Mpweya (O2)

Magawo aukadaulo

Mpweyandi mpweya wopanda mtundu komanso wopanda fungo. Ndi mpweya wofala kwambiri wa mpweya. Ponena za ukadaulo, mpweya umachokera mu njira yothira madzi mumlengalenga, ndipo mpweya womwe uli mumlengalenga umakhala pafupifupi 21%.MpweyaNdi mpweya wopanda mtundu komanso wopanda fungo wokhala ndi formula ya mankhwala O2, yomwe ndi mtundu wofala kwambiri wa mpweya. Malo osungunuka ndi -218.4°C, ndipo malo owira ndi -183°C. Siwosungunuka mosavuta m'madzi. Pafupifupi 30mL ya mpweya imasungunuka mu 1L yamadzi, ndipo mpweya wamadzimadzi ndi wabuluu. Makhalidwe a mpweya ndi ochulukirapo. Kupatula mpweya wosowa ndi zinthu zachitsulo zomwe zimakhala ndi ntchito yochepa monga golide, platinamu, ndi siliva, zinthu zambiri zimatha kuchita ndi mpweya. Mayankho awa amatchedwa ma oxidation reactions. Ma Redox reactions amatanthauza ma reactions omwe ma elekitironi amasamutsidwa kapena kusunthidwa. Mpweya wa okosijeni uli ndi mphamvu zoyatsira ndi kuoxidation. Mpweya wamankhwala umagwira ntchito yofunika kwambiri pachipatala ndi chisamaliro chachipatala, monga kutsitsimutsa, opaleshoni, ndi machiritso osiyanasiyana. Mpweya wa okosijeni ungagwiritsidwenso ntchito ngati mpweya wopumira posambira mutasakanikirana ndi nayitrogeni kapena helium. Mpweya wamalonda ungapezeke poyetsa ndi kusungunula mpweya m'chilengedwe mufakitale yolekanitsa mpweya. . Ntchito yayikulu ya mafakitale ya mpweya ndi kuyaka. Zipangizo zambiri zomwe nthawi zambiri sizimayaka mumlengalenga zimatha kuyaka mu mpweya, kotero kusakaniza mpweya ndi mpweya kumathandizira kwambiri kuyaka bwino m'mafakitale achitsulo, zitsulo zopanda chitsulo, magalasi ndi konkire. Pambuyo posakaniza ndi mpweya wamafuta, imagwiritsidwa ntchito kwambiri podula, kuwotcherera, kupangira zitsulo ndi kupukutira magalasi kuti kutentha kukhale kwakukulu kuposa kuyaka kwa mpweya, zomwe zimapangitsa kuti zinthu ziyende bwino. Malangizo Osungira: Sungani m'nyumba yosungiramo zinthu yoziziritsa komanso yopuma mpweya. Sungani kutali ndi moto ndi magwero a kutentha. Kutentha kosungirako sikuyenera kupitirira 30°C. Kuyenera kusungidwa padera ndi zinthu zomwe zimayaka, ufa wachitsulo wogwira ntchito, ndi zina zotero, ndipo pewani kusungirako kosakanikirana. Malo osungiramo zinthu ayenera kukhala ndi zida zochizira mwadzidzidzi zomwe zimatuluka.

Ntchito:

①Kugwiritsa Ntchito Makampani:

Kupanga zitsulo, kusungunula zitsulo zopanda chitsulo. Kudula zitsulo.

②Kugwiritsa Ntchito Pachipatala:

Popereka chithandizo choyamba chadzidzidzi monga kupuma movutikira ndi matenda a mtima, pothandiza odwala omwe ali ndi matenda opuma komanso oletsa kupweteka.

③Kupanga Semiconductor:

Kuyika kwa nthunzi ya silicon dioxide m'thupi, kukula kwa thermal oxide, kupukutira kwa plasma, kuchotsa photoresist m'magazi ndi mpweya wonyamula m'magazi m'machitidwe ena oika/kufalitsa.

Phukusi lachizolowezi:

Ubwino:

①Zaka zoposa khumi pamsika;

②Wopanga satifiketi ya ISO;

③Kutumiza mwachangu;

④Magwero okhazikika a zinthu zopangira;

⑤Njira yowunikira pa intaneti yowongolera khalidwe pa sitepe iliyonse;

⑥Kufunika kwakukulu komanso njira yosamala yogwiritsira ntchito silinda musanadzaze;
