Cov Ntsiab Cai ntawm Kev Txiav Txim Siab Ntawm Cov Tshuaj Reagents
Nov 03, 2021
Txhawm rau txiav txim siab qhov ruaj khov ntawm cov khoom ua ntej, cov hauv qab no tuaj yeem ua raws:
Inorganic compounds tuaj yeem siv tau ntev npaum li lawv tau khaws cia kom zoo thiab ntim khoom tsis zoo. Txawm li cas los xij, cov khoom uas yooj yim oxidized thiab deliquescent tsuas yog khaws cia rau lub sijhawm luv luv (1 txog 5 xyoos) nyob rau hauv qhov tsaus ntuj, txias, thiab qhuav, nyob ntawm seb qhov ntim thiab ntim khoom puas ua raws li cov cai.
Organic low-molecular-weight compounds yog feem ntau volatile, thiab lub ntim tau zoo airtightness thiab yuav khaws cia rau lub sij hawm ntev. Tab sis nws yog ib qho yooj yim rau oxidized, decomposed los ntawm tshav kub, yooj yim rau polymerize, photosensitive tshuaj, thiab lwm yam.
Organic polymers, tshwj xeeb tshaj yog cov khoom siv hauv lub neej xws li roj, polysaccharides, proteins, enzymes, peptides, thiab lwm yam, yog qhov cuam tshuam rau cov kab mob, qhov kub thiab txias, thiab lub teeb, thiab poob lawv cov kev ua haujlwm lossis tsis zoo. Yog li ntawd, lawv yuav tsum tau muab cia rau hauv qhov txias txias (khov), thiab lub sijhawm ntev dhau lawm. luv dua.
Hauv cov ntsiab lus, cov ntaub ntawv siv, cov ntaub ntawv txheem thiab cov khoom siv purity siab yuav tsum tau muab khaws cia kom nruj raws li cov cai tswj xyuas kom ntseeg tau tias cov ntim khoom tsis zoo, tsis txhob cuam tshuam los ntawm cov tshuaj ib puag ncig, thiab lub sijhawm khaws cia yuav tsum tsis txhob ntev dhau. Feem ntau, cov ntaub ntawv siv yuav tsum tau siv nyob rau hauv lub sijhawm siv tau.
Kev ruaj ntseg ntawm cov tshuaj feem ntau tseem yog qhov zoo, thiab cov xwm txheej tshwj xeeb yuav tsum tau txiav txim siab los ntawm kev siv tiag tiag. Yog tias cov ntaub ntawv txheeb xyuas tau siv los ua kev nkag siab dav dav, lossis tsis muaj qhov tshwj xeeb thiab raug cai rau kev soj ntsuam cov txiaj ntsig, xws li kev sim qhia dav dav, cov qib zoo ntawm cov tshuaj reagents feem ntau yuav tsum tau ua. Txawm li cas los xij, cov ntaub ntawv kuaj xyuas lub Hoobkas yog siv los qhia kev tsim khoom, thiab cov ntsuas zoo ntawm cov tshuaj reagents yuav tsum tsis meej. Raws li rau cov tshuaj reagents siv nyob rau hauv kev npaj hluavtaws hluavtaws, feem ntau, kev siv cov tshuaj reagents qib industrial yog txaus. Txawm li cas los xij, kev npaj hluavtaws ntawm kev tshawb fawb-hom thiab qee yam tshuaj tshwj xeeb, qee zaum, muaj cov kev cai nruj heev ntawm cov khoom siv raw zoo thiab yuav tsum muaj kev tswj xyuas nruj.
Hauv kev siv tiag tiag, tib neeg yeej ib txwm siv los txiav txim qhov ua tau zoo ntawm cov tshuaj reagents los ntawm hnub tsim khoom. Qhov tseeb, nws yog absurd. Piv txwv li, nyob rau hauv ib lub tsev kawm ntawv qib siab ntawm kev kawm ntawv qib siab, ib zaug kuv pom cov thawj coj hauv tsev khaws khoom ntxuav tawm tag nrho cov tshuaj reagents uas tau tawm ntawm lub Hoobkas ntau tshaj 2 xyoos, thiab npaj ua kom puas, vim yog vim li cas lawv tau tas sij hawm. Tsis hais txog cov nyiaj pov tseg loj, txoj kev npaj ua kom puas tsuaj ntawm ntau yam khoom siv tshuaj lom neeg ib leeg yog txaus los txwv. Dab tsi' ntau dua, cov tuam txhab lag luam tsis tso cai yuav, tiv thaiv kev lag luam los ntawm" dag neeg", qhov xwm txheej tsis txaus ntseeg, thiab qhov xwm txheej nyuaj siab! Tom qab ntawd, nws tau hais tias qhov ntau ntawm cov tshuaj reagents yog" tob tob tob thiab faus".
Hauv ntej, qhov ua tau zoo ntawm cov tshuaj reagents yuav tsum xub txiav txim siab raws li lub cev thiab cov khoom siv tshuaj lom neeg ntawm cov tshuaj reagents lawv tus kheej, thiab tom qab ntawd cov xwm txheej khaws cia ntawm cov tshuaj reagents yuav tsum tau saib pom, thiab tom qab ntawd qhov xaus ntawm seb lawv puas tuaj yeem siv tau. ua raws li cov kev xav tau tshwj xeeb.
