Dacromet Flange Bolts: Babban Anti-lalata da Ayyukan Anti-tsatsa don Neman Aikace-aikace 

Dacromet wani tsarin da ba na lantarki ba ne, tsarin rufin ruwa na tushen ruwa wanda ya ƙunshi da farko na tutiya mai rufi da flakes na aluminium wanda aka tarwatsa a cikin abin ɗaure mai chromium mai ɗauke da chromium ko chromium mara amfani. Ana amfani da shi ta hanyar dip-spin, spray, ko tsoma-magudanar hanyoyin kuma daga baya an warke zafi, rufin yana samar da siriri (yawanci 5-15 μm), uniform, fim ɗin kariya mai launin azurfa-launin toka wanda ke manne da madaidaicin karfe.

Tsarin anti-lalata na Dacromet yana aiki ta hanyoyi guda huɗu:

1. Kariyar shinge: Haɗe-haɗe da tutiya da flakes na aluminum suna haifar da yadudduka da yawa waɗanda ke hana shigar danshi, oxygen, da ions masu lalata.

2. Kariyar hadaya (galvanic): Zinc yana aiki azaman anode na hadaya, wanda zai fi dacewa lalata don kare tushen karfe daga tsatsa.

3. Warkar da kai/gyaran kai: Kayayyakin oxidation na zinc da aluminum sun cika ƙananan lahani a cikin rufin, ci gaba da kiyaye amincin tsatsa.

4.Shafi: Mai ɗaure inorganic da mahadi masu wucewa suna jinkirin cin hadaya na zinc, suna tsawaita juriyar lalata gabaɗaya.

Saboda tsarin ba ya haɗa da ɗaukar acid ko electrolysis, rufin Dacromet gaba ɗaya yana kawar da haɗarin haɓakar hydrogen - fa'ida mai mahimmanci ga ƙwanƙwasa ƙarfi (Maki 10.9, 12.9, da ASTM A490 / F3125). Wannan ya sa Dacromet flange bolts duka abin dogaro da injina kuma yana da juriya ga tsatsa da lalata muhalli.

3.1 Na Musamman Lalata da Tsatsa Resistance

Dacromet-rubutun flange bolts suna cimma akai-akai 1,000 hours ko fiye Gwajin gishiri mai tsaka tsaki (ASTM B117 / ISO 9227) ba tare da bayyanar ja ba. A cikin ƙayyadaddun bayanai da yawa, farin tsatsa yana jinkirta sama da sa'o'i 240-500, kuma gabaɗayan aikin rigakafin lalata ya fi sau 7-10 sama da na al'ada electrogalvanizing. Wannan ƙwararren ƙarfin hana tsatsa yana tabbatar da tsawon rayuwar sabis a bakin teku, ruwa, masana'antu, da wuraren yanke ƙanƙara-gishiri.

3.2 Babu Haɗarin Haɗawar Hydrogen

Ba kamar hanyoyin samar da wutar lantarki waɗanda ke gabatar da hydrogen cikin ƙarfe mai ƙarfi ba, tsarin Dacromet dip-spin ko tsarin fesa gabaɗaya ba na lantarki ba ne. Sakamakon haka, ƙusoshin flange masu ƙarfi suna riƙe da cikakkun kayan aikin injiniya kuma suna da 'yanci daga jinkirin karaya da ke haifar da haɓakar hydrogen - yana ba da kariya ta tsatsa da amincin tsari.

3.3 Bakin ciki, Rubutun Uniform tare da Ingantacciyar Sarrafa Girma

Matsakaicin kauri daga 5 zuwa 15 μm. Wannan siririn fim ba ya canza girman zaren da muhimmanci, yana ba da damar yin amfani da daidaitattun kwayoyi ba tare da wuce gona da iri ba. Rufin yana ratsa rikitattun geometries, zaren zaren, da koma baya daidai gwargwado, yana tabbatar da cikakken ɗaukar hoto na hana lalata har ma da ƙayyadaddun bayanan martaba na flange.

3.4 Babban Tsayin Zazzabi da Ƙarin Fa'idodi

Rubutun Dacromet sun kasance masu tasiri a ci gaba da yanayin zafi har zuwa kusan 250-300 ° C, wanda ya zarce iyakokin zafin jiki na al'ada plating na zinc. Ƙarin fa'idodin sun haɗa da kyakkyawan fenti, masu sarrafa juzu'i (musamman tare da manyan riguna masu lubricated), daidaitawar bimetallic tare da aluminium, da bin ƙa'idodin motoci da muhalli da yawa.
