Ubwino wanji wamapali owunikira mumsewu wa LED kuposa mizati yachikhalidwe? Ubwino waukulu wa mizati ya kuwala kwa mumsewu wa LED ndikuti mtengo wopangira ndi wotsika mtengo kuposa nyali zamumsewu komanso kuwala kowala kwambiri. Komabe, nyali zothamanga kwambiri za sodium sizothandiza zachilengedwe komanso zopulumutsa mphamvu ngati nyali zapamsewu za LED. Kuwala ndi mitundu sizokongola.

Mukayika nyali zamsewu za sodium mumsewu, ndikofunikira kukumba ngalande ndi mawaya ophatikizika, zomwe zimawonjezera mtengo woyika ndi kukonza. Chifukwa chake, nyali zapamsewu zothamanga kwambiri za sodium zidzachotsedwa pang'onopang'ono ndi nyali zapamsewu za LED. Poika mizati yowunikira mumsewu, chidwi chiyenera kulipidwa ngati mawaya ali otayirira, kaya kugwirizana pakati pa kondakitala pansi ndi mzere waukulu wabwereranso, kapena ngati woyendetsa pansi amawombana ndi woyendetsa pansi pamene akugwira ntchito pamtengo wounikira.

Yang'anani ngati mbali yowunikira ya kuwala kwa msewu wa dzuwa ndi yolondola, ngati bulaketi ya nyali yakhazikika, ndipo samalani ndi kusuntha kwapambuyo kapena kutsika kwa mkono wa nyali. Pambuyo poyika magetsi onse a mumsewu wa LED ndi magetsi a dzuwa a mumsewu, yesani nyali, fufuzani mphamvu yamagetsi, yesani nyali, ndikusinthanso mbali yowunikira ya nyali. Mizati yowunikira mumsewu iyenera kusamalidwa pafupipafupi.

Ngati pali vuto lililonse, mtengo wowunikira uyenera kusinthidwa ngati sungathe kukonzedwa. Pamwamba pa mtengo kuwala ayenera degreased pamaso pickling. Zilowerereni mu thanki yothira mafuta kwa mphindi 15-30, kenaka muzitsuka mu thanki yoyeretsera kupitilira kawiri.

Kenako, sambani oxide wosanjikiza pamwamba pa nyali ndi hydrochloric acid kwa mphindi 20-40. Ngati pali wosanjikiza wa oxide pamtunda, iyenera kuthandizidwa ndi zida, ndikuzifutsa kwa mphindi 15. Pambuyo pa pickling, ma ion a asidi pamtunda wa nyali ayenera kuchotsedwa mu thanki yamadzi yoyera, ndipo mafupipafupi oyeretsa ayenera kukhala oposa 2.
