Direct Roving Tex: Te whiriwhiri i te 2400, 4800, 9600 rānei mō te Pultrusion me te Filament Winding

Ko te aho pultrusion kāore e tino rere ma, he maha ngā wā ka raru ia i te tex, ehara i te raru i te kapia. Ka puta mai ngā wāhi maroke i ngā kokonga o te kōtaha ina pēhi koe i te tere. Kei raro iho rānei te ihirangi karāhe i te mea e tonoa ana e te tuhi, ā, kāore he nui o te pāmahana o te mate e kati ana i te āputa. Kei te nohoia rānei ngā tūranga katoa o te creel, ā, he iti tonu te muka o te wāhanga. Kāore tētahi o ēnei e puta mai hei hapa pepa raraunga, nā te mea kāore he mea he i runga i te pepa raraunga. Ka puta mai nā te mea i whiriwhiria te tex mai i tētahi rārangi pukapuka, kaua i te rārangi.

Ka whakamāramahia e tēnei aratohu te kōwhiringa i waenga i te 2400, 4800 me te 9600 te tikanga e tutuki ai i te hiahia o te kaihangarau tukanga: he aha te ine a te tau, he aha ngā take e kore ai e taea te whakawhiti i ngā porowhita e rua me te tau kotahi, e hia ngā pito e hiahiatia ana mō tētahi kōtaha, me te utu mō ia taahiraa ake.

He aha te ine a te tex (me te tau hua kei muri)

Ko te Tex he mātotoru rārangi: karamu mō ia 1,000 mita. Ko te taumaha o te 2400 tex roving he 2.4 karamu mō ia mita ka tōia e koe; ko te taumaha o te 4800 tex he 4.8 karamu; ko te taumaha o te 9600 tex he 9.6 karamu. Koinei te whakamāramatanga katoa, ā, he mea tika kia kī mārama nā te mea ka whakamahia te tex hei whakarāpopototanga mō te "matotoru" i roto i te huarahi e huna ana i ngā mea e rua kāore e whakaahuahia: te whānui o te miro i roto i te miro, me te kaha o te laminate ka hangaia e koe mai i a ia.

Mena ka whakamahia ō tuhi, tō tari hoko rānei i roto i ngā waeine US, ka puta te whakatakotoranga ōrite hei hua i roto i ngā iāri mō ia pauna, e whakaatu ana i te āhuatanga ōrite mai i te taha kē:

I te rārangi kotahi:iāri/pauna = 496,055 ÷ tekiona.

tex	karamu/mita	≈ iāri/pauna
1200	1.2	413
2400	2.4	207
4800	4.8	103
9600	9.6	52

He tātaitanga te tahuritanga, ehara i te whakatau tata o te whanonga rauemi: 1 pauna = 453.592 karamu me te 1 iari = 0.9144 m, ā, ka taka te pūmau i waho o aua meka e rua. He mea nui tēnei nā te mea kei te whakaahuahia e te kaituku o Amerika te "206 hua" me te pepa raraunga mira e kī ana "2400 tex" te haereere kotahi i roto i ngā tohu e rua. Tahurihia i mua i te whakataurite, kaua rawa e whakauru i te ahua tex me te ahua hua ki te ripanga kotahi me te kore e tapaina ko tēhea pou.

Kotahi te kuputuhi, rerekē te aho

Ka taea e ngā kaiwhakarato e rua te whakahua i te 4800 tex, ā, ka tukuna tonutia ngā miro e rerekē ana te whanonga, nā te mea ko te tex te hua o ngā whakataunga motuhake e rua: te maha o ngā miro kei roto i te pū, me te matotoru o ia miro.

Kotahi te miro karāhe-E i te 17 µm e mau ana i te 0.58 tex; i te 24 µm, tata ki te 1.15 tex, i te mātotoru karāhe e whakaarohia ana he 2.55 g/cm³. Whakahaerehia taua tātaitanga, ā, ka puta he mea whai hua: ka tau te pūwero 4,000-pū i te 17 µm ki te tata ki te 2,315 tex, ko te pūwero 2,000-pū i te 24 µm ki te tata ki te 2,307 tex. Ko te tex anō, ko te haurua o te maha o ngā pūwero, he 40% te whānui o ngā miro.

