He rauemi makutu - muka karāhe

Neke atu i te 10 tau a Shanghai Ruifiber Industry Co., Ltd e arotahi ana ki te muka karāhe kua whakakīia, he nui ō mātou wheako ki te whakaputa i ngā taonga muka karāhe e pā ana.

Ko ngā rauemi mata taketake mō ngā hua muka karāhe he momo kohuke taiao me ngā matū hanga. Ko ngā kai matua ko te onepu silica, te kōhatu papa, me te pungarehu houra. Ko ētahi atu kai ko te alumina kua whakapūkarahia, te borax, te feldspar, te nepheline syenite, te magnesite, me te uku kaolin, me ētahi atu. Ka whakamahia te onepu silica hei hanga karāhe, ā, ko te pungarehu houra me te kōhatu papa te mea nui hei whakaiti i te pāmahana rewa. Ka whakamahia ētahi atu kai hei whakapai ake i ētahi āhuatanga, pērā i te borax hei ātete ki ngā matū. Ko te karāhe para, e kiia ana ko te cullet, ka whakamahia hoki hei rauemi mata. Me ata paunatia ngā rauemi mata ki ngā rahinga tika, ā, me whakaranu pai (e kiia ana ko te batching) i mua i te whakarewanga ki roto i te karāhe.

Te tukanga hanga
Te whakarewa Te hanga hei mukaTe miro tonu Te muka-tīpako Te muka tapatapahi
Wūru karāhepaninga tiaki Te hanga hei āhua

Mō ngā paninga, haunga ngā mea here, me whakamahi ētahi atu paninga mō ngā hua muka karāhe. Ka whakamahia ngā hinu whakahinuhinu hei whakaiti i te pakū o te muka, ā, ka rehu tika ki runga i te muka, ka tāpirihia rānei ki roto i te mea here. I ētahi wā ka rehuhia he hanganga ārai-pūmau ki runga i te mata o ngā whāriki whakamahana muka karāhe i te wā e whakamatao ana. Mā te hau whakamatao e kumea ana mā roto i te whāriki ka uru te matū ārai-pūmau ki roto i te matotoru katoa o te whāriki. E rua ngā wāhanga o te matū ārai-pūmau—he rauemi e whakaiti ana i te whakaputanga o te hiko pūmau, me te rauemi e mahi ana hei aukati me te whakaū i te waikura.
Ko te rahinga he paninga e pania ana ki ngā muka kakahu i te wā e hangaia ana, ā, ka taea te whakauru i tētahi, neke atu rānei o ngā wāhanga (ngā hinu whakahinuhinu, ngā here, ngā kaihoko hononga rānei). Ka whakamahia ngā kaihoko hononga ki ngā miro ka whakamahia hei whakakaha i ngā kirihou, hei whakakaha i te hononga ki te rauemi kua whakakahangia.
I ētahi wā ka hiahiatia he mahi whakaoti hei tango i ēnei paninga, hei tāpiri rānei i tētahi atu paninga. Mō ngā whakakaha kirihou, ka taea te tango i ngā rahinga mā te wera, mā ngā matū rānei, ā, ka tāpirihia he mea hono. Mō ngā mahi whakapaipai, me whakamahana ngā papanga hei tango i ngā rahinga, hei whakapūmau hoki i te whatu. Kātahi ka pania ngā paninga turanga tae i mua i te tae, i te tānga rānei.
