Nei Inki dzeUV "dzisina NVP" uye "dzisina NVC" dziri kuva mwero mutsva weindasitiri

Indasitiri yeinki yeUV iri kuchinja zvakanyanya nekuda kwekuwedzera kwemitemo yezvakatipoteredza nehutano. Imwe nzira huru iri kutonga pamusika ndeyekusimudzirwa kwemafomula ekuti "NVP-Free" uye "NVC-Free". Asi sei chaizvo vagadziri veinki vari kusiya NVP neNVC?

Kunzwisisa NVP neNVC

**NVP (N-vinyl-2-pyrrolidone)** imusanganiswa une nitrogen une molecular formula C₆H₉NO, ine pyrrolidone ring ine nitrogen. Nekuda kwekusviba kwayo kushoma (kazhinji kunoderedza viscosity yeinki kusvika 8–15 mPa·s) uye reactivity yakakwira, NVP yakashandiswa zvakanyanya muUV coatings neinki. Zvisinei, maererano neBASF's Safety Data Sheets (SDS), NVP inoiswa muchikamu cheCarc. 2 (H351: supposed carcinogen), STOT RE 2 (H373: organ damage), uye Acute Tox. 4 (acute toxicity). American Conference of Governmental Industrial Hygienists (ACGIH) ine mukana mudiki wekushanda kune threshold limit value (TLV) ye0.05 ppm chete.

Saizvozvowo, **NVC (N-vinyl caprolactam)** yave ichishandiswa zvakanyanya muinki dzeUV. Munenge mugore ra2024, mitemo yeCLP yeEuropean Union yakapa NVC mhando itsva dzenjodzi H317 (kunzwa kweganda) uye H372 (kukuvara kwenhengo). Mafomu einki ane 10 wt% kana kupfuura NVC anofanira kuratidza pachena chiratidzo chengozi yedehenya nemapfupa, zvichiomesa zvakanyanya kugadzirwa, kutakurwa, uye kuwanikwa kwemusika. Makambani ane mukurumbira akadai seNUtec neswissQprint ikozvino ari kushambadza pachena "inki dzeUV dzisina NVC" pamawebhusaiti avo nezvinhu zvekushambadzira kuti vasimbise hunhu hwavo husina njodzi kunharaunda.

Sei "NVC-Free" yava nzvimbo yekutengesa?

Kune mabrandi, kushandisa "isina NVC" zvinoreva kuti kune mabhenefiti akawanda akajeka:

* Kuderedzwa kweSDS njodzi kupatsanurwa

* Zvirambidzo zvekutakura zvishoma (hazvichaonekwi sezvine chepfu 6.1)

* Zviri nyore kutevedzera zvitupa zvine utsi hushoma, kunyanya zvinobatsira muzvikamu zvine chekuita nekurapa nedzidzo.

Muchidimbu, kubvisa NVC kunopa musiyano wakajeka mukushambadzira, green certification, uye mapurojekiti etender.

Kuvapo kweNVP neNVC muUV Inks munhoroondo

Kubva pakupera kwema1990 kusvika kutanga kwema2010, NVP neNVC zvaive zvinhu zvaiwanzoshandiswa mukugadzirisa maUV ink system nekuda kwekuderedza kusimba kwawo uye kuita kwadzo zvakanyanya. Mafomula akajairika einki dzeblack ink jet kare aive ne15–25 wt% NVP/NVC, nepo flexographic clear coats yaive neanenge 5–10 wt%.

Zvisinei, sezvo European Printing Ink Association (EuPIA) yakarambidza kushandiswa kwema monomers anokonzera kenza uye mutagenic, ma NVP/NVC formulations echinyakare ari kutsiviwa nekukurumidza nedzimwe nzira dzakachengeteka dzakadai seVMOX, IBOA, uye DPGDA. Zvakakosha kuziva kuti inki dzakagadzirwa ne solvent kana mvura hadzina kumbobvira dzabatanidza NVP/NVC; aya ma vinyl lactam ane nitrogen akawanikwa chete muma UV/EB curing systems.

Mhinduro dzeUV dzeHaohui dzeVagadziri veInk

Semutungamiri muindasitiri yekupisa UV, Haohui New Materials yakazvipira kugadzira inki dzeUV dzakachengeteka uye dzisingakuvadzi nharaunda. Isu tinotsigira zvikuru vagadziri veinki vanochinja kubva kuinki dzechinyakare kuenda kumhinduro dzeUV nekugadzirisa matambudziko akajairika kuburikidza nerutsigiro rwehunyanzvi rwakagadziriswa. Mabasa edu anosanganisira nhungamiro yekusarudza zvigadzirwa, kugadzirisa maitiro, kugadzirisa maitiro, uye kudzidziswa kwehunyanzvi, zvichiita kuti vatengi vedu vabudirire pakati pemitemo yezvakatipoteredza yakasimba.

Kuti uwane rumwe ruzivo rwehunyanzvi uye mienzaniso yezvigadzirwa, shanyira webhusaiti yepamutemo yeHaohui, kana kuti taura nesu paLinkedIn neWeChat.
