Ngaba ungayisika nge-laser i-EVA foam?
Uluhlu Lomxholo:
Yintoni i-EVA Foam?
I-EVA foam, ekwaziwa ngokuba yi-Ethylene-Vinyl Acetate foam, luhlobo lwezinto ezenziwe ngokwenziwa ezisetyenziswa kakhulu kwiintlobo ngeentlobo zezicelo. Yenziwe ngokudibanisa i-ethylene kunye ne-vinyl acetate phantsi kobushushu noxinzelelo, nto leyo ebangela ukuba ibe yinto eqinileyo, ekhaphukhaphu, neguquguqukayo ye-foam. I-EVA foam yaziwa ngeempawu zayo zokuthambisa kunye nokutsala uloyiko, nto leyo eyenza ukuba ibe lukhetho oludumileyo lwezixhobo zemidlalo, izihlangu, kunye nemisebenzi yezandla.
Useto lwe-Laser Cut Eva Foam
Ukusika nge-laser yindlela edumileyo yokubumba nokusika i-foam ye-EVA ngenxa yokuchaneka kwayo kunye nokuguquguquka kwayo. Useto olufanelekileyo lokusika nge-laser lwe-foam ye-EVA lunokwahluka ngokuxhomekeke kwisicuthi se-laser esithile, amandla aso, ubukhulu kunye noxinano lwe-foam, kunye neziphumo zokusika ezifunwayo. Kubalulekile ukwenza ukusika kovavanyo kunye nokulungisa useto ngokufanelekileyo. Nangona kunjalo, nazi ezinye izikhokelo eziqhelekileyo zokukuqalisa:
▶ Amandla
Qala ngokuseta amandla aphantsi, malunga ne-30-50%, kwaye unyuse kancinci kancinci ukuba kuyimfuneko. Ifoam ye-EVA etyebileyo nexineneyo inokufuna useto lwamandla aphezulu, ngelixa ifoam encinci inokufuna amandla aphantsi ukuze kuthintelwe ukunyibilika okanye ukutsha kakhulu.
▶ Isantya
Qala ngesantya esiphakathi sokusika, ngesiqhelo malunga ne-10-30 mm/s. Kwakhona, unokufuna ukulungisa oku ngokusekelwe kubukhulu kunye nobuninzi befoam. Isantya esicothayo sinokubangela ukunqunyulwa okucocekileyo, ngelixa isantya esikhawulezayo sinokufaneleka kwifoam encinci.
▶ Ukugxila
Qinisekisa ukuba i-laser igxile ngokufanelekileyo kumphezulu we-foam ye-EVA. Oku kuya kunceda ekufumaneni iziphumo ezingcono zokusika. Landela imiyalelo enikwe ngumvelisi we-laser cutter malunga nendlela yokulungisa ubude be-focal.
▶ Ukunciphisa uvavanyo
Ngaphambi kokuba usike uyilo lwakho lokugqibela, yenza ukusika uvavanyo kwinxalenye encinci yesampulu ye-EVA foam. Sebenzisa amandla ahlukeneyo kunye noseto lwesantya ukuze ufumane indibaniselwano efanelekileyo ebonelela ngokusika okucocekileyo nokuchanekileyo ngaphandle kokutsha okanye ukunyibilika kakhulu.

Ngaba Ikhuselekile kwi-Laser-Cut EVA Foam?
Xa umqadi welaser udibana nefoam ye-EVA, uyayifudumeza kwaye uyitshise loo nto, ikhuphe iigesi kunye nezinto ezincinci. Umsi oveliswa yifoam ye-EVA esikiweyo ngelaser uhlala uquka iikhompawundi ze-organic eziguquguqukayo (ii-VOC) kunye namaqhekeza amancinci okanye inkunkuma. Le msi ingaba nevumba elimnandi kwaye inokuba nezinto ezifana ne-acetic acid, i-formaldehyde, kunye nezinye izinto ezibangela ukutsha.
Kubalulekile ukuba kubekho umoya ofanelekileyo xa usika i-laser foam ye-EVA ukuze kususwe umsi kwindawo yokusebenza. Umoya owaneleyo unceda ukugcina indawo yokusebenza ikhuselekile ngokuthintela ukuqokelelwa kweegesi ezinokuba yingozi kunye nokunciphisa ivumba elihambelana nenkqubo.
Ngaba kukho nasiphi na isicelo esibalulekileyo?
Uhlobo oluqhelekileyo lwefoam olusetyenziselwa ukusika nge-laser yiifoam ye-polyurethane (ifoam ye-PU)Ifoam ye-PU ikhuselekile ukuba inqunyulwe nge-laser kuba ivelisa umsi omncinci kwaye ayikhuphi iikhemikhali ezinobungozi xa ivezwe kumqadi we-laser. Ngaphandle kwefoam ye-PU, amafoam enziwe nge-i-polyester (PES) kunye ne-polyethylene (PE)zikwalungele ukusika nge-laser, ukukrola, kunye nokumakisha.
Nangona kunjalo, igwebu elithile elisekelwe kwi-PVC linokuvelisa iigesi ezinobuthi xa usebenzisa i-laser. I-fume extractor inokuba lukhetho olufanelekileyo onokulucinga ukuba ufuna ukusika amagwebu anjalo nge-laser.
Igwebu Lokusika: I-Laser vs. CNC vs. Die Cutter
Ukukhethwa kwesixhobo esifanelekileyo kuxhomekeke kakhulu kubukhulu befoam ye-EVA, ubunzima bokusika, kunye nenqanaba lokuchaneka elifunekayo. Iimela zombane, izikere, izicuthi zefoam ezishushu, izicuthi ze-laser ze-CO2, okanye ii-CNC routers zonke zinokuba ziinketho ezilungileyo xa kufikwa ekusikeni ifoam ye-EVA.
Imela ebukhali kunye nesikere zinokuba lukhetho oluhle ukuba ufuna kuphela ukwenza imiphetho ethe tye okanye elula egobileyo, kwaye ingabizi kakhulu. Nangona kunjalo, zii-foam sheets ze-EVA ezibhityileyo kuphela ezinokusikwa okanye zigotywe ngesandla.
Ukuba ukwiShishini, ukwenza izinto ngokuzenzekelayo, kunye nokuchaneka kuya kuba yeyona nto iphambili ekufuneka uyiqwalasele.
Kwimeko enjalo,umsiki we-laser we-CO2, i-CNC router, kunye nomatshini wokusika i-Diekuya kuqwalaselwa.

