Cov Roj Hmab Puas Tau Siv Tau Hauv Tsawg -} qhov chaw ib puag ncig?

Seb cov roj hmab casters tuaj yeem siv rau hauv qis - qhov chaw ib puag ncig nyob tau nyob ntawm qhov tseeb - kub kuj ntawm cov khoom siv roj hmab. Cov roj hmab sib txawv tau sib txawv tsawg - kub tsis kam muaj peev xwm, yog li cov dav dav dav dav tsis tuaj yeem ua:

1. Cov roj hmab dog dig (cov roj hmab zoo li cas, Styrene - butadiene roj hmab): tsis haum rau qis-}}}}}}}}}} qhov chaw ib puag ncig tsawg
Cov roj hmab ntuj thiab styrene - butadiene roj hmab yog cov khoom siv roj hmab ntau dua, feem ntau tsuas yog tiv thaiv cov kub ntawm-16℃thiab 80 degree.
Thaum lub caij nyoog kub poob qis dua -10 degree, cov khoom siv maj mam ua thiab poob nws lub peev xwm poob siab. Thaum cov tee ntsuas kub hauv qab-20 degree, nws tiav nreeg thiab nquag mus "stuttering" thaum lub sijhawm dov, thiab txawm tawg thiab poob kev cuam tshuam nrog kev cuam tshuam me.
Kev nthuav tawm txuas ntxiv mus rau qhov kub hauv qab no-} 20℃(ua kom nrawm dua roj hmab, ua rau sab nraud cov qauv roj hmab thiab ua rau poob haujlwm tam sim ntawd. Lub log tsis muaj log tread kuj tseem tuaj yeem ua rau muaj kev poob sai rau hauv kev thauj khoom {{}} ecing kev nyab xeeb kev phom sij. Hom kev sib xyaw ua ke tsuas yog tsim nyog siv nyob rau hauv qhov chaw ua haujlwm kub ib puag ncig thiab tsev neeg trolleys) thiab yog kiag li tsis haum rau cov chaw tsawg-kub.

2. Low-Temperature-Resistant Rubber (Nitrile-Butadiene Rubber, Ethylene Propylene Diene Rubber): Suitable for mild low-temperature environments
Qee qhov tshwj xeeb rubbers tuaj yeem tiv thaiv qee qhov tsis tshua muaj siab thiab yog qhov tsim nyog rau cov me me qis - Cov ntawv thov kub:
Nitrile - butadiene roj hmab: zoo heev {degree rau -30℃txwv, thiab muaj feem ntau ruaj ntseg nqus nqus dej khov kho thiab dov lub zog. Nws yog qhov tsim nyog rau cov ntawv thov uas xav tau cov roj tsis kam thiab kub siab tshaj plaws nyob rau hauv qis-kub tshuab khw thiab khoom txias ua tsis tau khaub ncaws).
Ethylene diene cov roj hmab roj hmab (EPDM): Cov huab cua zoo heev thiab tsis tshua muaj cua txias, muaj peev xwm tiv thaiv} 50℃ntawm tsawg kub, thiab kev ua pov thawj muaj zog kev laus. Nws yog qhov tsim nyog rau kev siv sab nraum zoov me me-} kev ua haujlwm sab nraum zoov tam sim no) lossis hauv cov kev cob qhia tsawg (-20℃rau -40 degree).

3. High {{-}} Cov roj hmab resistant (silicone roj hmab, haum rau kev siv qis eps- kev siv kub
Rau kev siv nyob rau hauv tsawg heev - qhov chaw nyob hauv qab no, thiab xaiv tshwj xeeb roj hmab
Roj hmab Silicone: qhov qis qis - 60 degree, nrog qee qhov siab {degree tau muaj peev xwm nrog kev kub siab li -80 degree. Cov khoom siv no tau ua kom zoo dua qub thiab poob siab khaus txawm tias thaum tsis tshua muaj qhov kub tsawg, tsis tas muab cov tshuaj tsis zoo. Lawv tsim nyog rau cov ntawv thov xws li kev sib sib zog nqus txias rau cov zaub mov (-40 Qib rau-cov khoom siv kho mob) thiab qis dua
Hloov Kho EPDM: los ntawm cov mis los ntawm qhov ua kom zoo dua, cov khoom ua kom zoo dua tuaj yeem txo rau {Qib rau -60 Kev Kawm Ntawv, Thaum Ua Haujlwm Tsis Txaus Siab ntawm EPDM. Qhov no ua rau lawv haum rau kev siv sab nraum zoov nyob rau hauv cov chaw txias txias heev (piv txwv li cov tsheb thauj khoom sab nraud) lossis tsawg cov kab lag luam sab qaum teb (-30℃rau -50 degree).

Xaus: Xaiv cov roj hmab cov khoom siv raws li qhov qis - qhov kub.
Yog tias qhov kub tshaj plaws yog ntau dua lossis sib npaug ntawm -10℃(stander nitrile roj hmab thiab EPDM casters tuaj yeem siv, nrog cov roj ua tsis tau zoo ua ntej.
Yog tias qhov kub thiab txias yog nruab nrab ntawm- 10℃thiab {degree-} -30 degree) lossis qib epdm casters (saum -40 degree) yuav tsum tau xaiv.
Yog tias qhov cua sov yog <{- 40℃yuav tsum tau xaiv, thiab cov khoom lag luam EPDM lossis cov khoom lag luam tsis kam (kom tsis txhob muaj tus lej tsis muaj tseeb).
Ib qho ntxiv, hauv qhov qis - Cov khoom siv tsis yooj yim los ntawm cov khoom siv me me lossis cov log tsis txaus ntseeg los ntawm kev kub siab lossis kub}} Txheej txheem txheej txheem tag nrho yog haum rau tsawg- tej yam kev mob kub.
