Ana amfani da takamaiman kayan aiki don takamaiman matakai. Misali, ba za a iya amfani da kayan juriya na galvanized a cikin tsarin electrophoretic ba, wanda zai sa sassan electrophoretic su goge. Yadda za a gano da sauri ko akwai rufi mai haske a saman kayan galvanized shine fasaha mai mahimmanci.
Passivation, juriya na yatsa da sauran hanyoyin bayan magani shine a yi amfani da fim ɗin mara launi da bayyananne a kan ma'aunin galvanized, wanda ke da wahala a gano gani. Akwai hanyoyin gano ƙwararru da yawa, amma gano hanya mai sauƙi da inganci shine burinmu.
Hanyoyin gwaji don gwaje-gwajen sinadarai
1. Binciken ƙa'ida
Ma'anar sawun yatsa ko samfuran juriya na wucewa shine a yi amfani da suturar kwayoyin halitta akan ma'aunin galvanized. Saboda kasancewar rufin, za mu iya samun reagent sinadarai wanda ke amsawa tare da Layer na zinc maimakon rufi, kuma ya bambanta shi bisa ga bambancin saurin amsawa.
2. Gwajin gwaji - 5% maganin sulfate jan karfe
Na gaba, mun ƙaddamar da babban jigon wannan batu: maganin sulfate na jan karfe. Tabbas, idan ƙaddamarwa ba ta da yawa, 5% maida hankali ya isa (marasa launi da m).
3. Ganewa da hukunci
Maganin sulfate na jan karfe zai amsa tare da Layer zinc (Zn + CuSO4 = ZnSO4 + Cu), kamar haka:
Zuba maganin sulfate na jan karfe 5% akan samfurin sawun yatsa mai juriya ko wucewa, sannan a bar shi ya tsaya na mintuna 3, kuma maganin yana nan a bayyane.
Zuba kan takardar galvanized da ba a rufe ba kuma bar shi ya tsaya na minti 3. Maganin yana amsawa tare da Layer na zinc kuma ya juya baki.
lamuran da ke bukatar kulawa
A lokacin aikin na ainihi, dole ne a goge farantin karfe tare da barasa, in ba haka ba sauran man antirust zai jinkirta saurin amsawa.
kwalban bayani, sauke ta digo, mintuna 5, magance duk matsaloli!

Abin da ke sama shine mafi sauƙi na warwarewar ilimi. Na gaba shine ainihin busasshen kaya. Daliban da ba su gama karatu ba ba za su iya more wannan fa'idar ba!
A gaskiya ma, Chaige da kansa ya yi amfani da hanya mafi sauƙi da sauri: hanyar shafa yatsa
Bayan an goge farantin samfurin da tsabta, yi amfani da yatsanka don ƙarfi kuma akai-akai shafa akan saman farantin (tashi, kamar takin shaidan ~ ~).
Yatsun da aka baƙaƙe (tare da faɗuwar foda na zinc) zanen gado ne marasa rufi. Idan babu wani canji na zahiri a saman, yana nuna cewa akwai murfin bayan jiyya.

Wannan hanyar tana buƙatar ɗan gogewa kaɗan, amma yana da arha kuma ya fi dacewa. Menene wurin samarwa yake buƙata? Mai sauri, mai sauki, m!!!
