Tshuaj reagents yuav raug cuam tshuam los ntawm lwm yam xws li kub, lub teeb irradiation, huab cua thiab noo noo thaum lub sij hawm cia, tsheb thauj mus los thiab kev muag khoom, thiab yog nquag hloov mus rau lub cev thiab tshuaj xws li deliquescent, mycin, discoloration, polymerization, oxidation, volatilization, sublimation thiab decomposition. , ua rau lawv tsis muaj txiaj ntsig thiab siv tsis tau. Yog li ntawd, nws yog ib qho tsim nyog yuav tsum tau txais kev ntim khoom tsim nyog, tsim nyog cov xwm txheej thiab kev thauj mus los los xyuas kom meej tias cov tshuaj reagents tsis ua rau cov txheej txheem khaws cia, kev thauj mus los thiab kev muag khoom. Rau qee qhov kev xav tau tshwj xeeb rau kev khaws cia thiab kev thauj mus los, nws yuav tsum tau ua raws li cov cai tshwj xeeb. Qee cov tshuaj reagents muaj lub neej txee, yog li koj yuav tsum tau xyuam xim rau lawv thaum siv lawv.
Hnub tas sij hawm ntawm cov tshuaj reagent txawv heev nyob ntawm seb cov khoom siv tshuaj lom neeg ntawm cov tshuaj. Feem ntau, lub txee lub neej ntev ntawm cov tshuaj muaj zog ruaj khov, qhov yooj yim rau kev cia khoom.
