Qhov kev ua tau zoo tshaj ntawm titanium coils stems los ntawm cov cim physicochemical ntawm titanium. Ua ntej, nws muaj qhov ntom ntom (kwv yees li 4.51 g / cm³) tab sis muaj zog tshwj xeeb, suav nrog qhov siab tshaj plaws ntawm tag nrho cov hlau.
Thib ob, titanium muaj zog heev corrosion kuj vim nws muaj zog affinity rau oxygen. In oxygen-containing environments, it forms a dense, strongly adhering, and inert oxide film on its surface, protecting the substrate from corrosion. Cov yeeb yaj kiab no tseem nyob ruaj khov txawm tias nyob hauv oxidizing, nruab nrab, thiab tsis muaj zog ntawm kev tshaj tawm. Cov oxide zaj duab xis no khaws nws cov khoom ntawm qhov kub thiab txias hauv qab 315℃thiab tuaj yeem ua tus kheej - kho lossis rov tsim dua tom qab kev puas tsuaj. Tsis tas li ntawd, titanium coils muaj cua sov zoo heev thiab qis -kub tsis kam. titanium alloys tshiab tuaj yeem siv tau rau lub sijhawm ntev ntawm qhov kub ntawm 600℃lossis siab dua, thaum qis- kub titanium alloys (xws li GR5) tuav zoo ductility thiab toughness ntawm kub xws li ntawm -196℃rau -253 degree, tsis txhob txias brittleness. Lwm cov nta suav nrog kev ua tsis yog{17}} sib nqus, tsis muaj tshuaj lom, thiab biocompatible nrog tib neeg cov ntaub so ntswg thiab ntshav, ua rau nws haum rau kev kho mob; muaj lub ntsej muag du uas tsis yooj yim rau scaling, thiab nyias-walled tsim uas txhim kho kev sib hloov hluav taws xob; raws li zoo damping kev ua tau zoo thiab zoo heev tshav kub exchanger kev ua tau zoo.
Corrosion Resistance:Kev tiv thaiv ib puag ncig hnyav Nyob rau hauv cov txheej txheem ntau lawm ntawm kev lag luam metallurgical, cov hlau raug nthuav tawm rau ntau cov xov xwm uas muaj corrosive, xws li acids, alkalis, thiab dej ntsev. Cov khoom siv hlau niaj hnub muaj qhov cuam tshuam rau corrosion hauv cov cheeb tsam hnyav, ua rau cov khoom siv tsis tu ncua thiab ua rau lub neej luv luv. Titanium coils muab cov kev daws teeb meem zoo tshaj plaws rau qhov teeb meem no. Titanium coils muaj kev tiv thaiv corrosion zoo heev rau cov xov xwm corrosive xws li chlorides, sulfuric acid, thiab hydrochloric acid. Thaum siv sijhawm ntev -, lawv tuaj yeem tiv thaiv kev yaig ntawm cov xov xwm no, tswj kev ua haujlwm ruaj khov. Qhov no tsis tsuas yog ua kom ntev kev pab cuam lub neej ntawm cov cuab yeej siv thiab txo lub sijhawm poob vim cov khoom puas tsuaj, tab sis kuj tseem txhim kho tag nrho cov kev ua tau zoo, txuag cov lag luam metallurgical cov nqi thiab sijhawm.
Kev ua cua sov:Qhov tseem ceeb ntawm Kev Txhim Kho Kev Siv Hluav Taws Xob Hauv kev lag luam metallurgical, kev siv hluav taws xob muaj txiaj ntsig ua lub luag haujlwm tseem ceeb hauv kev ua tiav kev siv hluav taws xob zoo. Titanium coils, nrog lawv cov khoom siv hluav taws xob zoo heev, ua lub luag haujlwm tseem ceeb hauv daim teb no. Lawv tuaj yeem ua cov cua sov sai, ua rau cov txheej txheem sib pauv cua sov ua kom zoo dua thiab nrawm dua, yog li txhim kho kev siv hluav taws xob thiab txo kev siv hluav taws xob. Lub caij no, lub coefficient ntawm thermal expansion ntawm titanium coils yog ze rau cov hlau. Cov yam ntxwv zoo no tiv thaiv cov cuab yeej deformation lossis kev puas tsuaj los ntawm qhov sib txawv ntawm thermal expansion, ua kom ruaj khov ntawm cov khoom siv thaum tshav kub kub pauv thiab muab kev txhawb zog rau kev txuas ntxiv thiab kev ruaj ntseg ntawm metallurgical ntau lawm.
Lub teeb yuag yam ntxwv:Kev txo qis ntawm cov khoom siv loj hauv kev lag luam metallurgy yog qhov tseem ceeb rau kev txiav txim siab. Piv nrog cov khoom siv hlau ib txwm muaj xws li cov hlau tsis muaj steel, titanium coils muaj qhov zoo ntawm qhov hnyav. Lawv qhov hnyav dua ua lub luag haujlwm zoo hauv kev txo qis tag nrho ntawm cov khoom siv. Cov yam ntxwv no tsis tsuas yog pab txo qhov hnyav ntawm cov khoom siv nws tus kheej thiab lub siab ntawm lub hauv paus qauv, tab sis kuj txo cov nqi tsheb thauj mus los thiab teeb meem kev teeb tsa thaum lub sij hawm thauj khoom thiab kev teeb tsa. Tshwj xeeb tshaj yog nyob rau hauv qee qhov tshwj xeeb metallurgical scenarios nrog kev txwv hnyav, lub teeb yuag yam ntxwv ntawm titanium coils ua rau lawv qhov kev xaiv tsis tseem ceeb, txuas ntxiv kev pab cuam lub neej ntawm cov khoom siv.
