Direct Roving Tex: Kusankha 2400, 4800 kapena 9600 kuti Pultrusion ndi Filament Winding zigwire ntchito

Mzere wa pultrusion womwe sumayenda bwino nthawi zambiri umakhala ndi vuto la tex, osati vuto la resin. Mbiriyo imatuluka ndi mabala ouma m'makona mukangowonjezera liwiro. Kapena kuchuluka kwa galasi kumakhala pansi pa zomwe chithunzicho chikufuna, ndipo kutentha kulikonse sikutseka mpata. Kapena malo aliwonse pa creel amakhalapo ndipo gawolo lilibe ulusi. Palibe chilichonse mwa izi chomwe chimawoneka ngati cholakwika cha datasheet, chifukwa palibe cholakwika pa datasheet. Amaonekera chifukwa tex idasankhidwa kuchokera pa kabukhu m'malo mwa mzere.

Bukuli limagwira ntchito posankha pakati pa 2400, 4800 ndi 9600 tex momwe mainjiniya amakwaniritsira: kuchuluka kwa manambala, chifukwa chake ma rotaving awiri okhala ndi tex imodzi sasinthasintha, kuchuluka kwa malekezero omwe mukufuna pa mbiri yanu, ndi mtengo wa zomwe mungatenge pa sitepe iliyonse.

Zimene tex imayesa kwenikweni (ndi nambala ya yield kumbuyo kwake)

Tex ndi yofanana ndi mzere: magalamu pa mamita 1,000. Tex roving ya 2400 imalemera 2.4 g pa mita iliyonse yomwe mumakoka; Tex ya 4800 imalemera 4.8 g; Tex ya 9600 imalemera 9.6 g. Ndi tanthauzo lonselo, ndipo ndiloyenera kufotokozedwa momveka bwino chifukwa tex imagwiritsidwa ntchito ngati chidule cha "kukhuthala" mwanjira yomwe imabisa zinthu ziwiri zomwe sizikufotokoza: kukula kwa ulusi mkati mwa chingwe, ndi mphamvu ya laminate yomwe mudzamanga kuchokera pamenepo.

Ngati zojambula zanu kapena dipatimenti yanu yogulira zinthu ikugwira ntchito m'mayunitsi aku US, mfundo zomwezo zimawoneka ngati kuchuluka kwa mayadi pa paundi, zomwe zimasonyeza katundu womwewo kuchokera mbali ina:

Mu mzere umodzi:yd/lb = 496,055 ÷ tex.

zovala zamkati	g/m	≈ yd/lb
1200	1.2	413
2400	2.4	207
4800	4.8	103
9600	9.6	52

Kusinthaku ndi masamu, osati kuyerekezera khalidwe la zinthu: 1 lb = 453.592 g ndi 1 yd = 0.9144 m, ndipo chokhazikikacho chimatuluka mu mfundo ziwirizi. N'kofunika chifukwa wogulitsa waku US akunena "206 yield" ndi pepala la datasheet lolemba "2400 tex" akufotokoza kuyendayenda komweko m'malemba awiri. Sinthani musanayerekeze, ndipo musaike chithunzi cha tex ndi chithunzi cha yield patebulo lomwelo popanda kulemba kuti ndi gawo liti.

Nsalu yofanana, chingwe chosiyana

Ogulitsa awiri akhoza kutchula 4800 tex koma amatumizabe zingwe zomwe zimachita zinthu mosiyana, chifukwa tex ndi chinthu chomwe chimachokera pa zisankho ziwiri zodziyimira pawokha: kuchuluka kwa ulusi womwe umanyamula, komanso kuchuluka kwa ulusi uliwonse.

