It can reduce the harm of cold current, when the temperature in the shed is below ℃ for a long time. Mulch such as straw bag non-woven sunshade net should be covered in the greenhouse at night to prevent frost damage and adopt pot fire or furnace fire to temporarily heat up. Open fire should not be used when heating to prevent smoke damage, and a flue should be set up to keep harmful gases outdoors, focusing on the heat preservation and anti-freezing of vegetables and seedlings in the greenhouse. For eggplant seedlings which are in the early stage of raising seedlings, measures such as artificial light supplement and temperature increase can be taken to prevent freezing injury or excessive growth of seedlings; in cloudy and rainy days, the mulch should be properly removed.
The heat preservation of the greenhouse is very high in summer, so all the vents around the vegetable greenhouse must be opened. If the temperature is too high, the top of the vegetable greenhouse can be covered with sunshade net to cool down. In the sunny day, the temperature in the shed should be measured in time. As soon as the temperature rises to more than 30 ℃, open the ventilation vents on both sides and adjust the vents to stabilize the temperature in the shed at 25 ℃-30 ℃ as far as possible. Take light enhancement measures to increase light intensity and prolong light time; select agricultural film with high light transmittance and wipe it frequently to ensure that the surface of agricultural film is clean; cover white plastic film; hang reflective curtain on the back wall; prune and pick leaves in time to enhance the light transmittance of the field.
The basic principle of the car sunshade is also very simple, and the effect of the product is also obvious. it can be used by covering the windshield through the sunshade, and the sunshade product directly retardates the exposure of the sun. in order to achieve the problem of self-cooling in the car. If the seat parts and the center console are exposed to high temperature, the internal parts of the car will be damaged and aged. Sunshade products can effectively block the exposure of the sun, avoid damage to our auto parts and effectively reduce the temperature inside the car.
When the Dongguan rubber compensator is used outdoors or in the spring sun wind pipe, sunshade frames should be set up, and rain, rain and wind turbidity are strictly prohibited. It is forbidden to apply paint and winding insulation materials on the interface surface. Due to the aging problem of rubber and plastic products, it needs to be inspected and replaced in time. The flexible rubber soft joint shall not exceed the offset limit during installation. Dongguan rubber compensator bolts should be installed and gradually charged and tightened to prevent partial leakage. When the rubber soft joint is suspended in the air and assembled vertically, the working pressure of the axial displacement of the Dongguan rubber compensator should be lower than the bearing capacity of the pipe, otherwise the anti-breaking equipment should be installed to avoid breaking during the working process. Rubber soft joints should avoid pyrogen and reactive oxygen species, and direct radiation light source should be prohibited. Exposure to substances that do not meet product standards.
Audio failures are generally divided into two categories: one is caused by improper use, and the other is caused by the weather. The main factors that affect the normal work of car audio in late summer and early autumn are high temperature and humidity. Because the car audio is mostly installed in the upper part of the dashboard, in order to avoid the exposure of the sun, the effect of using sunshade is better. 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 short circuit to burn the main engine. With the coming of the rainy season, the humidity increases, and there is often a layer of fog on the surface of CD records, which makes it difficult to read the disc. It is best to scrub it every once in a while. If the CD drive is modified, in order to avoid dampness, do not install it under the floor and seat, preferably on the high part of the car body, but not on the rear windshield, too high temperature will accelerate the aging of electronic components and laser head.
Hot plate hot fusion welding: thermoplastic welding equipment using surface heat conduction melting to weld the surface of plastic workpiece. It is not limited by the material and size of the parts, and the welding seal is good. It is suitable for the welding of large special-shaped workpieces such as airbag, dashboard, sunshade, car water dispenser, taillight, expansion water tank, brake oil cup and so on.
For people in the city, picnics in the suburbs are the purest taste of spring. In Haikou, it is not difficult to find a grass under the coconut grove. When it comes to picnics, the first thing that comes to mind is the Ten Thousand Green Garden, where there is open grass and coconut trees around for sunshade, which is hardly perfect.
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 flower greenhouse in Guangxi needs the cooperation of a variety of equipment, with the increasing 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.