Kāore ngā miro e rua i te ōrite ki raro iho. He nui ake te mata o te kapia e puta mai ana i te paihere o ngā miro angiangi maha, ā, ka horapa hei whitiki papatahi, ka āwhina i te whakamakuku me te whakakī i te kōhao whānui, angiangi. He rerekē te rere me te whakapūmau o te paihere o ngā miro iti ake, he matotoru, ā, he rerekē te ātete ki te whakatuwheratanga i te tomokanga o te mate, ā, he rerekē te whakaputa i tōna ake kaha ki roto i te raima. Kāore tetahi o ēnei i te pai ake i te tirohanga whānui; he rerekē ngā taputapu.

He iti, he iti hoki te utu o te mahi e tohuhia ana e tēnei: pātaihia te whānui o te miro me te maha o ngā kōhao o te pūwero i te taha o te tex. Mō tēnei take tonu, ka whakaputahia e ngā kaiwhakarato te tex me te whānui hei pou motuhake, ā, koinei te huarahi tere ki te kimi mēnā he rite tonu te whakakaha o tētahi 4800 iti ake te utu, he rite tonu rānei te tau.

Te taurite papatipu: mai i te kōtaha ki ngā pito

Koinei te tātaitanga e huri ai te tuhi hei tahora anga. E toru ngā taahiraa, ā, he rite te hiranga o ngā whakapae ki te pāngarau.

Hipanga 1 — papatipu karāhe mō ia mita.Tangohia te horahanga whakawhiti i roto i te cm², whakareatia ki te 100 kia whiwhi ai i te rōrahi o te kotahi mita o te kōtaha, whakareatia ki te wāhanga rōrahi muka e hiahiatia ana, kātahi ki te mātotoru karāhe. Mō te mātotoru, ko te 2.55 g/cm³ te uara e whakamahia ana i konei.

Hipanga 2 — ka mutu.Wehea te papatipu karāhe mō ia mita ki te papatipu ka tukuna e tetahi pito mō ia mita, arā, tex ÷ 1,000.

Hipanga 3 — hurihia, tirohia anō.He tauoti ngā pito. Whakaawhiwhia, kātahi ka tatau i te nui o te muka ka hangaia e koe, nā te mea koinā te kōtaha ka tukuna e koe.

Ngā whakaaro, me kī kotahi kia taea ai e koe te whakakapi i tāu ake: he huri noa ngā whakakaha katoa (kāore he whāriki, he ārai, he whakakī rānei i te wāhanga), ko te Vf whāinga he wāhanga rōrahi kaua ki te wāhanga taumaha, ā, ka kore e arohia te ātea o te mate me te whakaheke toto kapia. Hurihia tētahi o ēnā, ā, ka neke ngā tau.

Tauira i mahi: he kōtaha papatahi 100 mm × 6 mm i te Vf ūnga o te 0.60.

Horahanga = 6.00 cm², nō reira kei roto i te mita kotahi o te kōtaha he 600 cm³ o te rauemi

Te rōrahi o te karāhe = 600 × 0.60 = 360 cm³

Papatipu karāhe = 360 × 2.55 =918 karamu/mita

tex	g/m ia pito	ngā mutunga e hiahiatia ana (tika tonu)	mutu ki te ota	g/m i tukuna	I hangaia e Vf
2400	2.4	382.5	383	919.2	0.601
4800	4.8	191.3	192	921.6	0.602
9600	9.6	95.6	96	921.6	0.602

I tutuki katoa ngā kōwhiringa tex e toru ki te whāinga i roto i te whakaawhiwhinga. Koinei te kaupapa: i tēnei wāhanga o te tatau, he rite te tex ki tētahi kōwhiringa kore utu. Kāore i roto i tēnei ripanga ngā rerekētanga e whakatau ana i tēnei.

Ngā mea ka riro i a koe, me ngā mea ka utua e koe ina piki ake koe i tētahi taahiraa

E toru rau waru tekau mā toru ngā pito ka huri hei 192, kātahi ka 96. Mā taua ōwehenga kotahi e ārahi ngā pūkete motuhake e whā, ā, kāore e neke katoa i te huarahi kotahi.

Ngā tūranga tīwiri me te wā miro.Ko te utu mō te miro he mea whakarite mō ia tūranga, me te mahi hoki mō te miro. Mā te haurua o ngā pito ka haurua ngā mea e rua. Mō tētahi rārangi ko te roa o te miro te here here — arā, ko te nuinga o ngā rārangi miro — koinei te tino take e piki ake ai i tētahi taahiraa, ā, kāore he pānga ki te rauemi.

