Iimpawu zobugcisa zebhodi ye-resin epoxy

Ngokubanzi, ibakala le ibhodi yokugquma akusiyo ibakala lobuchwephesha, kodwa ibakala lokumelana nobushushu obuphezulu bezinto ezikhuselayo. Iimpawu zokukhusela izinto zokukhusela zihambelana ngokusondeleyo nokushisa. Ukuphakama kweqondo lokushisa, kubi kakhulu iimpawu zokukhusela izinto zokukhusela. Ukuze kuqinisekiswe amandla e-dielectric, i-insulating material nganye inomlinganiselo ofanelekileyo wokushisa ovumelekileyo. Ngaphantsi kobu bushushu, inokusetyenziswa ngokukhuselekileyo ixesha elide. Ukuba idlula lo bushushu, iya kuguga ngokukhawuleza. Ngokwezinga lokumelana nobushushu, izinto zokukhusela zihlulwe zibe yiY, A, E, B, F, H, C kunye namanye amabanga. Ngokomzekelo, ubushushu obuphezulu obuvumelekileyo bokusebenza kweKlasi A yezixhobo zokukhusela i-105 ° C, kwaye ininzi yezixhobo zokukhusela kwii-transformers ezisetyenziswa ngokuqhelekileyo ezisetyenziswayo kunye neenjini ziyingxenye yeKlasi A, njengeebhodi ze-epoxy resin insulating njalo njalo.

Iklasi yobushushu be-Insulation A Iklasi E iklasi B iklasi F iklasi H iklasi

Elona qondo lobushushu livumelekileyo (℃) 105 120 130 155 180

Umda wokunyuka kwamaqondo omoya (K) 60 75 80 100 125

Ubushushu bereferensi yokusebenza (℃) 80 95 100 120 145

Okulandelayo, ndiza kukuthatha ukuba ufunde olunye ulwazi olunxulumeneyo lwebhodi ye-epoxy resin:

Ibhodi ye-epoxy resin yenziwe ngelaphu lefiber yeglasi edityaniswe ne-epoxy resin kwaye ishushu kwaye icinezelwe. Imodeli yi-3240. Inezixhobo eziphezulu zemishini kwiqondo lokushisa eliphakathi kunye neendawo ezizinzileyo zombane kwiqondo lokushisa eliphezulu. Ifanelekile kwiindawo eziphezulu ze-insulation zezakhiwo zoomatshini, izixhobo zombane kunye ne-electronics, ezinezixhobo eziphezulu ze-mechanical kunye ne-dielectric, ukumelana nokushisa okulungileyo kunye nokuxhathisa ukufuma. Iklasi yokumelana nobushushu F (155 degrees).

Kwimathiriyeli ekrwada yebhodi ye-epoxy resin, i-epoxy resin ngokubanzi ibhekisa kwiikhompawundi zepolymer eziphilayo eziqulathe amaqela amabini okanye ngaphezulu epoxy kwimolekyuli. Ngaphandle kwabambalwa, ubunzima babo bemolekyuli abukho phezulu. Isakhiwo se-molecular ye-epoxy resin sibonakaliswe kubukho bamaqela e-epoxy asebenzayo kwikhonkco le-molecular chain, kwaye amaqela e-epoxy anokufumaneka ekupheleni, phakathi okanye kwi-cyclic isakhiwo se-molecular chain. Ngenxa yamaqela e-epoxy asebenzayo kwisakhiwo se-molecular, banokudibaniswa kunye neentlobo ezahlukeneyo ze-agents zokunyanga ukwenza iipolymers ezingenayo kunye ne-infusible kunye nesakhiwo senethiwekhi yeendlela ezintathu.

1. Ubukhulu benkcazo: 0.5～100mm

2. Iinkcukacha eziqhelekileyo: 1000mm * 2000mm

3. Umbala: mthubi

4. Indawo Imvelaphi: Eyasekhaya

5. Iyafudunyezwa kwaye ikhubazeke kubushushu obuphezulu obuyi-180 °C. Ngokuqhelekileyo, ayifudunyezwa kunye nezinye iintsimbi, ezinokubangela ukuguqulwa kwephepha lesinyithi.
