Ukusebenzisa Iphaneli ye-Polycarbonate Ngokwemithombo Ehlukileyo

Ukufundwa Kwiziciro Zomthelelo Wephaneli ye-Polycarbonate

Iziciro ezibalulekile zomthelelo nesibopho se-polycarbonate

Iphaneli ze-polycarbonate zilungile kakhulu ngokuholela, ngaphezu kwemithuba engu-250 kulwandle olunjalo. Zanele ngezimali ezinobukhali eziphakeme kangangokuthi zibambe kahle noma kuzozama ukubamba ngokusebenza kwesayensi. I-coefficient yekhanda iphinde iphinde ibe ngu-0.065 mm ngameter ngadekherideyi eselide ngaselide ngasendulo sengiphondo kaPonemon ekupheleni komnyaka. Nakuba lokhu kudinga ukubala okunye ngokuguquka kwezidingo ngexesha lokufaka, i-polycarbonate isebenza kahle kakhulu phakathi kwegunya elikhulu lemphumelelo, isebenza ngokuchanekileyo ukusuka emsebenzeni oshisayo -40 kuze kube 135 degrees Celsius. Ngokunjalo, izandla ezininzi zisebenzisa iipaneli ze-polycarbonate zokusebenza apho amagunya alula ayakuhlula ngokushesha.

Iingxaki zepolycarbonate kumsebenzi wokwenza umfanekiso

Amaphaneli aqhubekisa ngaphezu kwe-92% yelanga elitholakala, okuyisilinganiso sama-92% njengaselaglasi esihle, futhi amonakala kuphela kabili kuka-8.7 iphawundi ngasenqatini engu-cubic foot ikusho 15.6 iphawundi kwezinye izinketho. Lokhu kwenza kube khona ukukhetha okuhle uma abasebenzi basebenzisa izinto ezilula kodwa ephumelelayo ekulweleni ilanga elihlelekile emakhaya. Lezi zephaneli zingakwaziwa ukuthi zibe yizinhlobo ezahlukene zezigaba, kufana nezigaba ezivamile ze-hyperbolic paraboloid noma izindawo ezimbhaxaka, ngaphandle kokudinga ukuphakelwa kwesiprosothithi yesiphakathi. Isimo sasekhanda sibuyiselela isimo sakhe nangoba kusenziwa lokho. Futhi, amacothi akhethekile asebenza njengokungena kwe-UV ayembula ukuba kube luhlaza nokubright ngeminyaka engama-10. Ngemva kweminyaka engu-10 phansi kwalapha, lezi zephaneli ezimacothi zibuyisela ngaphezu kwe-95% yokucindezelwa kwazo kuqala. Lokhu kuyinhle kunazo zonke izinhlahla eziningi ezazinzulu ezingathandabuzeki ngemuva kwesikhathi. Konke lokhu kusho ukuthi abakhethi bafuna ukusebenzisa i-polycarbonate bangafuna ukuthatha izinto ezinobuthulekayo futhi bezifanele.

Izinkinga: Ukwenzakala kwezulu kanye nokukhulula ukungena kwesithwala

Xa kusekelwa kuzinkinga zokunyakaza kwezulu, kucashunywa ukuthi kugcinenwe izikhala zokunyakazela phakathi kwe-3 kuye ku-5 milimita ngalinye i-metri yesipaneli esifakiwe. Lokhu kusiza ekukhululeni izinkinga ezazama emuva. Ukuze kugcinwe ubuchopho bezisithwala, abayengi kumele bahlale ebucayishini bezizinda ezingaphezu kuka-3 mm xa kuyashaywa imodi kanye nokuthi zonke izimodi ezisetshenziswa ngezibhamu noma izithuthi zokuhlaka zibe yilinye. Umthetho wokushaya waphakade uyisidingo. Ukubhaka izixhumanisi ezithile zekhabhide zibhake phakathi kwe-1,200 kuye ku-1,800 ngomzuzu kususa isithwala phakathi kabili, ngempela ngamathathu amabili. Ngemuva kwalokho, ukufaka imodi ngemfazwe yokuphazanyiswa ngemvula ye-125 digiri siCelsius phakathi kwezintathu kuye kumashiyagalombili kuyenza uhlu oluningi. Oku kubuyisa ukuthintana kwezinhlayiya kanye nokunika umsebenzi wesigaba ukuba kusebenza kabanzi ngexesha elide.

