Thaum ua hauj lwm nrog cov ntaub ntawv tooj liab -txawm yog cov kav dej, cov khoom siv hluav taws xob, lossis cov khoom siv vaj tsev tsim vaj tsev - lo lus nug "Yuav ua li cas hom screws kuv siv tau nrog tooj liab?" Nws yog ib qho tseem ceeb rau kev tiv thaiv corrosion, ua kom ruaj khov, thiab tswj kev ua haujlwm. Tus yuam sij rau compatibility yog nyob rau hauvminimizing galvanic corrosion(qhov nrawm nrawm tshwm sim los ntawm cov hlau sib txawv ntawm qhov sib txawv ntawm qhov chaw ntub dej) thiab sib piv cov khoom siv kho tshuab. Qhov zoo tshaj plaws screws rau tooj liab yogtooj liab ntsia hlau, tooj dag screws, stainless hlau screws (304/316), thiab titanium screws-tag nrho nrog electrode muaj peev xwm ze rau tooj liab, tiv thaiv kev puas tsuaj tshuaj lom neeg.

Hauv phau ntawv qhia no, peb yuav rhuav tshem cov ntsia hlau tshaj plaws rau tooj liab, piav qhia vim li cas galvanic corrosion tseem ceeb, thiab qhia tias JOYEAR txoj kev txawj ntse txhim kho kev sib raug zoo li cas. Thaum kawg, koj yuav paub tseeb tias cov ntsia hlau twg los ua ke nrog tooj liab- thiab vim li cas kev koom tes nrog JOYEAR ua kom cov txiaj ntsig zoo.
1. Kev Tshawb Fawb Txog Kev Sib Raug Zoo: Tsis txhob Galvanic Corrosion
Yuav kom nkag siab txog cov ntsia hlau twg ua haujlwm nrog tooj liab, peb ua ntej piav qhia galvanic corrosion- qhov kev pheej hmoo loj tshaj plaws ntawm kev siv cov hlau tsis sib xws:
1.1 Galvanic Corrosion ua haujlwm li cas
Thaum ob qhov sib txawv ntawm cov hlau sib txawv ntawm qhov sib txawv ntawm cov dej noo (ib qho electrolyte), cov ntaub ntawv hluav taws xob tam sim no. Cov hlau "tsawg noble" (tsawg dua electrode muaj peev xwm) corrodes sai heev los tiv thaiv cov "ntau noble" hlau (muaj peev xwm ntau dua).
- Tooj liab muaj peev xwm ua tau zoo electrode (+0.34 V vs. standard hydrogen electrode).
- Cov hlau uas muaj peev xwm sib txawv heev (xws li steel: -0.44 V) yuav ua rau tooj liab corrode qeeb, tab sis cov ntsia hlau yuav xeb heev.
- Cov hlau uas muaj peev xwm zoo sib xws (piv txwv li, tooj dag: +0.30 V; stainless hlau 316: +0.20 V) txo qis tam sim no, tsis txhob muaj qhov cuam tshuam loj heev.
1.2 Vim li cas Qhov no tseem ceeb rau kev siv tooj liab
Galvanic corrosion tuaj yeem:
- Ua kom cov kav dej tooj liab tawg (txog) lossis cov khoom siv hluav taws xob (tsis muaj conductivity).
- Txo lub neej ntev ntawm fasteners, ua rau xoob kev sib txuas los yog kev ua haujlwm tsis zoo.
- Ua kom cov nqi kho mob ntxiv-JOYEAR cov neeg siv khoom qhia txog 40–60% txo tus nqi hloov pauv thaum siv cov ntsia hlau sib xws.
JOYEAR txoj kev tswj xyuas zoo ua raws li kev tshawb fawb no: lawv cov khoom siv tooj liab tau dhau los ntawm 500+ teev ntawm kev tshuaj ntsuam ntsev ntsev (ISO 9227) txhawm rau txheeb xyuas qhov sib haum nrog cov lus pom zoo.

3.3 Aluminium Screws
- Electrode muaj peev xwm (-1.66 V) ua rau muaj kev puas tsuaj corrosion ntawm txhuas thiab tooj liab.
- Risk: Aluminium screws disintegrate nyob rau hauv lub hlis, ua rau tooj liab Cheebtsam xoob los yog puas.
JOYEAR tus ua ntej- pab pawg muag khoom qhia cov neeg siv khoom kom tsis txhob muaj cov ntsia hlau no, es tsis txhob pom zoo cov kev xaiv sib xws raws li daim ntawv thov thiab ib puag ncig.
4. Cov lus qhia kev teeb tsa rau cov ntsia hlau sib xws & tooj liab
Txawm tias txoj cai screws yuav ua tsis tau yog tias ntsia tsis raug - ua raws li cov lus qhia no kom ua tau zoo tshaj plaws:
4.1 Siv Tsis yog-Cov tshuab ntxhua khaub ncaws (Rau cov hlau tsis sib xws)
Thaum sib txuas cov tooj liab nrog cov hlau tsis muaj steel lossis titanium screws (qhov txawv me ntsis), siv cov yas los yog roj hmab ntxhua kom cais cov hlau -txo cov galvanic corrosion.
4.2 Tsis txhob dhau -Tightening
tooj liab yog zas - dhau- zawm screws tuaj yeem deform tooj liab Cheebtsam los yog strip threads. Siv torque wrenches teem rau 8–12 hauv-lbs (0.9–1.36 N·m) rau lub teeb-rau- nruab nrab loads.
4.3 Kev sib txuas hauv cov dej ntub dej
Siv cov roj dielectric los yog silicone caulk rau cov ntsia hlau taub hau thiab cov xov hauv qhov chaw ntub dej (piv txwv li, kav dej, marine) los tiv thaiv cov dej noo{2}} txhim kho corrosion.
4.4 Match Screw Size rau Copper Thickness
- Siv # 6-32 lossis # 8-32 screws rau nyias cov ntawv tooj liab (tsawg dua lossis sib npaug li 1 hli).
