Ukuhlelwa kwephepha legraphite

Ukuhlelwa kwephepha legraphite

Iphepha legraphite lidlula kuluhlu lweenkqubo zokongezwa ezifana nekhabhoni ephezulu ye-phosphorus sheet graphite, unyango lwekhemikhali, ukunyuswa kobushushu obuphezulu kunye nokuqhotswa. Inokumelana nobushushu obuphezulu, ukuqhuba ubushushu, ukuguquguquka, ukomelela kunye nokusebenza okugqwesileyo kokutywinwa. Iphepha legraphite lineempawu ezibalaseleyo. Ngokutsho kwesicelo sayo, inokwahlulwa ngokutywinwaiphepha legraphite, i-thermal conductive graphite paper kunye ne-conductive graphite paper.
1. Iphepha legraphite lokutywinwa
Isetyenziswe ngokubanzi kumandla ombane, ishishini lemichiza, isixhobo, oomatshini kunye namanye amashishini. Inokutshintsha izitywina zemveli ezifana nerabha kunye neasbestos kwaye zisetyenziswe njengezitywina eziguqukayo nezizinzileyo koomatshini, imibhobho, iimpompo kunye neevalvu.
2. Ubushushu obuqhuba iphepha legraphite
Iphepha legraphite le-Thermal conductive line-conductivity egqwesileyo ye-thermal kunye nokusebenza kokutshatyalaliswa kobushushu. Isetyenziswa ikakhulu kwi mobile phones, laptops kunye nezinye iimveliso zombane.
3. Iphepha legraphite eliqhubayo
Isetyenziswa ngokuqhelekileyo kwimveliso kunye nokusetyenzwa kweemveliso ezahlukeneyo zokuqhuba.

Umgaqo-siseko kunye nokusetyenziswa kwemizi-mveliso yephepha legraphite

Umgaqo wokuqhuba ubushushu wephepha legraphite kukuba ubushushu obuphezulu kunye nobushushu buqhuba ubushushu ngokulinganayo kumacala omabini kumphezulu wephepha legraphite. Iphepha legraphite liyakwazi ukufunxa inxalenye yobushushu kwaye lisuse ubushushu ngokuqhuba ubushushu kumphezulu wephepha legraphite, elidlala indima yokutshatyalaliswa kobushushu. I-horizontal conductivity ye-thermal yephepha legraphite iphakathi kwe-w / mk kunye ne-thermal conductivity ephakathi kwe-10-20w / mK, I-thermal conductivity ihambelana ngokuthe ngqo kwixabiso lephepha legraphite.

Xa kuthelekiswa nezinto zentsimbi zemveli, i-thermal conductivity yephepha legraphite yi-3 ~ 5 amaxesha obhedu kunye ne-aluminium.Iphepha elicekethekileyo legraphitengokuqhelekileyo isetyenziselwa ukuqhuba ubushushu izicelo zezixhobo zombane. Igraphite ebhityileyo kakhulu inokumelana ne-thermal ephantsi, i-40% ingaphantsi kune-aluminiyam kunye ne-20% ngaphantsi kunobhedu. Iphepha legraphite linokusikwa libe ziimo ezahlukeneyo, kwaye iphepha legraphite lokuqhuba ubushushu lingasetyenziselwa ukuphelisa ubushushu bezixhobo zombane.
