Iyo Gamba Risingasungwe reComposites: Kunyura Kwakadzika muMagadzirirwo eFiberglass Roving

Munyika yemakompositi epamberi, zvinhu zvakaita sekabhoni fiber zvinowanzoba chitarisiko. Asi kuseri kwechigadzirwa chega chega chakasimba, chakasimba, uye chakareruka-kubva pazvikepe zvezvikepe uye mashizha eturbine kuenda kuzvikamu zvemotokari nemadziva ekutuhwina-pane chinhu chakakosha chekusimbisa:fiberglass roving. Iyi inochinjika, inoenderera tambo yegirazi filaments ndiyo bhiza rekushanda kweindasitiri yecomposites. Asi zvinhu zvakakosha izvi zvinogadzirwa sei?

Ichi chinyorwa chinopa kutarisa kwakadzama kune yakaomesesa maindasitiri maitiro ekugadzira fiberglass roving, kubva kujecha mbishi kusvika kune yekupedzisira spool yakagadzirira kutumirwa.

Chii chinonzi Fiberglass Roving?

Usati wanyura mu "sei," zvakakosha kuti unzwisise "chii."Fiberglass rovingmuunganidzwa wemagirazi anofambirana, anoenderera mberi akaunganidzwa kuita tambo imwe chete isina kumonyoroka. Inowanzo kuroverwa pane hombe spool kana kugadzira pasuru. Chimiro ichi chinoita kuti ive yakanakira maitiro uko kusimba kwepamusoro uye nekukurumidza kunyorova-kunze (kuzara neresin) kwakakosha, senge:

-Pultrusion:Kugadzira anogara achiyambuka-chikamu profiles sematanda nemabhawa.

-Filament Winding:Kuvaka midziyo yekumanikidza, mapaipi, uye roketi mota casings.

-Yakachekwa Strand Mat (CSM) Kugadzira:Panochekwa roving yogova zvisina tsarukano mumeti.

-Spray-Up Applications:Kushandisa chopper pfuti kuisa resin negirazi panguva imwe chete.

Chinokosha pakuita kwayo chiri mukuenderera kwayo hunhu uye pristine hunhu hwemunhu wega girazi filaments.

Iyo Manufacturing process: Rwendo kubva kuSand kuenda kuSpool

Kugadzirwa kwefiberglass rovinginoramba ichienderera, yakakwirira-tembiricha, uye yakanyanya otomatiki maitiro. Inogona kukamurwa kuita matanho matanhatu akakosha.

Danho 1: Batching - Iyo Yechokwadi Recipe

Zvinogona kunge zvichishamisa, asi fiberglass inotanga neyakafanana zvinhu semahombekombe: silica sand. Nekudaro, izvo zvigadzirwa zvinosarudzwa zvine hungwaru uye zvakasanganiswa. Musanganiswa uyu, unozivikanwa se "batch," unonyanya kusanganisira:

-Silica Sand (SiO₂):Iyo yekutanga girazi yekare, ichipa iyo yekuumbwa musana.

-Limestone (Calcium Carbonate):Inobatsira kudzikamisa girazi.

-Soda Ash (Sodium Carbonate):Inoderedza kunyunguduka kwejecha, kuchengetedza simba.

-Zvimwe zvinowedzera:Zvishoma zvicherwa zvakaita seborax, ivhu, kana magnesite zvinowedzerwa kuti zvipe zvakati zvinhu zvakaita sekuwedzera makemikari kuramba (seE-CR girazi) kana magetsi ekuisa (E-girazi).

Izvi zvinhu zvakasvibirira zvinoyerwa chaizvo uye zvinosanganiswa muhomogeneous musanganiswa, wakagadzirira choto.

Danho rechipiri: Kunyunguduka - Iyo Moto Shanduko

Batch inodyiswa muchoto chihombe, chegasi-chinobatidzwa chinoshanda pakupisa kunokatyamadza kweanenge.1400°C kusvika 1600°C (2550°F kusvika 2900°F). Mukati meiyi inferno, zvimisikidzo zvakasimba zvinoshanduka, zvichinyungudika kuita homogeneous, viscous fluid inozivikanwa segirazi rakanyungudutswa. Choto chinoshanda nguva dzose, iine batch nyowani yakawedzerwa kune imwe mugumo uye girazi rakanyungudutswa rakadhonzwa kubva kune rimwe.

