Dab tsi ib puag ncig cov txheej txheem yuav tsum zam thaum tswj hwm polyurethane casters?

Thaum tswj hwm polyurethane casters, nws yog ib qho tseem ceeb kom tsis txhob muaj plaub qhov chaw ib puag ncig uas tuaj yeem nrawm cov qauv, lossis cuam tshuam rau cov qauv. Cov xwm txheej no yog raws li hauv qab no:

1. Kev ntsuas kub heev: Kev tiv thaiv cov cuab yeej ntawm lub cev
High Temperature Environments (>80 degree)
Cov kev ntsuas qhov kub thiab txias rau kev txwv rau cov khoom siv polyurethane yog kwv yees li 80 degree. Ntev ntev li cas kub (xws li nyob ib ncig ntawm qhov chaw nyob sab nraud thaum lub caij ntuj sov Nws tseem tuaj yeem ua rau cov khoom siv tsis taus thiab tawm ib qho ntxhiab tsw. Qhov no tsis tsuas yog txo cov thauj khoom - bearing muaj peev xwm tab sis tuaj yeem cuam tshuam kev mus vim lub log tsuj rau hauv av. Qhov kub hnyav tshaj 120℃kuj tuaj yeem ua rau muaj kev tiv thaiv ib feem ntawm lub log, rendeling nws tsis muaj.

Tsawg qhov chaw ib puag ncig (<-20°C)
Ntawm qhov kub hauv qab no - 20 degree, polyurethane maj mam plam nws cov tawv ncauj, ua txhav thiab nkig. Dov Nquag thawb lossis hnyav thauj khoom ntawm qhov kub no tuaj yeem ua rau lub log tsuj los yog txawm tawg los ntawm cov pob. Qhov no ua rau lub log tshwj xeeb tsis tsim nyog rau cov khoom txias lossis kev siv sab nraum zoov nyob rau sab qaum teb Winters, qhov twg lub log raug rau cov kub tsawg.

2. Cov khoom siv tshuaj xeb ib puag ncig: zam cov khoom tsis txheeb
Zam kev sib cuag ncaj qha nrog cov kuab tshuaj muaj zog, muaj zog acids, thiab muaj zog muaj zog. Cov no suav nrog:

Cov kuab tshuaj muaj zog xws li roj av, acetone, cov roj tsawb ua kom yaj, ua kom pom kev zoo nkauj, ua kom muaj kev puas tsuaj rau lub sijhawm luv luv.

Muaj zog acids / bases xws li muaj hydrochloric acid, thiab sodium dej ntshiab (ua kom lub log Lawv kuj tseem tuaj yeem correde lub tais diav (xws li tus qauv hlau nkhaus), ntxiv kev puas tsuaj tag nrho. Txawm tias muaj cov tshuaj ntxuav kua zog tsis muaj zog thiab cov tshuaj txhuam alkaline siv hauv cov zaub mov / cov ntaub ntawv thov tshuaj, tsis txhob so kom qhuav tom qab tu.

3. High {{{{{1} abr abr and and thiab cov chaw nres nkoj impurity: tiv thaiv lub cev puas tsuaj rau lub log nto

Ntxhib thiab nyuaj zaum, xws li cov pob zeb tsis sib xws, tuaj yeem tsim lub log nto, thiab cov kev coj ua, nrawm dua, thiab tawg. Lawv txawm yuav ua kom muaj cov impurities belurities pierce (tshwj xeeb yog tsis muaj- ci polyurethane casters).

Nquag khiav hla kev cov nyom, xws li tsa cov hlau sib tw, ua kom muaj kev ntxhov siab ntau yam ntawm lub log, thiab tseem xoob qhov kev sib txuas ntawm cov kabmob thiab lub log, cuam tshuam tag nrho kev ruaj ntseg.

4. Av noo thiab muaj kuab paug nyob ib puag ncig: zam kev txhim kho kev txhim kho thiab kev ua haujlwm tsis zoo. Ntev -} kev vam meej av noo, xws li nyob rau hauv chav ntxhua khaub ncaws cov khoom noj los yog qhib cov dej qab zib ua kom pom cov khoom noj kom zoo nkauj Vaum kuj tseem ua kom nrawm nrawm ntawm kev laus ntawm polyurethane log (tshwj xeeb yog cov uas tsis yog dej paug), txo lawv lub neej pabcuam.

Cov hmoov av siab / roj ntxiv, xws li cov hmoov nplej hauv cov hmoov thiab cov ntaub ntawv ua haujlwm, muaj peev xwm txhaws cov kabmob, ua rau lubrication tsis ua haujlwm thiab stalling. Cov roj nplaum roj rau lub log nto rau ncua sijhawm, nkag mus rau lub polyurethane thiab cuam tshuam rau nws elasticity. Cov hmoov av tsis tau tuaj yeem nce rolling tsis kam thiab ua kom hnav.
