Me yasa ingancin MgO yake da mahimmanci a samar da bututun dumama?
Ga masu kera bututun dumama lantarki, foda magnesium (magnesium oxide foda, MgO) shine "zuciya" na bututun dumama lantarki. Ingancin sa kai tsaye yana ƙayyade aminci, aiki, da rayuwar sabis na bututun dumama.
Menene Magnesium foda?
Sunan daidai na "magnesium oxide foda" shine MgO, wani fili na ionic wanda ya ƙunshi magnesium da oxygen. Fari ne, mara wari, da ɗanɗano mai ɗanɗano.
A yawancin aikace-aikacen masana'antu, irin su abubuwan dumama wutar lantarki, abin da muke kira da "magnesium foda" shine ainihin "magnesium oxide foda" (MgO), wani barga, wanda ba {0} abu na yumbu mai ƙonewa, wanda ya bambanta da foda na magnesium mai ƙonewa.
Me yasa yake da mahimmanci don amfani da ingantaccen foda na magnesium oxide mai inganci a cikin abubuwan dumama?
Wannan ya samo asali ne daga ainihin kaddarorin sa guda huɗu, waɗanda kai tsaye ke ƙayyade aiki, aminci, da tsawon rayuwar abubuwan dumama:
1. Kyakkyawan Insulation
Magnesium oxide is an excellent insulator with an extremely high resistivity (>10¹³ Ω·cm a dakin da zafin jiki). Ya dogara da keɓe wayar dumama kuzari mai kuzari (wayar juriya) daga rumbun ƙarfe da ke kewaye, yana hana yaɗuwa ko gajeriyar kewayawa da tabbatar da amincin mai amfani. Wannan shine babban aikin sa.
2. Madalla da Thermal Conductivity
Magnesium oxide's thermal conductivity (kimanin 30{2}}40 W/(m·K)) ya fi na iska. Yana da inganci kuma a ko'ina yana jujjuya babban zafin zafin da wayar dumama ke haifarwa zuwa rumbun karfe, sannan zuwa ga abu mai zafi. Wannan ba wai kawai yana inganta aikin dumama ba har ma yana hana tarin zafi a cikin wayar dumama, wanda zai iya haifar da zafi da zafi a cikin gida da kuma ƙonewa, ta haka zai ƙara tsawon rayuwarsa
3.Sintered magnesium oxide yana da wurin narkewa har zuwa digiri 2800.
Yana da tsayin daka sosai a yanayin yanayin aiki na yau da kullun na abubuwan dumama (daruruwa da yawa zuwa dubunnan digiri Celsius). Baya rubewa, canzawa, ko amsa sinadarai tare da rufaffiyar waya mai dumama ko harsashi na bututun ƙarfe, yana tabbatar da dogaro mai tsawo{1}.
4. Babban Ƙarfin Injini da Ƙarfin Marufi
A lokacin aikin masana'anta na abubuwan dumama, tsarin "tube shrinking" yana faruwa, inda aka matse bututun ƙarfe a ƙarƙashin babban matsin lamba don ƙaddamar da foda na magnesium oxide a ciki. Magnesium oxide foda mai inganci{1} tare da daidaitaccen girman rabo zai iya jure wannan matsa lamba ba tare da takure ba. Bayan ƙaddamarwa, yana samun babban maɗauri mai yawa, yana kawar da ɓoyayyiyar ciki, yana tabbatar da matsakaicin insuli da zafin zafin jiki, da kuma hana lalacewar aiki saboda girgiza.
Dangane da waɗannan kaddarorin, ana amfani da foda na magnesium oxide a cikin:
Abubuwan dumama: Wannan shine yanki mafi girma na aikace-aikacen. Ana amfani dashi a cikin abubuwa masu dumama tubular daban-daban (bututun dumama), dumama dumama, dumama faranti, da sauran aikace-aikace. Ana samun sa a cikin kettles na lantarki, tanda, dumama sararin samaniya, tukunyar jirgi na masana'antu, da ƙari.
A kasuwa, ma'auni/tsakiyar -majin magnesium foda yana ƙunshe da kusan 98% zuwa 99.3% MgO tsafta, yana alfahari da ingantaccen rufi da ɗawainiyar zafi, da kyau{3} sarrafa danshi. Ya cika buƙatun galibin abubuwan dumama wutar lantarki na gabaɗaya{5}, yana mai da shi mashahurin zaɓi don kayan aikin gida na yau da kullun kamar kettle na lantarki, tanda, murhun microwave, injin dafa shinkafa, da na'urar dumama ruwa.
