Qhov txawv ntawm Polyurethane Caster Log thiab Roj Hmab Caster Log

Txhim kho casters ntawm qee lub txee txawb tuaj yeem txav tau yooj yim. Muaj ntau hom casters, xws li nylon casters, roj hmab casters, thiab polyurethane casters. Yog li, dab tsi yog qhov txawv ntawm polyurethane casters thiab roj hmab casters?
1. Lub peev xwm thauj khoom
Cov roj hmab hnyav hnyav muaj peev xwm thauj khoom ntawm ib ncig ntawm 300-400kg thiab tsis muaj zog tiv thaiv kev tawg thiab tawg. Lub peev xwm thauj khoom ntawm polyurethane casters yog kwv yees li ob zaug ntawm cov roj hmab casters. Polyurethane casters muaj kev tiv thaiv zoo heev rau kev loj hlob tawg, tsim kua muag, thiab tiv thaiv oxidation zog, nrog rau kev hnav zoo.
2. Hauv av imprint
Thaum siv cov roj hmab log, nws yog ib qho yooj yim kom tawm cov pa roj carbon dub rau hauv av. Cov tshuaj lom neeg muaj pes tsawg leeg ntawm cov ntaub ntawv polyurethane txiav txim siab tias polyester casters yuav tsis tawm cov qhab nia rau hauv av, thiab txawm tias cov xim ci ntsa iab yuav tsis tawm ntawm cov xim pleev xim rau hauv av.
3. Kev laus ua haujlwm ua haujlwm
Roj hmab casters uas tuaj rau hauv kev sib cuag nrog cov kuab tshuaj organic rau lub sijhawm ntev yog qhov ua rau o, uas ua rau lawv cov kua muag tsis muaj zog thiab tsis kam mus rau chipping. Txawm hais tias polyurethane casters raug rau cov kuab tshuaj no ntev, lawv cov khoom sib txawv yuav nyob twj ywm tsis hloov thiab lawv yuav tsis corrode lub log.
4. Hardness thiab resilience
Lub Shore A hardness ntawm roj hmab log feem ntau yog nyob nruab nrab ntawm 67-75 degrees, uas yog kuj tsawg. Lub hardness ntawm polyurethane log yog siab li 83-95 degrees. Nyob rau hauv qhov kev nyab xeeb ntawm kev nyab xeeb, siv polyurethane casters tuaj yeem ua kom muaj peev xwm buffering, thaum tseem muaj peev xwm thauj khoom siab thiab tsis tshua muaj zog. Lub hardness thiab rebound kev ua tau zoo ntawm polyurethane log tuaj yeem hloov kho raws li cov neeg siv khoom xav tau thiab kev siv ib puag ncig.
5. Castor raw khoom
Roj hmab log ntau lawm yog qhov ua rau muaj kuab paug thiab muaj kev ua haujlwm tsawg. Cov khoom siv raw tuaj yeem sib xyaw nrog cov khoom siv rov ua dua tshiab, thiab tej zaum yuav muaj ntxhiab tsw. Cov polyurethane casters muaj cov kev xav tau siab rau lub log nto, siv cov khoom siv raw yam tsis muaj ntxhiab tsw, thiab tsis tuaj yeem sib xyaw nrog cov khoom siv raw.
