Description
Technical field
The present invention relates to stainless steel field, and in particular to a kind of anti-bacteria stainless steel.
Background technology
Stainless steel is the abbreviation of stainless acid resistant steel, weak corrosive medium or the steel grade with rustless property such as resistance to air, steam, water
Referred to as stainless steel.China's stainless steel industry development progress is later, since the establishment of the nation to before reform and opening-up, the demand master of China's stainless steel
If based on industry and national defence tip use.After reform and opening-up, the fast development of national economy, living standards of the people it is notable
Improve, pulled the demand of stainless steel.It is China's stainless steel industry entry fast development phase, stainless into after the nineties in last century
The speedup of steel demand is far above global level.Since nineteen ninety, global stainless steel Apparent con- sumption is increased with average annual 6% speed,
And between 10 years of the nineties, China's stainless steel Apparent con- sumption is 2.9 times of world's average growth rate per annum.Into 21 century, China
Stainless steel industry grows at top speed.According to《The market prediction of 2013-2017 China's stainless steel industries and investment strategy planning application
Report》Data statistics, -2006 years 2000, China's stainless steel consumption figure annual average rate of increase was more than 21.17%.Wherein,
2001, China's stainless steel Apparent con- sumption reached 2,050,000 tons, and turning into the first in the world stainless steel more than the U.S. consumes big country.
Outlet aspect, the sustainable growth of international market demand will continue to press on the increase of China's stainless steel demand for exports.According to Macquarie
, it is expected that Chinese stainless steel net export in 2015 will increase to 2,400,000 tons, and by 2016, only about half of RKEF nickel pig iron works above
Factory will form the compact plant with stainless steel.The growth of stainless steel outlet pulls on the increase of domestic supply, it is contemplated that 2016
Stainless steel output will increase by 13.5%, to 23,600,000 tons.But China is at present stainless steel big country, is not also power, stainless
Fall behind level also in the world in the application and development of product made from steel, by being continually striving to, in recent years, some have new function not
Rust product made from steel gradually comes out, and such as has the stainless steel of antibacterial effect, and it is that a certain amount of antibacterial gold is added in common stainless steel
A kind of product that category element Cu, Ag, Zn etc. are thermally treated resulting in, can be used in the fields such as medical treatment, beauty, tableware, and current
Technology it is still immature, it is not only with high costs, and antibacterial ability is limited, and no longer imitated with antibacterial with attrition
Really.
