Polycarbonate (PC) waa mid ka mid ah qalabka ugu badan ee loo isticmaalo thermoplastics-ka injineernimada ee loo isticmaalo muraayadaha baabuurta, qalabka elektaroonigga ah ee macaamiisha, muraayadaha indhaha, iyo qalabka ilaalinta. Xooggeeda saamaynta sare leh, caddeynta indhaha, iyo xasilloonida cabbirka ayaa ka dhigaysa mid ku habboon codsiyada adag. Si kastaba ha ahaatee, cillad la yaqaan oo PC-gu ah waa adkaanta dusha sare ee hooseysa, taasoo keenta xoqid iyo iska caabin liidata - gaar ahaan marka ay soo noqnoqdaan ama xaalado xoqan.
Haddaba, sidee bay soosaarayaashu u horumarin karaan adkeysiga dusha sare ee PC-ga iyagoon wax u dhimin hufnaantiisa ama sifooyinkiisa farsamada? Aan sahaminno xalal wax ku ool ah iyo farsamooyin warshadeed oo la xaqiijiyay si looga gudbo caqabadahaas.
Xalka: Isku dar hagaajinta habaynta iyo wax ka beddelka hantida dusha sare iyadoo la adeegsanayo teknoolojiyada ilaalinta sare.
1. Waxyaabaha lagu daro ee ku salaysan silikoon: Saliid gudaha ah
Ku darista waxyaabaha lagu daro silicone-ka ee waxqabadka sare leh, sida polydimethylsiloxane (PDMS) ama masterbatches-ka ku salaysan siloxane sida Dow MB50-001, Wacker GENIOPLAST, iyo SILIKE Silicone Masterbatch LYSI-413, qaab-dhismeedka polycarbonate (PC) waxay si weyn u wanaajin kartaa waxqabadka agabka. Adigoo isticmaalaya waxyaabaha lagu daro heerka rarista ee 1-3%, waxaad si wax ku ool ah u yareyn kartaa isku-dhafka is-jiidjiidka, kaas oo hagaajiya iska caabbinta xoqidda iyo cimri dhererka labadaba.
Faa'iidooyinka Muhiimka ah: Waxyaabaha lagu daro silicone-kan, oo ah waxyaabaha lagu daro iyo wax-ka-beddelayaasha wax-soo-saarka PC-ga, ma aha oo kaliya inay ilaaliyaan hufnaanta indhaha ee PC-ga laakiin sidoo kale waxay kordhiyaan dufanka dusha sare. Tani waxay keentaa hoos u dhac la taaban karo oo ku yimaada dhaawaca dusha sare inta lagu jiro taabashada xoqidda, taasoo ugu dambeyntii horseedda cimri dheer oo badeecadda ah.
Talo Wax Ku Ool Ah: Si loo hubiyo waxqabadka ugu wanaagsan, waxaa lagama maarmaan ah in la gaaro kala firdhis sax ah iyada oo loo marayo fidinta laba-boolal, taas oo ka caawisa ka hortagga kala-goynta wejiga isla markaana kordhisa faa'iidooyinka waxyaabaha lagu daro.

Qalabkan ku salaysan silikoon wuxuu si gaar ah waxtar ugu leeyahay nidaamyada resin-ka ee PC-ga la jaanqaadaya. Waxay hagaajisaa sifooyinka habaynta iyo tayada dusha sare iyadoo kor u qaadaysa socodka resin-ka, fududeynta buuxinta iyo sii deynta caaryada, yaraynta wareegga extruder-ka, yaraynta isku-dhafka is-xoqidda, iyo bixinta iska caabin sare oo mar iyo xoqid ah. Intaa waxaa dheer, masterbatch-kan ku salaysan siloxane wuxuu u shaqeeyaa sidii wax lagu daro ka hortagga xoqidda, taasoo ka dhigaysa xal aad u fiican oo lagu kordhinayo iska caabinta xoqidda ee alaabada PC-ga iyo ugu dambeyntii hagaajinta waxqabadkooda guud iyo cimri dhererka.
2. Dahaarka adag ee UV-da laga daweyn karo oo leh Nanotechnology
Mari dahaadh adag oo dabiici ah oo aan dabiici ahayn oo heer sare ah oo ku salaysan siloxane ama isku-dhafan (tusaale ahaan, Momentive SilFORT AS4700 ama DuraShield ee PPG). Dahaadhyadani waxay gaaraan adkaanta qalinka ilaa 7H-9H, taasoo si weyn u hagaajinaysa iska caabbinta xoqidda.
Ku dar dahaarka UV-da ee la daweyn karo oo leh nanoparticles (tusaale ahaan, silica ama zirconia) si aad u sii xoojiso iska caabbinta xoqidda.