Ngā whakarerekētanga mōkihi me ngā hononga.Ko te haurua o ngā pito ko te haurua o ngā mōkihi, nō reira ko te haurua o ngā tapahi me te haurua o ngā hononga mō ia nekehanga. I runga i te oma tonu, he nui ake te uara o ngā whakararuraru iti iho i te ahua pai ake o te makuku, nā te mea ko ia hononga he wāhi ka hē ai tetahi mea.

Makuku-waho.Koinei te wāhi e hiahiatia ana he tohu mō te kereme o te putumōhio. Mā te teitei ake o te tex ka piki ake te tere o te muka mō ia pito, ā, e kī tika ana te whārangi hua: ko te tau tex teitei ake he aho matotoru ake, ka taea te whakamahi hei whakanui ake i te nui o te muka me te tere ake o te whakaputa. He pono tēnā, ā, he kōrero mō te tere o te muka mō ia pito. Ehara i te mea he oati ka mau tonu tō whakatōnga.

Ko te wā noho i roto i te kaukau he roa kaukau wehea ki te tere o te aho. Mā te kaukau 0.6 m e rere ana i te 0.3 m/min ka rua meneti te roa o te wā e noho ana ia miro i roto i te kapia; mā te 0.6 m/min ka kotahi meneti; mā te 1.2 m/min ka toru tekau hēkona. He maha ake ngā paparanga miro o te paihere matotoru hei whakauru mā te kapia, nō reira, mā te wā noho kotahi ka iti ake te whakauru. Whakanuia te tere o te aho me te aho ngātahi — koinei tonu te mea e akiakihia ana e te tautohe whakaputanga — ā, ka honoa ngā pānga e rua ki te putanga mākū.

Te taumira i te ihirangi muka.Kotahi te pito o te 2400 tex e neke ana i te Vf mā te 0.16 ōrau pea i runga i tēnei kōtaha. Kotahi te pito o te 4800 tex e neke ana i te 0.31; tētahi pito o te 9600 tex, 0.63. Mena ko tō whakatakotoranga he 60 ± 1%, ka taea te whakamahi i ngā mea e toru. Mena kei te kutikuti koe i roto i te matapihi kotahi-ira — 62% ki te 63%, e taurite ana rānei ki te tīkitipati a te kiritaki — ka hoatu e te 2400 tex ki a koe te ono hikoinga puta noa, 9600 tex he kotahi noa iho.

Ki te whakakotahihia, he ōrite te tauira: ko ngā pakitara angiangi, ko ngā wāhanga iti me ngā ātete ki te ihirangi muka ka panaia koe ki te papanga angiangi ake, ko ngā pito tāpiri ka hoko i te taumira me te horapa ōrite. Ko ngā wāhanga matotoru, ko ngā oma roa me ngā rārangi here-pūnga ka panaia koe ki te papanga matotoru ake, ko ngā pito iti ka hoko i te māmā. He iti noa ngā rārangi ka herea e ngā mea e whā i te wā kotahi, koia te take he rerekē te whakautu i waenga i ngā tipu e rua e whakahaere ana i te kōtaha kotahi.

Te whakakorikori me te takai miro: tex kotahi, e rua ngā tuanui

He rerekē te whanonga o taua tuhinga kotahi i roto i ngā tukanga e rua nā te mea he rerekē te herenga whakawhāiti.

In te pupuhi, ko te tuanui te tomokanga o te mate. Me horahia ia pito ki roto i tētahi whitiki e whakakī ana i te kōhao kia ōrite, kia kore he āputa, kia kore hoki e taupatupatu. Mēnā he nui ake, ka tere ake te hora o ngā pito angiangi, ā, ka pai ake te whakakī i tētahi wāhanga whānui, pāpaku; he iti ake, he matotoru ake ngā pito he pakari ake, he ātete ki te whakatuwheratanga, ā, ka waiho pea ngā kokonga kia kore e taea te whakatuwhera. Nō reira, ko te tikanga mahi ka whakatakotoria e te maha o ngā pito e mau ana tō kiri me te pai o te mahi a tō horahanga i mua i te mate - ehara i te mea e tukuna ana e te pepa raraunga.

In takai miro, ko te tuanui he whānui me te taumahatanga. Mēnā he ōrite te tere o te whakawhiti, e 48 ngā pito o te 2400 tex me te 12 ngā pito o te 9600 tex ka tukuna te taumaha ōrite mō ia hāora. Tekau mā rua ngā pito e tohu ana he poto ake te ara taumahatanga me te iti ake o ngā kaiārahi, he māmā ake te whakahaere me te miro anō. Engari e whā ngā wā o te rere taumahatanga o ia mōkihi tekau mā rua, nō reira, kotahi te raru, kotahi te mōkihi kino, kotahi rānei te pikinga taumahatanga ka puta hei hapa roopu i runga i te rohe whānui. E aro ana hoki te takai ki te whānui o te roopu mō ia haerenga, e rerekē ana me te tex: he whānui ake te whānui o te haereere matotoru i roto i te kotahi haerenga, e whakarerekē ana i te maha o ngā haerenga e kati ana i tētahi paparanga.

