Vim li cas Sulfinert Finish Stainless Instrumentation Tube Matters hauv Kev Tshawb Fawb?

Hauv kev tshuaj ntsuam xyuas, cov qauv kev ruaj ntseg thiab kev ncaj ncees ncaj qha txiav txim siab cov ntaub ntawv kev ntseeg siab. Txawm li cas los xij, cov kab hloov pauv tsis tau kho feem ntau adsorb lossis catalytically decompose cov kab mob nquag, ua rau muaj teeb meem loj.

Sulfinert tiav stainless hlau instrumentation tubing zoo tiv thaiv cov adsorption thiab cov tshuaj tiv thaiv ntawm cov tshuaj nquag -xws li sulfur compounds thiab mercury- los ntawm kev tsim cov tshuaj tiv thaiv tsis zoo rau ntawm phab ntsa sab hauv, yog li kev kov yeej qhov tsis zoo ntawm cov khoom siv tsis zoo stainless hlau tubing.

Piv nrog rau cov pa raj, Sulfinert tiav tubing muaj kev sib xyaw ua ke ntawm cov tshuaj lom neeg zoo tshaj plaws thiab cov khoom siv ua haujlwm ntev, ua rau nws tsim nyog rau cov ntawv thov tseem ceeb xws li roj chromatography, kev saib xyuas ib puag ncig, thiab kev tshawb fawb roj.

Sulfinert Finish yog dab tsi?

Cov txheej txheej Sulfinert (tseem hu ua SilcoNert® 2000) yog qhov siab -kev ua tau zoo, silicon-raws li inert txheej uas ua los ntawm cov tshuaj vapor deposition (CVD) technology. Nws hloov pauv cov khoom siv tshuaj lom neeg ntawm cov hlau los ntawm kev tsim cov khoom sib xws, tsis yog - ntxeem tau, thiab cov tshuaj sib xyaw ua ke ntawm amorphous silicon. Ntsuas tsuas yog ntau pua nanometers nyob rau hauv tuab, cov txheej txheem no npog tag nrho cov chaw ua haujlwm ntawm cov hlau tsis huv, thaiv kev sib cuag ntawm cov qauv molecules thiab cov hlau substrate.

Tsis zoo li cov txheej txheem passivation cov qauv, cov txheej txheem Sulfinert txheej siv siab -kub CVD kom diffuse silicon atoms sib sib zog nqus mus rau hauv cov siv lead ua lattice ntawm stainless hlau substrate, tsim ib tug metallurgical - qib tshuaj daim ntawv cog lus. Qhov no ua kom cov txheej txheem yuav tsis flake, tawg, los yog delaminate, tuav nws txoj kev tiv thaiv kev ncaj ncees txawm tias nyob rau hauv cov xwm txheej uas muaj feem ntau ntawm cov tubing dabtsi yog khoov, siab - siab surges, los yog thermal cycling.

Inertness thiab Durability Properties

Cov txiaj ntsig tseem ceeb ntawm Sulfinert tiav nyob rau hauv nws cov tshuaj lom neeg tshwj xeeb inertness thiab zoo heev mechanical durability. Hais txog inertness, txheej txheej nta tsis tshua muaj zog saum npoo, ua rau tsis muaj adsorption ntawm polar, reactive compounds xws li hydrogen sulfide, mercaptans, thiab carbonyl sulfide.

Nyob rau hauv cov nqe lus ntawm durability, lub Sulfinert txheej ho ua tau zoo tshaj cov tsoos PTFE txheej los yog silanization kev kho mob. Nws tiv taus kev khiav hauj lwm kub txog li 450℃thiab tiv thaiv degradation los ntawm feem ntau cov organic solvents, acids, bases, thiab corrosive gases.

Adsorption thiab Sample Poob

Tsis kho cov hlau tsis huv yog nplua nuj nyob rau hauv cov hlau oxides thiab Lewis acid qhov chaw, nthuav tawm lub cev muaj zog lossis tshuaj lom neeg adsorption mus rau cov polar molecules, thiols, hydrogen sulfide, thiab mercury vapor. Hauv kev soj ntsuam kab, qhov no ua rau cov qauv tsis tu ncua raws li txoj hauv kev los ntawm qhov nkag mus rau qhov ntsuas, ncaj qha ua rau txo qis qhov chaw siab tshaj, nce siab kom pom kev txwv, thiab txawm tias cov teeb meem xws li ncov tailing thiab dab peaks, yog li cuam tshuam ntau qhov tseeb.
 

Kev pheej hmoo kis kab mob

Tshaj li cov qauv poob vim adsorption, tsis kho stainless hlau tubing ua rau muaj kev phom sij ntau yam kab mob. Ua ntej, hlau ions-xws li hlau, npib tsib xee, thiab chromium- tuaj yeem tawm los ntawm cov hlau tsis huv mus rau hauv cov qauv ntws hauv qee qhov xwm txheej, ua rau cov hlau tsis huv uas cuam tshuam nrog cov txheej txheem qis qis xws li spectroscopic tsom xam thiab huab hwm coj spectrometry. Thib ob, oxide txheej thiab cov khoom siv corrosion ntawm cov phab ntsa sab hauv ntawm lub raj tuaj yeem flake tawm los ua cov khoom seem, muaj feem cuam tshuam cov kab chromatographic kab lossis cov khoom puas.

