Daim ntawv thov cov dehumidifier hauv tshuab hluav taws xob

Nyob hauv kev tsim cov khoom hluav taws xob, vim tias cov khoom siv los yog cov khoom siv los ntub dej los mus, nws yog ib qho tseem ceeb kom tswj cov av ntawm cov cua kub kom pom tseeb thiab muaj cov khoom siv hluav taws xob. Xws li: PCB cov ntawv cog lus hauv Circuit Board, ua daim tawv cheb, optical fibers, capacitors, hluav taws xob insulators thiab lithium roj teeb. Ntawm lawv, lithium roj teeb yog ib qho ntawm feem ntau cov kev siv. Lithium roj teeb yog ib qho khoom siv sai thiab dav siv roj teeb. Lub lithium roj teeb raug muab faib ua cov roj teeb lithium thiab lub lithium roj teeb theem ob. Txij li thaum lithium yog ib qho ntawm feem ntau lub cev hlau tseem ceeb nyob hauv cov xwm txheej, nws tsis tshua muaj kev paub txog kev ya raws. Thaum cov pa lithium raug rau sab nraum zoov cua, nws yuav siv cov dej ua kua rau hauv cov cua, tso hydrogen thiab oxygen, hlawv txawm tias nyob hauv kev tawg, lithium ntsev xws li lithium cobalt oxide siv rau hauv cov roj teeb theem ob dhau heev lawm tsis tshua muaj dej noo. Yog li ntawd, txawm tias nws yog ib lub lithium roj teeb lossis ib lub roj teeb ntsuav lithium, qhov kev tswj cov av av thaum lub sij hawm cov khoom tseem ceeb heev. Kev tswj ntawm cov av noo nyob rau hauv cov txheej txheem ntawm cov roj ntsha lithium ncaj qha ntsig txog qhov zoo ntawm cov roj teeb khoom siv roj teeb. Ncaj nraim, cov chaw tsim khoom ntawm cov roj teeb lithium kuj tsis tshua muaj siab nyob rau hauv kev tswj cov av av ntawm qhov tseem ceeb ntawm nws cov khoom. Lub cev ntom ntub ntawm ib puag ncig feem ntau tswj tau hauv qab ntawm 1-2%, thiab cov dej kub nruab nrab yog qhov qis dua -320C rau -600C. Silica gel thiab molecular sieve runners feem ntau yog qhov tseem ceeb ntawm lawv cov khoom siv pov hwm ntau lawm.

Lub Plaub Hlis 24th yog lub cuaj caum "Ntiajteb Corrosion Day". Kev txhim kho qhov teeb meem yuav yog qhov chaw rau peb txhua tus, thiab nws tsis tseem ceeb. Han Enhou, tus thawj coj ntawm Lub Koom Haum Ntiaj Teb Corrosion, tus thawj coj ntawm National Metal Corrosion Control Engineering Technology Research Center, thiab tshawb fawb ntawm Lub Tsev Kawm Ntawv ntawm Kev Tshawb Fawb Hlau, Suav Academy ntawm Sciences, hais tias nyob rau hauv kev sib tham nrog central xov xwm tias corrosion los ntawm ib puag ncig kev ua pa thiab ncaj qha hem ua phem rau tib neeg txoj sia; kev qias neeg ua rau muaj kev puas tsuaj, ncaj qha Nws ua rau tib neeg muaj kev ruaj ntseg; Kev txhuam qhov teeb meem tseem ua rau kev puas tsuaj thiab tso hem thawj rau lub teb chaws Suav. Corrosion yog ib qho teeb meem tshwm sim los ntawm tag nrho cov noob neej, uas yog kev siv cov khoom siv, kev cuam tshuam ntawm ib puag ncig, thiab kev cuam tshuam rau tib neeg kev noj qab haus huv. Tag nrho cov nqi ntawm corrosion nyob rau hauv Tuam Tshoj yog kwv yees li 5% ntawm GDP, thiab corrosion nqi ntau tshaj qhov sum ntawm tag nrho ntuj tsim txom poob. Cov kev cuam tshuam los ntawm Wenchuan Av qeeg hauv xyoo 2008 yog 0.85 trillion yuan. Nyob rau hauv tib lub xyoo, Tuam Tshoj tus losses vim corrosion mus txog 1.5 trillion yuan.
