Direct Roving Tex: Kusarudza 2400, 4800 kana 9600 yePultrusion neFilament Winding

Mutsetse we pultrusion usinganyatso shanda zvakanaka unowanzova nedambudziko re tex, kwete dambudziko re resin. Profile inobuda nemapenji akaoma pamakona kana uchango wedzera kumhanya. Kana kuti girazi riri pasi pezvinodiwa nedhirowa, uye hapana tembiricha ye die inovhara mukaha. Kana kuti nzvimbo yega yega pa creel inenge yakabatwa uye chikamu chacho chichiri kushomeka ne fiber. Hapana chimwe cheizvi chinoratidza kukanganisa kwe datasheet, nekuti hapana chakaipa pa datasheet. Zvinoonekwa nekuti tex yakasarudzwa kubva pane catalog pane kubva pamutsetse.

Gwaro iri rinoshanda kuburikidza nesarudzo iri pakati pe2400, 4800 ne9600 tex nenzira iyo mainjiniya wekugadzirisa anoizadzisa nayo: kuti nhamba yacho inoyera sei, nei mafambiro maviri ane tex imwe chete asingachinjiki, kuti magumo mangani anodiwa neprofile yakatarwa, uye kuti danho rega rega rinodhura zvakadii.

Chii chinoyerwa netex chaizvo (uye nhamba yekukohwa iri shure kwayo)

Tex ine huwandu hwakatsetseka: magiramu pa 1,000 metres. 2400 tex roving inorema 2.4 g pa mita yega yega yaunodhonza; 4800 tex inorema 4.8 g; 9600 tex inorema 9.6 g. Ndiyo tsananguro yese, uye zvakakodzera kutaura zvakajeka nekuti tex inoshandiswa sechidimbu che "ukobvu" nenzira inovanza zvinhu zviviri zvaisingatsananguri: dhayamita ye filament mukati me tambo, uye simba re laminate rauchavaka kubva mariri.

Kana madhirowa ako kana dhipatimendi rako rekutenga richishanda muUS units, zvirevo zvakafanana zvinoonekwa sehuwandu hwemayadhi papaundi, izvo zvinoratidza hunyanzvi hwakafanana kubva kune rimwe divi:

Mumutsara mumwe chete:yd/lb = 496,055 ÷ tex.

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

Kushandurwa uku kuri masvomhu, kwete kufungidzirwa kwemaitiro ezvinhu: 1 lb = 453.592 g uye 1 yd = 0.9144 m, uye chinoramba chiripo kubva muzvinhu zviviri izvi. Zvinokosha nekuti muparidzi wekuUS anotaura "206 yield" uye pepa redata remuchina rinoti "2400 tex" vari kutsanangura kufamba kwakafanana muzvinyorwa zviviri. Shandura usati waenzanisa, uye usamboisa tex figure ne yield figure mutafura imwe chete usina kunyora kuti koramu ipi ndeipi.

Tekisi imwe chete, tambo yakasiyana

Vatengesi vaviri vanogona kutaura 4800 tex asi vachitumira tambo dzinoita zvakasiyana, nekuti tex imhedzisiro yezvisarudzo zviviri zvakazvimiririra: kuti bhandi rinotakura shinda ngani, uye kuti shinda imwe neimwe yakakora sei.

Filament imwe yegirazi reE pa 17 µm ine huremu hunosvika 0.58 tex; pa 24 µm, inenge 1.15 tex, pa 2.55 g/cm³ yegirazi inofungidzirwa. Tarisa masvomhu iwayo wobva waona chinhu chinobatsira: bushing ine maburi 4,000 yakatorwa pa 17 µm yakawira pedyo ne 2,315 tex, ukuwo bushing ine maburi 2,000 pa 24 µm yakawira pedyo ne 2,307 tex. Tex imwecheteyo, hafu yehuwandu hwemaburi, maburi akakura ne 40% mudhayamita.

