Izibonelelo zohlobo lwefrifiti yodidi yesalfure ngaphezulu kwendlu yesilika yesalfera, ispreyi luhlobo lwesalfure kunye neglasi yokugxininisa ukufakelwa kwiplasitiki kubonakaliswa ikakhulu kwezi zinto zilandelayo:
1. Uhlobo olulula lokutshiza lulula ukusebenzisa, kwaye luveliso lwesalfure. Ukuxinwa kwe-acid kuzinzile, okunciphisa ivumba le-so2 kunye nokunciphisa ungcoliseko lwendalo.
2. Inqaba yesitshiza yohlobo lokutshiza kulula ukuyilungisa nokuyigcina. Ukuba isiphumo sihle, akukho sondlo phantse unyaka. Akukho fayibha yeglasi eyomeleziweyo fan yeplastiki okanye fan yeceramic.
3. Inqaba yesalfera yohlobo lokutshiza inokubakho kakuhle kwe-SO2. Izinga lokufakwa kwe-SO2 ngokubanzi lingaphezulu kwama-95%. Izinga lokufunxa kwezinye iitawuli zesalfure lihlala lijikeleze ama-75%, eligcina iindleko ezininzi zesulfure ngonyaka omnye.
