ECR Fiberglass Direct Roving rau Pultrusion
Direct Roving rau Pultrusion
Direct Roving rau Pultrusion yog raws li silane reinforced sizing formulation. Nws muaj kev ncaj ncees zoo,
Fast ntub tawm, zoo abrasion kuj, tsawg fuzz; qis catenary, zoo sib xws nrog polyurethane resin, muab cov cuab yeej zoo heev los yog cov khoom tiav.
| Khoom Code | Txoj kab uas hla (μm) | Linear Density (tex) | Tau tshaj Resin | Khoom nta & Daim ntawv thov |
| EWT150/150H | 13/14/15/20/24 hnub | 600/1200/2400/4800/9600 | UP/VE/EP | Fast thiab ua tiav ntub-tawm hauv resins Tsawg fuzz Tsawg catenary Cov cuab yeej cuab tam zoo heev |
Direct Roving rau Pultrusion
Direct Roving rau pultrusion feem ntau yog sib xws nrog unsaturated polyester, yas thiab phenolic resin systems. Pultrusion cov khoom siv dav siv hauv tsev, kev tsim kho, kev sib txuas lus thiab kev lag luam rwb thaiv tsev.
Lub roving, mats yog rub los ntawm ib tug resin impregnation da dej, rhuab tuag, nruam rub ntaus ntawv, nyob rau hauv lub kub kub thiab siab siab tej yam kev mob, ces zaum kawg cov khoom yog tsim tom qab cutoff-pom.
txheej txheem pultrusion
Pultrusion yog cov txheej txheem tsim khoom uas ua kom ntev ntev ntawm cov khoom siv hluav taws xob muaj zog ntxiv nrog rau qhov sib xws. Cov txheej txheem yog siv cov kua resin sib tov, uas muaj xws li resin, fillers, thiab tshwj xeeb additives, nrog rau textile reinforcing fibers. Tsis txhob thawb cov ntaub ntawv, zoo li ua tiav hauv extrusion, cov txheej txheem pultrusion yuav rub lawv los ntawm cov hlau rhuab sib sau tuag uas siv cov cuab yeej rub tawm tas li.
Cov khoom siv txhawb zog siv yog tas mus li, xws li yob ntawm fiberglass lev thiab doffs ntawm fiberglass roving. Cov ntaub ntawv no yog soaked nyob rau hauv resin sib tov nyob rau hauv ib tug cob da dej thiab ces rub los ntawm lub tuag. Cov cua sov los ntawm qhov tuag pib lub resin lub gelation los yog hardening txheej txheem, uas ua rau ib tug nruj thiab kho profile uas phim cov duab ntawm cov tuag.
Kev tsim cov tshuab pultrusion yuav txawv nyob ntawm seb cov khoom xav tau. Txawm li cas los xij, lub tswv yim ntawm cov txheej txheem pultrusion yog qhia hauv cov schematic hauv qab no.
