[Lub Ntiaj Teb Nplaim Tes] Qhov no yog qhov tsis pom qhov cuam tshuam rau qhov cuam tshuam ntawm UVLED Irradiation Effect

Tianhui tau ntsib ntau tus neeg siv khoom hauv kev sab laj. Tom qab ultraviolet UVLED lub teeb qhov chaw yog irradiated, lub nto ntawm cov kua nplaum yuav tseem xav tias nplaum. Tom qab cov kua nplaum yog nyob rau hauv kev puas tsuaj, nws pom tias cov kua nplaum yog tag nrho solidified, thiab tag nrho cov kua nplaum yog tag nrho cov kua nplaum. Tau ua lub xeev ruaj khov. Ntau tus neeg yuav nkag siab tias qhov hluav taws xob siv hluav taws xob ntawm UVLED lub teeb qhov chaw tsis txaus raws li lawv tus kheej kev nkag siab, thiab tus neeg muag khoom cov kua nplaum yuav tsis txaus raws li kev txawj ntse. Qhov no puas muaj tseeb? Qhov tseeb tsis zoo li no. Ntawm no peb yuav tsum paub qhov thaiv cov pa oxygen! Oxygen kaw kuj hu ua inhibitory inhibitory. Yuav luag tag nrho cov khoom siv hluav taws xob kho hluav taws xob hluav taws xob thiab cov khoom ua kom muaj zog yuav cuam tshuam los ntawm cov pa oxygen hauv huab cua. Vim tias qhov concentration ntawm oxygen nyob rau hauv cov txheej saum npoo yog qhov siab tshaj plaws, agglomeration ntawm oxygen feem ntau ua rau cov txheej txheem qis dua, thiab qhov saum npoo tsis khov. Qhov kev sim ua pov thawj tias rau cov kua roj vanish, lub zog siv los ntawm kev kho 1um tuab txheej hauv huab cua yog ntau tshaj li 1UM txheej txheej ntawm 1um tuab txheej hauv txheej (5um ntawm qhov chaw). Cov pa oxygen bargaining nyhuv tsis tsuas yog ncua lub sijhawm ntawm kev kho hluav taws xob, tab sis kuj tseem tuaj yeem ua rau kev ua haujlwm tseem ceeb ntawm hardness, abrasion tsis kam, thiab kev raug mob tsis kam ntawm txheej txheej, xws li hardness, abrasion resistance, thiab raug mob. Lub hauv paus xeev ntawm cov khoom siv dav dav (uas yog, lub xeev ruaj khov) yog ib-kab, tab sis tsuas yog cov pa oxygen molecules, nws lub xeev ruaj khov yog peb-kab lub xeev, thiab muaj ob qho tsis tuaj yeem ncav cuag cov khoom siv hluav taws xob hauv tib txoj kev ntawm kev tig. . Yog li, nws tuaj yeem suav hais tias cov pa oxygen molecules yog ob npaug dawb radicals. Txawm hais tias cov pa oxygen nws tus kheej yog qhov ruaj khov thiab tsis tuaj yeem ncaj qha ua rau acrylic agglomeration ntawm qhov kub thiab txias, nws yuav tawm tsam nrog cov tshuaj tiv thaiv ntawm cov dawb radicals kom haus cov dawb radicals, yog li tsim cov pa oxygen thaiv agglomeration. Muaj ntau txoj hauv kev los ua kom qeeb oxygen thaiv txoj kev. Txoj kev siv lub cev yog tshem tawm cov pa oxygen hauv cov kab ke hauv ntau txoj hauv kev, kom nws tsis tuaj yeem cuam tshuam nrog cov txheej txheem thiab txheej txheej zaj duab xis. Piv txwv li, ntawm qhov chaw nres tsheb uas raug UVLED, tshuab cov kua nplaum hauv cheeb tsam nrog nitrogen, hloov cov pa oxygen molecules ntawm cov nplaum nplaum, thiab txo cov pa oxygen thaiv kom ntau li ntau tau. Cov txheej txheem tshuaj tuaj yeem ntxiv cov tshuaj ntxuav tes xws li unusamine, sulfurlol, thiab pyrumin tebchaw hauv lub cev. Cov tshuaj no tuaj yeem siv los ua lub cev muaj zog hydrogen kom hnov ​​​​mob nrog peroxide. Los yog siv cov polymers tsawg thiab cov active diluents uas tsis tshua muaj oxygen rhiab heev, xws li active diluents thiab tsawg polymers uas muaj alpinel, propelinel, ether bonds. Cov tuam txhab ua kua nplaum zoo heev, thaum tsim cov kua nplaum, yuav xav txog qhov teeb meem ntawm kev thaiv cov pa oxygen, yog li txhawm rau ntxiv cov polymers tsim nyog thiab cov kua nplaum nquag rau cov kua nplaum. Txawm hais tias ultraviolet kua nplaum kho tshuab ua tiav, ntawm ib sab, nws nyob ntawm UVLED lub teeb qhov chaw, thiab ntawm qhov tod tes, nws nyob ntawm cov mis ntawm ultraviolet kua nplaum. Thaum ob qho tib si sib xyaw ua ke, qhov kev daws teeb meem zoo tshaj plaws yog kev siv cov phiaj xwm rau kev lag luam hauv kev lag luam.
