Yiziphi izicaciso zobuchwepheshe zokumbozwa kwangaphandle kwepayipi le-epoxy glass fiber?
Yiziphi izicaciso zobuchwepheshe zokumbozwa kwangaphandle kwepayipi le-epoxy glass fiber?
1) Isilinganiso samandla ku-modulus siphezulu. Amandla athile kanye nemodulus ethize kubhekisela kumandla wento esetshenziswayo kanye nesilinganiso semodulus ukuya kokuminyana. Ukuphakama kwamandla athile, isisindo sengxenye sincane. Uma iphezulu imodulus ethize, kuyanda ukuqina kwengxenye. Ngakho-ke, isidingo sokusebenza ngesivinini esiphezulu sezingxenye zesakhiwo noma ukunciphisa isisindo sokuthutha sibaluleke kakhulu.
I-2) I-interface phakathi kwe-fiber kanye ne-matrix ku-fiber reinforced composite material ingavimbela ngokuphumelelayo ukusakazwa kwemifantu yokukhathala, futhi umthwalo wangaphandle uthwalwa yi-fiber eqinisiwe. Umkhawulo wamandla wokukhathala wezinto eziningi zensimbi ungama-30% ~ 50% wamandla ayo aqinile, kuyilapho umkhawulo wamandla wokukhathala wezinto eziyinhlanganisela ungama-60% ~ 80%
I-3) Ukwengeza inani elincane le-carbon fiber eqoshiwe ku-thermoplastics kungathuthukisa kakhulu ukumelana kwayo nokugqoka, futhi isikhathi sayo sokwengeza singaba izikhathi eziningana. Isibonelo, i-carbon fibre eqiniswe i-PVC yizikhathi ezingu-3.8 eyakhe, i-PTFE iyizikhathi ezi-3 eyakhe, i-polypropylene iyizikhathi ezingu-2.5 zayo, i-polyamide iyizikhathi ezingu-1.2 eyakhe, kanti i-polyester iyizikhathi ezi-2 eyakhe. Izikhathi. Ngokusebenzisa into efanelekile eyinhlanganisela yepulasitiki nensimbi, ingasetshenziswa njengento engagugi, njengempahla yokuthwala. Impahla eyinhlanganisela yezendlalelo ezintathu ene-polytetrafluoroethylene (noma i-polyoxymethylene) njengongqimba olungaphezulu kanye ne-bronze enezimbobo kanye nepuleti lensimbi njengoba ungqimba lwangaphakathi lungenziwa lube izinto ezinhle kakhulu zamabheringi okuslayida.
I-4) Ukuzinza kwamakhemikhali okuhle kakhulu. Amapulasitiki e-phenolic aqiniswe nge-fiber angasetshenziswa emithonjeni ye-acidic equkethe ama-ion e-chloride isikhathi eside. Kusetshenziswa amapulasitiki aqiniswe nge-fiber fiber, amapayipi amakhemikhali, amaphampu, ama-valve neziqukathi ezimelana nama-asidi aqinile, usawoti, ama-ester kanye nezinyibilikisi ezithile zingenziwa. Uma i-alkali-resistant fiber ixutshwe nepulasitiki, ingasetshenziswa endaweni eqinile ye-alkali. Imicu engamelana ne-alkali ingasetshenziswa esikhundleni sezinto eziyinhlanganisela zensimbi nosimende.
I-5) Ukumelana nokushisa okuphezulu kwe-ablation. Ngaphandle kwephuzu elincibilikayo eliphansi (900°C) kanye nephuzu elincibilikayo eliphansi (700°C) eliyinhlanganisela yezinto, ngokuvamile liqiniswa ngemicu yensimbi. Isibonelo, uma i-carbon fibre noma i-boron fiber isetshenziswa njengento eqinisayo, amandla kanye ne-modulus ku-400° C. ingagcinwa ngokuyisisekelo emazingeni okushisa asekamelweni. I-carbon fiber efanayo eqinisiwe i-nickel ayigcini nje ukunciphisa ukuminyana, kodwa futhi inomsebenzi wokushisa ophezulu. I-FRP ine-conductivity ephansi kakhulu ye-thermal kanye nokusebenza ngokushesha kwezinga lokushisa eliphezulu, ngakho-ke ingasetshenziswa njengento ephikisana nokukhipha umoya.
6) Ubuchwepheshe obuhle nokuhlela. Ngokulungisa ukuma, ukwakheka kanye nokuqukethwe kwezinto eziqinisayo, amandla kanye nokuqina kwezingxenye kungahlangatshezwana nazo, futhi izinto zokwakha kanye nezingxenye zingakhiwa ngesikhathi esisodwa, ngaleyo ndlela kuncishiswe inani lezingxenye, izinsimbi namajoyinti, futhi kuthuthukiswe kakhulu. amandla ezingxenye. Ukusetshenziswa kwezinto.
