PA has good impact resistance and strength. In the car body, it is mainly used to manufacture wheel front and rear cover, handle, door lock, seat belt fixing hinge, dashboard, fender, sunshade clamp, swing arm of seat back, gear, etc., in which the PA consumption of wheel cover is about 2kg/, which is a big market of nylon. However, when nylon is used as a large component, because the water absorption will cause size change or strength reduction, it can not fully maintain the performance of the parts, so it is necessary to modify PA.
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 and so on. Each company may divide these parts into different departments.
At first, the improved locomotive did not have any front windows. After the EF58 electric locomotive was put into operation, the locomotive was modified according to the climatic environment along the line, such as installing an icicle cutting plate above the front window glass to prevent the running locomotive from hitting the icicles falling at the entrance of the tunnel and causing damage to the window. and add a cover to the whistle. In the later period, when the locomotive was transferred to the warmer climate area, the whistle cover of the locomotive was removed, but some locomotives only removed the icicle cutting plate and retained the whistle cover during car body maintenance. In addition, some EF58 electric locomotives in Hiroshima area are also equipped with front window windows, but the purpose is completely different from that of crossing the line, but it is used as a sunshade.
Mugaodi is a big brand in the camping circle. this one is more suitable for going out to party and camping, with a larger sunshade area, only a piece of cloth above, not very windproof, suitable for barbecue and picnic, and the price is not expensive. Party activities can be recommended.
The evaporation of water in the plastic film prevents the large amount of air humidity in the shed after watering. Select natural materials for moisture absorption, such as rice straw, wheat straw, quicklime and other materials to adsorb water vapor or fog between rows, and select insulation curtain materials with good moisture permeability and moisture absorption, such as non-woven cloth can condense dew on the inner surface, and prevent dew from falling on the plant. Thus reduce the air humidity, ploughing dehumidification by cutting off soil capillaries, can prevent soil capillary water rising to the surface, can avoid a large number of soil moisture evaporation, with the increase of summer temperature. How to properly cool the greenhouse has become an important work of daily management, the following we will introduce the following six measures, 1, external sunshade system. Is to keep the excess sunlight out of the greenhouse. Form shade to protect the crops in the greenhouse.
The temperature has suddenly soared in the past two days. I went out at noon like teppanyaki, standing in the sun for half an hour, and the sunshade hat was so hot that I dared not touch it directly with my hands. I think many parents in many parenting groups have begun to stock up on summer artifacts, holding small fans, cool towels and other gadgets to help in the group, which is very annoying. I am not interested in these at all. It is not suitable for children to use these. They are easy to catch cold.
6. Avoid direct sunlight and high temperature in the car. Dashboards and central control areas are mostly made of engineering plastics. plastics will age and fade when exposed to the sun for a long time, although manufacturers will do strict aging tests during development, but it is good to pay more attention. So it is necessary to keep a sunshade pad all the time;
