Kodi thovu la EVA ndi chiyani?
Thovu la EVA, lomwe limadziwikanso kuti thovu la Ethylene-Vinyl Acetate, ndi mtundu wa zinthu zopangidwa zomwe zimagwiritsidwa ntchito kwambiri pazinthu zosiyanasiyana. Limapangidwa pophatikiza ethylene ndi vinyl acetate pansi pa kutentha ndi kupanikizika, zomwe zimapangitsa kuti thovu likhale lolimba, lopepuka, komanso losinthasintha. Thovu la EVA limadziwika ndi mphamvu zake zoteteza komanso zoteteza kugwedezeka, zomwe zimapangitsa kuti likhale lodziwika bwino pazida zamasewera, nsapato, ndi zaluso.
Zokonda za thovu la Eva Cut Laser
Kudula pogwiritsa ntchito laser ndi njira yotchuka yopangira ndi kudula thovu la EVA chifukwa cha kulondola kwake komanso kusinthasintha kwake. Makonzedwe abwino kwambiri odulira pogwiritsa ntchito laser a thovu la EVA amatha kusiyana kutengera chodulira cha laser, mphamvu yake, makulidwe ndi kuchuluka kwa thovu, komanso zotsatira zodulira zomwe mukufuna. Ndikofunikira kuchita ma test cuts ndikusintha ma settings moyenerera. Komabe, nazi malangizo ena oyambira:
▶ Mphamvu
Yambani ndi mphamvu yocheperako, pafupifupi 30-50%, ndipo pang'onopang'ono muwonjezere ngati pakufunika. Thovu la EVA lokhuthala komanso lolimba lingafunike mphamvu yowonjezereka, pomwe thovu lochepa lingafunike mphamvu yocheperako kuti mupewe kusungunuka kapena kuyaka kwambiri.
▶ Liwiro
Yambani ndi liwiro lodula pang'ono, nthawi zambiri pafupifupi 10-30 mm/s. Apanso, mungafunike kusintha izi kutengera makulidwe ndi kuchuluka kwa thovu. Liwiro locheperako lingayambitse kudula koyera, pomwe liwiro lofulumira lingakhale loyenera thovu lopyapyala.
▶ Kuyang'ana Kwambiri
Onetsetsani kuti laser yayang'ana bwino pamwamba pa thovu la EVA. Izi zithandiza kuti kudula kukhale bwino. Tsatirani malangizo omwe aperekedwa ndi wopanga makina odulira laser okhudza momwe mungasinthire kutalika kwa focal.
▶ Kudula Mayeso
Musanadule kapangidwe kanu komaliza, yesani kudula chidutswa chaching'ono cha thovu la EVA. Gwiritsani ntchito mphamvu zosiyanasiyana ndi makonda a liwiro kuti mupeze kuphatikiza koyenera komwe kumapereka kudula koyera komanso kolondola popanda kutentha kwambiri kapena kusungunuka.

Chitsulo cha Thovu Chodulidwa ndi Laser cha Mpando wa Galimoto!
Kodi thovu lodulidwa ndi laser lingakhale lolimba bwanji?
Kodi muli ndi mafunso okhudza momwe mungadulire thovu la eva pogwiritsa ntchito laser?
Makina Odulira a Laser Omwe Amalimbikitsidwa a thovu la EVA
Kodi ndi bwino kugwiritsa ntchito thovu la EVA lodulidwa ndi laser?
Pamene kuwala kwa laser kukakhudzana ndi thovu la EVA, kumatentha ndi kusandutsa nthunzi, kutulutsa mpweya ndi tinthu tating'onoting'ono. Utsi wopangidwa kuchokera ku thovu la EVA lodulidwa ndi laser nthawi zambiri umakhala ndi zinthu zachilengedwe zosasunthika (VOCs) komanso tinthu tating'onoting'ono kapena zinyalala. Utsi uwu ukhoza kukhala ndi fungo ndipo ukhoza kukhala ndi zinthu monga acetic acid, formaldehyde, ndi zina zomwe zimayatsidwa.
Ndikofunikira kukhala ndi mpweya wabwino wokwanira podula thovu la EVA pogwiritsa ntchito laser kuti muchotse utsi pamalo ogwirira ntchito. Mpweya wokwanira umathandiza kuti malo ogwirira ntchito akhale otetezeka popewa kusonkhanitsa mpweya woopsa komanso kuchepetsa fungo logwirizana ndi njirayi.
Kodi Pali Pempho Lililonse Lofunika?
Mtundu wofala kwambiri wa thovu womwe umagwiritsidwa ntchito podula ndi laser ndithovu la polyurethane (PU thovu)Thovu la PU ndi lotetezeka kudula ndi laser chifukwa limatulutsa utsi wochepa ndipo silitulutsa mankhwala oopsa likakumana ndi kuwala kwa laser. Kupatula thovu la PU, thovu limapangidwa kuchokera kupolyester (PES) ndi polyethylene (PE)ndi abwino kwambiri podula, kulemba, ndi kulemba chizindikiro pogwiritsa ntchito laser.
Komabe, thovu linalake lopangidwa ndi PVC lingapangitse mpweya woipa mukamagwiritsa ntchito laser. Chotsukira utsi chingakhale njira yabwino yoganizira ngati mukufuna kudula thovu lotere pogwiritsa ntchito laser.
Thovu Lodula: Laser vs. CNC vs. Die Cutter
Kusankha chida chabwino kwambiri kumadalira makulidwe a thovu la EVA, kuuma kwa kudula, ndi mulingo wolondola wofunikira. Mipeni yogwiritsira ntchito, lumo, zodulira thovu la waya wotentha, zodulira laser za CO2, kapena ma rauta a CNC zonse zingakhale njira zabwino podula thovu la EVA.
