Conclusion: after reading this article, I believe you should already know something about the black dots of different sizes of these matrix designs on the edge of the front windshield. Such a black edge design not only improves the beautification effect of your car, but also plays a sunshade role for you when you are driving. When the sun is in direct light, it protects the windshield burst very well, such a small black dot, but it hides a lot of mystery.

The heat preservation work in the greenhouse can be accomplished by using side insulation and top inner insulation curtain (figure 4), as well as internal and external sunshade curtain and top skylight. The heat preservation work can be carried out 2 hours before sunset. Close the top skylight 2 hours before sunset, expand the internal heat preservation, and then gradually expand the internal sunshade and side insulation. All the internal heat preservation, inner sunshade and side heat preservation will be carried out before sunset. If necessary, external shading can also be fully carried out for thermal insulation. When the external solar radiation is less than 300W/m2 (blade stomata closed) and need heat preservation, you can directly turn on internal heat preservation, side heat preservation and internal shading, and close the top skylight at the same time.

When the temperature decreases in winter, choose the plastic film with good transparency and strong insulation to cover the windows, doors and ceilings. When the outdoor temperature drops below zero, the windows and doors are covered with a layer of plastic film, and the ground is padded with rice chaff, rice straw or heat sources in the shed. However, attention should be paid to ventilation to prevent the occurrence of diseases. With the increase or decrease of temperature in spring and autumn, the plastic film should be opened or covered appropriately in time. Mainly do a good job of cooling in summer. When it is too hot, open all the windows and vents, turn on the electric fan to cool down when possible, and hang the sunshade net where the sun shines.

“this is thanks to our digital management and control system, which combines digital agriculture with facility agriculture.” Pointing to the sensors in the greenhouse, he explained to us that all kinds of sensing devices would combine the temperature, humidity, the concentration of carbon dioxide, the temperature of the air and the weather in the soil, and after systematic calculation, automatically control the opening of windows, ventilation, heat preservation, sunshade and hydroponic management of crops. “for example, before planting seedlings, we have already ploughed the land and controlled the temperature and humidity of the greenhouse through systematic data.” For the current spring ploughing preparation work, Fei Jie said in detail.

Sanmenxia deep-fried snack truck manufacturers wholesale price, high current discharge, electric dining car in the start, manned, uphill, as far as possible to step on acceleration, the formation of high current discharge. High current discharge can easily lead to sulfuric acid crystallization, thus damaging the physical properties of the battery board. Advantages: the product has high degree of specialization and standardization. Its public service and cooperation, form and position public service, product specifications, product types, specification parts, original materials are carried out according to the specifications, no matter what kind of vehicle trek in what kind of journey can reach the role. Electric dining car body structure: modern FRP is selected for the exterior of the vehicle, which has the advantages of light weight, corrosion, fire prevention, moistureproof and thickening insulation layer to solve the problem of hot summer and cold winter. All the internal boards are made of food-grade 304 stainless steel, which are clean and beautiful and easy to scrub and clean. Equipped with large sunshade windows, widened display table, bilateral windows more air flow, planning more heart-to-heart talk.

Use or store rubber soft joints, should avoid high temperature, ozone, oil and acid-base environment. Sunshade racks should be built for pipes used outdoors or facing the sun and the wind, and exposure, rain and wind erosion are strictly prohibited. Paint and winding thermal insulation materials are strictly prohibited on the joint surface. Due to the aging problem of rubber products, it should be inspected and replaced in time. It is very important to choose a suitable rubber joint, if you do not choose the right rubber soft joint to work, then the service life of the rubber soft joint will be greatly reduced due to the influence of the external environment and internal medium. not only a waste of resources, but also may lead to heavy damage to the whole pipeline or even have to be rebuilt, then the loss outweighs the gain.
