Izindaba

Izitini ze-alumina eziphezulu zezitofu zokuqhuma zenziwe nge-bauxite yezinga eliphezulu njengezinto eziyinhloko zokusetshenziswa, ezihlanganiswa, zicindezelwe, zomiswe bese zishiswa ekushiseni okuphezulu. Ziyimikhiqizo evimbelayo esetshenziselwa izitofu zokuqhuma zokuvala uthango.

1. Izinkomba zomzimba nezamakhemikhali zezitini ze-alumina eziphakeme

2. Zikuphi izitini ze-alumina eziphakeme ezisetshenziswa ezithandweni zomlilo?

Izitini ze-aluminium ephezulu zakhiwe emthonjeni wesithando somlilo wokuqhuma. Umthonjeni wesithando utholakala engxenyeni engenhla yesithando somlilo wokuqhuma. Ububanzi bawo bukhula kancane kancane kusukela phezulu kuya phansi ukuze buvumelane nokukhula kokushisa kweshaja futhi kuncishiswe ukungqubuzana kodonga lwesithando somlilo ekushajeni. Umzimba wesithando somlilo uhlala esithandweni somlilo wokuqhuma. 50%-60% wokuphakama okusebenzayo. Kulesi simo, ulwelwesi lwesithando somlilo ludinga ukuhlangabezana nezidingo ezinjalo, futhi izici zezitini ze-alumina eziphezulu ukuqina okuphezulu, izinga lokushisa eliphakeme lokuthambisa ngaphansi komthwalo, ukumelana ne-asidi, ukumelana ne-alkali, ukumelana okunamandla nokuguguleka kwe-slag, kanye nokumelana okuhle kokuguguleka. Kunganeliseka, ngakho-ke kufanelekile kakhulu ukuthi umzimba wesithando somlilo wokuqhuma ufakwe izitini ze-alumina eziphezulu.

Lokhu okungenhla kuyisingeniso sezitini ze-alumina eziphakeme zama-fireplaces okuqhuma. Indawo yokufakwa kwe-lining yesithando somlilo iyinkimbinkimbi futhi kunezinhlobo eziningi zezinto ezisetshenziswayo ezingaphikisi. Izitini ze-alumina eziphakeme zingenye yazo. Kunezinhlobo ezingu-3-5 zezitini ze-alumina eziphakeme ezisetshenziswayo. Izitini zikaRobert ze-alumina eziphakeme zingasetshenziswa kuma-fireplace ahlukahlukene. Uma kudingeka, sicela usithinte.
