Tuubooyinka Birta ee Cinjirka ah
Tuubooyinka birta ah ee caagga ah waxaa loogu talagalay in loo isticmaalo codsiyada kala duwan ee bamgareynta. Codsiyada sida daadinta warshadda, bambooyinka cadaadiska sare, khadadka dabada dheer, codsiyada bamka slurry-ka ee adag iyo tuubooyinka cufisjiidadka. Dhammaad kasta waxaa ku jira shaabad caag ah oo dabacsan.
Tuubada birta ah ee caagga ah ee u adkaysta xirashada iyo daxalka waxay ka samaysan tahay tuubo bir ah oo caadi ah oo ah walxo qaab-dhismeed waxaana loo isticmaalaa sifooyin aad u fiican oo ah caag u adkaysta xirashada, u adkaysta daxalka iyo caag u adkaysta kulaylka sida lakabka dahaarka. Waxaa isku daray tignoolajiyad gaar ah oo leh dhejis waxqabad sare leh. Inta badan waxaa loo isticmaalaa birta, korontada, warshadaha kiimikada, batroolka, dhuxusha, sibidhka iyo qaybaha kale ee warshadaha. Shaqada macdanta, waxaa si weyn loogu isticmaalaa nidaamka gudbinta dabada macdanta, buuxinta macdanta dhuxusha iyo goobaha nidaamka tuubooyinka la xiriira. Gaar ahaan, dhuumaha ayaa aad ugu habboon gudbinta heerkulka u dhexeeya -50°C ilaa +150°C dhexdhexaad ah, kaas oo si fudud loo xidhi karo oo daxalaysan. Waxaan kordhin karnaa dhumucda derbiga geeska tuubada iyadoo loo eegayo baahida macaamiisha, sidaas darteedna loo dheereynayo cimriga adeegga. Dhanka kale, cimriga adeegga ee tuubada birta ah ee caagga ah waxay gaari kartaa 15-40 sano guud ahaan. Tuubada waxaa lagu wareejin karaa ku dhawaad 90 digrii ka dib 6-8 sano oo adeeg ah. Waqti kasta oo wareeg ah ayaa kordhin kara cimriga adeegga. Tuubada birta ah waxaa si isdaba joog ah loogu dahaadhi karaa caag saddex ilaa afar jeer, taasoo yareyneysa isticmaalka kharashaadka.
