Lub lauj kaub hlau yog cov khoom siv zinc/aluminium yog li koj ua tsis muaj lauj kaub hlau . Tsuas yog tsis- sib nqus koj yuav khiav mus rau qhov uas yuav tsis meej pem yog stainless hlau . Stainless hlau yog tsis sib nqus , qaug zog sib nqus feem ntau.

Ib yam nkaus, koj yuav qhia tau li cas tias lub lauj kaub yog hlau?

Yog koj muaj tseeb lauj kaub hlau uas yog zinc ntau, ces koj tuaj yeem ua kom sov thiab saib cov xim ntawm cov pa luam yeeb. Yog hais tias nws yog dawb, ces nws yog lauj kaub hlau . Koj kuj tseem tuaj yeem ua tau qhia vim lauj kaub hlau melting kub yog zoo nkauj tsawg nyob rau hauv kev sib piv rau cov ntawm lwm yam hlau . Koj tseem tuaj yeem ntsuas qhov ntsuas hlau.

Tsis tas li ntawd, cov hlau nplaum puas yuav lo rau cam khwb cia hlau? Hauv lawv lub xeev ntuj, cov hlau xws li tooj dag, tooj liab, kub thiab nyiaj yuav tsis nyiam hlau nplaum . Qhov no yog vim lawv tsis muaj zog hlau pib nrog. Magnets tsuas yog txuas lawv tus kheej rau cov hlau muaj zog xws li hlau thiab cobalt thiab yog vim li cas tsis yog txhua hom hlau ua tau ua hlau nplaum nplaum rau lawv.

Hauv qhov no, lub lauj kaub hlau yog dab tsi?

Thawj feem ntawm lauj kaub hlau yog zinc, tab sis feem ntau lub caster ntxiv lwm yam hlau mus rau qhov sib tov kom ntxiv dag zog rau qhov cam khwb cia, txhim kho ntws ntawm molten hlau , los yog txo tus nqi. Nrog rau qhov qis melting point ntawm 420 ° C (786 ° F), zinc feem ntau alloyed nrog lwm yam hlau suav nrog txhuas, tin, aluminium, thiab tooj liab.

Dab tsi yog hlau yog hlau nplaum?

Cov hlau feem ntau siv rau cov hlau nplaum ruaj khov yog hlau , npib tsib xee , cobalt thiab qee cov alloys ntawm cov hlau tsis tshua muaj hauv ntiaj teb. Muaj ob hom hlau nplaum ruaj khov: cov uas los ntawm "nyuaj" sib nqus cov ntaub ntawv thiab cov los ntawm "mos" magnetic cov ntaub ntawv . "Hard" sib nqus hlau zoo li nyob ruaj khov nyob rau lub sijhawm ntev.
