Glow sticks tau yog ib qho tseem ceeb ntawm Halloween txij thaum nws pib. Lawv yog cov zoo tagnrho raws li kev nyab xeeb teeb vim rau lawv portability, affordability, thiab ethereal luminescence.Lub teeb sticks, feem ntau raug xa mus rau qee tus, muaj ntau yam nyob rau hauv kab lis kev cai rave, nrog rau lub teeb caj dab, lub teeb tsom iav, thiab lub teeb hlua. Lawv ua lub teeb pom kev zoo rau SCUBA divers thiab campers.
Dab tsi yog qhov mechanism tom qab kev ua haujlwm ntawm glow sticks? Cov thev naus laus zis hauv qab glow sticks, txawm hais tias nws yuav zoo li yog supernatural, yog qhov yooj yim. Cia peb kuaj xyuas sab hauv ntawm lub teeb pom kev pom tias nws tawm lub teeb hnyav li cas yam tsis muaj lub teeb lossis roj teeb.
Teebyog hom hluav taws xob uas tuaj yeem tsim los ntawm ntau txoj hauv kev.
Cov txheej txheem hauv qab no suav nrog:
Incandescence: Lubkev tsim lub teebuas tshwm sim los ntawm thermal zog, raws li pom nyob rau hauv ib tug pa lub teeb los yog roj teeb.
Fluorescence thiab phosphorescence: Lub emission ntawm lub teeb uas tshwm sim los ntawm hluav taws xob hluav taws xob, raws li pom nyob rau hauv fluorescent teeb los yog TV.
Laser tiam: Lub tsom emission ntawm lub teeb los ntawm stimulated emission
Tag nrho cov txheej txheem no ua haujlwm ntawm tib lub hauv paus ntsiab lus: lub zog sab nraud txhawb nqa atoms, ua rau lub teeb pom kev zoo hu ua photons. Thaum combustion tshwm sim, thermal zog accelerates lub atoms constituting cov khoom. Raws li cov atoms nrawm, lawv sib tsoo nrog ib leeg nrog kev siv zog ntxiv.
Thaum cov atoms txaus siab txaus, kev sib tsoo yuav muab lub zog rau qee cov electrons ntawm atom. Hauv qhov xwm txheej zoo li no, ib qho hluav taws xob yuav raug nce mus rau lub zog siab dua, nyob deb ntawm lub nucleus ntawm lub atom. Thaum nws thiaj li poob rov qab mus rau nws qib qub (ze rau lub nucleus), nws tso tawm qee qhov ntawm nws lub zog nyob rau hauv daim ntawv ntawm lub teeb photons.
Lub glow stick ua tib yam yooj yim, tab sis nws siv cov tshuaj tiv thaiv kom zoo siab rau cov atoms.
Cov tshuaj tiv thaiv
Lub teeb stickstuaj nyob rau hauv ntau yam xim. Cov xim ntawm lub teeb yog dictated los ntawm cov tshuaj pleev ib ce ntawm fluorescent dye nyob rau hauv tus pas.
Lub teeb sticks siv lub zog los ntawm cov txheej txheem tshuaj los tawm lub teeb. Cov tshuaj tiv thaiv tshuaj no yog teem tawm los ntawm kev sib txuas ntau yam tshuaj lom neeg. Compounds yog cov tebchaw ua los ntawm cov atoms ntawm cov ntsiab lus sib txawv, txuas ua ke hauv cov qauv khoom. Thaum koj sib tov ob lossis ntau lub tebchaw, cov atoms sib txawv tuaj yeem hloov kho lawv tus kheej los tsim cov tebchaw tshiab. Nyob ntawm qhov xwm txheej ntawm cov molecules, qhov tshuaj tiv thaiv no yuav ua rau muaj kev tso tawm ntawm lub zog los yog nqus lub zog.
Cov tshuaj tiv thaiv ntawm ntau yam tshuaj nyob rau hauv ib lub teeb stick tsim ib tug txiav txim siab tso tawm ntawm lub zog. Ib yam li hauv lub teeb pom kev zoo, cov atoms hauv cov ntaub ntawv raug txhawb, ua rau cov hluav taws xob nce mus rau qib siab zog thiab rov qab mus rau lawv cov qib qub. Thaum rov qab mus rau lawv lub xeev hauv av, electrons emit zog nyob rau hauv daim ntawv ntawm lub teeb. Qhov no tshwm sim yog hu ua chemiluminescence.
