Indasitiri yeinki yeUV iri kuita shanduko yakakosha inotungamirwa nekukwira kwezvakatipoteredza uye hutano zviyero. Imwe nzira huru inotonga musika ndeyekusimudzira kwe "NVP-Yemahara" uye "NVC-Yemahara" maumbirwo. Asi nei chaizvo vagadziri veinki vari kutama kubva kuNVP neNVC?
Kunzwisisa NVP uye NVC
**NVP (N-vinyl-2-pyrrolidone)** initrogen-ine reactive diluent ine molecular formula C₆H₉NO, ine nitrogen-containing pyrrolidone ring. Nekuda kwekuderera kwayo (kazhinji kuderedza inki viscosity kusvika 8–15 mPa·s) uye yakakwirira reactivity, NVP yakashandiswa zvakanyanya muUV coatings neingi. Nekudaro, maererano neBASF's Safety Data Sheets (SDS), NVP inorongedzerwa seCarc. 2 (H351: inofungidzirwa carcinogen), STOT RE 2 (H373: kukuvara kwenhengo), uye Acute Tox. 4 (acute toxicity). Iyo American Conference of Governmental Industrial Hygienists (ACGIH) ine yakaganhurirwa kuratidzwa kwebasa kune chikumbaridzo chemuganho kukosha (TLV) ye 0.05 ppm chete.
Saizvozvo, ** NVC (N-vinyl caprolactam) ** yakashandiswa zvakanyanya mumainki eUV. Muna 2024, European Union's CLP mirau yakapa hutsva hwenjodzi H317 (kukurudzira ganda) uye H372 (kukuvara kwenhengo) kuNVC. Maumbirwo eingi ane 10 wt% kana kudarika NVC anofanirwa kuratidza chiratidzo chengozi yedehenya-ne-crossbones, zvinokanganisa kugadzira, kufambisa, uye kuwana musika. Zvigadzirwa zvine mukurumbira zvakaita seNUtec uye swissQprint zvino shambadza zvakajeka "NVC-yemahara UV ingi" pamawebhusaiti avo uye zvigadzirwa zvekusimudzira kusimbisa kwavo eco-hushamwari zvitupa.
Sei "NVC-Yemahara" Ichiita Nzvimbo Yekutengesa?
Kune mhando, kutora "NVC-yemahara" inoshandura kune akati wandei mabhenefiti akajeka:
* Yakaderedzwa SDS njodzi yemhando
* Zvirambidzo zvakaderera zvekutakura (zvisisiri kuiswa muchetura 6.1)
* Kuteedzera kuri nyore nezvitupa-zvishoma-emission certification, kunyanya zvinobatsira muzvikamu zvine hunyoro zvakaita senzvimbo dzekurapa nedzedzidzo.
Muchidimbu, kubvisa NVC kunopa yakajeka kusiyanisa poindi mukushambadzira, girinhi certification, uye mapurojekiti manyoro.
Nhoroondo Kuvapo kweNVP uye NVC muUV Inks
Kubva mukupera kwema1990 kusvika kumavambo 2010s, NVP neNVC dzaive dzakajairika reactive diluent mumasisitimu einki eUV echinyakare nekuda kwekudzikisira kwavo viscosity uye kuita kwakanyanya. Maumbirwo akajairika eingi nhema inkjet munhoroondo yaive ne15-25 wt% NVP/NVC, nepo majasi akajeka eflexographic aive akatenderedza 5-10 wt%.
Zvakadaro, sezvo European Printing Ink Association (EuPIA) yakarambidza kushandiswa kwecarcinogenic uye mutagenic monomers, zvechinyakare NVP/NVC maumbirwo ari kukurumidza kutsiviwa neakachengeteka dzimwe nzira dzakaita seVMOX, IBOA, uye DPGDA. Izvo zvakakosha kuti uzive kuti ingi-inonyungudika kana mvura-yakavakirwa ingi haina kumbobatanidza NVP/NVC; aya nitrogen-ine vinyl lactam aingowanikwa muUV/EB kurapa masisitimu.
Haohui UV Solutions yeInk Manufacturers
Semutungamiri muindasitiri yekurapa UV, Haohui New Materials yakazvipira kugadzira yakachengeteka, eco-inoshamwaridzika UV ingi uye resin masisitimu. Isu tinonyatso tsigira vanogadzira ingi kushandura kubva kune echinyakare ingi kuenda kune UV mhinduro nekugadzirisa zvakajairika marwadzo mapoinzi kuburikidza neyakagadzirirwa tsigiro yehunyanzvi. Masevhisi edu anosanganisira gwara rekusarudza chigadzirwa, gadziriso yekugadzira, kugadzirisa maitiro, uye kudzidziswa kwehunyanzvi, zvichiita kuti vatengi vedu vabudirire pakati pekuomesa mitemo yezvakatipoteredza.
Kuti uwane rumwe ruzivo rwehunyanzvi uye masampuli echigadzirwa, shanyira Haohui's yepamutemo webhusaiti, kana batanidza nesu pa LinkedIn uye WeChat.
