Dhau li ntawm cov roj hmab thiab cov log nylon, yog dab tsi lwm hom casters yog tsim nyog rau kev ntub dej?

Hom ntawm cov casters lwm yam dua li roj hmab thiab cov log nylon tsim nyog rau cov chaw ntub dej

Dhau li ntawm cov roj hmab thiab cov log nylon, cov cuab yeej tsim nyog rau cov chaw ntub dej yuav tsum tau ua kom cov chaw ntub dej Cov khoom siv hauv qab no, los ntawm lawv cov khoom siv lossis tsim kho kom haum rau ib puag ncig ntub dej (xws li cov chaw ntub dej, thiab cov dej nag sab nraum zoov ib puag ncig). Lawv cov yam ntxwv tshwj xeeb thiab cov xwm txheej haum muaj raws li hauv qab no:

1. POLYURETHANE (PU) COTERS: Kev xaiv sib npaug "uas cuam tshuam los tiv thaiv - horrosion tsis kam

Txawm hais tias cov log av polyurethane feem ntau teev nyob nrog cov roj hmab thiab cov log nylon nyob rau hauv cov chaw ntub dej thiab muaj tshwj xeeb rau cov av noo - cov xwm txheej corrosion "scenarios:

Tub ntxhais nta:

Zoo heev los anti -}} Lub log elicting ntawm cov roj hmab thiab lub log me me) rau cov lej me me plam.
Dej - tiv taus thiab cov khoom siv ntshiab, thiab tsis muaj zog} Nws yog cov kev siv tshuaj ntau dua li cov roj hmab zoo tib yam.
Nyob ntsiag to thiab qis {{0} he}} Cov khoom siv zoo dua li 0.2-piab yuav tsum muaj li 0.2-
Cov ntawv thov uas tsim nyog: Cov chav ua zaub mov ua kom huv (av noo thiab cov khw ntub dej hauv tsev), thiab cov khw hauv tsev kho mob (noo thiab xav tau kev ua haujlwm ntsiag to). Nws yog tshwj xeeb rau nqa nruab nrab - cov khoom hnyav (100-300kg ib lub log), xws li cov khoom xa tuaj thiab cov laub tu.

2. Stainless Hlau Casters: Qhov kev xaiv ntev rau cov av noo thiab mob hnyav
Stainless hlau log, nrog lawv txhua - cov khoom siv cov khoom siv muaj zog, yog tsim kom haum rau kev lag luam -}}}}.
Cov Nta Tseem Ceeb:
Huab corrosion Kuj: Lub log log thiab bracket feem ntau ua los ntawm kev siv tshuaj tsw qab thiab muaj kuab acidic (xws li cov pa roj ntsha tsis huv thiab cov pa roj av) Nws yuav tsis xeb lossis deform txawm tias tom qab ntev - kev raus raus Immersion.
Siab load - bearing beligness lub cev muaj qhov hnyav}} Thaj chaw vaum.
Kev Tu Kom Yooj Yim thiab Kev Txij Nkawm: Tus du, tsis {0} {{0} pale acous nto tsis kam lees cov nplaum ntawm av (xws li roj thiab zaub mov noo. Cias yaug nrog dej huv, tshem tawm cov kev txhawj xeeb ntawm kev txhawj xeeb ntawm cov storms thiab corrosion. Haum rau kev siv nyob rau hauv electration kev cob qhia (tshwm sim rau acidic thiab noo cov khoom siv nyob rau hauv ntug hiav txwv (raug cov khoom siv tshuaj ntsuab (raug rau cov khoom siv hluav taws xob (raug rau cov khoom lag luam noo noo). Nco tseg: Stainless hlau log yog qhov nyuaj thiab tuaj yeem yooj yim kos cov chaw mos zoo li epoxy plag tsev. Lawv yog cov haum ntau rau cov chaw tawv zoo li cement thiab pob zeb ua.