Inzuzo yeLaser Cutting Foam
Xa usika i-foam yemizi-mveliso, iingenelo zeumsiki welaserngaphezu kwezinye izixhobo zokusika zicacile. Ingadala imilo emihle kakhulu ngenxaukusika okuchanekileyo nokungahambelaniyo, kunye ne-c eninziumphetho obhityileyo nothe tyaba.
Xa usebenzisa ukusika ngejethi yamanzi, amanzi aya kufunxwa kwifoam efunxayo ngexesha lenkqubo yokwahlula. Ngaphambi kokuba kuqhutyekwe phambili, izinto kufuneka zomiswe, nto leyo ethatha ixesha elide. Ukusika nge-laser akuyisebenzisi le nkqubo kwaye unakoqhubeka uqhubela phambiliNgokwahlukileyo koko, i-laser iyakholisa kakhulu kwaye ngokucacileyo sisixhobo esiphambili sokucubungula i-foam.
Isiphelo
Oomatshini bokusika nge-laser beMimoWork be-foam ye-EVA baxhotyiswe ngeenkqubo zokukhupha umsi ezakhelwe ngaphakathi ezinceda ekubambeni nasekususeni umsi ngqo kwindawo yokusika. Kungenjalo, iinkqubo zokungenisa umoya ezongezelelweyo, ezifana neefeni okanye izicoci zomoya, zingasetyenziselwa ukuqinisekisa ukususwa komsi ngexesha lenkqubo yokusika.

FAQ
I-laser cutting EVA foam ikhupha umsi oqulethe ii-VOC, i-acetic acid, kunye ne-formaldehyde, eziyingozi xa ziphefunyezwa. Sebenzisa i-fume extractor (umz., i-Fume Extractor 2000) kunye ne-laser cutter yakho ukususa le msi. Qinisekisa ukuba indawo yokusebenza inomoya ococekileyo kunye neefeni okanye iifestile ezivulekileyo. Kuphephe ukuvezwa ixesha elide ngokunxiba i-respirator ukuba kuyimfuneko. Coca rhoqo inkqubo yokukhupha umoya ye-cutter ukuze ugcine ukusebenza kakuhle, njengoko ukuqokelelana kwayo kunokunciphisa ukususwa kwe-fume kwaye kubangele iingozi zomlilo.
Ubukhulu obukhulu buxhomekeke kumandla elaser. Izicucu zelaser ze-CO2 zedesktop (umz., umatshini wokusika ilaser we-Acrylic) zihlala ziphatha ifoam ye-EVA enobukhulu obuyi-15-20mm. Iimodeli zoshishino ezifana ne-Extended Flatbed Laser Cutter 160, enamandla aphezulu, zinokusika ifoam enobukhulu obuyi-50mm xa zidibene nesantya esicothayo (5-10 mm/s) ukuqinisekisa ukufuma ngokupheleleyo. Ifoam enobukhulu ingadinga ukudlula izihlandlo ezininzi, kodwa ukusika uvavanyo kubalulekile ukuze kuthintelwe ukusika okungaphelelanga okanye ukutsha kakhulu.
Ukusika kovavanyo kubalulekile ekuphuculeni useto lwefoam yakho ethile. Ifoam ye-EVA iyahluka ngobuninzi nangobukhulu, ngoko ke nangona kukho izikhokelo eziqhelekileyo, amandla afanelekileyo kunye nesantya zinokwahluka. Ukusika kovavanyo kwisiqwenga sefoam esincinci kunceda ekuchongeni ibhalansi efanelekileyo—amandla amaninzi kakhulu abangela ukutsha, ngelixa amagqabi amancinci kakhulu enomphetho okrazukileyo. Oku kuqinisekisa ukuba iprojekthi yakho yokugqibela (umz., imiqamelo yesihlalo semoto, izinto zobugcisa) inemiphetho echanekileyo, evaliweyo, igcina ixesha kunye nezinto ngokuphepha iimpazamo nge-laser cutter.
