Calcium carbide (cac₂) - yogDej-Realive,pherrophoricThiabkev ua kom huvIb qho sib xyaw uas yuav tsum muaj cov kev cia ua kom tsis txhob muaj kev phom sij xws li tso cov tshuaj acetylene roj, hluav taws kub, lossis tawg.
1. Kev Cia
Qhuav ib puag ncig:
Khaws rau hauvQhuav, zoo-ventilated qhov chaw, kom deb ntawm ya raws (piv txwv li av noo, dej xau).
Kev sivairtight, noo noo-ntawv pov thawj ntim(xws li cov hlau sib khi lossis cov hnab yas yas yas).
Tswj Qhov Kub:
Qhov zoo tshaj plaws kub:Hauv qab no 30 degreekom txo qis kev pheej hmoo ntawm kev ua kom thermal.
Zam txhob kis lub hnub ci ncaj qha lossis cua sov.
2. Yuav tsum muaj rau cov thawv
Khoom:
Kev sivCov Ntaub Ntawv Tsis Xav Siv, xws li hlau, stainless hlau lossis polyethylene lined ntim.
Zam kev txhuas lossis cov thawv tooj liab (pheej hmoo ntawm exothermic kev tawm tsam).
Kev tsim ua:
Cov thawv yuav tsum yogkev poob siabkom tiv thaiv kev puas tsuaj rau lub cev.
Xyuas kom meej tias lub hau haum nruj kom tiv thaiv huab cua thiab noo noo ntawm nkag mus.
3. Sib cais los ntawm cov khoom txaus ntshai
Kom deb ntawm:
Cov Khoom Siv Dej(E.G. Sinks, dej, noo noo).
Acids, oxidizing cov neeg sawv cev (piv txwv li chlorine, bromine) lossis reactive hlau (piv txwv li sodium, potassium).
Cov Khoom Siv Hluav Taws Xob(E.g. Ntoo, Ntawv) Vim -}}} Vim muaj kev phom sij ntawm kev siv acetylene roj.
4. Kev muab qhib
Khaws rau hauv cov chaw nrogyuam kom dim paTxhawm rau tiv thaiv cov kev sib txuam ntawm cov tshuaj acetylene roj.
Zam kev kaw chaw (piv txwv li hauv qab daus, cov chav me) tsis muaj huab cua kom txaus sib pauv.
5. Cim thiab Cov paib
Daim ntawv sau kom meej meej taw qhia:
"Calcbide Carbide - dej-reactive"
Cov cim kev phom sij (piv txwv li cov roj av, corrosion).
Tshaj tawm cov cim ceeb toom nyob ze:
"Tsis haus luam yeeb"
"Khaws rau hauv qhov chaw qhuav."
6. Cov Khoom Muag Khoom
Ua ntej hauv - ua ntej tawm (Fifo): Siv cov khoom qub ua ntej kom txo qis kev pheej hmoo ntawm kev pheej hmoo ntawm lub sijhawm ntev cia.
Kom muaj nuj nqis: Khw tsuas yog tsim nyog cov khoom; Zam kev cia tshwj tsis yog tias kev tswj hwm kev nyab xeeb.
7. Kev npaj tos xwm ceev
Hluav taws kub tua hluav taws: Khaws Chav Kawm D (Rau Cov Hluav Taws Kub) thiab cov tua hluav taws uas nyob ze.
Spill teb cov khoom haus: Suav nrog cov khoom siv (xws li xuab zeb, cov carnium carbonate) thiab ppe (hnab looj tes, tsom iav kev nyab xeeb).
Kho lub xau dej:
Thaum muaj tej roj av, cais thaj tsam thiab sau cov khoom siv hauv cov thawv qhuav.
Neutralize lub txeej no nrog cov kua qaub tsis muaj zog (xws li vinegar) kom hloov acetylene roj.
8. Kev Tswj Fwm
Ua raws li cov tseev kom muajOsha(Tebchaws Asmeskas) thiabNFPA 495(Cov hlau sib txuam ntawm cov qauv hlau).
Thaum lub sijhawm thauj mus los thiab cia, saibUN HITR puas chav kawm 4.3(cov khib nyiab uas hnov mob nrog dej).
9. Cov kev txiav txim siab tshwj xeeb
TEST cia:
Rau lub sijhawm ntev cia, khaws cia rau hauv cov tshuaj tua kab mob lossis hauv cov roj hauv cov roj (piv txwv li, nitrogen).
Muaj Cia Khoom:
Siv cov chaw cia khoom nrog txig muaj cov tshuab hluav taws xob.
