Description
Technical field
The invention belongs to special stainless steel preparation technical fields, and in particular to the side of anti-bacteria stainless steel is prepared under a kind of room temperature
Method.
Background technique
Generally, stainless steel is exactly the steel for being not easy to get rusty, actually a part of stainless steel, existing rustless property, and is had
Acid resistance (corrosion resistance), but this rustless property and corrosion resistance are opposite.Experiments have shown that steel in the weak medium such as big gas and water and
In the Oxidants such as nitric acid, corrosion resistance is improved with the increase of chromium content in steel, when chromium content reaches certain percentage
When, the corrosion resistance of steel mutates, i.e., never anti-corrosion to corrosion-resistant from easily getting rusty to being not easy to get rusty.The classification method of stainless steel
Very much.By institutional framework classification at room temperature, there are martensite type, Austenitic, ferrite and two phase stainless steel;By primary chemical
Compositional classification can be basically divided into straight-chromiun stainless steel and the big system of chromium nickel stainless steel two;Point then there is the stainless steel of resistance to nitric acid, resistance to by purposes
It is stainless can be divided into the stainless steel of resistance to spot corrosion, anticorrosion stress-resistant again by anti-corrosion type point for sulfuric acid stainless steel, seawater corrosionresisting stainless steel etc.
Steel, intergranular corrosion resistance stainless steel etc.;Magnetism-free stainless steel, free cutting stainless steel, low temperature are further divided into not by functional characteristics classification
Become rusty steel, high-strength stainless steel etc..Since stainless steel has excellent corrosion resistance, mouldability, compatibility and in very wide temperature
The number of features such as the obdurability in range, so in the industries such as heavy industry, light industry, daily necessity industry and building decoration
It obtains to be widely applied.
Although stainless steel has the advantages that good corrosion stability and good finish and excellent machining property,
It does not have antibacterial and inhibits the ability of bacterium, is easy infection and breeds bacterium.According to World Health Organization's statistics table in 1998
It is bright: nineteen ninety-five because caused by bacterial infection death toll be 17,000,000 people, as the improvement of people's living standards, people are to locating
Environment and the health of itself increasingly pay attention to, thus promote the research and development of anti-biotic material.Since the eighties, with mouth sheet
It is set for the developed country of representative in household electrical appliance, chemical building material, telecom communication product, food packaging, the normal daily necessity of mouth, bathing
Standby, toy etc. starts using anti-biotic material.
In the prior art, the preparation process of anti-bacteria stainless steel is complex, and equipment cost is high, and energy consumption is big.
