Txawm hais tias xim - hloov silica gel tuaj yeem raug ntxuav thiab rov qab siv dua tom qab kis kab mob yog nyob ntawm qhov kev sib kis. Cov kab mob me me tuaj yeem raug ntxuav thiab rov qab los, thaum cov kab mob loj heev tsis tuaj yeem kho thiab tsis pom zoo rau rov siv dua.
1. Kev paug me me: Kev ntxuav thiab rov siv dua tuaj yeem sim
Muaj feem xyuam rau cov xwm txheej uas tsuas yog qhov chaw uas muaj plua plav, me ntsis roj stains, los yog tau nkag mus rau hauv ib puag ncig:
(1) Txoj Kev Ntxuav Dej (pom zoo)
Cov kauj ruam:
Ncuav cov silica gel hais rau hauv lub lim lossis gauze;
Yaug ntau zaus nrog dej ntws kom tshem tawm cov av;
Muab tso rau hauv lub tshav kub-cov thawv uas tiv taus tom qab ntxuav;
Qhuav nyob rau hauv ib tug 100-120℃qhov cub rau 1-2 teev kom tag lub cev qhuav dej thiab regenerate;
Sau thiab khaws cia tom qab txias.
Cov Cai Txiav Txim: Cov xim rov qab ua tiav tom qab cua sov (xiav → xiav, txiv kab ntxwv → txiv kab ntxwv), tsis muaj ntxhiab tsw.
(2) Txoj Kev Kho Dej Cawv (Kev Kho Mob Thaum Muaj Xwm Ceev)
Kev Ua Haujlwm: Muab cov paj rwb pov rau hauv ib qho me me ntawm 75% kev kho mob cawv thiab maj mam so qhov chaw ntawm cov khoom tsis huv;
Ceev faj: Tsis txhob ntub dej ntau kom tsis txhob haus cawv los ntawm kev nkag mus rau micropores thiab ua rau muaj kev puas tsuaj me me;
Kev kho tom qab: Cua qhuav + siab -kub kom qhuav kom lub cev qhuav dej tiav.
Txoj kev no tuaj yeem tshem tawm qee cov organic residues, tab sis tsis tuaj yeem tshem tawm cov kab mob uas tau nkag mus tob rau hauv qhov pores.
2. Cov kab mob hnyav heev: Kev ntxuav tsis zoo thiab cov khoom siv tsis tuaj yeem rov qab siv dua.
Yog tias cov xwm txheej hauv qab no tshwm sim, nws qhia tau tias micropores raug thaiv mus tas li thiab kev ntxuav tsis tuaj yeem rov ua haujlwm:
Contamination Manifestations Conclusion
Cov khoom yog xim dub, daj, los yog cov cim qhia ntawm charring. Micropores raug thaiv hnyav, thiab lub peev xwm adsorption poob.
Emitting pungent fumes los yog tsw thaum rhuab. Muaj cov tshuaj tsis haum xeeb, ua rau muaj kev phom sij.
Greasy, clumpy, los yog softened rau qhov kov. Kev puas tsuaj, irreversible.
Siv rau kev tiv thaiv noo noo ntawm zaub mov, tshuaj, thiab khoom siv hluav taws xob. Kev hloov pauv tau pom zoo txawm tias muaj kab mob me me.
Kev Ceeb Toom Tshwj Xeeb: Kev ntxuav tsis tuaj yeem rov qab nws lub peev xwm adsorption sab hauv thiab tuaj yeem ua rau hla -kev pheej hmoo kis kab mob. Nws yog txwv tsis pub siv rau hauv cov xwm txheej tiv thaiv qhov tseeb. 3. Cov Lus Qhia Txog Kev Nyab Xeeb thiab Ib puag ncig
Cobalt Chloride (Blue) Silica Gel: Qhov no yog ib qho tshuaj lom neeg seem thiab yuav tsum tsis txhob muab pov tseg.
Nws yuav tsum tau muab ntim rau hauv ntim thiab sau tias "Cobalt-Khoom pov tseg." Muab pov tseg ntawm qhov chaw pov tseg pov tseg lossis xa mus rau lub chaw ua haujlwm pov tseg.
Cobalt- Dawb Ib puag ncig phooj ywg (txiv kab ntxwv) Silica Gel: Nws tuaj yeem raug kaw thiab muab pov tseg raws li cov pov tseg zoo tib yam los tiv thaiv cov plua plav tawg.