Mechanical Properties:Qhov chaw tsim khoom nyob rau hauv kev lag luam metallurgical feem ntau yog hnyav heev, yuav tsum tau siv cov cuab yeej los tiv thaiv cov mob hnyav xws li kev kub siab, kub kub, thiab kev kub ceev. Lub zog siab thiab tawv ntawm titanium alloys endow titanium coils nrog cov khoom siv kho tshuab zoo, ua rau lawv ruaj khov nrog cov kev ua haujlwm hnyav. Nyob rau hauv lub zog sab nraud thiab kev cuam tshuam, titanium coils tsis tuaj yeem ua rau deformation lossis tawg, tswj cov qauv kev ncaj ncees thiab kev ua haujlwm ruaj khov, ua kom muaj kev nyab xeeb thiab txhim khu kev qha khoom siv. Qhov no txo cov kev pheej hmoo ntawm kev nyab xeeb thiab kev cuam tshuam ntawm kev tsim khoom los ntawm cov khoom siv tsis ua haujlwm.
Hnav Resistance:Ib txoj hauv kev zoo los txo cov nqi kho mob. Nyob rau hauv cov txheej txheem metallurgical ntau lawm, cov kua dej yaig thiab cov khoom tawg yog feem ntau ua rau cov khoom puas. Cov khoom siv hlau niaj hnub ua rau hnav sai sai hauv qhov chaw ib puag ncig, ua rau cov khoom siv tsis zoo los yog ua tsis tiav. Titanium coils, nrog rau lawv zoo heev hnav tsis kam, zoo tiv thaiv cov abrasive yam. Lawv lub ntsej muag du tsis tsuas yog txo cov kua dej yaig tab sis kuj tiv thaiv kev scaling, txo qhov nyuaj ntawm kev tu cov cuab yeej. Qhov no tso cai rau cov cuab yeej tswj xyuas kev ua haujlwm zoo thaum lub sijhawm ua haujlwm ntev -, txo qhov zaus thiab tus nqi ntawm kev saib xyuas, txhim kho kev tsim khoom, thiab muab kev txhawb zog rau kev ruaj khov ntawm cov tuam txhab metallurgical.
Peb cov titanium coils muaj cov txheej txheem hauv qab no:Lawv tuaj yeem tiv taus kev ua haujlwm siab feem ntau yog li ntawm 1 txog 6 MPa, thiab ntev -lub sijhawm ua haujlwm kub siab tshaj 200 degree, nrog qee cov alloys ncav cuag qhov kub siab dua. Feem ntau cov yeeb nkab diameters li ntawm 16 mus rau 60 hli, nrog cov phab ntsa tuab xaiv raws li qhov chaw ua haujlwm thiab kev ntsuas siab. Cov txheej txheem tsim khoom yog xav tau; siab - cov khoom zoo yuav tsum tau siab - purity titanium cov ntaub ntawv (xws li GR1 thiab GR2 qib) thiab ua tiav los ntawm precision machining, inert gas shielded welding (xws li argon arc vuam), thiab kev kho deg (xws li anodizing) los xyuas kom meej cov yeeb nkab phab ntsa precision, weld zog, thiab corrosion kuj. Kev ntsuas kev ua tau zoo yuav tsum muaj kev ntsuas siab, ntsuas qhov cuam tshuam, thiab ua raws li cov qauv tsim nyog xws li ASTM B338 thiab GB / T 3624-2019.
Vim lawv cov corrosion kuj, siab zog, thiab zoo biocompatibility, titanium coils muaj ntau yam kev siv. Hauv kev lag luam tshuaj, lawv tau siv rau reactor txias, sib pauv cua sov hauv cov khoom siv distillation, thiab hauv cov txheej txheem xws li kev tsim cov nitric acid thiab titanium chloride. Hauv kev lag luam hluav taws xob thiab petrochemical, lawv tsim nyog rau kev sib pauv cua sov hauv qab - kub thiab siab - ib puag ncig siab. Seawater desalination thiab marine engineering siv lawv cov kev tiv thaiv zoo rau seawater corrosion. Kev lag luam tshuaj thiab zaub mov muaj txiaj ntsig rau nws qhov chaw du, yooj yim ntawm kev ntxuav, tsis yog - tshuaj lom, thiab ua raws li kev nyiam huv. Tsis tas li ntawd, nws tau siv dav hauv cov khoom siv kho mob (xws li cov tshuab ua kom tsis muaj menyuam thiab cov tshuab hemodialysis), hluav taws xob, khoom siv cua txias, metallurgy, tub yees, lub teeb kev lag luam, electroplating, thiab aluminium anodizing tanks, thiab lwm yam lag luam.
Thov hu rau peb yog tias koj muaj kev xav tau. Peb muab kev pabcuam zoo tshaj plaws thiab tus nqi zoo tshaj plaws.
