Feem ntau cov pins yog carbon steel los yog stainless steel—tsis yog cov khoom kim heev, tsuas yog cov uas ua haujlwm tau zoo xwb. Carbon steel yog tus neeg uas pheej yig thiab ruaj khov: muaj zog txaus rau feem ntau txoj haujlwm, tab sis yog tias nws nyob hauv qhov chaw ntub dej ntev dhau? Nws yuav xeb (ntseeg kuv, kuv tau pom nws ntawm cov hinges qub). Stainless steel? Nws yog tus yeej sab nraum zoov—nag, av nkos, txawm tias cov tshuaj lom neeg nchuav tsis ua rau nws puas tsuaj. Xav kom lawv kav ntev dua? Ntxiv zinc plating (tsis txhob xeb me ntsis ntawm carbon steel) lossis black oxide (tsis yooj yim khawb thiab zoo nkauj dua, uas zoo rau cov khoom siv hauv tsev). Txawm li cas los xij, lawv tuav tau hauv chav nres tsheb, chaw tsim khoom, lossis txawm tias nyob hauv thaj teb.
Cov pins tsis zoo ib yam - koj yuav tsis siv lub wrench rau lub screwdriver, puas yog? Qee qhov xauv nruj, qee qhov kho tau yooj yim, qee qhov tsuas yog ua kom cov khoom ncaj. Nov yog cov uas koj yuav ntsib, nrog rau qhov tseeb ntawm cov carbon thiab stainless hlau:
Cov Hlau Carbon Pin:Qhov no yog "cov khoom siv ua haujlwm" uas koj yuav pom txhua qhov chaw - feem ntau yog ua los ntawm cov hlau carbon qis lossis nruab nrab (1045 yog qhov feem ntau, yog tias koj xav paub). Qhov yeej loj? Nws muaj zog heev - Kuv tau siv cov no rau ntawm cov pulley shafts uas tuav cov siv hnyav, thiab lawv yeej tsis khoov. Qhov ntes? Qhov ntub dej yog nws tus yeeb ncuab. Kuv ib zaug muaj tus pin hlau carbon ntawm lub laub sab nraum zoov xeb khov kho hauv ib hlis - yog li ntawd muab zinc rau nws lossis siv nws sab hauv, zoo li ntawm cov hinges tshuab.
Tus Pin Hlau Tsis Muaj Hlau:304 stainless yog qhov zoo tshaj plaws rau ntawm no, thiab muaj laj thawj zoo. Los nag, ntsev ntawm txoj kev, txawm tias cov tshuaj me me? Nws tsis quav ntsej. Koj tsis tas yuav ntxiv plating, thiab nws muaj zog txaus rau feem ntau txoj haujlwm - ntxiv rau, nws tsis yog magnetic. Qhov ntawd yog tus cawm txoj sia rau cov thawv hluav taws xob lossis cov khoom siv kho mob - xyoo tas los, tus neeg siv khoom siv cov no los teeb tsa cov laug cam, thiab tsis muaj kev cuam tshuam nrog cov khoom siv hluav taws xob ntxiv lawm. Tsis muaj "vim li cas lub tshuab thiaj li ua haujlwm tsis raug?" vim yog lub pin magnetic.
Xaiv tus pin zoo tsis yog ib qho yooj yim ua, tab sis nws tseem ceeb heev—siv tus tsis yog, thiab koj yuav kho nws dua lub lim tiam tom ntej. Nov yog qhov uas txhua hom ua haujlwm zoo tshaj plaws:

Cov hlau carbon tuab hla qhov hnyav kom zoo—tsis txhob txhawj txog qhov boom plam lawm.
Ntawm Yuhuang, peb tsis ua cov lus tsis meej pem - tsuas yog qhia rau peb paub tias koj xav tau dab tsi, thiab peb yuav ua tiav. Kuv tau pab cov neeg siv khoom kho cov pins rau txhua yam los ntawm cov tshuab me me mus rau cov khoom siv loj, thiab nws ib txwm yog tib yam 5 yam yooj yim uas peb xav tau:
1. Khoom siv:1045 carbon steel yog tias koj xav tau lub zog (zoo li rau cov tshuab hnyav), 304 stainless rau kev tiv thaiv xeb (sab nraum zoov lossis cov chaw ntub dej), lossis 316 stainless yog tias koj tab tom cuam tshuam nrog cov tshuaj lom neeg tawv (zoo li hauv cov chaw tsim khoom).
2. Hom:Cov hlau carbon rau cov khoom hnyav, stainless hlau rau kev ruaj khov, lossis cotter pin rau kev xauv - tsuas yog xaiv qhov uas haum rau koj txoj haujlwm.
3. Qhov Loj:Qhia rau peb paub qhov loj me—yog tias nws khoob, nws yuav tsum haum rau saum tus ncej, nws yuav tsum phim lub qhov hauv koj qhov—tsis txhob kwv yees qhov no), ntev (nyob ntawm seb cov khoom koj txuas tuab npaum li cas), thiab tej qhov tapers lossis grooves (kom nws tsis txhob plam).
