Tsis tshua muaj hluav taws kub sib txawv nplaim taws

Hluav Taws kub ua lub teeb tshiab rau saib li ib txwm tej yam uas - flashed dawb match, lub xiav glow ntawm lub burner roj qhov cub nyob rau hauv lub chav ua noj, txiv kab ntxwv-liab tongues ntawm nplaim ntoo. Tus txiv neej tsis tau them nyiaj mloog rau qhov hluav taws kub kom txog thaum lawv hlawv lub tswv yim ntawm nws tus ntiv tes. Los yog puas tau pw tsis tsaug zog lub qos yaj ywm nyob rau hauv lub yias. Los yog prozhzhot qab xib khau ntaub, kom qhuav tshaj qhov hluav taws kub.

Thaum tus thawj mob, kev ntshai thiab ntxhov siab yog, nws yog lub sij hawm mus philosophical thiaj. Qhov xwm, xim, kub, hluav taws kub.

Nws lit zoo li ib tug match

Luv luv txog cov qauv ntawm cov match. Nws muaj nrog thiab lub taub hau. Lub sticks no yog ua los ntawm cov ntoo, cov duab los qhia thiab paj rwb cab, impregnated nrog paraffin. Ntoo xaiv softwood - Poplar, ntoo thuv, Aspen. Raw cov ntaub ntawv rau tus pas no yog hu ua ib tug match sticks. Kom tsis txhob noj nyiaj txiag straws, nrog impregnated nrog phosphoric acid. Lavxias teb sab factories sticks carved los ntawm Aspen.

Head Match yog yooj yim nyob rau hauv daim ntawv tiam sis complex nyob rau hauv lawv cov tshuaj nyob tus yeees. Tsaus xim av match lub taub hau muaj xya Cheebtsam: oxidizing - bertoletova ntsev thiab poov tshuaj dichromate; steklyannyuu hmoov av minium ntawm hmoov txhuas, cov leej faj, cov pob txha kua nplaum, zinc dawb.

Head Match Cov nroj cig cuag los ntawm kev sib txhuam, rhuab mus rau ib tug txhiab degrees. Ignition pib nyob rau hauv degrees Celsius :

• Poplar - 468;
• Aspen - 612;
• Ntoo thuv - 624.

Tsis tshua muaj hluav taws kub match sib npaug zos rau qhov kub thiab txias ntawm ignition ntawm tus ntoo. Yog li ntawd, ib tug dawb flash lub taub hau yog hloov nrog sulfuric daj-txiv kab ntxwv tus nplaig qhov yuam kev.

Yog hais tias koj zoo xyuas cov burning match, ces saib yuav tshwm sim peb nplaim taws tsam. Lower - txias xiav. Qhov nruab nrab ib nrab ntau li ntau rhaub. Txheej - kub tsam.

Hluav Taws artist

Thaum lo lus "hluav taws" flash tsis muaj tsawg luj lug nostalgic puas: pa luam yeeb hluav taws, tsim ib trusting ib puag ncig; liab thiab daj teeb ya mus ultramarine ntuj; ua si nrog tongues xiav rau ruby-liab xim; liab hluav ncaig txias down, uas mob siab "Pioneer" qos yaj ywm.

Cov hloov xim ntawm ib tug nplaim hluav taws ua dlejnum hloov mus hloov los nyob rau hauv lub kub ntawm qhov hluav taws kub. ntoo lwj (darkening) pib nrog 150 °. Ignition (taws kub nnyiab ya) tshwm sim nyob rau hauv lub luv 250-300 °. Rau tib lub tsob ntoo hom uas nkag mus rau cov pa hlawv ntawm cov kub. Raws li, qhov degree ntawm cov hluav taws yuav kuj yuav sib txawv. Birch hlawv rau 800 degrees, Alder - ntawm 522 °, thiab cov hmoov tshauv, beech - thaum 1040 °.

Tab sis cov xim ntawm hluav taws kub yog tseem txiav txim los ntawm cov tshuaj muaj pes tsawg leeg ntawm lub burning substance. Daj thiab txiv kab ntxwv nplaim taws ua sodium ntsev. Tshuaj nyob tus yeees muaj cellulose thiab sodium ntsev thiab poov tshuaj ntsev, muab ib tug glowing coals tsob ntoo liab Hawj txawm. Romance xiav teeb nyob rau hauv ib tug hluav taws tshwm sim vim tsis muaj oxygen, es tsis txhob ntawm thaum lub CO ₂ tsim CO - carbon monoxide.

