Zvinoenderana neakasiyana maitiro, anogona kukamurwa kuita mapoka maviri: solidified sefa bepa uye isina kupora sefa pepa.Pepa resefa rakapora rinowanzo kuisirwa nephenolic resin, uye rozobikwa patembiricha ye150-180 madhigirii kwemaminetsi gumi nemashanu kurapa resin uye kuwedzera kupinza kwepepa resefa.Pano "cured filter paper" yakabuda!
"Cured filter paper" inobatwa nekupisa kwepamusoro, uye mapepa emapuranga anenge akavharwa zvachose neresin."Pepa risingarapiswe resefa" rinowanzoshandisa polyvinyl acetate resin semumiriri, uye inopedzwa nekudonha zvakangoita mushure mekuiswa.Nokudaro, kuoma uye kuoma kwepepa resefa hazvina kunaka se "cured filter paper".Uyezve, "non-cured filter paper" iri nyore kutora mvura uye kuva yakanyorova, uye panguva imwecheteyo, kupikisa kwayo kwekushisa kwakanyanya hakuna kufanana ne "bepa rakapora".Zvishandiso zveaya marudzi maviri emasefa mapepa akafanana, asi iyo inotevera impregnation maitiro akasiyana zvachose!——” Pepa resefa rakapora” zviri pachena kuti riri nani, haripindi mvura, risingapindi acid, rinodzivirira kutonhora kwakadzika, rinodzivirira kutonhora kwepamusoro, uye rinodzivirira alkali.
Pawelson® mhepo sefa inoshandisa Ahlstrom sefa bepa, uye bepa resefa rakaporeswa pakupisa kwakanyanya, zvisinei kuti injini yako iri kutarisana nenzvimbo dzakaomarara, inogara ichiona kuti injini yako ine basa repamusoro.