Ukushaywa okuhle kwe-CNC kweziphaneli ze-Polycarbonate ezinendimana ephambene

Ukufinyelela Kwezimali Eziphazanyayo Ngokusetshenzisa Izindlela Zokugcwala CNC

I-CNC machining ingasebenzisa ubukhona obuphelele ku-0.01 mm, okuyinkinga engaphezulu kakhulu kunezindlela eziningi eziqondene njenge-3D printing. Izivivekeli ezixhaswa ngalesi servo zihlenza ukulahlekwa kwezimo zepolycarbonate. Lokhu kwenza kube yisimo sokuba kutholakale izinto ezincane, njengamathithi akhethekileyo ekusabela kuzo izimpawu esibonayo emaphrodukthini. Ngoba kusebenza ngendlela eyilingana phakathi kwemigqa, abayimfundi bafuna imiphumela embalimbali. Futhi, umlalo uphila ngeempawu zakhe ezikhulu zokungabangeli kwezizindlovu. Ngamathandabuzo, ipolycarbonate eqashelwe yi-CNC ibenza kahle kubonke abantu abadinga ukubukeka kahle nokuba kumele abe neminikelo yokweseka ngokuqinile.

Ukukhetha Okuhle Kwezixhamo Nezidingo Zokugcwalisa Ukuprosesa Kwamaphaneli Polycarbonate

Izixhamo ezihle, ezipholishwe ne-carbide enobukhulu be-45–55° bathola ukungabi nembuzi futhi ukunyuka kwesitshiki, okuyisidingo sokukhlinzela iziqhashiso zesitsatshisi. Izidingo ezinconywayo zokugcwalisa zilandelayo:

Ipharamitha	Ubude	Ukuphawula
Isivinini se-spindle	8,000–12,000 RPM	Khipha ukugaya kwezixhobo
Isilinganiso sokudla	0.15–0.25 mm/ubude	Mthambo kuthutha kwesibonelo
Ubude Bezikhuthazo	←1 mm	Mthambo kuthutha kwebhola

Ukunciphisa ngokushesha ngezinyameni ezingavulanga kubona phansi kuka-120°C, ngaphansi kweqondo lokuguquka komphakathi we-145°C, ukuzivikela ukungcono nokuhlukunyamala.

Ukulungiswa Kwezandla Ezinhlelekileyo Ngelishwa Ukunciphisa Kwesibonelo

Iindlela ezilandelanayo zixhobo zikhipha iindawo ezineziphumo ngo-40% kunye nomdwebo wokulungisa, zikhubaza ukucindezelwa kumazibulo angaqhelekanga. Iziphazamiso ezibophelela iipleni zenzela ukuba ziphulaphule iqiniso le-polycarbonate elincinci (2.4 GPa), zicinga ubunzima ngexesha lokulungiswa. Umzuzu wokuphalala emva kokulungiswa kwi-110°C ngomnyaka ka-2–4 uvuselela iistresi ezisebenzileyo kwaye uphinde uzimele umzanyo wemolekyuli engavusazeki.

Isifundo Sekhasi: Iinkcukacha Ezihlala Kakhulu Zokuthutha Mvelaphi Kwiipaneli Ezolungiswa Zepolycarbonate

Umsebenzi wokugcina okwakade kumakhanda e-LED ebombelela ukuthi kube nesilinganiso se-0.05 mm phambi kwezindawo zokufaka ezingu-200. Ngokuhlanganisa izixhobo ezidolophiwe ngendalo neziphumo ezobulawa kwesikhathi esifanayo, ithimba lapho lalimala ivolumu elingu-99.8%—lithembisa amaphepha apansi kwe-CNC angaphathelwa yapolycarbonate abadinga ukucaciswa kwesibonelo, isilinganiso sesigaba, nokukhathala komphini.

