Qhov zoo thiab qhov tsis zoo ntawm Polyurethane Casters

Polyurethane Caster Qhov Zoo thiab Qhov Tsis Zoo
Polyurethane (PU) Cov Khoom Siv tau siv dav hauv ntau yam kev thov vim lawv cov khoom siv, tab sis lawv kuj muaj qee qhov kev txwv. Lawv cov txiaj ntsig tshwj xeeb thiab qhov tsis zoo yog raws li hauv qab no:

I. Cov ntsiab lus zoo
Huab cua thiab corrosion Kuj: Polyurethane muaj qhov tsis kam ua roj, cov acids tsis muaj zog, thiab cov kuab tshuaj. Nws tuaj yeem tiv thaiv cov roj muaj roj oily thiab noo ib puag ncig ntawm cov khoom noj ua haus, nrog rau tshuaj nres hauv kev muaj chaw. Nws tseem tiv taus cov hydrolysis thiab tawg vim ntev- ntu kev sib cuag nrog dej, ua rau nws haum rau ntau cov ntawv thov.

Kev tu huv thiab yooj yim los ntxuav: tus du, tsis yog {0} porous} Cov plua plav yooj yim, cov khib nyiab zaub mov, lossis av. Kev ntxuav tu kom tsuas yog so lossis yaug. Qee tus PU CASTERS ntsib cov zaub mov- qib ntawv pov thawj xws li FDA thiab EU 10/2011, ntsib kev nyiam noj ntawm cov zaub mov thiab kev lag luam hauv tsev muag tshuaj.

Kev nqus tau zoo thiab ntsiag to: nrog elasticity zoo, lawv tuaj yeem siv cov khoom siv Cushion thaum lub sijhawm dov, tiv thaiv cov khoom ntsuas ntsuas lossis cov khoom lag luam tsis yooj yim. Lawv kuj ua cov yeeb yaj kiab tsawg, ua rau lawv haum rau cov suab nrov- rhe cov pej xeem xws li kev cob qhia thiab chaw ua hauj lwm. Balanced Load - bearing thiab hnav {}}}- cov kabmob muaj txiaj ntsig piv rau cov khoom siv roj hmab. Lub log saum npoo yog tseem hnav - tiv taus thiab tsawg dua rau deformation, ua rau muaj kev pab cuam lub neej ntev dua li cov roj hmab zoo tib yam, txo cov nqi hloov roj hmab zoo tib yam.

Zoo nkauj pem teb kev hloov tau zoo: lub log nto muaj kev sib txhuam me me thiab cov vuas tsis pub dhau los ntawm cov chaw tsis sib luag yam tsis muaj kev sib tsoo lossis jamming.

Ii. Loj Deadvantages
Cov neeg txom nyem siab - tsis kam: Cov pob kws ua haujlwm polyurethane feem ntau ua haujlwm ntawm -20 ° C thiab 80 ° C. Ntev ntev li cas kub (xws li ze rau ncu) tuaj yeem ua rau muag muag, deformation, thiab txawm muaj ntxhiab tsw tau yooj yim.

Kev nyuaj siab rau cov tawv me me hauv qis - Qhov chaw nres tsheb loj, thiab txawm tias ua rau tawg rau hauv lub log nto. Qhov no ua rau nws tsis phim rau cov ntawv thov xws li khoom txias.

Cov roj hmab siab dua: piv nrog cov roj hmab zoo tib yam thiab cov txheej txheem raw thiab cov khoom siv ntau lawm, thiab cov chav tsev feem ntau yog 30% {{}} 50% siab dua. Rau cov nplai loj batch siv cov xwm txheej, tus nqi ua ntej yuav nce nqi.
