Muaj kev ruaj ntseg txee
1 yuav tsum xyuam xim kom zoo qhov cua
Qhov ntau dua qhov vapor ntom ntawm cov yeeb yam, qhov yooj yim dua qhov vapor nyob qis qis hauv ib qho chaw. Yog li ntawd, nws yuav tsum tau ceev cia zoo ventilated.
Ib qho kev raug mob me me uas tshwm sim:
Thaum lub hwj uas tau ntxuav nrog acetone thiab tom qab ntawd qhuav hauv ib lub thawv qhuav, cov acetone residual vaporized ua rau muaj kev tawg, ua rau lub qhov cub tawg ntawm lub qhov cub kom qhuav thiab ya mus deb.
2 kua nrog lub teeb nyem siab yog ib qho nyuaj rau tua
Ib yam khoom uas muaj lub siab nyem, ib zaug ntes tau rau hauv hluav taws, feem ntau tsis yooj yim rau tua vim tias qhov kub siab ntawm kev daws teeb meem.
3 them nqi kom hnav cov khoom tsim nyog tiv thaiv
Thaum cov cua kub hnyiab los sis tuav ntau yam khoom kub hnyiab, tus kws ntsuas yuav tsum hnav daim npog tiv thaiv thiab hnab looj tes.
Ib qho kev raug mob me me uas tshwm sim:
Cov kua rhaub tau muab tso rau hauv ib qho kev nrug funnel thiab muab rho tawm nrog xylene. Thaum cov hiav txwv ntawm cov nkauj nraug qhib tau qhib, cov xylene uas raug rho tawm tam sim ntawd ua rau hluav taws.
4 xyuam xim seb qhov hluav taws kub extinguishing txujci puas yog
Cov khoom kub nyhiab yog kub nyhiab, feem ntau muaj ib qho me me sib ntau, thiab siv cov roj carbon dioxide tua hluav taws kom tua cov hluav taws. Thaum qhov hluav taws kub loj, cov khoom siv yuav tua tau cov dej. Yog li ntawd, them nqi rau qhov tsim nyog tua hluav taws extinguishing method.
Ib qho kev raug mob me me uas tshwm sim:
Cov roj da dej tau ntes tau hluav taws thiab tua tau los ntawm carbon tetrachloride. Yog li ntawd, cov kua carbon tetrachloride yuav ua rau hauv cov roj, ua rau cov roj txaws ntawm qhov hluav taws kub, uas tshwm sim los ntawm qhov hluav taws kub kom nthuav.
Thaum muaj hlau ntau ntau ua rau hluav taws kub, nws yog qhov zoo tshaj plaws los siv cov xuab zeb los yog cov hmoov tua hluav taws qhuav. Piv txwv, thaum txhuas hmoov yog nyob rau hauv hluav taws, yog nws tua tau dej, qhov hluav taws kub yuav hlawv ntau dua.
5 xyuam xim rau cov khoom ntub uas kub hnyiab
Ceev faj:
1 Tso rau hauv ib qho chaw txias, cua, qhov chaw qhuav ntawm qhov hluav taws kub, cua sov, oxidants thiab acids.
2 Qhov kub ntawm cov kua flammable yuav tsum tsis pub dhau 30 ° C, xws li: roj av, ethanethiol, diethylamine, ether, acetone, thiab lwm yam.
3 cov hluav taws kub hnyav yuav tsum tau raug tiv thaiv los ntawm ya raws thiab mildew. Piv txwv: N, N-dinitropentamethylenetetramine [(CH2) 5 (NO) 2N4], dinitronaphthalene, liab phosphorus, thiab cov zoo li. Cov phev hmoov hmoov absorbs noo noo thiab heats li, ua rau kub.
4 Tsis txhob sib tov nrog lwm cov tshuaj phom lub siab. Khaws lawv nyias.
5 Maj mam maj, nws txwv tsis pub yob, rub thiab tsoo.
6 kev kuaj xyuas tsis tu ncua.
