Warshada khad UV waxa ay ku socotaa isbedel la taaban karo oo ay wado kor u kaca heerarka deegaanka iyo caafimaadka. Mid ka mid ah isbeddelada ugu weyn ee ka taliya suuqa ayaa ah horumarinta "NVP-free" iyo "NVC-Free" qaababka. Laakiin sababta dhabta ah ee soosaarayaasha khadku uga guurayaan NVP iyo NVC?
Fahamka NVP iyo NVC
**NVP (N-vinyl-2-pyrrolidone)** waa dareere falcelin leh oo nitrogen ka kooban oo wata qaacidada kelli C₆H₉NO, oo leh giraanta pyrrolidone ee nitrogen ka kooban. Mawduuciisa hooseeya awgeed (badanaa hoos u dhigaya viscosity ga 8-15 mPa·s) iyo falcelinta sare, NVP ayaa si weyn loogu isticmaalay daaha UV iyo khadadka. Si kastaba ha ahaatee, marka loo eego BASF's Safety Data Sheets (SDS), NVP waxaa loo kala saaray inuu yahay Carc. 2 (H351: looga shakisan yahay kansarka), STOT RE 2 (H373: dhaawaca xubnaha), iyo Sun Ba'an. 4 (sumo degdeg ah). Shirka Maraykanka ee Nadaafiyayaasha Warshadaha Dawladda (ACGIH) ayaa si adag u xaddiday soo-gaadhista shaqada ee qiimaha xadka xadka (TLV) ee kaliya 0.05 ppm.
Sidoo kale, **NVC (N-vinyl caprolactam)** ayaa si weyn looga shaqeeyay khadadka UV. Qiyaastii 2024, xeerarka CLP ee Midowga Yurub waxay u qoondeeyeen kala-soocida khatarta cusub H317 (dareenka maqaarka) iyo H372 (dhaawaca xubnaha) NVC. Qaababka khadku ka kooban yahay 10 wt% ama ka badan NVC waa in ay si muuqata u muujiyaan calaamad halis ah oo dhafoor iyo iskutallaabta ah, taas oo si weyn u adkeynaysa wax soo saarka, gaadiidka, iyo gelitaanka suuqa. Noocyada caanka ah sida NUtec iyo swissQprint hadda waxay si cad ugu xayeysiiyaan "khdadka UV-la'aanta NVC" shabakadahooda iyo agabka xayaysiinta si ay u xoojiyaan aqoonsigooda deegaanka-saaxiibtinimo.
Waa maxay sababta "NVC-free" u noqonayaan goob wax lagu iibiyo?
Noocyada, qaadashada "NVC-free" waxay u tarjumaysaa faa'iidooyin badan oo cad:
* Kala soocida khatarta SDS oo la dhimay
* Xayiraadaha gaadiidka hoose (oo aan hadda loo kala saarin sun 6.1)
* U hoggaansanaanta fudud ee shahaado-sii daynta hoose, gaar ahaan faa'iido u leh qaybaha xasaasiga ah sida deegaanka caafimaadka iyo waxbarashada.
Marka la soo koobo, baabi'inta NVC waxay si cad u soo bandhigaysaa kala duwanaanshaha suuq-geynta, shahaadada cagaaran, iyo mashaariicda qandaraasyada.
Joogitaanka taariikhiga ah ee NVP iyo NVC gudaha UV Inks
Laga soo bilaabo dabayaaqadii 1990-meeyadii ilaa horraantii 2010-meeyadii, NVP iyo NVC waxay ahaayeen dareerayaal fal-celin caadi ah oo ku jira hababka khad UV-ga caadiga ah sababtoo ah hoos u dhigistooda wax-ku-oolka ah iyo falcelinta sare. Qaababka caadiga ah ee khadadka madow ee taariikh ahaan ka kooban 15-25 wt% NVP/NVC, halka jaakadaha jilicsan ee jilicsan ay lahaayeen qiyaastii 5-10 wt.
Si kastaba ha ahaatee, tan iyo markii Ururka Daabacaada Yurub (EuPIA) uu mamnuucay isticmaalka monomers-ka kansarka iyo mutagenic, qaababka NVP/NVC ee dhaqameed si degdeg ah ayaa loogu beddelayaa beddelaad badbaado leh sida VMOX, IBOA, iyo DPGDA. Waxaa muhiim ah in la ogaado in khadadka ku salaysan dareeraha ama biyaha aan waligood lagu darin NVP/NVC; Lactamyada vinyl-ka ee ka kooban nitrogen waxaa si gaar ah looga helay hababka daaweynta UV/EB.
