Embodiment
Referring to Fig. 1, Fig. 2, the present invention is that a kind of stalk decomposes test research device, and its structure comprises stalk reaction chamber 1, well heater 2, humidifier 3 and be used for the device 4 of temperature, humidity control; Skin at reaction chamber 1 is provided with shell body 5, with the side a plurality of fluorescent tubes is set respectively above reaction chamber 1, and its lamp illuminance is 0-30000LX, and a side is settled humidifier 3 outside stalk reaction chamber shell 5, and it is communicated with reaction chamber; Settle well heater 2 in the opposite side shell of its shell 5, humidifier and well heater are according to wanting the space size of stalk reaction chamber to select existing product for use.Stalk reaction chamber shell 5 is a wooden frame glazing formula structure, and its front side is provided with glass door 6, is the grid that glass bar and wooden frame are formed around the stalk reaction chamber 1.Exhaust hydrofuge fan 7 is set on stalk reaction chamber shell 5.
The stalk reaction chamber requires specification to be not less than 1m * 1m.Reach the anti-temperature-resistant shape more than 60 ℃ of material requirements of top and bottom around the stalk reaction chamber, help damp and hot exchange, such as making grid with glass bar.The reaction chamber skin has shell body, and its structure is the wooden frame glazing, and glass door is established in the front side, and wooden frame is easy to processing, glass is housed more helps stalk variation observation ward in.To be set at more than 60 ℃ security performance better so experimental temperature is designed to the materials of 5 ℃-50 ℃ devices.The outer side of stalk reaction chamber shell is settled and is settled well heater in the other side shell of humidifier.Humidifier is an external device, belongs to reaction chamber that to be flexible coupling mainly be overall cost and conveniently moving in order to reduce equipment.Well heater is built-in with and is beneficial to heating and heat preservation.Humidifier and well heater are according to wanting the space size of stalk reaction chamber to select existing product for use.Top and rear side are settled fluorescent tube, fluorescent tube and fabricated material require anti-more than 60 ℃ temperature and 90% humidity.Lamp illuminance requires to reach 0-30000LX, and illumination change is opened quantity with the control fluorescent tube and realized.The temperature display controller is installed respectively in warm and humid control and the humidity display controller is realized.
Stalk decomposition experimental technique comprises puts into reaction chamber with sample, sets warm and humid illumination condition, periodic observation stalk changing condition.Stalk decomposes variation and comprises that mainly stalk change color, stalk stretching resistance change, the stalk length variations.The stalk change color reflects with the mode of range estimation and photograph.Stalk decomposes and also can be described as rotten process, so be one of its leading indicator in change color, the change color by stalk is to recently reacting the degree that stalk decomposes.The stalk stretching resistance changes with special-purpose chest expander to be measured.The index that immanent structure when stalk stretching resistance performance is the decomposition of reaction stalk changes, stretching resistance diminish and just illustrate that the stalk degree of decomposition strengthens.The stalk length variations used sieve method to measure, and promptly with the mesh screen in different apertures the stalk classified calculating of different size was gone out the percentage by weight of its different size, and the bright degree of decomposition of novel is big more more for particle, less than 1mm be considered as decompose fully.
Specific embodiment:
With its stalk reaction chamber specification of a stalk decomposer is 1m * 3m.Reach the anti-temperature-resistant shape more than 60 ℃ of material requirements of top and bottom around the stalk reaction chamber, help damp and hot exchange, inwall is fixed with glass and metal card, and both sides are that glass bar is made grid.Reaction chamber shell body, structure are the wooden frame glazings, and glass door is established in the front side, and paste with rubber strip on four limits that door contacts with reaction chamber.The outer side of stalk reaction chamber shell is settled Yadu board YC-DS180 humidifier, and humidification is delivered to the stalk reaction chamber by flexible pipe.Settle " ditch type electric heating device " model N3-V-2 well heater of Beijing triumphant Lay Rake heating equipment company in the other side shell.Top and rear side are settled 30 40W fluorescent tubes.The temperature display controller is installed respectively in warm and humid control and the humidity display controller is realized.
The sample branch of 15 500 grams is opened in the reaction chamber, and stalk length is unified to be 30cm.Design temperature is 30 ℃, and humidity is 80%, and illuminance is 20000LX.Morning, color, pulling force and length variations value were measured in 10 taking-ups weekly.
