Cov Yeeb Nkab Hlau Polyurethane
Cov yeeb nkab hlau uas muaj polyurethane yog cov khoom siv kav dej uas tiv taus kev hnav, uas siv dav hauv cov kav dej ua cov khoom siv hauv av thiab cov kav dej xa mus rau cov khoom siv tailing. Cov chaw tsim hluav taws xob fossil-fuel siv cov kav dej rau cov tshuab tshem tawm thee thiab tshauv, nrog rau cov roj, tshuaj lom neeg, cement thiab cov khoom lag luam nplej.
Cov yam ntxwv
1. Hnav-resistant
2. Tiv thaiv kom tsis txhob muaj qhov loj me
3. Kev Tiv Thaiv Kev Xeb
4. Kev tiv thaiv kev laus ntawm hydrolysis
5. Kev ywj pheej siab
6. Kev Tiv Thaiv Kev Poob Siab ntawm Mechanical
7. Kev siv lubrication rau tus kheej
Arex xaiv cov khoom siv zoo tshaj plaws nrog rau txoj kev hloov kho nano los txhawb cov khoom siv polyurethane. Nws ua rau cov khoom polyurethane lined nrog cov qauv tshuaj ruaj khov dua thiab qhia txog nws qhov kev hloov pauv hauv qhov xwm txheej ua haujlwm.
Cov yeeb nkab polyurethane lined steel, ua ib qho ntawm cov khoom lag luam hauv tsev ntawm Arex, nrov thiab siv los ntawm peb cov neeg siv khoom mining.