Mpeni wakuthwa ndi lumo zingakhale zabwino ngati mukungofunika kugwiritsa ntchito m'mbali zowongoka kapena zosavuta, komanso ndizotsika mtengo. Komabe, mapepala opyapyala a thovu a EVA okha ndi omwe angadulidwe kapena kupindika pamanja.
Ngati muli mu bizinesi, Automation, ndipo Precision ndiye chinthu chofunika kwambiri kuganizira.
Zikatero,chodulira cha laser cha CO2, rauta ya CNC, ndi Makina Odulira Dieziyenera kuganiziridwa.
▶ Chodulira Laser
Chodulira cha laser, monga laser ya CO2 ya pakompyuta kapena laser ya ulusi, ndi njira yolondola komanso yothandiza yodulira thovu la EVA, makamaka kwamapangidwe ovuta kapena ovuta. Zodulira laser zimaperekam'mbali zoyera, zotsekedwandipo nthawi zambiri amagwiritsidwa ntchito pazazikulumapulojekiti.
▶ CNC Rauta
Ngati muli ndi mwayi wogwiritsa ntchito rauta ya CNC (Computer Numerical Control) yokhala ndi chida choyenera chodulira (monga chida chozungulira kapena mpeni), ingagwiritsidwe ntchito kudula thovu la EVA. Ma rauta a CNC amapereka kulondola ndipo amatha kugwira ntchito bwinomapepala okhuthala a thovu.
▶ Makina Odulira Die
Chodulira cha laser, monga laser ya CO2 ya pakompyuta kapena laser ya ulusi, ndi njira yolondola komanso yothandiza yodulira thovu la EVA, makamaka kwamapangidwe ovuta kapena ovuta. Zodulira laser zimaperekam'mbali zoyera, zotsekedwandipo nthawi zambiri amagwiritsidwa ntchito pazazikulumapulojekiti.
Ubwino wa Thovu Lodula Laser
Podula thovu la mafakitale, ubwino wachodulira cha laserzida zina zodulira ndizodziwikiratu. Zitha kupanga mawonekedwe abwino kwambiri chifukwa chakudula kolondola komanso kosakhudzana, ndi c kwambirim'mphepete mwake mopyapyala komanso mwathyathyathya.
Mukagwiritsa ntchito njira yodulira madzi, madzi adzayamwa mu thovu loyamwa madzi panthawi yolekanitsa. Musanagwiritse ntchito, zinthuzo ziyenera kuumitsidwa, zomwe zimatenga nthawi yayitali. Kudula pogwiritsa ntchito laser sikuthandiza ndipo mungathepitirizani kukonzaZinthuzo nthawi yomweyo. Mosiyana ndi zimenezi, laser ndi yokhutiritsa kwambiri ndipo ndi chida chachikulu kwambiri chogwiritsira ntchito thovu.
Mapeto
Makina odulira a laser a MimoWork a thovu la EVA ali ndi makina otulutsira utsi omwe amathandiza kugwira ndi kuchotsa utsi mwachindunji kuchokera pamalo odulira. Kapenanso, makina ena opumira mpweya, monga mafani kapena zotsukira mpweya, angagwiritsidwe ntchito kuonetsetsa kuti utsi ukuchotsedwa panthawi yodulira.
Zipangizo Zodziwika za Kudula kwa Laser
FAQ
Thovu la EVA lodulidwa ndi laser limatulutsa utsi wokhala ndi ma VOC, acetic acid, ndi formaldehyde, zomwe zimakhala zoopsa ngati zilowetsedwa. Gwiritsani ntchito chotsukira utsi (monga Fume Extractor 2000) ndi chotsukira chanu cha laser kuti muchotse utsiwu. Onetsetsani kuti malo ogwirira ntchito ali ndi mpweya wabwino ndi mafani kapena mawindo otseguka. Pewani kuvala chopumira nthawi yayitali ngati pakufunika kutero. Tsukani makina otulutsira utsi a chotsukira nthawi zonse kuti mupitirize kugwira ntchito bwino, chifukwa kuchulukana kwa utsi kungachepetse kuchotsa utsi ndikuyambitsa ngozi ya moto.
Kukhuthala kwakukulu kumadalira mphamvu ya laser. Makina odulira laser a CO2 (monga Acrylic Laser Cutting Machine) nthawi zambiri amagwira thovu la EVA lokhala ndi makulidwe a 15-20mm. Mafakitale monga Extended Flatbed Laser Cutter 160, okhala ndi mphamvu zambiri, amatha kudula thovu lokhala ndi makulidwe a 50mm akaphatikizidwa ndi liwiro lochepa (5-10 mm/s) kuti atsimikizire kuti nthunzi imayamba kupsa. Thovu lokhala ndi makulidwe lingafunike ma pass angapo, koma kudula koyesa ndikofunikira kuti tipewe kudula kosakwanira kapena kuyaka kwambiri.
Kudula koyesera ndikofunikira kwambiri kuti mukonze bwino malo a thovu lanu. Thovu la EVA limasiyana mu kuchuluka ndi makulidwe, kotero ngakhale ndi malangizo wamba, mphamvu ndi liwiro labwino zimatha kusiyana. Kudula koyesera pa chidutswa cha thovu chaching'ono kumathandiza kuzindikira bwino - mphamvu yochulukirapo imayambitsa kuyaka, pomwe masamba ochepa kwambiri amataya m'mbali. Izi zimatsimikizira kuti ntchito yanu yomaliza (monga ma cushion a mipando yamagalimoto, zaluso) ili ndi m'mbali zolondola komanso zotsekedwa, zomwe zimasunga nthawi ndi zinthu popewa zolakwika ndi chodulira cha laser.
