1. Te Hanga-ā-Ringa

Ko te whakahāngai ā-ringa te tikanga tuku iho mō te hanga i ngā āputa kirihou whakakaha-muka karāhe (FRP). Ko tēnei tikanga ko te whakatakoto ā-ringa i ngā mea kua whakakīia ki te kapia.kakahu muka karāheka wharikihia rānei ki roto i tētahi pokepokea ai, ā, ka tukua kia mārō. Ko te tukanga motuhake koia tēnei: ​​Tuatahi, ka hangaia he paparanga arai o roto whai rawa i te kapia mā te whakamahi i te kapia me te kakahu muka karāhe. Kia mārō te paparanga arai, ka tangohia mai i te pokepokea ai, ā, ka hangaia te paparanga hanganga. Kātahi ka paraihia te kapia ki runga i te mata o te pokepokea ai me te arai o roto. Ka whakatakotoria ngā paparanga kakahu muka karāhe kua tapahia i mua kia rite ki tētahi mahere whakarārangi kua whakaritea, me te whakakīkī i ia paparanga mā te whakamahi i tētahi roera kia tino mārō ai. Kia tutuki te matotoru e hiahiatia ana, ka mārō te huihuinga, ā, ka wetekina.

Ko te kapia matrix mō te hanga-ā-ringa e whakamahi ana i te epoxy, i te polyester unsaturated rānei, ko te rauemi whakapakari he medium-alkali, hekakahu muka karāhe kore-kawa.

Ngā Painga: He iti ngā taputapu e hiahiatia ana, he kaha ki te hanga i ngā pīrere rerekē, ā, kāore he here ki te āhua o ngā pīrere.

Ngā Huakore: Ka taea e ngā mirumiru hau e puta ana i te wā e whakamarokehia ana te kapia te arahi ki te porosity, ka whakaiti i te kaha ā-ringa; ka iti te whai huatanga o te whakaputa; me te koretake o te mata, kāore i te whakapaia.

2. Te Whakarewatanga Kōpeketanga

Ko te whakahāngai kōpeketanga he whakatakoto i tētahi nui o te rauemi whakahāngai ki roto i tētahi whakahāngai flange, ā, ka whakamarokehia i raro i te pēhanga mā te whakamahi i tētahi mīhini pēhi. He rerekē ngā rauemi whakahāngai, ā, ka uru atu pea ki ngā muka kua oti te whakaranu, kua oti rānei te whakakī, ngā toenga kakahu muka karāhe hangarua, ngā mowhiti/rīpene kakahu muka karāhe maha-paparanga kua whakakīia ki te kapia, ngā rau SMC (whakahāngai rau) kua whakarārangihia, ngā papanga muka karāhe kua whatuhia rānei. I tēnei tikanga, ka whakahāngaihia te kōpae flange me te kaki i te wā kotahi, ka whakarei ake i te kaha o te hononga me te hanganga whānui.

Ngā Painga: He tino tika ngā āhuatanga, he ngāwari te tukurua, he pai mō te whakaputa papatipu aunoa, he kaha ki te hanga i ngā pīrere kaki-whakaiti matatini i te taahiraa kotahi, me ngā mata maeneene ataahua e kore e hiahiatia he tukatuka muri.

Ngā Huakore: He nui te utu o te pokepokea ai, me ngā herenga ki te rahi o te flange nā ngā here o te moenga pēhi.

3. Te Whakarewa Whakawhiti Resin (RTM)  

Ko te RTM he whakauru i te whakakaha muka karāhe ki roto i tētahi pokepokea kua kati, he werohanga i te kapia hei whakakī i ngā muka, ā, he whakamaroke. Kei roto i te tukanga:

• Te whakanoho i tētahi papa karaihe karāhe e ōrite ana ki te āhua o te flange ki roto i te kōhao pokepokea ai.
• Te werohanga i te kapia iti-matotoru i raro i te pāmahana me te pēhanga e whakahaerehia ana hei whakakī i te hanganga me te neke atu i te hau.
• Te whakamahana hei whakamaroke me te tango i te flange kua oti.

Ko ngā kapia he polyester kāore i te mākū, he epoxy rānei, ā, ko ngā whakakaha kei rotowhāriki tonu o te muka karāhengā papanga whatu rānei. Tērā pea ka tāpirihia ngā whakakī pēnei i te konupūmā kāponāte, te mika, te konumohe hauwai rānei hei whakarei ake i ngā āhuatanga, hei whakaiti rānei i ngā utu.

Ngā Painga: He mata maeneene, he nui te hua, he mahi pokepokea-kati (e whakaiti ana i ngā tukunga me ngā mōrearea hauora), he whakarārangi muka ahunga mō te kaha kua tino pai, he iti te haumitanga whakapaipai, me te whakaiti i te whakamahinga rauemi/pūngao.

4. Te Whakarewa Whakawhiti Resin Āwhina-Korehau (VARTM)

Ka whakarerekē te VARTM i te RTM mā te werohanga i te kapia i raro i te korehau. Ko te tukanga he hiri i te poroporo muka karāhe ki runga i te pokepokea tāne me te putea korehau, te tango i te hau mai i te kōhao pokepokea, me te kukume i te kapia ki roto i te poroporo mā te pēhanga korehau.

Ki te whakatauritea ki te RTM, ka hangaia e te VARTM ngā flange he iti ake te porosity, he nui ake te ihirangi muka, ā, he kaha ā-ringa pai ake.

5. Te whakarewa whakawhiti kapia āwhina-hau

Ko te hanga RTM āwhina-pēke hau he momo hangarau hanga anō hoki i whakawhanakehia i runga i te kaupapa o te RTM. Ko te tukanga o te whakarite i ngā flanges mā tēnei tikanga hanga koia tēnei: ​​ka whakatakotoria he preform muka karāhe āhua-flange ki runga i te mata o te pēke hau, ka whakakīia ki te hau, kātahi ka whānui ki waho ka herea ki te wāhi o te pokepokea katote, ā, ka whakakīia te preform flanges i waenganui i te pokepokea katote me te pēke hau, ka whakamarokehia.

Ngā Painga: mā te whakawhānui i te pēke hau ka taea te rere o te kapia ki te wāhanga o te puka kāore i whakakīia, kia pai ai te whakakīia o te puka e te kapia; ka taea te whakarite i te nui o te kapia e te pēhanga o te pēke hau; ka pā te pēhanga e tukuna ana e te pēke hau ki te mata o roto o te flange, ā, i muri i te whakamaroke he iti te porosity o te flange, ā, he pai ngā āhuatanga miihini. I te nuinga o te wā, i muri i te whakariteFRPMe whakamahi te tikanga whakakoi i runga ake nei hei hanga i te flange, me tukatuka hoki te mata o waho o te flange kia rite ki ngā whakaritenga o te whakamahinga o te hurihanga me te keri i roto i ngā kōhao huri noa i te porowhita o te flange.
