Wareegga Copper ee ku salaysan NicrAlloy 180shahaado Fasalka dahaaran ee silig naxaas ah

1.Sharaxaada Guud ee Agabka

1)

Manganinwaa daawaha sida caadiga ah 84% copper, 12% manganese, iyo 4% nikkel.

Silig Manganin iyo bireed waxaa loo isticmaalaa soo saaridda resistors, gaar ahaan ammeter shunt, sababtoo ah ku dhawaad ​​eber heerkulka iska caabin ah iyo xasilloonida muddada dheer. Dhowr iska caabiyeyaasha Manganin waxay u adeegeen sidii heerka sharciga ah ee ohm ee Maraykanka laga bilaabo 1901 ilaa 1990. Siliga Manganin ayaa sidoo kale loo isticmaalaa sida kirishbooyada ee nidaamyada cryogenic, yaraynta kulaylka u dhexeeya dhibcaha u baahan isku xirka korantada.

Manganin waxa kale oo loo isticmaalaa qiyaasaha daraasaadka mowjadaha shoogga ee cadaadiska sarreeya (sida kuwa ka dhasha qarxinta walxaha qarxa) sababtoo ah waxay leedahay dareen cadaadis hooseeya laakiin dareenka cadaadiska hydrostatic sare.

2)

Constantanwaa daawaha copper-nickel sidoo kale loo yaqaanEureka, HormariyoDoomaha. Caadi ahaan waxay ka kooban tahay 55% naxaas iyo 45% nikkel. Muuqaalkeeda ugu muhiimsan waa iska caabinteeda, kaas oo si joogto ah uga sarreeya heerkul badan oo kala duwan. Alloys-yada kale ee leh isku-xireyaasha heerkulka hooseeya waa la yaqaan, sida manganin (Cu₈₆Mn₁₂Ni₂).

Cabbirka noocyada aadka u weyn, 5% (50 000 microstrian) ama ka sareeya, joogtada la tirtiray (P alloy) waa shayga sida caadiga ah loo doortay. Constantan qaabkani waa mid aad u jilicsan; iyo, dhererka cabbirka 0.125 inji (3.2 mm) iyo ka dheer, waxa lagu cadaadin karaa>20%. Waa in maskaxda lagu hayaa, si kastaba ha ahaatee, in marka la eego culaysyada wareegyada sare ee alwaaxdu ay muujin doonto isbeddelka iska caabinta joogtada ah ee wareeg kasta, oo ay keento isbeddel eber u dhigma ee cabbirka cadaadiska. Sifadan awgeed, iyo u janjeersiga cilad-sheegid degdega ah oo leh cadaadis soo noqnoqda, P alloy caadi ahaan laguma talinayo codsiyada cadaadis wareeg ah. P alloy waxaa lagu heli karaa lambarada STC ee 08 iyo 40 si loogu isticmaalo biraha iyo balaastikada, siday u kala horreeyaan.

2. Hordhac iyo codsiyo silig la magac baxay

In kasta oo lagu tilmaamo inay yihiin “dhalalay”, silig la dahaadhay maaha, dhab ahaan, lagu dahaadhay lakabka ranjiga dhaldhalaalka ama dhaldhalaalka vitreous ee ka samaysan budada dhalada ah ee la isku daray. Siliga magnetka casriga ah wuxuu caadi ahaan u adeegsadaa hal ilaa afar lakab (haddii ay tahay silig nooca afar-filim ah) ee dahaarka aflaanta polymer, inta badan laba qaybood oo kala duwan, si loo bixiyo lakab adag oo joogto ah. Filimada xargaha dahaarka ee Magnet waxay isticmaalaan (sida ay u kordhayaan kala duwanaanta heerkulka) polyvinyl formal (Formar), polyurethane, polyimide, polyamide, polyster, polyester-polyimide, polyamide-polyimide (ama amide-imide), iyo polyimide. Siliga magnetka ee dahaaran ee Polyimide wuxuu awoodaa inuu shaqeeyo ilaa 250 °C. Daboolida silig labajibbaaran oo dhumuc weyn ama leydi leh ayaa inta badan lagu kordhiyaa iyadoo lagu duuduubo heerkul sare oo polyimide ah ama cajalad fiberglass ah, iyo dabaysha la dhamaystiray ayaa inta badan faakuum lagu dhex daraa varnish dahamiya si loo hagaajiyo xoogga dahaarka iyo kalsoonida muddada dheer ee dabaysha.

Gariiradaha iskood isu taageera ayaa lagu dhaawacay silig lagu dahaadhay ugu yaraan laba lakab, kan ugu dambeeyana waa heerkulbeeg isku xidha wareegyada marka la kululeeyo.

Noocyada kale ee dahaarka sida muraayadaha fiberglass leh varnish, warqad aramid, warqad kraft, mica, iyo filimka polyester-ka ayaa sidoo kale si weyn looga isticmaalaa adduunka oo dhan codsiyada kala duwan sida transformers iyo reactors. Qeybta maqalka, silig ah dhismo qalin ah, iyo dahaadhyo kale oo kala duwan, sida suufka (mararka qaarkood waxaa lagu dhex dahaadhay nooc ka mid ah wakiilka xinjirowga/dhoobo, sida beeswax) iyo polytetrafluoroethylene (PTFE) ayaa laga heli karaa. Alaabta dahaadhka qadiimka ah waxaa ka mid ah suuf, warqad, ama xariir, laakiin kuwani waxay kaliya faa'iido u leeyihiin codsiyada heerkulka hooseeya (ilaa 105 ° C).

Si loo fududeeyo wax soo saarka, qaar ka mid ah siligga magnet heerkul hooseeya ayaa leh dahaar laga saari karo kulaylka alxanka. Tani waxay ka dhigan tahay in isku xirka korantada ee cidhifyada la samayn karo iyada oo aan marka hore la saarin dahaarka.
