Hauv phau ntawv qhia no, peb yuav rhuav tshem vim li cas tooj liab screws tsis sib nqus, debunk ib qho lus dab neeg, tshawb nrhiav cov ntawv tseem ceeb ntawm lawv qhov tsis yog -sib nqus qhov sib nqus, thiab qhia tias JOYEAR cov khoom ua kom zoo tshaj plaws li cas. Thaum kawg, koj yuav muaj kev ntseeg siab tag nrho ntawm cov ntsia hlau tooj liab 'tsis yog- kev ntseeg tau sib nqus- thiab vim li cas kev koom tes nrog JOYEAR lav kev ua haujlwm txawm tias qhov chaw muaj kev cuam tshuam loj tshaj plaws.

1. Kev Tshawb Fawb: Vim li cas tooj liab Screws tsis sib nqus

Txhawm rau teb "Puas yog tooj liab ntsia hlau sib nqus?", peb xub qhib lub physics ntawm hlau nplaum thiab nws cuam tshuam li cas rau tooj liab lub atomic qauv:

1.1 Dab tsi ua rau Hlau Sib Nqus?

Magnetism tshwm sim los ntawm kev sib tw ntawmunpaired electronsnyob rau hauv cov hlau atoms. ferromagnetic cov ntaub ntawv (xws li hlau, hlau, npib tsib xee) muaj unpaired electrons uas yooj yim dlhos nrog lwm magnetic teb, tsim ib tug muaj zog txaus nyiam. Tsis yog- cov ntaub ntawv sib nqus, los ntawm qhov sib txawv, tsis muaj cov khoom siv hluav taws xob tsis sib xws- lossis lawv cov hluav taws xob sib txawv tshem tawm ib leeg tawm - tiv thaiv kev sib txuam nrog cov hlau nplaum.

1.2 Copper's Atomic Structure: Tsis muaj Electrons Unpaired=Tsis muaj Magnetism

Ntshiab tooj liab (Cim cim Cu, atomic tooj 29) muaj antsej muag -centered cubic (FCC) atomic qauvnrog tag nrho cov electrons ua ke. Nov yog vim li cas qhov no tseem ceeb:

• Txhua lub atom tooj liab muaj 29 electrons, teem rau hauv lub plhaub. Lub plhaub sab nraud (valence plhaub) muaj 1 electron, tab sis nyob rau hauv cov khoom tooj liab, cov valence electrons tau muab faib ua "hiav txwv ntawm electrons" (metallic bonding)- txhais tau tias tsis muaj ib qho atom muaj ib qho hluav taws xob tsis sib xws.
• Yog tias tsis muaj cov khoom siv hluav taws xob tsis sib xws, tooj liab tsis tuaj yeem ua raws li cov khoom sib nqus. Nws raug cais raws lidiamagnetic, lub ntsiab lus nws tsis muaj zog tiv thaiv magnetic teb (ib qho quab yuam kom faint nws yog undetectable nrog standard hlau nplaum).

1.3 Magnetic vs. Non-Magnetic Fasteners: Kev sib piv ceev

Txhawm rau muab qhov no rau hauv cov ntsiab lus, ntawm no yog yuav ua li cas tooj liab ntsia hlau sib nqus sib nqus thiab lwm yam tsis yog - cov hlau nplaum sib nqus:

JOYEAR pab pawg tswj xyuas kev ua tau zoo siv qhov kev tshawb fawb no: txhua pawg ntawmtooj liab alloy precision stamping qhov chawundergoes magnetic test nrog neodymium hlau nplaum los xyuas kom meej xoom attraction. Qhov no yog qhov tseem ceeb rau cov neeg siv khoom hauv kev kho mob thiab kev lag luam aerospace, qhov twg txawm tias cov kab hlau nplaum tuaj yeem cuam tshuam cov cuab yeej lossis cuam tshuam kev nyab xeeb.

