Calcium carbide (CACN) yog aDej-Realive, Pherrophoric, ThiabKev ua kom huvCompound uas yuav tsum muaj cov kev cia ua kom tsis txhob muaj cov phom sij xws li cov roj acetylene roj tso tawm, hluav taws kub, lossis tawg.
1. Kev Cia
Qhuav ib puag ncig:
Khaws rau hauv aQhuav, zoo-villilated cheeb tsamNyob deb ntawm ya raws (piv txwv li, av noo, dej xau).
Kev sivAirtight, noo noo-ntawv pov thawj ntim(Piv txwv li, cov hlau nruas hlau lossis hnab yas-khi).
Tswj Qhov Kub:
Qhov zoo tshaj plaws kub:Hauv qab no 30 degreeKom txo qis thermal decomposition kev pheej hmoo.
Zam txhob kis lub hnub ci ncaj qha lossis cua sov.
2. Cov Thawv Yuav Tsum Tau
Khoom:
Kev sivCov Ntaub Ntawv Tsis Xav SivZoo li cov hlau, hlau stainless, 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 yogQhov cuam tshuam-resistantKom tiv thaiv kev puas tsuaj rau lub cev.
Ua kom ntseeg tau lub hau kaw ntom nti kom tsis txhob muaj huab cua thiab ya raws.
3. Cais cais los ntawm cov khoom txaus ntshai
Kom deb ntawm:
Cov Khoom Siv Dej(Piv txwv li, tog, dej, av noo).
Acids, Oxidizers (piv txwv li, chlorine, bromine), lossis reactive hlau (piv txwv li sodium, potassium).
Cov Khoom Siv Hluav Taws Xob(Piv txwv li, ntoo, ntawv) vim muaj kev pheej hmoo roj acetylene roj.
4. Kev muab qhib
Khaws rau hauv thaj chaw nrogYuam-cua qhov cuaTxhawm rau tiv thaiv acetylene roj zuj zuj.
Zam kev kaw chaw (piv txwv li, hauv qab, chav me me) uas tsis muaj Airflow uas tsis muaj Airflow.
5. Sau npe thiab kos npe
Daim ntawv qhia meej lub ntim nrog:
"Calcbide Carbide - Dej-Resultive"
Cov cim kev phom sij (piv txwv li cov roj av, xeb).
Tshaj tawm cov cim ceeb toom nyob ze:
"Tsis haus luam yeeb"
"Cia kom qhuav"
6. Cov Khoom Muag Khoom
Thawj-hauv-thawj-tawm (Fifo): Siv cov khoom qub ua ntej los txo cov phom sij cia kev phom sij ntev.
Txo kom muaj nuj nqis: Khaws cia cov nqi uas tsim nyog; Zam kev cia tshwj tsis yog tus lej kev nyab xeeb.
7. Kev npaj tos xwm ceev
Hluav taws kub tua hluav taws: Khaws Chav Kawm D (Hlau Hluav Taws Xob) thiab cov tua hluav taws nyob ze.
Cov khoom siv spill: Suav cov khoom lag luam (piv txwv li, cov xuab zeb, calcium carbonate) thiab ppe (hnab looj tes (hnab looj tes).
Dej xau:
Yog tias nchuav, cais tawm thaj tsam thiab cheb cov khoom rau hauv cov thawv qhuav.
Neutralize spills nrog cov kua qaub uas tsis muaj zog (xws li, vinegar) kom hloov acetylene roj.
8. Kev Tswj Fwm
Raws qabOsha(Asmeskas) thiabNFPA 495(Qauv rau kev sib txuas ua ke hlau) cov txheej txheem.
Ua raws liUN HITR puas chav kawm 4.3(Dej-realive cov khib nyiab) rau kev thauj mus los thiab cia.
9. Cov kev txiav txim siab tshwj xeeb
TEST cia:
Khaws rau hauv desiccator lossis hauv qab roj (piv txwv li, nitrogen) yog khaws cia ntev ntev.
Muaj Cia Khoom:
Siv cov chaw cia khoom nrog txig muaj cov tshuab hluav taws xob.
