Casters yog ib qho tseem ceeb ntawm ntau yam khoom, tshwj xeeb tshaj yog cov uas xav tau kev txav mus los. Nov yog qee cov ntaub ntawv siv los ua cov casters:
Ib, Metal
Hlau
Hlau yog cov khoom siv ntau heev rau casters. Nws yog lub npe hu rau nws lub zog thiab durability. Steel casters tuaj yeem nqa cov khoom hnyav, ua rau lawv tsim nyog rau kev siv hauv kev lag luam xws li hauv cov chaw tsim khoom uas yuav tsum tau txav mus los ntawm cov tshuab hnyav. Piv txwv li, hauv cov chaw tsim khoom, cov tsheb thauj khoom siv thauj khoom loj thiab hnyav hlau feem ntau muaj steel casters.
Hlau kuj tuaj yeem coated nrog lwm yam khoom los tiv thaiv xeb. Qhov no yog qhov tseem ceeb vim tias cov casters feem ntau raug rau ntau yam ib puag ncig.
Aluminium
Aluminium casters yog sib dua hauv qhov hnyav piv rau cov hlau. Qhov no ua rau lawv xaiv zoo rau cov ntawv thov uas qhov hnyav yog qhov kev txhawj xeeb, xws li hauv qee cov rooj tog zaum uas yuav tsum tau txav mus los tsis tu ncua tab sis tsis txhob nqa hnyav hnyav. Piv txwv li, lub rooj zaum hauv chav ua haujlwm hnyav tuaj yeem siv aluminium casters kom yooj yim txav thaum tseem tuav tau qee theem ntawm lub zog.
2, yas
Polyurethane
Polyurethane yog cov khoom siv yas nrov rau casters. Nws muaj kev poob siab zoo, uas muaj txiaj ntsig zoo hauv cov ntawv thov uas lub caster yuav ntsib cov pob lossis qhov tsis sib xws. Piv txwv li, nyob rau hauv ib lub tsev kho mob, lub txaj nrog polyurethane casters tuaj yeem txav tau yooj yim dhau ntawm qhov tsis sib xws me me hauv pem teb yam tsis muaj kev vibration ntau dhau.
Nws kuj tseem muaj suab nrov qis thaum siv, uas yog qhov zoo dua hauv qhov chaw ntsiag to xws li cov tsev qiv ntawv lossis chaw ua haujlwm.
Nylon
Nylon casters paub txog lawv cov kev puas tsuaj. Lawv tuaj yeem tiv taus hnav thiab tsim kua muag zoo, ua rau lawv haum rau kev siv sijhawm ntev. Hauv qee lub tawb nqa khoom, nylon casters tau siv raws li lawv tuaj yeem tiv taus qhov kev txav mus tas li thiab rub tawm tsam ntau qhov chaw hauv lub tsev muag khoom ib puag ncig.
3, Roj hmab
Khoom Roj Hmab
Cov khoom siv roj hmab casters muab traction zoo heev. Qhov no yog qhov tseem ceeb nyob rau hauv cov xwm txheej uas lub caster yuav tsum tuav hauv pem teb kom zoo, xws li nyob rau ntawm qhov chaw nplua. Piv txwv li, nyob rau hauv ib lub rhiav ntub dej los yog ib lub chaw nres tsheb, cov roj hmab casters ntawm cov cuab yeej tuaj yeem tiv thaiv lub laub los ntawm kev swb thiab zawv zawg.
Pneumatic Roj Hmab (Huab cua puv)
Pneumatic roj hmab casters tau ntim nrog cua. Lawv yog cov zoo rau muab kev caij tsheb du vim lawv tuaj yeem nqus tau cov shocks txawm zoo dua li polyurethane. Lawv feem ntau siv rau hauv cov ntawv thov uas yuav tsum tau ua kom yooj yim thiab du, xws li hauv qee cov rooj tog zaum siab lossis hauv cov tsheb thauj khoom siv hauv tsev cia puav pheej los thauj cov duab zoo nkauj.
