Kwizicelo apho umthengi engumsebenzisi wokugqibela, imathiriyeli edibeneyo ngokuqhelekileyo kufuneka ihlangabezane neemfuno ezithile zobuhle.Nangona kunjalo,iifiber-reinforced materialszixabiseke ngokulinganayo kwizicelo zoshishino, apho ukuxhathisa umhlwa, ukomelela okuphezulu kunye nokuqina ngabaqhubi bentsebenzo.#INcwadi yeSixhobo#Umsebenzi#Layisha
Nangona ukusetyenziswa kwezinto ezihlanganisiweyo kwiimarike zokuphela komsebenzi ezifana ne-aerospace kunye neemoto ziye zatsala ingqalelo kwishishini elibanzi, inyani kukuba uninzi lwezixhobo ezidibeneyo ezisetyenzisiweyo zisetyenziswa kwiindawo ezingasebenzanga kakhulu.Imarike yokuphela kweshishini iwela kolu luhlu, apho iipropathi zezinto eziphathekayo zihlala zigxininisa ukuxhathisa kwe-corrosion, ukumelana nemozulu kunye nokuqina.
Ukuqina yenye yeenjongo ze-SABIC (eseRiyadh, eSaudi Arabia), ekwiziko lokuvelisa i-op Zoom eBergen, eNetherlands.Isityalo saqala ukusebenza ngo-1987 kwaye sisebenza nge-chlorine, i-acids eqinile kunye ne-alkali kumaqondo aphezulu.Le yimeko-bume eyingozi kakhulu, kwaye imibhobho yentsimbi inokusilela kwiinyanga nje ezimbalwa.Ukuze kuqinisekiswe ukuxhathisa ubuninzi be-corrosion kunye nokuthembeka, i-SABIC ikhethe i-glass fiber eqiniswe iplastiki (i-GFRP) njengemibhobho engundoqo kunye nezixhobo kwasekuqaleni.Izinto eziphathekayo kunye nokuphuculwa kwemveliso kwiminyaka edlulileyo kuye kwakhokelela ekuyilweni kweengxenye ezidibeneyo Ubude bobomi bandiswa ukuya kwiminyaka engama-20, ngoko akukho mfuneko yokutshintshwa rhoqo.
Ukususela ekuqaleni, iVersteden BV (iBergen op Zoom, eNetherlands) yasebenzisa imibhobho ye-GFRP eyenziwe nge-resin, izitya kunye namacandelo avela kwi-DSM Composite Resins (ngoku eyinxalenye ye-AOC, Tennessee, USA kunye ne-Schaffhausen, eSwitzerland).Itotali yeekhilomitha ezingama-40 ukuya kwezingama-50 zemibhobho ehlanganisiweyo yafakelwa kumzi-mveliso, kuquka malunga nama-3,600 amacandelo emibhobho enobubanzi obahlukeneyo.
Ngokuxhomekeke kuyilo, ubungakanani kunye nobunzima benxalenye, amacandelo adibeneyo aveliswa ngokusebenzisa i-filament winding okanye iindlela ezibekwe ngesandla.Ubume bombhobho obuqhelekileyo bubandakanya i-anti-corrosion layer yangaphakathi kunye nobukhulu be-1.0-12.5 mm ukufezekisa ukuchasana kweekhemikhali.Uluhlu lwesakhiwo se-5-25 mm lunokubonelela ngamandla omatshini;i-coat yangaphandle imalunga ne-0.5 mm ubukhulu, enokukhusela indawo yefektri.I-liner inikezela ukuchasana kweekhemikhali kwaye isebenza njengomqobo wokusabalalisa.Lo maleko otyebileyo ngentlaka wenziwa ngeveli yeglasi engu-C kunye nemethi yeglasi engu-E.Ubungakanani obuqhelekileyo obuqhelekileyo buphakathi kwe-1.0 kunye ne-12.5 mm, kwaye ubukhulu beglasi / i-resin ratio yi-30% (esekelwe kubunzima).Ngamanye amaxesha umqobo we-corrosion utshintshwa kunye ne-thermoplastic lining ukubonisa ukuchasana okukhulu kwizinto ezithile.Izinto eziphathekayo zingabandakanya i-polyvinyl chloride (PVC), i-polypropylene (PP), i-polyethylene (PE), i-polytetrafluoroethylene (PTFE), i-polyvinylidene fluoride (PVDF) kunye ne-ethylene chlorotrifluoroethylene (ECTFE).Funda ngakumbi ngale projekthi apha: “Imibhobho ekwazi ukumelana nokutyiwa kumgama omde.”
