Ifuro rya EVA riciwe na Laser: Hitamo uburyo bwizewe kugira ngo ubone umusaruro mwiza
Ese ifuro rya EVA ni iki? Ese gucana hakoreshejwe laser birakwiranye neza?
EVA (ethylene-vinyl acetate)ni ifuro ryoroheje, rifunze, rishobora gushonga, rishobora kwifata, kandi rirwanya amavuta n'ubushuhe. Ni byiza kuri laser kurusha ifuro rya PU cyangwa PE. Icy'ingenzi: ntuzigere ukata ifuro rya PVC, PS, cyangwa PP — risohora imyuka ihumanya cyangwa rigafata umuriro byoroshye.
None se, ushobora gukata ifuro rya EVA hakoreshejwe laser?Yego, kandi ikora neza cyane. Ubona ubuziranenge bwa ± 0.1 mm, impande zisukuye, nta kiguzi cyo gukoresha ibikoresho, kandi ikora vuba. Koresha umwuka mwiza gusa — EVA ubwayo nta halogen ifite kandi ifite umutekano.
Gukoresha neza ifuro rya EVA ricanwa na laser
| Ubwoko bw'ibyago | Isoko | Ingamba zo kugenzura |
|---|---|---|
| Guhumeka umwotsi n'imyuka | Ibikoresho byahinduwe | ✅ Gukuramo umwuka urimo umwuka: sohora umwuka hanze cyangwa ukoreshe akayunguruzo ka carbon / HEPA. Kuri laser zo ku meza, korera hafi y'idirishya cyangwa imbere mu gipfundikizo cy'umuriro. |
| Inkongi y'umuriro | Gucana ifuro hakoreshejwe laser (akenshi biturutse ku buryo butari bwo) | ✅ Ntugasige imashini ikora yonyine. Bika CO₂ cyangwa ikizimyamwoto cyumye hafi aho. Sukura umutwe wa laser, lens, n'aho gukorera buri gihe. |
| Indwara y'imirasire ya laser | Imirasire yasubiwemo cyangwa itatanye | ✅ Koresha agakoresho gakingira imirasire gafite agakingirizo k'umutekano. Ambara indorerwamo z'umutekano za laser (OD ≥ 5 ku burebure bw'uburebure bwa laser yawe). Ntukigere ureba neza imirabyo. |
| Ibyago bikomoka ku mashanyarazi / mekanike | Ibikoresho bitwara umuriro mwinshi n'ibinyabiziga bikoresha umuriro | ✅ Menya neza ko imashini ifite ishingiro rikwiye. Komeza ushyireho akabuto ko guhagarara mu gihe cy'impanuka byoroshye. |
Kugereranya hagati y'ifuro rya EVA rikata hakoreshejwe laser n'ubundi buryo
Gukata hakoreshejwe laser ugereranije na CNC Routing
Umuntu utavugana nawe cyangwa umuntu utavugana nawe:Router ya CNC ikoresha agace kazunguruka gasunika ifuro, akenshi kagasiga impande zifunze. Gukata hakoreshejwe laser nta kintu na kimwe gikoraho - nta guhindagurika.
Umuvuduko:Ku ifuro rya EVA rifite ubugari bwa mm 2 kugeza kuri mm 12, gukata hakoreshejwe laser akenshi byihuta cyane kuruta gukoresha uburyo bwo gukata.
Ibisobanuro birambuye:Imashini zikoresha imirasire ya lazeri zishobora gukata utuntu duto cyane hamwe n'agace gato kangana na mm 0.1. Routers zikenera uduce tunini kandi ntizishobora gukata inguni z'imbere zityaye.
Igenamiterere:Uburyo bwo gukoresha CNC busaba gufunga cyangwa ameza y'ubusa kugira ngo ifuro rigume rigororotse. Ukoresheje laser, ushyira ifuro ku buriri - imbaraga rukuruzi n'ameza y'ubuki akenshi birahagije.
Gukata hakoreshejwe laser ugereranije no gukata hakoreshejwe icyuma gica uduce
Igiciro cyo gukoresha ibikoresho:Gukata icyuma gikenera icyuma gihenze cyihariye (akenshi $200–$1000+). Gukata icyuma gikoresheje laser ntibikenera ibikoresho - gusa dosiye ya digitale.
Impinduka mu miterere:Ku bijyanye n'icyuma gishushanyije, guhindura imiterere bivuze gukora icyuma gishya, bifata iminsi cyangwa ibyumweru. Ukoresheje laser, uhindura dosiye hanyuma ugakata imiterere mishya mu masegonda make.
Ingano y'itsinda:Gukata uduce tw’umucanga bifite ishingiro ku buryo bunini cyane (ibice birenga 10.000). Ku bice bito kugeza ku biciriritse (ibice 1 kugeza ku 1000), gukata hakoreshejwe laser birahendutse cyane kuko nta kiguzi cyo gukata uduce tw’umucanga.
Ingorane:Uduce tw'imbere, utwobo duto, n'imiterere igoye birakomeye cyangwa ntibishoboka iyo ukoresheje ibyuma bicukura. Gukata hakoreshejwe laser bibikora byoroshye.
Uburyo bwo gukoresha ifuro rya EVA rikoreshwa mu gukata laser
Gupakira byihariye n'ibikoresho birinda
Ibikoresho byo gutunganya ibikoresho, gupakira ibikoresho by'ikoranabuhanga bigezweho, amasanduku yo kohereza ibikoresho by'ubuvuzi, amasanduku yo kubikamo indege zitagira abapilote.

