The air pollution in the car is directly related to the vehicle manufacturing technology and the types of parts and parts. the pollution mainly comes from all kinds of accessories in the new car. The first category is seats, including cushions, seat backs, seat covers and seat fabrics, headrest and other materials; the second category is interior decoration, including interior floors, door panels, side panels, rear panels, roof linings, curtains, floor coverings, etc. The third category is the functional category, including car body thermal insulation materials, anti-collision fillers, dashboards, glove boxes, indoor shelf panels or rear windowsill panels, sunshade panels, wheel cover covers, engine cover covers and so on.
With a more balanced center of gravity, lightweight carbon fiber materials, and a new mechanism to wear devices without re-adjustment, this series of optimizations enhance the comfort of the HoloLens. Microsoft has improved thermal management with new soaking plate technology and solved a wide range of physiological changes in the size and shape of the head through a long period of exploration and practice: simply put, the HoloLens2 is basically a general-purpose device that can support glasses users at the same time. The new call fitting system allows users to wear it comfortably for hours. In addition, when you end a mixed reality conversation, you only need to flip the sunshade. All in all, Microsoft believes that “the features mentioned above have more than tripled the measurement comfort and ergonomic design of the device.”
Each RV has more than 600 square lawns, wide space and a camping tent platform in front of the RV.

Scope of application: polyurethane foam is widely used in automotive interior decoration and vibration absorbing parts, such as coating materials, polyurethane rigid plastic panels, polyurethane elastomers, seat soft foam materials, decorative parts, sofa leather, roof accessories; the most widely used is a variety of soft and hard polyurethane foam materials, which have vibration isolation, sound insulation, noise reduction, thermal insulation and thermal insulation. PU can also be made into automotive polyurethane coatings, binders, sealants and so on. The PU representative parts on the car are dashboard, rearview mirror, bumper, seat cushion, headrest, steering wheel, instrument panel anti-vibration pad, pillar decoration, front roof lining, window frame, ceiling and side roof frame decoration, door liner, sunshade panel, rear roof frame decoration and so on.
