Rov qab rau thaum ntxov ntawm kev txhim kho thiab siv cov casters - 100 xyoo dhau los lossis ntau dua - muaj ob peb xaiv rau cov khoom siv log. Yog tias koj xav tau lub log nyuaj, koj siv hlau. Yog tias koj xav tau cov log mos, cov roj hmab ntuj yog qhov kev xaiv tseem ceeb. Thiab yog tias koj xav tau ib yam dab tsi hauv nruab nrab, ntoo yog qhov kev xaiv nrov.
Tias tag nrho cov pib hloov nyob rau hauv lub 1930s, thaum muaj tshiab kev tsim kho nyob rau hauv cov ntaub ntawv hluavtaws xws li plastics, ua rau muaj kev tawg ntawm kev xaiv rau cov ntaub ntawv caster log. Hauv particular, ob yam khoom siv hluavtaws zoo li roj hmab pib hloov cov roj hmab ntuj.
Neoprene
- Qhov no yog cov roj hmab hluavtaws ua los ntawm cov polymerization ntawm qee yam tshuaj xws li chloroprene. Nws yog ib qho elastomer, txhais tau hais tias thaum ncab nws muaj lub cim xeeb, thiab yuav rov qab mus rau nws txoj hauj lwm tsis ncab, zoo li roj hmab ua. Tsis zoo li roj hmab, txawm li cas los xij, neoprene tiv taus cov roj, roj, tshuaj hnyav thiab kub siab. Qhov no ua rau nws yog ib qho khoom siv zoo tshaj plaws los siv rau lub log caster.
Polyurethane
- kuj yog hluavtaws roj hmab. Nws feem ntau yog ua los ntawm kev sib txuas cov kev daws teeb meem ntawm ob lossis ntau dua cov tshuaj, nchuav cov khoom sib tov rau hauv pwm, thiab ua cov khoom xav tau. Cov neeg tsim khoom tuaj yeem tswj hwm cov khoom ntawm cov khoom kawg los ntawm kev sib txawv ntawm cov khoom xyaw ntawm cov khoom pib, thiab los ntawm cov txheej txheem tsim khoom sib txawv. Caster log ua los ntawm polyurethane tuaj yeem tsim nrog ntau yam hardness, los ntawm mos mus rau qhov nyuaj heev. Raws li kev tsim qauv, polyurethane casters tuaj yeem tiv taus roj, roj thiab tshuaj lom neeg zoo heev.
Ob qho khoom siv tau los ntev txij li xyoo 1930s, thiab tam sim no muaj ntau yam sib txawv rau cov log tsheb. Qhov tseeb, vim tias lawv cov khoom zoo tshaj plaws, lawv yuav luag tag nrho hloov cov roj hmab ntuj raws li kev xaiv rau cov log tsheb.
Niaj hnub no, nws yog ib qho nyuaj rau qhia qhov txawv ntawm cov khoom siv hluavtaws "rubber" thiab cov roj hmab ntuj nws tus kheej. Thaum peb cov neeg siv khoom xav tau cov casters mos, lawv yuav nug peb cov roj hmab casters. Peb feem ntau nug cov lus nug txog lawv daim ntawv thov, tom qab ntawd pom zoo rau polyurethane lossis neoprene casters.
Hauv qab no peb mam li sib piv neoprene thiab polyurethane, nrog rau lub hom phiaj ntawm kev pab koj txiav txim siab seb yam khoom twg yog qhov zoo tshaj plaws rau koj cov kev xav tau.
Neoprene Caster Wheels
Ib qho ntawm cov yam ntxwv tseem ceeb ntawm neoprene log yog lawv txoj haujlwm du, ntsiag to. Txawm hais tias lawv yuav zoo li mos, cov khoom siv neoprene yog qhov ruaj khov heev. Lawv yog cov zoo heev rau kev tiv thaiv hauv pem teb, thiab feem ntau xaiv los ua casters rau chaw ua haujlwm zaum. Lawv ua haujlwm zoo rau ntau qhov sib txawv hauv pem teb, tab sis yuav tsis kos lossis kos hauv pem teb. Lawv nyob ntsiag to heev thaum lawv dov hla cov chaw ua haujlwm hauv pem teb, tshwj xeeb tshaj yog thaum piv rau cov yas tawv tawv casters siv ntawm qee lub rooj zaum hauv chaw ua haujlwm.
Lwm qhov kev ntshaw ntawm neoprene yog nws cov tshuaj tiv thaiv. Qhov no ua rau neoprene casters zoo tagnrho rau siv nyob rau hauv cov xwm txheej uas muaj roj los yog roj. Neoprene tsis cuam tshuam los ntawm dej, ncu lossis tshuaj hnyav.
Rau kev ntxiv dag zog, neoprene feem ntau txuas rau cov khoom siv tseem ceeb. Lub txheej txheej ntawm neoprene ua rau lub log tread, thaum lub hauv paus muab cov qauv.
Neoprene cov khoom ua rau nws muaj kev xaiv nrov hauv cov ntawv thov zoo li no:
Cov khoom siv kho mob thiab chaw kuaj mob, xws li cov tsheb thauj neeg mob thiab IV sawv ntsug
Carts rau mobile computers
Cov rooj tog zaum hauv chaw ua haujlwm thiab cov rooj zaum, tshwj xeeb tshaj yog cov rooj zaum ergonomic
Hnyav tshuaj ntxuav qhov chaw, hauv tsev kho mob lossis chaw ua zaub mov
Nco ntsoov tias feem ntau ntawm kev siv tau hais los saum toj no yog rau chaw ua haujlwm, kho mob lossis chaw teeb pom kev lag luam. Rau cov khoom siv hnyav hnyav, polyurethane casters yog nrov. Peb yuav tham txog cov tom ntej no.