Izindlela Zokwenza Okuchithekileyo: Ukunciphisa, Ukubendela, Ne-Ukufomatha Amashiti AsePolycarbonate

Ukunciphisa Okuphelele, Ukugubhuza, Nokuhlinza Ungakhethi Isidingo Esikhethekileyo Sekhanda

Amarhoda e-CNC achaza isilinganiso se-±0.005" usebenzisa izinhlangothi ezintathu ezinezinkcazo, ngelixa i-laser e-10.6 µm engu fiber iphinde iphumele umncipho ongcwele obunjingqu. Kumaqashi athile kuze kube ngu-0.25", izivimba zezinhlangothi ezincane kunaku-12,000 RPM zibangela ukuthi ububi bwegazi bungcono ngama-58%. Izihlangothi ezivimbela ukuxhasana kuzakha amagugu afana ne-0.3 mm akungenamandla—okuyisisekelo sokugubhuza izixhobo zokubona kanye nezinqamlezelo ezingenako ukulahla.

Izindlela Zokubendela Ngokushesha Nokubendela Ngokushesha Kwamandla KumaPhepha AsePolycarbonate

Ukwaliswa okxhwele kuvumela ukugayaya kwesibhamu kuze kube ngu-150° ngaphandle kokuphazamisa ukukhathazeka kwe-UV. Kumaqhezu amathree milimita, umkhawulo wokugayaya ophansi kakhulu ungama-13.5 mm (4.5x ubude) ukulungiselela ukuthembeka kwegesi. Ukuxhasa emva kokwakha kwi-130°F (54°C) ngemizuzwana engu-90 kususa isitresi phakathi futhi kuthuthukisa ukukhathazeka kwezivakashi ngo-22% ezinkingeni ezingashintshwa kahle.

Izidingo Zokudala Ukulungiselela Ukugayaya Okuchasisayo

Ukusebenzisa izixhobo ezingenxa zomkhawulo wengxenye oyisikhathi kungekho 3:1 kususa isitresi sokugayaya ngo-71%. Ukusabela iipaneli kwi-90°F kuthuthukisa ukubonakala ngaphandle kokushintsha umbono wesithunzi. Ukuphola isandla kusayizi esifana no-Ra ←0.8µm kususa izindawo eziphazamisa isitresi, nokukhula kwebhizinisi kubonisa ulwabiso lwezigaba ezingu-40% ekugayayeni kwezihlangothi ze-automotive.

Ukuphola Isandla Nezinye Iindlela Emva Kokwenza Ukuthuthukisa Isebe

Iindlela Zokuphola Ukulungiselela Ukubonakala Kwesihlangothi SePolycarbonate

Ukupolisha kwe-diamond abrasive (3–5 µm grit) ngemuva kwezivikelo ezichemikhali kususa ubunzima bephansi nge-80%, kubeka ukuthunyelwa kwegciwane eliphezulu kunesibonelo se-92%. Ngokusho kweSociety of Manufacturing Engineers (2012), ukupolisha okungaphezu kwesinye sikhuba kumela ukwakha kwebaluleko ngaphandle kokugcina amandla ekukhazimba kungalapha kancane kune-850 J/m²—lokhu kubalulekile kakhulu emabodini enqwelomoya nezinhlelo zokubona.

Izivikelo ezingathinti UV Nezivikelo Ezilahla Ukulahla Ukuqina

Izivikelo eziningaphezu kwezinye zifaka i-acrylic UV blockers ne-silica nanoparticles zangena ubudala bokusebenza ngama-12 ngaphandle kweqondana, zibekisa isimo esihle sesithunywa se-tensile sibaluleke ngema-89% emuva kwezinsuku ezingu-3,000 zeqiniso lesimo (ASTM G154). Lezi zivikelo ezininzi futhi zisusa ukubonakala kwelahlolo ngama-67% bese zenza ukuthunyelwa kwe-UV kube yisikhathi esine ngokusheshayo, zabalaza ukuhlanjulwa ngokuphucula ngaphandle kokulahleka kokuvikelwa.

Ukulungiswa Kwezimali Ezinamandla Ngesilinganiso Sempahla Nokusebenza Kwesayizi Yephansi

Amehluko ebandla elokhanya (Ra 0.8–1.2 µm) esenzela ukulanda ngelokhu kuyakhula izinga lezimali ezingaphezu kwe-24 MPa emaphaneleni evalelwe yamandla. Izindlela zokudweba kancane zenza amehluko ethulwini okhuthazekayo engaqeda kuphela 98% yezici zomthelela wokugcina izici zokukhuseleka kwemithetho ye-ISO ezifuna ukucopheleka nokuhlakanipha, kumasebe abalulekile.
