Ndeipi chikafu giredhi isina tsvina simbi?
Simbi yechikafu isina tsvina iri mumutsara ne '' People's Republic of China National Standard GB9684 ' STHINELLE STEEL STEL. Zviri mukati mehutsi hwechromium chakaderera pane icho chevanowanzo simbi simbi simbi.
Zviratidzo zvinotsausa: Chikafu cheGiredhi Stainless Simbi chinoreva chikamu icho chiri kusangana nechikafu chekudya chikafu chemichero, uye chikafu chinofanira kuita zvimwe zvinodiwa zvekuchengetedza. kushandisa mari yakawanda proction , acid process Nekuti process yekugadzirwa proction
Musiyano uripo pakati pekudya giredhi simbi uye 304 simbi isina simba : Iko kushandiswa kwesimbi zvigadzirwa zvinorema simbi kutama kunopfuura mwero, zvinogona kukuvadza hutano hwevanhu. Naizvozvo, simbi yesimbi yekubika inoda kurova chiyero pakati pePorrosion uye kuchengeteka. Pakanaka neChrotion kupesana kunowedzerwa, asi huwandu hwechiratidzo , ' ' chezvakarongeka zvinowedzera
Nei iyo nyika standard isingatsanangurire muganho wekufambisa weManganese?
Chimwe chikonzero ndechekuti nekuwedzera kweManganese mune simbi yesimbi , kupesana kwayo kurwisa uye kurwisa kurwisa kunowedzerawo. Kamwe chete Manganese zvirimo zvinosvika kune imwe nhanho, chigadzirwa hachigone kushandiswa sechibiki kana simbi isina tsvina. Asi kunyangwe pamatanho akanyanya eManganese, pane kazhinji hapana hutano mhedzisiro. Saka nepo nyika yekuchengetedza chikafu isingadzorere monganese mandanese chenyika
Chaiwo mwero
All kinds of food storage containers and food processing machinery should choose austenitic or ferritic stainless steel (1Cr18Ni9Ti,0Cr19Ni9, 1Cr18Ni9, 1Cr17Ni2). Kuti uwane chikamu chekugadzirisa chekuchera chishandiso chinodhonzera chishandiso chinogona zvakare kusarudza marensianite simbi (0cr13, 1CC13, 3CC13).
Chaizvoizvo zvemuviri uye makemikari zviratidzo zvinotevera:
Item Austenitic Stainless Steel Ferritic Martensitic Stainless Simbi
Tungamira (muPB), mg / l 4% acetic acid kunyudzwa mhinduro ≤ 1.0 1.0.
Chromium (in cr), mg / l 4% acetic acid kunyudzwa mhinduro ≤ 0.5
Nickel (in ni), mg / l 4% acetic acid inodonha mhinduro ≤ 3.0 1.0.
Cadmium (muCD), mg / l 4% acetic acid solution ± 0.02 0.02.
Arsenic (AS), MG / L 4% acetic acid solution ± 0.04 0.04.
Ongorora: Mamiriro ese ekunyanyisa anokandwa 30min uye ipapo tembiricha yemakamuri ye 24h.
Chikafu chegiredhi simbi isina simbi Yakatemwa pombi ine huwandu hwakawanda hwekushandisa, mukati uye kunze kwekuda. Simbi isiriyo yeLsel yelating yelding kurapwa inguva yakakosha, 0.5mm inogona zvakare kuzadzisa mhedzisiro yekukanda kwemukati.
Kana iri giredhi giredhi isina tsvina yakasarudzika pombi pasi pemamiriro ezvinhu akajairika anofanirwa kukandwa mukati nekunze, panguva imwecheteyo inoda Weld achikuya uye inopenya inosimbisa . Iko kudikanwa kwemukati uye kwekunze kuputika hakuna chekuita nemadziro madziro, chete nemamiriro ekushandisa. Kukudza kwemadziro kwakanyanyisa kutetepa kwemukati kuraswa hakuna kukura zvakanyanya padambudziko, nekuti kunze kwekukanda kunogona kunge kuri kwakaderera.
Kana ikarukwa pombi , hazvina basa mukati nekunze. Zvekutarisawo kuyamwisa kweyako tube. Seamless tube haigoni kukandwa mukati. Iwe haugone kutaura kuti rusvingo rwamadziro rwe0,5 zvakatetepa. Nekuti kana iwe uine girazi remadziro Saka zvinoenderana neyakateya yeyako tube.
Zvimwe pombi yako yakareba, iyo madziro madziro yakatetepa, nekuti kupukunyuka kwemukati uye kwekunze kwekuona kushandiswa kweiyo seti, iwe hauna zvido zvepamusoro, hapana chikonzero chekuwedzera mari isiriyo.
