Dhulka hoostiisa, dhuumaha saliidda iyo gaasta ee isdhaafsan waxay u adeegaan sida "xididdada birta" ee qaranka ee gudbinta tamarta. Ka ilaalinta dhuumahaas maalgashiga sare leh ee ka ilaalinaya daxalka ciidda waa hawl injineernimo oo muhiim ah. Mid ka mid ah tignoolajiyada ugu waxtarka badan ee ka hortagga daxalka waa nidaamka ilaalinta cathodic, kaas oo u muuqda mid aan muuqan oo aan laga maarmi karin "ilaaliye aan la arki karin" ayaa door muhiim ah ka ciyaara — looxyada dahaarka fiberglass resin ee epoxy oo ay matalaan FR4, G10/G11.
Waa maxay sababta ay u tahay wax aan laga maarmi karin?
Ilaalinta Cathodic waxay u shaqeysaa iyadoo ku dhejisa qulqul yar oo koronto ah dhuumaha, taasoo u rogi doonta dhammaan qaab dhismeedka cathode si ay asal ahaan u xakameyso daxalka korantada. Shuruudaha ugu muhiimsan ee habkan ayaa ah in la hubiyo in hadda aanu daadan ama aanu gaabin, balse uu si sax ah ugu dhaqmo dhuumaha. Halkan, agabka dahaarka ee waxqabadka sare leh ayaa noqda khadka nolosha ee isku halaynta nidaamka. Iyada oo leh guryaha dahaarka ee aadka u wanaagsan, xoogga farsamada sare, iska caabinta daxalka kiimikaad ee heer sare ah, iyo xasilloonida cabbirka, looxyada dahaarka fiberglass waa kuwo aan la bedeli karin "waa in laga isticmaalo" goobtan.
Falanqaynta Saddexda Xaaladood ee Codsiga Muhiimka ah
1. Xirmooyinka Gaaska Dahaarka Flange - Caqabadaha Dahaarka ee Dhuumaha "Isgoysyada"
Dhuumaha waxaa laga soo ururiyaa qaybo bir ah oo ku xiran garbaha. Dahaarka la'aanteed, taabashada birta ah ee udhaxeysa garabyada waxay sababtaa wareeg gaaban iyo daadinta ilaalinta cathodic ee hadda, si aad ah u yaraynaysa ama xitaa baabi'inaysa saamaynta ilaalinta.
- Codsiga Muhiimka ah: Qalabka dahaarka ee saxan-machined ee ka samaysan looxyada fiberglass-ka ee G10/G11 ayaa lagu rakibay inta u dhaxaysa sagxadaha siman ee flange. Gacmaha dahaarka iyo weelasha ayaa sidoo kale lagu rakibay boolal si ay u sameeyaan "xirmada dahaadhka flange" oo dhamaystiran.
- Shuruudaha Alaabta: Gawaadhidu waa in ay u adkeystaan xoogag adag oo isku xidha iyo culaysyada dhuumaha, iyaga oo iska caabinaaya daxalka kakan ee wakhtiga dheer ee ka imanaya ciidda iyo warbaahinta la gudbiyo. Awoodda farsamada gaarka ah iyo iska caabinta gurguurta ee looxyada G10/G11 waxay dammaanad qaadayaan xidhid iyo dahaar la isku halayn karo muddo tobanaan sano ah.
2. Transformers gudaha - Qaabka dahaadhka ee Awoodda "Wadnaha"
Beddelka toosiye waa "wadnaha" nidaamka ilaalinta cathodic, oo beddelka hadda u beddelaya hadda tooska ah ee looga baahan yahay ilaalinta dhuumaha. Iyada oo koronto sare leh, hadda weyn, iyo qaabka isku dhafan ee gudaha golaha wasiirada, badbaadada dahaarka ayaa muhiim ah.
- Codsiyada Muhiimka ah:
- Qaybaha Dahaarka: Kala saar qaybo koronto oo kala duwan oo leh awoodo kala duwan si looga hortago qulqulka gudaha ama wareegyada gaaban.
