Daaweynta Dusha sare ee Plasma ee Dharka Warshadaha: Eco{0}} Kordhinta Ku-xidhka Saaxiibtinimada
Daaweynta dusha sare ee Plasma waxay wax ka beddeshaa wax soo saarka dharka warshadaha iyadoo lagu beddelayo hababka kiimikada qoyan ee nidaamka qallalan ee laminating, dahaarka, iyo daabacaadda codsiyada. Farsamadani waxay meesha ka saaraysaa dareeraha{1}kusalaysan iyo abuurista biyaha wasakhda iyadoo awood siinaysa:
- Firfircoonida dusha sare ee lebbiska ah ee dunta kakan (tusaale, isku-dhafka tolmada leh, kuwa aan dunta ka samaysan) iyada oo loo marayo ionization gaas la kontaroolay
- Kiimiko{0}ku dheggan bilaashka ah ee dahaarka/daabacaadaha, yaraynta qiiqa VOC 100% marka loo eego hababka dhaqanka
- Ilaalinta hantida badan iyada oo loo marayo hoose - wax ka beddelka dusha sare (micron)<0.1μm depth)
Waa maxay sababta qaybaha warshaduhu u qaataan tignoolajiyada Plasma:
|
Loolanka Warshadaha |
Xalka Plasma |
Faa'iidada Farsamada |
|
Ku-tiirsanaanta kiimikada sunta ah |
Isaga/N₂/O₂ tallaalka balasmaha ayaa beddelaya furayaasha iyo xabagta |
Waxay tirtirtaa isticmaalka formaldehyde/PFOA |
|
Tamarta{0}} qallajin degdeg ah |
Plasma atmospheric waxay ku shaqeysaa 25-40 digrii |
30% tamarta hoose vs. kulaylka daaweynta |
|
adhesion dahaarka liidata |
Micro{0} roughening (Ra 0.5-5μm) + kooxaha shaqeeya (-COOH, -OH) |
Xoogga diirka ↑45% marka la isku daro PP/PET |
