Yintoni indibaniselwano yempahla ekrwada izitena ezikhanyelayo kuthetha ntoni?

Ukudityaniswa kwezitena ezichasayo kubhekiselele ekudityanisweni kwezinto zodongwe kunye nezinto ezingezizo ezeplastiki ukwenza amaqoqo odongwe eplastiki kwaye abe namandla athile omileyo. Ukukwazi ukudibanisa udongwe oludibeneyo luhlala lubonakaliswa ngumlinganiselo wesanti yequartz eqhelekileyo (i-70% yi-0.25 ~ 0.15mm, i-30% yi-0.15 ~ 0.09mm) kunye namandla okuguquguquka emva kokumisa xa umzimba wodongwe weplastiki usenziwa. Udongwe oluneplastikhi eyomeleleyo lunamandla okudibanisa.
