6. Rufin zafi:Babban porosity yana hana watsa zafi da kuma fitar da shi, wanda hakan ke sanya shi kyakkyawan kayan kariya mai zafi sosai.
7. Matsakaicin ƙarfin injina:Ƙarfin matsewa da ƙarfin lanƙwasa suna cika buƙatun amfani da masana'antu, kuma suna da wani matakin tauri, wanda ba ya yin rauni cikin sauƙi.
8. Ƙarfin gyare-gyare mai ƙarfi:Ana iya keɓance girma dabam-dabam, siffofi da PPI don haka zai iya biyan buƙatun aikace-aikace daban-daban.
- Filin tacewa mai zafi sosai
1. Tacewar narkewar ƙarfe:Lokacin da ake yin amfani da ƙarfe marasa ƙarfe kamar aluminum, jan ƙarfe, zinc, da sauransu, yana tace abubuwan da ke cikin oxide da ƙwayoyin da ba su da tsabta a cikin narkewar don inganta tsarkin simintin.
2. Tacewar iskar gas mai zafi:ana amfani da shi don cire ƙurar hayaki mai yawan zafin jiki a masana'antu kamar su aikin ƙarfe, injiniyan sinadarai, da ƙona shara, da kuma katse ƙurar da kuma tsarkake iskar gas.
- Filin rufewar zafi
1. Rufin murhun masana'antu:rufin rufi don murhun yumbu, murhun ƙarfe, da murhun gilashi don rage asarar zafi da adana kuzari.
2. Abubuwan da ke cikin sararin samaniya:A matsayin kayan kariya ga jiragen sama da injuna, suna iya jure yanayin zafi mai yawa.
- Filin jigilar kaya mai haɓaka catalytic
