Calaamadaha alaabta

Nichrome, oo sidoo kale loo yaqaan chrome nikkel, waa daawaha la soo saaray iyadoo la isku daray nikkel, chromium iyo, marmar, birta. Ugu wanaagsan ee loo yaqaan iska caabinta kulaylka, iyo sidoo kale iska caabbinta daxalka iyo oksaydhka labadaba, daawaha ayaa si aad ah waxtar ugu leh codsiyo badan. Laga soo bilaabo waxsoosaarka warshadaha ilaa shaqada hiwaayadda, nichrome oo ah qaab silig ah ayaa ku jira alaabooyin ganacsi oo kala duwan, farsamooyin iyo qalab. Waxay kaloo ka heshaa codsiyo goobo gaar ah.

Siligga Nichrome waa daawaha laga sameeyay nikkel iyo chromium. Waxay ka hortagtaa kulaylka iyo oksaydhka waxayna u adeegtaa sidii kuleyliyaha alaabada sida toasters -ka iyo qalajiyaha timaha. Dadka hiwaayadda leh waxay u isticmaalaan silig nichrome farshaxanka dhoobada iyo sameynta galaaska. Siligga waxaa kaloo laga heli karaa shaybaarrada, dhismaha iyo qalabka elektiroonigga ee gaarka ah.

Sababtoo ah siligga nichrome ayaa aad u adkaysi u leh korantada, aad bay waxtar ugu leedahay sida kuleyliyaha alaabada ganacsiga iyo aaladaha guriga. Toasters -ka iyo qallajiyeyaasha timaha waxay adeegsadaan xargaha silig nichrome si ay u abuuraan qaddar badan oo kuleyl ah, sida foornooyinka wax lagu dubto iyo kululeeyayaasha kaydinta. Foornooyinka warshadaha ayaa waliba isticmaala silig nichrome si ay u shaqeeyaan. Dhererka siligga nichrome ayaa sidoo kale loo isticmaali karaa in lagu abuuro gooyo silig kulul, kaas oo loo adeegsan karo guriga ama goob warshadeed si loo gooyo loona qaabeeyo xumbo iyo caagag gaar ah.

Siligga Nichrome wuxuu ka samaysan yahay daawaha aan magnetka ahayn oo ka kooban nikkel, chromium, iyo bir. Nichrome waxaa lagu gartaa iska caabbinta sare iyo iska -caabbinta oksaydhka ee wanaagsan. Siligga Nichrome sidoo kale wuxuu leeyahay ductility wanaagsan ka dib isticmaalka iyo weldability aad u fiican.

Lambarka soo socda kadib nooca siligga Nichrome wuxuu muujinayaa boqolleyda nikkel ee ku jirta daawaha. Tusaale ahaan, "Nichrome 60" wuxuu ka kooban yahay qiyaas ahaan 60% nikkel.

Codsiyada siligga Nichrome waxaa ka mid ah walxaha kululaynta timo qalajiyaha, kuleyliyeyaasha kululaynta, iyo taageerada dhoobada ee kilyaha.
