Birta kaarboon DIN6923 hexagon flange ilig saxan fidsan

Waa maxay galvanization-ku-kulul?

Galvanizing-kululku waa hab caadi ah oo lagu daboolo dusha birta leh lakabka zinc, ujeedada ugu weyn ee taas oo ahka hortagga oxidation birta iyo daxalka.

Galvanizing-ku-kulul waa in la geliyo birta birta ah ee dareeraha la dhalaaliyay ee zinc si loo sameeyo lakab difaac ah. Habka gaarka ah waa sida soo socota:

Daawaynta ka hor:
Hoos u dhigidKa saar waxyaabaha wasakhaysan sida saliidda, boodhka, iwm. ee dusha birta ah, guud ahaan adigoo isticmaalaya xalalka alkaline si loo nadiifiyo.
QaadisIsticmaal aashitada hydrochloric ama sulfuric acid si aad uga saarto miisaanka oksaydhka iyo miridhka dushiisa birta si aad u hubiso inay nadiif tahay.
Biyo dhaqid: Ka saar walxaha aashitada leh ee ku haray habka wax-soo-saarka si aad uga fogaato inay saameeyaan hababka xiga.
Daawaynta gargaarka dhejinta: Ku dhex quusi ​​qalabka wax lagu dhejiyo (sida xalalka zinc chloride) si aad u sameysid filim khafiif ah oo khafiif ah si aad uga ilaaliso dusha birta inay mar kale oksijiinta ka hor inta aan la kicin oo wanaajiso adhesion zinc.

Galvanization-kulul:
Geli qaybta shaqada ee la sii daayay ee la dhalaaliyay ee zinc ah ilaa 450 ° C si aad zinc ula falgasho matrixka birta si aad u samayso lakabka daawaha zinc-iron iyo lakab zinc saafi ah.

Qaboojin:
Ka saar qalabka shaqada ee dareeraha zinc, oo ku qabooji hawo ama biyo si aad lakabka zinc uga dhigto mid dhaqso leh u adkeyso oo u sameeyo lakab difaac isku mid ah.

daawaynta ka dib:
Mararka qaarkood daawaynta passivation ayaa loo baahan yahay si looga hortago miridhku cad ee dusha sare ee lakabka galvanized.
Dhameystir dusha shaqada, sida ka saarida qanjidhada zinc ee xad-dhaafka ah, burrs, iwm.

Kormeerka tayada:
Hubi dhumucda, ku dheggan, muuqaalka, iwm ee lakabka galvanized si loo hubiyo in tayada galvanizing ee workpiece la kulmo heerka.

Astaamaha galvanizing-ku-kulul: lakabka zinc waa ka dhumuc weyn yahay oo leeyahayiska caabin daxalka xooggan, kaas oo ku habboonisticmaalka dibadda ee muddada dheer, laakiin dusha ayaa ka sii qallafsan, muuqaalkuna wuu ka yara daran yahay.

Alaabooyinka lagu daweeyo galvanizing kulul ayaa si weyn loogu isticmaalaa qalabka sida dhismaha, gaadiidka, korontada, warshadaha tamarta, mashiinada iyo qalabka culus, daaweynta biyaha iyo tas-hiilaadka deegaanka, wax soo saarka baabuurta, beeraha iyo ranch, iwm Tusaale ahaan, in ulaha wiishka:biraha wiishka, xadiidka xadiidka, xadhkaha fiilada iyo xidhmooyinka,saxanka isku xirka xadiidka hagaha, Qaab dhismeedka birta usheeda dhexe, ilaaliyaha iyo qalabka badbaadada, qiiqa iyo nalalka qalabka biraha, xidhayaasha (boolal, nuts) sidoo kale waxay u baahan tahay galvanization-ku-kulul.
