Round Capillary Stainless hlau yeeb nkab
Cov yam ntxwv ntawm 304 cov khoom siv stainless hlau yeeb nkab
1. Cov yeeb nkab steel hlau ua los ntawm 304 yog ib puag ncig zoo heev, nyab xeeb thiab txhim khu kev siv.
2. Lub 304 stainless hlau yeeb nkab tuaj yeem khoov nrog kev ua haujlwm siab Gini mus rau qhov loj.Peb paub tias kev tsim kho ib puag ncig feem ntau cuam tshuam rau cov yeeb nkab steel hlau, tab sis cov neeg ua haujlwm yuav ua tiav kev tsim kho raws li qhov txawv txav ntawm cov yeeb nkab stainless hlau.
3. Cov yeeb nkab 304 stainless hlau muaj qhov ua tau zoo heev rau cov kua qaub thiab alkali corrosion.Muaj cov yeeb yaj kiab tiv thaiv zoo heev rau sab nrauv ntawm cov yeeb nkab stainless hlau, tab sis nws nyuaj heev.Txawm hais tias cov yeeb nkab stainless hlau puas lawm, tsuav yog muaj oxygen nyob ib puag ncig Yog tias nws yog, ces nws yuav rov tsim dua sai, thiab yuav tsis muaj xeb.
4. Qhov zoo ntawm 304 stainless hlau yeeb nkab yog lub teeb heev, yog li nws yooj yim rau nqa thiab nruab, uas txo cov nqi ntawm qhov project.
Mechanical zog thiab cov yam ntxwv ntawm cov kav hlau stainless
Stainless hlau yog hais txog cov hlau uas tsis muaj zog corrosive media xws li cua, chav, thiab dej, thiab tshuaj lom neeg corrosive media xws li acid, alkali, thiab ntsev, los yog stainless acid-resistant steel.Hauv kev siv tswv yim, cov hlau uas tsis muaj zog corrosive media feem ntau hu ua stainless hlau, thiab cov hlau uas tiv taus tshuaj lom neeg corrosion yog hu ua acid-resistant steel.Vim qhov sib txawv ntawm cov tshuaj muaj pes tsawg leeg ntawm ob, tus qub tsis tas yuav tiv taus cov tshuaj lom neeg corrosion, thaum lub tom kawg yog feem ntau stainless.Kev tiv thaiv corrosion ntawm stainless hlau nyob ntawm cov alloying ntsiab muaj nyob rau hauv cov hlau.
Cov yam ntxwv tseem ceeb ntawm stainless hlau:
1.Weldability
Cov khoom siv sib txawv muaj cov kev xav tau sib txawv rau kev ua haujlwm vuam.Ib chav kawm ntawm tableware feem ntau tsis xav tau kev ua haujlwm vuam, thiab txawm tias suav nrog qee lub lag luam lauj kaub.Txawm li cas los xij, cov khoom lag luam feem ntau xav tau kev ua haujlwm zoo ntawm cov khoom siv raw, xws li cov khoom siv hauv chav kawm thib ob, lub khob thermos, cov kav dej steel, lub tshuab rhaub dej, cov khoom siv dej, thiab lwm yam.
2. Corrosion kuj
Cov khoom siv stainless hlau feem ntau yuav tsum muaj kev tiv thaiv corrosion zoo, xws li Chav Kawm I thiab II cov tais diav, cov tais diav hauv chav ua noj, lub tshuab rhaub dej, cov khoom siv dej, thiab lwm yam. Qee cov tub lag luam txawv teb chaws kuj ua cov tshuaj tiv thaiv corrosion ntawm cov khoom: siv NACL aqueous tov kom sov nws mus rau boiling, thiab ncuav nws tom qab ib lub sijhawm.Tshem tawm cov tshuaj, ntxuav thiab qhuav, thiab ntsuas qhov hnyav los txiav txim siab txog qib ntawm corrosion (Ceeb toom: Thaum cov khoom polished, Fe cov ntsiab lus hauv daim ntaub abrasive lossis ntawv xuab zeb yuav ua rau xeb ntawm qhov chaw thaum lub sij hawm kuaj).
