"Kana iwe ukavavaka, vachauya" inogona kunge iri yeHollywood catchphrase, asi inotsanangurawo nzira yekusimudzira iyo composites indasitiri dzimwe nguva inoshandisa - kuunza hutsva hunomanikidza netariro yekuti musika uchashanduka nekufamba kwenguva. Chinja uye ugamuchire. Acell's sheet molding compound (SMC) tekinoroji imwe yakadaro hunyanzvi. Patented pasi rose muna 2008 uye yakaunzwa muUS muna 2010, maitiro aya anopa musanganiswa wezvinhu uye maitiro epamusoro pekuita tsika sandwich molding. Mutengo wemidziyo mukuru wemapanera wakadzikira zvakanyanya pane zvakajairwa kuumba kuumbwa.
Muvambi weiyi tsvarakadenga iboka rekuItaly makemikari tekinoroji Acell (Milan, Italy), yanga ichigadzira yakasarudzika-yakavhurika-sero phenolic foam core ye25-inodzivirira moto zvivakwa. Acell yaida kutsvaga musika wakakura wezvigadzirwa zvayo zvefuro uye yakagadzira nzira yekushandisa furo musanganiswa neSMC kugadzira zvakanaka magonhi uye zvimwe zvigadzirwa zvepaneru zvemusika wekuvaka. Technical partner Acell Italpresse SpA (Bagnatica, Italy nePunta Gorda, Florida) akagadzira uye akavaka mutsara wekugadzira wakazara wekugadzira mapaneru anoumbwa zvinoenderana nematanho akatsanangurwa. "Tinotenda mune yedu bhizinesi modhi yekugadzira maitiro uye zvigadzirwa zvekushandisa pasi rose," akadaro Acell Chief Commercial Officer Michael Free.
Zvimwe ari kutaura chokwadi. Izvi zvakaunza kufarira kwakanyanya muindasitiri iyi. Muchokwadi, Ashland Performance Materials (Columbus, Ohio) yakagadzira mubatanidzwa wakasarudzika neAcell kusimudzira tekinoroji iyi muNorth America. Maitiro eAcell akapihwawo 2011 Composites Excellence Award (ACE) neAmerican Composite Manufacturers Association. (ACMA, Arlington, Virginia) Process Innovation chikamu.
Iyo nyowani yekuumba maitiro ndeye crystallization yehuwandu hukuru hwekutsvagisa uye kuvandudzwa kwemasangweji mapaneru. Dave Ortmyer, COO weItalpresse USA, akatsanangura kuti aripo akaumbwa magonhi madhizaini anogadzirwa kuburikidza neakawanda-nhanho uye yebasa-yakanyanya maitiro ayo anosanganisira kugadzira yemukati furemu, kuchenesa ganda reSMC, kuunganidza zvikamu, uye pakupedzisira, polyurethane foam inodururwa mukati. nokuda kwekudzivirira kwekushisa. Kusiyana neizvi, maitiro eAcell anoburitsa yakaenzana gonhi panhinhanho imwe chete uye nemutengo wakaderera wekutanga. "Yechinyakare SMC gonhi reganda mold inogona kuita mari inosvika mazana matatu emadhora," Ortmyer akadaro. "Maitiro edu anogona kukupa gonhi rakapera kamwe chete, mutengo wematurusi uchave $20,000 kusvika $25,000."
Zvishandiso zvinoita basa guru mukuita. Kusiyana neakawanda phenolic furo, ari akapfava, akapfava uye asina kusimba (seyakasvibira furo remuridzi rinoshandiswa kugadzira maruva), Acell foam musanganiswa wezvishandiso zvekuumba furo rakasimba. m3 (5 kusvika 50 lb/ft3). Iyo furo ine thermal insulation properties, moto, chiutsi uye chepfu (FST) kuramba, uye zvinotora ruzha. Inowanikwawo mumhando dzakasiyana-siyana dzemasero, Free akadaro. Iyo SMC yakazadzwa negirazi inoshandiswa mumapanera egonhi inogadzirwa naAcell, akadaro. Nekuti SMC inowanzoita kubuda mukati mekuumbwa, Ortmeier anoti, furo racho rinoita sechinhu chinofema, chichibvumira gasi kubuda muforoma nemakomba.
Zvisinei, nyaya inokosha ndeyekuwanika. Ortmeier akati vabatsiri vacho vanotarisira kupa zvishandiso zvinodhura kune vagadziri vadiki kana avo vanogadzira zvigadzirwa zvakawanda munguva pfupi. Muchimiro cheSMC compression molding, maturusi akakura uye anodhura, anodaro, kwete chete nekuti zvikamu zvakakura, asiwo nekuti zvinofanirwa kushingirira kupera nekubvaruka kunokonzerwa nekufamba uye kuyerera kweakawanda SMC "macharge" akamisikidzwa. muforoma. . pasi pekumanikidzwa kwakanyanya kwakaiswa.
