Cov Roj Hmab Puas Muaj Peev Xwm Siv Tau Nyob Rau Hauv High -} Qhov chaw ib puag ncig?

Txawm roj hmab casters tuaj yeem siv tau rau hauv high - qhov chaw ib puag ncig nyob ntawm cov khoom siv roj hmab tsis kam ntawm cov roj hmab khoom. Cov roj hmab sib txawv tau sib txawv cov cua sov tiv taus canabilities, yog li nws nyuaj rau dav dav. Qhov no nyob ntawm cov khoom siv tshwj xeeb thiab kev ua haujlwm ntsuas kub:

 

1. Cov roj hmab dog dig (cov roj hmab zoo li cas, styrenee - butadiene roj hmab): tsis haum rau siab-}}}}}}}}}}} kub ib puag ncig
Cov roj hmab ntuj thiab styrene - butadiene roj hmab yog cov khoom siv roj hmab ntau tshaj plaws. Lawv txoj kev txwv sab sauv rau cov cua sov tsis kam yog qhov tsawg heev, feem ntau tsuas muaj peev xwm tiv taus kub ntawm -20℃thiab 80 degree.

 

Thaum pawg neeg kub tshaj 80 degree, cov khoom muag sai sai, poob rau hauv qhov muaj peev xwm loj dua thiab nce rolling tsis kam.

 

Kev nthuav tawm ntxiv rau qhov kub tshaj 80℃(xws li lub rhaub dej) accelerates roj hmab laus, thiab kev pheej hmoo ntawm lub log poob tawm.

 

These casters are only suitable for use indoors at room temperature (such as office carts and household trolleys) and are completely unsuitable for high-temperature environments.

 

2. Cua sov- Cov roj hmab resistant (urlene}
Qee cov rub tawm tshwj xeeb tuaj yeem tiv thaiv ntau dua qhov kub thiab txias dua thiab tsim nyog rau kev siv nrog kev ntsuas kub muaj pes tsawg

 

Nitrile {{0- butadiene roj hmab: muaj cov roj kub zoo tshaj plaws ntawm kwv yees li 120℃(tuaj yeem tiv taus 150℃rau lub sijhawm luv). Haum rau cov ntawv thov uas yuav tsum tau ua cov roj tsis kam thiab ntsuas kub hauv qab 120 5} {- qhov chaw ib puag ncig ze cov cuab yeej nyob ze cov cuab yeej nyob ze tshuab cov cuab yeej).

 

Ethylene propylene diene diene cov roj hmab siv roj hmab (EPDM): Muaj cov huab cua zoo heev, tuaj yeem tiv taus 180℃rau lub sijhawm luv luv), thiab tawm tsam kev laus ntawm cov kev laus siab. Tsim nyog rau sab nraum zoov daim ntawv thov nrog cov kev siv hluav taws xob kub lossis sab hauv tsev nrog cov chaw kub qis hauv qhov chaw sov (xws li cov chaw nyob sab nraum zoov ntawm cov khoom noj qhuav).

 

Txawm li cas los xij, thov nco ntsoov: Hom roj hmab no tsis tuaj yeem tiv taus ntau kub siab. Tshaj li qhov kev txwv kub no tuaj yeem ua rau muaj kev tsis ua tiav thiab txheej txheem txheej txheem.

 

3. Siab {{- kub {2} {>> Cov roj hmab tshwj xeeb): fluorone roj hmab, fluorone- qhov chaw kub thiab txias.
Rau kev siv nyob rau hauv huab siab high - {degree (xws li ib puag ncig ovrement, thiab siab} roj hmab ua los ntawm silicone roj hmab lossis fluororubber:

 

Silicone roj hmab: Cov khoom kub uas tau muaj ntau yam yog {}} 60℃{6} {degree thiab} kub txog rau 300℃rau lub sijhawm luv luv. Lawv tswj kev elasticity zoo heev, tiv taus kev laus, thiab tso tsis muaj tshuaj phem. Lawv tsim nyog rau siab - sov daim ntawv thov nyob rau hauv bakery khw thiab thauj cov cuab yeej kub siab hauv chav kom tsis muaj menyuam).

 

Fluororubber (FKM): Muaj ntau dua cov cua sov tiv taus, nrog ib qho kub siab tshaj plaws ntawm 200℃rau 260 degree. Lawv tuaj yeem tiv taus kub tshaj 300℃rau lub sijhawm luv luv. Lawv kuj tseem tiv taus tshuaj corrosion (acids, alkalis, thiab cov kuab tshuaj uas muaj cov tshuaj tua hluav taws xob thiab cov khoom siv kub nyob rau hauv high- kub cov ntaub ntawv hauv metallurgical kev cob qhia).

 

Xaus: Xaiv cov khoom siv roj hmab raws li qhov ntsuas kub.
Yog tias qhov kub thiab txias yog tsawg dua li 80℃(li qub / nruab nrab roj hmab, thiab huab cua thiab huab cua tsis yog thawj qhov kev txiav txim siab.

 

Yog tias qhov kub tau kub yog 800℃(nruab nrab / siab kub): Xaiv kub / roj nitrile roj hmab (roj {{resistant) lossis EPDM casters.

 

If the ambient temperature is >150 Qib (siab / pheej yig siab):: Xaiv cov roj hmab silicone lossis tshuaj xyuas cov fluorone lossis tshuaj xyuas cov tshuaj fluorublub.

 

Ib qho ntxiv, hauv high - Cov khoom siv kub los tiv thaiv cov khoom siv kub thiab cov log tsheb) kom tsis txhob muaj lub log high - kev kub ntxhov.