Tambo mbiri idzi hadzina kufanana nedzepasi. Boka remashinda akawanda akanaka rinopa nzvimbo yakakura kune resin uye rinopararira kuita band rakatsetseka, iro rinobatsira kunyorova uye rinobatsira kuzadza goko rakakura, rakatetepa. Boka remashinda mashoma, akakora anobuda mvura uye anonyudza zvakasiyana, anodzivirira kuvhurika pamusuwo wekufa, uye anoshandura simba rawo kuita laminate zvakasiyana. Hapana chimwe chazvo chiri nani muchidimbu; zvishandiso zvakasiyana.

Chiito ichi chinoreva chidiki uye chakachipa: bvunza dhayamita yefilament uye huwandu hwemaburi ebhandi pamwe chete netex. Vatengesi vanoburitsa tex nedhayamita semakoramu akasiyana nekuda kwechikonzero ichi, uye ndiyo nzira inokurumidza yekuona kana 4800 yakachipa iri reinforcement imwechete kana kuti ingori nhamba imwe chete.

Kuenzana kwehuwandu: kubva paprofile kusvika kumagumo

Uku ndiko kuverenga kunoshandura mufananidzo kuita creel layout. Matanho matatu, uye fungidziro dzacho dzinokosha sekuverenga.

Danho 1 - girazi rinorema pamita imwe neimwe.Tora nzvimbo yechikamu chepakati mu cm², wedzera ne 100 kuti uwane vhoriyamu yemita imwe yeprofile, wedzera nechikamu che fiber vhoriyamu chakatarwa, wobva wawedzera ne glass density. Pahuwandu hwehuwandu, 2.55 g/cm³ ndiyo kukosha kunoshandiswa pano.

Danho rechipiri - rinopera.Govanisa huremu hwegirazi pamita imwe neimwe nehuremu hunopihwa mugumo mumwe chete pamita imwe neimwe, inova tex ÷ 1,000.

Danho rechitatu - tenderera woongororazve.Magumo inhamba dzese. Dzokorora, wobva waverenga huwandu hwefiber hwauri kuzogadzira, nekuti ndiyo profile yauchazotumira.

Mafungiro, akambotaurwa kamwe chete kuti ugone kutsiva ako: zvese zvinosimbisa zviri kufamba-famba (hapana mat, veil kana filler muchikamu), chinangwa Vf chikamu chevhoriyamu pane chikamu chehuremu, uye die clearance neresin bleed-back hazvitariswe. Chinja chero cheizvozvo uye nhamba dzinofamba.

Muenzaniso wakashanda: chimiro chakati sandara che 100 mm × 6 mm pachinangwa che Vf che 0.60.

Nzvimbo = 6.00 cm², saka mita imwe yeprofile ine 600 cm³ yezvinhu

Vhoriyamu yegirazi = 600 × 0.60 = 360 cm³

Huremu hwegirazi = 360 × 2.55 =918 g/m

tex	g/m pamagumo ese	magumo anodiwa (chaiwo)	zvinopera nekuraira	g/m yatumirwa	Vf yakavakwa zvechokwadi
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

Sarudzo dzese nhatu dze tex dzakasvika pachinangwa mukati me rounding. Ndiyo pfungwa huru: padanho rino rekuverenga tex inoita sesarudzo yakasununguka. Misiyano inoita kuti isavepo mutafura iyi.

Zvaunowana uye zvaunobhadhara kana ukakwidza nhanho

Magumo mazana matatu nemakumi masere nematatu anova 192, obva ava 96. Chiyero chimwe chete ichocho chinotyaira maakaundi mana akasiyana, uye haafambi ese akananga divi rimwe chete.

Nzvimbo dzeCreel nenguva yekushongedza shinda.Mutengo weCreel unoenderana nenzvimbo, uye ndizvo zvakaitawo basa rekuibatanidza neshinda. Kugura magumo nehafu nehafu. Pamutsetse apo kureba kwecreel ndiko kunosunga - inova ndiyo mitsetse yakawanda ye pultrusion - ichi ndicho chikonzero chaicho chekukwira nhanho, uye hazvina chekuita nechinhu chacho.

Kuchinja mapakeji uye zvikamu.Hafu yemagumo inoreva hafu yemapakeji, saka hafu yemadoffs nehafu yemasplices pakuchinjana. Pakumhanya nguva dzose, kukanganiswa kushoma kunokosha kupfuura mufananidzo uri nani wet-out, nekuti splice yega yega inzvimbo iyo chimwe chinhu chinogona kutadza kufamba zvakanaka.

