Abstract
The invention discloses a sorghum straw plate for a construction site fence. The sorghum straw plate comprises a sorghum straw, a binding agent and a functional additive, and is characterized in that the properly crushed sorghum straw with the conventional binding agent sprayed thereon and the functional additive is directly spread, rolled and formed through edge sawing. The sorghum straw is a natural-dried raw material. The sorghum straw raw material with low cost can provide the cheap and fine fence to increasingly construction sites; and the cheap and fine fence can be provided through a simple mode of reducing four production procedures. Under the condition of solving the straw burning prohibition problem (prohibition of the burning by the state), the sorghum straw is firstly applied to the construction site fence with wide demands; and as the use period of many construction site fences is generally shorter, a conventional construction site fence is excessively underemployed or excessively wasted, or causes higher use cost. The distinctive sorghum straw plate minimizes the use cost under the condition of guaranteeing the use quality.
Description
Technical field
The present invention relates to a kind of building site enclosing plate, is related specifically to a kind of sorghum stalk plate for building site enclosing.
Background technology
Chinese since the eighties in 20th century, grain yield is greatly improved, and straw quantity is also more, in addition the popularization of firewood-saving and coal-saving technology, burns coal and the popularization using liquefied gas, has straws more than needed in a large number in making rural area.Straw is made compost outer except packing ring, pasture is used on a small quantity, partly for heap, and major part is all burnt as fuel.
《The Law of the People's Republic of China on the Prevention and Control of Atmospheric Pollution》41st article of second item：Around congregated district of population, airport, near the main line of communication and in the region of local people's government's delimitation, open incineration straw, fallen leaves etc. produce the material of smoke contamination, and by location, competent administrative department for environmental protection of local people's governments at or above the county level orders to stop irregularities；It is cases of gross violation, less than 200 yuan can be located and imposed a fine, be caused significant damage and loss, undertake administrative and criminal penalty responsibility.
The problem that presently, there are is：In country, the smog of visible combustion straw is in slowly ascension repeatedly.
Prohibit and burn straw, why prohibit and more than, even remain incessant after repeated prohibitionTrace it to its cause and be：It is that the straw for staying in field have impact on sowing first, is unfavorable for crop growth.For peasant, " three summer jobs " are a seasons for rushed planting, and the behavior in any impact farming season all allows people distressed.And existing straw processing mode is time-consuming bothersome, to not only put together, also want bundling, entrucking, transport, the money that straw is cashed in the end does not even get at construction site and does a work of nature.Next to that there is most of peasant to think all so to burn for generations, moreover it is possible to strengthen the fertility in soil.3rd be straw recycling it is not smooth.Straw is high-grade fuel, fertilizer, feedstuff in the past, and now with rate is low, deficiency in economic performance, it is most economical labour-saving way to burn.
How to solve the problems, such as that straw prohibits burning actuallyObviously, the development of low-carbon economy is trend and certainty, and crop straw burning is not only an agricultural problem, forbids of course not fundamental policy by regulation order merely.Treating both the principal and secondary aspects of a disease is wanted, stifled dredging is developed simultaneously.
The current comprehensive utilization of straw is：
1st, Mechanized Straw also field：The method of straw-returning has two kinds：One is smashed straw with machinery, ploughs deeply and sternly bury during farming, is decomposed straw corruption using the microorganism in soil.Another kind of straw return field effective ways be by crushed stalk after, be doped into appropriate Calx and human and animal excreta, allow which to ferment, in the environment of semi-oxidized semi-reduction go bad rot, further take out and use as fertilizer also field.
2nd, cross abdomen also field：It is, by technical finesses such as ensiling, microbial, ammonification, thermal jets, can effectively to change the organizational structure of straw by straw to cross abdomen also field, makes straw become the high-quality feed for being easy to that domestic animal digests, mouthfeel is good.
3rd, cultivate edible fungi：After by crushed stalk, make edible fungus cultivation matrix with other dispensing scientific matchings, the edible fungi such as Auricularia, mushroom, Tremella can be cultivated, the contradiction insufficient with cotton seed hullss of Edible Fungi fast development in recent years can be efficiently solved.The base material after bacterium is educated Jing after processing, still as feed stripped or can make fertilizer also field.
4th, Biogas：Sorghum stalk straw etc. belongs to organic substance, is the good material of Biogas.The northern, southern of China can be utilized, especially southern area, and temperature is high, and the season using biogas is long.The method that Biogas can adopt anaerobic fermentation.The method is that planting industry, aquaculture and methane-generating pit combine, and the biogas produced using straw is cooked and illuminated, biogas residue pig feeding, and pig manure and biogas slurry are used as fertilizer also field.This kind of mode is the eucyclic good model of the ecological agriculture, and it has adapted to the demand of modern countryside development, is welcomed warmly by mass peasants.
5th, as the raw material of industry：Agricultural crop straw can be used as the raw material of papermaking, be also used as compressed fibre timber, can overcome the disadvantages that the deficiency of timber resources, reduce the cutting capacity of timber, improves afforestation rate, makes ecological environment to benign development.
The content of the invention
The purpose of the present invention is to propose to a kind of sorghum stalk plate for building site enclosing, solves the problems, such as the burning of straw by formula comprehensive utilization of rising in value.
Urban architecture building site periphery is covered, shelter.A kind of beautification is played, neatly, unified effect.Now in basic urban construction, can all be used for.The height of enclosing common are 2 meters typically more than 2 meters, 4 meters, 6 meters and 8 meters, or higher 12 meters etc., enclosing surface and put up design sketch and publicity picture of the project etc..Or it is used for Public Welfare advertisement.
As the use of many building site enclosings is all provisional, thus is seemed using conventional building site enclosing and excessively waste one's talent on a petty job or excessively waste.In other words, use cost is too high.The present invention releases a kind of distinguished sorghum stalk plate for this, and use cost minimum is made every effort in the case where use quality is guaranteed.
Conventional sorghum stalk plate is using a kind of artificial composite board of function admirable made by agricultural production residue-sorghum stalk.Sorghum stalk plate is between medium density fibre board (MDF) and wooden flake board in aspect of performance, it is a kind of homogeneous sheet material as medium-density plate, and the surface with unusual light, its production cost is also lower than particieboard, and in intensity, dimensional stability, machining property, screw and nail holding ability, water resistance, veneer performance and density, (aspect such as light 20%) all surpasses wooden flake board for it.Its formaldehydeless release, thus it is free from environmental pollution.Its wood raw material not against worsening shortages, and the use of annual all renewable cheap and inexhaustible sorghum stalk is raw material, Gu and building and the furniture industry demand growing to it can be met.Technical requirements：The characteristics of formaldehydeless release of sorghum stalk plate, water resistance are good, profile density is uniform and have cycling processability good, its conventional mechanical property is also very excellent in addition.Sorghum rod plate and water suction thickness expansion rate (%) 3.3 vertical 1,000 1400 free formaldehyde release (mg/100g) of plate face nail-holding ability (N), 30 ≈ 0 of 15 30.0 internal bond strength (Mpa) of particleboard production comparison test project particieboard sorghum stalk plate density (g/cm3) 0.60 moisture content (%), 6.0 MOR (Mpa) 0.30 0.60.
