Dhuumaha Cadaadiska Sare ee aan Xumaan lahayn, Hababka wax soo saarka
Dhuumaha cadaadiska sare, waa nooc ka mid ah tuubo aan tol lahayn.Habka wax-soo-saarka ayaa la mid ah sida dhuumaha aan xuduudda lahayn, laakiin waxaa jira shuruudo adag oo ku saabsan nooca birta loo isticmaalo soo saarista tuubooyinka birta.Sida laga soo xigtay isticmaalka heerkulka waxaa loo qaybiyaa laba nooc oo ah tuubada kululeeyaha guud iyo tuubada kululeeyaha-cadaadiska sare.
① Cadaadiska sare ee tuubooyinka aan fiicnayn, Marka heerkulka hawlgalka uu ka hooseeyo 450 ℃, tuubada guriga waxaa inta badan laga sameeyaa no.10 iyo No.20 carbon bonded birta kulul duuban ama tuubo qabow barbaro.
② Cadaadiska sare ee tuubo aan xuduud lahayn, Marka la isticmaalo, tuubada inta badan waxay ku hoos jirtaa heerkul sare iyo cadaadis sare.Marka la eego ficilka heerkulka sare ee gaasta qiiqa iyo uumiga biyaha, oksaydhka iyo daxalka ayaa dhici doona.Dhuumaha birta ayaa looga baahan yahay inay lahaadaan xoog waara oo sarreeya, caabbinta daxalka oksaydhka sare iyo xasilloonida qaab-dhismeedka yar yar ee wanaagsan.
