Izinto ezichaphazela ukhuseleko lokufudumeza 8011 I-Alloy Aluminium ye-Alloum ye-Fielda yokubhaka
Intshayelelo: Kutheni uKhuseleko lokufudumeza lube ngumba osembindini weZixhobo zokuPakisha uKutya zale mihla
Njengoko iindlela zokuphila zehlabathi ziguquka, indlela abantu abashushu ngayo, bhaka, pheka, kwaye ukutya okusevenkileni kusenza inguqu enzulu. Nokuba kusezikhitshini zasemakhaya ezineziqhoyi zomoya kunye nee-oveni ezisebenza ngezinto ezininzi okanye kwiindawo zorhwebo ezisebenza ngeenkqubo zokuhambisa umthamo omkhulu., Isidingo semathiriyeli enokumelana ngokukhuselekileyo namaqondo obushushu aphakamileyo sikhule kakhulu. Phakathi kwezi zixhobo, ukutya-ibakala 8011 ifoyile yealuminiyam iphepha lokubhaka ibe sesinye sezisombululo ezisetyenziswa kakhulu ngenxa yebhalansi yayo eyahlukileyo yamandla omatshini, ukuzinza komphezulu, conductivity thermal, kunye nokuhambelana neendawo ezahlukeneyo zonxibelelwano lokutya.
Nangona kunjalo ukufudumeza ukutya kude nenkqubo elula. Imele i-intersection eyinkimbinkimbi yobushushu, ukufuma, ph, umxholo wamafutha, iipateni zokuhamba komoya, kunye nokuzinza kwezinto. Ezi ziguquguqukayo zinempembelelo kwizinto ezithile ezikhuselekileyo zokhuseleko ezifana:
- Ukufuduka kwe-aluminiyam ion,
- ukuthotywa kwe-thermal yeengubo,
- ukungaphumeleli kwesakhiwo ngexesha lokwandiswa kwe-thermal,
- iingozi ezinokutsha xa udibana namafutha,
- ukukhululwa kweekhemikhali kwi-adhesives okanye kwi-composite layers,
- ukulahlekelwa kwentembeko yomatshini ngexesha lokufudumeza ixesha elide.
Ngeenkqubo zolawulo eziqiniswayo kwihlabathi-ezifana ne-EU Framework Regulation (I-ec) Hayi. 1935/2004, I-FDA 21 Cfr, China GB 4806 uthotho, kunye noMthetho woGutyulo wokuTya waseJapan-abavelisi kufuneka baqonde iindlela ezichanekileyo zesayensi ezigqiba ukuba ingaba into isebenza ngokukhuselekileyo phantsi kweemeko zokufudumeza okuqhelekileyo kunye nezigqithisileyo..
Eli nqaku libanzi lidibanisa ulwazi oluvela kwi-metallurgy, ubunjineli be-thermal, chemistry yokutya, isayensi yepolymer, uyilo lwemathiriyeli edibeneyo, kunye nokulungiswa kwamashishini. Injongo yayo kukubonelela ngereferensi ethembekileyo nenzulu yohlalutyo kubavelisi, izixhobo zokuguqula, abalungisi bokutya, iinjineli zokupakisha, kunye namaqumrhu olawulo.
Icandelo I-Metallurgical Foundations of 8011 I-alloy kunye nobudlelwane babo noKhuseleko lokufudumeza
1. Ukwakhiwa kweekhemikhali: Isiseko sozinzo phantsi kobushushu
8011 i-alloy yinxalenye yosapho lwe-Al-Fe-Si kwaye ibandakanya:
