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 Qinghai photovoltaic greenhouse needs 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 Qinghai photovoltaic greenhouse project, please contact Minghao greenhouse Engineering Construction Company directly.
More installation method has a double-sided detachable, double-sided detachable installation node, which is a good node for bracket installation. At present, the maintenance of ultra-polymer photovoltaic support bearings is developing rapidly. If there is no such use of pressure and mechanical fixation, it is likely to produce a lot of defects. Such as irregular axial loosening, axial pressure deformation, installation collision, photovoltaic support instability and so on. Erguna connected greenhouse tube structure of a variety of assembly plants can use these pipes, electrical equipment to form a workspace, does not require a large amount of investment. This automatic device mainly relies on the computer as the control center to control the facilities such as skylight, sunshade, heat preservation, wet curtain / fan cooling, spray drip irrigation or drip irrigation, seedbed and so on. Of course, the automatic device can not only rely on the control of the computer, it also has acquisition and control.
In order to achieve the welding effect, we can weld multiple points in the same spot, cut and seal, and use the working rules of ultrasonic instantaneous vibration to cut chemical fiber fabric. the highlight of this method is that the incision is smooth, non-cracking and non-wiredrawing. Electric energy is converted into mechanical energy by ultrasonic vibration. Energy is transferred to the contact surface of the plastic workpiece through HORN, resulting in the principle of strong intermolecular friction and heat generation. The product will immediately melt and integrate into the same 360 degrees. Such as: speakers, dashboards, folders, lamps, vacuum cleaners, filters, electric mosquito rackets and so on. Double-head ultrasonic plastic welding machine, can give full play to its welding effect when welding hard plastic materials, ultrasonic welding machine, special scope: used for car body plastic parts, car doors, car instruments, headlamps, mirrors, sunshades, interior decoration, filters, plastic electronic products: prepaid water meters, electricity meters, communication equipment, cordless phones, mobile phone accessories.
Of course, car owners can also choose to use sunshade gears. The most important thing is to block out the sun so that the sun cannot enter the car. To a certain extent, it reduces the combustion effect of the car and avoids the effect that the leather seat and dashboard are damaged by ultraviolet light.
3. The exterior ornaments of the car body mainly refer to decorative strips, wheel covers, signs and embossed words, etc., and accessories such as radiator masks, bumpers, lamps and rearview mirrors also have obvious decoration. 4. Car interior decorations include dashboards, ceilings, sidewalls, seats and other surface decorations, as well as curtains and carpets. Surface finishing materials such as natural fiber or synthetic fiber textiles, artificial leather or multilayer composite materials, skin foam and so on are widely used in cars. On the bus, there are a large number of decoration materials such as fibreboard, cardboard, engineering plastic board, aluminum board, pattern rubber board and composite decoration board. 5, body accessories door locks, door hinges, glass lifts, various seals, windscreen wipers, windwindow scrubber, sunshade, rearview mirror, handle, cigarette lighter and ash box, etc. Radio recorders and pole antennas are often installed in modern cars.

The components and products of foaming materials for lightweight automobile, low carbon, safety protection and NVH are: headrest, dashboard, door lining, steering wheel, tire cover, luggage compartment lining, seat backrest decoration, sunshade, bumper core, air conditioning barrier board, carpet support material, roof, side guard, door inner panel energy absorption protection pad, cushion, muffler plug-in, rear engine compartment, engine shield, Power battery protection system.
More impressive than the appearance are the reborn carriages, where recycled cork, a material that absorbs carbon dioxide during production, has been used on top of dashboards, sunshades and doors as an alternative to traditional styrofoam. All other decorative panels are omitted, exposing the basic metal structure, which is painted blue here.
for car carpets (floor mats), car cushions, safety seats, sun gear and decoration products, surface coverings, curtains, sunshade products, interior decoration products, etc.
In terms of transport, the plastic used by vehicles, trains, ships and other means of transport and corresponding ancillary facilities is increasing year by year on a per-vehicle basis or per-vessel basis. Varieties include fuel tank, bumper, sunshade seat, door handle, steering wheel, dashboard and so on. As a new type of packaging material, plastic has been widely used in the field of packaging. For example, a variety of hollow containers, injection containers (turnover boxes, containers, buckets, etc.). Packaging film, woven bags, styrofoam, binding rope and packing straps, etc.
In addition to its light weight, due to the higher heat resistance of EPP automotive pillows, polypropylene foam is more advantageous than polyethylene foam and polystyrene foam in areas where higher operating temperatures are required, such as sunshades, instrument insulation panels and areas where the temperature between the doors is easy to rise. However, in addition to the field of energy absorption and heat resistance, polypropylene foam also has good thermal weldability, which makes polypropylene foam is also widely used in car sheds, doors, car roofs, carpet support materials, sound insulation panels, door linings and luggage racks, etc., and its good thermal processing type makes it widely used in control boxes, shock-proof panels and other components. In addition, polypropylene foam can also make steering wheel, door inner panel energy absorption protection pad, buffer pad, headrest, toolbox, cushion, dashboard and so on.
