Imbali Yezixhobo Zokucima Umlilo
Izixhobo Zokulwa Nomlilo Kwasekuqaleni
Ngaphambi kokuyilwa kweinto yokucima umlilo, iimpucuko zamandulo zazixhomekeke kwizixhobo ezisisiseko zokulwa nemililo. Iibhakethi zamanzi, iingubo ezimanzi, kunye nesanti yayizezona ndlela ziphambili ezazisetyenziswa ukucima amadangatye. KwiRoma yamandulo, amaqela acwangcisiweyo okulwa nomlilo, awayebizwa ngokuba yi-“Vigiles,” ayesebenzisa iimpompo zesandla kunye neebhakethi zamanzi ukulawula imililo kwiindawo zasezidolophini. Ezi zixhobo, nangona zisebenza ngandlela ithile, zazingenalo ulungelelwano kunye nokusebenza kakuhle okufunekayo ukusombulula imililo ngokukhawuleza.
Uguquko lwezeMizi-mveliso luzise inkqubela phambili kubuchwepheshe bokucima umlilo. Kwavela izixhobo ezifana neempompo zomlilo ezisebenza ngesandla kunye neesirinji, nto leyo eyavumela abacimi-mlilo ukuba baqondise imijelo yamanzi ngokuchanekileyo. Nangona kunjalo, ezi zixhobo zazizininzi kwaye zazifuna abantu abaninzi ukuba bazisebenzise, nto leyo eyayinciphisa ukusebenza kwazo xa zisetyenziswa ngumntu ngamnye okanye kancinci.
Isicima-mlilo sokuqala ngu-Ambrose Godfrey
Ngo-1723, u-Ambrose Godfrey, ingcali yemichiza yaseJamani, waguqula ukhuseleko lomlilo ngokunika ilungelo elilodwa lomenzi womlilo wokuqala. Uyilo lwakhe lwaluquka ibhokisi egcwele ulwelo olucima umlilo kunye negumbi elinempuphu yezibhamu. Xa isebenza, umpu wezibhamu waqhuma, wasasaza ulwelo phezu kwamalangatye. Olu yilo lutsha lwabonelela ngendlela ejolise ngakumbi nesebenzayo yokucima umlilo xa kuthelekiswa neendlela zangaphambili.
Iingxelo zembali zibonisa ukusebenza kakuhle kwento eyaveliswa nguGodfrey ngexesha lomlilo eCrown Tavern eLondon ngo-1729. Esi sixhobo sawulawula ngempumelelo umlilo, sibonisa amandla aso njengesixhobo sokusindisa ubomi. Isitshizi somlilo sikaGodfrey saphawula ukuqala kwexesha elitsha kukhuseleko lomlilo, sikhuthaza ubuchule bexesha elizayo kubuchwepheshe bokucima umlilo.
Utshintsho kwiZicimi-mlilo zanamhlanje eziphathwayo
Uhambo oluvela kwimveliso kaGodfrey ukuya kwisicima-mlilo sanamhlanje lubandakanye amanyathelo amaninzi. Ngo-1818, uGeorge William Manby wazisa isitya sobhedu esiphathwayo esinesisombululo se-potassium carbonate phantsi komoya ocinezelweyo. Olu yilo lwavumela abasebenzisi ukuba batshize isisombululo ngqo elangatyeni, nto leyo eyenza ukuba sisebenziseke ngakumbi kumntu ngamnye.
Utshintsho olulandelayo lwaphucula ngakumbi izicimi-mlilo. Ngo-1881, u-Almon M. Granger wanelungelo lobunikazi lesi sicimi-mlilo se-soda-acid, esasebenzisa impendulo yekhemikhali phakathi kwe-sodium bicarbonate kunye ne-sulfuric acid ukwenza amanzi axinzelelweyo. Ngo-1905, u-Alexander Laurant wavelisa isicimi-mlilo se-foam sekhemikhali, esabonakala sisebenza ngokuchasene nemililo yeoyile. Inkampani iPyrene Manufacturing Company yazisa izicimi-mlilo ze-carbon tetrachloride ngo-1910, inikezela ngesisombululo semililo yombane.
Kwinkulungwane yama-20 kwavela izixhobo zokucima umlilo zanamhlanje ezisebenzisa i-CO2 kunye neekhemikhali ezomileyo. Ezi zixhobo zaba ncinci, zisebenza kakuhle, kwaye zisebenziseka lula, zilungele iindidi ezahlukeneyo zomlilo. Namhlanje,izicima-mlilozizixhobo eziyimfuneko emakhayeni, kwiiofisi nakwiindawo zoshishino, ukuqinisekisa ukhuseleko kunye nokunciphisa iingozi ezinxulumene nomlilo.

