Xirmooyinka dhoobada Qaabaysan

Sharaxaad Gaaban:

Xirmooyinka dhoobada qaabaysan ee dhoobada waxay ka kooban tahay qaybo badan oo baakad ah oo nashqad joomatari la mid ah. Go'yaal jiingado ah oo lagu dhejiyay qaab isbarbar socda unugyo cylindrical ah oo loo yaqaan xirxirida munaaradda. Kuwani waa nooc ka mid ah baakad aad u hufan oo leh kala saarid hufnaan dhowr jeer ka sarreeya baakooyinka dabacsan. Waxay leeyihiin tayada hoos u dhaca cadaadiska hooseeya, kororka dabacsanaanta hawlgalka, saamaynta ugu yar ee weynaynta, iyo daaweynta dareeraha ugu badan marka la barbar dhigo xidhidhiyaha munaaradda random.

Alaabooyinka HordhacaBaakad qaabaysan dhoobada

Sababtoo ah qaab dhismeedka gaarka ah ee dhoobada, waxqabadka wanaagsan ee hydrophilic, dusha sare wuxuu samayn karaa filim dareere ah oo aad u khafiif ah oo qulqulaya qulqulka hawada qulqulaya iyo kanaalka tortuous waxay kor u qaadi karaan hawada laakiin ma joojin karaan u dhigma hawada buuxinta birta waxay ka dhigi kartaa xirmooyinka dhoobada, iyo iska caabbinta daxalka, heerkulka sare ee heerkulka u adkaysta ee buuxinta birta lama barbar dhigi karo. Qaab dhismeedka dusha sare wuxuu leeyahay hanti qoynta wanaagsan, wuxuu dardargelin karaa socodka dareeraha, wuxuu ka dhigayaa dib u dhigista mugga dareeraha ugu yaraan. Si loo dhimo fursada kulaylka, isu-ururinta, iyo kulaylinta. Alaabtan waxa ay ka samaysan tahay qalab tayo sare leh oo kiimiko dhoobo ah oo wax lagu farsameeyo oo noqda, adkaysi u leh heerkulka sare iyo cadaadiska sare, xasiloonida kiimikada wanaagsan iyo xoogga sare, waa side ku haboon in lagu taageero noocyada kala duwan ee kicinta.