Cov txheej txheem
Cov txheej txheem tshuaj ntawm cov nplaum nplaum feem ntau muaj ntau theem sib txawv. Tus qauv coj mus muaglub teebmuaj cov tshuaj hydrogen peroxide, phenyl oxalate ester tov, thiab fluorescent zas xim. Cov hauv qab no qhia txog qhov sib lawv liag ntawm cov xwm txheej raws li kev sib koom ua ke ntawm ob txoj kev daws teeb meem:
Hydrogen peroxide oxidises phenyl oxalate ester, yielding phenol thiab ib qho tsis ruaj khov peroxy acid ester.
Qhov tsis ruaj tsis khov peroxy acid ester dhau mus decomposition, yielding ntau phenol thiab cyclic peroxy molecule.
Lub cyclic peroxy molecule undergoes decomposition kom tawm carbon dioxide.
Qhov kev tawg no tso tawm lub zog rau cov xim.
Cov electrons hauv cov xim atoms nce mus rau lub zog siab zog thiab tom qab ntawd nqis, emitting zog li lub teeb.
Cov nplaum nplaum ua haujlwm tsuas yog lub thawv rau ob lub kua uas koom nrog cov tshuaj tiv thaiv - hauv paus, nws yog kev sim tshuaj mobile.
Lub Luminescent Stick Catalyst - Hydrogen Peroxide
Cov nplaum nplaum muaj ib lub khob iav nqa ib qho tshuaj tov, ntim rau hauv lub raj yas loj dua uas muaj cov tshuaj sib txawv. Thaum khoov cov yas vial, iav vial shatters, uas ua rau kev sib xyaw ntawm ob txoj kev daws teeb meem. Cov txheej txheem tshuaj ua kom muaj fluorescent dye uas emits lub teeb.
Glow stick muaj ob txoj kev daws teeb meem uas emit lub teeb thaum ua ke. Ua ntej yuav ua kom lub teeb nplaum, ob txoj kev daws teeb meem yog khaws cia hauv cov chav sib txawv. Cov phenyl oxalate ester thiab cov tshuaj zas xim occupies feem ntau ntawm cov yas lo. Cov tshuaj hydrogen peroxide, hu ua tus activator, yog nyob rau hauv ib lub me me, mos iav vial nyob rau hauv nruab nrab ntawm tus pas.
Thaum khoov tus pas yas, lub khob vial tawg, tso cai rau ob lub kua sib xyaw ua ke. Cov tshuaj tam sim ntawd cuam tshuam, ua rau cov atoms tso lub teeb. Cov xim tshwj xeeb ua haujlwm hauv cov tshuaj lom neeg ua rau lub ntsej muag tshwj xeeb rau lub teeb.
Lub sijhawm ntawm cov tshuaj tiv thaiv tshuaj yuav nyob ntawm ob peb feeb mus rau ntau teev, cuam tshuam rau cov khoom siv. Cua sov cov kua yuav ua rau kom cov tshuaj tiv thaiv, ua rau tus pas emit ib lub teeb ci, tab sis rau lub sij hawm txo. Txias lub teeb stick yuav decelerate cov tshuaj tiv thaiv, ua rau tsawg luminosity. Txhawm rau ncua lub neej ntawm koj lub teeb rau hnub tom ntej, muab tso rau hauv lub tub yees; thaum qhov no yuav tsis txwv cov tshuaj tiv thaiv, nws yuav ncua nws txoj kev loj hlob.
Ua kom sov alub teebyuav ua kom ceev cov txheej txheem tshuaj, uas ua rau muaj kev mob siab ntxiv luminescence los ntawm cov dye. Lub teeb stick ntawm sab laug tau qhib thiab khaws cia ntawm qhov kub thiab txias.
Glow sticks ua piv txwv txog qhov tseem ceeb ntawm ntuj tsim lub npe hu ua luminescence. Luminescence yog hais txog txhua lub teeb emission uas tshwm sim yam tsis muaj kev cuam tshuam ntawm thermal excitation. Luminescence yog siv hauv TV, teeb neon, thiab ci ntsa iab-hauv-- cov ntawv nplaum tsaus. Nws kuj yog lub hauv paus ntsiab lus uas illuminates ib tug firefly thiab ua rau tej pob zeb kom emit lub teeb nyob rau hauv qhov tsaus ntuj nti.
Shenzhen Benwei Teeb pom kev zoo Technology Co., Ltd tau tsim nyob rau hauv 2010. Nws yog lub teb chaws siab -tech enterprise integrating tsim, R & D, ntau lawm thiab muag khoom ntawm sab hauv thiab sab nraum zoov teeb pom kev zoo khoom thiab kuj yuav ua tau OEM, ODM .Yog xav paub ntxiv txog peb cov khoom, thov hu rau peb ntawmbwzm18@ledbenweilighting.com
