He kupu whakataki ki te para witi
Ko te para witi he hua e tukuna ana mai i te oumu pupuhi i muri i te whakarewanga o ngā wāhanga kore-ferrous i roto i te rino, te kōka me te pungarehu i roto i te waro werohanga i te whakarewanga o te rino poaka i roto i ngā umanga rino me te maitai. Ko te nuinga he poraka tioata, he honikoma, he tokotoko rānei. Ko te nuinga he kiko angiangi me te tinana vitreous, he kōwhai mārama (he iti noa ngā tioata kakariki pouri), he kanapa karāhe, he kanapa hiraka rānei. Ko te pakeke Mohs he 1 ~ 2, (kohikohi taiao) ko te taumaha motuhake he 0.8 ~ 1.3t/m3. E rua ngā huarahi matua: te tinei i te para wai puna me te tinei i te wai o mua o te oumu. He āhuatanga sima waipēhi pea tōna. I raro i te mahi a te sima clinker, te raima, te gypsum me ētahi atu whakahohe, ka taea e ia te whakaatu i te mahi sima pakeke o te wai. Nō reira, he rauemi mata sima kounga teitei.
Te whakamahinga o te para witi
1. Te whakamahinga o te para witi i roto i te umanga sima:
He āhuatanga sima waipēhi pea tōna. Ka taea te whakamahi hei ranunga sima, hei sima kore-kirini rānei. Ko ngā momo sima e hangaia ana ko te sima Portland para, te sima gypsum para, te sima raima para, me ētahi atu.
2. Te whakamahinga o te para witi i roto i te raima arumoni:
Hei ranunga kohuke mō te raima, ka taea e te paura para witi te whakakapi i te sima i te nui ōrite. Ka tāpirihia tika ki te raima arumoni. I runga i te rerekētanga o te mahi me te horahanga mata motuhake, ka tino pai ake te mahi a te raima i konatunatua ki te paura moroiti para witi i roto i tētahi ōwehenga. He tino pai te paura para witi mō ngā kaupapa motuhake pēnei i ngā whare teitei, ngā tāhuna, ngā taunga rererangi, ngā whare raro i te wai me ngā whare raro whenua.

Te tātari i ngā tauira mira huri
Mira roera poutū:
Ka taea e ngā taputapu nui me te putanga nui te whakatutuki i te whakaputanga nui.mira paura parahe tino pumau. Ngā ngoikoretanga: he nui te utu haumi mō ngā taputapu.
Wāhanga I: Te kuru i ngā rauemi mata
Ka kuruhia te para witi nui e te mīhini kuru kia tae ki te matotoru whāngai (15mm-50mm) ka taea te uru ki te mira huri.
Wāhanga II: Te Hurihuri
Ka tukuna ngā rauemi iti o te para witi kuru ki te pūwero rokiroki e te ararewa, kātahi ka tukuna ki te rūma huri o te mira kia ōrite, kia rahinga hoki e te kaiwhāngai hei huri.
Wāhanga III: Te Whakarōpūtanga
Ka mākahia ngā rauemi kua mira e te pūnaha māka, ā, ka mākahia te paura kāore i te tino tika e te kaiwhakarōpū ka whakahokia ki te mīhini matua kia hurihia anō.
Wāhanga V: Kohinga o ngā hua kua oti
Ka rere te paura e rite ana ki te matotoru o te paura mā roto i te paipa me te hau, ka tomo ki te kaikohi puehu hei wehe me te kohikohi. Ka tukuna te paura kua kohia ki te whare pupuri hua kua oti mā te taputapu kawe mā te putanga tuku, kātahi ka tākaihia e te waka tāke paura, e te tākai aunoa rānei.
Ngā tauira tono o te tukatuka paura para witi
Tauira me te maha o ēnei taputapu: 1 huinga o HLM2100
Te tukatuka rauemi mata: Para
Te pai o te hua kua oti: 200 mata D90
