Ungalivimba kanjani ibhodi le-epoxy ukuthi lingaphuli

Ibhodi le-epoxy liyi-high-performance insulating material, ebizwa nangokuthi i-epoxy glass fiber board, i-epoxy phenolic laminated glass cloth board nokunye. Ibhodi le-epoxy lenziwe ngokuyinhloko: indwangu ye-fiber yengilazi ihlanganiswe ne-epoxy resin futhi yenziwa ngokushisa nokucindezela, ngakho inokusebenza okuhle kakhulu kanye nezinzuzo eziningi. Futhi ingabonisa izici zayo kunoma iyiphi indawo yokushisa.

Isibonelo, ngaphansi kwezinga lokushisa eliphakathi, lingabonisa umsebenzi walo wemishini kahle kakhulu; ngaphansi kwemvelo yokushisa ephezulu, ingabonisa izakhiwo zayo zikagesi kahle kakhulu. Ngakho-ke, ngenxa yalezi zici, ibhodi le-epoxy lifaneleka kakhulu ezingxenyeni zesakhiwo se-high-insulation ezindaweni zikagesi neze-elekthronikhi. Konke kungafingqwa ngomusho owodwa, okungukuthi, amabhodi e-epoxy anezakhiwo eziphakeme zemishini kanye ne-dielectric, futhi anokumelana okuhle kakhulu nokushisa nomswakama. Izinga lokushisa eliphakeme lokumelana nezinga lokushisa le-epoxy board insulation material liyibanga lika-F, okungukuthi, lingakwazi ukumelana nezinga lokushisa eliphakeme lama-degree angu-155, futhi lisakwazi ukugcina ukusebenza okuzinzile ngaphansi kwezinga lokushisa eliphezulu kangaka.

Ubukhulu bayo ngokuvamile buphakathi kuka-0.5 no-100mm. Ukucaciswa komkhiqizo okuvame ukusetshenziswa ngu-1000mm*2000mm. I-1200 × 2400 epoxy board insulation material izokhubaza ekushiseni okuphezulu kwama-degrees angu-180, ngakho-ke ngokuvamile ayisetshenziswa nezinye izinsimbi, ngaphandle kwalokho ingabangela ukuguqulwa okushisayo kweshidi lensimbi.

I-epoxy resin ivame ukuhlangana nezimo ezilandelayo ngesikhathi sokusetshenziswa: Ukukhishwa kwe-EP, ukubumba, ukubumba kanye nezinye izingxenye zizoqhekeka ngemva kokuphulukiswa noma ngesikhathi sokugcinwa, okuholela emikhiqizweni yemfucuza. Izingxenye ze-EP zizophinda zibonise imifantu lapho zingaphansi kwezinga lokushisa eliphansi noma ukushisa okushintshisana nokubanda. Ingxenye enkulu, ifaka kakhulu, futhi kulula ukukhombisa imifantu. Ngokuvamile kukholakala ukuthi lokhu kungenxa yokuthi ukucindezeleka okuphulukisayo nokucindezeleka kwezinga lokushisa kukhulu kunamandla wento. Ngakho-ke, kudingekile kuphela ukwandisa amandla e-EP ukugwema imifantu. Kodwa i-EP yamandla aphezulu ijwayele ukuba nokuqina komthelela ophansi. Izingxenye zesakhiwo ezithwala ukucindezeleka (njengama-adhesive esakhiwo, izinto ezihlanganisiwe ezithuthukisiwe, njll.) ezenziwe nge-EP yamandla aphezulu ngokuvamile ziphuka ngokuzumayo ngesikhathi sokusetshenziswa, kodwa ukucindezeleka abakutholayo kuphansi kunamandla e-EP. I-fracture iwukulandelela ukuphuka kwe-brittle. Kubizwa nge-low stress brittle fracture. Umkhiqizo we-EP welashiwe uyi-polymer enezinga eliphezulu lokuxhumanisa futhi i-brittle kakhudlwana.

Mayelana nokuqina kwe-epoxy resin, ngenxa yokuthi isistimu ye-epoxy resin yerabha eqinile ihlobene ngokuyinhloko nesakhiwo se-matrix kanye nesakhiwo senjoloba esiyizinhlayiyana phakathi nenqubo yokuphuka, futhi ihlobene nesimo sokusebenzisana sezigaba ezimbili kanye nengxenye yevolumu yezinhlayiyana. isigaba. Ukushintshashintsha okuqinile kunqunywa ngokuyinhloko ukuqina kwezinhlayiya, ubude beketanga lenethiwekhi efanayo ye-matrix, futhi kuhlobene nokunamathela kobuso kanye nesakhiwo samakhemikhali seketango lenethiwekhi ngokwayo.
