Maitiro ekudzivirira epoxy board kubva pakupwanya
Maitiro ekudzivirira epoxy board kubva pakupwanya
Epoxy board ndeye yakakwirira-inoshanda insulating material, iyo inonziwo epoxy glass fiber board, epoxy phenolic laminated glass cloth board uye zvichingodaro. Iyo epoxy board inonyanya kugadzirwa ne: girazi faibha jira rinosungirirwa ne epoxy resin uye rinogadzirwa nekudziya nekumanikidza, saka rine mashandiro akanaka uye akawanda mabhenefiti. Uye inogona kuratidza maitiro ayo mune chero mamiriro ekushisa.
Semuenzaniso, pasi pekushisa kwepakati, inogona kuratidza kushanda kwayo kwemagetsi zvakanaka kwazvo; pasi pemamiriro ekushisa kwepamusoro, inogona kuratidza maitiro ayo emagetsi zvakanaka kwazvo. Naizvozvo, nekuda kwehunhu uhwu, epoxy board yakanyatso kukodzera kune yakakwirira-insulation zvimiro zvikamu mumagetsi nemagetsi minda. Zvese zvinogona kupfupikiswa mumutsara mumwe, kureva, epoxy mapuranga ane yakakwirira mechanical uye dielectric zvivakwa, uye ane yakanakisa kupisa uye hunyoro kuramba. Iyo yepamusoro tembiricha yekudzivirira giredhi ye epoxy board insulation material iF giredhi, kureva kuti, inogona kumira tembiricha yakakwira ye155 degrees, uye inogona kuramba yakagadzikana kushanda kwekushanda pasi pekupisa kwakanyanya kudaro.
Ukobvu hwayo kazhinji huri pakati pe0.5 ne100mm. Iyo inowanzo shandiswa chigadzirwa yakatarwa ndeye 1000mm * 2000mm. Iyo 1200 × 2400 epoxy board insulation material icharemara pakupisa kwepamusoro kwe180 degrees, saka haiwanzo shandiswa nedzimwe simbi, zvikasadaro inogona kukonzera kupisa kwekupisa kwesimbi sheet.
Epoxy resin inowanzosangana nemamiriro ezvinhu anotevera panguva yekushandiswa: EP kukanda, potting, kuumba uye zvimwe zvikamu zvichaputika mushure mekuporesa kana panguva yekuchengetedza, zvichiita kuti zvigadziriswe tsvina. Zvikamu zveEP zvicharatidzawo kutsemuka kana zvave pasi pekushisa kwakadzika kana kuchinjana kupisa uye kutonhora. Iyo yakakura chikamu, inowedzera kuisa, uye zviri nyore kuratidza makatsemuka. Zvinowanzotendwa kuti izvi zvinodaro nekuti kurapa kushushikana uye kushushikana kwekushisa kwakakura kupfuura kusimba kwechinhu. Nokudaro, zvinongodiwa chete kuwedzera simba reEP kuti udzivise kuputika. Asi yakakwirira-simba EP inowanzoita yakaderera kukanganisa kuoma. Kushungurudzika-kubereka zvikamu zvekugadzirisa (zvakadai semagadzirirwo ekugadzirisa, advanced composite materials, etc.) yakagadzirwa nepamusoro-simba EP inowanzoputsika kamwe kamwe panguva yekushandiswa, asi kushungurudzika kwavanowana kwakaderera kudarika simba reEP. Iyo yekutyoka ndeye brittle fracture trace. Inonzi low stress brittle fracture. Iyo EP yakarapwa chigadzirwa ipolymer ine yakakwira dhigirii yekuyambuka-yakabatana uye yakanyanya brittle.
Nezve kuomeswa kwe epoxy resin, nekuti rabha yakaomesesa epoxy resin system inonyanya kuenderana neiyo matrix chimiro uye chidimbu cherubha chimiro panguva yekutyoka, zvakare ine hukama nechimiro chechimiro chezvikamu zviviri uye vhoriyamu chikamu chechikamu. phase. Iko kuomesa kushanduka kunonyanya kutariswa nekuoma kwezvimedu, iyo yunifomu network cheni kureba kwematrix, uye zvakare ine chekuita nekubatana kwemukati uye chimiro chemakemikari yetiweki chain pachayo.
