Tam sim no, lo lus nug ntawm yuav ua li cas rau kev nplua nyiaj ntawm cov ntawv ci yog qhov muaj feem xyuam, txij li lawv tau siv dav hauv cov chaw me me rau menyuam yaus, ntau yam dej num ntawm cov neeg laus thiab cov nroog ua koob tsheej.
Cov npas cov npas yog tsim los ntawm cov khoom siv ntawm cov hlau zaj duab xis lavsan, nrog rau daim ntawv thov ntawm cov xim muaj xim lossis cov txheej xim monochromatic, koom nrog lawv los ntawm kev ua haujlwm thermal. Txij li cov lavsan zaj duab xis nrog cov hlau xaim tau zoo heev rau cov ntawv ci, lawv feem ntau hu ua "ntawv ci-txheej", ntau ntau dhau tsawg - "mylar" lossis "lavsan". Cov npas Npas yog cov hom:
- Kev ua kom zoo nkauj - yog tsim nyob rau hauv daim ntawv ntawm ntau lub hnub qub, lub voj voog, lub plawv, lub crescent los ntawm monochromatic zaj duab xis ntawm cov xim qaim. Qee cov tuam ntxhab npog lawv nrog cov xim holographic, uas muab cov xim muaj hlau thiab cov duab ntxoov ntxoo.
- Nrog ib daim duab - lawv tsim tawm hauv cov ntawv zoo ib yam li cov khoom zoo nkauj, tab sis cov duab kos lossis cov ntawv sau yog siv rau lawv rau txhua lub sijhawm ua kev lom zem.
- Cov cim taw qhia yog monochromatic, raws li txoj cai, ua hauv daim ntawv ntawm cov lej lossis ntawv Latin 80-90 centimeters siab.
- Daim duab - ua nyob rau hauv daim ntawv ntawm cov tsiaj, heroes ntawm tas luav thiab cov lus dab neeg, ntau yam khoom. Lawv tuaj yeem yog qhov yooj yim lossis voluminous.
- Cov naj npawb taug kev - hauv lawv muaj qhov hnyav hnyav tshwj xeeb uas tiv thaiv lawv los ntawm ya. Ntawm qhov kev sib tw me me, daim duab txav mus rau hauv pem teb, hloov mus, vuag nws ob txhais npab, twists nws lub taub hau.
Yuav ua li cas thiab yuav ua li cas kom tsim lub pob ntawv ci rau pob?
Cov khoom me me feem ntau muaj huab cua, nyob rau hauv cov ntaub ntawv no lub pob feem ntau txuas nrog lub raj nrog ib daim clip. Cov nqaj txiav ntsuas 18 nti lossis ntau dua yog ntim nrog helium. Txhua lub npas xov ntawm lub hauv paus muaj qhov inlet (aka check) valve, dhau ntawm nws tau ua pa nrog cua thiab helium.
Yuav kom daws tau lo lus nug ntawm yuav ua li cas thiaj li ua kom lub ntsej muag ntawm cov ntawv ci nrog huab cua, koj tuaj yeem siv lub twj tso kua mis, uas muaj ob peb lub suab thiab tsim nyog rau txhua hom. Yog tias lub twj tso kua mis tsis nyob ntawm koj txhais tes, koj tuaj yeem tshuab nrog koj lub qhov ncauj los ntawm txoj yas raj. Hauv qhov no, koj yuav tsum ua tib zoo ntxig rau lub raj xa mus rau hauv qhov nkag mus rau hauv nruab nrab ntawm pob, txav nws 5-10 centimeters sab hauv thiab sab hauv kom sab hauv. Yog tias tsim nyog, ua kom lub pob ntawm cov ntawv ci lossis maj mam thawb lub raj kom tob me ntsis. Tom qab nce nqi, koj tsuas yog yuav tsum rub tawm lub raj xa dej, daim tshev valve yuav kaw tam sim ntawd thiab cua yuav tsis tawm.
Txhawm rau sau cov ntawv ci zais pa nrog helium, koj yuav xav tau lub zais pa helium, zais cov pob thiab txuas ntxiv rau hom zais pa. Qhov qis qis, dav dua ib feem ntawm lub nozzle yog screwed rau lub tog raj kheej, tom qab ntawd tus adapter tau screwed rau hauv nws. Qhov tshwj xeeb no yog lub raj uas yuav tsum tau ua kom zoo ib yam li thaum tshuab nrog huab cua. Nws raug nquahu los tshuab lub zais pa los ntawm lub raj nrog cua ua ntej qhib lub zais pa (tsuas yog ib qho kev tso tawm kom paub tseeb tias huab cua tau ntws). Tom qab ntawd koj yuav tsum nias lub caj dab ntawm lub pob mus rau lub adapter, qhib lub valve ntawm lub tog raj kheej thiab pib sau lub pob. Thaum xub thawj, nws yog inflated sai, tab sis thaum nws yuav luag tag nrho, helium tau pub rau hauv seem me me kom tsis txhob muaj zais pa tawg. Thaum cov ntawv ci zais pa yog kom tiav, tus kais hloov mus kom meej, lub npas yog ua tib zoo muab tshem tawm ntawm cov hloov kho, khi nrog txhav los yog muab khi nrog tus foob.
Lub pob zais pa zoo tsis tas yuav tsum muab txoj hlua khi, raws li daim tshev valve khaws qhov muab tub lim sab hauv. Tab sis kom cov pob tsis txhob ya mus, txhav muab khi los ntawm nws caj dab. Yog tias koj khi txoj hlua xov saum toj sab hauv, ces qhov ceev ntawm lub pob tuaj yeem tsoo thiab pob yuav poob nws cov elasticity, yog li koj yuav tsum khi txoj hlua khi hauv qab cov inlet. Cov pob qhov tsis muaj qhov sib khi tau muab khi siv cov khoom siv tshwj xeeb - cov khoom foob, thaum ob lub welds yog tsim rau ntawm caj dab ntawm lub pob puv, nyob rau sab saud. Tom qab ntawd lub vov hniav khi rau nws.
Lub lifespan ntawm ntawv ci zais pa
Lawv lub neej ncua ntawm ob peb hnub mus rau ib hlis. Helium lossis cua maj mam tawm los ntawm qhov kev ntsuas qhov nrawm lossis dhau ntawm cov nqaws uas txuas cov ntu ntawm lub zais pa.
Ib qho ntxiv, ib puag ncig cuam tshuam lub neej kev cia siab: txias, cua sov, nag. Yog li, nws raug nquahu kom tsis txhob ua rau cov npas zais rau qhov kub hloov pauv, kom tsis txhob siv nyob rau hauv cov nag lossis cua, thiab sau kom zoo thiab khi lawv.
Lub neej thib ob ntawm ntawv ci zais pa
Txhawm rau kom txuag tau nyiaj thaum kho kom zoo nkauj hnub so, koj tuaj yeem rov qab siv cov ntawv ci uas tau siv, tab sis rau qhov no koj yuav tsum ua kom zoo thiab ua tib zoo tso pa txhua qhov ntawm lawv, thiab khaws lawv nthuav rau hauv qhov chaw qhuav thiab txias, tso ntawv ntawm lawv.
