Chaw ntim khoom
Raws li dauvethyl formamide (DMF) yog cov tshuaj organic nrog cov nplaim taws thiab cov khoom siv hluav taws xob, cov ntsiab lus hauv qab no yuav tsum tau sau tseg thaum lub sijhawm cia:
1. Chaw cia khoom: DMF yuav tsum muab cia rau hauv qhov chaw txias, qhuav thiab muaj kev tiv thaiv zoo, zam kev ua cua ncaj qha thiab kub. Qhov chaw cia yuav tsum nyob deb ntawm hluav taws, kub thiab oxidant, tawg-ntawv pov thawj chaw.
2. Ntim: DMFs yuav tsum muab khaws cia rau hauv airtight ntim ntawm ruaj khov zoo, xws li iav fwj zoo, hwj yas lossis hlau nruas. Kev ncaj ncees thiab nruj ntawm cov thawv yuav tsum tau kuaj xyuas tsis tu ncua.
3. Tiv thaiv tsis meej pem: DMF yuav tsum tsis txhob sib xyaw nrog cov muaj zog oxidant, muaj zog acid, muaj zog hauv paus thiab lwm yam tshuaj kom tsis txhob muaj kev phom sij. Nyob rau hauv tus txheej txheem ntawm cia, chaw thau khoom, tsis siv thiab siv, saib xyuas yuav tsum tau them los tiv thaiv kev sib tsoo, kev sib txhuam thiab kev sib txhuam, kom tsis txhob muaj tougically.
4. Tiv thaiv cov hluav taws xob zoo li qub: hauv DMF cia, chaw thau khoom, thauj khoom, thauj khoom thiab siv cov txheej txheem, yuav tsum tiv thaiv cov hluav taws xob zoo li qub. Yuav tsum tau ua kom tsim nyog yuav tsum tau ua, xws li grounding, txheej, cov cuab yeej siv tshuaj tiv thaiv, thiab lwm yam.
5. Daim Ntawv Cim Npe: DMF ntim yuav tsum khij nrog hnub kom meej thiab cim, kom muaj nuj nqis, kom muaj ntau ntxiv, kom muaj lwm yam, yog li los pab tswj hwm thiab cim.
