Xov xwm

Cov yeeb yaj kiab yas feem ntau ntsib qhov tsis txaus ntseeg uas cuam tshuam rau kev tsim khoom, kev hloov pauv, thiab kev siv kawg. Cov cuab yeej ntuj no ua rau kev ua haujlwm nyuaj, uas cuam tshuam kev ua haujlwm. Slip additives tau tshwm sim los ua ib qho tseem ceeb hauv kev daws cov teeb meem no, txhim kho kev tsim cov yeeb yaj kiab, thiab txhim kho kev ua haujlwm. Tsab ntawv xov xwm no delves rau hauv kev tshawb fawb ntawm cov khoom qab zib ntxiv thiab muab cov tswv yim daws teeb meem rau kev tsim cov yeeb yaj kiab Polyolefin.

Kev nkag siabSlip Additives: Lawv Yog Dab Tsi thiab Lawv Ua Haujlwm Li Cas?

Slip additives yog cov sib txuas tshwj xeeb ua ke rau hauv cov yeeb yaj kiab yas los txo cov coefficient ntawm kev sib txhuam (COF), ua rau kev ua haujlwm zoo dua thiab ua haujlwm zoo dua. Kev txo qis COF yog qhov tseem ceeb rau kev tiv thaiv cov teeb meem xws li cov yeeb yaj kiab jamming, yooj yim ntawm kev tuav, thiab txhim kho lub tshuab ua haujlwm. Ntawm no yog ib qho kev sib faib ntawm cov nplaum nplaum ntxiv thiab lawv cov txiaj ntsig tseem ceeb:

Kev poob qis: COF 0.50-0.80 (200-400 ppm cov ntsiab lus hauv qab)

Nruab Nrab Slip: COF 0.20-0.40 (500-600 ppm cov ntsiab lus hauv qab)

High Slip: COF 0.05-0.20 (700-1000 ppm hauv qab cov ntsiab lus)

Yuav ua li casSlip AdditivesKev Ua Haujlwm: Kev Tshawb Fawb Tom Qab Kev daws teeb meem

Slip additives ua haujlwm los ntawm ob lub ntsiab mechanisms:

Migration-Based Mechanism: Thaum xub thawj dispersed thoob plaws hauv lub polymer matrix, plam additives migrate rau saum npoo ntawm zaj duab xis thaum nws txias. Qhov kev tsiv teb tsaws no tsim cov txheej txheem lubricating uas txo cov kev sib txhuam, txhim kho kev ua yeeb yaj kiab.

Surface Orientation: Raws li cov nplaum nplaum molecules ncav cuag zaj duab xis nto, lawv ua raws li ib qho kev taw qhia tshwj xeeb. Piv txwv li, fatty amides npaj lawv tus kheej nrog hydrocarbon chains embedded nyob rau hauv lub polymer, thaum cov pab pawg amide ntsib sab nraud. Cov qauv no txo ​​qhov kev sib txhuam ntawm qhov chaw thiab ua kom yooj yim rau kev ua haujlwm.

Migration Kinetics thiab Performance Over Time

Slip additives nthuav tawm tus cwj pwm nyob ntawm lub sijhawm, lub ntsiab lus ntawm COF txo qis zuj zus mus rau lub sijhawm:

Theem 1 (0-24 teev): Kev tsiv teb tsaws chaw nrawm nrog kev txo COF tseem ceeb.

Theem 2 (24-72 teev): Kev tsiv teb tsaws nruab nrab txuas ntxiv, muab kev txo qis COF ruaj khov.

Theem 3 (3-10 hnub): Equilibrium mus txog nrog stabilized COF.

Kev nkag siab txog cov theem no yog qhov tseem ceeb rau kev tswj kom zoo thiab kev teem caij tsim khoom.

Hom ntawmSlip Additives: Xaiv qhov zoo tshaj plaws haum rau koj daim ntawv thov

Cov khoom sib txawv ntawm cov nplaum nplaum muaj ntau yam kev ua tau zoo. Kev xaiv ntawm additive nyob ntawm qhov kev xav tau ntawm kev ua haujlwm thiab cov txiaj ntsig xav tau:

Migratory Slip Additives: Kev tsiv teb tsaws sai, raug nqi zoo, zoo tagnrho rau kev ua haujlwm qis. Piv txwv li: Oleamide, stearamide.

Non-Migratory Slip Additives: Kev ua haujlwm tsis tu ncua, haum rau kev ua haujlwm kub. Piv txwv li: Silicone-based additives, fluoropolymer-based additives.

Fatty Acid Amides: Siv dav rau cov yeeb yaj kiab polyolefin, muab kev txo qis COF zoo yam tsis muaj kev cuam tshuam qhov pom kev pom tseeb.
