Yuav ua li cas yuav ua rau ib tug sparkler tom tsev: muaj pes tsawg leeg thiab technology

Sparklers - ib tug indispensable attribute ntawm tej kev lom zem nyiaj so koobtsheej - Xyoo tshiab, ib xyoos (thiab tsis tau tsuas yog cov me nyuam) tshoob. Lawv raug nqi ib penny, muag qhov txhia chaw, nws yog kiag li muaj kev nyab xeeb rau sab hauv tsev tiv cav tseb. Txawm li cas los, cov neeg tseem mus txuas ntxiv yuav tsum tau xav nyob rau hauv yuav ua li cas yuav ua rau ib tug sparkler tom tsev: los tsim nrog cov me nyuam muaj kev xyiv fab ntawm cov yeeb yuj thiab nthuav, thiab tsub kom lub anticipation ntawm cov nyiaj so koobtsheej. Qhov ntau li vim hais tias cov txheej txheem nws tus kheej yog yooj yim, thiab qhov tsim nyog ntaub ntawv yog npaj meej muaj nyob.

zaub mov txawv compositions

Craftsmen tau tuaj mus nrog ob peb txoj kev ua kom ib tug sparkler rau lawv tus kheej. Nyob ntawm seb dab tsi koj tau yooj yim, koj yuav xaiv ib yam ntawm cov zaub mov txawv. Ib pab pawg neeg no muaj xws li compositions uas yog yuav tsum tau 50% los ntawm qhov hnyav ntawm barium nitrate thiab 12-14 feem pua dextrin. Ntxiv cov khoom xyaw tej zaum yuav xaiv los ntawm cov nram qab no daim ntawv teev:

1. Los ntawm 6 mus rau 8% ntawm ib tug zoo hmoov txhuas ntxiv rau 30% sawdust - Yuav Tsum thiab burnished hlau.
2. Rau lub hauv paus yog ntxiv tib yam pes tsawg tus ntawm zoo xws li cov chips, thiab hmoov yog hloov los ntawm Pam № 4 - yog ib tug tsiaj ntawv ntawm txhuas-magnesium hmoov.

Tag nrho cov kev xaiv yog zoo vim hais tias lawv muaj tsis muaj poov tshuaj ntsev / sodium, tsis muaj leej faj, yog li ntawd cov pa luam yeeb yuav tsis muab cov taws tswm ciab, raws li zoo raws li tag nrho cov hom ntawm toxins. Tshwm sim: lub teeb yuav siv tau nyob rau hauv lub tsev tsis muaj kev ntshai ntawm lom.

Lwm pes tsawg leeg muaj ib tug radically txawv formulation. 6-8 teeb coj txhuas hmoov uas 5 grams, dextrin - 2 grams thiab sawdust, lub sij hawm no cam khwb cia hlau, uas yuav muab 5 mus rau 6 g Cov teeb yuav tsum tau siv tawm sab nraud xwb.

Muab cov kev tsim nyog cov khoom xyaw

Yuav ib co ntawm cov yam tshuaj tsis yeej ib txwm ua hauj lwm. Yog li ntawd ua ntej ua ib tug sparkler nyob rau hauv lub tsev, tej zaum yuav tau pib npaj lub Cheebtsam. Qhov yooj yim txoj kev yog cov ntaub ntawv nrog dextrin: nws yog tsim thaum rhuab nyob rau hauv lub qhov cub rau pa hmoov txhuv nplej. Kub yog teem rau ntawm 195 Celsius, ua yog ua kom tau lub pib cov ntaub ntawv uas brownish Hawj txawm.

Yog hais tias koj yog nyob rau ib daim ntawv qhia nrog txhuas hmoov, nws yuav tau ua tawm sab nraud. Lub mortar pulverized txhuas hmoov, poov tshuaj nitrate thiab leej faj nyob rau hauv proportions 30:45:25.

