A shade arch shed was built in the field. The height of both sides of the arch shed should be higher than 25cm from the nursery bed and above 45cm in the middle. After covering the colorless plastic film, it is covered with about 65% sunshade net, and the edge is compacted to prevent air leakage and ventilation. When the temperature in the shed reaches or exceeds 40 ℃ during the day, remove the film at both ends or in the middle to reduce the temperature to prevent the seedlings from being burned by high temperature; do a good job of heat preservation and moisture preservation by compacting the edge of the shed in winter.
McDonnell Douglas 001 is equipped with a suspended LED display dashboard and a small solar panel mounted on the front sunshade to provide power or replenish batteries for dashboard and body lights. This greatly improves the endurance of the car.
To increase the work efficiency, fourth, the greenhouse support is produced by machinery. Great production efficiency, low requirements for the quality of workers, employing 3-5 people, single machine daily production of rice. Fifth, the greenhouse accessories skeleton machine can produce hollow and solid products. And the height, span, Radian and diameter of the skeleton can be arbitrarily adjusted to produce round, oval and rectangular skeletons. How to adjust the construction temperature of vegetable greenhouse, the main measures to control the temperature of vegetable greenhouse are heat preservation, humidification and ventilation, for example, in winter. For temperature, insulation will be covered outside the hut to meet crop growth needs, and ventilated diseases will keep warm during the hot summer. 1. The roof is covered with sunshades, usually with sunshade and grass curtains. The roof is covered with two layers of sunshade nets, the inner layer is close to the plastic film, and the outer layer is about 15 to 20 centimeters from the top of the roof.
Lan Wenping and his entourage successively inspected five residential areas, including Yonghuafu House in Jianyuan District, Chunjiang New Town Phase I in Yuhuatai District, Keyuan Garden and Yinlong Yayuan in Qinhuai District, and 48 Zhongling Street in Xuanwu District, and sent cool oil, elixir, towels, sunshade hats and other heat prevention and cooling items to the property management and renovation staff of the old district. They told everyone to do a good job of personal protection, avoid high temperature periods, and arrange working hours reasonably. Do a good job in heat prevention and cooling, and urge construction units to take effective heat prevention and cooling and protective measures in time to ensure the safety of front-line workers in the transformation of old residential areas, so as to ensure that the renovation project of old residential areas in the city is carried out in an orderly manner. After the condolences, Lan Wenping and his party went deep into the unit corridor to check the long-term management of beautiful homes, requiring property enterprises to further improve the level of property services, create a comfortable and safe living environment for owners, and effectively meet the livable needs of the people.
Dalian FRP lighting board quotation, the development prospect of sunlight board set daylighting, heat preservation, sound insulation in one, can block the sun and rain, but also heat preservation and light transmission, can be used for greenhouse, furniture canopy, office sound insulation, outdoor advertising light box and so on. Foreign countries even appeared in addition to the supporting structure, pure polycarbonate material of large transparent lighting house, a sunshine, crystal transparent, warm and pleasant. In terms of greenhouse construction, there are greenhouses built with sunboards, gables and sidewalls using sunboards; in terms of greenhouse efficacy, there are production-based greenhouses, trade greenhouses dominated by flower trading centers, and greenhouses dominated by scientific research. Sunpanels are a widely used building material and can also be used in sunshades and canopies.
EPP (polypropylene) foam is a foam material formed by foaming with polypropylene resin as the matrix. It not only has high heat resistance, high impact energy absorption capacity, good resilience and thermoformability, but also can be recycled. It is widely used in bumper, bottom guard, sunshade and other automobile interior and exterior decoration parts. EPP is a kind of high crystalline composite material with excellent performance, which has become the fastest growing and most environmentally friendly anti-pressure buffer thermal insulation material because of its unique and superior properties. EPP can be used in construction, packaging, automobiles, sporting goods, toys, toolboxes, food packaging boxes, household appliances, daily necessities and so on. And EPP is included in the “made in China 2025” key areas of technical materials, known as “green” foam materials.
Thousands of yuan chocolates, patented sunshade hats, big-brand perfumes, necklaces and so on, are both luxurious and practical. Among them, the most thoughtful and highest gift must be the Meitu mobile phone specially customized by Chen Ronglian for the wedding.
Among them, TPU and other polyurethane products can give full play to their unique advantages and have been used in a variety of automotive body parts, including car seats, cushions, headrest, floor mats, dashboards, sunshades, doors, ceiling linings and other internal parts as well as sound insulation and noise reduction materials, sealing materials and so on.
There are also solar buildings, solar thermal power generation and other beneficial technical means to convert solar radiant energy into all kinds of energy that people need. The unit assembly is very free, can be used like building laminated glass, and can be customized according to the exterior design. Installed into the shape of a sunshade, not only will not interfere with the field of vision, but also can play a sunshade effect in summer. When the system uses the controller to adjust the generation power, it will store electricity in the battery and use the inverter to convert the direct current into alternating current, which is directly used to drive the motor of the energy-saving window system and the shutter.