Kunyorova.Apa ndipo panoda chiziviso chekatalogu. Tex yakakwira inowedzera kuyerera kwefiber pamucheto wega wega, uye peji rechigadzirwa rinotaura zvakananga: nhamba yakakwira yetex inoreva tambo yakakora, iyo inogona kushandiswa kuwedzera huwandu hwefiber uye kukurumidzisa kugadzirwa. Izvozvo ndezvechokwadi, uye chirevo pamusoro pekubudirira pamucheto wega wega. Hazvisi vimbiso yekuti kuisirwa kwako kucharamba kuripo.

Nguva yekugara mubhavhu inoyera kureba kwebhavhu rakakamurwa nekumhanya kwemutsetse. Bhavhu re 0.6 m rinomhanya pa 0.3 m/min rinopa tambo yega yega maminitsi maviri muresin; pa 0.6 m/min rinopa miniti imwe; pa 1.2 m/min, masekondi makumi matatu. Bundle rakakura rine zvidimbu zvakawanda zvefilament kuti resin ipinde, saka nguva imwechete yekugara inotenga kupinda kushoma. Simudza tex nekumhanya kwemutsetse pamwe chete - izvo chaizvo zvinokurudzirwa nepfungwa ye throughput - uye mhedzisiro mbiri idzi dzinosangana nekubuda kwemvura.

Kugadziriswa kwehuwandu hwefiber.Mugumo mumwe chete we2400 tex unofambisa Vf neanenge 0.16 muzana yemapoinzi pane iyi profile. Mugumo mumwe chete we4800 tex unoifambisa 0.31; mugumo mumwe chete we9600 tex, 0.63. Kana zvaunoda zviri 60 ± 1%, zvese zvitatu zvinoshanda. Kana uri kuchekerera mukati mehwindo repoindi imwe chete — 62% kusvika 63%, kana kufananidza coupon yemutengi — 2400 tex inokupa matanho matanhatu pairi, 9600 tex isina kana rimwe chete.

Kana zvabatanidzwa, maitiro acho akafanana: madziro matete, zvikamu zvidiki uye zvinokwanisa kusimba fiber zvinokusundira kune tex yakapfava, uko magumo ekuwedzera anotenga resolution uye kunyange kupararira. Zvikamu zvakakora, marefu run uye mitsetse yakaganhurirwa inokusundira kune tex yakakora, uko magumo mashoma anotenga nyore. Mitsetse mishoma kwazvo inoganhurirwa nezvose zvina panguva imwe chete, ndosaka mhinduro ichisiyana pakati pemiti miviri inomhanya chimiro chimwe chete.

Kupwanya uye kutenderedza filament: tex imwe chete, denga mbiri

Tex imwecheteyo inoita zvakasiyana mumaitiro maviri aya nekuti muganho wemiganhu hausi mumwe chete.

In kupwanya, denga ndiro gonhi rekuisa simbi. Magumo ese anofanira kupararira kuita bhandi rinozadza gomba zvakaenzana, pasina mipata uye pasina kupindirana. Migumo mitete inopararira zviri nyore uye inozadza chikamu chakafara, chisina kudzika zviri nani; migumo mishoma, yakakora yakaoma, inodzivirira kuvhurika, uye inogona kusiya makona asina kudya. Saka tex inoshanda inotarwa nekuti simbi yako inobata mativi mangani uye kuti kupararira kwako kwepamberi pekufa kunoshanda sei - kwete nezvinopihwa nedatasheet.

In kutenderedza shinda, denga racho rine bandwidth uye tension. Pakuenzana kwesimba, magumo makumi mana nemasere e2400 tex uye magumo gumi nemaviri e9600 tex anopa huremu hwakafanana paawa. Magumo gumi nemaviri zvinoreva nzira pfupi yekumanikidza uye gwara shoma, izvo zviri nyore kudzora uye zviri nyore kuverengazve. Asi imwe neimwe yemapakeji gumi nemaviri iye zvino inotakura kuyerera kwehukuru kane kana, saka snag imwe, package imwe yakaipa kana tension spike imwe inoonekwa se band defect panzvimbo yakakura. Kutenderedza kunotarisawo nezve bhendi upamhi papass imwe neimwe, izvo zvinoshanduka ne tex: kufamba kwakakombama kunofukidza hupamhi hwakawanda mu traverse imwe chete, izvo zvinoshandura kuti mapasi mangani anovhara layer.

