Feem ntau cov neeg siv khoom nug peb cov polyurethane casters tso rau lub sijhawm ntev, kev laus yuav tshwm sim, yooj yim tawg thiab lwm yam tshwm sim, qhov tseeb, qhov no tsis yog teeb meem caster, uas yog ib qho tshwm sim.
Ua ntej, polyurethane caster aging yog vim li cas
Polyurethane caster aging ua rau muaj ntau yam. Feem ntau hais lus, cov laj thawj tseem ceeb ntawm polyurethane caster aging muaj xws li oxidation, ultraviolet hluav taws xob, av noo, kub, tsis kub, tshuaj solvents thiab lwm yam ib puag ncig, nrog rau cov polymer molecular saw ntawm nws tus kheej cov qauv thiab tshuaj stability thiab lwm yam.
Thib ob, polyurethane caster aging cuam tshuam
Polyurethane caster kev laus, nws lub cev thiab tshuaj lom neeg lub zog yuav hloov, manifested li tsaus xim, nto tawg, hardness poob, elasticity txo. Nrog rau qhov hnyav ntawm qib ntawm kev laus, kev ua haujlwm ntawm polyurethane casters yuav maj mam poob haujlwm, nws thiaj li ua rau cov khoom tsis ua haujlwm. Hauv cov ntawv thov, xws li cov ntaub ntawv sib khi hauv tsev, cov khoom siv tawv tawv, cov rooj zaum hauv tsheb thiab lwm qhov chaw, kev laus polyurethane casters tuaj yeem ua rau muaj kev phom sij.
Thib peb, seb polyurethane aging yuav ua rau cov khoom muag muag
Tom qab polyurethane caster aging, lub hardness thiab elasticity ntawm cov khoom yuav txo, uas yuav ua rau softening ntawm cov khoom, tab sis qhov no tsis yog tib txoj kev ntawm manifestation ntawm kev laus. Piv txwv li, qhov poob ntawm compression zog ntawm polyurethane casters yuav ua rau deformation ntawm cov khoom nyob rau hauv quab yuam. Tau kawg, qhov ntsuas kev ua tau zoo ntawm lub cev xws li hardness thiab elasticity ntawm polyurethane casters hloov ua ntej thiab tom qab kev laus, uas yog ib qho tseem ceeb tshaj plaws qhia txog qib ntawm cov khoom laus.
