kan-thal D silig daawaha fecral

Siliga Kanthal waa bir-chromium-aluminium (FeCrAl) daawaha. Si sahal ah uma daxalaystaan ​​ama oksidhis uguma samaynayso codsiyada warshadaha waxayna leedahay iska caabin aad u fiican oo ay u leedahay walxaha daxalka ah.

Siliga Kanthal wuxuu leeyahay heerkulka ugu sarreeya ee hawlgalka marka loo eego siliga Nichrome. Marka la barbardhigo Nichrome, waxay leedahay culeys sare oo dusha sare ah, iska caabin sare, xoog wax soo saar sare, iyo cufnaanta hoose. Siliga Kanthal wuxuu sidoo kale ku jiraa 2 ilaa 4 jeer in ka badan siliga Nichrome sababtoo ah sifooyinka oksaydhka ee sarreeya iyo caabbinta jawiyada sulfuric.

Kanthal Dwaxaa loogu talagalay in lagu isticmaalo heerkul ilaa 1300°C (2370°F).

Noocaan silig Kanthal ah uma adkeysan karo daxalka sulfuric sidoo kaleKanthal A1. Siliga Kanthal D waxaa inta badan laga helaa qalabka guriga sida weelka dhaqda, ceramics ee kululeeyayaasha, iyo kuwa dharka lagu dhaqo. Waxa kale oo laga heli karaa codsiyada warshadaha, badanaaba walxaha kululaynta foornada.Kanthal A1waxaa inta badan loo doortaa codsiyada foornada warshadaha ee waaweyn sababtoo ah iska caabinteeda sare, iska caabbinta daxalka qoyan ee wanaagsan, iyo kuleylka sare iyo xoogga gurguurta. Mid ka mid ah faa'iidooyinka ugu muhiimsan ee Kanthal A1 ee Kanthal D waa xaqiiqda ah in aysan si fudud u oksijiin.

Iyada oo ku xidhan iska caabbinta loo baahan yahay, heerkulka hawlgalka ugu badan, iyo dabeecadda daxalaysa ee curiyaha, waxa laga yaabaa inaad rabto inaad doorato siligga Kanthal A-1 ama Kanthal D.