Danho rechitatu: Fiberization - Kuberekwa kweFilaments

Ichi ndicho chinonyanya kukosha uye chinonakidza chikamu chemaitiro. Girazi rakanyungudutswa rinoyerera richibva muchoto remberi richienda mumichina yakakosha inonzi abushing. A bushing iplatinum-rhodium alloy plate, inopesana nekupisa kwakanyanya uye kuora, ine mazana kana kunyange zviuru zvemakomba akanaka, kana mazano.

Sezvo girazi rakanyungudutswa richiyerera nemazano aya, rinogadzira tuhova tudiki, twakadzikama. Hova idzi dzinobva dzatonhodzwa nekukasira uye dzinokweverwa pasi nemhepo ine mhepo inomhanya iri kure kuzasi. Iyi nzira yekudhirowa inoremedza girazi, ichikwevera mumafilaments akanaka kwazvo ane madhayamita anowanzo kubva pa9 kusvika 24 mamicrometer - akatetepa kupfuura bvudzi remunhu.

Nhanho 4: Kukura Kwekushandisa - Iyo Yakakosha Coating

Pakarepo mafilaments aumbwa, asi asati abatana, anoputirwa nemushonga wemakemikari unozivikanwa se.saizikana acoupling agent. Danho iri rine nharo rakakosha sefiberization pachayo. Iyo saizi inoita akati wandei akakosha mabasa:

-Lubrication:Inodzivirira iyo isina kusimba mafilaments kubva kune abrasion kune mumwe nemumwe uye michina yekugadzirisa.

-Coupling:Inogadzira bhiriji remakemikari pakati peiyo inorganic girazi pamusoro uye iyo organic polymer resin, inoshamisa inovandudza kunamatira uye inoumbwa simba.

-Static Reduction:Inodzivirira kuunganidzwa kwemagetsi emagetsi.

-Kubatana:Inosungira mafilaments pamwechete kuti iite tambo yakabatana.

Iyo chaiyo magadzirirwo eiyo saizi chakavanzika chakadzivirirwa nevagadziri uye chakagadzirirwa kuenderana neakasiyana resin (polyester, epoxy,vinyl ester).

Danho 5: Kuunganidza uye Strand Kuumbwa

Mazana emafilaments ega ega, akakura zvino asangana. Vanounganidzwa pamwe chete pamusoro penhevedzano yemarori, anozivikanwa seshangu dzokuunganidza, kuti vaumbe tambo imwe chete, inopfuurira—iyo nascent roving. Nhamba ye filaments yakaunganidzwa inosarudza yekupedzisira "tex" kana kurema-per-kureba kwekutenderera.

Nhanho 6: Kupeta - Iyo yekupedzisira Package

Iyo inoenderera tambo yekurovhainopedzisira yakuvadzwa pacollet inotenderera, ichigadzira hombe, cylindrical package inonzi "doff" kana "forming package." Kumhanya kwemhepo kunokwira zvisingaite, kazhinji kunodarika 3,000 metres paminiti. Mawinda emazuva ano anoshandisa zvidzoreso zvakaomesesa kuti ive nechokwadi chekuti pasuru yakuvadzwa zvakaenzana uye nekunetsana kwakaringana, kudzivirira tangles uye kutyora muzasi maapplication.

Kana pasuru yakazara yakuvadzwa, inobviswa (inobviswa), inoongororwa mhando, yakanyorwa, uye yakagadzirirwa kutumirwa kune vanogadzira uye vanogadzira vanosanganisa pasirese.

Kudzora Kwemhando: Iyo Isingaonekwe Musana

Mukuita uku kwese, kuomarara kwemhando yekudzora kwakakosha. Automated system uye lab matekiniki anogara achitarisa akasiyana akadai se:

- Filament dhayamita kuenderana

-Tex (linear density)

-Strand kutendeseka uye kusununguka kubva pakuzorora

-Sizing application kufanana

-Package kuvaka mhando

Izvi zvinova nechokwadi chekuti spool yega yega ye roving inosangana neiyo chaiyo miyero inodiwa kune yepamusoro-inoshanda inoumbwa zvinhu.

Mhedziso: Injiniya Inoshamisa muhupenyu hweZuva rega rega

Kusikwa kwefiberglass rovinginyanzvi yeinjiniya yemaindasitiri, inoshandura zvinhu zvakapfava, zvakawandisisa kuita yekusimbisa tekinoroji inoumba nyika yedu yanhasi. Nguva inotevera yaunoona turbine yemhepo ichipinduka zvakanaka, motokari yemitambo yakapfava, kana pombi yefiberglass yakaoma, unozotenda rwendo rwakaoma kunzwisisa rwekuvandudza uye nemazvo rwakatanga nejecha nemoto, zvichikonzera gamba risati raitwa remacomposites: fiberglass roving.
