Tanthauzo la osakanikika

Zinthu zosasunthika zotsalira: Zinthu zosasanjika zosakanizidwa ndizosakanikirana ndi zotsekemera, ufa, binder kapena zowonjezera zina pamlingo wina, ndipo zitha kugwiritsidwa ntchito molunjika kapena kusakanizidwa ndi zakumwa zoyenera. Mwanjira ina, wotsutsa ndi mtundu watsopano wa wotsutsa popanda kuwerengetsa, ndipo mawonekedwe ake osachepera 1580 ° C.

Ufa: amatchedwanso ufa wosalala, amatanthauza imodzi mwa magawo mwa kapangidwe ka amorphous zipangizo refractory ndi tinthu kukula kwa zosakwana 0.088mm, amene amakhala ngati kugwirizana kwa aggregates pa kutentha kupeza katundu thupi ndi makina ndi ntchito. Ufa wabwino akhoza kudzaza pores wa akaphatikiza, kugawa kapena kusintha ntchito processing ndi densification wa amorphous zinthu refractory.

Aggregate: amatanthauza zida zopangidwa ndimatumba okhala ndi tinthu kukula kuposa 0.088mm. Ndicho chofunikira kwambiri pakupanga mafotokozedwe amorphous ndipo chimasewera ngati mafupa. Imatsimikizira kuthupi ndi mawotchi katundu komanso kutentha kwambiri kwa zinthu zopangira zida zamatope, komanso maziko ofunikira azinthu zakuthupi ndi kuchuluka kwa ntchito.

Binder: amatanthauza chinthu chomwe chimamangirira pamodzi ndi ufa pamodzi ndikuwonetsa mphamvu. Binder ndi gawo lofunikira la zida zopangira amorphous ndipo zitha kugwiritsidwa ntchito popanga zinthu zachilengedwe, zopangidwa mwachilengedwe. Mitundu yayikulu ndi simenti, galasi lamadzi, phosphoric acid, sol, utomoni, dongo lofewa ndi ufa wosalala kwambiri.

Zowonjezera: Ndizinthu zomwe zingalimbikitse ntchito yolumikizana ndikusintha magwiridwe antchito a gawo la masanjidwewo. Ndi mtundu wa akaphatikiza refractory, mfundo zofunika za ufa refractory ndi binder, amatchedwanso zowonjezera. Monga ma plasticizers, ma accelerator, otaya, zothandizira kuwotcha, othandizira kukulira, ndi zina zambiri.

Kuphatikiza apo, gawo labwino la ufa, zimanenedwa kuti kukula kwa tinthu sikuchepera 5μm kwa ufa wabwino, komanso ochepera 1μm kwa ufa wa ultrafine.
