Thaum xaiv cov khoom ntawm cov khib nyiab casters, PU (polyurethane) thiab roj hmab txhua tus muaj lawv tus kheej qhov zoo thiab qhov tsis zoo, uas yuav tsum tau txiav txim siab raws li kev siv scenario thiab cov cai.
1. Cov yam ntxwv ntawm PU casters
1) Qhov zoo:
A. Muaj zog hnav tsis kam: cov khoom siv PU muaj qhov tawv tawv thiab tsim nyog rau kev siv ntau zaus lossis cov xwm txheej hnyav (xws li warehouses thiab workshops). Nws lifespan feem ntau yog ntev dua li roj hmab.
B. Muaj peev xwm thauj khoom tau zoo: tsim nyog rau kev nqa cov khoom hnyav (xws li cov txee rau khoom).
C. Tshuaj/Oil Resistance: Tsis yooj yim corroded los ntawm cov roj los yog cov kuab tshuaj, haum rau ib puag ncig xws li kuaj thiab factories.
D. Cov nyhuv txo suab nrov zoo dua: Txawm hais tias tsis nyob ntsiag to li roj hmab, nws yog ntsiag to dua li cov ntaub ntawv nyuaj xws li nylon.
2) Disadvantages:
A. Cov elasticity tsis zoo: Cov nyhuv poob siab tuaj yeem ua rau tsis txaus ntawm cov khoom ntxhib xws li cov cement flooring.
B. Tsawg kub hardening: Flexibility yuav txo tau nyob rau hauv qhov chaw txias.
2. Cov yam ntxwv ntawm cov roj hmab casters
1) Qhov zoo:
A. Kev nqus plua plav thiab tiv thaiv plua plav: Cov roj hmab yog mos thiab haum rau qhov chaw du xws li cov vuas thiab cov plag tsev ntoo, ua haujlwm zoo buffering vibrations thiab tiv thaiv hauv av.
B. Cov nyhuv txo suab nrov zoo: haum rau cov chaw ua haujlwm, tsev, thiab lwm qhov chaw uas xav tau kev ntsiag to.
C. dav kub adaptability: tswj elasticity txawm nyob rau hauv qis kub.
2) Disadvantages:
A. Kev hnav tsis muaj zog: Kev siv lub sijhawm ntev ntawm qhov chaw ntxhib tuaj yeem ua rau hnav thiab tsim kua muag.
B. Ib qho yooj yim rau lub hnub nyoog: Lub sij hawm ntev raug cov roj thiab hluav taws xob ultraviolet yuav ua rau tawg.
Raws li qhov xav tau tiag tiag, PU feem ntau siv tau ntau dua hauv cov xwm txheej kev lag luam thiab cov roj hmab zoo dua rau qhov chaw nyob hauv tsev.
