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 Kaifeng glass greenhouse requires the cooperation of a variety of equipment, with higher and higher 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. For more information about the construction of Kaifeng glass greenhouse, please contact Minghao greenhouse Engineering Construction Company directly.

When installing the rubber soft joint, the screw of the bolt should protrude the outside of the joint and tighten the bolts on the end face of each flange repeatedly and uniformly according to the method of diagonal pressure to prevent pressure deviation. Tighten the threaded joint evenly using a standard wrench. Do not use an afterburner to slide, slide or break the movable joint. In addition, it should be checked regularly to avoid loosening and causing the disc to fall off or seep. After the rubber soft joint is under pressure for the first time (such as installation, pressure testing) or before it is put back into use after long-term shutdown, it should be re-pressurized and tightened bolts before it can be put into use. When using or storing rubber flexible joints, high temperature, ozone, oil and acid-base environments should be avoided. Sunny outdoor or windward pipes should be set up sunshade. Sun, rain and wind erosion are strictly prohibited. It is forbidden to brush paint and wrap thermal insulation materials on the surface of rubber soft joints. Due to the aging of rubber products, it should be inspected and replaced in time. Return to Sohu to see more

The overhead ventilated roof is widely used in hot summer and cold winter areas in China, especially in the hot and rainy summer, which shows its superiority. The principle of the ventilated roof is to set up a ventilation room layer on the roof. On the one hand, the outer layer of the ventilation room layer is used to block the sun, such as a closed or ventilated air room layer, and the sunshade intercepts the sun directly shining on the roof. The radiant heat makes the roof heat transfer twice, avoiding the direct action of solar radiant heat on the enclosure structure, on the other hand, using the effect of wind pressure and hot pressure, especially natural ventilation, the solar radiant heat absorbed by the upper and lower surfaces of the sunshade in contact with the air is transferred to the air with the wind. The greater the wind speed, the more heat the roof takes away, and the better the thermal insulation effect is, the greater the thermal insulation capacity of the roof is. So as to reduce the effect of outdoor heat on the inner surface.

The sun board integrates daylighting, thermal insulation and sound insulation, which 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.

Coat rack, sunshade panel, storage box, ashtray, gear, central control, automotive electronic system, safety information display system, interior lighting system, interior acoustic system, interior modification, vehicle sealing technology products, interior accessories, car carpets, safety seats, seat covers, headrests, handle covers, handboxes, anti-theft locks, seat belts, sunscreens and decorative products, surface coverings, curtains, sunshade products, etc.

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.

Based on the design concept of Citroen, the interior has the original interior space and can shape the passenger cabin according to the image of the driver. The bright cabin is surrounded by a wide glass area, creating a unique and spacious space, with a horizontal tone design on the dashboard and wooden panels around the front door. In addition, a window is installed at the rear to create an open interior and achieve a 360-degree glass area. For quiet, multi-layer laminated glass (standard equipment of the ShinePack series) is arranged to minimize external noise. The ShinePack system also includes a sliding glass skylight with a sunshade.
