Imaski yokhuselo lwezonyango yinto yelaphu engeyiyo eyolukiweyo, edityaniswe yintsusa evele ngokwahlukeneyo okanye engahleliwe, kwaye iyinto ngokubanzi eyakhiwe ngendlela emiselweyo, idla ngokubizwa ngokuba luhlobo lweSMS. Okwangoku, eli nani liphezulu lamanqanaba lo maleko-5, oko kukuthi, SMMMS (spunbond, meltblown) yakhiwa ezinepolypropylene. Lusebenzisa M layer meltblown ilaphu nonwoven njengoko umaleko lokucoca ulwelo. Ngenxa kwimicu yayo randomly asasaza yaye ezintsonkothileyo ubungakanani-ntathu, lo msebenzi osemqoka inkulu kukuba le nto ndiyibhalayo imicu ultrafine, umphezulu indawo ethile ifayibha, kunye nokukwazi adsorb amasuntswana kulindeleke; Imicu ke ngokungenamkhethe zasasazwa ukwenza inani elikhulu kwezikhewu amancinane, kunye nokusasazwa ubude uniform, ubukhulu filter Pore lincinane, kunye nokusebenza lokucoca kakhulu, kangangokuba intsebenzo lokucoca unyango isigqumathelo non-ephothiweyo akhuselayo kude ukusuka kwimaski yesixhobo sobusi.
SMS non-ephothiweyo laphu isebenzisa ezinepolypropylene (kunye bacteriostasis zendalo kunye hydrophobicity) njengoko izinto eziphambili ekrwada, kwaye ubukhulu ifayibha unako ukufikelela 0.5-10um. Ezi fayibha ze-ultrafine ezinesakhiwo esikhethekileyo se-capillary zonyusa inani kunye nobude beefayile kwindawo nganye yecandelo, ukwenzela ukuba umaka wokumakishwa we-laser wenziwe ngendwangu engeyiyo eyolukiweyo ye-S layer polypropylene material. Ilaphu lesitshizi linokuhlanjwa komoya okufanelekileyo kwaye sisixhobo esifanelekileyo kwiimaski ezininzi.
Njengazo zonke iimveliso zonyango nezempilo, amanqaku okuchasana nomgunyathi yinxalenye ebalulekileyo yeemveliso zemaski.
Namhlanje, xa kuthelekiswa ne-inki yemveli technology yoshicilelo, laser ukumakisha neneempawu non-ityhefu, non-yokulihlambela, kahle eliphezulu, inkjet, fineness phezulu, kwaye banxibe ukuxhathisa. ingxaki. Kunokuthiwa ukuba iteknoloji yokumakisha laser sele ababeze ishishini lezonyango ukususela ekuzalweni kwayo.
Umgaqo yobuchwepheshe yokumakisha laser kakhulu ukuba irradiate umphezulu umbandela kunye laser kunye ezixineneyo womelele, kangangokuba umphezulu zokufunda vaporized ukubhentsisa izinto ezinzulu, okanye indlela eekhemikhali komhlaba izinto kusokwe a utshintsho lombala phantsi kwesiphumo sokukhanya kwemitha. Ngenxa laser ukuprosesa processing non-umfowunelwa, isixhobo akayi kuphazamisana zochuku ngqo umphezulu workpiece, ngoko isantya laser processing ikhawuleza kakhulu, kwaye into processing lichatshazelwe ubushushu kuluhlu encinane yaye akafuni ingxolo . . Ngenxa yohlengahlengiso lwamandla ombane we-laser kunye nesantya eshukumayo somthi, ukusetjenziswa kwe-laser kungasetyenziswa kumanqanaba ahlukeneyo kunye nobubanzi.
Okwangoku, kukho imigaqo-nkqubo emibini yokusetyenziswa kwe-laser eyamkelweyo: Ukuphathwa kwe-laser thermal kunye ne-Photochemical process (ekwabizwa ngokuba kusetyenzwa ngokubanda). Lingxiu Laser wakhetha elifutshane-kwamaza laser yelanga ngenkqubo yokumakisha.
Xa short-kwamaza laser yelanga enza izinto Polymer, kuba waphula ngqo iqhina eekhemikhali umbandela, ukwenzela ukuba amaqhekeza eziphathekayo yagqithiselwa ngokohlobo ngamasuntswana amancinci okanye irhasi, khon 'ukuze kuphunyezwe injongo lokuthath'indawo nangokususa izinto , ngaloo ndlela kuveliswa uphawu olugudileyo, olucacileyo nolunokufundeka ngaphakathi kwinto leyo. Ekubeni uninzi lwamandla isetyenziswa ukwaphula iibhondi zeekhemikhali, amandla encinane kakhulu iguqulelwa kwi ngamandla obushushu, nto leyo ngokusisiseko ukuphelisa utshintsho ekufudumaleni kwindawo echaphazelekayo (kwez) kunye nezinto ezingqongileyo, ukuqinisekisa ukuba ezi zibonelelo zokufunda ziya aziyi gqitha yi bubushushu.
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.
