Farqiga iyo codsiga galvanizing, electrophoresis iyo buufinta
Warshadaha farsamaynta birta, habka daaweynta dusha sare waxay si toos ah u saamaysaa wax-qabadka ka-hortagga daxalka, xidhashada caabbinta iyo bilicda. Waxaa jira saddex hab oo lagu daweeyo dusha sare: galvanizing, electrophoresis iyo buufin. Mid kastaa wuxuu leeyahay astaamo u gaar ah waxayna ku habboon yihiin xaaladaha kala duwan ee codsiga. Waxaan is barbardhigi doonaa oo aan falanqeyn doonaa sifooyinka, faa'iidooyinka iyo khasaarooyinka iyo goobaha codsiga ee saddexdan habraac. Xogtu waa tixraac kaliya.
1. Galvanization
Habka Hordhaca
Galvanizing waa geeddi-socod ka hortagaya daxalka iyadoo lagu daboolayo dusha birta lakabka Zinc, inta badan ay ku jiraan galvanizing-kulul iyo galvanizing elektro-galvanizing.
Tilmaamaha ugu muhiimsan
Galvanizing Hot-Dip Galvanizing: Geli badeecada birta xal heerkul sare leh oo zinc ah si aad u samaysato lakab zinc ah oo isku mid ah oogada.
● Dhumucda lakabka Zinc: 50-150μm
● Iska caabbinta daxalka: aad u fiican, oo ku habboon bay'adaha dibadda
● Xaaladda dusha sare: qallafsan, qalin-cawlan, ubaxyo zinc ayaa laga yaabaa inay soo baxaan
Electrogalvanization
Lakabka zinc waxaa lagu shubaa oogada birta iyadoo loo marayo habka korantada si loo sameeyo lakab difaac khafiif ah.
Dhumucda lakabka Zinc: 5-30μm
Iska caabbinta daxalka: Guud ahaan, ku habboon jawi gudaha ah
Xaaladda dusha sare: siman, dhalaal sare
Xaaladaha lagu dabaqi karo
● Galvanization-kulul: qaab dhismeedka buundada,taageerooyinka dhismaha, Taawarrada korontada, dhuumaha dibadda, mishiinada culus, iwm.
● Electrogalvanizing: xirmooyinka yaryar, qaybaha birta gudaha, guryaha qalabka guriga, qaybaha baabuurta, iwm.
Faa'iidada iyo khasaaraha
Faa'iidooyinka: awood xoog leh oo ka-hortagga daxalka, dhaqaale iyo waarta, galvanizing-ku-kulul waxay ku habboon tahay bay'adaha adag
Khasaaraha: Electrogalvanizing wuxuu leeyahay awood daciif ah oo ka-hortagga daxalka, iyo dusha sare ee galvanizing-ku-kulul waa qallafsan yahay, taas oo saameyn karta muuqaalka
2. Dahaarka Electrophoretic
Habka Hordhaca
Dahaarka Electrophoretic waa habka dahaarka isticmaala beer koronto si uu rinjigu si siman ugu dheggan birta. Waxaa si weyn loogu isticmaalaa baabuurta, qalabka guriga iyo warshadaha kale.
Tilmaamaha ugu muhiimsan
● Qaadashada tignoolajiyada anodic ama cathodic electrophoresis, dahaarka waa labbis iyo heerka isticmaalka dahaarka ayaa sarreeya.
● Samaynta daahan organic cufan, oo inta badan loo isticmaalo daawaynta phosphating ama galvanizing si kor loogu qaado waxqabadka ka-hortagga daxalka
● Dhumucda filimka: 15-35μm (la hagaajin karo)
● Midabka: ikhtiyaari (caadi ahaan madow iyo cawl)
Xaaladaha lagu dabaqi karo
● Qaybaha baabuurka (Foom, habka ganaaxa, bireega caliper)
● Qalabka dhismaha (biraha birta ah, xirmooyinka, xirmooyinka tuubooyinka)
● Xadiidka wiishka, qaybaha farsamada
Faa'iidooyinka: daahan labbiska ah, adhesion xooggan, waxqabadka wanaagsan ee ka hortagga daxalka, ilaalinta deegaanka iyo badbaadinta tamarta
Khasaaraha: socodka nidaamka adag, shuruudaha sare ee qalabka, iyo qiimaha bilowga ah ee sarreeya
3. buufin
Habka Hordhaca
Buufintu waxay u qaybsantaa buufinta budada ah (buufinta korantada) iyo buufinta dareeraha ah. Buufinta budada waxay isticmaashaa fal elektrostatic ah si ay budada ugu dhejiso dusha birta oo ay u sameyso daahan iyada oo loo marayo daaweynta heerkulka sare; buufinta dareeraha ah waxay isticmaashaa qori buufin ah si ay si toos ah u buufiso rinjiga, kaas oo ku badan muuqaalada u baahan midabyo qani ah.
Tilmaamaha ugu muhiimsan
buufinta budada:
● Dhumucda dahaarka: 50-200μm
● Xiro aad u fiican oo iska caabin ah iyo iska caabin daxalka, oo ku habboon jawiga dibadda iyo warshadaha
Deegaanka u saaxiib, dareere-free
Rinjiyeynta buufinta dareeraha ah:
● Dhumucda dahaarka: 10-50μm
● Midabo qani ah, oo ku habboon qurxinta wanaagsan
● Dayactirka deegaanka waa la samayn karaa
Xaaladaha lagu dabaqi karo
● buufinta budada: xirmooyinka dhismaha, biraha ilaalinta, guryaha korontada, qalabka dibadda
● Rinjiyeynta dareeraha ah ee buufinta: qalabka guriga ee dhamaadka-sare, alaabta biraha lagu qurxiyo, calaamadaha
Faa'iidooyinka: buufinta budada waxay leedahay dahaar qaro weyn iyo adkeysi wanaagsan; rinjiyeynta buufinta dareeraha ah ayaa leh midabyo qani ah iyo codsiyo badan oo kala duwan
Khasaaraha: buufinta budada ah lama hagaajin karo deegaanka, iyo rinjiyeynta dareeraha ah ee lagu buufiyo ayaa ka yar deegaanka
Soo jeedinta xulashada:
● Waxay u baahan tahay wax qabad aad u xoogan oo ka hortagga daxalka (sida buundooyinka, munaaradaha korontada, dhismooyinka birta wiishka) → Galvanizing kulul
● Waxay u baahan tahay oog siman iyo guud ahaan ka-hortagga daxalka (sida xidhiyaasha, qaybaha baabuurta) → Electrogalvanizing
● Waxay u baahan tahay dahaar isku mid ah iyo iska caabbinta daxalka sare (sida biraha hagaha wiishka, qaybaha baabuurta) → Daahan koronto ah
● Waxay u baahan yihiin iska caabin wanaagsan oo xirashada iyo iska caabinta cimilada (sida xirmooyinka dhismaha, guryaha korontada) → buufinta budada
● Waxay u baahan tahay muuqaal midab leh iyo qurxin wanaagsan (sida qalabka guriga, boodhadhka calaamadaha) → rinjiyeynta buufinta dareeraha ah
Nidaamyo kala duwan ayaa leh astaamo u gaar ah. Doorashada habka saxda ah ee daaweynta dusha sare waxay u baahan tahay in lagu saleeyo deegaanka isticmaalka alaabta, shuruudaha shaqada iyo tixgelinta qiimaha. Xinzhe Metal Products waxay ku siin karaan xalal daawaynta dusha sare ee xirfadeed iyadoo loo eegayo baahida macaamiisha, ku soo dhawoow inaad la tashato!
