Amalangabi umlilo okuphansi ezahlukene

lokushisa Fire kubangela ukukhanya entsha ukubona izinto evamile - kubaneka umdlalo ezimhlophe, kukhanya blue sikaphalafini igesi isitofu ekhishini, ngezilimi orange-bomvu ka amalangabi izinkuni. Lo baba akanalo sinake umlilo baze ashise amathiphu yeminwe yakhe. Noma zange alale amazambane epanini. Noma prozhzhot amathe amateki, iphele phezu komlilo.

Lapho izinhlungu zithi lokuqala, ukwesaba nokukhungatheka, sekuyisikhathi kuveza zefilosofi. Imvelo, imibala, izinga lokushisa, umlilo.

It wokhela sengathi umdlalo

Kafushane mayelana nesakhiwo umdlalo. Siqukethe sezinsaba ikhanda. Izinduku zenziwa ngokhuni, amakhadibhodi ukotini uzi lwefilakisi elingabhuliwe, ukuba afuthwe ngesibulali upharafini. Izinkuni akhethiwe softwood - Poplar, uphayini, e-aspen. izinto zokusetshenziswa for induku ibizwa ngokuthi izinti umdlalo. Ukuze ugweme inkohlakalo simunyangaso, izinti afuthwe ngesibulali wali band acid. izimboni Russian izinti ezibaziweyo kusukela e-aspen.

Shona Match ilula ngefomu kodwa eyinkimbinkimbi ukubunjwa yabo zamakhemikhali. Obunsundu umdlalo ikhanda iqukethe izingxenye eziyisikhombisa: oxidizing - bertoletova usawoti kanye potassium dichromate; steklyannyuu uthuli minium lomthofu, nesibabule, ithambo glue, zinc emhlophe.

Shona Match ibangelwa friction, sishisiswe ayinkulungwane degrees. Ignition embundwini degrees Celsius :

• Poplar - 468;
• Aspen - 612;
• Pine - 624.

umlilo okuphansi umdlalo ilingane lokushisa ukuthungela kwezinkuni. Ngakho-ke, flash ikhanda mhlophe esikhundleni nge sulfuric ophuzi ulimi okufanayo.

Uma sihlolisisa umdlalo esivuthayo ke bheka avele ezintathu zone ilangabi. Lower - blue abandayo. Isilinganiso isigamu ukufudumala kakhulu. Engaphandle - zone hot.

Fire umculi

Ngesikhathi igama elithi "umlilo" flash engengaphansi ngokukhazimulayo nostalgic izinkumbulo: intuthu umlilo, ukudala indawo ukuthembela kokungekhona; izibani red yellow Undizela ultramarine esibhakabhakeni; ukudlala ngezilimi blue Ruby-obomvu umbala; Amalahle njengegazi ukupholisa phansi elinakekela "Pioneer" amazambane.

Umbala ekushintsheni wenqola izinkuni umlilo ibika ekushintshashintsheni ku lokushisa komlilo. ukhuni kwamazinyo (ukuhwalala) iqala 150 °. Ignition (ufasimbe) kwenzeka esikhathini sokuphumula 250-300 °. Ukuze zemithi efanayo engena umoya-mpilo ashise okushisa ahlukile. Ngakho, izinga umlilo beyoba ezahlukene. Birch burning at degrees 800, Alder - at 522 °, futhi umlotha, beech - at 1040 °.

Kodwa umbala umlilo nalo kunqunywa ukubunjwa amakhemikhali izidakamizwa esivuthayo. Ophuzi kanye orange amalangabi okwenza sodium usawoti. Chemical Ukwakheka yakhiwa cellulose kanye sodium usawoti kanye potassium usawoti, enikeza elikhazimulayo amalahle isihlahla luhlaza obomvu. Romance kwamalambu aluhlaza emlilweni ukhuni zenzeka ngenxa yokushodelwa umoya, esikhundleni sokuthi uma CO ₂ kwakhiwa CO - carbon monoxide.

Abathandi ucwaningo lwesayensi ukukala izinga lokushisa komlilo lisebenze umlilo ngokuthi i pyrometer. Manufactures ezintathu izinhlobo pyrometers: optical ngemisebe, Spectral. Lokhu amadivayisi yokuxhumana, okuvumela ukuhlola umthamo we emisebeni ezishisayo.

Ukufunda kusukela umlilo ekhishini lakho siqu

Ikhishi igesi izitofu ukusebenzisa ku zokubasa ezimbili:

1. Bulk igesi yemvelo-methane.
2. Le-butane ingxube kuncibilike igesi amathangi kanye amasilinda.

Ukwakheka kwamakhemikhali izinga lokushisa fuel igesi inquma ipuleti umlilo. Methane, evutha, umlilo yakha nomthamo degrees 900 phezulu.

Amandla omlilo ingxube kuncibilike liletha ukutjhisa kuya ku-1950 °.

A ingqapheli ngokucophelela uzophawula engalingani Umbala ngezilimi igesi sikaphalafini ipuleti. Ngaphakathi nje leli fu ngomlilo kube nguye division yaba izingxenye ezintathu:

• ingxenye Dark isebangeni eduze izitofu: akukho esivuthayo ngenxa yokushodelwa umoya, futhi izinga lokushisa zone kwaba 350 °.
• ingxenye Bright elele maphakathi ithoshi: igesi ashisayo ukufuthelana kuze kufinyelele 700 °, kodwa uphethiloli is zishe ukuphela akukabikho ngenxa yokuntuleka oxidant.
• Ayevumela ingxenye engenhla: izinga lokushisa ifinyelela 900 °, kanye amandla omlilo ephelele igesi.

Izinombolo umlilo fu elinobuthi esishintshashintshayo ezishisayo ziboniswa adla i-methane.

Imithetho Ukuphepha labadubuli imicimbi

Ukuqala okufanayo, iziko, igesi isitofu, unakekele egumbini ukupholisa. Qinisekisa ukuthi ukugeleza oxygen nophethiloli.

Ungazami ukulungisa imishini igesi bebodwa. Negesi akakubekezeleli nayizimfundamakhwela.

Omuny bathi ithoshi ovuthayo e blue, kodwa ngezinye izikhathi ukukhanya uphendulela orange. Leli akulona global lokushisa ushintsho. Ushintsho umbala ngenxa yezinguquko fuel kwengoma. methane ehlanzekile burns kungekho nto enemibala emihle futhi ayinaphunga. Ngezinjongo zokuphepha, e igesi ukupheka ingezwe nesibabule, okungukufa ngesikhathi omlilo of igesi ngemibala shades blue futhi yazisa imikhiqizo omlilo of iphunga isici.

Ukubukeka anemibala olintshi yellow endaweni apheke kubonisa ukuba zokuvimbela zokukhwabanisa ipuleti. Iseluleki uyosihlanza imishini ukususa uthuli insila okuyinto kuvuthe futhi ukushintsha umbala evamile lomlilo.

Ngezinye izikhathi ngomlilo ngo sikaphalafini bomvu. Lokhu isignali esiyingozi okuqukethwe carbon monoxide e imikhiqizo amandla omlilo. umoya-mpilo uphethiloli incane kangangokuthi ngisho isitofu uyaphuma. I-carbon monoxide ayinaphunga, kunganambitheki, futhi abantu eduze umthombo ekushayweni izinto eziyingozi uzophawula sekwephuze kakhulu ukuthi wadliswa ushevu. Ngakho-ke, i-gas obomvu kudinga ucingo ngokushesha ukuze kuvikelwe amakhosi abeke imishini.
