Pom hauv qhov tsaus ntuj nti li thaum nruab hnub yog qhov npau suav thaum yau ntawm txhua tus tub hluas. Koj pom, tab sis tsis muaj neeg pom koj! Qhov no ua tau yog tias muaj cov cuab yeej ua kom pom kev hmo ntuj. Tab sis NVG tuaj yeem tsim ntawm tes, hauv tsev! Txhawm rau ua qhov no, koj tsuas yog yuav tsum nco qab txog tsev kawm ntawv cov chemistry cov tshooj lus.
Nws yog qhov tsim nyog
- - muffle lossis hluav taws xob cua sov;
- - luv tsom teeb tsom;
- - biconvex lens;
- - cov tshuaj thiab cov pov thawj los ntawm lub tsev kawm ntawv tshuaj lom neeg.
Cov Lus Qhia
Kauj ruam 1
Muab ob lub khob iav tso rau hauv cov khoom sib xyaw ua ke ntawm sulfuric acid (H2SO4) thiab potassium dichromate (K2Cr2O7). Qhuav tom qab 4 teev.
Tso tin chloride (SnCl2) tso rau hauv lub lauj kaub plooj (porcelain) thiab qhov chaw tso rau hauv cov cua sov. Thaum tsis muaj lub hnab looj tes, koj tuaj yeem siv hluav taws xob ua cua sov. Txhim kho cov iav ntawm qhov deb ntawm 8-10 cm saum lub khob. Npog lub khob nrog ib lub phaj hlau.
Thaum qhov kub nyob hauv qhov cub nce rau 400-480 degrees, tshem tawm cov phaj hlau. Ib qho xim ci heev xim coj xim sai sai ua rau ntawm cov tsom iav.
Kauj ruam 2
Tom qab ntawd, tus kws thaij daim duab yuav tsum tau thov rau ib daim phiaj.
Nws tau npaj los ntawm fusing sib npaug sib npaug ntawm cov tshuaj 3% ntawm thio-carbomide Na4 C (S) NH2 thiab cov hmoov txhuas (6% kev daws). Siv cov kua roj vanish rau ntawm ib sab ntawm lub phaj, pub dawb los ntawm cov txheej txheem conductive, tom qab ntawd ntsug, siv cov tweezers, poob rau hauv cov tshuaj tov.
Tam sim no, nco ntsoov hnav cov hnab looj tes roj hmab, nchuav cov tshuaj alkali tov rau hauv lub nkoj nrog lub phaj thiab do maj mam muab nrog cov pas nrig iav, tsis kov lub phaj.
Tom qab li 10 feeb, tshem tawm ntawm lub phaj thiab ntxuav nws kom huv hauv dej distilled. Qhuav nws.
Tso lub khob huv Suav rov qab rau hauv qhov cub, tam sim no nrog nyiaj, thiab tso cov phaj los kho dua nws. Rov qab ua cov txheej txheem, tsuas yog tam sim no nce qhov kub mus rau 900 degrees. Ua tiav daim iav-zoo li zaj duab xis ua rau lub phaj.
Kauj ruam 3
Npaj lub qhov cub dua kom ua phosphor rau ntawm lub phaj thib ob. Lub sijhawm no, muab cov nplai tooj liab thiab ZnS iav ci rau hauv cov khob plooj (veneers) hauv qhov sib npaug: ZnS - 100%, Cu (tooj liab) - 10%. Cov txheej txheem ntawm cov pa hluav taws xob tooj liab thiab lawv cov kis ntawm muaju yuav tshwm sim hauv qhov cub tawg. Tsis txhob zom cov muaju txuas ntxiv. Qhov tshwm sim yuav tsum yog tsis muaj xim tsis muaj hmoov.
Kauj ruam 4
Tam sim no sib tov cov zaponlak nrog cov muaju. Ncuav qhov sib tov sib xyaw tso rau ib lub phaj nrog txheej nyiaj.
Thaum cov dej sib tov sib kis tag thiab ib qho chaw tiaj tiaj tau tsim, muab daim ntawv thib ob tso saum cov kua roj vanish thiab nyem kom maj mam.
(Nco ntsoov cam cam cov nyob ib ncig ntawm cov npoo ntawm daim hlau tom qab thov cov xim conductive).
Leem cov khoom ua kom pom yav hmo ntuj.
Kauj ruam 5
Sau ua ke ntawm lub siab siv hluav taws xob hauv tshuab hluav taws xob.
Kauj Ruam 6
Sib dhos lub cuab yeej nws tus kheej. Lo ntsiab muag rau nws tuaj yeem yog lub lens ntawm txhua lub koob yees duab luv luv; ib lub koob yees duab biconvex tuaj yeem siv ua qhov muag tsom.
Tom qab sib dhos kawg, xyuas txhua qhov kev sib txuas ntxiv thiab rov qab qhib. Ntawm koj NVG qhov hloov pauv yuav ntsiag to beep - nws ua haujlwm.
Daim duab yuav tsis tshwm sim tam sim ntawd. Hloov lub tshuab hluav taws xob zaus, theem voltage. Teem qhov rhiab siab mus rau qhov siab tshaj plaws.
Thiab - siv nws.
