Qhov zoo ntawm laser npav
Stainless hlau yog cov hlau uas tsis muaj zog corrosive media xws li huab cua, chav, dej thiab tshuaj lom neeg etching media xws li acids, alkalis thiab ntsev, los yog stainless acid-resistant steel. Vim nws cov weldability, kub tsis kam, corrosion kuj thiab lwm yam ntxwv, stainless hlau yog siv nyob rau hauv ib tug ntau yam ntawm daim ntaub ntawv, uas yog haum rau cov tsev kho mob los yog lwm qhov chaw uas tshwj xeeb yuav tsum tau kev tu cev, xws li: kev ua zaub mov, catering, brewing, Kev lag luam tshuaj lom neeg, thiab lwm yam. Vim tias cov hlau tsis huv yog yooj yim los ntxuav nrog dej thiab tshuaj reagents, nws tsis yooj yim rau cov kab mob.
Hauv kev xyaum, kuj tseem muaj qhov xav tau muaj zog rau cov ntaub ntawv kos npe ntawm cov hlau tsis huv, tshwj xeeb tshaj yog dub. Kev pleev xim thiab tshuaj pleev ib ce tuaj yeem pleev xim thiab zaj duab xis tom qab lub sijhawm ntev; thermal hloov npav yuav hloov xim tom qab lub sijhawm; chemical etching thiab steel marking yuav tsis ua tiav cov nyhuv dub thiab lwm yam teeb meem tshwm sim. Laser npav yog qhov tsis sib cuag, tsis muaj kev puas tsuaj rau cov khoom siv, tsis muaj tshuaj lom, muaj kev tiv thaiv ib puag ncig zoo, kos cov ntsiab lus hloov tau yooj yim, cov cim ruaj khov thiab lwm yam ntxwv, tshwj xeeb tshaj yog muaj txiaj ntsig zoo hauv kev lag luam khoom siv kho mob.
Picosecond laser: Corrosion kuj ntawm laser npav dub
Hauv kev lag luam khoom siv kho mob, kev tiv thaiv corrosion yog qhov taw qhia tseem ceeb. Cov txheej txheem ntawm kev kuaj corrosion kuj yog muab lub laser engraved hlau rau hauv ib tug tej yam concentration ntawm ntsev tsuag rau ib lub sij hawm ntawm lub sij hawm thiab ces tshem tawm nws mus soj ntsuam lub laser engraved cheeb tsam nyob rau hauv ib tug magnified yam. Tom qab qhov kev kuaj corrosion kuj, tej zaum yuav muaj teeb meem nrog lub cim tawm los yog lub laser marking cheeb tsam rusting. Txawm li cas los xij, los ntawm kev xaiv ntawm lub laser thiab kev hloov kho ntawm cov txheej txheem tsis, qhov zoo tshaj plaws cov nyhuv ntawm corrosion kuj ntawm laser dub cim yuav ua tau tiav.
Feem ntau tshwm sim li silvery dawb, stainless hlau xim los ntawm laser npav khaws nws cov khoom qub zoo, ua rau nws muaj ntau yam. Lub hauv paus ntsiab lus ntawm kev kos xim dub ntawm lub picosecond laser: lub nanostructure yog tsim los uas tsis cuam tshuam lub teeb, tsim kom pom cov nyhuv dub.
Kev kos npe nrog picosecond laser pulses tawm ib qho nyiaj txaus ntawm chromium (nyob ib ncig ntawm 20 atomic txheej) ntawm qhov chaw los hloov cov oxide zaj duab xis nrog chromium, yog li tswj kev tiv thaiv corrosion, piv txwv li hauv daim ntawv ntawm chromite lossis chromium-hlau spinel. Cov cim dub yog li ntawd qhia tias tsis muaj kev puas tsuaj los ntawm corrosion thiab nyob twj ywm kom pom tseeb txawm tias tom qab ntau, kev kuaj corrosion ntev; Thib ob, cov cim ua kom zoo, ib ntus homogeneous corrugated qauv tom qab ua tiav, uas tuaj yeem pom tau siv lub tshuab ntsuas hluav taws xob scanning raws li kev txo qis nanostructures uas ncaj qha cuam tshuam thiab tawg lub teeb los ntawm "lub teeb ntxiab nyhuv". Cov nanostructures no tau txo qis thiab cuam tshuam thiab tawg lub teeb ncaj qha los ntawm "lub teeb ntxiab nyhuv", uas ua rau muaj xim matt dub.
【Picosecond laser npav qauv】
Txij li thaum qhov kev taw qhia ntawm UDI (Unique Device Identification) tus qauv hauv Asmeskas thiab European Union, kev lag luam kho mob tau ntsib kev xav tau ntau ntxiv nyob rau hauv cov nqe lus ntawm traceability ntawm nws cov khoom. Rau kev phais stainless hlau cov ntaub ntawv nyob rau hauv kev kho mob kev lag luam, qhov no txhais tau tias tsim kom paub tseeb thiab corrosion-resistant cov cim uas nyiam dua dub nyob rau hauv cov xim thiab uas tswj lawv cov qib siab zoo nyob rau hauv lub tom ntej kev kho mob cov txheej txheem txawm tias tom qab ntau lub sij hawm tu thiab tshuaj tua kab mob.
Cov cim dub siv picosecond pulsed lasers yog qhov zoo tshaj plaws rau kev tsim cov matte dub, cov cim tiv thaiv corrosion uas yuav nyob ruaj khov thiab meej rau lub sijhawm ntev hauv kev kho mob.
Lub picosecond laser yog cim nyob rau hauv cov xim dub ntawm cov kev kho mob phais forceps thiab nyob rau hauv lub ablation koob raws li qhia hauv qab no.
Nyob rau hauv daim ntawv thov scenario ntawm stainless hlau dub cim nrog siab xav tau thiab cov txheej txheem loj thov, laser txheej txheem tau maj mam hloov cov tsoos cim txheej txheem, thiaj li yuav tau txais kev ruaj ntseg zoo, nyob rau hauv ib tug ntau yam ntawm kev sim, kev siv picosecond pulse laser rau stainless steel nto dub marking yog tam sim no qhov kev xaiv zoo dua nyob rau hauv kev ua lag luam, UDI kos npe twb yog ib daim ntawv thov paub tab, tab sis nyob rau hauv lub neej yav tom ntej nrog kev thov nce, nws ntseeg hais tias laser technology nrog nws tshwj xeeb kev ua tau zoo thiab high efficiency yuav muaj ntau yam kev loj hlob. kev siv hauv kev kho mob kev lag luam.
