For this reason, the competent departments of agriculture and forestry in many places have issued various measures to require farmers to do a good job in the prevention and remediation of crops in order to deal with the “late spring cold.” For example, for the vegetable greenhouse, the relevant departments stipulate that “when the temperature in the greenhouse is below 0 ℃ for a long time, straw bags, non-woven cloth, sunshade net and other mulch should be added in the greenhouse at night to prevent frost injury and take basin fire or fire temporary heating. At the same time, open fire can not be used when heating to prevent smoke damage, it is necessary to set up a flue to discharge harmful gases outdoors. Strengthen the coverage in time to promote heat preservation and anti-freezing. ”
These parts are mainly produced by supporting manufacturers. Interior design includes dashboard, steering wheel, seat, seat belt, airbag, carpet, sidewall interior decoration, sunshade panel, handrail, car rearview mirror and so on. Exterior design includes front and rear bumper, glass, door anti-collision decoration strip, intake grille, luggage rack, skylight, rearview mirror, door structure and accessories and sealing strip.
Of course, the cooling work of the greenhouse in summer can not rely entirely on the greenhouse insulation quilt, but also should take some other measures accordingly. Can cooperate with enhanced ventilation to cool down, but it should be noted that it is best to set up a wind shield in the tuyere to avoid the cold wind blowing directly on vegetable and fruit noodles; you can also use a sunshade net to cool down, and the shading rate of the shading net can be selected according to your needs. The advantage of shading net is that it can not only prevent sunburn vegetables, but also allow part of the light to illuminate the interior of the greenhouse, ensuring the photosynthesis of vegetable leaves; you can also take spray cooling methods.
1. Do a good job of cold resistance and anti-freezing measures. For Fritillaria thunbergii, Yuanhu, saffron and other traditional Chinese medicine, can cover straw, sunshade net and other anti-freezing. Control the water content of Dendrobium candidum matrix, seal the greenhouse film, prevent cold air from entering the greenhouse, and multi-layer covering can be used in the greenhouse. For breeding seedlings, potted flowers and some Lunar New year Flowers and precious flowers, it is necessary to do a good job of heat preservation in the shed, and lilies and Lunar New year flowers need to strengthen heating measures, especially when low temperature comes, pay attention to watch at night and heat up continuously to prevent frost damage caused by sudden changes in temperature in the shed. For the gerbera produced in the simple greenhouse, when the low temperature freezing comes, the film needs to be added to resist the low temperature, and a layer of non-woven cloth can be added in the greenhouse to enhance the thermal insulation performance.
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. The main design of exterior parts includes front and rear bumper, glass, door anti-collision decoration strip, intake grille, luggage rack, skylight, rearview mirror, door mechanism and accessories and sealing strip. At this stage, VR allows designers to place virtual dolls in digital car models to verify the accessibility of each interior and man-machine interface. This feature increases the cost of trial and error for automakers before they go into production without VR, while VR perfectly solves the problem of long testing cycles for all ergonomics and car interiors.
two。 Sunshade. The membrane structure Suzhou parking shed adopts polycarbonate material with high impact resistance, and its strength is about 200 times that of glass. The raw materials are imported from Germany and processed in China. Through the double-sided co-extrusion process, the anti-ultraviolet material (UV) is added, which can effectively block more than 98% of the ultraviolet rays, protect the car surface paint, effectively control the continuous rise of the interior temperature, and in direct sunlight. The temperature in the car can reach more than 60 ℃ and can be effectively reduced to about 40 ℃ after installation. At the same time, it also has flame retardant effect, and can be used normally for more than 30 years in the environment of-30 ℃ to 60 ℃ (137 ℃ thermal deformation). The downcomer is made of high-strength aluminum alloy and has a unique user-friendly design to avoid the second pollution to the car and you when the roof water falls to the ground. The structure is reasonable and easy to clean, and it is convenient for the Suzhou parking shed with membrane structure to remove dirt from the pipe.
Car sunshade: made of multi-layer bubble film and aluminum foil. Aluminum foil effectively reflects light, thus reducing thermal radiation and blocking heat conduction. At the same time, ultraviolet rays are also reflected by aluminum foil, reducing the damage caused by ultraviolet rays to leather seats and dashboards.
Under the premise of meeting the interior design requirements of the building in Hangzhou, adding external sunshade panels, awnings and appropriately increasing the length of the 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, installing blinds with certain thermal reflection on the inside of the window can also obtain a certain thermal insulation effect.

Himalayan four-sided mesh design is ventilated and breathable, the sunshade cloth can be pulled up to resist the sunlight, and the hall strut can be propped up to form a courtyard for shelter from wind and rain at the entrance, covered with picnic mats, the tent can be picked up as high as 210cm, in and out, there is no need to bend down, there is no suppression to greatly improve the comfort of the tent, four-sided gauze + tent cloth design, multiple functions, put away the tent cloth when the sun is shining Let the outdoor party closer to nature, improve the comfort of the account, and can pull up the tent cloth when it rains, effectively shielding from the wind and rain.