3. Polishing kev ua tau zoo
Nyob rau hauv lub neej niaj hnub no, stainless hlau cov khoom yog feem ntau polished thaum lub sij hawm tsim khoom, thiab tsuas yog ob peb yam khoom xws li dej rhaub thiab dej dispenser liner tsis xav tau polishing.Yog li ntawd, qhov no yuav tsum tau hais tias polishing kev ua tau zoo ntawm raw khoom yog zoo heev.Cov yam tseem ceeb uas cuam tshuam rau kev ua haujlwm polishing yog raws li hauv qab no:
① deg tsis xws luag ntawm raw khoom.Xws li khawb, pitting, pickling, thiab lwm yam.
②Qhov teeb meem ntawm cov khoom siv raw.Yog hais tias lub hardness tsawg dhau lawm, nws yuav tsis yooj yim rau polish thaum polishing (cov cuab yeej BQ tsis zoo), thiab yog tias qhov hardness tsawg dhau, qhov tshwm sim ntawm cov txiv kab ntxwv tev yog ib qho yooj yim los tshwm rau saum npoo thaum lub sij hawm sib sib zog nqus nqus, yog li cuam tshuam. cov cuab yeej BQ.BQ khoom nrog siab hardness kuj zoo.
③ Rau cov khoom sib sib zog nqus, cov me me dub thiab RIDGING yuav tshwm sim ntawm qhov chaw ntawm qhov chaw uas muaj ntau qhov deformation, yog li cuam tshuam rau BQ kev ua haujlwm.
4. Thaum tshav kub kub kuj
Thaum tshav kub kub tsis kam txhais tau hais tias stainless hlau tseem tuaj yeem tswj nws lub cev zoo thiab cov khoom siv kho tshuab ntawm qhov kub thiab txias.
Cov txiaj ntsig ntawm cov pa roj carbon: Cov pa roj carbon zoo tsim thiab ruaj khov hauv austenitic stainless hlau.Cov ntsiab lus uas txiav txim siab austenite thiab nthuav dav thaj av austenite.Lub peev xwm ntawm carbon los tsim austenite yog kwv yees li 30 npaug ntawm cov npib tsib xee, thiab cov pa roj carbon monoxide yog cov khoom sib txuas uas tuaj yeem ua kom muaj zog ntawm austenitic stainless hlau los ntawm cov khoom siv ntxiv zog.Cov pa roj carbon kuj tuaj yeem txhim kho qhov kev ntxhov siab corrosion tsis kam ntawm austenitic stainless hlau hauv cov tshuaj chloride siab heev (xws li 42% MgCl2 boiling tov).
Txawm li cas los xij, hauv austenitic stainless hlau, carbon feem ntau suav tias yog cov khoom tsis zoo, feem ntau vim tias nyob rau hauv qee qhov xwm txheej (xws li vuam lossis cua sov ntawm 450 ~ 850 ° C) hauv cov hlau tsis muaj corrosion, carbon tuaj yeem cuam tshuam nrog cov pa roj carbon monoxide. hlau.Chromium tsim high-chromium Cr23C6-hom carbon tebchaw, uas ua rau depletion ntawm lub zos chromium, uas txo cov corrosion kuj ntawm hlau, tshwj xeeb tshaj yog tsis kam mus rau intergranular corrosion.yog li ntawd.Feem ntau ntawm cov tshiab tsim chromium-nickel austenitic stainless hlau txij li xyoo 1960 yog cov roj carbon tsawg uas muaj cov ntsiab lus tsawg dua 0.03% lossis 0.02%.Nws tuaj yeem paub tias vim tias cov ntsiab lus carbon tsawg zuj zus, qhov cuam tshuam ntawm intergranular corrosion ntawm cov hlau txo.Thaum cov ntsiab lus carbon qis dua 0.02% muaj cov txiaj ntsig pom tseeb tshaj plaws, thiab qee qhov kev sim kuj tau taw qhia tias carbon kuj nce pitting corrosion nyiam ntawm chromium austenitic stainless hlau.Vim tias muaj kev phom sij ntawm cov pa roj carbon monoxide, tsis yog tsuas yog cov ntsiab lus carbon yuav tsum tau tswj kom tsawg li sai tau hauv cov txheej txheem smelting ntawm austenitic stainless hlau, tab sis kuj nyob rau hauv cov txheej txheem tom ntej ntawm kub, txias ua hauj lwm thiab kev kho cua sov kom tsis txhob muaj cov pa roj carbon ntau ntxiv. nto ntawm stainless hlau thiab tsis txhob chromium carbides Precipitate.
