ECR Fiberglass Direct Roving rau Pultrusion
Kev Roving Ncaj Qha rau Pultrusion
Kev Roving Ncaj Qha rau Pultrusion yog raws li silane reinforced sizing formulation. Nws muaj kev ncaj ncees zoo,
Sai sai ntub tawm, zoo tiv taus kev sib txhuam, qis fuzz; qis catenary, zoo sib xws nrog polyurethane resin, muab cov khoom siv kho tshuab zoo heev lossis cov khoom tiav.

Kev Roving Ncaj Qha rau Pultrusion
Kev Roving Ncaj Qha rau pultrusion feem ntau yog sib xws nrog cov unsaturated polyester, vinyl thiab phenolic resin systems. Cov khoom Pultrusion yog siv dav hauv kev tsim kho, kev tsim kho, kev sib txuas lus thiab kev lag luam rwb thaiv tsev.
Cov ntaub pua plag roving, cov lev raug rub los ntawm lub dab dej impregnation resin, lub pwm kub, lub cuab yeej rub tas mus li, nyob rau hauv qhov kub thiab txias thiab siab, tom qab ntawd cov khoom kawg tau tsim tom qab txiav-saw.
txheej txheem pultrusion
Pultrusion yog ib txoj kev tsim khoom uas tsim cov duab polymer uas muaj zog nrog rau qhov sib tshuam sib xws. Cov txheej txheem no suav nrog kev siv cov kua roj sib xyaw, uas suav nrog cov roj, cov khoom sau, thiab cov khoom ntxiv tshwj xeeb, nrog rau cov ntaub ntawv txhawb nqa. Hloov chaw thawb cov ntaub ntawv, zoo li ua tiav hauv extrusion, cov txheej txheem pultrusion suav nrog rub lawv los ntawm lub pwm hlau uas tau ua kom sov siv lub cuab yeej rub tas mus li.
Cov khoom siv txhawb nqa siv yog cov khoom siv txuas ntxiv mus, xws li cov yob ntawm cov fiberglass lev thiab cov doffs ntawm fiberglass roving. Cov khoom siv no tau muab tso rau hauv cov tshuaj sib xyaw hauv cov dej da dej resin thiab tom qab ntawd rub los ntawm lub pwm. Cov cua sov los ntawm lub pwm pib cov resin gelation lossis hardening txheej txheem, ua rau cov qauv khov kho thiab kho tau zoo uas phim cov duab ntawm lub pwm.
Tus qauv tsim ntawm cov tshuab pultrusion yuav txawv nyob ntawm seb cov khoom xav tau zoo li cas. Txawm li cas los xij, lub tswv yim yooj yim ntawm cov txheej txheem pultrusion tau piav qhia hauv daim duab qhia hauv qab no.
