E toru ngā wāhanga o tōna hanganga: te matihiko, te whakapakari, me ngā tāpiringa, me ngā mahi kua tautuhia mārama. Ko te rauemi matihiko,kapia phenolic, e 40%-60% te nui, e hanga ana i te "anga" o te rauemi, ā, e whakarato ana i te ātete pāmahana teitei, te ātete waikura, me te piri, e whakatau ana i ngā āhuatanga taketake o te rauemi. Ko te rauemi whakapakari, te muka karāhe, e 30%-50% te nui, ko te nuinga he muka poto (1-5mm te roa), e mahi ana pērā i ngā "pae maitai" hei whakapai ake i te kaha kume me te piko me te ārai i te pakarukaru o te rauemi. Kei roto i te pūnaha tāpiri ngā kaihoko whakaora, ngā hinu whakahinuhinu, ngā whakakī, me ngā kaihoko honohono, me te ōwehenga katoa o te 5%-10%, e whakarite ana i te tukatuka me te mahi.

Pūhui whakarewa muka karāhe phenolicHe rauemi whakakoi tēnei i hangaia mā te whakamahi i te kapia phenolic hei anga, te muka karāhe hei whakakaha, me te tāpiri i ngā wāhanga āwhina pēnei i ngā kai whakaora, ngā hinu whakahinuhinu, me ngā whakakī, mā roto i ngā tukanga motuhake tae atu ki te whakaranu, te whakakī, me te whakamaroke. E rua ngā painga o te kapia phenolic me te muka karāhe. He tino pai te ātete wera, te ātete waikura, me te whakamarumaru o te kapia phenolic, engari ka whakapai ake te muka karāhe i ngā āhuatanga miihini o te rauemi, pēnei i te kaha, te pakari, me te ātete pānga. Ka taea te tukatuka i tēnei rauemi ki ngā āhua uaua mā roto i ngā tukanga whakakoi pēnei i te whakakoi pēhi me te whakakoi werohanga, ā, he whānuitia te whakamahinga i roto i ngā mara maha pēnei i te hiko, te motuka, te mīhini, me ngā ahumahi matū. I roto i te mara hiko, ka taea te whakamahi hei hanga i ngā pana whakamarumaru, ngā tūhono, me ngā wāhanga motuka; i roto i te mara motuka, ka taea te whakamahi hei hanga i ngā wāhanga ātete-kakahu pēnei i ngā mata mamau me ngā papa parai; i roto i te mara mīhini, ka taea te whakaputa i ngā wāhanga hanganga pēnei i ngā taputapu me ngā whare pupuri. He māmā te tukanga whakakoi, he teitei te pai o te whakaputa, ā, he pai te pumau o ngā āhuatanga o ana hua, ā, he utu whaitake te utu. He rauemi hangarau tēnei me te mahi whānui tino pai, ka taea te whakatutuki i ngā whakaritenga mahi rauemi kanorau o ngā ahumahi rerekē, me te whakarato tautoko rauemi pono mō te rangahau me te whanaketanga me te whakaputa i ngā hua e pā ana.