Ko te huri haere e pai ana i ngā pito 383 mā roto i te mati pultrusion he kōwhiringa hē pea i ngā pito 12 o te mandrel. He rite tonu te tau, he rerekē te tuanui.

Ko te tau whakaputanga e rahi ana i tō cree

I mua i tō whakaae ki tētahi ratonga tex, tirohia ngā mea e tika ana kia tukuna e tō creel:

Kotahi te rārangi o te taunga:kg/h = ngā pito × (tex ÷ 1000) × tere raina (m/min) × 0.06.

I te 25 m/min, ko te tuku i te 172.8 kg/h e hiahiatia ana he 48 pito o te 2400 tex, he 24 pito o te 4800 tex, he 12 rānei pito o te 9600 tex.

tex	ka mutu mō te 172.8 kg/h i te 25 m/min	ka mutu mō te 345.6 kg/h i te 25 m/min
2400	48	96
4800	24	48
9600	12	24

Koinei te tau e whakatakoto ana i te rahi o te anga, te taumaha o te mōkihi me te wā tango. Kāore e kī ana mēnā ka mākū te aho — koinei te tātaitanga wā noho i runga ake nei — ā, kāore e kī ana mēnā ka kī te kōtaha. Whakamahia hei rahi i te anga, kātahi ka whakamahia ngā mea e rua hei tirotiro mēnā ka taea te whakahaere i te anga i whakaritea e koe.

Ngā Pātai Auau

Me hoko noa rānei e au te tex tino matotoru hei tapahi i ngā pito o te makawe?

Ka taea e koe, ā, i runga i te rārangi here-kiri he maha ngā wā ka tika. Tirohia ngā mea e rua i te tuatahi: te roa o te noho ka tukuna e tō kaukau i te tere e hiahiatia ana e koe, me te mea he tino matotoru rawa tetahi pito o taua kuputuhi mō tō manawanui ki te ihirangi muka. Ki te paahitia e rua, ka toa te kuputuhi matotoru i runga i te māmā.

E rua ngā kaiwhakarato e whakahua ana i te ture kotahi — ka taea te whakawhiti?

Kāore rawa. Pātaihia te whānui o te miro, te maha o ngā kōhao o te pūwero me te pūnaha rahi. Ka rerekē te makuku o te miro kotahi me te hanganga miro rerekē, ā, e kore e rite te kaha ki te whakapiripiri.

Kei waenganui i te 2400 me te 9600 te 4800 tex?

I roto i te papatipu, āe: he rite tonu te rua me te haurua. I roto i ngā tikanga tukanga, kāore. Ka haurua ngā pito me te kore e haurua te maha o ngā mahi whakatikatika, ā, ka rua te rere o te papatipu mō ia kete kaua e whakawhā. Kāore ngā taurite i te rārangi, koia te take he maha ngā wā ko te kōwhiringa waenga te mea e uru ana ki te rārangi me te kōwiri pumau me te manawanui piri.

Kōwhiria te kuputuhi ka taea e tō raina te pupuri

He whakatau rārangi a Tex e mau ana i ngā kākahu o te pepa raraunga. Tīmata mai i te wāhanga me te ihirangi muka ūnga, tahurihia ki te karamu mō ia mita, wehea mā te tex hei tiki i ngā pito, kātahi ka tirohia ngā mea e toru kāore e taea e te rarangi pukapuka te kī atu ki a koe: mēnā he wāhi kei te anga, mēnā he wā kei te kaukau, ā, mēnā he pai te whakatikatika i tētahi pito.Tirotirohia ngā hua whakapakari muka karāhe a Ruifiberkia kite i te whānuitanga whakakaha i te taha o tēnei rārangi kopikopiko, me te pānui i tete hurihuri tika mō te pultrusion me te takai mirowhārangi i mua i tō tukunga i tētahi RFQ e whakaingoa ana i tō tukanga, wāhanga, ūnga Vf me te kapia — ka nui ake ngā mea ka tohua e koe, ka nui ake te whakautu ka hoki mai kua ōrite ki tō raina.
