Cov ntsiab lus hauv qab no yuav tsum tau sau tseg thaum siv cov khoom siv hlau sib xyaw:
Nto huv thiab cov pinholes: qhov saum npoo ntawm cov hlau sib xyaw hlau ntawv yuav tsum tau ceev thiab pub dawb ntawm cov roj thiab hmoov av. Lub nro kom nruj yuav tsum ncav cuag 72mn / m lossis ntau dua, uas tuaj yeem kuaj xyuas los ntawm cov dej dej distilled. Tus naj npawb ntawm pinholes yuav tsum tau tswj nyob rau qee qhov ntau. Piv txwv li, rau txhuas ntawv ci nrog lub thickness ntawm 9um, tus naj npawb ntawm cov pinholes, thiab lub aperture ntawm tus pinholes ntawm tus pinholes yuav tsum tsis txhob loj dua 20um.
Kev Cia Mob Cia Muag Khoom: Txhuas Ntawv Nyiaj yuav tsum muab khaws cia rau hauv lub xeev qhuav thiab zam kev nres ntev kom tiv thaiv kev nqus dej noo thiab oxidation. Nws yuav tsum tau siv kom sai li sai tau ua ntej siv kom tsis txhob noo noo nqus thiab oxidation.
Kev sib koom ua ke thiab kev sib koom ua ke thaum lub sijhawm teeb tsa: Thaum {{mm mm experved sib koom tes yuav tsum tau tseg los ntawm kev nthuav dav los ntawm thermal expansion thiab condaction. Qhov dav dav ntawm kev sib koom tes yuav tsum tsis pub tsawg tshaj 15 mm los xyuas kom meej.
Txij Nkawm thiab Pov Tseg: Tshawb xyuas cov oxidation saum npoo tsis tu ncua. Yog tias qhov oxidation cheeb tsam ntawm cov txheej hlau tshaj 30%, nws yuav tsum tau hloov nyob rau lub sijhawm. Cov khib nyiab yuav tsum tau faib thiab rov ua dua tshiab, thiab cov hlau yuav luag thiab rov ua dua tshiab.
