Tuubooyinka birta ah
Toobabka birta caagga ah ee birta ah waxaa loogu talagalay in loo isticmaalo codsiyo bam-gacmeed oo kala duwan. Codsiyada sida Mill Dheecaan, bambooyin cadaadis sare, xariiqyo dhaadheer, oo dalbanaya codsiyada bamka sturry iyo tuubooyinka culeyska. Dhamaad kasta oo uu ku dhamaaday xargaha caagga caagga ah ee firidhsan.
Xijaab u adkaysata oo jilicsan oo bir ah oo jilicsan oo bir ah oo bir ah Waxaa isku dhafan tikniyoolajiyad gaar ah oo ay ku dhajisay wax qabad aad u sarreysa. Badanaa loo isticmaalay metalrulgy, korantada, warshadaha kiimikada, batroolka, dhuxusha, sibidhka iyo aagagga kale ee warshadaha kale. Shaqada macdanta, waxaa si weyn loogu isticmaalaa nidaamka codadka codadka miinada, miinada dhuxusha iyo kuwa la xiriira tuubadaha laxiriira. Gaar ahaan, dhuumaha ayaa aad ugu habboon in loo gudbiyo heerkulka u dhexeeya -50 ° C illaa + 150 ° C dhexdhexaadinta, taas oo fududahay in la xidho oo la xidho. Waxaan ku kordhin karnaa dhumucda darbiga ee geedka tuubbada iyadoo loo eegayo baahida macaamiisha, sidaa darteed kordhinta nolosha adeegga. Dhanka kale, nolosha adeegga ee tuubbada birta birta-saqafka leh ee lagu xiro ayaa gaari kara 15-40 sano guud ahaan. Tuubbada waxaa la wareegi karaa ku dhawaad 90 digrii kadib 6-8 sano oo adeegga ah. Waqti kasta oo wareejin ah ayaa kordhin kara nolosha adeegidda, tuubada birta waxaa lagu soo rogi karaa caag ah saddex ilaa afar jeer, sidaas darteedna waxay yareynaysaa isticmaalka kharashyada dheer.
