Methylene chloride, ikaba ari organic organic.

Ibyiza:Byeramethylene chlorideNta flash point.Umuti urimo ibipimo bingana bya dichloromethane na lisansi, naphtha ya solvent cyangwa toluene ntabwo byaka.Ariko, iyo dichloromethane ivanze na acetone cyangwa methyl Amazi ya alcool ya chimique ya 10: 1 ivanze, ivangwa rifite flash point, imyuka numwuka kugirango bibe ivangavanga riturika, imipaka iturika 6.2% ~ 15.0% (ingano).

GUSABA:

1. Byakoreshejwe muguhunika ingano no gukonjesha firigo yumuvuduko muke hamwe nicyuma gikonjesha.

2, Ikoreshwa nka solvent, ikuramo, agent ya mutagenic.

3, Ikoreshwa mu nganda za elegitoroniki.Mubisanzwe bikoreshwa nkibikoresho byoza amavuta.

4, Ikoreshwa nk'amenyo ya anesthetic yaho, firigo, icyuma kizimya umuriro, icyuma cyo hejuru cyicyuma gisukura kandi cyangiza.

5, Byakoreshejwe nkigihe gito muri synthesis organique.

Uburyo bwo kwitegura:

1. Gahunda ya gaz ya chlorine naturel Gazi isanzwe ikora na gaze ya chlorine.Nyuma ya aside ya hydrochlorike ikorwa na hydrogène chloride yinjizwa n’amazi, ibisigisigi bya hydrogène chloride isigara ikurwaho na lye, kandi ibicuruzwa byarangiye bikaboneka binyuze mu kumisha, kwikanyiza, kwegeranya no kubitandukanya.

2. Chloromethane na chloromethane byakoresheje gaze ya chlorine munsi yumucyo wa 4000kW kugirango itange dichloromethane, yarangijwe no gukaraba alkali, kwikanyiza, kwegeranya, gukama no gukosora.Ibyingenzi byingenzi ni trichloromethane.

Umutekano:

1.Icyitonderwa cyo gukora:Irinde ibitonyanga by'igihu mugihe cyo gukora, kandi wambare ibikoresho bikingira umuntu.Irinde kurekura ibitonyanga hamwe nibicu mumyuka yumurimo.Korera ahantu runaka ufite umwuka mwiza kandi ufate umubare muto.Ibikoresho byo gutabara byihutirwa bigomba kuboneka igihe cyose kugirango birwanye umuriro no guhangana n’isuka.Ibikoresho byabitswe birimo ubusa birashobora kuba birimo ibisigazwa bishobora guteza akaga.Ntugakorere hafi yo gusudira, gucana, cyangwa ahantu hashyushye.

2.Uburyo bwo kubika:Ubike ahantu hakonje, humye, gahumeka neza nta zuba ryizuba.Ubike kure yubushyuhe, flame nibidashoboka nka okiside ikomeye, aside ikomeye na aside nitric.Ubike mubikoresho byanditse neza.Ibikoresho bidakoreshejwe n'ingoma zirimo ubusa bigomba gutwikirwa cyane.Irinde kwangirika kuri kontineri kandi ugenzure ikigega buri gihe kubera inenge nko kumeneka cyangwa kumeneka.Ibikoresho birimo umurongo wa galvanis cyangwa fenolike kugirango bigabanye amahirwe yo kubora methylene chloride.Ububiko buke.Kohereza ibimenyetso byo kuburira aho bikenewe.Ahantu ho guhunika hagomba gutandukanywa nabakozi bakora cyane kandi bakagabanywa kugera mukarere.Koresha imiyoboro ya pulasitike yagenewe gukoreshwa hamwe no gusohora ibintu bifite uburozi.Ibikoresho bishobora kubaka amashanyarazi ahamye ashobora gutera umuriro.Bika ahantu hakonje, humye, hahumeka neza kure yizuba ryinshi.

3.Gupakira no gutwara:Koresha ingunguru yicyuma kugirango ufunge, 250 kg kuri barrale, tanker ya gari ya moshi, imodoka irashobora gutwarwa.Igomba kubikwa ahantu hakonje, hijimye, humye, hahumeka neza, witondere ubushuhe.
