Sharaxaada
calaamadeeye
Qeexida alaabta iyo tignoolajiyada xudunta u ah
Gacks-ku dahaadhay zinc-midabaysan ayaa lagu saleeyaa koronto-galvanization si ay u sameeyaan filim passivation midab leh qaanso roobaad (oo ka kooban chromium trivalent ama chromium hexavalent) oo dhumucdiisuna tahay filim qiyaastii 0.5-1μm. Wax qabadkeeda ka-hortagga daxalka ayaa si weyn uga wanaagsan electrogalvanizing caadiga ah, iyo midabka dusha sare waa dhalaalaya, oo leh shaqeyn iyo qurxiyo labadaba.
Qalabka muhiimka ah iyo sifooyinka
Qalab: Q235 birta kaarboon, Q345 aluminium bir ah, adkaanta substrate HV150-250.
Astaamaha:
Iska caabbinta daxalka sare: Ma jiro miridh cad oo ku jira tijaabada buufinta cusbada dhexdhexaadka ah ee saacadaha 72-120, oo ku habboon jawiga bannaanka ama qoyan;
Awoodda dib-u-dayactirka: Ka dib marka la xoqo filimka passivation, qaybta chromium hexavalent waxay si toos ah u hagaajin kartaa meesha dhaawacan;
Aqoonsiga midabka: Midabada qaanso roobaadyada waxaa loo isticmaali karaa in lagu kala saaro heerar kala duwanaansho ama dufcooyin (sida warshadaha korontada).
Shaqada iyo xaaladaha lagu dabaqi karo
Shaqada:
U adkaysta daxalka sida buufinta milixda iyo roobka aashitada muddo dheer, oo leh nolol adeeg 3-5 jeer tan zinc electroplating caadiga ah;
Aqoonsiga muuqaalka oo la xoojiyay, dayactirka qalabka fudud iyo maaraynta.
Muuqaal:
Qalabka korantada ee dibadda (sida bolts taawar), injineernimada badda (isku xirka sagxada markabka), mishiinada kiimikada (flange taangiga).
Rakibaadda iyo dayactirka
Rakibaadda:
Furaha qulqulka waa in la isticmaalaa si loo hubiyo in la diyaariyo labbiska si looga hortago in filimka baabuurka uu ka dhaco kaxaynta xad dhaafka ah awgeed;
Xiriirka tooska ah ee biraha firfircoon sida aluminium iyo magnesium waa mamnuuc si looga hortago daxalka galvanic.
Dayactirka:
Iska ilaali isticmaalka nadiifiyeyaasha acidic, waxaa lagu talinayaa in lagu tirtiro dareerayaasha dhexdhexaadka ah;
Gacksivation chromium hexavalent waa in ay u hoggaansamaan xeerarka deegaanka (sida xeerarka EU REACH), iyo gaasaska baasaska-free-chromium-ka ayaa aad ugu habboon warshadaha cuntada iyo dawooyinka.
Iibka talooyinka
Xaalado leh shuruudo deegaan oo sarreeya, dooro passivation chromium trivalent ama hababka baas-beelka-chromium-free;
Si taxaddar leh u isticmaal gaasaska zinc-ga midabka leh ee heerkulka sare leh (> 100 ℃), maadaama laga yaabo in filimka bakhtiyayaashu uu qudhmo oo uu guuldareysto.