Thaum txheeb xyuas cov tshuaj reactive, cov khoom siv tsis zoo stainless hlau tuaj yeem ua raws li cov khoom siv hluav taws xob, txhawb cov qauv decomposition lossis kev hloov pauv. Piv txwv li, qee qhov thiols yuav raug dimerization ntawm cov hlau nto los ua cov disulfides; Qhov no hloov pauv cov qauv muaj pes tsawg leeg, ua rau cov txiaj ntsig analytical tsis sawv cev ntawm tus qauv qhov tseeb lub xeev. Qhov no catalytic nyhuv yog ntxiv intensified ntawm qhov kub thiab txias, ho limiting lub applicability ntawm txoj kev tshuaj ntsuam.

Tiv thaiv adsorption thiab tshuaj tiv thaiv

Sulfinert txheej hauv paus daws teeb meem ntsig txog adsorption thiab reactivity los ntawm kev tsim kom tiav, inert barrier ntawm stainless hlau nto. Qhov no tso cai rau polar, sulfur- muaj, thiab tsis ruaj khov cov tebchaw kom dhau mus yam tsis muaj adsorption lossis catalytic decomposition. Txawm hais tias cuam tshuam nrog cov kab mob formaldehyde, reactive sulfides, los yog labile mercury hom, cov analytes tseem zoo li thaum sib cuag nrog cov phab ntsa tubing, yog li tshem tawm cov kev hloov pauv uas tshwm sim los ntawm lub raj nws tus kheej.

Txhim kho rov qab thiab ruaj khov rau Sulfur Compounds

Ib qho tseem ceeb daim ntawv thov cheeb tsam rau Sulfinert coatings yog tsom xam ntawm sulfur compounds. Cov kev tshawb fawb sib piv dav dav tau lees paub tias, hauv matrices xws li cov nkev, roj refinery, thiab huab cua nyob ib puag ncig, Sulfinert-coated stainless hlau ntsuas tubing muab kev txhim kho tseem ceeb hauv ob qho tib si kev rov qab los thiab kev ruaj ntseg ntawm ntau hom sulfur.

Ntxiv nrog rau kev txhim kho tus nqi rov qab, kev kho mob Sulfinert tau txhim kho kev ruaj khov ntawm cov tshuaj sulfur. Coated sampling cylinders thiab cov kab hloov pauv khaws cia qhov tseem ceeb ntawm cov qauv rau lub sijhawm ntev, yog li so lub sijhawm txwv ntawm kev kuaj thiab tshuaj xyuas.

Siv Cases hauv Kev Tshawb Fawb Kev Lag Luam

Lub Sulfinert Finish Stainless Instrumentation Tube tau dav siv nyob rau hauv ntau qhov kev tshuaj ntsuam xyuas.This sulfonated tubing yog tsim rau ntau qhov chaw soj ntsuam uas xav tau cov qauv nruj nruj. Cov ntawv thov uas muaj xws li:

• Kev tshuaj xyuas sulfur hauv cov nkev thiab petrochemical kwj
• Mercury saib xyuas
• Kev kuaj Environmental emissions
• Laboratory gas sampling
• Siab -kev soj ntsuam cov txheej txheem purity
• Refineries thiab downstream zog systems
• Tshwj xeeb gas xa thiab kab impurity tsom xam

Specification thiab Integrating Sulfinert Tubing

Thaum qhia txog Sulfinert-kho tubing, cov neeg tsim qauv yuav tsum xav txog ntau dua li cov tubing qhov ntev thiab qib stainless hlau; lawv kuj yuav tsum tau soj ntsuam lwm yam.

Cov khoom siv feem ntau suav nrog 316L thiab 304 stainless hlau, nrog cov kab uas feem ntau yog li ntawm 1/16 nti mus rau 1/2 nti. Seamless tubing nrog cov phab ntsa tuab yuav tsum tau xaiv rau siab - cov ntawv thov siab, thaum annealed (mos- temper) tubing yog tsim rau kev teeb tsa uas yuav tsum tau khoov ntau zaus. Lub hauv paus ntsiab lus tseem ceeb yog tias tag nrho cov qauv ntws mus rau-xws li tubing, fittings, li qub, lim, thiab tag nrho lwm yam wetted Cheebtsam -yuav tsum tau txais kev kho mob Sulfinert kom tsis txhob muaj "kev sib txuas tsis muaj zog tshaj".

Hauv cov ntsiab lus, Sulfinert-coated stainless steel instrumentation tubing plays lub luag haujlwm tseem ceeb hauv kev tswj xyuas kev ncaj ncees ntawm cov qauv siv tshuaj thiab qhov tseeb ntawm cov ntaub ntawv txheeb xyuas. Hais txog kev ua tau zoo, Sulfinert kev kho mob tsis tsuas yog txhim kho cov ntaub ntawv raug thiab rov tsim dua tshiab tab sis kuj tseem txuas ntxiv kev pabcuam lub neej thiab txo cov nqi kho, muab cov nqi sib tw uas deb tshaj li cov tsoos, tsis kho tubing.

Rau ib qho chaw kuaj lossis cov txheej txheem kev lag luam saib xyuas qhov tseem ceeb ntawm kev txheeb xyuas cov ntaub ntawv kev ntseeg tau, kev siv tshuab Sulfinert txheej yuav tsum tau suav tias yog ib qho tseem ceeb ntawm kev ntsuas kev ruaj ntseg.
