Tātari Rapa/ Tātari Rapa
Te Kōwhiringa o te Tātari Rapa
1. Tātari rapa pēhanga – He pai mō te ranunga rapa ngohengohe kāore e hiahia kia whakaranua anō.
Āhuatanga: ngāwari ki te horoi, ka taea te whakaputa mā roto i te tātari harore 200, he nui ake te putanga.
2. Tātari rapa tīwiri – He pai mō ngā momo rapa katoa mō te umanga roera.
Āhuatanga: ka taea te tātari i te whānuitanga o ngā matū rapa.
1) Momo tīwiri kotahi:
Momo tīwiri kotahi paerewa – He pai mō te matū i waenga i te 25-95Sh-A, engari kāore mō te rapa matotoru nui, pērā i te silicon me ētahi atu.
Whakaūtia te momo whāngai tīwiri kotahi – He pai mō ngā momo rapa katoa i waenga i te 25-95Sh-A, ahakoa mō ngā rapa matotoru teitei, pērā i te silicon, EPDM, Hypalon, me ētahi atu.
2) Momo tīwiri-rua:
Whakaūtia te momo whāngai takirua-tīwiri – He pai mō ngā momo rapa katoa i waenga i te 25-95Sh-A, ahakoa mō te rapa matotoru teitei, pērā i te silicon, EPDM, Hypalon, me ētahi atu.
Whakaūtia te whāngai tīwiri-rua me te momo TCU – He pai mō te matū i waenga i te 25-100Sh-A, he tino pai mō te matū tairongo pāmahana.

Te Kōwhiringa o te Ōwehenga Roa-Diameter:
1. Mena he onepu kei roto i te rapa, me whiriwhiri te ōwehenga roa-diameter o te tīwiri mō te mea nui ake.
2. Ko te painga o te ōwehenga roa-whānui o te tīwiri ko te roa o te wāhanga mahi o te tīwiri, he kirihou te rauemi, he ōrite te whakaranu, he pēhanga teitei te rapa, ā, he pai te kounga o te hua. Heoi, ki te roa te tīwiri, ka ngāwari te tahu i te rapa, ā, ka uaua te tukatuka i te tīwiri, ā, ka piki ake te kaha o te whakaputa.
3. Ko te tīwiri e whakamahia ana mō te mīhini rapa whakaputa whāngai wera he whānui te roa, ā, ko te tīwiri mō te mīhini rapa whakaputa whāngai matao he whānui te roa, he whānui te roa, he whānui te 8 ki te 12 ngā wā.
Ngā painga o te whakanui ake i te ōwehenga roa-diameter
1) Kua pēhia katoatia te tīwiri, ā, ka taea te whakapai ake i ngā āhuatanga ā-tinana me ngā āhuatanga ā-pūkaha o ngā hua.
2) He pai te kirihou o ngā rauemi me te kounga pai o ngā hua.
3) Whakanuia te rōrahi whakaputa mā te 20-40%. I taua wā anō, ko te pihi āhua o te tīwiri me te ōwehenga roa-whānui he iti te pari, he papatahi, ā, he pumau te rōrahi whakaputa.
4) He pai mō te hanga paura, pērā i te ngongo whakaputa paura PVC.
Ngā huakore o te whakanui ake i te ōwehenga roa-diameter:
Mā te whakanui ake i te ōwehenga roa-diameter ka uaua te hanga tīwiri me te huihuinga o te tīwiri me te oko. Nō reira, kāore e taea te whakanui ake i te ōwehenga roa-diameter me te kore herenga.
