The yin and yang shed refers to the construction of a greenhouse in the shading area of ​​the back wall of the solar greenhouse. The solar greenhouse on the sunny side is called a sun shed, the shady shed is on the sunny side, the shady shed and the sun shed share a wall, and a hot air stove is installed in the sun shed. The planting of the thermophilic and high-priced vegetables is the mainstay; the shade shed is mainly planted with cool green leafy vegetables or used for summer seedlings, and can also be used for placing potted plants. The yin and yang shed hot blast stove project can solve the problems of idle land in shaded greenhouses and greenhouses due to high temperature, high humidity or even cloudy diseases, increasing land utilization from 43.8% to 68.8%, increasing production by 30% and reducing costs by 15%. -20%, increase the output value by more than 25%.
In order to promote the development of the vegetable and flower industry, at the beginning of last year, technical staff of the Agriculture, Forestry and Animal Husbandry Bureau of Xingqing District organized a seminar on the use of yin and yang sheds and hot blast stoves held by the Ministry of Agriculture and Animal Husbandry of the autonomous region and declared the “sunshine greenhouse—hot blast stove and shade shed. The “Production Technology Research and Demonstration†project won funding from the Agriculture and Animal Husbandry Department of the autonomous region and the Science and Technology Bureau of the Xingqing District, experimented in a vegetable science and technology demonstration park in Daxin Town and Duzheng Town, built 5 demonstration yin and yang sheds, and installed 10 hot stoves. , carry out vegetable seedlings and production of vegetable flowers and sheds. Yang Peng can supplement the extra calories in the noon to the shade canopy to increase its temperature by 3°C to 5°C. During the winter night, it can be heated in the greenhouse stove for 1 hour to increase the nighttime temperature in the greenhouse by 7°C, reduce the air humidity, and reduce the occurrence of pests and diseases. It is reported that after the spring of this year, the technology will be widely promoted.
1.Used as excellent external lubricant in PVC profile,, pipe, pipe fitting, foam board, WPC products ,etc. It has good late-period lubricating ability ,and will bring more glossy appearance and lower processing torque.
2.Used as efficient dispersant in masterbatch , filled masterbatch, modified masterbatch and functional masterbatch. It makes the products inorganic components and pigments dispersed better, and get more beautiful appearance .
3.Used as excellent external lubricant in PVC stabilizer ,especially in Ca-Zn stabilizer. Additional use suitable inner lubricant, it will highly improve the overall effect of stabilizer and increase the cost-effective correspondingly.
4.Used in hot melt adhesives can better adjust the products viscosity and hardness, improve its fluidity. .
5.Used in paint, coating and the road marking paint,its main performance is heat resistance, deforming ,leveling, anti-setting and dispersion. It can increase the products surface hardness, wear-resistance and anti-smearing properties.
