Habka wax soo saarka ee Kubadaha dhoobada ah ee Aluminium Oxide

Xulashada Qalabka Ceyriinka:

Budada oksaydhka aluminium ee nadiifka ah ee nadiifka ah ayaa loo doortaa sida alaabta ceeriin ee aasaasiga ah. Iyada oo ku xidhan codsiga, nadiifnimadu waxay u dhaxaysaa 90% ilaa 99.7% ama ka sareeya.

Isku darka:

Budada oksaydhka aluminiumku waxa lagu daraa waxyaabo lagu daro sida kuwa isku xidha (tusaale ahaan, polymers organic) iyo balaastikada si loo hagaajiyo shaqada loona hubiyo in isku dhafka loo qaabayn karo goobo.

Abuurista:

Isku darka ayaa markaa loo sameeyay qaabab wareegsan iyadoo la adeegsanayo mid ka mid ah habab dhowr ah:

Bixinta: Waa hab isku dhaf ah lagu rido durbaan wareeg ah oo biyo lagu daray si tartiib tartiib ah si ay u sameeyaan qaybo wareegsan.

Bixinta iyo GoyntaIsku darka waxaa laga soo saaraa dhillo waxaana la googooyaa qaybo yaryar oo markaa la wareegsan.

Cirbadaha mudistaXaaladaha qaarkood, isku dar ah ayaa lagu duri karaa si toos ah qaabka goobeed.

Qallajinta:

Marka la sameeyo, jidhka cagaarka ah (qaababka dhoobada aan la shidin) waxay u baahan yihiin in la qalajiyo si looga saaro qoyaanka hadhaaga ah. Tan waxa lagu samayn karaa iyada oo la isticmaalayo hawo qalajinta, microwave-ka lagu qalajiyo, ama foornooyinka caadiga ah.
