Laboratory tshuaj tiv thaiv cua sov, tshuaj extraction, khoom noj khoom haus ua thiab nplua tshuaj acidic cov hlab ntsha feem ntau yuav tsum tau cua sov Cheebtsam uas tsis txhob hlau ion nag lossis daus thiab tiv taus acidic yaig. Cov kav dej cua sov ua los ntawm 316 stainless hlau, titanium alloy thiab PFA txheej txhua qhov muaj qhov tsis zoo thaum siv rau cov xwm txheej zoo li no. Quartz cua sov raj coj siab -purity fused silica li raw khoom, featuring zoo heev acid kuj, ultra-tsis muaj impurity dissolution thiab zoo heev high -kub kuj. Txawm hais tias quartz cua sov raj tau siv dav hauv kev ua haujlwm huv thiab acidic, ntau lub Hoobkas cov kws tshaj lij thiab cov neeg yuav khoom tseem muaj kev tsis ntseeg txog lawv cov kev tiv thaiv kev cuam tshuam - muaj peev xwm cuam tshuam, kev ua haujlwm tsis zoo thiab tag nrho cov nqi nkag. Ua ke nrog lub cev thiab tshuaj lom neeg ntawm cov khoom siv quartz, cov ntaub ntawv thov hauv teb thiab ntau -index parameter piv nrog rau lwm yam peb cov khoom siv hluav taws xob, daim ntawv no txheeb xyuas cov txiaj ntsig tseem ceeb thiab txwv tsis pub siv cov kev txwv ntawm quartz los tiv thaiv -corrosion cua sov raj.
High - cov khoom siv purity quartz muaj cov tshuaj lom neeg ruaj khov heev. Nws tsis tshua muaj kev cuam tshuam nrog yuav luag tag nrho cov inorganic muaj zog acids ntawm qhov qub thiab nruab nrab- kub, thiab yuav tsis tso cov hlau impurities rau hauv cov kua ua paug cov ntaub ntawv raw. Stainless hlau cua sov raj yuav maj mam corrode thiab precipitate hlau ions nyob rau hauv kua qaub; titanium cua sov raj tuaj yeem tiv taus chloride corrosion tab sis tseem yaj cov kab mob nyob rau hauv ntev -lub sij hawm muaj zog acid soaking; PFA cladding heaters yuav muaj hnub nyoog thiab tev tawm tom qab ntev - lub sij hawm siab - siv kub, ua rau muaj kuab paug thib ob. Tsuas yog quartz cua sov raj tuaj yeem ua tiav ntev - lub sijhawm cua sov ruaj khov yam tsis muaj kev sib kis nruab nrab. Tsis tas li ntawd, quartz boasts ib qho tseem ceeb siab - kub kam rau ua, deb tshaj qhov ntev -lub sij hawm kev pab cuam qhov kub thiab txias ntawm cov hlau thiab fluoroplastic cua sov qhov chaw, thiab tuaj yeem hloov mus rau siab -kub cua kub txheej txheem uas lwm yam cua sov tsis tuaj yeem txhawb nqa.
Cov lus hauv qab no sib piv cov kev ua haujlwm tseem ceeb ntawm plaub lub hauv paus tiv thaiv- cov khoom siv cua sov:
表格
| Hom khoom siv cua sov | Acid & Alkali Resistance | Max Ntev -Lub Sijhawm Ua Haujlwm Kub | Impact & Anti-Kev sib tsoo ua haujlwm | Risk of Medium Contamination | Tag Nrho -Tus Nqi Ua Haujlwm Hauv Lub Neej |
|---|---|---|---|---|---|
| Quartz cua sov Tube | Cov kua qaub zoo heev, tsis tuaj yeem tiv taus alkali corrosion | 1180 degree | Yooj yim heev, yooj yim tawg thaum sib tsoo | Yuav luag xoom impurity nag lossis daus | Nruab nrab |
| 316 Stainless hlau cua sov Tube | Tsis muaj acid tsis kam, tsis zoo alkali tsis kam | 560 degree | Cov qauv tsim muaj zog heev | Taug qab hlau ion nag lossis daus | Tsawg |
| Ntshiab Titanium Heating Tube | Zoo acid & chloride kuj, tsis nyob rau hauv kub muaj zog alkali | 780 degree | High mechanical toughness | Tsawg impurity to | Siab |
| PFA Clad rhaub | Muaj zog tiv thaiv rau ob qho tib si acid thiab alkali | 250 degree | General, txheej khawb ua rau tsis ua hauj lwm | Zero contamination ua ntej txheej puas | Nruab nrab-High |
Nws tuaj yeem pom meej meej los ntawm kev sib piv tias quartz cua sov cov raj muaj qhov hloov pauv tsis tau nyob rau hauv siab -purity npaj thiab ntshiab acidic corrosion ib puag ncig. Nyob rau hauv cov tshuaj raw khoom synthesis thiab zaub mov brewing cov txheej txheem cua sov, stainless hlau thiab titanium cua sov raj yuav qhia hnyav hlau impurities, ua tsis tau tejyam tshuaj xyuas cov qauv; PFA cov cua sov yog txwv los ntawm qhov kub thiab tsis tuaj yeem ua tau raws li siab - qhov ntsuas kub xav tau. Quartz cua sov raj tuaj yeem ua haujlwm ruaj khov rau lub sijhawm ntev yam tsis muaj kuab paug rau kev ua haujlwm nruab nrab, txo cov khoom tsis lees paub los ntawm impurity qhia. Lub caij no, cov khoom siv quartz muaj cov hluav taws xob zoo thermal ua haujlwm, cov cua sov tsis sib xws thiab tsis tshua muaj cua sov hauv zos, uas pab txhim kho cov tshuaj tiv thaiv.
Txawm li cas los xij, cov teeb meem tuag taus txwv qhov kev nthuav dav dav ntawm quartz cua sov raj hauv txhua qhov chaw ua haujlwm. Quartz yog nkig thiab glassy, nquag tawg thiab tawg nyob rau hauv kev sib tsoo, kev co, cia li txias thiab kub alternation, ua rau cov khoom kaw thiab cov kua dej sib tsoo. Nws yog incompatible nrog tag nrho cov alkaline ua hauj lwm xov xwm, thiab alkaline kua yuav sai sai erode lub raj phab ntsa thiab ua rau kev puas tsuaj. Tsis tas li ntawd, nws qhov kev teeb tsa thiab kev thauj mus los xav tau kev tiv thaiv ntxiv, ua rau cov neeg ua haujlwm pabcuam ntxiv thiab cov nqi ntim khoom.
Txhawm rau ua kom tiav, quartz cua sov raj yog qhov kev xaiv cua sov tshaj plaws rau cov txheej txheem tsim khoom uas xav tau kev huv huv, tsis muaj kuab paug impurity thiab muaj zog acidic siab - kub cua sov. Kev txwv los ntawm kev ua tsis zoo alkali tsis kam thiab qhov nkig heev, nws tsis tuaj yeem hloov cov hlau thiab PFA cua sov raj hauv universal industrial corrosion ua haujlwm. Cov tuam txhab lag luam yuav tsum tau ua ntej quartz cua sov raj rau tshuaj, khoom noj khoom haus, chav kuaj thiab acidic siab -kub tshuaj tiv thaiv tej yaam num; rau lwm cov kev sib txuas ntau lawm uas muaj cov alkali lossis nrog kev sib tsoo tsis tu ncua, xaiv 316 stainless hlau, titanium los yog PFA cua sov raj raws li kev ua haujlwm tiag tiag thiab nyiaj txiag.
