Stainless Steel----Antimicrobial food grade stainless steel
Antimicrobial food grade stainless steel meaning: in the production of kitchen equipment, medical equipment , toiletries and cleaning decoration , people have been looking forward to a new material which have both structural and functional properties, also antimicrobial capacity .
Both structural and functional properties of the new material - both antibacterial stainless steel mechanical properties of structural materials , functional materials have physical and chemical properties, it is like that with stainless steel trim and generally beautify the role as a member , as well as antibacterial , self-cleaning effect of sterilization .
1 , Antibacterial stainless steel profile
Antibacterial stainless steel , is the added amount of the antibacterial metal elements Cu, Ag, Zn and other elements in a common stainless steel. SUS304J1, SUS 304J2, 430J1L, 411SS and treasure and other antibacterial antibacterial stainless steel requirements are met in terms of chemical composition .
2 , Introduction of antibacterial stainless steel
1) SUS304J1 stainless description : SUS304J1 There are two branches of stainless steel , a nickel content of about 7.5% of the market , another nickel content of about 6.2%. Copper content of which were more than 2.0%.Stainless steel introduction : SUS 304J1Compared with ordinary SUS304J1, low nickel content of nickel 304J1 dropped to about 6.2% , the other element content has not changed much .
2) SUS 304J2 Introduction Stainless steel introduction : SUS 304J2
3) 430J1L Introduction : 430J1L is a ferritic stainless steel , 430 Cr content higher contrast , adding Cu, Nb, another lower C, N amount .Stainless steel description : 430J1L
4) 411SS steel description : 411SS 410S lower C content on the basis of increased Cu.Stainless steel description : 411SS
5 ) Antibacterial treasure Description: Antibacterial treasure Baosteel in 2009 in the newly developed steel , which is equivalent to JIS standard of SUS304Cu. Compared with SUS304, increased copper content of about 1% , to increase the antibacterial stainless steel .
Types of antimicrobial food grade stainless steel : produced by antibacterial divided into two types: type and their antimicrobial coating type antibacterial stainless steel. The former can transform existing stainless steel products, namely metal plating on stainless steel material with a germicidal or bactericidal effect of other inorganic materials , but the drawback is easy to wear, easy to aging , with the temperature changes and the external environment and changed so that the loss of the antibacterial stainless steel ; the latter is added during the production of stainless steel metallic element has an antibacterial effect , and then make a special treatment by itself antibacterial stainless steel , it is not the former disadvantages , and low cost, easy to processing.
1 , Antibacterial stainless steel applications :
( 1 ) dining utensils and kitchen supplies ;
( 2 ) Medical Devices ;
( 3 ) food processing equipment ;
( 4 ) pharmaceutical equipment ;
( 5 ) dairy processing equipment ;
( 6 ) Sanitary facilities ;
( 7 ) regular contact with staff and other public facilities .
2 , Antibacterial stainless steel market analysis
At present, China 's annual output of about 10 million tons of stainless steel , of which 70% is plate. It is understood that only Guangdong, with an annual output reached 2.4 million tons of stainless steel sheet , mainly for the production of food utensils , sanitary equipment and household hardware products. Even antibacterial stainless steel can occupy its 10% share , sales volume can reach 60-70 billion, the market prospect is extremely impressive.Currently there is no domestic production and application of antibacterial stainless steel and their products , in addition to Japan have been reported abroad but so far no commercial products to market . Because now mastered the key antibacterial stainless steel production technology, with all the intellectual property , occupies a leading place in the country , at least not encounter strong competition in recent years . Develop antibacterial stainless steel and its products, economic significance.
3 , Antibacterial stainless economic analysis
Antibacterial stainless steel industrial production cost forecastIncrease a ) the cost of raw materialsFor the ferrite and austenite two types of antibacterial stainless steel , are only a small amount on the basis of the original stainless steel components as antibacterial alloying elements Cu , stainless steel compared with the original , raw material costs very little ( less than 3% ) , while smelting , thermal processing , cold and other processes unchanged.2 ) anti-bacterial heat treatmentTwo types of antibacterial stainless steel were needed in the final heat treatment antibacterial , if the establishment of a semi-continuous vacuum heat treatment equipment, increase production costs per ton of not more than 7%.3 ) antibacterial stainless steel industrial production costsIn summary, antibacterial stainless steel under conditions to achieve large-scale production , compared with the original stainless steel (0Cr17 and 0Cr18Ni9), increased production costs will not exceed 10 %. While the addition of antibacterial function , increase product prices will certainly be higher than 10% , such as price antibacterial fabrics, antibacterial ceramic , antimicrobial coating materials and other antibacterial products than the corresponding original increase of 25 % or more .Antimicrobial food grade stainless steel applications : Currently the field of materials for the " sterilization" and "antibacterial" there is no clear definition. Antibacterial generally understood to inhibit bacterial growth , growth and reproduction , sterilization is to kill microorganisms. Antibacterial stainless steel can not make it on the adhesion of the bacteria multiply , the bacteria are killed or inhibited in a low level state, but does not change the intensity of ordinary stainless steel , corrosion resistant , beautiful features, has a very broad application prospects . Look forward into people's homes.
