EPP (polypropylene) foam is a foam material formed by foaming with polypropylene resin as the matrix. It not only has high heat resistance, high impact energy absorption capacity, good resilience and thermoformability, but also can be recycled. It is widely used in bumper, bottom guard, sunshade and other automobile interior and exterior decoration parts. EPP is a kind of high crystalline composite material with excellent performance, which has become the fastest growing and most environmentally friendly anti-pressure buffer thermal insulation material because of its unique and superior properties. EPP can be used in construction, packaging, automobiles, sporting goods, toys, toolboxes, food packaging boxes, household appliances, daily necessities and so on. And EPP is included in the “made in China 2025” key areas of technical materials, known as “green” foam materials.
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.
At first, the study seemed to show that using sunshades was more effective than window masks. Later, it was determined that the sunshade provided insulation only for the dashboard area. In a vehicle without a window film, the average sunshade can only cool the air temperature in the car by about 2 degrees Celsius. A car with a window mask can lower the ambient temperature at the front and rear of the car, cooling the air in the car by about 8 degrees Celsius.
Such as: speakers, dashboards, folders, lamps, vacuum cleaners, filters, electric mosquito rackets and so on. The application range of double-head ultrasonic plastic welding machine: used in car body, door, lights, car reversing mirror, sunshade, interior parts, filter, bumper, cable, oil cup, water tank, fuel tank, air duct, exhaust gas purifier, tray filter plate and other automotive products plastic parts. Plastic electronic products for double-head ultrasonic plastic welding machine: prepaid water meter, communication equipment, cordless telephone, mobile phone accessories.
6. the interior and exterior decoration engineering design the automobile interior and exterior decoration includes the automobile exterior decoration and the interior decoration, because it is also called the body accessory equipment because it is installed on the body. 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. 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.
It is necessary to strengthen the temperature control during the autumn breeding season of Chinese bees, although the bees have a certain ability to regulate the temperature in the hive, but it is more conducive to the autumn reproduction of the beehive if it can provide a suitable temperature, such as appropriately expanding the hive door or building a sunshade on the beehive when the temperature is generally high in the early stage, while strengthening the heat preservation of the hive when the temperature is generally low in the later stage, such as properly reducing the hive door or covering the hive with insulation.
To increase the work efficiency, fourth, the greenhouse support is produced by machinery. Great production efficiency, low requirements for the quality of workers, employing 3-5 people, single machine daily production of rice. Fifth, the greenhouse accessories skeleton machine can produce hollow and solid products. And the height, span, Radian and diameter of the skeleton can be arbitrarily adjusted to produce round, oval and rectangular skeletons. How to adjust the construction temperature of vegetable greenhouse, the main measures to control the temperature of vegetable greenhouse are heat preservation, humidification and ventilation, for example, in winter. For temperature, insulation will be covered outside the hut to meet crop growth needs, and ventilated diseases will keep warm during the hot summer. 1. The roof is covered with sunshades, usually with sunshade and grass curtains. The roof is covered with two layers of sunshade nets, the inner layer is close to the plastic film, and the outer layer is about 15 to 20 centimeters from the top of the roof.
In addition to its light weight, polypropylene foam has a higher heat resistance, polypropylene foam is more advantageous than polyethylene foam and polystyrene foam in areas where higher operating temperatures are required, such as sunshade panels, instrument insulation panels and places where the temperature between the doors is easy to rise.
In the design and development of interior fabric, we often use fiber materials with fine denier and high hole to reduce the rigidity of the fiber and increase the soft touch of the fabric. at the same time, we can also use different yarn shrinkage to achieve the shrinkage elasticity and thick feeling of the fabric; in order to ensure the straightness of the sunshade fabric, we need to stiffen the fabric. In order to increase the friction coefficient of the seat synthetic leather surface, we choose the surface embossed texture with a strong sense of particles; in the coating of the dashboard or door panel area, in order to meet the delicate comfort in the process of use, we often use fine frosted texture and matte gloss treatment at the same time.
Safety is of utmost importance, especially when traveling with children. Make sure to include a first-aid kit in your travel bag, stocked with essentials such as band-aids, antiseptic ointment, and pain relievers. Additionally, consider adding a window shade or a sunshade to protect your kids from harmful UV rays and keep the car cool during sunny days.