- Boodhadhka Dhejinta Terminalka: U adeega sida substrate-ka marinnada hadda-sare ee u baahan caabbinta dahaarka aadka u sarreeya iyo xoogga farsamada si loo hubiyo isku-xirno xasilloon oo aan lahayn wax gurguurta.
- Shuruudaha Alaabta: FR4 loox epoxy, oo leh dahaar koronto oo heer sare ah, dib u dhac ololka (UL94-V0), iyo mashiinnada, ayaa ah doorashada caadiga ah ee qaybahan dahaarka gudaha, ilaalinta amniga iyo xasilloonida hawlgalka qalabka korantada.
3. Saldhigyada Imtixaanka - Saxnaanta "Antennae" ee Nidaamka Kormeerka
Saldhigyada imtixaanku waa calamadaha dhulka oo si siman loogu qaybiyey tubooyinka si loo xaqiijiyo in awooda ilaalintu ay buuxinayso heerarka. Waxay yihiin "daaqadda" tooska ah ee lagu qiimeeyo waxqabadka nidaamyada ilaalinta cathodic.
- Codsiga Muhiimka ah: Looxyada dahaarka fiberglass-ka waxaa loo isticmaalaa sidii taarikada saldhigga dahaarka ee sanduuqyada is-goysyada ee gudaha xarumaha tijaabada. Dhammaan fiilooyinka tijaabada ah ee ka imaanaya dhuumaha waxay ku xiraan terminal ku yaal saxan salkan, iyadoo la hubinayo in calaamadaha cabbirka ay ka go'an yihiin dhulka xogta saxda ah ee dhuumaha.
- Shuruudaha Walxaha: Walxaha waa in ay iska caabiyaan qoyaanka, isbedbedelka heerkulka, iyo daxalka yar ee kiimikaad ee jawiga dibadda, iyaga oo ilaalinaya dahaarka muddada-dheer. Qalabka u adkaysta qoyaanka iyo cimilada u adkaysta ee looxyada fiberglass-ka ayaa si buuxda u buuxiya shuruudahan.
Gabagabo
Laga soo bilaabo mid kasta oo isku xira "wadajir" ee dhuumaha, si ay awood "qalbi" in samatabbixin ilaalinta hadda, in la socodka "anteenada" ku faafay kumanaan miles, epoxy resin fiberglass dahaarka looxs samaynta xannibaad la isku halayn karo oo dhan nidaamka ilaalinta cathodic. In kasta oo aan la qarin karin, haddana waxay soo bandhigaan waxqabad jidheed iyo koronto oo xooggan, iyagoo si aamusnaan ah u xaqiijinaya amniga ka-hortagga daxalka ee boqollaal iyo kun oo kiiloomitir oo tuubooyinka iyo ilaalinta xasilloonida muddada-dheer ee halbowlayaasha tamarta.
Xulashada looxyada fiberglass-ka ee qeexitaan sax ah (sida G10, G11, FR4) maaha oo kaliya go'aan wax iibsiga, laakiin waa doorashada badbaadada injineernimada ee muhiimka ah.
Shirkadeena waxay si qoto dheer ugu hawlan tahay beerista balaastikada injineernimada ee waxqabadka sare leh iyo agabka dahaadhka, waxaana ka go'an inay bixiso xalal wax ku ool ah oo loogu talagalay warshadaha wax soo saarka ee heer caalami. Alaabooyinkayaga ugu muhiimsan waxaa ka mid ah bacaha balaastigga ah ee injineernimada sare sida polyoxymethylene (POM), ABS, nylon (PA), polycarbonate (PC), polyphenylene sulfide (PPS), polyethermide (PEI), polyethertherketone (PEEK), iwm. Iyada oo leh sifooyin aad u fiican sida iska caabin heerkul sarreeya, xirashada iska caabinta, iyo xoog sare, alaabadayada waxaa si weyn loogu isticmaalaa gawaarida tamarta cusub, elektiroonigga smart, mishiinnada warshadaha, hawada hawada iyo meelo kale.
