Description
Technical Field
The invention belongs to the technical field of agricultural straw processing and recycling and agricultural, horticultural and forestry seedling raising and planting containers, and particularly relates to a material treatment process capable of enhancing toughness and moisture resistance of a straw container.
Background
In 2006, a patent "production method of straw water storage seedling raising pot" (ZL 03138791.8) disclosed in chinese patent, which takes plant straws as raw materials to synthesize the straw seedling raising pot, and claims: (1) drying and crushing the straws into particles with the particle size of less than 1.5mm during straw processing; (2) polyacrylamide is used as an adhesive, is diluted by water according to the proportion of 1 to 200-700, straw is mixed with 0.4-1 unit of polyacrylamide according to the proportion of 100 unit of dry weight, then straw raw materials and diluted adhesive liquid are mixed and stirred uniformly, and the mixture is placed into a forming machine and then is pressed by 10-70kg for molding.
The invention of this patent has been used for the past 20 years, and in the course of the last 20 years, experience is accumulating and technology is advancing. Several related patents on molding methods and molding apparatus have also been invented around this patent. For the seedling pot of straw, it is the biggest advantage that it is decomposable and pollution-free, raw materials source is constantly its biggest, but find in the production and processing course, the patent technology that uses Chinese patent (ZL 03138791.8) to disclose the method that the particle diameter is smaller than 1.5mm to process the straw raw materials under the dry condition has the drawback: firstly, dust, fire and the like are easily caused by drying and processing the straws, so that not only can the straw raw materials be lost, but also the air can be polluted, and the straw drying and processing method is also unfavorable for the health of processing personnel; secondly, the finer the particles are, the more energy and time are consumed, and the higher the cost is.
In view of these problems, we have made a number of attempts in practice to propose a more practical and improved method.
Disclosure of Invention
The invention aims to solve the problems in the prior art, and provides a material treatment process capable of enhancing the toughness and the water erosion resistance of a straw container.
The technical scheme adopted by the invention for solving the technical problems is as follows:
a material treatment process capable of enhancing the toughness and the water erosion resistance of a straw container is characterized by comprising the following steps of: the method comprises the following steps:
step one, processing straw fiber in a filamentous manner: firstly, placing straws in a piling pit, piling while fully sprinkling water on the surfaces of the straws, so that the straws slowly heat and ferment in the piling pit, softening the surfaces of the straws, processing the straws by using a straw rubbing and shredding grinder after 10 to 30 days of piling, processing the straws into the straws with the proportion of not less than 40 percent into filaments, and continuously keeping a wet state, wherein the wet state can feel wet when being touched by hands, but does not form water drops, and the straws can be used after being piled and heated for 3 to 10 days; the stacking time is prolonged, the container is excessively heated and needs to be turned over for heat dissipation, and the fiber strength is prevented from being influenced by excessive fermentation; the straw comprises: corn stover, wheat straw, sorghum stover, millet straw and rice straw;
secondly, adding sodium bentonite filler: 10-20% of bentonite is added according to the material state, when the material has higher phloem content, less wood content and better filamentation state, the addition amount of the bentonite can be properly reduced, otherwise, the addition amount of the bentonite is properly increased; the sodium bentonite filler can also be replaced by clay, kaolin or other types of bentonite, but the sodium bentonite is better, and the clay comprises red clay or yellow clay; after the straw is processed into wet filament fiber from dry fine particle, the fiber length and thickness of the material are increased, the specific surface area is relatively reduced, the attachment surface of the adhesive is reduced, and the water erosion resistance of the adhesive is affected. When the proportion of the bentonite is insufficient, the unsmooth strength of the surface of the straw container after molding is insufficient, and when the addition amount of the bentonite is too large, the molding and demolding difficulty is large, and small cracks are easy to crack on the surface of a finished product. The bentonite is added in a proper amount, so that the forming and demolding are easy, the surface of a finished product is smooth, and the finished product is small in deformation, beautiful and elegant after being dried;
step three, pressurizing and stirring: feeding the materials processed in the second step into a spiral stirrer for pressurizing and stirring; namely: the material is extruded from a hole under a certain pressure.
Compared with the prior art, the invention has the following beneficial effects:
according to the invention, sodium bentonite filler is added in the step 2, and the bentonite is added in a proper amount, so that the forming and demolding are easy, the surface of a finished product is smooth, and the finished product is small in deformation and beautiful and elegant after drying; step 3, pressurizing and stirring, so that the more the filamentous fibers are deformed, the smaller the expansion deformation of the formed straw fibers is, and the better the quality of a finished product is; the toughness and the water erosion resistance of the straw container are enhanced, and the high-quality straw container can be produced by adopting the materials processed by the method.
The technical scheme achieves the expected effect through tests, and the specific test process is as follows:
in 3 months 2021, 60 straw seedling raising rods trial-produced by the innovative technical scheme are adopted, each straw seedling raising rod is 400mm long and 150mm thick, and is transported to the rubber institute of academy of agriculture and sciences (located in delirium) in the tropical zone of China in Hainan for testing, logistics delivery is adopted, the mileage reaches 2460KKm, and no damage is caused.
26 days at 4 months in 2022, adopting 1000 seedling pots trial-produced by the innovative technical scheme to transport to a dry land agriculture and forestry research institute of Liaoning province for testing, adopting automobile transportation, and achieving 1000Km without damage of the seedling pots;
in 9 months at 2022, 1000 straw containers (the caliber is 240mm and the height is 200 mm) trial-manufactured by adopting the innovative technical scheme are transported to Atlanta maydis Fuxing technology Limited company in Sichuan for testing, and the mileage reaches 1400Km by adopting automobile transportation, so that no damage is caused.
10000 straw seedling pots produced by adopting the prior art are transported from the city to the Sichuan academy of agricultural sciences, logistics delivery is adopted, the mileage is 1400Km, and the result damage rate reaches nearly 40% after the straws are delivered to the city.
In 4 months in 2022, 200 straw containers produced by the innovative method are subjected to a water erosion resistance test, and 100 straw containers produced by the prior art are used as a reference, and the specific method is that the straw containers are placed in a plastic water tank, water is added into the water tank until the depth reaches 3-5cm, so that the bottom of the container is soaked in the water layer for a long time of 3-5cm, and the time reaches two months. During the process, grapes, shinyleaf yellowhorn and amorpha fruticosa cuttings are cut in the container, and the upper portion of the container is covered by a shed film to prevent moisture loss. Water was added to the tank 1 time a week to maintain the container humidity. Straw display:
* In a soaking experiment for two months, only 1 straw container produced by the innovative method is incompletely damaged, and the damage rate is 0.5%. While the control had 64 complete failures and 13 incomplete failures, the failure rate was 77%. The difference is quite obvious.
The full damage means that the bottle cannot be used at all, and the incomplete damage means that the bottle can be used even though the bottle is damaged.