Utshintsho lwezicimi-mlilo lubonisa ukuzinikela koluntu ekuphuculeni ukhuseleko lomlilo. Utshintsho ngalunye luye lwanegalelo ekwenzeni izicimi-mlilo zifikeleleke lula, zisebenze kakuhle kwaye zithembeke.
Uphuhliso lweTekhnoloji kwiZicimi-mlilo
Uphuhliso lwee-Ctinguishing Agents
Uphuhliso lwezinto ezicima umlilo luye lwaphucula kakhulu ukusebenza kakuhle kwezicimi-mlilo. Uyilo lwangaphambili lwaluxhomekeke kwizisombululo ezisisiseko ezifana ne-potassium carbonate okanye amanzi, ezazinqongophele kubuchule bazo bokulwa neentlobo ezahlukeneyo zomlilo. Uphuhliso lwanamhlanje lwazisa izinto ezikhethekileyo ezenzelwe iindidi ezithile zomlilo, nto leyo ephucula ukhuseleko kunye nokusebenza kakuhle.
Njengokuba,iikhemikhali ezomileyo, njenge-monoammonium phosphate, yasetyenziswa kakhulu ngenxa yokuguquguquka kwayo ekucimeni imililo yeClass A, B, kunye neC. Ezi arhente ziphazamisa iimpembelelo zeekhemikhali ezivuselela umlilo, nto leyo eyenza ukuba zisebenze kakhulu. I-Carbon dioxide (CO2) yavela njengolunye uphuhliso olubalulekileyo. Amandla ayo okususa ioksijini kunye namalangatye abandayo ayenze yafaneleka kwimililo yombane kunye nolwelo oluvuthayo. Ukongeza, iiarhente zeekhemikhali ezimanzi zaphuhliswa ukuze zijongane nemililo yeClass K, efumaneka rhoqo kwiikhitshi zorhwebo. Ezi arhente zenza umaleko wesepha phezu kweeoyile ezivuthayo kunye namafutha, zithintela ukuphinda zivuthe.
Izicimi-mlilo ezicocekileyo, ezisebenzisa iigesi ezifana ne-FM200 kunye ne-Halotron, zimele inyathelo eliya phambili kukhuseleko lomlilo. Ezi zixhobo aziqhubi kwaye azishiyi ntsalela, nto leyo ezenza zifaneleke kwiindawo ezinezixhobo ezinobuthathaka, ezifana namaziko edatha kunye neemyuziyam. Ukuphuculwa okuqhubekayo kwee-agents zokucima umlilo kuqinisekisa ukuba izicimi-mlilo zihlala zisebenza kwiimeko ezahlukeneyo.
Uyilo lweZicimi-mlilo ezintsha
Uphuhliso kuyilo luye lwaguqula izicimi-mlilo zaba zizixhobo ezisebenziseka lula nezisebenzayo. Iimodeli zakuqala zazinkulu kwaye zinzima ukuzisebenzisa, zithintela ukufikeleleka kwazo. Uyilo lwanamhlanje lubeka phambili ukuphatheka lula, ukusetyenziswa lula, kunye nokuqina, ukuqinisekisa ukuba abantu banokusabela ngokukhawuleza ngexesha likaxakeka.
Enye into entsha ephawulekayo kukungeniswa kweegeyiji zoxinzelelo, ezivumela abasebenzisi ukuba baqinisekise ukuba isitshizi somlilo sikulungele na ngokujonga nje. Olu phawu lunciphisa umngcipheko wokusebenzisa isixhobo esingasebenziyo ngexesha elibalulekileyo. Ukongeza, iziphatho ze-ergonomic kunye nezixhobo ezikhaphukhaphu ziye zaphucula ukusetyenziswa kwezitshizi zomlilo, nto leyo evumela abantu abanezakhono ezahlukeneyo zomzimba ukuba bazisebenzise ngokufanelekileyo.
Olunye uphuhliso olubalulekileyo kukufakwa kweelebheli ezinemibala kunye nemiyalelo ecacileyo. Olu phuculo lwenza kube lula ukuchongwa kweentlobo zezicimi-mlilo kunye nokusetyenziswa kwazo okufanelekileyo, kunciphisa ukudideka ngexesha leemeko zoxinzelelo olukhulu. Ngaphezu koko, ukuqhubela phambili kwitekhnoloji ye-nozzle kuphucule ukuchaneka kunye nokufikelela kwezinto ezicima umlilo, kuqinisekisa ukuba imililo inokujongwa ngempumelelo.
