Thaum xaiv cov casters, "kev tiv thaiv kev hnav" feem ntau suav hais tias yog ib qho cim qhia, tab sis qhov tseeb txiav txim siab lub neej ntawm lub log feem ntau yog "khoom siv + kev ua haujlwm". Txawm tias rau tib hom log thoob ntiaj teb, nylon (PA), polyurethane (PU), thiab roj hmab qhia txog kev tiv thaiv kev hnav sib txawv, suab nrov, kev sib raug zoo hauv av, lub peev xwm thauj khoom, thiab kev hloov pauv ib puag ncig. Raws li cov ntawv qub, tsab xov xwm no ntxiv nrog cov yam tseem ceeb cuam tshuam, cov ntsiab lus sib piv, thiab cov lus qhia txog qhov xwm txheej ib txwm muaj los pab koj xaiv sai hauv cov xwm txheej xws li cov chaw tsim khoom, tsev rau khoom, tsev kho mob, thiab tshav dav hlau.
1. Dab tsi txiav txim siab qhov hnav tsis kam? Ua ntej, cia peb piav qhia plaub yam tseem ceeb no:
1). Cov khoom siv hauv av thiab qhov ntxhib: Cov cement/asphalt ntxhib yuav ua rau hnav sai dua; cov plag tsev du xws li epoxy/PVC muaj qhov hnav tsawg dua, tab sis lawv txhawj xeeb ntau dua txog "cov cim dub/khawb".
2). Lub peev xwm thauj khoom thiab kev siv: Lub nra hnyav tsis txav (chaw nres tsheb) ≠ Lub nra hnyav hloov pauv (thawb). Tig ntau zaus, tig rau hauv qhov chaw, thiab hla qhov chaw tsis sib luag yuav ua rau lub log puas thiab puas tsuaj ntau ntxiv.
3). Kev ceev thiab kub: Thaum ua haujlwm ntawm kev kub ceev, kev tuav ntawm qhov deb ntev, lossis hauv qhov kub thiab txias siab, qhov kub uas tsim los ntawm lub log nto tuaj yeem cuam tshuam rau qhov nyuaj ntawm cov khoom siv thiab kev ruaj khov hnav.
4). Tshuaj lom neeg thiab ib puag ncig huv si: Cov roj av, cov tshuaj ntxuav acid thiab alkali tsis muaj zog, thiab kev yaug ntub dej tuaj yeem cuam tshuam rau kev laus ntawm cov khoom siv thiab lub neej ntawm cov bearings / kev txhawb nqa, ua rau "qhov ntau koj siv, qhov kim dua lub log."
2. Kev Sib Piv ntawm Kev Tiv Thaiv Kev Hnav thiab Cov Yam Ntxwv ntawm Peb Cov Khoom Siv
Cov kev sib piv hauv qab no yog raws li cov ntaub ntawv siv hauv kev lag luam / kev lag luam. Tej zaum yuav muaj kev hloov pauv vim muaj ntau hom qauv, qhov nyuaj, cov txheej txheem (txhaj tshuaj molding / casting / vulcanization), qhov dav ntawm lub log, thiab cov qauv ntawm cov kabmob. Nws raug pom zoo kom saib cov qauv kuaj thiab cov xwm txheej ua haujlwm tiag tiag.
