Yadda za a zaɓi rufin bulo mai jujjuyawa don sassa daban-daban na tanderun fashewa

Tanderun fashewa yanzu shine babban kayan aikin narkewa. Yana da halaye na sauƙin jin daɗin jama’a da babban ƙarfin samarwa. Rubutun tubali mai jujjuyawa yana taka rawar da ba za a iya sharewa ba a cikin tanderun fashewa, amma rufin bulo na bangon tanderun yana shafar abubuwa da yawa yayin aikin samarwa. Sannu a hankali sai ya lalace. Sabili da haka, don tsawaita rayuwar sabis na tanderun fashewa, ya wajaba don siyan shingen tubali mai jujjuyawa da kyau. Hanyar zabar rufin bulo mai jujjuyawa ga kowane bangare shine:

(1) Murna makogwaro. Yawanci suna ɗaukar tasiri da gogewar cajin ɗan adam, galibi ana amfani da tubalin ƙarfe ko tubalin ƙarfe mai sanyaya ruwa.

(2) Bangaren sama na tanderun. Wannan bangare shi ne yankin da yanayin juyin halittar carbon 2CO2-CO + C ke da yuwuwar faruwa, kuma zazzagewar karafa na alkali da tururin zinc shima yana faruwa a wannan yanki.
