1. Kupu Whakataki

I roto i te tuku me te tukatuka i ngā mōhiohio, he mahi nui tā ngā Taura Muka Whatu (OFC). E kiia ana ko rātou ngā huarahi whakawhitiwhiti kōrero me ngā waea matihiko. Nō reira, he mea tino nui kia whakamanahia e rātou ngā hononga haumaru i ngā wā katoa. Heoi, i ētahi wā, ka mōrearea pea te roanga mahi o tētahi OFC e ngā kiore, hei tauira, ina tāutahia ngā OFC ki roto i ngā paipa e taea ai e ngā kiore te uru atu. I roto i ēnei taiao me tiaki ngā OFC, nā te mea he āhua noa iho tō ngā kiore ki te ngau me te whakaeke i ngā OFC ina aukatihia tō rātou putanga i roto i ēnei paipa.

Mō te hoahoa taura tino pai, he pai ake ki ngā kaihanga taura te whakamahi i tētahi rauemi e whakakotahi ana i ngā āhuatanga whakapakari me te tiaki i ngā kiore. E hiahia ana hoki rātou kia ngāwari, kia māmā hoki ngā OFC, ā, kia iti te diameter. Ko ngā rauemi hei whakapakari i ngā OFC dielectric ko te aramid me te E-glass, engari he iti ake te rahi. He tino rongonui te whakamahinga o te aramid, ā, kei te tere piki haere tonu nā te mea he pai te whakakotahitanga o ngā āhuatanga miihini me te matū me ōna āhuatanga tukatuka pai, ka hua ake he OFC tino iti te utu me te mahi tino pai me te pono mō te wā roa. Heoi, kua ara ake te pātai mēnā ka whakarite te E-glass me te aramid i te tiaki i ngā kiore kia rawaka. He uaua ki te tiki whakautu mārama mai i ngā kaiwhakamahi mutunga OFC. Hei tauira, i whakaatuhia e ngā wheako o ngā kaiwhakamahi mutunga OFC i Switzerland i ētahi wā i tino kino te pakaru o ngā taura E-glass me te aramid i ngā kiore, ā, kāore i pai te mahi. Hei whakamārama i te āhuatanga mō te tiaki i ngā kiore, me te tautoko i ngā kaihanga o ngā OFC dielectric, i whakatau mātou me tētahi o ā mātou kiritaki Huiterangi ki te karanga i tētahi whare rangahau motuhake, arā, ko TNO (he whakahaere Tatimana mō te rangahau pūtaiao tono), ki te whakahaere i tētahi rangahau i raro i ngā āhuatanga mahi hei whakamātautau i te ātete kiore o ētahi momo OFC.

2. Whakamātautau

Te whakatūnga whakamātautau

Hei whakamātautau i te ātete o ngā OFC ki ngā kiore, i whakamahia e te TNO ngā kiore Sprague Dawley i roto i ngā whare herehere i hangaia mō tēnei rangahau. I wehea ēnei whare herehere kia rua ngā wāhanga mā te wehewehe me te kōhao porowhita hei hono i ngā wāhanga e rua (tirohia te Pikitia 1). I whakamāramahia tētahi o ngā wāhanga, ā, i whakapōuritia tētahi. I roto i ngā whakamātautau, i āraia te tomokanga ki te wāhanga pōuri, te wāhi i noho ai te kai a ngā kiore, e ngā OFC i te whakamātautau. Nā te mea he pai ake ki ngā kiore te taiao pōuri, ka noho te nuinga o te wā ki te taha pōuri. Nō reira, e rua ngā whakaohooho kia uru atu ai ngā kiore ki te wāhanga pōuri. I te wā whakamātautau katoa, i wātea te urunga o ngā kiore ki te wai. I muri i te taunga o ngā kiore ki ngā āhuatanga o roto i ngā whare herehere, ka tīmata ngā whakamātautau tuatahi.

Pikitia 1: Kua wehea te whare herehere whakamātautau kia rua ngā wāhanga.

I te tīmatanga o ngā whakamātautau, e toru ngā kiore i whakanohoia ki roto i ngā wāhanga whakamārama o ia whare herehere mō ngā rā e rua i muri mai, ā, i āraia te kōhao i te ārai e te hoahoa OFC i te whakamātautau (tirohia te Pikitia 2). I muri i tēnei wā, i nekehia ngā kiore ki ētahi atu whare herehere mō ngā rā e whā, ā, i muri mai ka whakahokia ki ngā whare herehere whakamātautau mō ētahi atu rā e rua.

Pikitia 2: He kōhao kei te āraia e ngā OFC i te wā whakamātautau.

I arotakengia ngā hoahoa OFC

E iwa ngā hoahoa OFC rerekē i arotakengia mō te ātete ki ngā kiore. Ko ēnei hoahoa katoa he wāhanga o te rōpū hoahoa e kapi ana i te wāhanga nui rawa atu o te mākete OFC. Ka taea te wehewehe i ngā OFC ki ngā wāhanga e rua:

1. Ngā hoahoa OFC paerewa e whakamahi ana i te miro aramid, i te karāhe-E rānei (me te whakakī, me te kore rānei) hei rauemi whakapakari i raro i te uhi o waho o te PE (Pikitia 3a ki te 3d).

