KUSHANDISA

Tsananguro yeChigadzirwa

Upfu hwe alumina hwakasanganiswa hunoitwa nehupfu hwe alumina hune sodium shoma hwakachena nekunyunguduka pakupisa kwakanyanya, kutonhora crystallization, uye kupwanywa. Hupfu hwe alumina hwakasanganiswa huchena hunodzorwa zvakasimba kuti hurambe hwakapararira uye huchitaridzika zvakafanana.

Kupararira kwehukuru hwetsanga yeupfu hwealumina hwakasanganiswa kushoma. Mushure mekugadzirisa chimiro, upfu hwecorundum chena hwakachena kwazvo hune tsanga yakazara, mipendero yakapinza nemakona, kushanda zvakanaka kwekukuya, uye kupenya kwakanyanya. Kushanda zvakanaka kwekukuya kwakakwira zvakanyanya kupfuura zvinobvisa zvakapfava zvakaita sesilica.
