Kuleyl-kulul galvanized boolal: Ilaaliyeyaasha aan muuqan ee qalabka warshadaha

Nidaamka wax soo saarka warshadaha casriga ah, eeboolsida isku xirka farsamada aasaasiga ah ee aasaasiga ah, waxqabadkeedu wuxuu si toos ah u saameeyaa isku halaynta iyo badbaadada nidaamka qalabka oo dhan.Iyadoo boolal-dhaqameedka birta kaarboonka ah ay daxaleeyaan heerka 0.03-0.15mm sanadkiiba jawiga qoyan, boolal-kulul-kululku waxay muujinayaan adkeysi aad u wanaagsan jawiga adag sida qalabka kiimikada, meelaha xeebaha ah, iyo munaaradaha gudbinta oo leh astaamo ilaalineed oo gaar ah.Habka daaweynta dusha sare ma aha oo kaliya inuu kordhiyo nolosha adeegga xirmooyinka, laakiin sidoo kale wuxuu door muhiim ah ka ciyaaraa goobta badbaadada warshadaha.

1. Horumarka cusub ee ilaalinta birta

Geedi socodka galvanizing kuleyl kulul, qaybaha birta waxaa lagu rusheeyaa dareeraha zinc la dhalaaliyay ee 450 ℃, iyo qaababka ilaalinta lakabyada badan ayaa lagu sameeyay iyada oo loo marayo falcelinta daawaynta birta-zinc.Dhumucda lakabka zinc saafiga ah ee ka sameysan dusha sare wuxuu gaari karaa 60-80μm, oo aad uga badan 5-15μm ee galvanizing koronto.Hantidan biraha ku xidhani waxay awood u siinaysaa daahan inuu yeesho xabag dhan 4000-6000psi mana ka dhacayo xataa haddii is jiid jiid dusha ahi dhaco inta lagu guda jiro isku-xidhka boodhka.Habka ilaalinta anode-ka allabariga ee zinc wuxuu sii wadaa inuu door ku yeesho daahan dhaawacan, wuxuu doorbidayaa inuu isticmaalo zinc iyada oo loo marayo daxalka korantada, wuxuuna si wax ku ool ah u daahiyaa habka daxalka ee birta matrixka.

Mashruuca dhismaha buundada badda isku-tallaabta, boolasha caadiga ah waxay u muuqdaan miridh cas oo cad oo ku jira jawiga jawiga badda muddo 6 bilood ah, halka boolal-kuleelka galvanized-ku ay sii jiraan muddo ka badan 5 sano isla xaalado isku mid ah.Saamaynta ilaalintani waxay sidoo kale muhiim u tahay jawiga warshadaha ee baaruudku ka kooban yahay, iyo iska caabinta lakabka zinc ee kulul ee H2S, SO2 iyo gaasaska kale ee daxalka ah ayaa ka badan 3 jeer ka mid ah daaha caadiga ah.

Marka la barbardhigo dahaarka dacromet, galvanizing-ku-kululku wuxuu leeyahay faa'iidooyin muuqda oo iska caabin ah burburka farsamada.Xoog-xiirashada torque ee ay abuuraan boolal inta lagu jiro rakibidda waxay sababtaa dildilaaca yar yar ee daahanka dacromet, halka lakabka galvanizing-ku-kululku uu yahay mid sax ah iyada oo ay ugu wacan tahay sifooyinka isku-xidhka biraha.Xaaladaha gariirka, nolosha ilaalinta ee boolal-kulul-kululku waxay gaari karaan 2-3 jeer marka loo eego daaweynta dacromet.

2. Laba jeer dammaanad qaadka badbaadada qaabdhismeedka

Qalabka farsamada ee boolalku waxay wanaajiyeen galvanization-ku-kulul ayaa dhaaftay filashooyinka.Samaynta lakabka daawaynta zinc-iron waxay kordhisaa adkaanta dusha sare ilaa 250-300HV, taas oo u dhiganta 1.5 jeer adkaanta substrate-ka.Tijaabada gariirka isdhaafka ah ee boolal qeexida M24, daawaynta galvanizing kulul waxay hagaajisay waxqabadka ka-hortagga dabacsanaanta qiyaastii 30%, iyada oo ay ugu wacan tahay hagaajinta isku-dhafka isku-dhafka ah ee daahan.Kala duwanaanshaha isku-dhafka isku-dhafka ah ee lakabka galvanizing waa 0.06-0.10, taas oo ka dhigaysa xakamaynta horudhaca mid sax ah oo la isku halayn karo.

