Puas yog tus ntaus nqi thauj khoom muaj peev xwm ntawm Polyurethane Casters cuam tshuam los ntawm qhov kub?

Tus ntaus nqi thauj khoom muaj peev xwm ntawm Polyurethane Casters yog cuam tshuam ntau ntawm qhov kub. Tus thawj coj yog tias lub zog ntawm polyurethane (hardness, thiab elasticity, thiab elasticity, thiab elasticity) hloov nrog qhov ntsuas kub, ua kom txo qis hauv kev thauj khoom muaj peev xwm lossis tsis ua tiav. Cov kev cuam tshuam tshwj xeeb cuam tshuam thiab kev tshwm sim muaj raws li hauv qab no:

1. Ib puag ncig kub (saum 80 degree): rated load muaj peev xwm txo qis
Lub surlert ntsuas kub txwv rau cov ntaub ntawv polyurethane yog kwv yees li 80 degree. Thaum pawg neeg kub tshaj qhov ntau no, cov khoom muag muag thiab nws cov qauv molecular reles, ua kom tsawg hauv load muaj peev xwm:

TSHWJ XEEB:
Thaum qhov kub nce mus rau 80-120 degree, lub hardness (ntug dej a) ntawm polyurethane tee los ntawm 40-60 ntug dej ib, tsis muaj zog rau deformation. Piv txwv li, lub voj voog qub ntsuas rau 300kg tej zaum muaj qhov muaj peev xwm muaj peev xwm ntawm 150-200kg. Yog tias tus thawj ntaus nqi yog tseem siv tau, lub log lub log yog nquag nquag yog kho hniav, plhaw, lossis txawm sib cais ntawm lub log tsheb.

Thaum qhov ntsuas kub tshaj ntawm 120 degree, polyurethane yuav cuam tshuam bermesy, ua rau lub log tread los ua cov nplaum thiab tawg. Txij ntawm no, lub tawb nqa khoom lub tawb - tus xeeb ceem muaj yeej tseem ceeb ploj. Kev siv txuas ntxiv yuav tsis tsuas yog ua rau lub zog ua kom puas, tab sis kuj ua rau cov khoom siv los qhia txog lub log tawg.

Typical scenarios include food processing areas near ovens and boilers, logistics transfer operations exposed to the summer sun, and high-temperature drying workshops.

2. Feem ntau kub (hauv qab -20 degree): indirect txo nyob rau hauv rated load muaj peev xwm
Thaum temperatures poob qis dua - 16 degree, polyurethane cov khoom siv hloov ntawm ib lub xeev elastic rau lub xeev me ntsis. Thaum nws hardness nce (ntug dej hiav txwv tshaj 100), nws cov kev cuam tshuam tsis zoo thiab txo qis kev nyab xeeb "ntawm cov nqi thauj khoom muaj peev xwm.

Cov kev cuam tshuam tshwj xeeb:
Thaum cov khoom siv tau nkig, lub log poob nws lub peev xwm cushioning. Qhov hnyav, uas yuav txwv tsis pub dhau los ntawm elasticity, tam sim no muaj kev xav ntawm thaj chaw hauv zos ntawm lub log nto. Txawm hais tias lub nra tsis tshaj li tus nqi rated, muaj kev nyuaj siab ntau dhau los ua rau lub log nto rau tawg lossis tawg.

Ntawm qhov kub tsawg, cov kabmob cov roj yuav ua tau zoo, nce kev ua kom tau ntau dua thiab xav tau ntau lub zog rau cov khoom siv thawb. Qhov kev cuam tshuam ntxiv no ntxiv txo cov tais lub tawb rau cov khoom siv tiag tiag - cov kabmob kev nyab xeeb. Piv txwv li, rau 200kg {- tso rau hauv ib -30 teev ib puag ncig, nws raug pom zoo tias lub nra tiag tsis tshaj 120-150kg kom tsis txhob muaj log tawg.

3. Ib puag ncig cua sov (- 20℃-80 degree): rated load-bearing muaj peev xwm feem ntau ruaj khov.
Tsis pub dhau lub polyurethane khoom siv "ntau yam ua haujlwm kub siab" ({}}} 80}), nws lub zog, thiab elasticity nyob ruaj khov. Lub tais diav lub nraaj-cov kabmob tau sib phim cov lus teev tseg, tsis tas yuav tsum txo cov khoom siv thauj khoom ntxiv.

Txawm li cas los xij, thov nco ntsoov: txawm tias yog cov ntsuas kub, yog tias muaj kuab lom thiab kev tu cov khoom lag luam kom tsawg hauv cov khoom lag luam {{bearing} cov kabmob muaj peev xwm).

Cov ntsiab lus: Cov lus pom zoo tseem ceeb rau kev cuam tshuam kub
Prioritize temperature-matching scenarios: If operating in high-temperature (e.g., >80 degree) lossis tsawg - kub (piv txwv li,<-20°C) environments, choose high- and low-temperature-resistant modified polyurethane casters (e.g., glass-fiber-reinforced polyurethane with a high-temperature resistance of 120°C, or elastomeric polyurethane with a low-temperature resistance of -40°C). The load rating will be re-marked based on the modified material properties; please refer to the product specifications for details.

Ua kom muaj kev kub ntxhov heev: yog tias cov tub cas polyurethane yog siv ib puag ncig ib ntus rau lawv, nws raug pom zoo kom txo tau cov nqi thiab cov sijhawm siv tsawg dua.

Nquag xyuas seb qhov kev cuam tshuam kub: nyob rau hauv ib puag ncig nrog loj chain compressions (piv txwv li kub), tshuaj xyuas lub log ntawm kev muag muag, embittlement, lossis tawg. Hloov cov tub rog uas puas tsuaj kom tsis txhob muaj kev phom sij kev nyab xeeb.