2. Cov lus dab neeg: Thaum tib neeg xav tias cov ntsia hlau tooj liab yog hlau nplaum

Txawm hais tias muaj kev tshawb fawb, kev xav tsis zoo txuas ntxiv txog tooj liab ntsia hlau hlau nplaum. Nov yog cov lus dab neeg uas nquag nquag tshaj plaws -thiab yog vim li cas lawv dag:

2.1 Myth: "Copper Alloys (Brass / Bronze) Yog Sib Nqus"

False-tus qauv tooj dag (60–70% tooj liab + 30-40% zinc) thiab tooj liab (tooj liab + tin) tsis yog-sib nqus. Zoo li tooj liab ntshiab, lawv cov qauv atomic tsis muaj cov khoom siv hluav taws xob tsis sib xws. Qhov tsis meej pem feem ntau tshwm sim los ntawmqis- zoo tooj dag/bronze nrog hlau impurities(piv txwv li, pheej yig kho vajtse tov nrog hlau). Cov hlau tsis huv no tuaj yeem nyiam cov hlau nplaum tsis muaj zog-tab sis lawv tsis yog cov hlau nplaum tiag tiag.

JOYEAR zam qhov no los ntawm kev nrhiav cov khoom siab -purity tooj liab rau lawv cov alloys thiab ua spectrometer tsom xam kom tshem tawm cov kab mob hlau. Lawv cov tooj dag- cov khoom sib xws (siv nrog tooj liab screws hauv marine daim ntaub ntawv) yog 100% tsis yog-magnetic, raws li kev txheeb xyuas los ntawm - tsev kuaj.

2.2 Myth: "Old lossis tarnished tooj liab ntswj ua hlau nplaum"

False-tarnish (tooj liab oxide) yog ib txheej nyias ntawm corrosion uas ua rau tooj liab nto thaum raug oxygen thiab ya raws. Nws hloov cov ntsia hlau zoo li (los ntawm reddish-txiv kab ntxwv mus rau tsaus xim av los yog ntsuab) tab sis tsis hloov nws cov qauv atomic. tarnished tooj liab tseem tsis yog -magnetic- tsuas yog qhov chaw chemistry hloov, tsis yog electron khub.

2.3 Lus dab neeg: "Ib lub zog Neodymium hlau nplaum yuav lo rau tooj liab"

False-txawm tias muaj zog neodymium hlau nplaum (cov hlau nplaum uas muaj zog tshaj plaws) yuav tsis lo rau cov tooj liab dawb. Koj tuaj yeem pom qhov hloov maj mam "dag" yog tias koj tso cov hlau nplaum hauv cov yeeb nkab tooj liab (vimeddy dej ntws, cov nyhuv electromagnetic induction), tab sis qhov no tsis yog attraction - nws yog ib ntus tiv thaiv los ntawm cov hlau nplaum lub zog, tsis sib nqus adhesion. Cov hlau nplaum yuav tsis khi rau ntawm tooj liab.

2.4 Myth: "Cov Ntsia Hlau Hlau rau Kev Siv Hluav Taws Xob yog Sib Nqus"

False-industrial-qib tooj liab screws (xws li cov khoom siv hauv hluav taws xob, kav dej, lossis aerospace) yog tsim los ntawm cov tooj liab ntshiab lossis siab- tooj liab alloys (xws li, C11000 electrolytic tawv pitch tooj liab). Cov ntaub ntawv no yog txhob txwm tsim los ua tsis yog -magnetic. Sib nqus "tooj liab" cov ntsia hlau yuav luag txhua zaus yog cuav lossis tsis raug (xws li, tooj liab-plated steel).

JOYEAR qhia cov neeg siv khoom kom kuaj cov neeg xav tias cov ntsia hlau tooj liab nrog cov hlau nplaum- yog tias nws lo, cov khoom tsis yog tooj liab dawb. Lawv tus kheej cov ntsia hlau tooj liab thiab cov khoom siv ntxiv (piv txwv li, PCB vuam terminals) tau lees tias tsis yog- sib nqus, nrog cov ntaub ntawv pov thawj los ua pov thawj purity.
