He momo rauemi hiato hou te paipa FRP, ko tōna tukanga hanga he mea hanga i runga i te nui o te kapia o te muka karāhe e takai ana i ia paparanga, i ia paparanga, kia rite ki te tukanga, ka hangaia i muri i te whakamaroke i te pāmahana teitei. He tika ake, he matatau ake te hanganga pakitara o ngā paipa FRP, ka taea te whakamahi i ngā rauemi pēnei i te muka karāhe, te kapia me te kaiwhakaora, e kore e tutuki noa i te kaha me te pakari e whakamahia ana, engari ka whakarite hoki i te pumau me te pono o ngā paipa FRP.
Ngā āhuatanga hangarau
1. Te tukanga whakaputa takai tonu
E toru ngā momo o te tukanga whakapūtanga takai tonu: te takai maroke, te takai mākū me te takai maroke-haurua, e ai ki te āhua ā-tinana me te āhua matū o te hanganga kapia i te wā e whakapūtanga ana te muka. Ko te takai maroke he whakamahi i te miro prepreg, i te rīpene rānei kua tukatukahia i mua i te prepreg, ka whakamahanahia ki runga i te mīhini takai hei whakangawari i te āhua wai matotoru, kātahi ka takai ki runga i te pokepoke matua. Ko te āhuatanga nui o te tukanga takai maroke ko tōna pai whakaputa teitei, ā, ka taea e te tere takai te eke ki te 100-200m/min; ko te takai mākū he takai tika i te paihere muka (rīpene rite ki te miro) ki runga i te mandrel i raro i te mana whakahaere i muri i te tōia ki te kāpia; Ko te takai maroke me tāpiri he taputapu whakamaroke hei tango i te whakarewa i roto i te miro kua tōia i muri i te tōia o te muka ki roto i te pokepoke matua.
2. Tukanga whakakoi whakaora ā-roto
He tukanga whakapūtanga whai hua te tukanga whakamaroke ā-roto mō ngā rauemi muka whakapūtanga werawera. Ko te pokepoke matua e hiahiatia ana mō te tukanga whakamaroke ā-roto he hanganga porotaka kau, ā, he mea hanga ngā pito e rua ki tētahi momo whakawhāiti hei whakahaere i te whakapūtanga. Ka tāutahia he paipa maitai kau ki roto i te pokepoke matua, arā, te whakamahana. Mō te ngongo matua, ka kati tetahi pito o te ngongo matua, ā, ka tuwhera tetahi pito hei putanga mamaoa. Ka tohatohahia ngā kōhao iti ki te pakitara o te ngongo matua. Ka tohatohahia ngā kōhao iti ki ngā hauwhā e whā mai i te wāhanga tuaka. Ka taea e te pokepoke matua te huri huri noa i te kakau, he mea watea mō te takai.
3. Pūnaha whakakore
Hei whakakore i ngā ngoikoretanga maha o te tangohanga ā-ringa, kua hangaia e te raina whakaputa paipa maitai karāhe hou he pūnaha tangohanga aunoa. Ko te hanganga miihini o te pūnaha tangohanga he mea hanga nui mai i te taputapu taraka tangohanga, he rango raka, he rawhi waku tangohanga, he tokotoko tautoko me te pūnaha hau. Ka whakamahia te taraka tangohanga hei whakakī i te pokepokea matua i te wā e takai ana, ā, ka raka te rango i te wā e tangohanga ana. Ka hoki whakamuri te tokotoko piston, ka hiki ake te pōro maitai here i te taha hiku, ka wetekina te poro, kātahi ka whakaotihia te tukanga here poro mā te kaha waku o te hurihuri poro me te rango, ā, hei whakamutunga ka raka te rango me ngā kokopi waku tangohanga. Wehea te tinana ngongo mai i te pokepokea matua me ētahi atu taputapu hei whakaoti i te tukanga tangohanga.
Ngā tirohanga whanaketanga ā muri ake nei
He whānui te whānuitanga o ngā tono hua me te nui o te mākete
He tino ngāwari te hoahoa i ngā paipa FRP, ā, ka taea te whakatutuki i ngā hiahia o ngā momo mara maha. Ko ngā mara tono noa ko te hanga kaipuke, te hanga taputapu miihini moana, te hinu matū, te hau māori, te hiko, te tuku wai me te rerenga wai, te hiko karihi, me ētahi atu, ā, he nui te tono a te mākete.
