Alumina oo firfircoon sida qalajiyaha ee ku jirta soo saarista korontada ee qalajiyaha hawada

Alumina-da firfircoon ee qalajiyeyaasha hawada ayaa la isticmaalaa marka shuruudaha hoos u dhaca cadaadiska iyo bedka dusha sare ay u dhexeeyaan 1/8" iyo 1/4" walxo. Waxay ku habboon tahay inta badan nidaamyada. Alumina-da firfircoon waa qaab daloolo leh oo aluminium oksaydh ah. Waxay leedahay meel sare oo dusha sare ah oo nuugta uumiga iyada oo aan wax isbeddel ah ku iman qaabkeeda.

Haddii cabbirka alumina-da firfircoon aan la aqoon ama la cayimin, cabbirka 1/8″ (2-5mm) badanaa waa mid ku qanacsan. Si kastaba ha ahaatee, haddii alumina-da firfircoon loo isticmaalo qalajiyaha dib u soo nooleeya oo aan la cabbiri karin shaashadaha haynta qalajinta, cabbirka 1/4″ (5-10mm) waa in loo isticmaalaa taageero sariir (lakab 6″ ah).

Qalajiyaha alumina ee firfircoon ee heerka warshadaha ayaa si weyn loogu isticmaalaa qalajiyeyaasha hawada ee la cadaadiyey. Alumina-da firfircoon waxaa loogu talagalay qalajiyeyaasha hawada ee la kululeeyay iyo qalajiyeyaasha hawada ee la cadaadiyey ee aan kulaylka lahayn / cadaadiska lahayn. Dwpoints ilaa -40°F iyo ka hooseeya waxaa lagu gaari karaa alumina firfircoon iyadoo ku xiran naqshadda qalajiyaha iyo xaaladaha hawlgalka. Alumina-da firfircoon ee XR101 waa goob siman oo alumina firfircoon oo ay soo saarto habka wax soo saarka ee gaarka ah.

Alumina-da firfircoon waa nadiifiye aad u fiican oo lagu qalajiyo dareere iyo gaasas kala duwan. In kasta oo dhammaan molecules-ku ay ilaa xad ku milmaan alumina-da firfircoon ee firfircoon, molecules-yadaas leh polarity-ga ugu sarreeya ayaa si gaar ah loo nuugaa. Xaaladaha qulqulka sida cadaadiska, uruurinta iyo miisaanka molecules-ka ee molecules-ka, heerkulka iyo molecules-ka isku haya goobta ayaa saameeya hufnaanta nuugista.
