Caagagtu waxay tixraacaan alaabada ugu horrayn ka kooban resins (ama monomers polymerized si toos ah inta lagu jiro farsamaynta), oo lagu kabo waxyaabo lagu daro sida balaastiijiyeyaasha, buuxinta, saliidaha, iyo midabada, kuwaas oo la qaabayn karo qaabka inta lagu jiro habaynta.
Astaamaha Muhiimka ah ee Caagagga:
① Inta badan balaastiiggu waa kuwo khafiif ah oo kiimiko ahaan deggan, adkaysi u leh daxalka.
② iska caabin aad u fiican.
③ Daah-furnaan wanaagsan iyo xirashada caabbinta.
④ Guryaha dahaarka leh ee kuleylka hooseeya.
⑤ Guud ahaan way fududahay in la caareeyo, la midabeeyo, laguna farsameeyo qiimo jaban.
⑥ Inta badan balaastikada waxay leeyihiin caabbinta kulaylka liidata, balaadhinta kulaylka sare, waana kuwo guban kara.
⑦ Degenaansho la'aanta cabbirka, u nugul qallooc.
⑧ Caagag badan ayaa soo bandhiga heerkul hoose oo liita, oo ku noqda xaalad qabow.
⑨ U nugul gabowga.
⑩ Qaar ka mid ah balaastikada ayaa si fudud ugu milma dareerayaasha.
Xabagta phenolicWaxaa si weyn loogu isticmaalaa codsiyada FRP (Fiber-Reinforced Plastic) ee u baahan FST (Dabka, Qiiqa, iyo Sunta). Inkasta oo ay jiraan xaddidaadyo gaar ah (gaar ahaan jajaban), xabagta phenolic ayaa ah qayb weyn oo ah xabagta ganacsiga, oo leh wax soo saar caalami ah oo sannadle ah oo ku dhow 6 milyan oo tan. Resins Phenolic waxay bixiyaan xasillooni cabbir heersare ah iyo iska caabin kiimikaad, iyaga oo ilaalinaya xasilloonida heerkulka u dhexeeya 150-180 ° C. Guryahaan, oo ay weheliso faa'iidooyinkooda wax-qabad-qiimuhu, waxay wadaan isticmaalkooda joogtada ah ee alaabta FRP. Codsiyada caadiga ah waxaa ka mid ah qaybaha gudaha ee diyaaradaha, xadhkaha xamuulka, gudaha gaadiidka tareenada, tuubooyinka saliida ee xeebaha, alaabta tunnelka, alaabta isku dhafka ah, dahaarka godka gantaalada, iyo alaabada kale ee FST la xidhiidha.
Noocyada Isku-dhafka Fiber-Xoojinta ee Phenolic
Isku-dhafka phenolic ee lagu xoojiyay fiber-kawaxaa ka mid ah walxaha lagu wanaajiyey fiilooyinka la jarjaray, dharka, iyo fiilooyinka joogtada ah. Fiilooyinka hore ee la jarjaray (tusaale, alwaax, cellulose) ayaa wali loo isticmaalaa iskudhisyada qaabaynta phenolic ee codsiyo kala duwan, gaar ahaan qaybaha baabuurta sida daboolka bamka biyaha iyo qaybaha is jiid jiid. Iskudhisyada qaabaynta phenolic ee casriga ah waxay ku jiraan fiilooyinka dhalooyinka, fiilooyinka birta, ama dhawaanahan, fiilooyinka kaarboonka. Xabagta phenolic ee loo isticmaalo isku-dhisyada wax-ku-samaynta ayaa ah resins novolac, oo lagu daaweeyay hexamethylenetetramine.
Alaabta dharka ah ee hore loo sii daayay ayaa loo isticmaalaa codsiyo kala duwan, sida RTM (Resin Transfer Molding), qaab-dhismeedka sandwich-ka malabka, ilaalinta ballistic-ga, muraayadaha gudaha ee diyaaradaha, iyo xadhkaha xamuulka. Alaabooyinka xoojiya fiber-ka ee joogtada ah ayaa lagu sameeyaa iyadoo loo maraayo fiilo dabaysha ama pultrusion. Maro iyo joogto ahisku dhafan fiber-xoojiyeyCaadi ahaan isticmaal biyo- ama resins phenolic resole-kaliya. Marka laga soo tago phenolics resole, nidaamyada kale ee la xidhiidha phenolic-sida benzoxazines, cyanate esters, iyo resin-ka cusub ee Calidur™-ayaa sidoo kale ka shaqeeya FRP.
Benzoxazine waa nooc cusub oo resin phenolic ah. Si ka duwan phenolics-dhaqameedka, halkaasoo qaybaha molecular ay ku xiran yihiin buundooyinka methylene [-CH₂-], benzoxazines waxay sameeyaan qaab-dhismeedka wareegtada. Benzoxazines si fudud ayaa looga soo saaray walxaha phenolic (bisphenol ama novolac), amines aasaasiga ah, iyo formaldehyde. Polymerization-furitaankooda ma soo saaraan wax soo saara ama isbeddelaya, taasoo kor u qaadaysa xasilloonida cabbirka alaabta kama dambaysta ah. Marka lagu daro kulaylka sarreeya iyo caabbinta ololka, resins benzoxazine waxay soo bandhigaan guryaha ka maqan phenolics-dhaqameedka, sida nuugista qoyaanka hooseeya iyo waxqabadka dielectric deggan.
Calidur™ waa jiilka soo socda, hal-qayb ka kooban, heerkul-qolka-joogta polyarylether amide thermosetting resin uu sameeyay Evonik Degussa ee hawada iyo warshadaha elektiroonigga ah. Resinku wuxuu ku daaweeyaa 140 ° C 2 saacadood gudahood, oo leh heerkulka kala-guurka galaas (Tg) ee 195 ° C. Waqtigan xaadirka ah, Calidur ™ wuxuu muujinayaa faa'iidooyin badan oo loogu talagalay isku-dhafka waxqabadka sare: ma jiro qiiqa kacsan, falcelinta exothermic hooseeya iyo hoos u dhaca inta lagu jiro daaweynta, kulaylka sare iyo xoogga qoyan, isku-buufin heer sare ah iyo xoog xiirid, iyo adkeysi aad u fiican. Xabagta cusubi waxay u adeegtaa sidii beddelka kharash-oollaha ah ee dhexdhexaad-ilaa-sare-Tg epoxy, bismaleimide, iyo resins cyanate ester ee hawada, gaadiidka, baabuurta, korantada/elektarooniga, iyo codsiyada kale ee dalbanaya.