Amandla, ukuqina kunye nobunzima obulula bezinto ezidibeneyo ziba luncedo ngakumbi kwintsimi yokuvelisa ngokwayo.Umzekelo, iCompoTech (iSušice, iRiphabhlikhi yaseCzech) yinkampani yenkonzo edibeneyo ebonelela ngokuyilwa kwezinto ezidibeneyo kunye nokuveliswa.Izibophelele kwizicelo eziphambili kunye ne-hybrid filament winding.Iphuhlise ingalo yerobhothi ye-carbon fiber ye-Bilsing Automation (Attendorn, eJamani) ukuhambisa umthwalo we-500 Kilogram.Umthwalo kunye nezixhobo ezikhoyo zentsimbi / i-aluminium zifikelela kwi-1,000 kg, kodwa i-robot enkulu ivela kwi-KUKA Robotics (e-Augsburg, eJamani) kwaye inokusingatha kuphela i-650 kg.I-aluminiyam yonke enye isenzima kakhulu, inika umthwalo ohlawulayo / ubunzima besixhobo se-700 kg.Isixhobo se-CFRP sinciphisa ubunzima bubonke ukuya kuma-640 kg, okwenza ukusetyenziswa kweerobhothi kube nokwenzeka.
Elinye lamacandelo e-CFRP i-CompoTech enikezelwe kwi-Bilsing yi-boom e-T-shaped boom (i-T-shaped boom), eyi-T-shaped beam eneprofayili yesikwere.I-boom ene-T yinto eqhelekileyo yezixhobo ezizenzekelayo ezenziwe ngentsimbi kunye / okanye i-aluminium.Isetyenziselwa ukudlulisa iinxalenye ukusuka kwelinye inyathelo lokuvelisa ukuya kwelinye (umzekelo, ukusuka kumshicileli ukuya kumatshini wokubhoboza).I-boom ene-T ixhunywe ngomatshini kwi-T-bar, kwaye ingalo isetyenziselwa ukuhambisa izinto okanye iindawo ezingagqitywanga.Inkqubela phambili yakutsha nje kwimveliso kunye noyilo iphucule ukusebenza kweepiyano zeCFRP T ngokweempawu eziphambili zokusebenza, ezona ziphambili kukungcangcazela, ukuphambuka kunye nokuguqulwa.
Olu yilo lunciphisa ukungcangcazela, ukuphambuka kunye nokuguqulwa koomatshini bomzi-mveliso, kwaye kunceda ekuphuculeni ukusebenza kwamacandelo ngokwawo kunye noomatshini abasebenza nabo.Funda ngakumbi malunga neCompoTech boom apha: "I-T-Boom ehlanganisiweyo inokukhawulezisa i-automation yemizi-mveliso."
Ubhubhani we-COVID-19 uye waphefumlela izisombululo ezinomdla ezisekwe ekusombululeni imingeni ebangelwa sesi sifo.Yiba nomfanekiso weFiberglass Products Inc. (eKitchener, eOntario, eCanada) yaphefumlelwa yipolycarbonate kunye ne-aluminiyam ye-COVID-19 yesitishi sovavanyo esiyilwe saza sakhiwa yiBrigham kunye neSibhedlele sabaseTyhini (eBoston, Massachusetts, USA) ekuqaleni kwalo nyaka.Khawucinge ngeFiberglass Products Inc.
I-IsoBooth yenkampani isekwe kuyilo olwaphuhliswa ngabaphandi be-Harvard Medical School, evumela oogqirha ukuba bame ngaphakathi ngokwahlukileyo kwizigulana kwaye benze iimvavanyo ze-swab kwizandla zangaphandle ezineglavu.Ishelufu okanye itreyi eyenziwe ngokwezifiso phambi kwedokodo ixhotyiswe ngeekhithi zokuvavanya, izixhobo kunye netanki yokusula iintsholongwane zokucoca iiglavu kunye nezixhobo zokukhusela phakathi kwezigulana.
Uyilo lwe-imagine Fiberglass ludibanisa iiphaneli ezintathu zokujonga i-polycarbonate ebonakalayo kunye neepaneli ezintathu zeglasi ezinemibala yefiber roving/polyester fibre.Ezi ziphaneli zefiber ziqiniswa nge-polypropylene honeycomb core, apho kufuneka ukuqina okongeziweyo.Iphaneli edibeneyo ibunjwe kwaye ifakwe ngengubo yejeli emhlophe ngaphandle.Iphaneli ye-polycarbonate kunye neengalo zengalo zenziwe ngomatshini kwi-Imagine Fiberglass CNC routers;iindawo kuphela ezingaveliswanga endlwini ziiglavu.Idokodo linobunzima obumalunga neekhilogram ezingama-90, linokuthwalwa lula ngabantu ababini, liyi-intshi ezingama-33 ubunzulu, kwaye lilungiselelwe uninzi lweengcango ezisemgangathweni zorhwebo.Ngolwazi oluthe kratya ngesi sicelo, nceda undwendwele: "Izinto ezidityanisiweyo zosinga lweglasi zenza kube lula uyilo lwebhentshi yovavanyo lwe-COVID-19."
