  随着社会的发展,防虫网批发零售发展趋势越来越好,那么今天由济南2020年马会开奖结果网业有限公司说一说防虫网的设计理念及遵守原则都有哪些?
  With the development of society, the development trend of insect prevention network wholesale and retail is getting better and better. So what are the design concepts and principles of insect prevention network as mentioned by Jinan Chunxuan Network Industry Co., Ltd?
  密度
  density
  防虫网的密度通常以目数来表示,即每平方英寸的孔眼数。根据温室作物主要害虫的种类和大小,温室防虫网适宜的目数为20目~50目,具体目数应根据主要防治病虫害的种类和大小来选择设计。
  The density of the net is usually expressed in mesh, that is, the number of holes per square inch. According to the species and size of the main pests of greenhouse crops, the suitable mesh number of greenhouse insect control net is 20-50 mesh, and the specific mesh number should be designed according to the species and size of the main pests.
  按虫害特征选择
  Select according to pest characteristics
  根据作物受虫害时间的长短、虫害的种类等选择防虫网的种类。作物如果只是短时间受虫害,可选择轻质、便宣的防虫网;作物如果在不同时期遭受不同虫害,应按体形更小的害虫特征选用相应目数的防虫网。
  According to the length of time that crops are damaged by pests and the types of pests, the types of insect control nets are selected. If the crop is only damaged by insects for a short time, it can choose light and convenient insect control net; if the crop is damaged by different insects in different periods, it should choose the corresponding mesh of insect control net according to the smallest pest characteristics.
  强度
  Strength
  防虫网的强度与所用材料、编制方法和孔眼大小有关,金属网的强度要高于其他材料制成的防虫网,防虫网应具有一定的抗风能力。
  The strength of the net is related to the materials used, the preparation method and the size of the hole. The strength of the metal net is higher than that of the net made of other materials. The net should have certain wind resistance.

  规格
  Specifications
  2020开奖结果产品的宽度系列为800mm、1000mm、1100mm、1600mm、1900mm、2500mm等,2020开奖结果产品的宽度和长度的具体规格也可由供应商和使用者双方商定。
  The width series of the products are 800mm, 1000mm, 1100mm, 1600mm, 1900mm, 2500mm, etc. the specific specifications of the width and length of the products can also be agreed by the supplier and the user.
  使用寿命
  Service life
  由聚乙烯、聚丙烯和尼龙等材料制成的防虫网,应具有一定的抗老化能力,在按2020开奖结果产品说明书使用的条件下,其使用寿命应不低于3年。
  The insect proof net made of polyethylene, polypropylene and nylon materials should have certain anti-aging ability. The service life of the insect proof net should not be less than 3 years under the conditions of product instructions.
  颜色
  colour
  防虫网的颜色应以白色和无色透明为主,也可以是黑色或银灰色的。白色和无色防虫网的透光性好,黑色防虫网的遮光效果好,银灰色防虫网则避蚜效果好。
  The color of insect screen should be mainly white and colorless transparent, or black or silver gray. White and colorless nets have good light transmittance, black nets have good shading effect, and silver grey nets have good aphid avoidance effect.
  材料
  Material Science
  制作防虫网所用材料应具有防潮、耐腐蚀、抗紫外线和耐老化的能力,并应符合国家材料标准的有关规定。
  The materials used for making the insect screen shall be moisture-proof, corrosion-resistant, UV resistant and aging resistant, and shall conform to the relevant provisions of the national material standard.
  防虫网
  Insect proof net
  防虫网的安装事项
  Installation of insect net
  确定防虫网的安装位置
  Determine the installation position of insect net
  防虫网通常安装在进风口和排风口,在风向比较固定的地方,迎风侧窗上的防虫网比背风侧窗上的防虫效果好。对于开有侧窗和天窗的自然通风温室,可在侧窗和天窗是上同时安装防虫网,效果更好。
  The insect screen is usually installed at the air inlet and the air outlet. In the place with fixed wind direction, the insect screen on the windward side window is better than that on the leeward side window. For the natural ventilation greenhouse with side window and skylight, insect proof net can be installed on the side window and skylight at the same time, with better effect.
  对于育种和科研用温室,对防虫的要求很高,除在进、出风口安装防虫网外,风机口上也应安装防虫网,风机口防虫网宜安装在风机内侧,并保持干燥。对温室的所有缝隙均应进行适当的密闭处理。
  For breeding and scientific research greenhouses, there is a high demand for insect prevention. In addition to installing insect prevention nets at the air inlet and outlet, insect prevention nets should also be installed at the fan port. The insect prevention nets at the fan port should be installed inside the fan and kept dry. All gaps in the greenhouse shall be properly sealed.
