Wet Aramid Pulp

Cov txheej txheem ntau lawm thiab cov yam ntxwv ntawm tus qauv

Txhawm rau txhim kho kev sib cais thiab kev sib xyaw ua haujlwm, ntub aramid pulp yog ib qho tshwj xeeb kho aramid reinforcing khoom ua los ntawm fibrillation hauv dej -raws li qhov system. Ib qho kev tsim kho heev, fibrillated qauv yog tsim thaum aramid fibers raug txiav, ua kom zoo, thiab raug tshem tawm hauv dej thaum lub sijhawm tsim khoom. Txoj kev no tsim cov khoom siv pulp nrog kev sib txuas txuas ntxiv ntawm microfibres thiab cov khoom zoo dispersion, uas ua rau nws tsim nyog rau cov ntawv thov xav tau kev sib xyaw txhim khu kev qha.

Core Performance thiab Reinforcement Mechanism

Nthuav aramid pulp lub peev xwm los muab cov yam ntxwv ua tau zoo dua qub nrog cov yam ntxwv zoo ntawm para-aramid fibers yog ib qho ntawm nws cov yam ntxwv tseem ceeb. Kev sib txuas zoo dua nrog roj hmab, resin, thiab lwm yam kev sib xyaw ua ke yog ua tau los ntawm cov qauv fibrillated microfibre, uas nthuav dav thaj chaw sib cuag ntawm cov ntaub so ntswg thiab cov khoom siv matrix. Lub pulp pab txhawb rau cov khoom ruaj khov, viscosity tswj, thiab ntxiv dag zog thaum lub sij hawm shear processing.

Cov ntawv thov kev lag luam thiab cov khoom zoo

Wet aramid slurries yog ntxiv rau cov khoom siv roj hmab, cov khoom sib khi, thiab cov khoom sib txhuam los txhim kho lawv txoj haujlwm. Automotive nres ncoo, gaskets, clutch cov ntaub ntawv, tsav siv, thiab lwm yam khoom lag luam uas yuav tsum tau resistant rau tshav kub, hnav, thiab mechanical stress siv nws. Ntev - lub sij hawm cov khoom ua tau zoo yog khaws cia thiab durability yog nce vim mus rau lub pulp tsim.

Lub℃ntawm fibrillation thiab fiber ntev xaiv yuav hloov tau los hloov cov ntaub ntub dej cov yam ntxwv.

Raws li cov kev qhia tshwj xeeb uas tam sim no muaj, cov txiaj ntsig raug suav nrog qhov nruab nrab fiber ntau ntev ntawm 0.6-1.4 hli, thaj chaw tshwj xeeb ntawm thaj tsam li ntawm 7-15 m² / g, thiab thermal disintegration kub ntawm kwv yees li 550℃rau qee qib. Cov yam ntxwv no tso cai rau cov neeg tsim khoom xaiv cov qib zoo raws li cov txheej txheem ua tiav thiab cov hom phiaj ua tiav cov khoom kawg.

Cov ntaub ntub dej aramid sib cuam tshuam ntau dua nrog cov matrix ib puag ncig thiab muaj cov qauv fiber ntau dua li cov khoom siv fiber ntau. Nws yog qhov tsim nyog rau cov ntawv thov kev lag luam zoo xws li cov ntaub ntawv sib txhuam, cov tshuab sealing, cov ntaub ntawv tshwj xeeb, thiab cov khoom sib xyaw ua ke vim nws qhov zoo tshaj plaws dispersion, muaj peev xwm txhawb zog, thiab ruaj khov thermal zog.
