1. Kodi zinthu za kampani yathu zimagwiritsidwa ntchito m'mafakitale ati?

Malo ophikira simenti, ma boiler oyaka malasha, kutentha zinyalala, titanium dioxide, chitsulo, zitsulo zosapanga chitsulo, malo opangira magetsi, mafakitale a ceramic, mafakitale a matabwa, mafakitale agalasi, mafakitale a calcium, ndi zina zotero.

2. Kodi kutentha kwa zinthuzo ndi kotani?

Kutentha kwabwinobwino kwa nthawi yayitali ndi koyenera madigiri ochepera 130, kutentha kwapakati ndi koyenera madigiri 150-180, ndipo kutentha kwakukulu ndi koyenera kutentha kwa nthawi yayitali kwa madigiri 180-250.

3. Kodi ubwino wa zinthu zosefera za fiber membrane ya galasi ndi wotani?

Kukana dzimbiri; kukana kutentha kwambiri; kukana okosijeni; kukana hydrolysis; kukana madzi ndi mafuta; mphamvu yayikulu; kukhazikika kwa mawonekedwe; zotsatira zazikulu zochotsa fumbi; magwiridwe antchito okwera mtengo; moyo wautali wautumiki.

4. Kodi pali njira zingati zochizira nsalu yosefera yagalasi?

Chithandizo chanthawi zonse: Ndi kuyika nsalu yosalala yolukidwa pambuyo poiika mu PTFE emulsion ndikuiumitsa. Chithandizo cha N cholimbana ndi asidi: Ndi kuchita chithandizo cholimba cha asidi ndikuyika nsalu yosalala yolukidwa pambuyo poiika mu PTFE emulsion ndikuiumitsa. Chithandizo cha F chophimba filimu: Ndi kuyika filimu ya PTFE pamwamba pa nsalu yokonzedwa.

5. Zinthu zomwe zimakhudza magwiridwe antchito a ulusi wagalasi?

Kapangidwe ka ulusi wagalasi: Zomwe zili mu zigawo monga silicon dioxide, aluminiyamu oxide, alkali metal oxides, ndi zina zotero, zimakhudza mwachindunji zizindikiro zakuthupi ndi zamankhwala monga kukana kutentha ndi kukana dzimbiri kwa ulusi wagalasi;
M'mimba mwake mwa ulusi wagalasi: Monga momwe zimadziwikira, ulusi umodzi wagalasi ukakhala wochepa, umakhala wolimba kwambiri. Tatsimikiza kudzera mu zoyeserera kuti kukana kupindika kwa ulusi wagalasi wa 5μm ndikokwera nthawi 2.5 kuposa ulusi wagalasi wa 9μm, ndipo kukana kupindika kwa ulusi wagalasi wa 3.8μm ndikokwera nthawi 5 kuposa kwa polyester.
