High -cov qauv ntsuas kub rau kev txheeb xyuas cov ntsiab lus, kev kho cov kua qaub ntawm cov khoom siv semiconductor precision, thermal leaching ntawm cov pob zeb hauv av tsis tshua muaj cov peev txheej thiab cov thermal ua ntawm refractory ores ua nruj me ntsis rau cov khoom siv cua sov ua haujlwm hauv boiling concentrated mineral acid ib puag ncig. Cov khoom siv hluav taws xob ua kom sov, suav nrog molybdenum-doped 316L stainless hlau thiab kub-forged titanium, tso siab rau nyias oxide passive films los tiv thaiv kev tawm tsam. Cov khaubncaws sab nraud povtseg no ua rau muaj tshuaj lom neeg tsis tu ncua nyob rau hauv ntev -lub sij hawm siab-kub acid raug, ua rau sheath thinning thiab paug cov txheej txheem kua. Kev txwv los ntawm kev txwv kev laus thermal, cov khoom siv polymer-clad cua sov tsis tuaj yeem ua kom muaj kev kub ntxhov siab ntxiv - cov txheej txheem acid acid. Fabricated los ntawm siab -purity fused silica, cov cua kub ntxig NW nyuam qhuav hnov mob nrog sulfuric acid, hydrochloric acid thiab phosphoric acid nyob rau hauv fluoride- tej yam kev mob dawb. Lawv nyob rau hauv ib pawg me me ntawm cov khoom siv engineering uas muaj peev xwm ua kom ntev ntev - lub sijhawm cua sov zoo li qub nyob rau hauv ultra- siab - kub muaj zog acid ua haujlwm. Daim ntawv no qhia txog nws qhov kev ua haujlwm tsis zoo hauv kev tiv thaiv- cov yam ntxwv corrosion, kev siv tau zoo, cov khoom txwv thiab txwv tsis pub ua haujlwm. Muaj ntau-qhov kev sib piv ntawm qhov sib piv ntawm plaub lub ntsiab hluav taws xob cua sov ntxig rau qhov siab zoo li qub- kub muaj zog acid ib puag ncig yog muab.
1. Core Inert Properties thiab Cov Ntawv Thov Tshwj Xeeb Zoo
Nyob rau hauv fluoride-dawb muaj zog acid media, fused silica tswj cov tshuaj zoo heev. Nws cov txheej txheem covalent tsis nruj tiv thaiv matrix dissolution thiab tsis txhob tso impurity ions thaum lub sij hawm ntev cua sov hauv boiling acid. Tsis zoo li cov cua sov hlau tiv thaiv los ntawm cov yeeb yaj kiab tsis zoo, fused silica ua tiav cov kua dej purity tswj los ntawm cov tshuaj inertness inertness, zoo tiv thaiv cov hlau ion leaching uas cuam tshuam nrog cov qauv tshuaj ntsuam xyuas thiab cov txheej txheem ua kua. Cov ntaub ntawv muaj ib qho ultra-tsis tshua muaj thermal expansion coefficient thiab zoo heev thermal shock resistance, tiv thaiv tawg nyob rau hauv qhov kub thiab txias hloov, nrog rau qhov siab tshaj plaws kev pab cuam kub kub mus txog 1180 degree. Tau txais txiaj ntsig los ntawm kev xa tawm lub teeb pom kev zoo, cov khoom siv cua sov txhawb nqa ultraviolet-pab photothermal cua sov, muaj nuj nqi tshwj xeeb tsis muaj nyob rau hauv cov hlau thiab fluoroplastic cua sov sib dhos.

3. Cov khoom siv tsis txaus thiab txwv kev pabcuam
Fused silica cua sov inserts muaj qhov pom tseeb qhov tsis muaj zog. Hydrofluoric acid thiab siab -kub alkaline daws ua rau muaj kev puas tsuaj tshuaj lom neeg nrog silica substrates. Yog li ntawd, tag nrho cov nruab nrab nruab nrab uas muaj alkali los yog fluoride tebchaw yog nruj me ntsis txwv tsis pub. Cov khoom muaj qhov tseem ceeb brittleness; kev sib tsoo lub cev, nplawm- ua rau muaj kuab paug thiab kev co tsis tu ncua yooj yim ua rau tawg. Tsawg thermal conductivity ua rau qeeb qhov kub thiab txias tsis sib xws, ua rau nws tsis tsim nyog rau cov kua dej ntws tawm. Tsis tas li ntawd, kev puas tsuaj silica inserts tsis tuaj yeem kho tau, thiab kev ua haujlwm siab precision ua rau cov nqi hloov tag nrho thoob plaws hauv lub voj voog kev pabcuam.
