum plasma treatment instrument;
(2) treating at low power of 150W for 1min to make C2 (hydroxyl) appear on the surface of the straw;
(3) treating for 30min under high power of 400W to enable C3 (carbonyl) and C4 (carboxyl) to appear on the surface of the straw;
(4) taking out the treated straws for later use.
Example 2
(1) Putting straw raw materials into a Plamsa vacuum plasma treatment instrument;
(2) treating at low power of 180W for 3min to make C2 (hydroxyl) appear on the surface of the straw, and then waiting for 2min to stabilize the material;
(3) processing for 50min under high power of 450W to enable C3 (carbonyl) and C4 (carboxyl) to appear on the surface of the straw;
(4) taking out the treated straws for later use.
Example 3
(1) Putting the straw raw material into a Plamsa vacuum plasma treatment instrument;
(2) treating at low power of 200W for 4min to make C2 (hydroxyl) appear on the surface of the straw, and then waiting for 3min to stabilize the material;
(3) treating at high power of 500W for 55min to make C3 (carbonyl) and C4 (carboxyl) appear on the surface of the straw;
(4) taking out the treated straws for later use.
In the process, after the straw fiber is treated for 1min under low power, the hydroxyl is obviously increased, carbonyl and carboxyl appear sequentially along with time extension under high power, and as a six-membered ring in the chemical structure of the straw fiber is a relatively stable structural unit, tests show that under a high-energy environment, the six-membered ring can be deeply oxidized to form the fusidic acid or be broken to form a low-molecular compound, and the low-molecular compound can also be oxidized to form the fusidic acid, so that the carboxyl content is generated after the high-power or long-time treatment.
Wherein, the straw can be wheat straw or straw of other plants.
As can be seen from the following table, the artificial board made of the straw fiber treated by the method has more excellent performance, and all indexes of the artificial board are superior to those of the common straw artificial board.
