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 where possible, heating equipment can be used to increase temperature. it is necessary to do a good job in the investigation of hidden risks in production, 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 in advance to prevent stagnant water in the field, and cover the floating surface with covering materials such as plastic film, non-woven cloth or sunshade net 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 not broken, so as to promote the stability of market prices.
As we all know, the main advantage of car shading is to block the sun, so that the light in the action area can not enter the car, to a certain extent, it can reduce the burning inside the car, and prevent leather seats and dashboards from being damaged by ultraviolet rays. But there are still some car owners who doubt whether sunshade really has the above effect.
As a new type of packaging material, plastic has been widely used in the field of packaging. For example, various hollow containers and injection containers (turnover boxes, containers, buckets, etc.). Packing film, woven bag, styrofoam, binding rope and packing tape. In terms of transportation, the plastic used by vehicles, trains, ships and other vehicles and corresponding auxiliary equipment increases year by year by each vehicle or ship. Types include fuel tank, bumper, sunshade seat, door handle, steering wheel, dashboard and so on.
The main factors affecting the normal work of the car stereo are high temperature and humidity, which is because the car audio is mostly installed in the upper part of the dashboard, in order to avoid sunlight, the effect of using sunshade is better. In addition, also note that if your car door and window seals are not strict had better be replaced, otherwise the speakers are vulnerable to corrosion and damage, or even cause a short circuit to burn the main engine. 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.
In the aspect of airbag miniaturization, it is mainly to provide more design space for the peripherals while meeting the lightweight requirements. The miniaturization of the steering wheel airbag improves the degree of freedom in the design of the steering wheel area and helps to improve the overall styling aesthetics of this area, such as the overhead front airbag. Compared with the traditional DAB (steering wheel airbag) and PAB (dashboard airbag) arrangement, the top airbag installs DAB and PAB modules on the roof sheet metal, liberating the steering wheel and front passenger instrument area, and providing space for smart driving, mobile interconnection and other equipment layout. Compared with the traditional front airbag, the top airbag is larger, the bag design is more complex, and the output of the generator is higher, so the airbag assembly is heavier. When arranging, it is necessary to consider the strength of matching with the body sheet metal, the NVH performance, the influence on the front upper visual field, the influence on the sunshade layout design and so on.
(3) semi-rigid foam? It is mainly used to make automobile dashboard, handrail core, sunshade, gearbox top cover, roof lining, door interior panel, bumper core, thrust pad and so on. Because this kind of polyurethane foam has high pressure load capacity, outstanding shock resistance and impact resistance, it can effectively eliminate vibration noise.
The structural design of frame cover fan is adopted to ensure the tightness and waterproof between frame fans, as well as to fully show the permeability of doors and windows on the basis of high safety factor and strong wind pressure resistance of the products, so that the field of vision is more open and the household space can be extended. Under the premise of design requirements, adding external sunshade, awning and appropriately increasing the length of southward balcony can play a certain sunshade effect. Heat-reflecting fabric curtains coated with metal film are arranged on the inside of the window, which has a decorative effect on the front, forming a less mobile space layer about 50mm thick between the glass and the curtains. In this way, a good effect of thermal reflection and thermal insulation can be achieved, but the direct lighting is poor and should be made into a movable type. In addition, a
Another growth factor related to humidity is light. Blueberries are not particularly strong for it, but moderate light is needed to ensure growth. Generally speaking, a sunshade net should be used to isolate part of the exposure when the sun is strong, so as to ensure that the temperature in the blueberry shed should not be higher than 26 degrees. Especially when the summer temperature is particularly high, you can cover two layers of sunshade net on the surface, otherwise the high temperature will make blueberries stop growing. The sunshade net can be removed when the temperature drops in the evening, and if the temperature is too low, the thermal insulation film on both sides of the shed needs to be put down to increase the temperature in the shed. But leave some holes in the perimeter to strengthen an internal air flow. When the weather is bad, one should pay attention to the heat preservation work, and the other is the drainage work.
Many car owners have already installed this car sunshade, easy to install and disassemble, it is easy to shrink and block the front windshield of the car, the heat and light of the vehicle can be kept out of the car all summer, and the license plate is so sweet.
Ji Shuli: “because of the support of the Shenzhen government, we have more than 20 parks that can open camping, which to some extent makes this camping fever even more popular.” Decathlon camping products in this category during the Dragon Boat Festival period compared with the same period last year, has increased nearly ten times, our retail store site, the general public friends are also a lot of outdoor camping related products. Products such as sunshades suitable for parks, small tents with sunscreen, and some tables, chairs and picnic mats are very popular. ”
If the car is parked outdoors and exposed to the sun, if the car is covered with clothes, it can prevent ultraviolet damage to car paint, interior decoration and tires, thus greatly increasing the service life of the car. 3. Sunshade curtain, insulated and good-looking in the sun, the temperature inside the car with closed windows will rise sharply to 50 or 60 degrees Celsius or even higher, and the high temperature will damage the dashboard and leather seats.
