Ko te kanohi arai rongoa he rauemi papanga kore-whatu, he mea taatai, he taatai tupurangi ranei, he tikanga he papanga-maha, te tikanga e kiia nei he hanganga SMS. I tenei wa, ko te rahi o nga paparanga he 5 apa, ara, ko te SMMMS (spunbond, meltblown) kei roto i te polypropylene. Ka whakamahia e te papanga M te papanga miihini whakarewa kore hei papa taatari. Na te mea kua tohaina noa nga kauri he taarua me te rahi o nga waahanga e toru-waahanga, ko te mea nui ko te mea kua hangaia ki nga muka ultrafine, te waahanga motuhake o te muka, me te kaha ki te haangai i nga matūriki adsorb; Ka tohatohahia nga muka hei whakarahi i te maha o nga taapara iti, me te roa o te tohatoha, he rite te rahi, he iti te rahi o te kohinga, he teitei te tātari, na te mea ka taea te tātari tātaritanga o te kanohi tiaki kore-kiri kore. mai i te kanohi whakarake tuku iho.
Ko te papanga SMS kore-whatu e whakamahi ana i te polypropylene (me te bacteriostasis maakuku me te hydrophobicity) hei rauemi matua, a ka tae te diameter muka ki te 0.5-10um. Ko enei muka muka papaha me te hanganga o te kapillary ahurei te whakanui ake i te rahi me te roanga o nga muka mo ia waahanga, na reira ko te mata tohu tohu laser he whakakikoruatia o te papanga S layer polypropylene. He pai te tātari o te rangi o te koriri, he rauemi pai mo te maha o nga masara.
Ka rite ki nga hua hauora me te hauora, nga tohu anti-tinihanga he waahanga nui o nga taonga kanohi.
I enei ra, ka whakaritea ki te hangarau waituhi waituhi tawhito, he tohu nga tohu o te kore-paitini, korekore, poke-kore, kaha-teitei, maamaa, kaha-kore, me te mau i te awangawanga. raru. Ka taea te korero ko te hangarau tohu tohu laser e peia ana i te umanga rongoa mai i te mea i whanau ai.
Ko te maaramatanga o te hangarau tohu tohu laser ko te tikanga kia uru ki te mata o te papanga me te laser me te kaha pūngao nui, kia puta te mata o te papanga hei whakakata i nga mea hohonu, i te tauhohenga matū ranei o te mata o te papanga e pa atu ana ki Te hurihanga o te tae i raro i te mana o te maarama marama Na te mea ko te tukatuka taiaho he tukatuka kore-paapuna, kaore te taputapu e pokanoa ki te arai taara o te papanga mahi, na te mea tere te tukatuka laser, a, kua pangia te taonga tukatuka e te wera i te awangawanga iti kaore e whakaputa . . Na te whakatikatika o te kaha o te whakaahuka laser me te tere o te heke o te kurupae, ka taea te whakamahi i te tukatuka laser ki nga taumata rereke me nga awhe.
I tenei wa, e rua nga tikanga mo te tukatuka laser e whakaaetia ana: te tukatuka hau matū me te tukatuka whakaahua (e mohiotia ana ano ko te tukatuka makariri). I tohua e te Lingxiu Laser te laser ultraviolet poto poto mo te mahi tohu.
Ka mahi te taiaho ultraviolet poto poto i te polymer, ka takahia e ia te here matū o te rauemi, ka nekehia nga maramara rauemi i roto i te ahua o te matūriki iti, ki te hau ranei, na ki te whakatutuki i te kaupapa o te whakakapi me te tango i nga rauemi. , ma te whakaputa i tetahi tohu maeneene, marama me te panui ki roto i te tuhinga. I te mea ko te nuinga o te pngao ka haehae i nga here matū, ka iti noa te hiko ki te hiko wera, ka taea e tenei te whakakore i nga panoni i te rohe o te wera (HAZ) me nga papanga e karapoti ana, te whakarite kia kore e hangaia e nga wera.
Cold working (ultraviolet) photons with high load energy can break the chemical bonds inside the material (especially organic materials) or the surrounding medium, causing non-thermal process damage to the material. This kind of cold working is of special significance in laser marking, because it is not thermal ablation, but it does not produce "thermal damage" auxiliary, cold peeling that breaks the chemical bond, so it does not affect the inner layer and the surrounding area of the processed surface layer. Produce heating or thermal deformation.
Because the transients generated by the hot processing light source cause damage to the outer and middle surface of the mask, which affects the filterability of the mask, the Lingxiu Laser replaces the "cold processing" ultraviolet laser to mark the surface layer of the mask.
