X - duab liab zaj duab xis yog cov siv uas siv tau hauv kev kuaj mob. Nws muaj tag nrho cov tuab ntawm kwv yees li 0.5 hli thiab muaj xya txheej:
* a. Hardened Gelatine Txheej
b. Emulsion Txheej
c. Substratum (Kev Ua Haujlwm Txheej)
d. Cellulose triacetate lossis polyester puag
Schematic Hla -} seem ntawm ib x - cov duab dhos ua ntej {}} hli:
Cov yeeb yaj kiab tus tub ntxhais yog pob tshab cellulose triacetate lossis polyester puag (d). Coated ntawm ob sab yog:
• Ib txheej txheej ntawm cov tawv nqaij tawv tawv (a), uas tiv thaiv cov emulsion.
• Ib txheej emulsion (b), uas yog hluav taws xob - rhiab emulsion tshem tawm hauv lub gelatin.
• Ib txheej nyias nyias hu ua substratum (c), uas khi cov txheej emulsion rau lub hauv paus.
Yog li ntawd, X - ray zaj duab xis, uas muaj ob zaug emulsion txheej, muaj ob zaug ceev ntawm zaj duab xis nrog tsuas yog ib qho emulsion txheej. Kev thaij duab emulsion yog ib qho kev nkag siab rau ionizing hluav taws xob thiab lub teeb, muaj cov nyiaj hallocrystalline cais nyob rau hauv gelatin.
Nco tseg: Yav dhau los, nws tsis yooj yim los ua ntawv convoraphy ntawm daim ntawv. Hauv qhov "ua kom sai sai" txheej txheem, tshwm sim tau muaj nyob hauv 60 vib nas this.
