Do a good job in the production and supply of vegetables in winter and spring. Facility vegetable production should do a good job in facility repair and heat preservation, adopt measures such as multi-layer film mulching and adding thermal insulation quilts to strengthen facility heat preservation, and if possible, heating equipment can be used to increase temperature. completely eliminate the hidden dangers of production risks such as old facilities, heating charcoal and fire. Conscientiously implement measures such as clearing communication canals, timely uncovering and replenishing light, scientific fertilization and water pipe, etc., and make use of fine weather to restore ventilation and dehumidification in time after rain and snow, reduce the humidity of the shed, and reduce the occurrence of diseases. Vegetables in the open field should clear the ditch and manage the soil moisture in advance to prevent stagnant water in the field; if possible, cover materials such as plastic film, non-woven cloth or sunshade net should be directly covered with floating surface to prevent cold; mature vegetables should be harvested and listed in time to ensure that the main vegetable products are not out of stock and unbroken, so as to promote market price stability.
In addition to its light weight, due to the higher heat resistance of EPP automotive pillows, polypropylene foam is more advantageous than polyethylene foam and polystyrene foam in areas where higher operating temperatures are required, such as sunshades, instrument insulation panels and areas where the temperature between the doors is easy to rise. However, in addition to the field of energy absorption and heat resistance, polypropylene foam also has good thermal weldability, which makes polypropylene foam is also widely used in car sheds, doors, car roofs, carpet support materials, sound insulation panels, door linings and luggage racks, etc., and its good thermal processing type makes it widely used in control boxes, shock-proof panels and other components. In addition, polypropylene foam can also make steering wheel, door inner panel energy absorption protection pad, buffer pad, headrest, toolbox, cushion, dashboard and so on.
Now? Some cars are equipped with CD equipment, and the main factors that affect the normal work of car audio in autumn are high temperature and humidity. Because of the car stereo? Installed in the upper part of the dashboard, the sunshade is more effective in order to avoid the exposure of the sun. If the door and window sealing strip is not strict, it should be replaced, otherwise the loudspeaker is easy to rust and damage, or even cause? The road burns down the mainframe.
Foshan Chenghang plastic Technology Co., Ltd. for you a detailed interpretation of UOJWGl Jieyang City pc Sunshine wavy tile manufacturers spot related knowledge and details, sunlight board set lighting, heat preservation, sound insulation in one, sunshade and rain, can also be used for greenhouse, furniture canopy, office sound insulation, outdoor advertising light box and so on. In foreign countries, in addition to supporting the structure, the pure polycarbonate material quantity of large-scale bright lighting house, a sunshine, crystal transparent, warm and annoying.
Many music-loving car owners will install a CD frame on the sunshade to facilitate access to and play CDs, but when the vehicle collides and brakes urgently, the objects in the car will produce inertia, and the discs in the CD rack are also likely to be affected by inertia, flying out to scratch the members of the car, and serious cases may die.
The warm sunshine room uses strong thermal insulation profiles and glass, and even has auxiliary heating equipment, sunshade system and ventilation system, which can meet the activities, work and living of people who are not affected by the season.
(2) adjustable shading facilities should be used in ultra-low energy consumption buildings. The heat absorbed by the sun absorbed by the external sunshade surface can be adjusted automatically or manually according to the sun height angle and outdoor weather conditions, and the proportion of the sun absorbed by the external sunshade surface is smaller than that of the inner or middle shade. It is the most suitable shading form for ultra-low energy consumption buildings. The schematic diagram of the adjustable external shade and adjustable sunshade of the lifting louver is shown in figure 10;
Although the solar greenhouse has a very good thermal insulation performance, but from the point of view of safety, heating equipment is still an important factor. The southern part of our country generally does not need to heat up, but if we encounter bad weather continuously, we still need to use the energy stored in the greenhouse itself, otherwise it will not be able to meet the growth of vegetables. Therefore, whether in the south or north, heating equipment has always been a necessary protective measure. The technical aspect requires that in the equipment configuration of solar greenhouse, the configuration of thermal insulation equipment should be demonstrated in great detail. Of course, the work of Kaifeng glass greenhouse requires the cooperation of a variety of equipment, with higher and higher temperature requirements, especially in autumn and winter production, external sunshade system, internal thermal insulation system and window opener and fan, wet curtain and other equipment need to be applied. For more information about the construction of Kaifeng glass greenhouse, please contact Minghao greenhouse Engineering Construction Company directly.
In the recent weather in Wuhan, it is recommended to go out for a picnic with sunscreen, mosquito repellent, hat (sunshade and photo taking), garbage bags, and try to choose a place with tree shade. It is recommended to have a picnic at 4-5pm with good sun light.
The material is mainly shown in strong adhesion with all kinds of skin and skeleton materials, high pressure load, good shock-proof and anti-impact performance, and can eliminate vibration and noise. it is very suitable for making automobile dashboard, handrail core, headrest and sunshade. Because the semi-rigid PU foam is porous, it gives the dashboard good resilience, absorbs 50-70% impact energy, has high safety, heat resistance, cold resistance, firmness and durability, and has a good feel.
