Lub teeb pom kev photocatalysis yog dab tsi?
Pom pom lub teeb photocatalysis yog hais txog photocatalytic oxidation thiab degradation ntawm photocatalyst nyob rau hauv cov teeb pom kev zoo.
Lub hauv paus ntsiab lus ntawm pom lub teeb photocatalysis yog dab tsi?
Pom pom lub teeb catalytic yog raws li pom lub teeb irradiation lub teeb catalyst, catalyst valence band ntawm lub teeb hauv av xeev electron hloov mus rau conduction band, tsim lub teeb yug lub qhov thiab lub teeb hluav taws xob, lub teeb lub qhov nrog cov dej molecules los tsim hydroxyl dawb radicals, electrons thiab oxygen molecule cov tshuaj tiv thaiv tsim super oxygen anion, thiab qhov, hydroxyl radicals thiab superoxide anion ntau lawm, Reactive oxygen hom tuaj yeem degrade tsw molecules, organic teeb meem, kab mob thiab lwm yam kuab paug rau hauv dej thiab carbon dioxide thiab lwm yam me me molecules.Ib qho me me ntawm N, S thiab P hauv cov organic teeb meem yuav tsim cov nitrate, sulfate, phosphate thiab lwm yam tom qab degradation, thiaj li ua si detoxification, deodorization thiab sterilization nyhuv.Pom pom lub teeb photocatalytic txheej tshuab muab cov tshuaj ntsuab tshiab rau kev kho cua hauv tsev thiab sab nraum zoov.
Vim li cas thiaj siv pom lub teeb photocatalysis?
Raws li cov lus piav qhia nyob rau hauv lub teb chaws tus qauv GB / T 17683.1-1999, lub teeb ultraviolet nyob rau hauv lub hnub tsuas yog 7%, lub teeb pom kev rau 71%, thiab infrared account rau 22%.Txawm hais tias lub zog ntawm ultraviolet photon loj dua qhov pom lub teeb lossis lub teeb infrared, lub teeb pom kev thiab lub teeb infrared "yeej" los ntawm tus lej.Tsoos photocatalytic oxidation tshuab tsuas yog nyob rau hauv qhov kev txiav txim ntawm ultraviolet lub teeb oxidation degradation ntawm organic pollutants.Thiab Jiangyin hnub xeev quantum txheej technology co., LTD.Cov khoom lag luam pom lub teeb catalytic oxidation thev naus laus zis thiab quantum theem TiO2, nws txoj haujlwm tuaj yeem tshwm sim tsis tau tsuas yog nyob rau hauv lub teeb pom kev photocatalytic oxidation degradation, tab sis kuj tuaj yeem catalytic oxidation degradation nyob rau hauv ultraviolet thiab infrared lub teeb cov tshuaj tiv thaiv, nws yog ib tug tshiab tag nrho spectrum teb ntawm lub photocatalytic technology, zoo heev txhim kho cov efficiency.
