Te Whakamahinga o te Poari Muka Uku
He iti te kawe wera me te iti o te rokiroki wera te papa muka uku, ā, he pakari te papa muka uku, he konumohe silica pakari te kaha, e whakamahia ana mō ngā hononga whānui, ngā tauhohenga pāmahana teitei, ngā taputapu whakamahana, ngā arai muri o te ahumahi konganuku kore-ferrous.
Kaihanga Papa Muka Uku mai i te Wheketere Whakamātao RS
He kaihanga papa muka uku ngaio a RS refractory factory i whakatūria i te tīmatanga o ngā tau 1990 o te rautau rua tekau. Neke atu i te 20 tau te wheketere muka uku RS e tohunga ana ki ngā papa muka uku refractory. Mena he hiahia nui tōu ki ngā papa muka uku, he pātai rānei mō ngā papa muka uku e pā ana ki ngā tohu ā-tinana me ngā tohu matū, tēnā whakapā mai ki a mātou mō te kore utu.