4. Kev Kho Mob Nto:Zinc plating rau kev tiv thaiv xeb sab hauv tsev (zoo rau cov hlau carbon), dub oxide rau kev tiv thaiv khawb (zoo nkauj dua), lossis kub-dip galvanizing rau kev siv sab nraum zoov (stainless lossis carbon - kav ntev xyoo).
5. Cov Kev Xav Tau Tshwj Xeeb:Muaj dab tsi ntxiv? Tsis muaj hlau nplaum rau cov khoom siv hluav taws xob? Tsis kub rau cov khoom siv cav (peb muaj ib tus neeg siv khoom xav tau qhov no rau cov tshuab tso pa tawm - ua haujlwm zoo heev)? Txawm tias cov duab kos tshwj xeeb (los cim koj lub npe lossis tus lej ntawm qhov khoom - yooj yim rau cov khoom muag)?
6. Qhia cov no thiab peb yuav teb rau koj hauv 24 teev kom pom tias nws ua tau. Kuv txawm muab qee cov lus qhia. Piv txwv li, yav dhau los, tus neeg siv khoom xav tau cov hlau carbon rau kev siv sab nraum zoov. Kuv tau hais kom siv cov galvanizing kub-dip kom tsis txhob muaj teeb meem xeb. Peb xyuas kom meej tias lub koob kawg haum, zoo li lawv tsuas yog rau koj qhov teeb tsa - tsis yog "ze txaus" ntawm no.
Q: Kuv yuav xaiv li cas ntawm cov hlau carbon thiab cov hlau stainless?
A: Yooj yim—yog tias nws nyob sab hauv (cov pob qhov rooj tshuab, cov tsheb thauj khoom sab hauv tsev) thiab koj xav tau lub zog ntawm cov peev nyiaj tsawg, mus rau cov hlau carbon. Yog tias nws nyob sab nraud, ntub dej, lossis ze ntawm cov khoom siv hluav taws xob / khoom siv kho mob (cov khoom siv tsheb, cov txee server), cov hlau tsis xeb yog txoj hauv kev. Kuv tau muaj cov neeg siv khoom xaiv cov pa roj carbon rau kev siv sab hauv tsev thiab txuag tau 20%—ua haujlwm txhua lub sijhawm.
Q: Yuav ua li cas yog tias tus pin pheej plam tawm ntawm lub rooj sib dhos?
A: Hloov rau tus pin cotter—khoov cov kawg, thiab nws yuav tsis txav. Los yog ntxiv lub nplhaib tuav. Yog tias muaj kev co ntau (zoo li hauv lub cev muaj zog), siv tus pin grooved—nws tuav lub qhov zoo dua. Kuv ib zaug tau muaj tus neeg siv khoom siv cov kua nplaum xauv xov rau ntawm tus pin hauv lub tshuab tshee—tsis plam ntxiv lawm.
Q: Kuv puas yuav tsum hloov cov pins thaum kuv hloov bolts lossis txiv ntoo?
A: Yog lawm, yeej muaj tseeb. Cov pins yuav lwj tag—cov hlau carbon xeb, cov hlau stainless kuj khawb—thiab qhov ntawd ua rau lawv tsis raug. Xyoo tas los, ib tug txiv neej siv cov pins hlau carbon qub rau ntawm nws lub tsheb laij teb lub tshuab ncua, thiab lawv tawg ib lub lim tiam tom qab. Tsis tsim nyog pheej hmoo—hloov lawv nrog cov bolts.
Q: Cov hlau stainless hlau puas tuaj yeem tiv taus qhov kub siab?
A: 304 stainless ua haujlwm txog li 800 ° F - zoo rau feem ntau txoj haujlwm. Yog tias koj xav tau kub dua (xws li lub cav tso pa tawm, uas mus txog 1,800 ° F), siv 310 stainless - nws tuav txog li 2,000 ° F. Tsuas yog xyuas nrog peb ua ntej - peb yuav xyuas kom meej tias nws yog rau koj qhov kub.
Q: Kuv puas yuav tsum tau hloov cov hlau carbon uas xeb lawm?
A: Yog tias nws tsuas yog me ntsis xeb xwb (tsis muaj qhov khoov lossis qhov tawg), ntxuav nws nrog txhuam hlau thiab siv nws rau cov khoom tsis tseem ceeb - xws li lub pob qhov rooj rooj tog. Tab sis yog tias nws xeb heev, khoov, lossis nyob rau hauv ib yam dab tsi muaj kev nyab xeeb-qhov tseem ceeb (nres, cov khoom siv hauv kev tsim kho)? Hloov nws. Kuv tau pom cov ntsia hlau xeb ntawm scaffolding - yeej tsis tsim nyog txiav cov ces kaum.