Ulusi umodzi wa E-glass pa 17 µm umanyamula pafupifupi 0.58 tex; pa 24 µm, pafupifupi 1.15 tex, pa kachulukidwe ka galasi ka 2.55 g/cm³. Mukayesa masamu amenewo, chinthu chothandiza chimawonekera: chidebe cha mabowo 4,000 chokokedwa pa 17 µm chomwe chimagwera pafupi ndi 2,315 tex, pomwe chidebe cha mabowo 2,000 pa 24 µm chomwe chimagwera pafupi ndi 2,307 tex. Ulusi womwewo, theka la kuchuluka kwa mabowo, ulusi ndi wokulirapo pafupifupi 40% m'mimba mwake.

Zingwe ziwirizi sizili zofanana pansi pa mtsinje. Mtolo wa ulusi wambiri wopyapyala umapereka malo ambiri pamwamba pa utomoni ndipo umafalikira kukhala mzere wosalala, womwe umathandiza kunyowetsa ndikuthandizira kudzaza dzenje lalikulu, lopyapyala. Mtolo wa ulusi wochepa, wokhuthala umatuluka ndi kulowetsa madzi mosiyana, umakana kutseguka pakhomo lolowera, ndipo umasandulika mphamvu yake kukhala laminate mosiyana. Palibe chabwino kuposa izi m'chidule; ndi zida zosiyana.

Zimene izi zikutanthauza ndi zazing'ono komanso zotsika mtengo: funsani kukula kwa ulusi ndi kuchuluka kwa mabowo a bushing pamodzi ndi tex. Ogulitsa amafalitsa tex ndi m'mimba mwake ngati mizati yosiyana pachifukwa ichi, ndipo ndiyo njira yachangu yodziwira ngati 4800 yotsika mtengo ndi reinforcement yomweyo kapena nambala yomweyo.

Kuchuluka kwa kulemera: kuyambira pa mbiri mpaka kumapeto

Iyi ndi njira yowerengera yomwe imasintha chithunzi kukhala mawonekedwe a creel. Masitepe atatu, ndipo malingaliro ndi ofunika monga momwe masamu amagwirira ntchito.

Gawo 1 - kulemera kwa galasi pa mita imodzi.Tengani dera lopingasa mu cm², chulukitsani ndi 100 kuti mupeze voliyumu ya mita imodzi ya mbiri, chulukitsani ndi gawo la voliyumu ya ulusi womwe mukufuna, kenako ndi kuchuluka kwa galasi. Pa kuchuluka, 2.55 g/cm³ ndiye mtengo womwe wagwiritsidwa ntchito pano.

Gawo 2 - limatha.Gawani kulemera kwa galasi pa mita imodzi ndi kulemera komwe kumaperekedwa kumapeto kwa mita imodzi, komwe ndi tex ÷ 1,000.

Gawo 3 - zungulirani ndikuwunikanso.Mapeto ndi manambala okwana. Sonkhanitsani, kenako werengani kuchuluka kwa ulusi womwe mukufuna kumanga, chifukwa ndi mbiri yomwe mudzatumize.

Malingaliro, omwe adanenedwa kamodzi kuti mulowe m'malo mwa anu: mphamvu zonse zolimbikitsira zimayendayenda (palibe mphasa, chophimba kapena chodzaza mu gawolo), cholinga cha Vf ndi gawo la voliyumu m'malo mwa gawo lolemera, ndipo kuchotsedwa kwa die ndi resin bleed-back zimanyalanyazidwa. Sinthani chilichonse mwa izo ndipo manambala amasuntha.

Chitsanzo chogwira ntchito: mbiri yathyathyathya ya 100 mm × 6 mm pa Vf ya 0.60.

Malo = 6.00 cm², kotero mita imodzi ya mbiri ili ndi 600 cm³ ya zinthu

Kuchuluka kwa galasi = 600 × 0.60 = 360 cm³

Kulemera kwa galasi = 360 × 2.55 =918 g/m

zovala zamkati	g/m pa mapeto	zofunikira (zoyenera)	zimatha kuyitanitsa	g/m yoperekedwa	Vf yomangidwadi
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

Zosankha zonse zitatu za tex zafika pa chandamale mkati mwa kuzungulira. Ichi ndichifukwa chake: pagawo lino la kuwerengera tex ikuwoneka ngati chisankho chaulere. Kusiyana komwe kumatsimikiza kuti sikupezeka patebulo ili.

