Igorha elingadungwanga leeComposites: Ukuntywila nzulu kwindlela iFiberglass Roving eyenziwa ngayo

Ehlabathini lee-composites eziphambili, izixhobo ezifana ne-carbon fiber zihlala zibamba ukukhanya. Kodwa emva kwayo yonke imveliso eyomeleleyo, eyomeleleyo, kunye nekhaphukhaphu yefiberglass-ukusuka kwizikhephe zesikhephe kunye neeblayidi ze-injini yomoya ukuya kwiindawo zeemoto kunye namachibi okuqubha-kuyinto esisiseko yokomeleza:ukuzulazula kwefiberglass. Le micu eguquguqukayo, eqhubekayo yemicu yeglasi yeyona nto iphambili kushishino lwecomposites. Kodwa yenziwa njani le nto ibalulekileyo?

Eli nqaku libonelela ngojongo olunzulu kwinkqubo yoshishino ephucukileyo yokudala i-fiberglass roving, ukusuka kwisanti ekrwada ukuya kwi-spool yokugqibela elungele ukuthunyelwa.

Yintoni iFiberglass Roving?

Ngaphambi kokuba ungene kwi "njani," kubalulekile ukuqonda "yintoni."Ukujikeleza kwe-Fiberglassyingqokelela yemicu yeglasi ehambelanayo, eqhubekayo edityaniswe ibe ngumsonto omnye, ongajikanga. Idla ngokubotshelelwa kwi-spool enkulu okanye iphakheji yokwenza. Esi sakhiwo senza ukuba silungele iinkqubo apho amandla aphezulu kunye nokuphuma ngokukhawuleza okumanzi (i-saturation nge-resin) ibalulekile, njenge:

-I-Pultrusion:Ukudala iiprofayili zecandelo elinqamlezayo elingaguqukiyo njengeemitha kunye nemivalo.

-Ukuvala iFilament:Ukwakha iinqanawa zoxinzelelo, imibhobho, kunye ne-rocket motor casings.

-Imveliso yeStrand Mat eQiweyo (CSM):Apho i-roving inqunyulwa kwaye isasazwe ngokungaqhelekanga kwimethi.

-Ukusetyenziswa kokutshiza:Ukusebenzisa i-chopper gun ukufaka i-resin kunye neglasi ngaxeshanye.

Isitshixo ekusebenzeni kwayo kulele kubume bayo obuqhubekayo kunye nomgangatho ococekileyo wemicu yeglasi nganye.

Inkqubo yokuVelisa: Uhambo olusuka eSantini ukuya eSpool

Imveliso yeukuzulazula kwefiberglassyinkqubo eqhubekayo, ubushushu obuphezulu, kunye nenkqubo ezenzekelayo kakhulu. Inokwahlulwa ibe ngamanqanaba amathandathu abalulekileyo.

Inqanaba loku-1: Ukudibanisa-Iresiphi echanekileyo

Isenokumangalisa, kodwa i-fiberglass iqala ngezinto ezifanayo ezinjengolwandle: isanti yesilika. Nangona kunjalo, izinto eziluhlaza zikhethwe ngononophelo kwaye zixutywe. Lo mxube, owaziwa ngokuba yi "batch," ikakhulu iqulathe:

-I-Silica Sand (SiO₂):Iglasi yokuqala yangaphambili, ebonelela ngomqolo wesakhiwo.

-Ilitye likalikalika (iCalcium Carbonate):Inceda ukuzinzisa iglasi.

-I-Soda Ash (iSodium Carbonate):Yehlisa ubushushu bokunyibilika kwesanti, igcina amandla.

-Ezinye izongezo:Izixa ezincinci zeeminerali ezifana neboraksi, udongwe, okanye i-magnesite yongezwa ukunika iimpawu ezithile ezifana nokuxhathisa imichiza okuphuculweyo (njengakwiglasi ye-E-CR) okanye ukugquma kombane (E-glass).

Ezi zixhobo eziluhlaza zilinganiswe ngokuchanekileyo kwaye zixutywe kumxube we-homogeneous, ulungele isithando somlilo.

Inqanaba lesi-2: Ukunyibilika – iNguqu yoMlilo

Ibhetshi yondliwa kwiziko elikhulu, elibaswe ngerhasi yendalo esebenza kumaqondo obushushu amangalisayo aphantse alingane.1400°C ukuya ku-1600°C (2550°F ukuya ku-2900°F). Ngaphakathi kule inferno, izinto eziluqilima ekrwada zenza utshintsho olumangalisayo, zinyibilika zibe yinto enye, ulwelo olubonakalayo olubizwa ngokuba yiglasi etyhidiweyo. Iziko lisebenza ngokuqhubekayo, kunye nebhetshi entsha yongezwa kwelinye icala kunye neglasi etyhidiweyo ezotywe kwelinye.

Inqanaba 3: IFiberization - Ukuzalwa kweeFilaments

Le yeyona nxalenye ibaluleke kakhulu kwaye inomdla kwinkqubo. Iglasi etyhidiweyo iphuma kwiziko elingaphambili ukuya kwisixhobo esikhethekileyo esibizwa ngokuba yi-aukubhuqa. I-bushing yi-platinum-rhodium alloy plate, ekwazi ukumelana nobushushu obugqithisileyo kunye nokubola, equlethe amakhulu okanye amawaka emingxuma emihle, okanye iingcebiso.

