FAQ
Q: CR roj hmab ua haujlwm li cas hauv cov ntawv thov sab nraum zoov raug tshav ntuj thiab ozone?
A: CR roj hmab muaj kev tiv thaiv zoo rau UV hluav taws xob thiab ozone degradation. Cov tshuaj antiozonant tshwj xeeb tiv thaiv qhov chaw micro- tawg thaum lub sij hawm ntev - tawm sab nraum zoov.
Q: Dab tsi yog qhov siab tshaj plaws ua haujlwm kub rau cov qauv CR seals?
A: Cov qauv sib txuas ua haujlwm tsis tu ncua ntawm -40℃thiab +100℃. Kev sib cuam tshuam txog li +120℃yog qhov ua tau, txawm hais tias kev ua haujlwm ruaj khov saum toj no +100℃accelerates polymer hardening.
Q: Durometer hardness puas tuaj yeem hloov kho rau qhov tshwj xeeb compression quab yuam?
A: Yog. Compound hardness spans 40 mus rau 85 Shore A. Softer compounds (40-50 Shore A) haum tsawg-kaw-force enclosures, thaum nyuaj formulations (70-85 Shore A) tiv thaiv extrusion nyob rau hauv siab mechanical loads.
Q: Cov ntaub ntawv dab tsi yuav tsum tau pib ua kev cai molded lossis extruded CR foob qhov project?
A: Cov ntawv xa mus yuav tsum muaj 2D engineering kos duab nrog qhov loj me thiab kev ua siab ntev, 3D CAD qauv (STEP / IGES), kev ua haujlwm kub txwv, tshuaj lom neeg cov ntsiab lus, thiab cov ntim txhua xyoo.
Q: Yuav ua li cas koj tiv thaiv qhov seem shrinkage variations thaum lub sij hawm vulcanization?
A: Tooling shrinkage allowance yog xam los ntawm kev sib xyaw polymer sib piv thiab kho qhov kub thiab txias. Tom qab- kho cov kev pab cuam thermal stabilization thiab kev sim ua kom qhov kawg qhov ntev txaus siab ISO 3302-1 kam rau ua.
Q: Cov ntaub ntawv pov thawj dab tsi nrog cov khoom xa tuaj?
A: Txhua qhov khoom xa tuaj suav nrog Daim Ntawv Pov Thawj Kev Ntsuam Xyuas (CoA) txheeb xyuas cov khoom sib tw- tshwj xeeb hardness, tensile lub zog, thiab cov ntaub ntawv elongation, nrog rau RoHS thiab REACH tshaj tawm ntawm kev ua raws.
