Paipa Epoxy FRP
Whakaahuatanga Hua
Ko te paipa epoxy FRP e mōhiotia whānuitia ana ko te paipa Epoxy Whakakaha muka karāhe (GRE). He paipa rauemi hiato mahi-teitei, i hangaia mā te whakamahi i te takai miro, i tētahi tukanga rite rānei, me ngā muka karāhe kaha-teitei hei rauemi whakakaha me te kapia epoxy hei matihiko. Ko ōna painga matua ko te ātete tino pai ki te waikura (ka kore e hiahiatia he paninga tiaki), te mama me te kaha teitei (ka māmā ake te tāutanga me te kawe), te kawe wera tino iti (ka whakarato i te whakamarumaru wera me te penapena pūngao), me te pakitara o roto maeneene, kāore e tauine. Nā ēnei āhuatanga ka waiho hei whakakapinga pai mō ngā paipa tuku iho i roto i ngā rāngai pēnei i te hinu, te matū, te miihini moana, te whakamarumaru hiko, me te maimoatanga wai.
Ngā Āhuatanga o te Hua
He pai ake te huinga o ngā āhuatanga o te Paipa Epoxy FRP (Glass Fiber Reinforced Epoxy, GRE rānei) ki te whakataurite ki ngā rauemi tuku iho:
1. Ātete Tino Pai ki te Waikura
- Ārai Matū: He tino ātete ki te whānuitanga o ngā momo waikura, tae atu ki ngā waikawa, ngā kawakore, ngā tote, ngā parakaingaki me te wai moana.
- Kore-Tiaki: Kāore e hiahiatia he paninga tiaki ā-roto, ā-waho rānei, he tiakitanga katote rānei, ā, ka whakakorea rawatia ngā tiaki me ngā mōrearea e pā ana ki te waikura.
2. Taumaha Mama me te Kaha Teitei
- Te Matotoru Iti: 1/4 ki te 1/8 noa iho te taumaha o te paipa rino, e whakamāmā ana i ngā mahi kawe, te hiki, me te tāutanga, e whakaiti ana i ngā utu kaupapa katoa.
- Kaha Mīhini Tino Pai: He kaha teitei ki te kume, ki te piko, me te pānga, ka taea te tu atu ki ngā pēhanga whakahaere teitei me ngā kawenga o waho.
3. Ngā Āhuatanga Waipēhi Pai rawa atu
- Pūngao Maeneene: He iti rawa te waku o te mata o roto, ā, ka whakaitihia te ngaronga o te upoko wai me te whakapaunga pūngao papu ki te whakatauritea ki ngā paipa whakarewa.
- Kore-Whakanui: Ka ātete te pakitara maeneene i te piri o te unahi, te paru, me te poke koiora (pērā i te tipu o te moana), ka mau tonu te pai o te rere o te wai i te roanga o te wā.
4. Ngā Āhuatanga Wera me te Hiko
- Ārai Wera: He tino iti te kawe wera (tata ki te 1% o te maitai), e whakarato ana i te ārai wera tino pai hei whakaiti i te ngaronga, te pikinga rānei o te wera mō te wai e haria ana.
- Ārai Hiko: He pai rawa ngā āhuatanga ārai hiko, he mea haumaru, he mea pai hoki mō te whakamahi i roto i ngā taiao hiko me te whakawhitiwhiti kōrero.
5. Te pakari me te iti o te utu mō te huringa ora
- Roa te Ora Ratonga: I hangaia mō te roanga ratonga o te 25 tau, neke atu rānei i raro i ngā tikanga whakahaere noa.
- Te Tiaki Iti: Nā te ātete ki te waikura me te tauine, kāore e hiahiatia he tiaki auau mō te pūnaha, ā, he iti te utu mō tōna huringa ora katoa.
