●?? One is to clear the ditch and reduce dampness. Clean up the ditches in time to reduce the field humidity and prevent waterlogging damage caused by stagnant water in the field; the whole bed in the greenhouse is covered with plastic film, and the ditch is covered with dry straw to reduce the humidity in the greenhouse. The second is to keep warm against the cold. Pay attention to the heat preservation of vegetables, check the leakage of the greenhouse film, close the shed at the right time in the morning and evening, properly uncover the film and ventilation when the temperature is high, adjust the temperature and humidity in the shed, and increase the light. Open-field vegetables can be tied around the waist, floating surface covering sunshade net, straw and other anti-freezing. Third, strengthen management. Do a good job in pruning vegetables in the field, beating leaves, hanging vines, fertilizing, cultivating soil and so on. Fourth, post-disaster management. After the freezing weather of rain and snow, timely ventilation and humidity drop, spraying to prevent disease, frostbite disease cleaning and other measures, strict control of watering, sunny weather should pay attention to timely return to the curtain to prevent plant seedlings from withering and dying.
Tianjin sun board, which integrates daylighting, heat preservation and sound insulation, 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.
Car umbrellas are useful. According to the sunscreen principle and the shape of the car, the car sunshade covers from the front windshield to the rear windshield. The sun umbrella which can effectively reduce the temperature rise in the car when parking at high temperature is called car sunshade.
Flame retardant and other characteristics of anti-impact and corrosion resistance has a long service life to greatly reduce the pressure and shear stress on the surface of the material stack. Autumn rain-proof electric car rain-proof sunshade provides spring sand protection with sponge or soft cloth to scrub the plate, and then rinse with clean water. Function 9, bicycle shed use environment and temperature: used in weak acid-base environment, the temperature is 40Mel 80; the humidity is 10% Mel 90%? Landscape? The production steps of the rain-proof awning of electric vehicles provide ordinary people with sand protection in spring, sunshade in summer, rain protection in autumn and cold in winter.
Car shipping companies always pay attention to the sound affected by high temperature and humidity. Now most cars are equipped with CD equipment. The main factors that affect the normal work of car audio in 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.
The beneficial effect of the utility model is that the sunshade picnic insulation bag of the utility model not only has excellent high temperature heat preservation and low temperature heat preservation effect, but also has a skeleton inside the package body, which can be used as a stool, and is built with detachable sunshade umbrellas, which is more suitable for carrying out, more powerful in function and more practical.
Guancheng toilet aluminum alloy doors and windows company, rain-proof shutters are used in computer rooms or other public places that need ventilation and rain protection, heat insulation and air flow regulation, and it is composed of rain-proof blades with water collecting ditch, side frame with dripping frame and streamlined adjusting blades, which not only has the advantages of single-layer rain-proof blinds, but also allows staff to adjust the opening of rain-proof shutters according to indoor temperature or ventilation demand. Single-layer rain shutters are divided into vertical and horizontal, mainly used for large shopping malls, exhibition halls, garages and other places of the facade and top sunshade, also has the role of anti-theft insurance. 4. keep the surface of the curtain dry.
The internal thermal insulation system can be divided into the top and the side, and the principle is to reduce the heat loss in the shed by arranging automatically contractible thermal insulation curtains on the top and side parts, so as to achieve the effect of thermal insulation. At the same time, after the expansion of the internal thermal insulation system, the moisture in the shed is isolated so as to reduce the role of condensed water on the roof. Like the sunshade system, the top internal thermal insulation system is closed by aluminum alloy moving edge, deceleration motor, transmission rack and hot-dip galvanized push-pull rod.
