Izinhlobo mlilo

It is ukuthi mlilo uyindlela ebaluleke kakhulu futhi ephumelela kunazo ekulweni nomlilo ezaziwayo. Uma usebenzisa yona imizuzu embalwa ukumisa umlilo. Ngakho-ke, inhlangano ngayinye endaweni egqamile futhi kufinyeleleke kufanele zitholakale iyindlela eyinhloko ukuphepha umlilo. Nazi izinhlobo mlilo kuye izinto eziqukethwe kubo. Kungenzeka ngesimo amanzi, igwebu, impuphu, carbon dioxide, i-nitrogen nezinye amagesi inert amakhemikhali. Lapho ukwethulwa kwe-mlilo kusukela umlomo wombhobho yayo ekhiqizwa into is iqeda nomlilo. ekushayweni kokuqukethwe kwenzeka ngaphansi enomfutho.

Izinhlobo nezicimo esetshenziswa ngesikhathi imililo, ancike ubunjalo umlilo. Kunezinhlobo ezine ezivamile amakilasi umlilo, lesiniketwe amatshwayo okuhambisanayo. Ikilasi lokuqala (A) - evutha ndaba okuqinile, okuyinto kuhambisana yokubola. Lezi zihlanganisa ukhuni, iphepha, kanye nendwangu. Class B yakhiwa self ukushiswa izinto eziwuketshezi ezingenakho chaza emanzini (-benzene, petroleum ether), kanye izingxenye encibilikayo (utshwala, glycerol). Lokhu Class C libhekisela ukuthungela izinto gaseous (igesi yemvelo, propane). Fire ekilasini D - izinsimbi zivutha Alloys yalo (metal hydrides, compounds organometallic). Class E libhekisela umlilo kagesi.

Lapho ukuthungela okusamanzi, izinto eziqinile futhi gaseous asetshenziswa izinhlobo ezinjalo zokucima umlilo, powder. Powder jet iyiswe bacondze etindzaweni letehlukene ukuze futha amalangabi.

Lapho esekwenzile lokhu, kufanele ekugcineni ukumboza ungqimba ahlukene foci ukuthungela powder. Phakathi nale nqubo, kubalulekile ukuhambisa izingxenye eziphukile. Esikhathini omlilo of izinto okusamanzi (isigaba B umlilo), ukusakaza kufanele iqondiswe ngokuyinhloko ekupheleni proximal. Okuphakelayo powder kumele kwenziwe njalo. Kulokhu valve ivuliwe ngokugcwele. Kufanele ashukumiseleke ukuze emuva futhi izinhlangothi kwakungafanele izindawo ezivelele, futhi ezindaweni omlilo kufanele kugcinwe powder efwini.

Lapho ukuthungela izinto gaseous, isifutho powder kufanele iqondiswe ngqo ukusakaza igesi cishe kuhambisana jet gas. Lapho zokucisha ugesi (Yiqiniso, de-akukhuthalele) ukuqondisa indiza powder kufanele kube ilungelo umthombo ilangabi. Impilo ka- mlilo (ngokwesilinganiso) kuyinto iminyaka eyishumi.

Ukuze ucime imililo e Class B (ukuthungela uketshezi) kanye ikilasi E (kagesi) zohlobo olwalusetshenziselwa carbon dioxide mlilo. Liquefied carbon dioxide kuyinto umenzeli main asebenzayo. Ziyakwazi ngesandla, mobile futhi umile. Manual mlilo ucime ukufaka kagesi, kokuba voltage ka 1000V. ukusetshenziswa Ucingo ekucimeni uketshezi oluvuthayo wahlela indawo square metres ezinhlanu, njengoba usayizi encane kagesi, okuyizinto ngaphansi voltage. Zisetshenziswa kunjalo uma engathandeki, isibonelo, ukusetshenziswa kwamanzi (e zobuciko, iminyuziyamu kanye zomlando). Impilo isevisi ye-carbon dioxide mlilo - kuya kwezineminyaka eyishumi.

Cishe emhlabeni Foam esebenzayo mlilo. Basebenzisa Foam zamakhemikhali, eyatholakala kusukela izixazululo of alkalis futhi acid, kanye nomoya-mechanical, kwakhiwa okuyinto kusukela isixazululo aqueous of yesivini emoyeni ukusakaza kwe-carbon dioxide noma i-nitrogen.

Kukhona futhi izinhlobo ezinjalo zokucima umlilo, aerosol. Basuke esetshenziselwa ukucisha oluvuthayo uketshezi, oluvuthayo, kanye kagesi, ngaphansi kwamandla, izinto ezihlukahlukene ngaphandle insimbi alikhali futhi izinto elingenawo umoya-aqukethe. Basuke kungagcini ukuphila eshalofini iminyaka emihlanu.

Kukhona olunye uhlobo mlilo - a isicisha-mlilo powder, CAP-1 othomathikhi. It is lisetshenziswe imililo yesigaba A, B, C no E. Sici Its main - operation okuzenzakalelayo ngaphandle kokuqondiswa umuntu.

Ngamunye ngeke engadingekile ukuba ukhumbule ukuthi esikhathini uma kunengozi yomlilo ukuthola kuyadingeka uma kungenzeka, ngokushesha shayela iloli umlilo.