Tseem ceeb: hlau

Nws yog ib nqi them sai sai mus thiab lub hauv paus rau cov uas koj yuav khaws koj cov "foob pob hluav taws." Ntawm no, ib yam nkaus thiab, muaj ib tug ob peb subtleties. Firstly, ntev: txiav cov hlau lengths ntawm tsawg kawg yog 14 cm yog li ntawd koj yuav tiv thaiv ob txhais tes ntawm sparks los yog kub muaj pes tsawg leeg .. Secondly, qhov tuab. Siv ib tug hlau nrog ib tug ntoo khaub lig seem ntawm 2-3 hli. Lub thinner yuav hlawv thiab puas. Peb, cov khoom. Tsis yog tus twg tooj liab los yog txhuas yog tsis haum - mixtures combustion kub siab heev, thiab lawv cia li melted. Saib steel hlau. Thiab tsis txhob hnov qab yuav ua li cas yuav ua rau sparkler tsev, khoov ib kawg mus rau hauv ib tug nuv li koj muaj peev xwm dai kom qhuav. Yog hais tias koj khoov yuav yam, nws tom qab yuav straightened los yog skusit.

Yuav ua li cas yuav ua rau ib tug sparkler tus kheej ob txhais tes: cov lus qhia

Tsis tag li ntawd cov tshuaj thiab rods, koj yuav tsum tau ib lub taub ntim rau hauv uas mus npaj muaj pes tsawg leeg. Thawj, muaj yog poured ib tug txhuas hmoov los yog lub barium ntsev, ces - dextrin, thiab tsuas yog tom qab stirring - cov seem yam ntawm lub sib tov. Thaum lub qhuav hmoov yog kneaded kom txog thaum uniform txog, nws ntws me ntsis hnyav (muaj - dej, tab sis zoo dua cawv). Lub taub hau yuav tsum zoo li ib tug hau condensed mis nyuj. Qhov ntev ntawm lub hlau uas nws txo qis rau hauv lub tawm rau lub "lis" ntawm 5-7 cm. Cov yav tom ntej sparkler dai kom qhuav nyob rau hauv ib tug peb lub hlis twg ntawm ib teev, tom qab uas lub manipulation yog pheej rov qab ua ob zaug ntxiv. Lub peb khaubncaws sab nraud povtseg yog mus rau qhuav rau ib nrab ib teev, thiab ces thov ob twb tau piav yam. Qhov kawg kom qhuav yuav siv sij hawm ib nrab ib hnub, thiab muaj peev xwm yuav teem on hluav taws.

lwm txoj kev

Feem ntau cov neeg siv ib tug me ntsis txawv cov txheej txheem, yuav ua li cas yuav ua rau sparkler nyob rau hauv tsev. Thawj brewed khov kho muab tshuaj txhuam ntawm starch thiab kais dej. Ces frays caws nplaum sib tov uas muaj xws li me me feem ntawm hlau plua av, magnesium hmoov (raws li ib qho kev xaiv - txhuas), thiab ua noj ua haus ntsev bertoletova. Nrog qhov tseeb yuav tsum muaj leej twg ua tib zoo, thiab ua ntej vsypaniem ntsis ntub nws. Cov sib tov twb kneaded nyob rau hauv brewed rau cov hmoov txhuv nplej smoothness. Nyob rau hauv tib txoj kev hauv lub tiav lawm dipped rods nrog lub sij hawm ua mib ntawm daim ntawv thov ntawm khaubncaws sab nraud povtseg.

kob sparks

Cov neeg uas tsis yog ib yam nkaus thiab tub nkeeg mus tinker ib me ntsis, yuav muab ib txoj kev mus ua ib tug sparkler nyob rau hauv tsev, muab ib tug txawv txawv "ciav". Yog xav tau nplaim taws greenish zas tas tswm ciab ywg dej barium ntsev (nitrate los yog monochloride). Yuav kom tiv thaiv tau lawv los ntawm fraying sparkler tsuag lo-tshuaj tsuag. Liab sparks xav tau strontium nitrate hmoov, uas yog ua ntej rau daim ntawv thov yuav tsum zoo qhuav. Ib tug xiav teeb yuav zes, yog hais tias lawv ua lub tooj liab oxide tov nrog tooj liab azure nyob rau hauv tus piv 5: 3.
