I ngā tau tata nei, kua piki haere tonu te whakamahinga o ngā kirihou i roto i ngā motuka. I tēnei wā, kua eke te whakamahinga o ngā kirihou motuka ki te 10% ki te 15% i Tiamana, te Hononga o Amerika, Hapani me ētahi atu whenua, ā, kua eke ētahi ki te neke atu i te 20%. Mai i ngā rauemi e whakamahia ana i roto i ngā motuka hou, ahakoa he wāhanga whakapaipai o waho, he wāhanga whakapaipai o roto, he wāhanga mahi me te hanganga rānei, ka kitea te atarangi o te hanga kirihou i ngā wāhi katoa. Ā, me te whakapai tonu i te pakeke, te kaha, me ngā āhuatanga kume o ngā kirihou hangarau, kua puta haere ngā matapihi kirihou, ngā tatau, ngā anga, tae noa ki ngā motuka kirihou katoa, ā, kei te tere haere te tukanga whakakirikiri o ngā motuka.
He aha ngā painga o te whakamahi i te kirihou hei rauemi mō ngā waka?
1.He māmā noa te hanga kirihou, ā, he tino watea te tukatuka i ngā wāhanga he uaua te āhua. Hei tauira, ina tukatukahia te papa taputapu ki ngā pereti maitai, he maha ngā wā ka hiahiatia kia tukatukahia, kia hangaia ngā wāhanga rerekē i te tuatahi, kātahi ka huihui, ka whakarewahia rānei mā te whakamahi i ngā hononga, he maha ngā tikanga e hiahiatia ana. Ka taea te hanga i te kirihou i te wā kotahi, he poto te wā tukatuka, ā, ka whakamanahia te tika.
2. Ko te painga nui o te whakamahi i ngā kirihou mō ngā rauemi motuka ko te whakaiti i te taumaha o te tinana o te motuka. Ko te mama te whāinga e whaia ana e te umanga motuka, ā, ka taea e ngā kirihou te whakaatu i tōna kaha i tēnei āhuatanga. I te nuinga o te wā, ko te taumaha motuhake o te kirihou he 0.9~1.5, ā, ko te taumaha motuhake o ngā rauemi hiato muka-whakapakari kāore e neke ake i te 2. I roto i ngā rauemi whakarewa, ko te taumaha motuhake o te maitai A3 he 7.6, ko te parahi he 8.4, ā, ko te konumohe he 2.7. Nā tēnei ka waiho te kirihou hei rauemi pai mō ngā motuka mama.
3. Ko ngā āhuatanga whakarerekētanga ngāwari o ngā hua kirihou ka mimiti i te nui o te kaha tukinga, he nui ake te pānga ārai i ngā pānga kaha, ā, ka tiaki i ngā waka me ngā pāhihi. Nō reira, ka whakamahia ngā panera taputapu kirihou me ngā wira urungi i roto i ngā waka hou hei whakarei ake i te pānga whakamarie. Ko ngā parepare o mua me muri me ngā rīpene whakapaipai tinana he mea hanga ki ngā rauemi kirihou hei whakaiti i te pānga o ngā mea o waho o te waka ki te haruru o te waka. Hei tāpiri, he mahi anō tā te kirihou ki te mimiti me te whakaiti i te wiri me te haruru, ka taea ai te whakapai ake i te whakamarie o te eke.
4. Ka taea te hanga kirihou hei kirihou me ngā āhuatanga e hiahiatia ana mā te tāpiri i ngā momo whakakī, ngā mea whakapūmau kirihou me ngā mea whakapakeke e ai ki te hanganga o ngā kirihou, ā, ka taea te whakarerekē i te kaha ā-pūkaha me ngā āhuatanga tukatuka me te whakapūtanga o ngā rauemi kia tutuki ai ngā whakaritenga o ngā wāhanga rerekē o te motuka. Hei tauira, me tino kaha te ā-pūkaha o te parepare, ko te urunga me te tuara me hanga ki te pahuka polyurethane ngohengohe.
5.He kaha te ātete o te kirihou ki te waikura, ā, e kore e waikura mēnā ka pakaru i te rohe. Heoi, ina pakaru te mata peita, kāore rānei i te pai te ārai-waikura i roto i te hanga maitai, ka ngāwari te waikura me te pirau. He nui ake te ātete o ngā kirihou ki te waikura ki ngā waikawa, ki te kawakore, me te tote i ērā o ngā pereti maitai. Mēnā ka whakamahia ngā kirihou hei uhi tinana, he tino pai mō te whakamahi i ngā wāhi he nui ake te parahanga.
I te nuinga o te wā, kua whanake ngā kirihou o ngā motuka mai i ngā wāhanga whakapaipai noa ki ngā wāhanga hanganga me ngā wāhanga mahi; kei te whanake ngā rauemi kirihou o ngā motuka ki ngā rauemi hiato me ngā koranu kirihou he kaha ake, he pai ake te pānga, he tino tere te rere. He roa tonu te ara kei mua i te whakatairanga i ngā motuka kirihou a meake nei. Ehara i te mea he take haumaru anake, engari he take anō hoki pēnei i te tawhito me te hangarua. Me whakapai ake tēnei i roto i te hangarau.