️ Gukora diorama z'icyitegererezo n'ubwubatsi
Mu bwubatsi bw’inyubako, ameza y’ubutaka, n’amafilimi magufi, ifuro rya EVA rikunze gukoreshwa ku rufatiro rw’ubutaka, ku nyubako, no ku rufatiro rw’ibimera.
Imurikagurisha n'imitako
Ibiraro by'ubucuruzi, amadirishya, n'imitako y'iminsi mikuru akenshi bikoresha ifuro rya EVA mu gukora inyuguti za 3D, ibirango, n'ibikoresho bifite ishusho.
Gukoresha amajwi no kwirinda amajwi
Ifuro rya EVA rifata amajwi amwe kandi rikunze gukoreshwa muri studio zo gufata amajwi, mu byumba byo kwimenyereza no mu biro.
Gupfuka no gufunga mu nganda
Mu nganda, ifuro rya EVA rikoreshwa nk'ibikoresho byo gukubita, udukoresho two gukingira imashini, udukoresho two gushyiramo ibikoresho, n'udukoresho two gufunga.
Igenamiterere ryiza rya Parametre kuri Laser Cutting EVA Foam
| Ubunini bw'ifuro rya EVA | Ingufu (%) | Umuvuduko (mm/s) | Amapasi | Inyandiko |
|---|---|---|---|---|
| mm 1–2 | 20–30% | 25–35 | 1 | Umuvuduko mwinshi, imbaraga nke - birinda gushonga |
| mm 3–4 | 30–40% | 20–25 | 1 | Ingano isanzwe, itanga impande zisukuye |
| mm 5–6 | 40–50% | 15–20 | 1 | Ubufasha bwo mu kirere burafasha cyane hano |
| mm 8–10 | 60–75% | 8–12 | 1–2 | Ibikoresho binini — inzira ebyiri zishobora gukora neza kurushaho |
| mm 12–15 | 75–90% | 5–8 | 2–3 | Bikeneye inzira nyinshi zidafite ubujyakuzimu |
Icyitonderwa:Ifuro ryijimye rya EVA (umukara, ubururu bwijimye, umutuku) rikurura ingufu nyinshi za laser. Rigabanya ingufu ku kigero cya 5–10% ugereranije n'ifuro ryijimye. Ifuro ry'umweru cyangwa umuhondo wijimye rigaragaza cyane kandi rishobora gukenera imbaraga nyinshi gato.
Inama zo kunoza umusaruro mu gihe ukata ifuro rya EVA hakoreshejwe laser
1. Koresha agapapuro ko gupfuka kugira ngo wirinde umwanda w'umwotsi
2. Fungura igikoresho cyo gufasha mu kirere hanyuma ukishyire mu buryo bukwiye

6. Kora ikizamini cy'ibikoresho kuri buri cyiciro gishya
7. Gerageza gushushanya ibyuma bito cyane kugira ngo ubone imiterere mito
Inyigisho y'intambwe ku yindi yo gukata ifuro rya EVA hakoreshejwe laser
Intambwe ya 1 - Tegura dosiye yawe ya vektori
Koresha porogaramu iyo ari yo yose ya vector (LightBurn, LaserGRBL, Adobe Illustrator, CorelDRAW). Shushanya inzira zawe zo gukata nk'imiterere ifunze. Shyira ibara ry'umurongo ku mutuku usanzwe (RGB 255,0,0) hanyuma ushyire ku rwego rwa "Gukata". Nta mirongo ihurirana.
Intambwe ya 2 - Tegura ifuro
Shyira ifuro rya EVA ku gitanda cya laser. Niba ushaka kwirinda umwanda w'umwotsi, shyira kaseti y'umushushanyi ukoresha ikoranabuhanga riciriritse hejuru. Menya neza ko urupapuro rudapfundikiye cyangwa ngo rube rufite iminkanyari.
Intambwe ya 3 – Shyiraho imashini yawe ya EVA ikoze muri laser cut foam
Ukurikije ubunini, shyiramo imbaraga zo gutangira n'umuvuduko. Ku ifuro rya mm 3-4, gerageza imbaraga za mm 35% na mm 22/s nk'ishingiro. Reba imbonerahamwe y'ibipimo mbere muri iyi nyandiko.
Intambwe ya 4 - Kwibanda ku kintu kimwe no kugishyiraho umurongo
Shyiraho intera ikwiye yo gupima (koresha igipimo cyo gupima cyangwa ikizamini cya ramp). Hindura umutwe wa laser ku mfuruka, hanyuma ukoreshe "Frame" muri porogaramu yawe kugira ngo urebe neza agace kaciwemo. Menya neza ko byose bihuye n'ibikoresho byawe.
Intambwe ya 5 - Kora ikizamini cyo gupima
Kata agace gato k'agace k'agace. Reba neza: ese kaciwe neza? Impande zigomba kuba umukara woroshye, ntabwo ari umukara cyangwa ngo zishonge. Hindura imbaraga cyangwa umuvuduko mu ntambwe za 5-10% kugeza igihe wishimiye.
Intambwe ya 6 - Kata akazi ka nyuma
Shyira igishushanyo cyawe hejuru y'ifuro hanyuma utangire gukata. Komeza urebe buri minota ibiri kugira ngo urebe ko hari umuriro cyangwa umwotsi mwinshi. Ntukigere ureka gitemba cyonyine.
Intambwe ya 7 - Kuraho no gusukura
Zimya laser hanyuma utegereze amasegonda make kugira ngo umwotsi ushire. Kuramo ibice hanyuma ukureho kaseti iyo ari yo yose yo gupfuka. Hanagura ibisigazwa bito ukoresheje alcool yo gusuka. Kugira ngo impande zirusheho kuba nziza, shyira vuba agakoresho gashyushya ku murongo.
