Polypropylene Multifilament: Cov qauv kev lag luam thiab kev siv ceev faj

Qhov zoo ntawm polypropylene multifilament yuav tsum ua raws li cov qauv hauv tebchaws (xws li GB / T 17640-2008) lossis cov qauv kev lag luam cuam tshuam. Cov kev ntsuas tseem ceeb muaj xws li linear density deviation, breaking zog, thiab elongation thaum so. Cov ntsiab lus tseem ceeb rau kev siv suav nrog:

Kev txwv kub: Polypropylene muaj qhov melting point tsawg (kwv yees li 165 degree); Lub sij hawm ntev raug rau qhov kub siab yuav ua rau cov khoom deformation lossis kev ua haujlwm degradation.

 

UV Resistance ​: Ntev - lub sij hawm sab nraum zoov raug yuav tsum tau ntxiv ntawm UV stabilizers los tiv thaiv kev laus thiab embrittlement.
Kev sib raug zoo: Kev sib cuag nrog qee yam tshuaj (xws li cov tshuaj oxidizing muaj zog) tuaj yeem ua rau muaj kev cuam tshuam; kev ntsuam xyuas compatibility yuav tsum tau ua ua ntej.
