Mpweya (O2)

Magawo aukadaulo

Mpweyandi mpweya wopanda mtundu komanso wopanda fungo. Ndi mpweya wofala kwambiri wa mpweya. Ponena za ukadaulo, mpweya umachotsedwa mu njira yothira mpweya, ndipo mpweya womwe uli mumlengalenga umakhala pafupifupi 21%. Mpweya wa oxygen ndi 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. Susungunuka mosavuta m'madzi. Pafupifupi 30mL ya mpweya imasungunuka mu 1L yamadzi, ndipo mpweya wamadzimadzi ndi wabuluu. Makhalidwe a mankhwala a mpweya amagwira ntchito kwambiri. Kupatula mpweya wosowa komanso zinthu zachitsulo zomwe zimakhala ndi ntchito yochepa monga golide, platinamu, ndi siliva, zinthu zambiri zimatha kuchita ndi mpweya. Machitidwe awa amatchedwa ma oxidation reactions. Ma Redox reactions amatanthauza ma reactions omwe ma elekitironi amasamutsidwa kapena kusunthidwa. Mpweya wa oxygen uli ndi mphamvu zothandizira kuyaka komanso kupangitsa kuti pakhale okosijeni. Mpweya wachipatala umagwira ntchito yofunika kwambiri pachipatala ndi chisamaliro chachipatala, monga kubwezeretsanso mpweya, opaleshoni, ndi mankhwala osiyanasiyana. Mpweya wa okosijeni ungagwiritsidwenso ntchito ngati mpweya wopumira posambira pambuyo poti wasakanizidwa ndi nayitrogeni kapena heliamu. Mpweya wamalonda ungapezeke mwa kusungunula ndi kusungunula mpweya womwe uli m'chilengedwe mufakitale yolekanitsa mpweya. . Ntchito yaikulu ya mpweya m'mafakitale ndi kuyaka. Zinthu 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. Mukasakaniza ndi mpweya wamafuta, umagwiritsidwa ntchito kwambiri podula, kuwotcherera, kupangira chitsulo ndi kupukutira magalasi kuti upereke kutentha kwakukulu kuposa kuyaka kwa mpweya, motero umawonjezera kugwira ntchito bwino. Malangizo Osungira: Sungani m'nyumba yosungiramo zinthu yozizira, yopuma mpweya. Sungani kutali ndi moto ndi magwero otentha. 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;
