Xaashiyaha birta duuban ee qaboobaha ( xaashida birta CR) asal ahaan waa bir duuban oo kulul oo si dheeraad ah looga shaqeeyay
Saxan bir ah oo 'duuban' ah ayaa badanaa loo adeegsadaa si loo qeexo habab kala duwan oo loo dhammeeyo-inkastoo, farsamo ahaan, 'qabow duuban' ay khusayso oo keliya xaashida isku xidhka rolalka dhexdooda.Waxyaabaha sida baararka ama tuubooyinka waa 'la sawiray,' lama duubin.Hababka kale ee dhamaystirka qabowga waxaa ka mid ah rogid, shiidi iyo turxaan-mid kasta oo ka mid ah waxaa loo isticmaalaa in lagu beddelo kaydka kulul ee hadda jira oo loo beddelo badeecooyin la safeeyey.
Gariiradda birta duuban ee qabow ee ST12 waxaa badanaa lagu aqoonsan karaa sifooyinka soo socda
1.Cold birta duuban ayaa si ka sii fiican, dusha sare u dhammaatay oo leh dulqaad u dhow
2.Sagxadaha siman ee inta badan saliidda leh ee taabashada xaashida birta CR
3. Baararka waa run iyo labajibbaaran, waxayna badanaa leeyihiin geeso iyo geeso si fiican loo qeexay
4.Tubes waxay leeyihiin lebbis gaar ah oo qumman iyo toosnaan, oo laga sameeyay walxo qabow oo duuban.
5.Cold gariiradda birta duuban oo leh sifooyin dusha sare ka wanaagsan birta kulul, ma aha wax la yaab leh in birta duuban qabow waxaa inta badan loo isticmaalo codsiyada dheeraad ah oo farsamo sax ah ama meesha bilicsanaanta waa muhiim.Laakiin, iyada oo ay ugu wacan tahay habaynta dheeraadka ah ee alaabta qabow ee dhammaatay, waxay ku yimaadaan qiimo sare.
Marka la eego sifooyinkooda jireed, biraha qabowga lagu shaqeeyo ayaa caadi ahaan ka adag oo ka xoog badan biraha duuban ee caadiga ah.Tani waa sababta oo ah dhamaystirka birta duuban ee qabow waxay abuurtaa badeeco adag.Waxaa xusid mudan in daawayntan dheeraadka ah ay sidoo kale abuuri karaan culaysyo gudaha ah oo ku jira maaddada.Si kale haddii loo dhigo, marka la samaynayo birta qabow ka shaqeysa - haddii ay goynayso, shiiddo ama alxanayso - tani waxay sii deyn kartaa xiisadaha waxayna horseedi kartaa dagaal aan la saadaalin karin.
