Pendi inogona kuonekwa kwese kwese muhupenyu hwedu, uye isu hatina kujairana nayo.Zvichida kune majasi akadzidzwa muhupenyu, ivo vanonyanya kunyungudika based kana thermosetting.Nekudaro, iyo yazvino budiriro maitiro ndeye UV pendi, inova inoshamwaridzana negirinhi pendi.
Pendi yeUV, inozivikanwa se "pendi yegirinhi inovandudza uye inoshamwaridzana nepakati muzana ramakore rechi21", iri kusimukira pamwero unodarika kaviri kudyiwa kwepagore.Kubuda kwependi yeUV kuchaita shanduko yekudengenyeka kwepasi mumaitiro ekushandisa emajasi echinyakare.Chii chinonzi UV pendi?Kubuda kwayo kuchave nemhedzisiro yei paindasitiri yekugadzira fenicha?
Chii chinonzi UV pendi?
Pendi yeUV inoreva ultra violet yekurapa pendi, kureva, resin coating inoshandisa UV sesimba rekurapa uye nekukurumidza kuyambuka pane tembiricha.Chiedza cheUltraviolet chinogadzirwa nemidziyo yakakosha, uye maitiro ayo chinhu chakagezwa chinoburitsa chimiro chemakemikari kuburikidza nemwenje weUV mwenje uye shanduko kubva kumvura kuenda kune yakasimba inonzi UV kurapa maitiro.
UV yekurapa tekinoroji ndeyekuchengetedza simba, yakachena uye inoshamwaridzika tekinoroji.Inochengetedza simba - kushandiswa kwayo kwesimba kunongova chikamu chimwe chete kubva muzvishanu cheiyo yekurapa kwekupisa.Haina zvinonyungudutsa, haina kusvibisa zvishoma kunharaunda yezvakatipoteredza, uye haibudisi gasi rine chepfu necarbon dioxide mumhepo.Iyo inozivikanwa se "green technology".UV yekurapa tekinoroji imhando yephotoprocessing tekinoroji inogonesa iyo liquid epoxy acrylic resin kuti iite polymerized kuita yakasimba panguva yekumhanya kukuru ne UV irradiation ine imwe wavelength.Mufananidzo wekurapa maitiro ndiwo chaiwo mufananidzo wakatangwa polymerization uye muchinjiko wekubatanidza maitiro.UV machira anorapika akave achizivikanwa pamwe chete neindasitiri yekupotera nekuda kwepamusoro-soro yekuvharisa kurapa uye hunhu hunoenderana nenharaunda.
Zvakawanda sei zvaunoziva nezve UV pendi?Muna 1968, Bayer akatungamira mukushandisa iyo UV yekurapa sisitimu yeunsaturated resin uye benzoic acid kugadzira zvigadzirwa zvekutengesa, uye yakagadzira chizvarwa chekutanga cheUV yekurapa machira.Mukutanga 1970s, Sun Chemical Company uye immontconciso kambani yakagadzira UV inorapika inki zvakateerana.
Mukutanga kwema1980, vagadziri vepasi veTaiwan vakatanga kudyara nekuvaka mafekitori munyika huru, uye uvpaint application uye tekinoroji yekugadzira zvakaunzwa zvakare.Asati asvika pakati pemakore ekuma1990, uvcoatings ainyanya kushandiswa kugadzira bamboo uye huni pasi pekugadzirisa uye kupurisa kwepurasitiki yekuputira, uye ainyanya kujeka.
Mumakore achangopfuura, nehukuru-hukuru hwekugadzirisa fenicha yemumba, uvpaint yakapinda zvishoma nezvishoma mumunda wekuputira huni, uye zvakanakira zvayo zvakazivikanwa zvakanyanya.Parizvino, uvpaint yakashandiswa zvakanyanya mumapepa, mapurasitiki, simbi, girazi, ceramics nedzimwe minda, uye iri kusimukira munzira yekushanda.
Musika tarisiro yeUV coatings
UV pendi, yakawanda sei yaunoziva nezve echinyakare machira anoshandiswa muindasitiri yefenicha yepamba parizvino achiri kunyanya Pu, PE uye NC.Kuburikidza nekuvaka kwekupfapfaidza, kushanda kwakaderera, uye zvakaoma kutora vashandi uye mutengo wevashandi wakakwirisa.Chete nekuvandudza dhigirii rekugadzira otomatiki emabhizinesi ekugadzira fenicha vanogona kutyora bhodhoro rekusimudzira uye kugadzirisa bhizinesi.Nekune rimwe divi, iyo VOC inoburitswa nemafekitori efenicha vachishandisa machira echinyakare yave chinhu chakakosha chekusvibisa kwezvakatipoteredza.Parizvino, hupfumi hwepasi-kabhoni uye kushandiswa kwegirinhi kwakakurumbira, izvo zvinozoburitsa hutsva hutsva hwehunyanzvi uye zvipingamupinyi zvekutengeserana.Nyika dzakasimukira dzakaita seEurope neUnited States dzakagadzira uye dzakapa akati wandei matanho ekukurudzira indasitiri yefenicha kuti isimudzire kune girinhi nekuchengetedzwa kwezvakatipoteredza.Vagadziri vemidziyo yemumba, kunyanya mabhizinesi akatarisana nekutengesa kunze kwenyika, ari kusangana nematambudziko ega zvisati zvaitika.
Pasi pemamiriro ekusimudzira indasitiri, uvcoatings inoenderana nemaitiro enguva uye inova maitiro matsva mukuvandudza kwekupfekedza fenicha.Zvakanakira nharaunda-inoshamwaridzika uye kuchengetedza simba uye emission kuderedza coating zviri kubuda zvishoma nezvishoma, izvo zvakakwezvawo kutarisa kweakakodzera madhipatimendi enyika.Chirongwa cheMakore Gumi nerimwechete chekusimudzira indasitiri yekupfeka uye yepakati uye yenguva refu chirongwa chekuvandudza kwesainzi uye tekinoroji yeindasitiri yekupotera inoisa pachena kudiwa kwekuvandudza zvine hushamwari maVhizha eUV.Pendi yeUV yave kuda kusimuka kekutanga muindastiri, uye tarisiro yemusika haienzaniswi.
