He rite te āhua o te miro whatu whakatakotoranga ki tētahi whatunga, ki tētahi whatunga rānei. He mea hanga mai i ngā hua miro tonu (ngā miro). Hei pupuri i ngā miro ki te tūranga tika e hiahiatia ana, me hono ēnei miro. He rerekē ki ngā hua whatu, ko te whakapiri i ngā miro whenu me ngā miro whatu i roto i ngā miro whatu whakatakotoranga me mahi mā te hononga matū. Ka whakatakotoria noa ngā miro whatu ki runga i te raro. Ka tutuki tēnei mā te tukanga hanga.
Ko ngā whatu miro whakatakotoranga he angiangi ake i te 20 – 40% i ngā mea whatu i hangaia mai i te miro kotahi, ā, he ōrite te hanganga.
He maha ngā paerewa Pākehā e hiahia ana kia iti rawa te hipoki rauemi mō ngā kiriuhi tuanui i ngā taha e rua o te paninga. Mā ngā paninga kua whakatakotoria ka āwhina i te whakaputa hua angiangi me te kore e whakaae ki ngā uara hangarau kua heke. Ka taea te penapena neke atu i te 20% o ngā rauemi mata pēnei i te PVC, te PO rānei.
Ko ngā kiriuhi anake e āhei ai te hanga i tētahi kiriuhi tuanui papa-toru tino angiangi, ōrite, (1.2 mm) e whakamahia pinepinetia ana i Ūropi Waenganui. Kāore e taea te whakamahi i ngā papanga mō ngā kiriuhi tuanui he angiangi ake i te 1.5 mm.
Kāore e tino kitea te hanganga o te whatu whiri i roto i te hua whakamutunga, pērā i te hanganga o ngā rauemi whatu. Nā tēnei ka maeneene ake, ka ōrite ake te mata o te hua whakamutunga.
Mā te mata maeneene o ngā hua whakamutunga kei roto ngā kiriuhi kua whakatakotoria ka taea te whakarewa, te whakapiri rānei i ngā paparanga o ngā hua whakamutunga tetahi ki tetahi kia ngāwari ake, kia mau hoki.
Ka roa ake te ātete o ngā mata maeneene ki te paru, ā, ka mau tonu.
Mā te whakamahinga o ngā mea kore-whatu kua whakakahangia ki te muka karāhe ka taea te tere ake i te mīhini mō te hanga pepa tuanui bitumen. Nō reira, ka taea te ārai i ngā haehae e pau ana te wā me te mahi i roto i te wheketere pepa tuanui bitumen.
Ka tino whakapaitia ngā uara ā-pūkaha o ngā pepa tuanui uku mā te whakamahi i ngā kiriuhi.
Ko ngā rauemi e ngāwari ana te haehae, pērā i te pepa, te pepa konukōre, ngā kiriata rānei mai i ngā momo kirihou, ka āraihia kei pakaru mā te whakawhāiti i ēnei ki ngā paninga kua whakatakotoria.
Ahakoa ka tukuna pea ngā hua whatu ki te āhua loomstate, ka whakakīia tonutia he kiriuhi kua whakatakotoria. Nā tēnei, he nui ō mātou mōhiotanga mō te mea e pai ana mō ngā mahi rerekē. Mā te whiriwhiri i te piripiri tika ka tino pai ake te hononga o te kiriuhi kua whakatakotoria ki te hua whakamutunga.
Nā te mea kei te taha kotahi tonu o ngā miro whatu te miro o runga me raro i roto i ngā miro whatu, ka noho tonu ngā miro whatu i raro i te taumahatanga. Nō reira, ka mimiti tonutia ngā mana taumahatanga i te ahunga taumahatanga. Nā tēnei pānga, he maha ngā wā ka iti haere te roa o ngā miro whatu. Ina whakarārangihia he miro i waenganui i ngā paparanga kiriata e rua, i ētahi atu rauemi rānei, ka iti ake te piri e hiahiatia ana, ā, ka pai ake te piri o te raina. Me whakamaroke tonu te hanga o ngā miro whatu i te wera. Ka hua ake tēnei i te mimiti o te polyester me ētahi atu miro thermoplastic, ka pai ake ai ngā maimoatanga e whai ake nei mā te kiritaki.
Mena he pātai āu mō ngā hua katoa o ngā mea kua whakatakotoria ki runga i ngā papa rakau me ngā hua muka karāhe, pērā i
he mea hanga ki te polyester scrim me te here PVOH,
he mea hanga ki te polyester scrim me te hononga PVC,
he mea whakairo ki te muka karāhe me te here PVOH,
he mea whakairo ki te muka karāhe me te here PVC,
Nau mai ki te whakapā mai i ngā wā katoa!
