Lebenka dhoobada ah ee Alumina oo leh jeexdin
Astaamaha ugu Muhiimsan
1) Xidhmo wanaagsan: lakabka dhoobada ee alumina dhoobada ah ee chemshun ee ku jira tuubada dhoobada ee u adkaysta xirashada tuubada xusulka ee la dahaadhay waa xoqid Dhoobada, oo leh adkaansho (HRA) ≥84, iska caabbinta xirashada 10 jeer ka badan qalabka tuubada birta ah ee birta ah ee chromium-ka sare leh.
2) Iska caabbinta daxalka: walxo dhoobo ah oo u adkaysta xirashada oo leh iska caabbinta daxalka oo aad u fiican, aashito, alkali, cusbo iyo sifooyin daxalka cusbada halogen.
3) Waxqabadka heerkulka sare: dhoobada u adkeysata xirashada lafteedu waxay leedahay awood heerkul ka badan 1200 darajo Celsius.
4) Yaree kharashka mashruuca: inta badan waxaa loo isticmaalaa gudbinta walxaha, walxaha dareeraha iyo warbaahinta daxalka. beddelka birta aan miridhku lahayn ee qaali ah, tuubo bir ah oo chrome ah oo tayo sare leh, tuubo bir ah oo u adkaysta xirashada, taas oo si toos ah u yareyn karta kharashyada mashruuca dhuumaha.
Hanti aad u fiican oo ilaalinaysa xoqidda iyo xirashada
1) Marka la barbar dhigo tuubooyinka isku dhafan, lakabka foornada ee tuubooyinka dhoobada ah ee chemshun ayaa kharash badan ku baxaya kharashka iibsiga
2) Si fudud loogu rakibi karo qalabka
3) Si fudud ayaa loo hagaajin karaa marka gabal kasta oo dhoobada ah uu waxyeello soo gaaro
4) Cabbir kasta si xor ah ayaa loo isku dari karaa marka la barbar dhigo tuubo isku dhafan
