Yuav lub log featened thiab txo elasticity ntawm kev kho mob - qib rank reeters yuav kho?

Kho kom tau thiab cov lus pom zoo kho rau cov log thiab txo qis elasticity rau kev kho mob {}} qib pu casters
Flattened lub log treads thiab txo cov elasticity rau kev kho mob {}}}}}}}}}}}}}}} txoj kab kev tsis pom zoo. Kho rau cov teeb meem no nyob ntawm qhov mob hnyav ntawm kev puas tsuaj. Feem ntau, ua kom tiav rov qab rau thawj tus mob yog qhov nyuaj, yog li kev tiv thaiv thiab hloov yuav tsum tau ua ntej. Cov ncauj lus kom ntxaws yog raws li hauv qab no:

 

I. Kho kev txhim kho tau: Kev kho ib ntus tuaj yeem sim ua kev puas tsuaj me, tab sis kev kho kom yooj yim tsis muaj kev puas tsuaj lossis mob hnyav.

 

1. Cov flatenening me me (lub log tread deformation<5%, no cracks, no surface peeling): Temporary repair is possible, but no permanent cure is possible.
Yog tias cov flattening yog me me (piv txwv li, lub log lub cheeb tsam tsuas yog siv cov teeb meem me me, tab sis tus thawj elasticity, tab sis tus thawj elasticity thiab cov duab yuav tsis rov qab los:

 

Kev ua tshav kub (cov txheej txheem nrog kev ceev faj): Teeb rau ib qho chaw kub, 50-60 degree, tsis txhob tshaj li pU softening taw tes ntawm 80 degree) 10-15cm los ntawm lub log. Ua kom sov thaum maj mam nias lub log saum toj nrog lub tiaj tiaj, khoom siv tawv (xws li qhov tsis muaj zog uas siv cov khoom siv thermoplastic ntawm PU. Tom qab cua sov, cia lub log kom txias rau chav sov (kwv yees li 30 feeb). Hom qauv no tsuas yog kho cov khoom muaj me me thiab tsis tuaj yeem hloov kho kev tsis huv uas yog los ntawm kev laus ntawm kev sib tw hauv txoj sia. Kev tswj kom kub nruj kuj tseem yuav tsum tau los tiv thaiv melting lossis discoloration ntawm lub log nto.

 

Kev tu thiab kho lub log: so lub log nto nrog cov tshuaj kho mob nruab nrab (xws li tshem tawm cov tshuaj tua kab mob tsis zoo (qee cov tshuaj tua kab mob ua kom nrawm dua tuaj yeem ua kom nrawm dua ntawm pU). Tom qab ntawd, maj mam thov siv roj silicone kev kho mob (lossis ua tus pU kho tus neeg sawv cev) rau lub log nto. Qhov no tuaj yeem txhim kho hauv qab smoothness thiab undeviate rolling resistance tshwm sim los ntawm tawv, tab sis nws yuav tsis kho cov poob ntawm elasticity.

 

2. Nruab nrab mus rau kev coj hnyav (lub log sab saum npoo ntau dua lossis sib npaug nrog cov kab nrib pleb thiab kev sib tsoo ntawm kev ua kom tiav): tsis muaj chaw tsis muaj chaw ntxiv thiab yuav tsum hloov.

 

When the PU wheel exhibits the following conditions, the material has been irreversibly damaged, making repair pointless and posing a safety hazard. Hloov yuav tsum tam sim ntawd:

 

Lub log hnyav hnyav: lub log log tau raug txo los ntawm ntau dua 5% (piv txwv li, 100 hli lub taub plawv tau raug txo qis dua 95 hli). Qhov no tuaj yeem yooj yim ua rau lub log defection (lub log tilts thiab ua rau tsis sib xws rau hauv av) thaum lub sij hawm hloov pauv, cuam tshuam rau kev ruaj khov ntawm Txoj kev lis ntshav thiab ntaus ntawv thauj.

 

Tseem ceeb txo elasticity: tsis muaj lub ncoo thaum thawb, thiab lub suab nrov nce siab heev (ntau dua 50 decibels) thaum nyob hauv kev sib cuag nrog hauv av. Txawm tias me me ua pob (xws li cov neeg mob chav tsev neeg mob uas muaj peev xwm hloov tau cov neeg mob lossis cov khoom siv ua rau khoom siv.