Faa'iidada: Waxay bixisaa difaac ka dhan ah xoqidda, kiimikooyinka, iyo burburka UV, oo ku habboon codsiyada indhaha iyo baabuurta.
Adeegsiga: Isticmaal dahaarka-mari-gelinta, dahaarka buufinta, ama dahaarka socodka si aad u hesho dhumuc isku mid ah (5-10 µm).
3. Xoojinta Nanocomposite-ka
Ku dar nanofillers sida nanosilica, alumina, ama graphene oxide (0.5-2% miisaan ahaan) matrix-ka PC-ga. Kuwani waxay kordhiyaan adkaanta dusha sare waxayna hagaajiyaan iska caabbinta xirashada iyagoon si weyn u saameyn hufnaanta haddii cabbirka walxaha uu yahay <40 nm.
Tusaale: Daraasaduhu waxay muujinayaan in 1% nanosilica ee ku jira PC-ga ay hagaajin karto iska caabbinta xoqidda Taber 20-30%.
Talo: Isticmaal qalab iswaafajiya (tusaale ahaan, wakiilada isku xidhka silane) si aad u hubiso kala firdhinta isku midka ah iyo inaad iska ilaaliso isku-darka.
4. Isku-darka PC-yada si loo helo waxqabad dheellitiran
Isku qas PC-ga PMMA (10-20%) si aad u xoojiso adkaanta dusha sare ama PBT si aad u hagaajiso adkaanta iyo iska caabbinta xirashada. Isku-darkaani wuxuu dheellitiraa iska caabbinta xoqidda iyo xoogga saameynta ee PC-ga.
Tusaale: Isku darka PC/PMMA oo leh 15% PMMA wuxuu kordhin karaa adkaanta dusha sare isagoo ilaalinaya hufnaanta codsiyada bandhigga.
Digniin: Hagaaji saamiga isku-darka si looga fogaado inuu waxyeeleeyo xasilloonida kulaylka ama adkaanta PC-ga.
5. Farsamooyinka Wax-ka-beddelka Dusha Sare
Daaweynta Balaasmaha: Mari kaydin uumi kiimiko ah oo la xoojiyay oo balaasmaha ah (PECVD) si aad ugu shubto dahaadh khafiif ah oo adag sida silicon oxynitride (SiOxNy) dusha sare ee PC-ga. Tani waxay wanaajisaa iska caabbinta xoqidda iyo sifooyinka xirashada.
Qaab-dhismeedka Laser-ka: Samee qaabab yaryar ama nano-cabbir ah oo ku yaal dusha sare ee PC-ga si loo yareeyo aagga taabashada iyo xoqidda kala firdhisa, taasoo hagaajinaysa cimri dhererka bilicda.
Faa'iidada: Qaab-dhismeedka wuxuu yareyn karaa xoqidda muuqata ilaa 40% codsiyada taabashada sare leh.

Ku dar walxaha silikoonka ah waxyaabaha kale ee lagu daro sida budada micropowders-ka PTFE (polytetrafluoroethylene) (0.5-1%) si aad u hesho saameyn isku mid ah. PTFE waxay xoojisaa dufanka, halka silikoonku uu hagaajiyo iska caabbinta xirashada.
Tusaale: Isku darka 2% silicone masterbatch iyo 0.5% PTFE waxay hoos u dhigi kartaa heerka xirashada 25% marka la isticmaalayo simbiriirixan.
7. Xaaladaha Habaynta ee La Hagaajiyay:
Isticmaal isku-darka xiirashada sare leh si aad si isku mid ah u kala firdhiso waxyaabaha lagu daro iyo kuwa buuxiya. Hagaaji heerkulka habaynta kombiyuutarka (260-310°C) si aad uga fogaato burburka.
Adeegso farsamooyinka qaabaynta saxda ah (tusaale ahaan, qaabaynta duritaanka oo leh qaabab la safeeyey) si loo yareeyo cilladaha dusha sare ee bilaabi kara xoqidda.
Qaybaha la sameeyay ee ku jira 120-130°C si loo yareeyo walbahaarka gudaha, taasoo hagaajinaysa waxqabadka xirashada muddada dheer.
Daawashada Hal-abuurka: Is-bogsiinta iyo Dahaarka DLC oo sii kordhaya
Tiknoolajiyada soo ifbaxaysa sida dahaarka is-bogsiinta (oo ku salaysan kiimikada polyurethane ama siloxane) iyo dahaarka kaarboon-u eg dheeman (DLC) waxay bixiyaan xalal mustaqbalka u adkeysan kara codsiyada PC-yada aadka u waara, ee taabashada sare leh. In kasta oo ay wali tahay mid kharash-dhaaf ah oo loogu talagalay alaabada suuqa ballaaran, haddana teknoolojiyadani waxay muujinayaan ballanqaad ku saabsan elektaroonigga raaxada leh, baabuurta, iyo hawada sare.
