Munguva iyo kunyatsorurama, kugara kwenguva refu, uye kushanda zvakanaka zvinotsanangura kufambira mberi kwemaindasitiri,waya ye nichromeinoramba iri chinhu chikuru mukuvandudzwa kwekupisa. Yakagadzirwa zvakanyanya ne nickel (55–78%) uye chromium (15–23%), ine huwandu hushoma hwesimbi nemanganese, hunhu hwakasiyana hwe alloy iyi hunoita kuti ive yakakosha mumaindasitiri - kubva kumidziyo yemumba kusvika kumainjiniya emuchadenga. Pano, tinoongorora mashandisirwo akasiyana-siyana e nichrome wire uye basa rayo mukugadzira matekinoroji emazuva ano ekupisa.

 

Zvimiro Zvikuru Zvinotungamira Kuchinja-chinja kweNichrome

Kukosha kweNichrome kuri mukuenzana kwayo kwakasiyana-siyana kwehunhu hwemuviri nehwemagetsi. Nekusimba kwayo kwe1.0–1.1×10⁻⁶ Ω·m uye nzvimbo yekunyunguduka inodarika 1400°C315, inoshandura simba remagetsi kuita kupisa zvinobudirira uku ichiramba oxidation uye ngura kunyangwe mumamiriro ezvinhu akaoma. Hunhu hwayo husina magineti, ductility, uye kuwedzera kwekupisa kushoma zvinowedzera kuchinjika kwayo315. Hunhu uhwu hunovimbisa kushanda kwakasimba munzvimbo dzinoda kuvimbika, kubva kumaovheni eindasitiri ane tembiricha yepamusoro kusvika kumidziyo yekurapa chaiyo.

 

Mashandisirwo Akakosha eNichrome Wire

1. Midziyo yemumba

Waya yeNichrome ndiyo musimboti wezvishandiso zvezuva nezuva zvekudziisa. Matosta, mahair dryer, maovheni, nemakettle emagetsi zvinotsamira pakukwanisa kwayo kugadzira kupisa kwakafanana nekukurumidza. Semuenzaniso,nichrome 60inoshandiswa zvakanyanya mumidziyo inopisa zvine mwero senge magrill nemaheater ekuchengetera, nepo nichrome 80 (Ni80Cr20) inobudirira mukushandiswa kwakasimba senge maheater emvura nemaironi ekusonesa nekuda kwekunamatira kwayo kwakanyanya kwe oxide uye kugara kwenguva refu915.

2. Maitiro Emaindasitiri Nekugadzira

Munzvimbo dzemaindasitiri, waya ye nichrome inosimbisa maovheni emagetsi, makiln, uye michina yekugadzirisa kupisa. Kusagadzikana kwayo - kuchengetedza hunhu hwayo pasi pekumanikidzwa kwenguva refu patembiricha iri pamusoro pe400°C - kunoita kuti ive yakakodzera kunyungudutsa, kunyungudutsa, uye kurapwa nekupisa315. Maindasitiri akaita sesimbi neceramics anoshandisa nichrome strips uye coils kuti dzigadzikane mukuderedza mhepo, kudzivirira matambudziko akaita se "green rot" anowanikwa mune mamwe ma alloys9.

 

3. Masisitimu eNdege neMotokari

Kuvimbika kweNichrome kunosvika kunzvimbo dzinoda simba dzakadai semasystem ekubvisa icing mumhepo, ma sensor einjini, uye maheater emumba. Kugona kwayo kutsungirira kupisa uye mamiriro akaoma kunoita kuti zvinhu zvakakosha zvive zvakachengeteka uye zvinoshanda zvakanaka. Mashandisirwo emotokari anosanganisira mawasher echigaro uye tambo dzinonyungudutsa, uko nichrome 30 ne40 dzakasiyana dzinopa kupisa kwakasimba uye kusingadyi simba zvakanyanya9.

4. Midziyo yekurapa neyemurabhoritari

Mukurapa, waya ye nichrome inogonesa kudzora kupisa kwakanyatsojeka mumidziyo yekuvhiya, ma heating pads, uye michina yekuuraya utachiona. Marabhoritari anoshandisa kusashanda kwayo pakuedza murazvo uye kubatidza mishonga inorwisa utachiona iri kure, zvichideredza njodzi dzekusvibiswa715.

5. Zvitsva Zviri Kubuda Uye Mhinduro Dzakagadzirwa Nevatengi

Kufambira mberi mu nichrome alloys kunotarisa pakuvandudza kushanda zvakanaka kuburikidza nekugadzirwa kwakanatswa uye matekiniki ekugadzira. Semuenzaniso, kunyungudutsa kwe vacuum-induction, kunogadzira mamakisi akaita seNi80Cr20-VI, akagadzirirwa michina yemagetsi inodziya zvakanyanya3. Pamusoro pezvo, basa re nichrome mumidziyo inoshandisa simba shoma uye machira ekupisa anopfapfaidza anoratidza kugona kwayo mumabasa emaindasitiri anochengetedza nguva dzose15.

 

Kusarudza Waya Yakakodzera yeNichrome

Kusarudza giredhi rakakodzera uye geji kunoda kuongorora tembiricha yekushanda, mamiriro ekunze, uye zvinodiwa nemagetsi. Waya dzakatetepa (geji yepamusoro) dzinoenderana nezvinodiwa zvakanyanya, nepo mhando dzakakora dzichibata mutoro wemagetsi wakakura15. Kune nharaunda dzakanyanya, nichrome 70 ne80 dzinopa kugara kwenguva refu kusingaenzaniswi, nepo nichrome 20 ichienzanisa mutengo uye mashandiro emagetsi emagetsi9.

 

Kufunga Nezvekuchengetedza uye Kuchengetedza Nguva

Kunyange hazvo kusapisa kwe nichrome kuchideredza zvinodiwa pakugadzirisa, kubata kwakakodzera kuchiri kukosha. Kudzivirira kupisa, kudzora tembiricha, uye kuongororwa nguva dzose zvinoderedza njodzi dzekupisa zvakanyanya uye njodzi dzemagetsi15. Uyezve, kugara kwayo kwenguva refu uye kugona kwayo kudzokororwa zvinoenderana nekuedza kwenyika dzese kuderedza marara emaindasitiri.

Semutungamiri mukugadzirisa ma alloy epamusoro, tinonyanya kugadzira waya dze nichrome dzinoshanda zvakanaka dzakagadzirirwa mashandisirwo akasiyana-siyana. Zvivako zvedu zvemazuva ano zvinoshandisa mainjiniya ekugadzira nemazvo uye kutonga kwakasimba kwemhando kuti zvipe ma alloy anopfuura mwero weindasitiri. Kubva kuzvinhu zvinodziya zvemhando yendege kusvika kumagadzirirwo e resistor akagadzirwa, zvigadzirwa zvedu zvinosimudzira hunyanzvi muzvikamu zvakasiyana.

Kugona kushandiswa kweNichrome wire kwakasimba zvikuru kunosimbisa chinzvimbo chayo sechinhu chakakosha muinjiniya yemazuva ano. Sezvo maindasitiri achichinja, mashandisirwo ayo achawedzerawo—zvichikurudzirwa nekufambira mberi mune zvesainzi yezvinhu uye kuzvipira kukuchengetedza nguva. Kuti uwane mhinduro dzeNichrome dzakagadzirirwa iwe dzinosangana nezvinodiwa zvako zvehunyanzvi uye zvekushanda, taura nechikwata chedu nhasi.
