Mafotokozedwe Akatundu

Mawaya okana awa a enameled akhala akugwiritsidwa ntchito mofala ngati zopinga wamba, magalimoto
mbali, mapiringidzo resistors, etc. ntchito kutchinjiriza processing koyenera kwambiri ntchito zimenezi, kutenga mwayi wapadera wa enamel ❖ kuyanika.

Kuphatikiza apo, tidzapanga zokutira za enamel za waya wamtengo wapatali wachitsulo monga siliva ndi waya wa platinamu polamula. Chonde gwiritsani ntchito kupanga-pa-oda.

Mtundu Wa Bare Alloy Waya

Aloyi titha kuchita enamelled ndi Copper-nickel aloyi waya, Constantan waya, Manganin waya. Kama Waya, NiCr Aloyi waya, FeCrAl Aloyi waya etc aloyi waya

Kukula:

Waya wozungulira: 0.018mm ~ 2.5mm

Mtundu wa kutchinjiriza enamel: Red, Green, Yellow, Black, Blue, Nature etc.

Riboni Kukula: 0.01mm * 0.2mm ~ 1.2mm * 5mm

Moq: 5kg kukula kulikonse

Copper Kufotokozera:

Mkuwandi mankhwala okhala ndi chizindikiroCu(kuchokera ku Latin:kapu) ndi nambala ya atomiki 29. Ndi chitsulo chofewa, chosungunula, ndi ductile chokhala ndi matenthedwe apamwamba kwambiri ndi magetsi. Malo owonekera kumene a mkuwa woyera ali ndi mtundu wofiira-lalanje. Mkuwa umagwiritsidwa ntchito ngati kondakitala kutentha ndi magetsi, monga zomangira, ndi constituent a mitundu yosiyanasiyana ya zitsulo aloyi, monga siliva sterling ntchito zodzikongoletsera, cupronickel ntchito m'madzi hardware ndi ndalama, ndi constantan ntchito kupsyinjika gauges ndi thermocouples. kwa kuyeza kutentha.

Mkuwa ndi chimodzi mwa zitsulo zochepa zomwe zimatha kuchitika m'chilengedwe mu mawonekedwe achitsulo ogwiritsidwa ntchito mwachindunji (zitsulo zamtundu). Izi zinapangitsa kuti anthu ayambe kugwiritsidwa ntchito m'madera angapo, kuyambira c. 8000 BC. Zaka masauzande pambuyo pake, chinali chitsulo choyamba kusungunuka kuchokera ku miyala ya sulfide, c. 5000 BC, chitsulo choyamba kuponyedwa mu mawonekedwe mu nkhungu, c. 4000 BC ndi chitsulo choyamba kuti dala alloyed ndi chitsulo china, malata, kupanga mkuwa, . 3500 BC.

Zosakaniza zomwe anthu ambiri amakumana nazo ndi mchere wamkuwa (II), womwe nthawi zambiri umapereka mitundu ya buluu kapena yobiriwira ku mchere monga azurite, malachite, ndi turquoise, ndipo akhala akugwiritsidwa ntchito kwambiri komanso mbiri yakale ngati utoto.

Mkuwa womwe umagwiritsidwa ntchito m'nyumba, nthawi zambiri pakufolera, umathiridwa ndi okosijeni kuti upange verdigris wobiriwira (kapena patina). Mkuwa nthawi zina umagwiritsidwa ntchito muzojambula zokongoletsa, zonse mu mawonekedwe ake achitsulo komanso mumagulu ngati inki. Mankhwala amkuwa amagwiritsidwa ntchito ngati bacteriostatic agents, fungicides, ndi zoteteza nkhuni.

Mkuwa ndi wofunikira kwa zamoyo zonse monga mchere wopatsa thanzi chifukwa ndi gawo lalikulu la kupuma kwa enzyme complex cytochrome c oxidase. Mu molluscs ndi crustaceans, mkuwa ndi gawo la magazi pigment hemocyanin, m'malo ndi iron-complexed hemoglobin mu nsomba ndi nyama zina zamsana. Mwa anthu, mkuwa umapezeka makamaka m’chiwindi, minofu ndi mafupa. Thupi lachikulire lili ndi pakati pa 1.4 ndi 2.1 mg wamkuwa pa kilogalamu ya kulemera kwa thupi.