Waxqabadku si gaar ah ayuu ugu fiican yahay jawiga heerkulka sare.Marka heerkulka hawlgalka uu gaaro 300 ℃, lakabka qulqulaya galvanizing kulul wuxuu bilaabaa inuu maro faafin adag wuxuuna si tartiib tartiib ah isu beddelaa qaab dhismeed cufan.Unugga dildilaaca kicinta ee shirkadda batroolka ayaa adeegsataboolal galvanized kulul-muquufin. Ka dib 30,000 saacadood oo hawlgal joogto ah oo ah 380 ℃, haynta qulqulka ayaa wali ka sarraysa 85%, taas oo aad uga badan heerka haynta 50% ee boolal caadi ah.

Waxqabadkeeda xaaladaha culeyska xad dhaafka ah waxay xaqiijineysaa isku halaynta.Tijaabada isku xidhka daalka buufinta milixda ee 10.9 boolal xoog sare ah ayaa tusinaya in nolosha daalka ee galvanizing-ku-kulul la kordhiyey 40%.Ilaalinta cathodic ee lakabka zinc waxay si wax ku ool ah u joojisaa bilawga dildilaaca daxalka, taas oo muujinaysa faa'iidooyinka gaarka ah ee jawiga culeyska firfircoon.

3. Kacaanka waxtarka leh ee dayactirka warshadaha

Falanqaynta kharashka wareegga nolosha ee buuxa waxay muujineysaa in galvanization-ku-kululku uu kordho kharashyada bilowga ah 15%-20%, laakiin waxay kordhisaa wareegyada dayactirka min 2 sano ilaa in ka badan 10 sano.Ka dib markii biraha isku xirka tuubada taawar ee beerta dabaysha loo rogo galvanizing kulul, kharashka dayactirka sanadlaha ah ayaa la dhimay 70%, iyo kharashka qaadista ee la badbaadiyay 20-kii sano ee nolosha adeegga ayaa ka badan 5 jeer maalgashigii hore.Faa'iidada qiimahan ayaa si gaar ah muhiim ugu ah kaabayaasha waaweyn.

Faa'iidooyinka deegaanka sidoo kale lama iska indho tiri karo.Heerka isticmaalka zinc ee geeddi-socodka galvanization-kuleelka kulul ayaa ka badan 98%, taas oo aad uga sareysa 60% daahan dacromet.Daawaynta ka xorta ah Chromium waxay ka fogaataa wasakhaynta birta culus, iyo nidaamyada soo kabashada uumiga zinc waxay sii daayaan ka hooseeya 5mg/m³.Isticmaalka tamarta ee habka oo dhan waa 30% ka hooseeya kan buufinta budada ah, taas oo la socota isbeddelka horumarinta ee wax soo saarka cagaaran.

Goobta tamarta cusub, ka dib markii nidaamka bracket-ka sawir-qaadista uu isticmaalo boolal-kulul-kulul galvanized, looma baahna in lagu beddelo inta lagu jiro muddada 25-sano ee dammaanadda.Xogta isbarbardhigga ah ee mashruuca sawir-qaadista ee xeebaha badda waxay muujineysaa in heerka qudhunka sanadlaha ah ee nidaamka taageerada iyadoo la adeegsanayo xirmooyinka galvanized-ku-kulul kaliya waa 0.5%, taas oo 50% ka aamin badan habka daaweynta dhaqameed.

Horumarka tignoolajiyada warshadaha ayaa inta badan ka muuqda hal-abuurka qaybaha aasaasiga ah.Iyada oo loo marayo horumarka injineernimada dusha shay, heerka ilaalinta ee xirayaasha caadiga ah ayaa kor loo qaaday meel cusub.Hal-abuurnimadan tignoolajiyadeed kaliya ma xalliso dhibaatada daxalka ee fashilka dhaqankaboolal, laakiin sidoo kale kor u horumarinta qalabka warshadaha in muddo dheer iyo dayactirka-free jihada.Iyadoo horumarinta joogtada ah ee shuruudaha isku halaynta qalabka ee wax-soo-saarka caqliga leh, tignoolajiyada galvanizing-kululku waxay hubaal ahaan muujin doontaa qiimaha aan la bedeli karin ee meelo badan oo muhiim ah.