Nekuti iyo yakanyanya kurongeka Acell foam inoramba iri "brittle" (inoremara) pasi pekumanikidzwa, yakajairwa kudzvanya kudzvanya kuchaipwanya zvachose, saka kuumba kunofanirwa kuve kwakadzikira. Naizvozvo, iyo Acell process inongoshandisa yakaonda ye SMC paganda. Iyo haifambisi kana kuyerera nedivi, saka hapana njodzi yekupfeka pamusoro pechishandiso. Muchokwadi, iyo SMC resin inongoyerera mu-z-direction - maitiro akagadzirirwa kupa kupisa kwakaringana muforoma kunyungudutsa iyo SMC matrix, zvichiita kuti imwe resin ipinde mumaseru ari padyo nefuro sezvo ichiputsika zvishoma pasi pekumanikidzwa.
"Panguva yekutenderera, iyo SMC goko rinogara rakagadzirwa nemakemikari mufuro," Frey anotsanangura, uye anoti "ganda delamination hazvigoneke." imwe Chombo chakanyanya kusimba. Mutengo wemaviri akatetepa ekuisa (yepamusoro nepasi) ane inodiwa pamusoro penyaya inongova chidimbu chemutengo unodiwa kugadzira simbi kana machined aluminium SMC chishandiso. Mhedzisiro yacho, vanobatana vanoti, inzira inokwanisika inopa huwandu hwakasiyana hwekutengesa pamutengo wezita remari.
Nekudaro, kugona uye kugona hazviregi kuchinjika. Miedzo yakati wandei yakaitwa umo zvinhu zvakarukwa zvaisanganisirwa mulaminate. Izvo zvinongovakwa mukati memukati wepakati, zvichiwedzera kukombama kwesimba remapaneru. Sekureva kweMahara, machira akarukwa aramid, simbi yehuchi uye kunyange pultruded inoisa inogona kubatanidzwa mumasangweji mapaneru uye kudzvanywa panguva yekugadziriswa kwekuwedzera kuputika kuramba, kudzivirira kuba uye nezvimwe. "Tinoda kuti vagadziri vanzwisise kuti maitiro aya anochinjika uye anochinjika," akatsanangura kudaro. "Inogona kugadzira mapaneru akakora kana akatetepa nemutengo wakaderera pasina kumwe kugadziridzwa sekunge gluing kana kumisa."
Iyo process plant, yakagadzirwa neItalpresse yakanangana neAcell, ine 120 tonne downstroke press ine ma plates anopisa kuisa molds for the panels. Iyo yepasi platen yakagadzirirwa kufamba ichipinda nekubuda kunze kwemuchina wotomatiki, uye Ortmeier anoti zvinokwanisika kuwedzera yechipiri inopisa pasi platen kune rimwe divi remuchina kuisa pane imwe mold imwe iri mushipi uchishandisa Layup. chiteshi. Masirabhu ari 2.6m/8.5ft x 1.3m/4.2ft ye “standard” application senge magonhi ekushongedza, asi slabs anogona kugadzirwa kuti aenderane nemapurojekiti chaiwo. Izvo zvakakosha kucherechedza kuti zvinogonekawo kugadzirisa aripo ekudhinda setups kuti aenderane neAcell maitiro, chero kudzvanywa kuchigona kudzorwa (kuburikidza nekufa kunomira) kudzivirira kuwandisa.
Molds inogadzirwa yega yega yega pani purojekiti uye inogona kugadzirwa nenzira dzechinyakare dzekukanda. Kuti uwane yakakwira tsananguro mold pamusoro inoteedzera zvinhu zvakasikwa sehuni kana dombo, fiberglass / polyester mapaneru anoiswa akananga pazvinhu zvesarudzo kugadzira master mapatani epamusoro uye epasi maturusi. Iwo maviri emhando dzemhando dzakatumirwa kune iyo yekutanga, uko maturusi anokandwa mualuminium-nickel alloy. Chishandiso chakatetepa chinopisa nekukurumidza uye chinogona kusimudzwa nekufambiswa nevashandisi vaviri kana chisina basa. Dzimwe sarudzo dzematurusi dziripo, asi matekiniki ekukanda anoburitsa maturusi nemutengo unonzwisisika uye kazhinji 0.75 ″ kusvika 1 ″ (20 kusvika 25 mm) gobvu.
Panguva yekugadzira, mold inogadzirirwa zvinoenderana neinodiwa pamusoro pekupedzisira kwepaneru. Yakasiyana-siyana yekuumbwa yekupetera uye yekupedzisa iripo, Yemahara yakatsanangurwa, kusanganisira yekuumba poda coating (PiMC), inoshandiswa zvakanyanya sprayable pigment poda inonyunguduka uye inopindirana neSMC kugadzira UV uye kukwenya inodzivirira coating. Panel surface color. Dzimwe sarudzo dzinosanganisira kudira jecha rine ruvara kana rechisikigo pamusoro peforoma kutevedzera dombo, kana kuisa chifukidzo chakadhindwa chinogona kuwedzera magadzirirwo uye pateni. Tevere, iyo filament yekumusoro inoiswa pane mold, ipapo iyo girazi-yakazadzwa SMC inochekwa kuita mesh chimiro uye yakaiswa sandara pane yakagadzirira mold.
Chidimbu che1 ″/26mm gobvu Acell foam (zvakare chakachekwa kuita mesh chimiro) chakazoiswa pamusoro peSMC. Chikamu chechipiri cheSMC chinoiswa kune furo pamwe chete nefirimu rechipiri kufambisa kuburitswa kwezvikamu uye nekupa mugero wezvinoputika zvinoburitswa neSMC.
