RANA Lined PTFE High-Purity Electronic-Qib Sulfuric Acid Storage Tank Ua Tau Raws Li Lub Tebchaws G5 Daim Ntawv Pov Thawj

Lub tank txais cov qauv sib xyaw ntawm 304 stainless hlau plhaub + siab -purity PTFE hauv ob sab phlu, thiab tshwj xeeb tshaj yog optimized rau lub zog corrosiveness thiab siab -purity yuav tsum tau ntawm hluav taws xob- qib sulfuric acid:

Ultra-huv los tiv thaiv-corrosion system: PTFE hauv ob sab phlu yog cov kws tshaj lij pretreated los txhim kho lub zog sib txuas nrog 304 steel plhaub, tuaj yeem tiv taus ntev -lub sij hawm immersion hauv hluav taws xob- qib sulfuric acid, thiab cov hlau ion nag lossis daus yog<0.5ppb, which is far better than the 1ppb limit of the national G5 standard. The smooth and non-stick property of PTFE can greatly reduce medium adsorption and residue.

Precision welding txheej txheem: Lub tank hauv ob sab phlu txais cov txheej txheem tsis siv neeg orbital PFA vuam, nrog du thiab tiaj welds, tsis muaj qhov tsis xws luag xws li vuam slag thiab pores. Cov txheej txheem vuam siv inert gas tiv thaiv kom tsis txhob impurity tiam los ntawm siab - kub decomposition ntawm PTFE cov ntaub ntawv; cov welds raug soj ntsuam los ntawm cov hluav taws xob xau nrog 0 tus nqi xau, ua kom tsis muaj kuab paug ntawm qhov nruab nrab khaws cia.

Kev ua haujlwm ruaj khov nyob rau hauv ntau qhov kub thiab txias: Nws tuaj yeem ua haujlwm tau ntev hauv qhov kub ntawm -40℃txog 120 degree, ua tau raws li qhov xav tau ntawm qhov kub thiab txias cia hauv cov txheej txheem ntawm cov khoom siv hluav taws xob. Lub tank yog tsim los nrog cov qauv siv zog ntxiv, thiab nws cov kev cuam tshuam tsis zoo tuaj yeem txhim kho los ntawm 30%, uas tuaj yeem hloov mus rau qhov chaw ua haujlwm nyuaj.

Tam sim no, cov khoom no tau ua tiav hauv kev ua haujlwm siab -purity reagent rhiav ntawm zoo-cov tuam txhab paub xws li SMIC thiab TCL Huaxing, rau khaws cov ntaub ntawv tseem ceeb xws li sulfuric acid rau wafer tu thiab etching tov rau photovoltaic hlwb. Hauv kev tsim khoom tiag tiag, lub tank tau ua haujlwm tsis tu ncua rau 12 lub hlis tsis muaj corrosion thiab to, ua kom muaj kev ruaj ntseg ntawm cov txheej txheem ntau lawm thiab cov khoom tawm los.

Tus thawj coj ntawm RANA tau hais tias raws li cov khoom lag luam tank uas tau dhau lub teb chaws G5 tus qauv hauv Suav teb, nws yuav txuas ntxiv txhawb kev hloov pauv hauv cheeb tsam ntawm cov khoom siv tshuaj lom neeg thiab ua rau muaj kev nyab xeeb ntawm kuv lub teb chaws siab - kawg kev lag luam saw hlau.