3. POLYTETRARUOROEENTOROEEN (PTFE) Casthylene (PTFE) casters: "Xaiv" rau cov av noo + siab + siab / tsawg kub
Polytetrafluoroethylene (feem ntau hu ua "Teflon") casters, yog qhov tsim nyog rau cov kev siv vaum thiab kub ib puag ncig, sau cov khoob ntawm cov chaw ua kom haum.
Tub ntxhais nta:
Qhov kub thiab txias thiab dej kub tsis kam: lawv ua haujlwm ruaj khov nyob rau hauv kub ntawm -} 200℃rau 260 degree. Lawv yuav tsis ua nkig lossis mos noo noo noo (xws li cov dej kub thiab noo noo}}}}}} kub txias chaw nres tsheb). Lawv yog tag nrho tsis yog - dej- pa absor absor}} nqus tau kev hloov pauv txawm tias muaj kev sib cuag ntev nrog dej lossis chav.
Corrosion Kuj: Lawv pom kev tshwj xeeb ntawm cov tshuaj ruaj khov, xws li sulfuric acid) thiab cov khoom siv hydrocide (xws li sodium hydroxide tov). Txawm hais tias nyob rau hauv ib puag ncig huab cua, lub log lub log yuav tsis yaj los yog tso cov tshuaj ua kom zoo, ua rau lawv haum rau cov khoom noj thiab tshuaj lag luam.
Tsis muaj kev sib txhuam yooj yim thiab yooj yim heev rau cov roj hmab}}}

Cov xwm txheej haum: Cov chaw ua zaub mov noj ua noj (huab cua sov thiab muaj zog thiab cov av noo thiab av noo thiab ib puag ncig} 1 xuaj moos. Mas siv rau lub teeb - Cov log tsheb qis dua (ib leeg log load tsawg dua lossis sib npaug rau 100kg), xws li lub laub nqa thiab cov khoom siv me me hloov chaw.

4. Nitrile Roj Hmab (NBR) Casters: xaiv tshwj xeeb rau ntub thiab muaj roj av
Roj Hmab Roj Hmab yog ib qho subtype ntawm roj hmab tsim tshwj xeeb rau kev sib xyaw ntub dej thiab roj muaj ib puag ncig. Nws yog ntau roj - Thiab dej {{{{{{tiv taus tshaj cov roj hmab zoo li qub, ua kom haum rau kev lag luam, oily chaw.
Cov Nta Tseem Ceeb:
Roj thiab dej tsis kam: nitrile roj hmab muaj acrylolonitrile pab pawg, ua rau nws tiv taus kev xeb ntawm cov ntxhia thiab zaub roj. Nws yuav tsis o lossis tawg hauv cov plag tsev noo hauv cov tshuab roj av), thiab roj av {{1} {}}-- ntev dua li ntawm cov roj hmab hluav taws xob.
Siab elasticity thiab anti {- zoo ib yam li ntawm cov roj hmab thiab roj av, tiv thaiv kev sib tsoo los ntawm cov roj. Lub log saum toj no tseem hnav-resistant (hnav tus nqi tsawg dua lossis sib npaug rau 0.4g / 1000 txoj kev hloov kho), ua rau nws haum rau kev txav nquag.
Muaj zog kev laus: Ntxiv ntawm cov antioxidants slows kev laus hauv cov roj hmab noo, ua rau lub neej pabcuam txog li 1 - 2 xyoo. Haum rau kev siv hauv machining cov chaw (roj {}} {} {}} Cov plag tsev ntub dej), thiab roj av kho cov plag tsev Haum rau lub teeb - rau-nruab nrab loads (ib lub log load muaj peev xwm 50-200kg).

Ntsiab lus: Xaiv cov casers casers raws cov kev nyuaj ntawm qhov chaw ntub dej.
Rau ib txwm muaj ntub dej (tsis muaj xeb, tsis muaj roj): polyurethane log yog qhov nyiam dua (nrawm nrawm thiab ntev).
Rau cov ntub dej nrog cov hlab ntshav loj / ntsev tshuaj tua kab: stainless hlau log (304/316 khoom) yog qhov tseem ceeb.
Rau ntub dej nrog cov siab / tsawg kub: polytetrafluoroethylene log (huab cua sov heev).
Rau cov ntub dej nrog cov roj: nitrile roj teeb log (roj thiab swb tsis kam). Cov khoom siv no tau tsim los nrog cov khoom siv hom phiaj los npog tshwjxeeb noo noo uas roj hmab thiab nylon log yog qhov yooj yim kom yoog raws. When selecting a caster, a comprehensive judgment should be made based on "humidity level + whether it is accompanied by corrosion/oil pollution/temperature fluctuations + load-bearing requirements". Nyob rau tib lub sijhawm, xyuas kom meej tias cov qag thiab cov bracket tseem ua tau ua los ntawm cov xeb- cov ntaub ntawv pov thawj (xws li tsis ua tiav vim xeb ntawm cov seem sib txuas.
