Dubawa na pre-galvanized da zafi-tsoma galvanized karfe bututu ingancin
1. Duban bayyanar
Ƙarshen saman: Binciken bayyanar ya fi damuwa da ko saman bututun ƙarfe yana da faɗi da santsi, ba tare da bayyanannen slag na zinc ba, ƙwayar zinc, rataye kwarara ko wasu lahani na saman. Kyakkyawan galvanized karfe bututu surface ya zama santsi, babu kumfa, babu fasa, babu tutiya ciwace-ciwacen daji ko tutiya kwarara rataye da sauran lahani.

Launi da daidaito: Bincika ko launi na bututun karfe daidai ne kuma daidai ne, da kuma ko akwai rashin daidaituwa na rarraba Layer na zinc, musamman a wuraren kabu ko welded. Hot-tsoma galvanized karfe bututu gaba daya bayyana silvery fari ko kashe-fari, yayin da pre-galvanized karfe bututu iya zama dan kadan haske a launi.

2. Zinc kauri ma'auni
Ma'aunin Kauri: Ana auna kauri na Layer zinc ta amfani da ma'aunin kauri mai rufi (misali Magnetic ko eddy current). Wannan alama ce mai mahimmanci don ƙayyade idan murfin zinc ya dace da daidaitattun buƙatun. Bututun ƙarfe mai zafi mai zafi yana da kauri mai kauri, yawanci tsakanin 60-120 microns, kuma bututun ƙarfe da aka riga aka girka yana da ɗan ƙaramin zinc Layer, yawanci tsakanin 15-30 microns.

Hanyar nauyi (samfurin): Ana auna samfuran bisa ga ma'auni kuma ana ƙididdige nauyin ma'aunin zinc a kowane yanki don sanin kauri na Layer zinc. Yawancin lokaci ana ƙididdige wannan ta hanyar auna nauyin bututun bayan tsinke.

Standarda'idodin: Misali, GB/T 13912, ASTM A123 da sauran ka'idoji suna da buƙatu bayyanannu don kauri daga cikin tutiya Layer, kuma buƙatun kauri na tutiya don bututun ƙarfe don aikace-aikacen daban-daban na iya bambanta.

3. Uniformity na galvanized Layer
High quality galvanized Layer ne uniform a cikin rubutu, babu yayyo kuma babu post plating lalacewa.

Ba a samun jajayen mashi bayan gwaji tare da maganin sulfate na jan karfe, wanda ke nuni da cewa babu yabo ko lalacewa bayan plating.

Wannan shine ma'auni don ingantaccen kayan aikin galvanized don tabbatar da ingantaccen aiki da bayyanar.

4. Ƙarfin mannewa na galvanized Layer
Ƙimar da aka yi da galvanized Layer alama ce mai mahimmanci na ingancin bututun ƙarfe na galvanized, wanda ke nuna matakin ƙarfi na haɗin gwiwa tsakanin galvanized Layer da bututun ƙarfe.

Bututun karfe zai samar da cakudaccen tutiya da baƙin ƙarfe tare da maganin galvanizing bayan amsawar dipping bath, kuma mannewar Layer na zinc na iya haɓaka ta hanyar kimiyya da daidaitaccen tsarin galvanizing.

Idan Layer na zinc ba ya fita cikin sauƙi lokacin da aka taɓa shi da mallet na roba, yana nuna kyakkyawan mannewa.