 

Accompanied wheel surface damage: Cracks (depth >1 hli) lossis sab nraud picking (ua rau cov khoom sab hauv) tshwm rau ntawm lub log nto. Cov no tsis yog tsuas muaj teeb meem tsis muaj tseeb tab sis kuj tuaj yeem ua rau cov tshuaj tua kab mob thiab hmoov av tuaj yeem ua kom muaj kev pheej hmoo), ua rau muaj kev pheej hmoo ntawm tus ntoo khaub lig-}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}} tus kab mob.

 

Ii. Tus thawj coj ua rau unrepairability: txiav txim los ntawm cov kev laus ntawm cov khoom pu
Elasticity thiab cov qauv kev mob ruaj khov ntawm kev kho mob {}}}}}}}} -}} Linked cov qauv ntawm lub pu molecular chains. Dhau lawm ntev -}}} siv cov lus hauv qab no tuaj yeem ua rau muaj kev puas tsuaj rau cov saw hlau no, ua kom kho tsis tau:

 

Yas deformation los ntawm Long - term load cov kabmob: txawm tias cov khoom siv saib xyuas me me thiab ua rau lub log chaw kom hloov los ntawm cov duab puag ncig mus rau cov duab tiaj tus. Qhov kev deformation no yog mus tas li thiab tsis tuaj yeem thim rov qab los ntawm sab nraud txhais tau tias.

 

Kev Txiaj Ntsig Txog Kev Nyab Xeeb: Thaum 75% Kev haus dej cawv tuaj yeem ua rau lub cev qhuav dej (piv txwv li cov tshuaj tua hluav taws thiab ntev}} Breakage), ua rau Elastomer maj mam ua nruj, irreversibely tsis muaj zog nws elasticity.

 

Kev sib txhuam thiab ib puag ncig kev laus: ntev -} lub sij hawm kev sib txhuam ntawm lub log thiab hauv pem teb tuaj yeem hnav tau cov khoom elastic saum npoo. Tsis tas li ntawd, qhov kub tas mus li thiab muaj cov av noo ntawm tsev kho mob Watally ua kom muaj kev kub ntxhov thiab kev laus ntawm PU, ntxiv txo nws txoj kev elasticity. Cov kev puas tsuaj no yuav tsis tuaj yeem raug kho.

 

III. Cov Lus Taw Qhia Tseem Ceeb: Ua Ntej Hnav Kev Tiv Thaiv, Zam Kev Tiv Thaiv Tshem Tawm
Cov tswv yim tseem ceeb rau kev kho mob - qib taub PU CASters yog "kev tiv thaiv ua ntej, zam kev kho." Kev siv thiab txij nkawm txuas ntxiv lub neej thiab txo cov hnav:
Tswj cov thauj khoom thiab tsis txhob ua haujlwm ntau dua: nruj heev ua haujlwm nyob rau hauv lub tawb yuav tsum muaj kev ntsuas (piv txwv li 100 sid) Qhov no tiv thaiv cov flatchening ua ntej ntawm lub log tread vim ntau dua kev sib txuas.

 

Proper disinfection to minimize damage: Prefer 75% medical alcohol for disinfection (which minimizes damage to the PU). Avoid using high-concentration chlorine disinfectants (e.g., >1000mg / l) lossis undiluted iodine tincture. Tom qab tshuaj tua kab mob, kom sai so qhuav nrog tsis huv

 

Kev tshuaj xyuas ib txwm thiab hloov lub log ua haujlwm txhua lub lim tiam (ntsuas lub log log nrog lub caliper thiab tshuaj xyuas rau cov kab nrib pleb). Ntsuam xyuas cov elasticity txhua ob hlis (xav tias rau lub ncoo thiab mloog lub suab nrov thaum thawb). Cov hnav me me tuaj yeem kho ib ntus. Hloov tam sim ntawd yog tias muaj mob hnav mus txog ntau ntau ntau qib kom tsis txhob muaj teeb meem kev nyab xeeb los ntawm kev siv ntau dhau.

 

Hauv cov ntsiab lus, cov flaturesening thiab txo cov kev kho mob -% kho dua rau cov neeg me me, thaum mob hnyav lossis hnyav yuav tsum hloov chaw. Los ntawm cov kev xav txog kev tiv thaiv kev nyab xeeb (xws li cov cuab yeej ruaj khov thiab kev kawm tu (xws li kev nqus khoom (cia siab rau kev kho tsis pom zoo. Kev tswj hwm tus qauv ua kom txuas ntxiv kom txuas ntxiv rau lub neej thiab kom hloov cov khoom siv hnav kom zoo dua.
