Thaum tshav kub kub- teeb tsa tsis
Kev ntsuas kub: Kev tswj qhov kub thiab txias yuav tsum tau khaws cia nyob rau hauv ± 0.5℃ntau yam. Kub deviations ncaj qha hloov cov filament lub crystallinity; Tsis tshua muaj kub ua rau tsis txaus tso tawm ntawm kev ntxhov siab sab hauv, ua rau cov filaments nquag deformation thiab matting thaum siv, thaum kub siab heev ua rau cov khoom embrittlement, ua rau tawg thaum khoov.
Teem sijhawm sijhawm: Lub sijhawm cua sov tsim nyog- teeb tsa lub sijhawm tso cai rau kev teeb tsa tag nrho ntawm cov saw hlau polymer. Kev teeb tsa dual - txheej txheem (dej da dej ua raws li cua kub) tuaj yeem txhim kho filament resilience tuav los ntawm kwv yees li 50%, cuam tshuam rau lub neej qaug zog.
Txoj kev ua kom txias: Kev ua kom txias txias txhawb nqa cov txheej txheem sab hauv crystalline ntau dua, tsis txhob muaj kev ntxhov siab sab hauv uas tshwm sim los ntawm kev quenching sai, thiab tiv thaiv cov pob txha tawg hauv lub sijhawm ntev - siv.
Daim duab txheej txheem tsis
Kos piv: Ib qho kev pom zoo sib piv txhim kho molecular orientation thiab nruj molecular saw entanglement, txhim kho cov filament tsis kam rau khoov thiab ncab thaum txo qis deformation mus tas li nyob rau hauv kev ntxhov siab.
Teeb duab nro: Tension uniformity txiav txim siab qhov kev ua tau zoo ntawm tag nrho cov batch ntawm filaments. Kev sib hloov ntawm qhov nro ntau dhau ua rau cov khoom tsis sib xws ntawm filament -nrog qee cov strands ua mos thiab lwm yam nkig heev - yog li ua rau lub neej ua haujlwm luv luv.
