Ku hlanganisiwa ka yona ka ku tiya ka 260°C, ku nga tirhi ka tikhemikhali, vuandlalo lebyi nga namarheliki, na ku tiya ka dimensional swi endla leswaku yi va ya nkoka swinene eka ti baghouse dust collectors, ti liquid filter cloths, na ti high-efficiency air filters.
Aokai PTFE yi phakela lapi ra PTFE eka switirhisiwa swa filtration emisaveni hinkwayo. Xihloko lexi xi katsa swiyenge swa ntlhanu leswikulu: ku susiwa ka ntshuri wa gasi ya xigwitsirisi hi mahiselo yale henhla, ku sefa mati lama onhaka, ku sefa ka swakudya/mirhi leswi nga riki na switsongwatsongwana, ku sefa moya wa le kamareni ro basa, na ku sefa ka melt hi ndlela yo hlawuleka.

In summary , PTFE lapi ra mahiselo yale henhla i xitshunxo xa premium eka swiyimo swo tirha swa filtration yo tlula mpimo. Yi yime tani hi xitirhisiwa xo sefa lexi tsakeriwaka kumbe lexi nga lavekiki eka swiyimo leswi katsaka mahiselo yale henhla (kufika eka 260°C kuya emahlweni), acid-alkali corrosion yo tiya, na ntshuri wo namarhela. Ngopfu ngopfu ayi cinciwi eka ku susiwa ka ntshuri wa baghouse ya mahiselo yale henhla (cement, ku hisiwa ka thyaka, ti coal boilers) xikan’we naku hambanisiwa ka solid-liquid leyi onhaka.
Eka swiyimo leswinga laviki ngopfu, switirhisiwa swa ntsengo wale hansi swofana na polyester, PPS, kumbe aramid swinga ringanerile. Kambe loko mbango wu susumeta swipimelo – 260°C, acid dew point, kumbe ti sticky particulates – PTFE-coated fiberglass fabric yi tisa matirhelo yo tshembheka, lawa ya tshamaka nkarhi woleha.