Kufamba-famba kwakakodzera pamagumo 383 kuburikidza nedhiraivha yepultrusion kunogona kuva sarudzo isiriyo pamagumo 12 pamandri. Nhamba imwe chete, denga rakasiyana.

Nhamba yekubuda kwesimba inoyera saizi ye creel yako

Usati wazvipira kushandisa tex, tarisa kuti creel yako inopa chii:

Masvomhu ane mutsetse mumwe chete:kg/h = magumo × (tex ÷ 1000) × kumhanya kwemutsetse (m/min) × 0.06.

Pa 25 m/min, kuburitsa 172.8 kg/h kunotora magumo makumi mana nemasere e 2400 tex, magumo makumi maviri nemana e 4800 tex, kana magumo gumi nemaviri e 9600 tex.

tex	magumo e172.8 kg/awa pa25 m/min	magumo e345.6 kg/awa pa25 m/min
2400	48	96
4800	24	48
9600	12	24

Iyi ndiyo nhamba inotara saizi yecreel, huwandu hwepakeji uye nguva yedoffing. Haikuudze kana mutsetse uchanyorova - ndiko kuverenga kwenguva yekugara pamusoro apa - uye haikuudze kana profile ichazara. Ishandise kuisa saizi yecreel, wobva washandisa dzimwe mbiri kuti uone kana creel yawakaisa saizi inogona kushanda.

Mibvunzo Inowanzo bvunzwa

Ndingangotenga tex yakanyanya kuipa kuti ndideredze mativi?

Unogona, uye pamutsetse wakaganhurirwa we "creel" kazhinji zvakanaka. Tarisa zvinhu zviviri kutanga: nguva yekugara iyo bath yako inopa nekumhanya kwaunoda, uye kana mugumo wetex iyoyo wakaomesesa nhanho yekusagona kwako kutsungirira fiber-content. Kana zvese zvikapfuura, tex yakaomesesa inokunda pakureruka.

Vatengesi vaviri vanotaura mashoko akafanana etex — vanogona kuchinjana here?

Hazvisi hazvo. Bvunzai dhayamita ye filament, huwandu hwemaburi e bushing uye saizi system. Tex imwechete ine tambo yakasiyana yakagadzirwa ichanyorova zvakasiyana uye haizoshanduri simba kuita laminate zvakafanana.

Ko 4800 tex "iri pakati" pe2400 ne9600 here?

Muhukuru, hongu: kaviri nehafu chaiyo. Mukuita, kwete. Inopatsanura magumo nehafu isina kupatsanura nehafu nhamba yematanho ekugadzirisa, uye inowedzera kaviri huwandu hwehuwandu hwemasasi papakeji pane kuhuwedzera kana. Kuchinjana hakusi kwakarongeka, ndosaka sarudzo yepakati kazhinji iri iyo inokodzera mutsetse une fixed creel uye tight tolerance.

Sarudza tex yaunogona kubata

Tex isarudzo yemutsara inopfekwa nehembe dzepepa redata. Tanga kubva pachikamu uye huwandu hwefiber hwakananga, shandura kuita magiramu pamita, patsanura netex kuti uwane magumo, wobva watarisa zvinhu zvitatu zvisingakwanise kuudzwa nekabhuku: kana creel ine nzvimbo, kana imba yekugezera ine nguva, uye kana mugumo mumwe chete wakakodzera kugadziriswa.Tarisa zvigadzirwa zveRuifiber zvekusimbisa fiberglasskuti ndione nzvimbo yekusimbisa iri padivi pemutsetse uyu wekufamba-famba, uye ndiverengekufamba-famba zvakananga kuti pave nekuputika uye kutenderedza filamentpeji usati watumira RFQ inodudza maitiro ako, chikamu, chinangwa Vf uye resin — kana ukatsanangura zvakawanda, mhinduro yakawanda inodzoka yatoenderana nemutsara wako.
