Stacking and aminating method is a method of stacking straws into straws and sealing them with a plastic film for ammoniating straws. It is also known as stacking method and picking method. Seasonal and weather choices, preparation of raw materials, and materials are basically the same as the pitting ammoniation method. The difference is that there is no need for a cement pit or crypt, which can be done on flat ground. Stacking method operating procedures see the relevant article, here will briefly describe the main points. (1) Operation steps On the dry and flat ground, 0.1-0.2 mm thick non-toxic polyethylene plastic film was spread, and the straw was stacked neatly and neatly. The use of urea or ammonium bicarbonate as an ammonia source for the treatment of straw is generally performed by depositing an ammonia source along the side of the stack. The source of ammonia can be dissolved in water and sprinkled with urea or ammonium bicarbonate. If treated with ammonia water, it can be poured to the top and then poured; with ammonia ammoxidation, ammonia is injected with special equipment after stacking and sealing. The size of yours depends on your situation. Daqi is suitable for ammoniation of liquid ammonia, it can save plastic film, and it is easy to mechanize management. However, water is not easy to spray evenly, and it is easy to leak gas: Specifications are generally 4.6 meters long and 6 meters high and 4.6 meters long. In order to facilitate ammonia, a porous plastic tube or hose can be buried in the middle of the crucible. Small oysters are suitable for urea or ammonium bicarbonate, specifications are generally 2 meters long and 2 meters wide and 1.5 meters. Grasshoppers can also be made into cones. Regardless of that specification, the dome should be made of a ridge type to facilitate the draining of rainwater. The plastic sheeting of the lower storehouse and the upper cover is set at 1 meter on each side so that the plastic film on both sides can be folded and compacted with mud and sealed without leakage. If liquid ammonia amination is used, ammonia is injected after the stacking is completed. Connect the hard plastic tube to the liquid ammonia tube or ammonia bottle and feed ammonia gas at 3% of the dry weight of the straw. At present, there are two types of ammonia used in our country: one is ammonia tank trucks directly from the fertiliser plant to ammonia on the site, and the other is ammonia in the ammonia tanker. Apply ammonia to the straw again. (2) Notes on heap amination 1 The choice of plastic film used in plastic film requires non-toxic, anti-aging and airtight properties, usually polyethylene film, film thickness and color depending on the circumstances. For example, a thick layer of film (thickness 0.12 mm) should be chosen for ammoniated rough straws such as corn stalks. If aminated wheat straw is used, a thin plastic film can be used. The width of the film depends mainly on the size of the crucible and the market availability. The color of the film is generally an anti-aging black film, which is convenient for absorbing sunlight and heat, and is beneficial for shortening the ammoniating time. 2 Liquid ammonia safe operation Liquid ammonia is a toxic and explosive material and should be operated with safety. Operators should be equipped with gas masks, goggles, protective boots, raincoats, rain pants, rubber gloves, wet towels, and there should be plenty of water and vinegar on site. Sheng ammonia bottles are forbidden to collide and knock and prevent sun exposure. Most of the Fluorine-Containing Phenylamine products are a light yellow oily liquid, relatively high density, insoluble in water. Most of them are used in the manufacturing of pesticides and dye intermediates, small part of them can be used as an analytical reagent. The steam or smoke of fluorine-Containing Phenylamine series is irritated to eyes, mucous membranes and upper respiratory. Vapor and air can form explosive mixtures, in case of fire, high-heat combustion caused the explosion. And oxidant may react. Decomposition by high fever and emit toxic gases. In case of high fever, increased pressure within containers, cracking and the risk of explosion. Protective measures must be done carefully during product storage. Once the fire occurred, it must be immediately evacuated from air leakage,personnel to a safe area, prohibit access to the contaminated area. Recommended emergency personnel wearing self-contained breathing apparatus and wear chemical protective clothing. In the ambulance personnel to ensure proper safety measures, immediately use foam, carbon dioxide, dry, sandy soil to put out a fire.