Njengoko iglasi etyhidiweyo ihamba kula macebiso, yenza imisinga emincinane, ezinzileyo. Le misinga ke ipholiswa ngokukhawuleza kwaye itsalwe phantsi ngomatshini yi-winder enesantya esiphezulu ebekwe kude ngezantsi. Le nkqubo yomzobo inciphisa iglasi, iyitsale kwiifilaments ezintle kakhulu ezinobubanzi obuqhelekileyo ukusuka kwi-9 ukuya kwi-24 micrometers-encinci kuneenwele zomntu.

Inqanaba lesi-4: Ubungakanani beSicelo – ICoating Crucial Coating

Ngokukhawuleza emva kokuba imicu, kodwa ngaphambi kokuba ibambene, iqatywe ngesisombululo sekhemikhali eyaziwa ngokubaubukhuluokanye ai-arhente yokudibanisa. Eli nyathelo libaluleke kakhulu njengefiberization ngokwayo. Ukulinganisa kwenza imisebenzi emininzi ebalulekileyo:

-Ukuthambisa:Ikhusela i-filaments eethe-ethe kwi-abrasion ngokuchasene nomnye kunye nezixhobo zokusebenza.

-Ukudityaniswa:Yenza ibhulorho yeekhemikhali phakathi kwendawo yeglasi ye-inorganic kunye ne-organic polymer resin, iphucula ngokumangalisayo ukunamathela kunye namandla adibeneyo.

-Unciphiso olungatshintshiyo:Ithintela ukwakhiwa kombane ongatshintshiyo.

-Umanyano:Idibanisa imicu kunye ukwenza intambo ehambelanayo.

Uqulunqo oluthile lokulinganisa luyimfihlo egcinwe ngokusondeleyo ngabavelisi kwaye ilungiselelwe ukuhambelana neerasi ezahlukeneyo (i-polyester, epoxy,vinyl ester).

Inqanaba 5: Ukuqokelela kunye noLwakhiwo lweStrand

Amakhulu emicu ngoku iyadibana. Zihlanganiswe ndawonye phezu koluhlu lwee-roller, ezaziwa ngokuba zizicathulo zokuqokelela, ukwenza intambo enye, eqhubekayo-i-nascent roving. Inani leefayili eziqokelelweyo limisela "i-tex" yokugqibela okanye ubunzima-ngobude be-roving.

Inqanaba lesi-6: Ukuvala – iPhakeji yokuGqibela

Umtya oqhubekayo wokuzulazulaekugqibeleni ibotshelelwa kwikholethi ejikelezayo, isenza iphakheji enkulu, engqukuva ebizwa ngokuba yi "doff" okanye "ukwenza ipakethe." Isantya samajikojiko siphezulu ngokumangalisayo, ngokufuthi sidlula iimitha ezingama-3,000 ngomzuzu. Ii-winders zanamhlanje zisebenzisa ulawulo oluntsonkothileyo ukuqinisekisa ukuba ipakethe ilimele ngokulinganayo kunye noxinzelelo oluchanekileyo, ukuthintela ukungqubeka kunye nokuqhekeka kwizicelo ezisezantsi.

Nje ukuba ipakethe epheleleyo isontiwe, iyakhutshwa (isusiwe), ihlolwe umgangatho, ibhalwe, kwaye ilungiselelwe ukuthunyelwa kubavelisi bezinto ezenziweyo kunye nabavelisi abadibeneyo kwihlabathi liphela.

Ulawulo loMgangatho: Umqolo ongabonakaliyo

Kuyo yonke le nkqubo, ulawulo lomgangatho olungqongqo lubalulekile. Iinkqubo ezizenzekelayo kunye neengcali zaselebhu zihlala zijonga izinto eziguquguqukayo ezifana:

-Ukuhambelana kwedayamitha yefilament

-Tex (ubuninzi bomgca)

-Intembeko yeStrand kunye nenkululeko kwikhefu

-Ubungakanani bokufana kwesicelo

-Umgangatho wokwakha ipakethe

Oku kuqinisekisa ukuba yonke i-spool ye-roving ihlangabezana nemigangatho echanekileyo efunekayo kwimathiriyeli edibeneyo yokusebenza okuphezulu.

Isiphelo: Ummangaliso wobuNjineli kuBomi bemihla ngemihla

Ukwenziwa kweukuzulazula kwefiberglassbubuchule bobunjineli bemizi-mveliso, buguqula imathiriyeli elula, eyintabalala ibe yinto eyomelezwa ngobugcisa obuphezulu obubumba ihlabathi lethu lale mihla. Kwixesha elizayo xa ubona i-injini yomoya ijika kakuhle, imoto yezemidlalo ethambileyo, okanye umbhobho wefiberglass erhabaxa, uya kuluvuyela uhambo oluntsonkothileyo lokuyila izinto ezintsha kunye nokuchaneka okuqale ngesanti kunye nomlilo, okukhokelela kwigorha elingadumanga lemidibaniso: i-fiberglass roving.
