Akwai nau'ikan bututun ƙarfe maras sumul iri biyu, mai zafi-tsoma galvanizing (zafi-tsoma galvanizing) da galvanizing-tsoma sanyi (electro-galvanizing). Hot-tsoma galvanizing yana da kauri galvanized Layer, wanda yana da abũbuwan amfãni daga uniform rufi, karfi adhesion, da kuma dogon sabis rayuwa. Duk da haka, farashin electro-galvanizing yana da ƙasa, farfajiyar ba ta da santsi sosai, kuma juriya na lalata ya fi na bututun galvanized mai zafi. Yadda za a duba ingancin galvanized karfe bututu?

Dangane da buƙatun ma'auni, mai kera bututun galvanized ya nuna cewa abubuwan dubawa na ma'auni na geometric na bututu maras kyau sun haɗa da kauri bango, diamita na waje, tsayi, curvature, ovality da siffar ƙarshen galvanized bututu mara nauyi.

1. Duba kaurin bango

Kayan aikin da ake amfani da shi don duba kaurin bango galibi micrometer ne. Lokacin dubawa, auna kaurin bangon bututun galvanized ɗaya bayan ɗaya tare da micrometer. Kafin dubawa, da farko tabbatar da ko takardar shaidar micrometer tana cikin lokacin inganci, kuma bincika ko micrometer yana daidaitawa da matsayin sifili kuma ko juyawa yana da sassauƙa. Wurin aunawa ya kamata ya kasance ba tare da tabo da tsatsa ba, kuma ana iya amfani da shi kawai bayan an gama gwajin. Lokacin dubawa, riƙe madaidaicin micrometer da hannun hagu kuma juya dabaran motsa jiki da hannun dama. Ya kamata sandan dunƙule ya yi daidai da diamita na ma'auni, kuma ma'aunin saman ƙarshen bai kamata ya zama ƙasa da maki 6 ba. Idan an gano kaurin bangon bai cancanta ba, sai a yi masa alama.

2. Diamita na waje da duban ovality

Kayan aikin da ake amfani da su don duba diamita na waje da duban ovality sun fi yawa calipers da vernier calipers. Yayin dubawa, auna diamita na waje na bututun galvanized ɗaya bayan ɗaya tare da ƙwararrun caliper. Kafin dubawa, da farko tabbatar da ko takardar shaidar caliper tana cikin lokacin inganci, sannan a bincika caliper da aka yi amfani da shi tare da ma'aunin vernier don ganin ko akwai wani karce ko tsatsa akan saman ma'auni, kuma ana iya amfani da shi kawai bayan wucewa. gwadawa. Lokacin dubawa, caliper ya kamata ya kasance daidai da axis na bututun galvanized, kuma bututun galvanized yana juyawa a hankali. Idan diamita na waje na sashin da aka yi ma'aunin an gano ya yi girma ko ƙanƙanta, ya kamata a yi alama.

3. Tsawon tsayi

Kayan aikin da ake amfani da shi don duba tsawon bututun galvanized maras sumul galibi tef ɗin ƙarfe ne. Lokacin auna tsawon, ma'anar "O" na tef ɗin yana daidaitawa tare da ɗaya ƙarshen bututun galvanized, sa'an nan kuma an ƙara tef ɗin ta yadda ma'auni na tef ɗin yana kusa da farfajiyar bututun galvanized. Tsawon tef a ɗayan ƙarshen bututun galvanized shine tsayin bututun galvanized.

4. Lankwasawa dubawa na galvanized bututu

Binciken digiri na lanƙwasawa na bututun galvanized shine galibi don bincika matakin lanƙwasawa na jimlar tsawon bututun galvanized da matakin lankwasawa kowace mita. Kayan aikin da aka yi amfani da su sun fi mayar da matakin matakin, ma'aunin ji da kuma layin kamun kifi. Lokacin auna jimlar digiri na galvanized bututu, yi amfani da layin kamun kifin don daidaita ƙarshen bututun galvanized, sannan ku matsa layin kifi ta yadda ɗayan layin kamun ya kasance kusa da saman bututun galvanized, sannan yi amfani da ma'auni don auna saman bututun galvanized da kifi. Tazarar tazarar layi, wato, jimlar tsawon bututu maras sumul.

Tukwici: Galvanized yana nufin cewa saman bututun ƙarfe ya yi galvanized, kuma yana iya zama bututun welded ko bututu maras sumul. Wasu bututun karfe ne da aka yi musu walda ta hanyar birgima kai tsaye da zanen gado, wasu kuma an yi su da bututun karfe maras sumul sannan a sanya su.
