Ukuhlukaniswa kwephepha le-graphite

Ukuhlukaniswa kwephepha le-graphite

Iphepha le-graphite lidlula ochungechungeni lwezinqubo zokwengeza ezifana ne-carbon phosphorus sheet sheet graphite, ukwelashwa kwamakhemikhali, ukukhuphuka kwezinga lokushisa eliphezulu nokugazinga. Inokumelana nokushisa okuphezulu, ukuqhutshwa kokushisa, ukuguquguquka, ukuqina nokusebenza okuhle kakhulu kokuvala. Iphepha le-graphite linezici ezinhle kakhulu. Ngokusho kokusetshenziswa kwayo, ingahlukaniswa ibe uphawuiphepha le-graphite, i-thermal conductive graphite paper kanye ne-conductive graphite paper.
1. Iphepha le-graphite lokuvala uphawu
Isetshenziswe kabanzi emandleni kagesi, embonini yamakhemikhali, izinsimbi, imishini nezinye izimboni. Ingangena esikhundleni sezimpawu zendabuko ezifana nerabha ne-asbestos futhi isetshenziswe njengezigxivizo eziguquguqukayo nezimile zemishini, amapayipi, amaphampu namavalvu.
2. Ukushisa okuqhuba iphepha le-graphite
I-thermal conductive graphite paper ine-conductivity enhle kakhulu yokushisa kanye nokusebenza kokukhipha ukushisa. Isetshenziswa kakhulu kumaselula, amalaptop kanye neminye imikhiqizo kagesi.
3. Iphepha le-graphite eliqhubayo
Isetshenziswa ngokujwayelekile ekukhiqizeni nasekucubunguleni imikhiqizo ehlukahlukene ye-conductive.

Isimiso kanye nokusetshenziswa kwezimboni kwephepha le-graphite

Isimiso sokwenza ukushisa kwephepha le-graphite ukuthi izinga lokushisa eliphezulu nokushisa kuqhuba ukushisa ngokulinganayo ezindaweni ezimbili ebusweni bephepha legraphite. Iphepha le-graphite lingakwazi ukumunca ingxenye yokushisa futhi lisuse ukushisa ngokusebenzisa ukushisa okungaphezulu kwephepha le-graphite, elidlala indima yokukhipha ukushisa. I-conductivity evundlile ye-thermal yephepha legraphite ngokuvamile iphakathi kwe-w / mk kanye ne-thermal conductivity eqondile iphakathi kuka-10-20w / mK, I-conductivity eshisayo ilingana ngokuqondile nentengo yephepha legraphite.

Uma kuqhathaniswa nezinto zensimbi zendabuko, ukushintshwa okushisayo kwephepha legraphite izikhathi ezi-3 ~ 5 kunethusi ne-aluminium.Iphepha legraphite elincanyana kakhulungokuvamile isetshenziselwa izicelo zokuqhuba ukushisa kwezinto zikagesi. I-Ultra thin graphite inokumelana nokushisa okuphansi, ama-40% aphansi kune-aluminium kanye nama-20% aphansi kunethusi. Iphepha le-graphite lingasikwa libe yizimo ezihlukahlukene, futhi iphepha le-graphite le-heat conduction lingasetshenziselwa ukuqeda ukushisa kwemishini kagesi.
