Qhov sib txawv ntawm pre-galvanized thiab kub-dip galvanized steel yeeb nkab, yuav ua li cas thiaj kuaj tau nws qhov zoo?

Qhov sib txawv ntawmpre-galvanized yeeb nkabthiabKub-Dip Galvanized Steel Yeeb Nkab

1. Qhov sib txawv hauv cov txheej txheem: kub-dip galvanized yeeb nkab yog galvanized los ntawm impening lub steel yeeb nkab hauv molten zinc, whereaspre-galvanized yeeb nkabyog tusyees coated nrog zinc nyob rau saum npoo ntawm cov steel sawb los ntawm cov txheej txheem electroplating.

2. Cov qauv sib txawv sib txawv: kub-dip galvanized cov yeeb nkab yog lub tubular khoom, thaum lub sij hawm pre-galvanized steel yeeb nkab yog cov khoom sib txawv thiab cov tuab me me.

3. Cov ntawv thov sib txawv: cov kav dej sib txawv yog siv rau kev thauj cov kua thiab roj av, xws li cov khoom siv hlau nplaum, xws li qhov chaw ua lag luam, xws li cov khoom lag luam, hauv tsev Khoom siv plhaub thiab lwm yam.

4. Qhov sib txawv los tiv thaiv corrosion: kub-dip galvanized txheej vim tias cov yas ua kom tuab heev tau ua rau cov txheej txheem tsis zoo vim yog cov txheej galvanized.

5. Cov nqi sib txawv: cov txheej txheem ntau lawm ntawm cov yeeb nkab galvanized yog qhov tseem ceeb thiab cov yeeb nkab ntau lawm ntawm cov yeeb nkab steel yog yooj yim thiab tus nqi qis.

Soj ntsuam ntawm pre-galvanized thiab kub-dip galvanized steel yeeb nkab zoo
1. Pom kev tshuaj xyuas
Nto ua tiav: cov tsos tshuaj xyuas yog feem ntau muaj kev txhawj xeeb nrog rau saum npoo ntawm cov yeeb nkab steel slag, tsis pom zoo zinc slag, txaus dai, ntws mus rau lwm yam. Zoo galvanized steel yeeb nplaim yuav tsum yog du, tsis muaj npuas, tsis muaj cov kab nrib pleb, tsis muaj zinc ntws dai thiab lwm yam tsis xws luag.

Cov xim thiab cov khoom sib txuam: tshuaj xyuas seb cov xim steel yog cov khoom siv hlau yog cov khaub ncaws steel yog cov khoom sib txuam, thiab txawm hais tias muaj cov nqov zinc, tshwj xeeb hauv cov npoo lossis thaj chaw welded. Kub-DIP Galvanized steel yeeb feem ntau tshwm sim silvery dawb lossis off-dawb, thaum pre-galvanized steel yeeb yuav yuav yog sib dua me ntsis hauv cov xim.

2. Zinc Thickness Ntsuas
Thickness koob tso cai: cov tuab ntawm zinc txheej yog ntsuas siv coated thickness gaugness (piv txwv li sib nqus lossis sib nqus lossis eddy tam sim no). Qhov no yog qhov taw qhia tseem ceeb los txiav txim siab yog tias zinc txheej ua tau raws cov qauv. Kub-DIP Galvanized Steel Yeeb Nkab Feem ntau muaj zinc txheej zinc, feem ntau ntawm 60-120 micrvanized steel yeeb muaj ib txheej zinc txheej, feem ntau ntawm 15-30 microns.

Qhov hnyav nyhav (kuaj): Cov qauv yog hnyav raws li tus qauv thiab qhov hnyav ntawm cov zinc txheej ib cheeb tsam yog xam cov tuab ntawm zinc txheej. Qhov no feem ntau yog kev txiav txim los ntsuas ntsuas qhov hnyav ntawm cov yeeb nkab tom qab pickling.

Cov Qauv Yuav Tsum Tau: Piv txwv, GB / T 13912, ASTM A123 thiab lwm yam txheej txheem thickness ntawm cov kav hlau tuab rau cov ntawv thov sib txawv yuav txawv.

3. Kev sib xyaw ntawm Galvanized Txheej
Zoo siab galvanized txheej yog uniform nyob rau hauv kev ntxhib los mos, tsis muaj xaue kev puas tsuaj.

Tsis pom xim liab liab tom qab kuaj cov tooj liab sulfate daws, qhia tau tsis muaj xau lossis tom qab plating puas.

Qhov no yog tus qauv rau cov fittings zoo galvanized fittings kom ua kom muaj kev ua tau zoo thiab tsos.

4. Lub zog nplaum ntawm galvanized txheej
Cov nplaum ntawm Galvanized txheej yog qhov taw qhia tseem ceeb ntawm cov yeeb nkab galvanized, uas qhia txog txheej txheem ntawm galvanized txheej thiab cov yeeb nkab steel.

Cov yeeb nkab steel yuav tsim cov txheej sib xyaw ntawm cov kev daws zinc thiab hlau nrog cov txheej txheem zinc, thiab cov nplaum ntawm cov txheej txheem sciinc tuaj yeem txhim kho los ntawm cov txheej txheem scientific thiab meej galvanizing.

Yog hais tias zinc txheej tsis tau tawm yooj yim thaum tapped nrog cov roj hmab mallet, nws qhia tau zoo adhesion.