5. Corrosion kuj
Thaum tus nqi ntawm chromium atoms nyob rau hauv cov hlau tsis tsawg tshaj li 12.5%, cov electrode muaj peev xwm ntawm cov hlau tuaj yeem hloov tam sim ntawd los ntawm qhov tsis zoo rau qhov zoo electrode.Tiv thaiv electrochemical corrosion.
Txoj kev ntxuav ntawm stainless hlau yeeb nkab
1. thawj zaug siv cov kuab tshuaj ntxuav steel nto, qhov chaw ntawm cov organic teeb meem tshem tawm,
2. Tom qab ntawd siv cov cuab yeej tshem tawm xeb (xov hlau txhuam), tshem tawm cov xoob lossis qaij nplai, xeb, vuam slag, thiab lwm yam.
3. kev siv pickling.
Txoj kev sib txuas
Feem ntau muaj plaub txoj hauv kev los txuas cov kav hlau stainless:
1. Compression kev twb kev txuas-------- Nws muab faib ua ib qho compression thiab ob chav compression.Ob chav clamping yog txoj kev sib txuas ruaj khov tshaj plaws.Siv radial shrinkage sab nraud quab yuam (hydraulic pliers) los tuav cov yeeb nkab ntawm cov yeeb nkab, thiab hla cov dej nres ntawm O-ring kom ua tiav qhov kev sib txuas.Yooj yim rau kev khiav lag luam, zoo sealing thiab tsis tshem tawm.
2. Ntiv nplhaib expansion txuas--------- Siv radial contraction sab nraud quab yuam (hydraulic pliers) kom clamp cov yeeb nkab ntawm cov yeeb nkab, thiab hla cov dej nres ntawm cov hlua khi hlua khi dav kom ua tiav cov txiaj ntsig kev sib txuas, detachable, yeeb nkab txheej txheem. txhim kho thiab nce lub nplhaib convex ntawm cov yeeb nkab kawg;sealing kev ua tau zoo yog dav dav, thiab tus nqi ntawm cov yeeb nkab fittings yog siab.
3. Welded kev twb kev txuas--------- Cov txheej txheem kub yaj yog siv los txuas ob qhov txuas kom ua tiav cov txiaj ntsig ntawm kev sib txuas.Kev sib txuas lub zog yog siab, thiab nws yog ib qho nyuaj rau kev tiv thaiv roj ntawm vuam seam kom ncav cuag tus qauv, uas ua rau cov vuam seam yooj yim rau xeb, uas ncaj qha txo cov kev pab cuam lub neej ntawm cov kav dej;qhov kev txhim kho zoo yog nyob ntawm cov neeg ua haujlwm vuam cov txuj ci, thiab qhov zoo yog qhov nyuaj rau kev ruaj khov.
4. Self-locking kev twb kev txuas--------- ua ntej yog siv rau me me-inch yas hose kev twb kev txuas, ceev installation tsis muaj cuab yeej.Sab hauv ntawm lub interface yog yooj yim rau loosen thiab xau, thiab sealing kev ua tau zoo tsis zoo.