2. Ngā hoahoa OFC motuhake hei ātete i ngā whakaekenga a ngā kiore, hei tauira, ngā hanganga paparua, ngā hanganga rānei me te PA12, te maitai kowakawaka rānei (Pikitia 3e ki te 3i).

3. Ngā hua me te kōrero

I muri i ngā wā whakamātautau e rua, e rua ngā rā o ia wā, i tirohia te kino i puta mai i ngā whakaekenga a ngā kiore. I roto i ngā Pikitia 4a ki te 4i ka kite koe i ngā pikitia e rua o ia hoahoa taura i whakamatautauria; ko te pikitia o runga e whakaatu ana i te mea iti rawa te kino, ā, ko te pikitia o raro e whakaatu ana i te OFC tino kino. Ko ngā hua o te tirotiro whānui o ngā taura e whakaatu mārama ana i ngā rerekētanga o te kino i waenga i ngā hoahoa OFC e iwa. Engari, e kitea ana i roto i ngā pikitia, ko ngā OFC katoa - haunga te hoahoa maitai kowakawaka/aramid - kua pakaru i roto i te āhua e whakaarohia ana ka pāngia ngā āhuatanga tuku roa. Ka pā anō hoki tēnei ki ngā hoahoa OFC PE/karāhe-E kua whakakīia/rīpene ārai-wai (Pikitia 4d) me ngā whenu PE/karāhe-E kua whakakīia/PE/aramid (Pikitia 4h), ahakoa he iti ake te kino o ēnei hoahoa. Heoi, i roto i te mahi, ka pā ki ngā kiore kore-whare, ka uru pea ki ngā whakaeke kaha ake me te pumau mena ka mau te kiore. Nō reira, i runga i ngā hua o te whakamātautau TNO, ko te whakatau me kī ko te hoahoa maitai kowakawaka/aramid anake he ātete tino ki ngā kiore o ngā hoahoa kua whakamatautauria.

Ka taea hoki te whakapai ake i te ātete kiore o te OFC mā te whakamahi i ngā uhi o waho i hangaia mai i ngā polyamide amorphous, polyamide copolymers rānei, he tino pakeke te Shore D. Nō reira, ka tūtohu mātou ki ngā kaihoahoa taura kia whakapai ake i te ātete kiore o ngā OFC mā te whakamahi i te maitai kowakawaka (hei tauira, Zetabon) me ngā uhi rānei i hangaia mai i ngā polyamide amorphous, polyamide copolymers rānei (hei tauira, Grilamid). Ko te whakamahinga o te maitai kowakawaka te mea pai rawa atu.

He mea whakamere te whakaaro ko te whānui o te taura ka pā ki te ātete kiore o te OFC - arā, mai i tētahi whānui taura ki mua ka puta he awe pai ki te ātete kiore - ā, tera pea ka whai hua ngā rangahau atu anō mā ngā kaihoahoa taura.

Pikitia 4a: Te hoahoa taura PE/aramid i muri i te whakamātautau; te whānui 13.5 mm.

Pikitia 4b: He hoahoa taura karāhe-E kua whakakīia ki te PE/whakakīia i muri i te whakamātautau; he whānui 11.8 mm.

Pikitia 4c: Te hoahoa taura PE/E-karaehe i muri i te whakamātautau; te whānui 9.5 mm.

Pikitia 4d: He hoahoa taura rīpene PE/karaehe-E kua whakakīia ki te wai/ārai-wai i muri i te whakamātautau; he whānui 15.5 mm.

Pikitia 4e: He hoahoa taura PE/E-glass/PE/aramid kua whakakīia ki te wai PE/i muri i te whakamātautau; he whānui 8.8 mm.

Pikitia 4f: Te hoahoa taura PE/aramid/PE/aramid i muri i te whakamātautau; te whānui 21 mm.

Pikitia 4g: Te hoahoa taura PE/PA12/aramid i muri i te whakamātautau; te whānui 8.5 mm.

Pikitia 4h: Te hoahoa taura PE/aho karāhe-E kua whakakīia ki te wai/taura PE/aramid i muri i te whakamātautau; te whānui 15.7 mm

Pikitia 4i: He hoahoa taura PE/rino kōpikopiko/PE/aramid i muri i te whakamātautau; he whānui 14.7 mm.

4. Whakamutunga

I runga i ngā hua o ngā whakamātautau, kua whakatau a TNO, o ngā hoahoa OFC i whakamatautauria, ko te hoahoa maitai/aramid kōpiko anake te ātete tino ki ngā kiore. Ko ētahi atu hoahoa katoa (i whakapakaritia ki te karāhe-E me te kore rānei he whakakī - aramid rānei, me te hipoki PA12 rānei) kāore i tino ātete ki ngā whakaekenga a ngā kiore. E whakaatu mārama ana te rangahau mēnā e hiahiatia ana te ātete ki ngā kiore, me aro nui ki te hoahoa taura.
