Product Description
RUINENG Alumina Ceramic Ball
Alumina ceramic Balls are produced by using industrial alumina and fire-resistant kaolin as the main raw materials through scientific compounding, shaping and high-tempreature calcination. Fire resistance Ceramic Ball has high mechanical strength and long service life, and refractory ceramic balls have good chemical stability, It has excellent high tempreature resistance and the highest heat-resistant tempreature which can reach as high as 1900 °C.
Application
Alumina ceramic Balls are widely used in petrolem chemical ,fertilizer ,natural gas and environmental protection industry. With stable chemical features and a low rate of water absorption,they can resist high temperatures and high pressure,and also can resist the corrosion of acid,alkali and some other organic solvents,and can stand the change in temperature during the application.Ceramic balls can increase the distribution spots of gas or liquid, and to support and protect the activating catalyst with low strength.

GM's chief financial officer Dan Ammann and Exxon are currently reviewing product projects, cutting marketing expenses, consolidating their engines and vehicle manufacturing platforms. General Motors even shut down some of the office's thermostats.
In the first half of this year, GM’s operating profit margin was 5%, while Ford’s operating profit margin was 7.5% and VW was 7.8%. GM has always expected to surpass Ford and Volkswagen in operating profits and regain the throne of global sales championships.
General Motors has not announced its third-quarter financial report yet. Analysts predict that its net income in the third quarter will fall from $2.16 billion in the same period last year to $1.6 billion.
GM Exxon Says First Half Profits Need to Further Cut Costs
GM’s profit for the first half of the year was as high as US$6.3 billion, which was the highest year-over-year profit in 20 years, but General Manager Dan Ickerson still asked for further cost reductions. It seems to be sending a message to employees that the profit in the first half was not good.
