muka papara tapatapahi he muka kohuke kore-waro, he iti iho i te 50mm te roa, he mea tapatapahi mai i te rauemi turanga muka basalt e rite ana, ā, ka taea te horapa ōrite ki roto i te raima. E ai ki tōna whakamahinga, ka taea te wehewehe ki te raima muka ātete-pakaru (BF), te muka whakapakari uaua (BZ) me te muka ātete-ngatata moata (BSF).
Ko te mahi matua o te raima muka papara tapatapahi ko te tāpiri i ngā muka papara tapatapahi tonu, motumotu rānei ki te raima i roto i te nui e tika ana, ā, i roto i te huarahi e tika ana, hei whakapai ake i te pakari me te kaha kume o te raima, me te pupuri tonu i te kaha pēhi taketake o te hanganga raima.
Ko te āhua o te muka papara tapatapahi e whakakī ana i te āputa i runga i ngā rauemi me ngā tikanga, ā, he mahi nui tāna ki te whakatairanga i te whakapakari me te te whakapakari i te raimaKo tōna tūranga i roto i te whakapakari me te whakakaha raima e whakaatuhia ana i roto i ngā āhuatanga e whai ake nei:
(1) Ka taea e ngā miro papara tapatapahi te whakamahi katoa i ō rātou painga horahanga mata me te rahinga, kia aukatia ai ngā kapiti moroiti kia kore ai e motu, ā, he mea whakamiharo ngā hua. I taua wā anō, ka wikitoria i ngā ngoikoretanga o ētahi atu muka hangai pērā i te iti o te mātotoru, te iti o te kaha kume me te ngāwari o te tango, pērā i te ngāwari o te tango atu i te wā e whānui ana ngā kapiti, ka taea ai te aukati i te whānui o ngā kapiti moroiti o mua me te putanga mai o ngā kapiti hou. He pānga anō tō te rewa me te ātete ki te wai.
(2) Haunga tōna rite ki te muka maitai, ka taea e te muka papara tapatapahi te whakamahi i tōna modulus teitei me te kaha kume kotahi hei karo i te whānui o ngā kapiti, ā, ka taea hoki e ia te ārai i te ngāwari o te here o ngā muka maitai i te wā e whakaoho ana, kāore e pai mō te papu. He uaua te tukanga hanga.
(3) He nitrocellulose noa te muka basalt tapatapahi, he hototahi ā-taiao, ā, nā te mea he rite te matotoru ki te raima sima me te moata, ko te matotoru kei waenga i te 2.63-2.8g/m³; he pai te mahi, ka taea te tohatoha ōrite i ngā muka basalt tapatapahi i muri i te whakauru ki roto i te hanganga raima.
(4) Kua whakarerekētia te mata o te muka papara tapatapahi, ā, he momo "muka kore mahi", he tino ātete ki te pāmahana teitei, ki te waikura me te ātete pānga. Ka taea e ia te pupuri i te pumau i roto i te pāmahana teitei me te taiao waikura teitei, ā, ka taea te whakapai ake i te ātete ki te whakarerekētanga o te hanganga sima. Nō reira, ka taea e te muka papara tapatapahi te urutau ki te taiao uaua i ngā wāhanga katoa o te whakaranu raima, te ringihanga, te whakapūmau me te whakamahinga, me te whakapai ake i te roa o te raima.