Zimene mumapeza ndi zomwe mumalipira mukakwera sitepe

Malekezero mazana atatu ndi makumi asanu ndi atatu ndi atatu amakhala 192, kenako 96. Chiŵerengero chimodzi chimenecho chimayendetsa maakaunti anayi osiyana, ndipo onse sapita mbali imodzi.

Malo ozungulira ndi nthawi yokonza ulusi.Mtengo wa Creel ndi pa malo aliwonse, ndipo ntchito yoika ulusi ndi yofanana. Kudula malekezero ndi theka pakati pa onse awiri. Pa mzere pomwe kutalika kwa creel ndiye choletsa chomangirira - chomwe ndi mizere yambiri yozungulira - nthawi zambiri ichi ndiye chifukwa chenicheni chokwerera sitepe, ndipo sichikugwirizana ndi zinthuzo.

Kusintha kwa phukusi ndi ma splices.Theka la malekezero limatanthauza theka la ma phukusi, kotero theka la ma doff ndi theka la ma splices pa shift iliyonse. Pa kuthamanga kosalekeza, kusokoneza kochepa kumakhala kofunikira kuposa chithunzi chabwino kwambiri chonyowa, chifukwa splice iliyonse ndi malo omwe china chake chingayende bwino.

Kunyowa.Apa ndi pomwe chiganizo cha katalogu chimafunikira chiyeneretso. Tex yapamwamba imakweza kuchuluka kwa ulusi kumapeto, ndipo tsamba la malonda likunena mwachindunji: nambala yayikulu ya tex imatanthauza ulusi wokhuthala, womwe ungagwiritsidwe ntchito kuwonjezera kuchuluka kwa ulusi ndikufulumizitsa kupanga. Izi ndi zoona, ndipo ndi mawu okhudza kuchuluka kwa ulusi kumapeto. Si lonjezo kuti kulowetsedwa kwanu kudzapitirira.

Nthawi yokhala m'bafa ndi kutalika kwa bafa komwe kumagawidwa ndi liwiro la mzere. Bafa la 0.6 m lomwe likuyenda pa 0.3 m/min limapereka chingwe chilichonse mphindi ziwiri mu utomoni; pa 0.6 m/min limapereka mphindi imodzi; pa 1.2 m/min, masekondi makumi atatu. Mtolo wokhuthala uli ndi zigawo zambiri za utomoni kuti utomoni ulowe, kotero nthawi yomweyo yokhalamo imagula kulowa kochepa. Kwezani liwiro la tex ndi mzere pamodzi - zomwe ndi zomwe mkangano wa throughput umalimbikitsa - ndipo zotsatira ziwirizi zimaphatikizana ndi wet-out.

Kusasinthika kwa zinthu za ulusi.Malekezero amodzi a 2400 tex amasuntha Vf ndi ma points pafupifupi 0.16 peresenti pa mbiri iyi. Malekezero amodzi a 4800 tex amasuntha 0.31; malekezero amodzi a 9600 tex, 0.63. Ngati mfundo zanu ndi 60 ± 1%, zonse zitatuzi zimagwira ntchito. Ngati mukudula mkati mwa zenera la mfundo imodzi — 62% mpaka 63%, kapena kufananiza kuponi ya kasitomala — 2400 tex imakupatsani masitepe pafupifupi asanu ndi limodzi kudutsa, 9600 tex ndi imodzi yokha.

