Qhov twg kub-kub-resistant additive yog cov txiaj ntsig zoo tshaj plaws rau kev txhim kho kev ua haujlwm ntawm PP casters?

Iav cov fiber ntau cov thawv thiab cov tshuaj tua hluav taws kub yog ob qho txiaj ntsig zoo tshaj plaws rau kev txhim kho lub siab-kub tsis kam ntawm pp (polypropylene) casters. Iav cov fiber ntau cov nyhuv muaj ntau cov nyhuv, tshwj xeeb yog suav rau kev siv hluav taws xob hnyav thiab ntsuas kub. Cov ntsiab lus yog raws li hauv qab no:

1. Iav cov fiber ntau (cov lus pom zoo tseem ceeb)
Cov iav fiber ntau (cov fiberglass) lub cev ua kom cov qauv siv lead ua thiab cua sov ntawm PP, ua rau nws txoj kev tseem ceeb rau kev txhim kho PP lub siab - kub tsis kam.

Cov cua sov deformation kub ntawm unfilled pp tsuas yog 60-80 degree. Ntxiv 10% -30% tws iav fiber ntau nce qhov ntsuas kub rau 120-1-high-high-kub) xws li muag los yog tsaus muag los ntawm kev muag khoom lossis tsaus muag ntawm qhov kub. Ib txhij ua tau zoo dua cov khoom siv kho tshuab: cov fiber ntau fiber ntau, cuam tshuam, thiab txo lub peev xwm ntawm lub peev xwm ntawm kev kub. Qhov no ua kom sawv daws yuav khaws lawv cov duab thiab xaim tsis kam txawm tias nyob rau hauv high-kub, xws li nyob rau hauv rhiav cov ntaub ntawv tsheb).

2. High-efficiency antioxidant (Key AuXiliary)
PP yog raug rau cov thermal oxidation ntawm qhov kub, ua rau molecular chart breakage, laus, thiab emnitzing. Antioxidants tuaj yeem qeeb cov txheej txheem no, ua kom muaj kev kub siab ntev-kub.

Hom Hom: Hindered Phenolic thawj cov tshuaj antioxidants (xws li phosphite theem nrab antioxidants (xws li 168). Cov antioxidant inhibit dawb radical chainion cov tshuaj tivtaug thiab txo cov oxidative tsis deb ntawm qhov kub.

Cov nyhuv: thaum siv cov antioxidants ib leeg yuav tsis muaj kev cuam tshuam txog kev sib tw kub (xws li muaj peev xwm tswj hwm kev sib txuas nrog cov kev sib txuas ntev dua vim ntev-sim-kub-kub laus. Cov ntawv thov uas tsim nyog thiab zoo

Rau pp casters, iav fiber muab tub lim (10% -30% muab tub lim) yog qhov ua tau zoo, txhim kho qhov kub thiab txias tsis kam thiab thauj khoom-cov kabmob tsis ruaj khov. Cov tshuaj tua hluav taws kub ua haujlwm tau tiv thaiv ntev, txuas ntxiv ntawm lub neej pabcuam thaum muaj kev kub siab. Kev ua ke ntawm ob qhov kev ua haujlwm ntev ntev nyob rau hauv ib puag ncig ntawm 100-120 degree, thaum tseem ua tau cov kev cai rau kev hnav thiab cuam tshuam.
