In the severe winter weather, the small arch shed in the greenhouse should be covered with a layer of straw buns or covered with quilts to keep warm, and then covered with a layer of film. Add windbreak and anti-freezing barrier. The combination of straw and old film into a cold wall, placed in the north of the vegetable greenhouse, as a wind barrier, can reduce the harm of cold current. When the temperature in the greenhouse is below ℃ for a long time, the mulch such as straw bag non-woven sunshade net should be covered in the greenhouse at night to prevent frost damage and take basin fire or furnace fire to heat temporarily. When heating, open fire can not be used to prevent smoke damage, it is necessary to set up a flue to put harmful gases outside. Focus on the heat preservation and anti-freezing of vegetables and seedlings in the greenhouse. For eggplant seedlings that are in the early stage of raising seedlings, measures such as artificial light supplement and temperature increase can be taken to prevent frost damage or excessive growth of seedlings; in cloudy and rainy days, the mulch should be properly removed to make the plants see as much light as possible.
Since the world is colorful, and we choose a variety of Japanese half-skirts, then our modeling should have more performance. If you want to be more aging and elegant, you might as well match the rest of the items to make the styling more stylish and dazzling. Whether it is an exquisite bag or a sweet sunshade hat, it can be natural and beautiful with a Japanese half skirt.
When selecting soft rubber joints, we should pay attention to selecting the appropriate product model. This can be considered from the aspects of the pressure of the wiring pipe, the interface mode, the material and the amount of repair, and the total number is selected according to the noise reduction offset. Pipe connectors that cause instantaneous working pressure to be higher than pressure should also be selected. (for example, when the pipe runs the transient working pressure > 1.0MPa, the 1.6MPa in the connector operation should be selected. When transient working pressure > 1.6MPa, 2.5MPa connector should be selected). When the pipe material is acid, alkali, oil, high temperature and other materials, the working pressure of the rubber soft joint should be one grade higher than the pipe pressure. Outdoor applications or pipes facing the sun and solar wind should be covered with sunshades to prohibit exposure, rain and wind erosion. The surface of the joint shall not be brushed with sand control and thermal insulation material. Due to the aging of rubber products, it should be inspected and replaced immediately.
11. After the concrete has been poured, covering or spray curing should be carried out immediately before the initial setting. Concrete thermal insulation materials can be made of plastic film, geotextiles, gunny bags, flame retardant quilts and so on. If necessary, wind shielding shed or sunshade greenhouse can be set up. In the thermal insulation maintenance, the temperature difference and cooling rate of the concrete pouring body should be monitored on the spot, and when the measured results do not meet the requirements of the temperature control index, the thermal insulation maintenance measures should be adjusted in time.
It is necessary to do a good job of heat preservation at night and ventilation and humidity reduction during the day. The night temperature in early spring is still low, which needs to be covered with grass curtain, sunshade net, non-woven fabric or multi-layer mulching; the temperature rises rapidly during the day, coupled with the current high humidity in the field, so it is necessary to timely control and adjust the indoor air humidity and temperature in the shed. On a sunny day, after the temperature picks up after 08:30, ventilation should be carried out gradually, and the mulch such as non-woven fabrics should be removed in time to increase the light; the shed should be closed and the warmth should be covered before 4 p.m. In case of cloudy and rainy weather, it is still necessary to properly ventilate during the day to reduce the humidity in the shed. In addition, in the alternate season of late winter and early spring, the weather changes greatly, so we should pay close attention to the weather changes to prevent the occurrence of late spring cold. After the middle of April, the average temperature is stable above 15 ℃, which can remove the inner shed, prolong the opening time of the outer shed, increase the light time and intensity, reduce the humidity in the shed, and control the occurrence and prevalence of diseases such as leaf mold and gray mold.
Many car companies do not make these parts themselves, but by supporting manufacturers. The interior design mainly includes dashboard, steering wheel, seat, seat belt, airbag, carpet, sidewall interior decoration, sunshade panel, handrail, car rearview mirror and so on.