Mukaphatikiza pamodzi, kapangidwe kake ndi kofanana: makoma owonda, magawo ang'onoang'ono ndi kulekerera kwa ulusi wolimba kumakukakamizani kupita ku tex yopyapyala, komwe malekezero owonjezera amagula resolution komanso kufalikira. Magawo okhuthala, ma run ataliatali ndi mizere yochepa imakukakamizani kupita ku tex yopyapyala, komwe malekezero ochepa amagula kuphweka. Mizere yochepa kwambiri imachepetsedwa ndi zonse zinayi nthawi imodzi, ndichifukwa chake yankho limasiyana pakati pa zomera ziwiri zomwe zikuyenda ndi mbiri yomweyo.

Kuzungulira kwa pultrusion ndi filament: tex yomweyo, denga ziwiri

Tex yomweyi imachita mosiyana m'njira ziwirizi chifukwa choletsa malire si chofanana.

In kuphulika, denga ndiye khomo lolowera. Malekezero onse ayenera kufalikira mu mzere womwe umadzaza dzenje mofanana, popanda mipata komanso popanda kuphatikizika. Malekezero ocheperako, opapatiza amafalikira mosavuta ndipo amadzaza gawo lalikulu, losaya bwino; malekezero ochepa, okhuthala amakhala olimba, amakana kutseguka, ndipo amatha kusiya makona opanda chakudya. Chifukwa chake tex yothandiza imakhazikitsidwa ndi kuchuluka kwa malekezero omwe creel yanu imagwirira ntchito komanso momwe kufalikira kwanu kusanachitike kufa kumagwirira ntchito - osati ndi zomwe deta ikupereka.

In kupotoza kwa ulusi, denga ndi la bandwidth ndi mphamvu. Pakutha kofanana, malekezero 48 a 2400 tex ndi malekezero 12 a 9600 tex amapereka mphamvu yofanana pa ola limodzi. Malekezero khumi ndi awiri amatanthauza njira yaifupi yokakamiza komanso malangizo ochepa, omwe ndi osavuta kuwongolera komanso osavuta kuwabwereza. Koma phukusi lililonse mwa khumi ndi awiriwa tsopano limanyamula kuyenda kowirikiza kanayi kuposa mphamvu, kotero chomangira chimodzi, phukusi limodzi loipa kapena kukwera kwa mphamvu kumodzi kumawonekera ngati vuto la band pamalo okulirapo. Kuzungulira kumakhudzanso kukula kwa band pa pass iliyonse, komwe kumasintha ndi tex: kuyenda kolimba kumaphimba m'lifupi kwambiri mu travel imodzi, zomwe zimasintha kuchuluka kwa ma pass omwe amatseka wosanjikiza.

Kuyenda mozungulira bwino kwambiri pa malekezero 383 kudzera mu die ya pultrusion kungakhale chisankho cholakwika pa malekezero 12 pa mandrel. Nambala yomweyo, denga losiyana.

Nambala yogwiritsira ntchito yomwe imakula kukula kwa creel yanu

Musanapereke chilolezo chanu chogwiritsa ntchito tex, yang'anani zomwe creel yanu ikupereka:

Masamu ndi mzere umodzi:kg/h = mapeto × (tex ÷ 1000) × liwiro la mzere (m/min) × 0.06.

Pa 25 m/mphindi, kupereka 172.8 kg/h kumatenga malekezero 48 a 2400 tex, malekezero 24 a 4800 tex, kapena malekezero 12 a 9600 tex.

zovala zamkati	imatha pa 172.8 kg/h pa 25 m/min	mapeto a 345.6 kg/h pa 25 m/min
2400	48	96
4800	24	48
9600	12	24

Iyi ndi nambala yomwe imayika kukula kwa creel, kulemera kwa phukusi ndi nthawi yodumpha. Siikuuzani ngati mzerewo udzanyowa - ndiko kuwerengera nthawi yogona pamwambapa - ndipo siikuuzani ngati mbiriyo idzadzaza. Gwiritsani ntchito kukula kwa creel, kenako gwiritsani ntchito zina ziwiri kuti muwone ngati creel yomwe mwayesa ikhoza kugwira ntchito.
