Brass pob li qub, raws li ib hom kev tswj cov kua dej valve, ib txwm cheem loj heev ntawm lawv cov tseem ceeb tivthaiv - lub pob. Yog li, dab tsi yog cov khoom ntawm lub pob nyob rau hauv ib tug tooj dag pob valve? Cov lus teb yog tooj dag. Brass yog feem ntau tsim los ntawm tooj liab, feem ntau muaj 60% rau 90% tooj liab, nrog rau cov khoom siv uas tsim nyog los txhim kho nws cov khoom siv thiab corrosion tsis kam.
Tooj dag muaj peev xwm ua tau corrosion zoo tshaj plaws, muaj lub zog siab, muaj zog zoo, thiab zoo heev machinity. Cov yam ntxwv no ua rau tooj cov khoom siv zoo rau kev tsim cov khoom lag luam li qub. Tsis tas li ntawd, tooj dag tau zoo heev thermal conductivity, tso cai rau kev hloov pauv kub sai thiab ua kom lub valve txuas ntxiv mus ua haujlwm ib txwm muaj nyob hauv ib puag ncig.
