·Top 10 car companies choose aerospace companies to investigate the cause of Takata airbag failure

According to reports, the Takata Fault Airbag Investigation Alliance, which consists of the world's top ten automakers, recently announced that the group has selected Orbital ATK to investigate the cause of the failure of Takada airbags.

Orbital ATK is an aerospace and defense technology company that specializes in rocket propulsion systems, so it is easy to study the ammonium nitrate propellant composition used in Takada airbags, which is suspected to be the root cause of airbag failure.

The top ten companies that have jointly investigated the Takada airbags are Toyota, Honda, Fiat Chrysler, BMW, Mazda, Ford, Subaru, Mitsubishi, Nissan and General Motors. The group also selected David Kelly, former acting director of the National Highway Traffic Safety Administration (NHTSA), as the head of the investigation project.

Since 1999, Takada has been the only airbag manufacturer to use its current propellant. Former Takata staff and chemists said that the propellant will decompose when exposed to moisture and may cause an explosion if subjected to excessive external force.

The Road Crack Sealing Machine, also called the Asphalt Crack Sealing Machine, concrete asphalt road Crack Sealing Machine, belongs to the road Construction Machinery and is mainly used for the road maintenance. The function of the concrete asphalt road crack sealing machine is to heat the crack after the step of grooving and the crack cleaning, and uniformly fill the sealant into the tank with a caulking gun to complete the joint filling work. 

 Features of crack sealing machine: 

(1) Push-type, independent power, light and practical.

(2) The thermal efficiency is increased by 2 to 3 times, shortening the entire working time. 

(3) Using new technology and foreign technology, the quality of the filling is improved and the cost is reduced. 

(4) The whole machine is equipped with a generator set, which can provide sufficient power. 

(5) Increase the stirring system to make the heating fast and even. 

(6) Applicable to ordinary asphalt and filling glue materials; the jointing material is output through the asphalt pump, and the flow rate can be adjusted. 

(7) The discharge pipe adopts an electric heating system, which effectively eliminates the condensation problem of the caulking material in the hose and reduces the number of manual cleaning of the hose. 

(8) The control panel is operated in a centralized manner, which is simple and labor-saving.
