Ka taea e koe te tapahi i te pahuka EVA mā te laser?
Rārangi Kaupapa:
He aha te pahuka EVA?
Ko te pahuka EVA, e mōhiotia ana ko te pahuka Ethylene-Vinyl Acetate, he momo rauemi hangai e whakamahia whānuitia ana mō ngā momo mahi. Ka hangaia mā te whakakotahi i te ethylene me te vinyl acetate i raro i te wera me te pēhanga, ka hua ake he rauemi pahuka pakari, māmā, me te ngāwari. E mōhiotia ana te pahuka EVA mō ōna āhuatanga whakamarie me te mimiti ru, ka waiho hei whiringa rongonui mō ngā taputapu hākinakina, hu, me ngā mahi toi.
Ngā Tautuhinga Pahu Eva Tapahi Taiaho
He tikanga rongonui te tapahi taiaho mō te hanga me te tapahi i te pahuka EVA nā tōna tika me tōna whānui. Ka rerekē pea ngā tautuhinga tapahi taiaho tino pai mō te pahuka EVA i runga i te taputapu tapahi taiaho motuhake, tōna kaha, te matotoru me te mātotoru o te pahuka, me ngā hua tapahi e hiahiatia ana. He mea nui kia whakamātautauhia ngā tapahi me te whakarerekē i ngā tautuhinga kia rite. Heoi, anei ētahi aratohu whānui hei tīmatanga māu:
▶ Mana
Tīmata ki te tautuhinga mana iti iho, tata ki te 30-50%, ā, mārire te whakanui ake mēnā e tika ana. Ko te pahuka EVA matotoru, kikī hoki, me nui ake pea ngā tautuhinga mana, ko te pahuka angiangi ia me iti ake te mana hei karo i te rewa nui, te wera rānei.
▶ Tere
Tīmata ki te tere tapahi taurite, tata ki te 10-30 mm/s. Me whakarerekē pea tēnei i runga i te matotoru me te mātotoru o te pahuka. Ka taea e ngā tere puhoi te hua ake he tapahi ma, engari he pai ake pea ngā tere tere mō ngā pahuka angiangi.
▶ Arotahi
Me whakarite kia tika te arotahi o te reera ki te mata o te pahuka EVA. Mā tēnei ka pai ake ngā hua tapahi. Whāia ngā tohutohu a te kaihanga o te kaitapahi reera mō te whakarerekē i te roa arotahi.
▶ Ngā Tapahi Whakamātautau
I mua i te tapahi i tō hoahoa whakamutunga, whakamātautauhia he tapahi iti ki tētahi tauira o te pahuka EVA. Whakamahia ngā tautuhinga mana me te tere rerekē hei kimi i te huinga tino pai e whakarato ana i ngā tapahi ma, tika, me te kore e wera nui, e rewa rānei.

He haumaru te tapahi i te pahuka EVA mā te rēseri?
Ina pāhekoheko te hihi taiaho ki te pahuka EVA, ka whakamahana, ka mimiti te rauemi, ka tukuna ngā hau me ngā matūriki. Ko ngā auahi e puta mai ana i te pahuka EVA tapahi taiaho he mea hanga ki ngā matū waro mimiti (VOC) me ētahi matūriki iti, paru rānei. Ka haunga pea ēnei auahi, ā, kei roto pea ngā matū pēnei i te waikawa acetic, te formaldehyde, me ētahi atu hua tahunga.
He mea nui kia tika te hauhautanga i te wā e tapahi ana i te pahuka EVA mā te whakamahi i te laser hei tango i ngā kohu mai i te wāhi mahi. Mā te hauhautanga tika ka āwhina i te pupuri i te taiao mahi haumaru mā te ārai i te kohikohinga o ngā hau kino pea, me te whakaiti i te haunga e pā ana ki te tukanga.
He tono rauemi kei reira?
Ko te momo pahuka tino rongonui e whakamahia ana mō te tapahi laser kopahuka polyurethane (pahuka PU)He haumaru te pahuka PU ki te tapahi i te laser nā te mea he iti noa ngā paoa e puta mai ana, ā, kāore e tukuna he matū paitini ina pāngia e te hihi laser. Haunga te pahuka PU, ko ngā pahuka i hangaia mai ite polyester (PES) me te polyethylene (PE)he pai hoki mō te tapahi laser, te whakairo, me te tohu.
Heoi anō, ka taea e ētahi pahuka PVC te whakaputa hau paitini ina whakamahia he laser. He kōwhiringa pai te whakamahi i te mīhini tango auahi hei whakaaro mēnā me tapahi koe i aua pahuka mā te laser.
Pahuka Tapahi: Reera VS. CNC VS. Kaitapa Mate
Ko te whiriwhiri i te taputapu pai rawa atu ka whakawhirinaki nui ki te matotoru o te pahuka EVA, te uaua o ngā tapahi, me te taumata o te tika e hiahiatia ana. He pai ngā maripi mahi, ngā kutikuti, ngā kaitapahi pahuka waea wera, ngā kaitapahi laser CO2, ngā pouara CNC rānei mō te tapahi i te pahuka EVA.
He pai te whakamahi i te maripi koi me te kutikuti mēnā he tika, he ngāwari noa iho ngā taha piko e hiahiatia ana, ā, he iti hoki te utu. Heoi, ko ngā pepa pahuka EVA angiangi anake ka taea te tapahi, te piko rānei ā-ringa.
