Iav Fiber Mat
(1) Muab cov tawv ntoo pov tseg. Iav strands (tej zaum kuj rov qab) yog muab txiav rau hauv 50 hli qhov ntev, tiam sis tusyees muab tso rau hauv ib txoj siv mesh, ua raws li daim ntawv thov ntawm ib phau ntawv emulsion los yog dusting nrog ib tus phom hmoov. Tom qab cua sov thiab kho kom zoo, lawv yuav raug khi rau hauv cov tawv ntoo. Cov tev nti tawm ntawm cov ntaub pua plag yog siv tes ua lag luam, nruam cov laug, thiab tuag taus thiab SMC cov txheej txheem. Qhov uas yuav tsum tau ua rau cov tawb tawv nqaij yuav tsum yog raws li nram qab no: 1 Lub cheeb tsam hauv dav dav yog ntawm kev ua tsis zoo; 2 Cov tawb strands yog sib npaug faib rau hauv lub lev, tsis muaj qhov loj yog tsim, thiab tus binder yog sib npaug; 3 muaj ib lub cev qhuav dej muaj zog; 4 zoo heev Reviltration thiab permeability.
(2) Nruam cov pob zeb tawg Cov nyom iav tau tsim thaum cov txheej txheem los yog cov hlua nrawm los ntawm cov thawj cov ntawv me me uas tau muab tso rau hauv ib daim duab 8 uas muaj qhov sib txuas ntxiv mus rau hauv cov ntaub qhwv lub hnab. Cov fiber ntau hauv daim duab fiberglass nruam tas li, yog li nws cov khoom siv rau hauv cov khoom siv puas tsawg dua thiab cov lev zoo dua. Feem ntau siv rau hauv txoj kev nyuaj siab, RTM txoj kev, lub hnab ntim siab thiab iav lev siv zog thermal yas (GMT) thiab lwm cov kev ua haujlwm.
(3) Cov Ntoo Liab Cov iav fiber reinforced yas khoom feem ntau yuav tsum tau tsim ib txheej dej nplua nuj, uas feem ntau tau los ntawm alkali iav saum npoo pas. Qhov hom ntawm no yog ua los ntawm alkali iav (C), yog li nws muab cov tshuaj tiv thaiv thiab tshwj xeeb tshaj yog acid tsis kam mus rau iav hlau. Nyob rau tib lub sij hawm, vim hais tias tus ntsoov yog nyias thiab lub cheeb ntawm iav fiber ntau yog zoo, nws muaj peev xwm nqus ntau daim duab los ua tus nplua nuj resin txheej. Nyob rau hauv cov iav fiber reinforced khoom (xws li daim ntaub gingham), ua si ntawm qhov kev hloov kho deg.
