Indlela yokuthintela ibhodi ye-epoxy ukuba ingaphumi

Ibhodi ye-Epoxy yinto ephezulu yokugquma, ekwabizwa ngokuba yi-epoxy glass fiber board, ibhodi yelaphu yeglasi ye-epoxy phenolic elaminated njalo njalo. Ibhodi ye-epoxy yenziwe ngokukodwa: ilaphu lefiber yeglasi lidityaniswe ne-epoxy resin kwaye lenziwe ngokufudumeza kunye noxinzelelo, ngoko linokusebenza okugqwesileyo kunye neenzuzo ezininzi. Kwaye inokubonisa iimpawu zayo kuyo nayiphi na imeko yobushushu.

Umzekelo, phantsi kobushushu obuphakathi, inokubonisa umsebenzi wayo womatshini kakuhle kakhulu; phantsi kwendawo yobushushu obuphezulu, inokubonisa iimpawu zayo zombane kakuhle kakhulu. Ngoko ke, ngenxa yezi mpawu, ibhodi ye-epoxy ifaneleke kakhulu kwiindawo eziphakamileyo ze-insulation zezakhiwo kwiindawo zombane kunye ne-elektroniki. Yonke into inokushwankathelwa kwisivakalisi esinye, oko kukuthi, iibhodi ze-epoxy zineempawu eziphezulu zoomatshini kunye ne-dielectric, kwaye zinobushushu obugqwesileyo kunye nokumelana nokufuma. Umgangatho wokumelana nobushushu obuphezulu be-epoxy board insulation material yi-F grade, oko kukuthi, inokumelana nobushushu obuphezulu be-155 degrees, kwaye isenokugcina ukusebenza okuzinzileyo phantsi kobushushu obunjalo.

Ubukhulu bayo buphakathi kwe-0.5 kunye ne-100mm. Inkcazo yemveliso esetyenziswa ngokuqhelekileyo yi-1000mm * 2000mm. I-1200 × 2400 i-epoxy board insulation material iya kutshintsha kwiqondo lokushisa eliphezulu le-180 degrees, ngoko ke ayisetyenziswanga kunye nezinye iintsimbi, ngaphandle koko kunokubangela ukuguqulwa kwe-thermal sheet sheet.

I-epoxy resin isoloko idibana nezi meko zilandelayo ngexesha lokusetyenziswa: I-EP casting, i-potting, i-molding kunye nezinye iindawo ziya kuqhekeka emva kokunyanga okanye ngexesha lokugcinwa, okubangelwa yimveliso yenkunkuma. Amalungu e-EP nawo aya kubonisa iintanda xa ziphantsi kobushushu obuphantsi okanye ubushushu obutshintshanayo nokubanda. Inxalenye enkulu, ifaka ngakumbi, kwaye kulula ukubonisa ukuqhekeka. Ngokuqhelekileyo kukholelwa ukuba oku kungenxa yokuba uxinzelelo lokunyanga kunye noxinzelelo lweqondo lokushisa lukhulu kunamandla ezinto eziphathekayo. Ngoko ke, kuyimfuneko kuphela ukwandisa amandla e-EP ukuphepha ukuqhekeka. Kodwa i-EP yamandla aphezulu ithande ukuba nefuthe eliphantsi lokuqina. Iingxenye zesakhiwo esinexinzelelo (ezinjengama-adhesives, izinto ezixubileyo eziphambili, njl. njl.) ezenziwe nge-EP yamandla aphezulu ahlala ephuka ngokukhawuleza ngexesha lokusetyenziswa, kodwa uxinzelelo abalufumanayo lungaphantsi kwamandla e-EP. Ukwaphuka kukulandela umkhondo wokwaphuka. Kubizwa ngokuba yi-low stress brittle fracture. Imveliso ye-EP ephilisiwe yipolymer enezinga eliphezulu lokuxhamla kwaye i-brittle ngakumbi.

Ngokuphathelele ukuqina kwe-epoxy resin, ngenxa yokuba inkqubo yerabha eqinile ye-epoxy resin inxulumene ikakhulu nesakhiwo se-matrix kunye nesakhiwo serabha yamasuntswana ngexesha lenkqubo yokwaphuka, ikwanxulumene nemeko yojongano lwezigaba ezibini kunye neqhezu lomthamo weqhekeza. isigaba. Ukuguquguquka kwe-toughening kumiselwe ubukhulu becala ngokuqina kwamasuntswana, ubude bekhonkco lomnatha ofanayo we-matrix, kwaye lunxulumene nokunamatheliswa kobuso kunye nesakhiwo sekhemikhali sekhonkco lomnatha ngokwalo.