Enthusiasts scientific thwmsim ntsuas qhov kub ntawm qhov hluav taws kub nyob rau hauv qhov hluav taws kub kws hu ua ib tug pyrometer. Manufactures peb hom pyrometers: kho qhov muag, radiation, spectral. Qhov no contactless pab kiag li lawm, uas mus ntsuam xyuas lub peev xwm ntawm lub thermal tawg.

Tej hau kev kawm los ntawm qhov hluav taws kub nyob rau hauv koj tus kheej chav ua noj

Chav tsev mov roj qhovcub khiav nyob rau hauv ob fuels:

1. Tej yam ntuj tso pa roj yog methane.
2. Hluav taws roj zeb-butane sib tov ntawm liquefied gas tso tsheb hlau luam thiab thooj voos kheej kheej.

Cov tshuaj nyob tus yeees ntawm cov roj gas kub txiav txim qhov hluav taws kub phaj. Methane, kub, qhov hluav taws kub tas ib lub peev xwm ntawm 900 degrees nyob rau sab saum toj.

Combustion liquefied sib tov muab tshav kub mus rau 1950 °.

Ib tug ceev faj observer yuav nco ntsoov sis tsis ncaj coloring tongues roj burner phaj. Hauv qhov hluav taws kub plume yog lub division rau hauv peb aav:

• Tsaus feem positioned nyob ze ntawm lub burners: muaj yog tsis muaj burning vim tsis muaj oxygen, thiab cov cheeb tsam kub yog 350 °.
• Kaj feem dag nyob rau hauv qhov chaw ntawm lub teeb: kub roj yog rhuab mus rau 700 °, tab sis lub roj burnt mus txog thaum kawg yog tsis vim tsis muaj oxidant.
• Translucent sab sauv feem: qhov kub thiab txias nce mus txog 900 °, thiab ib tug ua kom tiav combustion ntawm roj.

Nuj nqis hluav taws plume thermal aav muaj qhia rau methane.

Safety kev cai rau firing cov txheej xwm

Igniting qhov yuam kev, qhov cub, roj qhov cub, saib xyuas ntawm lub chav tsev cua. Xyuas kom meej tias cov ndlwg ntawm oxygen mus rau lub roj.

Tsis txhob sim kho cov roj cov khoom rau lawv tus kheej. Gas tsis tso amateurs.

Hostess hais tias lub teeb zes nyob rau hauv xiav, tab sis tej zaum lub teeb puv txiv kab ntxwv. Qhov no yog tsis yog ib tug ntiaj teb no kub hloov. Cov xim kev hloov no yog vim cov kev hloov nyob rau hauv roj muaj pes tsawg leeg. Ntshiab methane Burns tsis muaj kob thiab ntxhiab. Kev ruaj ntseg cov hom phiaj, nyob rau hauv ua noj ua haus roj ntxiv cov leej faj, uas thaum lub sij hawm lub combustion ntawm roj nyob rau hauv cov xim xiav ntxoov thiab qhia lub combustion khoom ib tug yam ntxwv tsis hnov tsw.

Cov tsos ntawm cov txiv kab ntxwv thiab daj hues nyob rau hauv ib tug tua hluav taws ua noj ua haus tsam qhia rau tiv thaiv manipulation phaj. Wizard yuav ntxuav khoom mus tshem tawm cov hmoov av thiab av uas hlawv thiab hloov qhov ib txwm xim ntawm cov hluav taws.

Tej zaum qhov hluav taws kub nyob rau hauv lub burner puv liab. Qhov no teeb liab txaus ntshai carbon monoxide cov ntsiab lus nyob rau hauv lub combustion khoom. mov ntawm oxygen mus rau cov roj yog li ntawd me me hais tias txawm lub qhov cub mus tawm. Carbon monoxide yog muaj ntxhiab, cov mov, thiab cov neeg nyob ze mus rau qhov chaw ntawm emission ntawm teeb meem tshuaj yuav pom lig dhau lawm uas tau kuab lom tau. Yog li ntawd, cov liab roj yuav tsum tau ib tug tam sim ntawd hu rau tus tiv thaiv ntawm masters thiab teeb li khoom.
