Tšebeliso ea zeolite e le ho tlatsa indasteri ea pampiri e ka ntlafatsa ts'ebetso le boleng ba pampiri, e le hore porosity ea eona e eketsehe, ho kenngoa ha metsi ho matlafatsoe, ho bonolo ho khaola, ho ngola tshebetso ho ntlafatsoa, 'me ho na le ho hanyetsa ho itseng ha mollo.

Indasteri ea polasetiki

Indasteri ea polasetiki bakeng sa tlhahiso ea polyvinyl chloride, polasetiki ea amino, polasetiki ea urea formaldehyde, likopi tsa pente joalo-joalo.

Indasteri ea Photovoltaic

Oxalic acid e boetse e sebelisoa indastering ea photovoltaic.Oxalic acid e ka sebelisoa ho etsa li-wafers tsa silicon bakeng sa liphanele tsa letsatsi, ho thusa ho fokotsa likoli holim'a liphaphatha tsa silicon.

Ho hlatsoa lehlabathe

Oxalic acid e kopantsoe le hydrochloric acid le hydrofluoric acid e ka sebetsa ho hlatsuoa ha acid ea lehlabathe la quartz.
