Yuav ua li cas hnav-tiv taus yog polyurethane casters?

Kev coj tawm tsam txheeb xyuas ntawm polyurethane casters

Polyurethane casters, vim lawv cov khoom siv khoom, muab cov khoom siv ua kom zoo thiab yog cov ntawv thov sib txuas.

Polyurethane yog cov polymer elastomer, sib txuas nrog elasticity ntawm roj hmab nrog lub hardness ntawm yas nyob rau hauv nws cov qauv molecular. Nws cov coj tsis kam deb deb ntawm cov ntaub ntawv ib txwm muaj xws li roj hmab thiab nylon. Raws li tib lub sijhawm ua haujlwm, kev pabcuam lub neej ntawm polyurethane casters yog feem ntau 3-5 zaug uas ntawm ntuj hloov roj hmab nlon blolon.

Hauv kev siv cov kev siv, cov hnav tsis kam ntawm polyurethane casters yog xav txog hauv ntau qhov:

Ua ntej, lawv muab muaj zog tsis kam rau kev sib txhuam hnav. Txawm hais tias tom qab lub caij nyoog dov ntawm cov nplaim taws (xws li pob zeb ua thiab tiled plag tsev), cov nplaim yog tsawg dua li khawb lossis khawb av.

Thib ob, lawv muab kev cuam tshuam zoo heev coj tau kev coj tsis kam. Thaum nqa cov kev cuam tshuam hnyav, cov kev cuam tshuam instantaneous quab yuam tau tsim los ntawm lub log hu rau hauv av tsis ua rau nkees sai dua hnav.

Thib peb, lawv muaj nyob ruaj khov rau kev coj noj coj ua, muab cov roj ntsha tsis zoo rau cov roj, kua qaub, thiab alkalis, txo kev coj los ntawm kev siv tshuaj corrosion. Txawm li cas los xij, nws cov kev coj tawm tsam yog cuam tshuam cuam tshuam ntau los ntawm hardness. Polyurethane casters nrog lub hardness ntawm 85A-95A muaj kev sib npaug ntawm yooj yim yooj thiab hnav tsis kam, ua rau lawv haum rau feem ntau cov chaw. Thaum super-nyuaj polyurethane (95a thiab siab dua) muaj kev txhim kho cov hnav tsis kam, nws tseem yuav txo qis dua thiab tuaj yeem hnav cov chaw tsis sib xws.

Zuag qhia tag nrho, polyurethane casters, vim lawv cov kev coj hnav tsis zoo, yog siv tshuab, thiab lwm yam khoom siv tau, ua kom muaj zog ua haujlwm ntev, ua tau ruaj khov nyob rau ntau yam kev ua haujlwm.
