Kev sim hauv chav kuaj, kev npaj tshuaj reagent thiab cov khoom siv tshuaj pleev ib ce kom zoo nkauj ua kom nruj heev rau cov khoom siv cua sov. Txawm tias me me hlau ion dissolution yuav hloov qhov muaj pes tsawg leeg ntawm cov qauv thiab cov khoom tiav, ua rau cov kev sim ua tsis tiav los yog cov khoom tsis tsim nyog. Hlau cua sov raj xws li 316 stainless hlau thiab titanium inevitably muaj kev pheej hmoo ntawm cov kab hlau los nag tom qab ntev - lub sij hawm cua sov, thaum PFA txheej yuav tso cov khoom zoo polymer hauv qab kub. Quartz cua sov raj ua los ntawm fused silica tshwm sim ua pa phem -dawb cua sov tov. Txawm li cas los xij, ntau tus kws tshawb fawb thiab cov kws tshaj lij tsim khoom tseem xav tsis thoob tias cov raj cua sov quartz tuaj yeem sib npaug los tiv thaiv - muaj peev xwm corrosion thiab cov khoom siv ua haujlwm ntev, thiab dab tsi cuam tshuam nws qhov loj - nplai daim ntawv thov hauv kev tsim khoom hnyav. Kab lus no piav qhia txog nws cov yam ntxwv ntawm cov khoom siv, qhov tshwj xeeb muaj zog thiab qhov tsis zoo ntawm lub hauv paus nrog cov lus sib piv kom ntxaws.
Quartz yog tsim los ntawm ze li ntawm cov ntshiab silicon dioxide, ib qho tshuaj inert inorganic khoom uas tsis tshua muaj tshwm sim nrog feem ntau inorganic acids, organic solvents thiab oxidizing cov neeg ua hauj nyob rau hauv nws muaj kev nyab xeeb ua hauj lwm kub. Tsis zoo li cov hlau cua sov cov raj uas tso siab rau cov yeeb yaj kiab uas siv tau los tiv thaiv- tiv thaiv corrosion, quartz nws tus kheej yuav tsis yaj cov khoom siv hlau rau hauv cov kua rhuab, tshem tawm cov kab mob nruab nrab. Ntxiv mus, quartz feem ntau hloov cov cua sov los ntawm cov hluav taws xob infrared es tsis yog kev sib cuag ncaj qha, uas txo cov cua sov hauv zos thiab tsis txhob cuam tshuam cov tshuaj lom neeg ntawm cov rhiab heev reagents. Nws qhov siab tshaj plaws ntev -lub sijhawm kev pabcuam kub tuaj yeem ncav cuag 1200 degree, deb tshaj qhov ntsuas kub ntawm stainless hlau, titanium thiab PFA cov khoom siv cua sov, ua rau nws muaj feem xyuam rau cov txheej txheem kub ntawm - kub thiab ziab. Cov lus hauv qab no sib piv cov yam ntxwv tseem ceeb ntawm plaub yam kev tiv thaiv -corrosion cua sov Cheebtsam.

Los ntawm cov ntaub ntawv cov lus, qhov zoo tshaj plaws irreplaceable ntawm quartz cua sov raj yog nyob rau hauv kiag li tsis muaj - paug thiab ultra- kub kuj. Hauv kev sim tshuaj lom neeg thiab tshuaj txhaj tshuaj, cov khoom lag luam purity yog thawj tus qauv ntsuas. Stainless hlau thiab titanium cua sov raj yuav maj mam tso tawm cov hlau tsis huv tom qab lub hlis ntawm kev tso dej, thaum PFA cov ntaub ntawv tuaj yeem decompose me ntsis hauv qab kub kub. Tsuas yog quartz tuaj yeem tswj hwm tus thawj muaj pes tsawg leeg ntawm cov cua sov nruab nrab stably. Tsis tas li ntawd, limescale thiab chemical residues yog ib qho nyuaj rau ua raws li nruj nreem quartz nto, yog li kev saib xyuas txhua hnub tsuas yog yuav tsum tau yooj yim so tsis tu ncua descaling thiab tiv thaiv - kho corrosion.
Txawm li cas los xij, kev tuag brittleness zoo heev txwv kev nce qib ntawm quartz cua sov raj hauv cov kab txuas txuas txuas ntxiv. Sudden dej txias txaws ntawm kub quartz raj, me ntsis kev sib tsoo thaum lub sij hawm installation thiab kev thauj mus los, los yog tsis tsim nyog clamping yuav ncaj qha ua rau tawg thiab rupture, ua rau cov kua to thiab cov cuab yeej nres. Dhau li ntawd, siab -concentration kub sodium hydroxide thiab lwm yam muaj zog alkaline daws yuav maj mam corrode silica molecular qauv, thinning lub raj phab ntsa thiab nws thiaj li ua rau perforation puas. Piv nrog rau cov kav hlau cua sov uas tuaj yeem tiv taus kev sib tsoo ntau zaus thiab cov khoom siv tshuab, cov khoom siv quartz muaj qhov hloov pauv ntau dua hauv qhov chaw tsim khoom.
Hauv kev xaus, quartz los tiv thaiv- cov kav dej cua sov yog qhov kev xaiv zoo tshaj plaws rau kev sim thiab tshuaj cua sov uas txwv tsis pub muaj kuab paug tsis huv thiab xav tau kev kub siab -. Kev txwv los ntawm cov neeg kho tshuab poob siab tsis zoo thiab tsis kam ua rau muaj zog alkali, nws tsis tuaj yeem hloov cov hlau thiab fluoroplastic cua sov cov cuab yeej hauv loj - cov chaw tsim tshuaj lom neeg nrog rau kev ua haujlwm hnyav. Cov neeg siv yuav tsum xaiv quartz cua sov raj tsuas yog thaum reagent purity thiab siab - qhov xav tau qhov kub thiab txias yog qhov tseem ceeb tshaj qhov ua haujlwm ntev.
