Roj hmab thiab polyurethane yog cov khoom siv hauv kev lag luam, thiab ob qho tib si yog cov khoom siv tseem ceeb uas siv los ua cov khoom siv log caster. Ob qho tib si muaj lawv tus kheej qhov zoo thiab qhov tsis zoo, thiab ntu tom ntej no tshawb nrhiav qhov sib txawv kom meej, nrog rau cov xwm txheej uas koj yuav tsum xaiv cov khoom siv twg.
Cia peb pib los ntawm kev saib qhov sib txawv ntawm roj hmab thiab polyurethane. Roj hmab yog ib feem puag ncig ua los ntawm cov khoom siv roj hmab uas feem ntau yoog tau thiab tsis plam. Roj hmab feem ntau yog muab faib ua roj hmab ntuj thiab roj hmab hluavtaws, thiab tuaj yeem hloov kho rau qhov nyuaj thiab kev tiv thaiv kev sib txhuam raws li qhov xav tau. Polyurethane feem ntau nyuaj dua thiab tiv thaiv kev sib txhuam ntau dua li cov roj hmab casters. Polyurethane casters feem ntau yog ua los ntawm polyurethane elastomers, uas muaj qhov ceev thiab tawv dua.
Qhov thib ob, cov roj hmab casters thiab polyurethane casters ua haujlwm sib txawv hauv ntau qhov xwm txheej sib txawv. Cov roj hmab casters ua tau zoo hauv kev ywj pheej, tiv thaiv kev plam thiab suab rwb thaiv tsev, thiab pheej yig thiab yooj yim rau kev ua thiab tsim khoom. Yog li ntawd, cov roj hmab casters yog qhov kev xaiv zoo dua hauv cov xwm txheej uas xav tau kev ywj pheej thiab kev poob siab, xws li hauv cov khoom siv kho mob, rooj tog, cov khoom siv hluav taws xob thiab cov khoom siv kis las. Polyurethane casters, ntawm qhov tod tes, ua tau zoo dua hauv kev tawv, kev tiv thaiv kev sib txhuam, thiab lub peev xwm thauj khoom, yog li lawv tsim nyog dua hauv kev lag luam, kev tsim khoom, thiab kev tsim kho qhov twg xav tau kev nqa hnyav.
Ob hom casters kuj txawv ntawm kev tiv thaiv ib puag ncig. Cov roj hmab casters xav tau kev siv cov tshuaj lom neeg hauv cov txheej txheem ntau lawm, xws li cov neeg sawv cev vulcanizing thiab accelerators, uas yuav ua rau ib puag ncig muaj kuab paug. Polyurethane casters, ntawm qhov tod tes, yog cov phooj ywg ib puag ncig ntau dua vim tias lawv yog cov khoom siv rov ua dua tshiab thiab tsim cov khib nyiab tsawg dua thaum lub sijhawm tsim khoom.
Thaum kawg, hais txog tus nqi, cov roj hmab casters pheej yig dua thaum cov polyurethane casters kim dua. Qhov no yog vim tias cov ntaub ntawv polyurethane kim dua thiab nyuaj rau ua, yog li cov polyurethane casters kim dua. Cov ntaub ntawv roj hmab, ntawm qhov tod tes, pheej yig dua thiab cov txheej txheem tsim khoom yooj yim dua, yog li cov roj hmab casters pheej yig dua.
Yog li, thaum xaiv cov roj hmab casters thiab polyurethane casters, koj yuav tsum xaiv li cas?
Qhov tseeb, ob qho tib si muaj lawv tus kheej qhov zoo thiab qhov tsis zoo, thiab qhov kev xaiv tshwj xeeb yuav tsum nyob ntawm qhov xwm txheej. Yog tias koj xav tau elasticity, tiv thaiv kev plam thiab kev poob siab, xws li hauv rooj tog, khoom siv hluav taws xob thiab cov khoom siv kis las, koj yuav tsum xaiv cov roj hmab casters. Yog tias koj xav tau cov casters uas muaj peev xwm hnyav dua thiab tiv taus kev puas tsuaj, xws li hauv kev lag luam, kev tsim khoom thiab kev tsim kho, koj yuav tsum xaiv cov polyurethane casters.
Sib nrug ntawm cov roj hmab casters thiab polyurethane casters, muaj lwm hom casters xws li nylon casters thiab PP casters. Txhua hom caster muaj nws tus kheej qhov zoo thiab qhov tsis zoo thiab yuav tsum tau xaiv raws li qhov xav tau tiag tiag. Tsis tas li ntawd, thaum xaiv cov casters no, koj yuav tsum tau them sai sai rau qhov tuab ntawm lub phaj hlau ntawm lub bracket, cov khoom siv phaj hlau, feem ntau, txiav txim siab lub peev xwm thiab kev nyab xeeb ntawm cov casters, yuav tsum tsis txhob tsis quav ntsej, sim xaiv cov khoom siv hlau manganese ntawm cov caster, qhov zoo thiab kev ntseeg siab ntawm nws yog siab dua li cov hlau ib txwm.
Tau kawg, yuav tsum tau them sai sai rau qhov loj ntawm cov casters nrog rau kev teeb tsa, kom ntseeg tau tias kev teeb tsa du, yog li nws txoj haujlwm ib txwm muaj.
