Sisebenzisa iikuki ukuphucula amava akho.Ngokuqhubeka nokukhangela le ndawo, uyavumelana nokusebenzisa kwethu iikuki.Iinkcukacha ezithe xaxe.
Intsimbi engatyiwayo ingaphezulu nje kwentsimbi ekwaziyo ukumelana nomhlwa.Insimbi engenasici isoloko ikhethwa njengento eguquguqukayo kwizicelo ezininzi ngenxa yamandla ayo, ukuxhathisa ukubola kunye nokukwazi ukulungelelanisa iimeko ezithile.
304 304L 316 316L ababoneleli ngepleyiti yentsimbi engatyiwa eTshayina
I-Stainless Steel 304 lelona bakala lisetyenziswa kakhulu kwintsimbi yentsimbi.Yi-chromium-nickel austenitic steel stainless kunye nomxholo wekhabhoni encinci kunye ne-chromium ephezulu kunye ne-nickel kune-AISI iindidi ezingama-301 kunye ne-302.Ineempawu ezilungileyo zobushushu obunyusiweyo kunye nokuqina okuhle kumaqondo obushushu aphantsi.Ifaneleka kakuhle kwi-welding kwaye apho imveliso egqityiweyo kufuneka ixhathise iindlela ezinzima zokubola.

Oku akusebenzi nje kuphela kwiintlobo zeekhemikhali ezahlukeneyo ezenza insimbi engenasici, kodwa nakwiingubo ezahlukeneyo kunye nonyango oluphezulu olusetyenziswayo ngokuxhomekeke ekupheleni kokusetyenziswa kwemveliso.
IBanga le-2B lolona nyango luxhaphakileyo lusetyenziswa kumphezulu kwishishini lensimbi engenasici.I-semi-reflective, igudile kwaye ifanayo, nangona ingesiso isipili.Ukulungiswa komphezulu linyathelo lokugqibela kwinkqubo: ishidi lensimbi liqala ukubunjwa ngokucinezela phakathi kwemiqulu ekuphumeni kwesithando somlilo.Ithi ke ithambe ngokufakwa i-anneal kwaye iphinde igqitywe ngemiqulu.
Ukususa izinto ezingcolisa umphezulu, umphezulu ufakwe iasidi kwaye ugqithiselwe phakathi kweerola zokupholisha amaxesha amaninzi ukufezekisa ubukhulu obufunwayo.Yaba yile pasi yokugqibela eyakhokelela ekugqityweni kwe2B.
I-2B yomgangatho osemgangathweni kumabakala aqhelekileyo ensimbi engenasici, kuquka i-201, i-304, i-304 L, kunye ne-316 L. Ukuthandwa kwe-2B yokupolisha, ngaphezu koqoqosho kunye nokumelana nokugqwala, ilele ekuphuculeni ngokulula ngevili lelaphu kunye. ikhompawundi.
Ngokuqhelekileyo, i-2B yokugqiba intsimbi isetyenziselwa ukulungiswa kokutya, izixhobo zokubhaka, izitya, iitanki zokugcina, kunye nezixhobo zonyango kwaye ihlangabezana nemigangatho ye-USDA kula mashishini.
Le ndlela ayimkelekanga xa imveliso yokugqibela iyisisombululo esitofwayo okanye esine-otic.Oku kungenxa yokuba izithuba okanye iipokotho zinokuthi zenze kumphezulu wesinyithi.Ezi voids zinokubamba ukungcola ngaphantsi kwendawo epholisiweyo okanye kwintsimbi.Ekugqibeleni, ezi zinto zangaphandle zinokubaleka kwaye zingcolise imveliso.I-Surface electropolishing yeyona ndlela ifanelekileyo kunye necetyiswayo yokuphucula ukuguda komphezulu kwezo zicelo.
I-electropolishing isebenza ngokusebenzisa imichiza kunye nombane ukugudisa iindawo eziphakanyisiweyo kumphezulu wentsimbi engenasici.Nokuba kukho umzi-mveliso osetyenzisiweyo iSmooth 2B Coating, eyona ndawo yentsimbi engenasici ayizukubonakala igudileyo xa inyusiwe.
Uburhabaxa obuphakathi (Ra) busetyenziselwa ukubhekisa kubumpuluswa bomphezulu wesinyithi kwaye luthelekiso lomahluko ophakathi phakathi kwamanqaku aphantsi naphezulu kumphezulu ngokuhamba kwexesha.
Ngokuqhelekileyo, i-factory fresh steel stainless ene-2B yokugqiba inexabiso le-Ra kuluhlu lwe-0.3 micron (0.0003 mm) ukuya kwi-1 micron (0.001 mm) ngokuxhomekeke kubukhulu bayo (ubukhulu).I-Surface Ra ingancitshiswa ibe yi-4-32 intshi encinci nge-electropolishing efanelekileyo, kuxhomekeke kwiimpawu zetsimbi.
Ukugqitywa kweklasi ye-2B kufezekiswa ngokucinezela izinto eziphathekayo ngee-roller ezimbini.Abanye abaqhubi bafuna ukulungiswa kwe-trim emva kokuhlaziywa okanye ukulungiswa kwenqanawa okanye ezinye izixhobo.
Nangona umphezulu ogqityiweyo ofunyenwe ngoomatshini okanye nge-electropolishing akulula ukuphinda uvelise kwakhona, unokusondelelana kakhulu, ngakumbi ngokubhekiselele kumaxabiso eRa.Njengomphumela wonyango olululo lwe-electropolishing, ukusebenza ngcono ngakumbi ngokwemigaqo yokulungiswa kwezinto kunokufezekiswa kunonyango lwangaphambili olungagqitywanga lwe-2B.
Ke ngoko, uqikelelo lwe-2B lunokuthathwa njengesiqalo esihle.Iingubo ze-2B zineenzuzo ezaziwayo kwaye zinoqoqosho.Inokwandiswa ngakumbi nge-electropolishing ukuze kugqitywe kakuhle, imigangatho ephezulu kunye noluhlu lweenzuzo zexesha elide.
Olu lwazi luye lwaqinisekiswa kwaye lwatshintshwa kwizinto ezibonelelwa yi-Astro Pak Corporation.