Mena kei roto koe i te Pakihi, ko te Aunoatanga me te Tika te mea matua hei whakaaroaro māu.
I roto i taua āhuatanga,he mīhini tapahi taiaho CO2, he pouara CNC, me te mīhini tapahi mateme whai whakaaro.
▶ Kaitapa Reera
He mea tika, he mea whai hua hoki te tapahi taiaho, pērā i te taiaho CO2 papamahi, te taiaho muka rānei, mō te tapahi pahuka EVA, inā koa mōngā hoahoa uaua, ngā hoahoa uaua rāneiKa whakaratohia e ngā kaitapahi laserngā taha ma, hiriā, e whakamahia pinepine ana mōtauine nui akengā kaupapa.
▶ Pouara CNC
Mena kei a koe he pouara CNC (Mana Tau Rorohiko) me te taputapu tapahi e tika ana (pēnei i te taputapu hurihuri, i te maripi rānei), ka taea te whakamahi mō te tapahi i te pahuka EVA. Ka tino tika ngā pouara CNC, ā, ka taea te whakahaerengā pepa pahuka matotoru.
▶ Mīhini Tapahi Mate
He mea tika, he mea whai hua hoki te tapahi taiaho, pērā i te taiaho CO2 papamahi, te taiaho muka rānei, mō te tapahi pahuka EVA, inā koa mōngā hoahoa uaua, ngā hoahoa uaua rāneiKa whakaratohia e ngā kaitapahi laserngā taha ma, hiriā, e whakamahia pinepine ana mōtauine nui akengā kaupapa.
Te Painga o te Pahuka Tapahi Taiaho
I te tapahi i te pahuka ahumahi, ko ngā painga otapahi rēserihe mārama rawa atu i runga i ētahi atu taputapu tapahi. Ka taea e ia te hanga i ngā āhua tino pai rawa atu nā tetapahi tika, kāore e pā, me te nuinga o te ctaha hiroki, papatahi hoki.
Ina whakamahia te tapahi wai-pūwero, ka mimitia te wai ki roto i te pahuka mimiti i te wā o te tukanga wehenga. I mua i te tukatuka anō, me whakamaroke te rauemi, he tukanga roa tēnei. Kāore e whakamahia te tapahi taiaho hei tapahi, ā, ka taea e koe tetukatuka tonute rauemi tonu. He rerekē, he tino whakapono te taiaho, ā, koinei te taputapu matua mō te tukatuka pahuka.
Whakamutunga
Kei roto i ngā mīhini tapahi rēseri a MimoWork mō te pahuka EVA he pūnaha tango paoa kua hangaia hei āwhina i te hopu me te tango tika i ngā paoa mai i te wāhi tapahi. Tērā atu huarahi, ka taea te whakamahi i ngā pūnaha hauhautanga tāpiri, pērā i ngā pā hau, i ngā taputapu horoi hau rānei, hei whakarite kia tangohia ngā paoa i te wā tapahi.
Ngā Rauemi Noa mō te tapahi taiaho
Ngā Pātai Auau
Mā te tapahi taiaho ka tukuna e te pahuka EVA he auahi kei roto ngā VOC, te waikawa acetic, me te formaldehyde, he mea kino ki te manawahia. Whakamahia he taputapu tango auahi (hei tauira, Fume Extractor 2000) me tō taputapu tapahi taiaho hei tango i ēnei auahi. Me whakarite kia pai te hau o te wāhi mahi me ngā pā hau, ngā matapihi tuwhera rānei. Āta karohia te pānga roa mā te mau i te manawa manawa mēnā e tika ana. Horoia tonu te pūnaha putanga hau o te taputapu tapahi kia mau tonu ai te pai, nā te mea ka taea e te kohikohinga te whakaiti i te tango auahi me te tūpono ki te ahi.
Ko te matotoru mōrahi e whakawhirinaki ana ki te kaha o te taiaho. Ko ngā tapahi taiaho CO2 papamahi (hei tauira, te Mīhini Tapahi Taiaho Kiriaku) he tikanga ka taea te whakamahi i te pahuka EVA matotoru tae atu ki te 15-20mm. Ko ngā tauira ahumahi pēnei i te Extended Flatbed Laser Cutter 160, he kaha ake, ka taea te tapahi i te pahuka matotoru tae atu ki te 50mm ina honoa ki ngā tere puhoi (5-10 mm/s) kia tino mimiti. Ko te pahuka matotoru me maha ngā haerenga, engari he mea nui ngā tapahi whakamātautau hei karo i ngā tapahi kāore i oti, i te wera nui rānei.
He mea nui ngā tapahi whakamātautau hei whakapai ake i ngā tautuhinga mō tō pahuka motuhake. He rerekē te matotoru me te matotoru o te pahuka EVA, nō reira ahakoa ngā aratohu whānui, ka rerekē pea te kaha me te tere tino pai. Mā te tapahi whakamātautau i runga i tētahi wahi pahuka iti ka āwhina i te tautuhi i te taurite tika—mēnā he nui rawa te kaha ka wera, engari he iti rawa ka waiho he taha taratara. Mā tēnei ka whakarite kia tika, kia hiritia ngā taha o tō kaupapa whakamutunga (hei tauira, ngā urunga nohoanga motuka, ngā mahi toi), ka penapena i te wā me ngā rauemi mā te karo i ngā hapa ki te tapahi taiaho.
