Entwodiksyon nan aplikasyon an nan materyèl friksyon
Materyèl asbès yo lajman itilize kòm materyèl friksyon pou kousinen fren otomobil. Malgre ke chay -kapasite pote yo pa menm jan ak sa yo ki nan materyèl metaliji poud, li gen yon koyefisyan friksyon segondè ak fèmen koyefisyan friksyon dinamik ak estatik, ki ka fè frenaj ki estab, ki ba bri, ak pri ki ba.
Li ka travay nòmalman anba chaj segondè ak tanperati ki wo, epi li se espesyalman li te ye pou koyefisyan friksyon ki estab li yo ak bon rezistans mete. Se poutèt sa, li itilize kòm kousinen fren pou aterisaj avyon, plak friksyon boul vis pou chay lou, ak plak anbreyaj pou mekanis elektrik.
Nan machin transpò tankou otomobil, bato, tren, gwo ak mwayen -machin konstriksyon tankou bouteur, asansè min, pneu ak traktè, machin agrikòl, ak machin endistriyèl limyè, espesifikasyon divès kalite ak kalite disk friksyon metaliji poud. , kousinen fren, elatriye Anplis de sa nan ekselan fini anbreyaj ak frenaj, li kapab tou redwi konsomasyon enèji ak amelyore presizyon transmisyon. Ak devlopman nan teknoloji modèn, demann pou materyèl friksyon segondè -pèfòmans vin pi ijan.
The carbon-carbon composite material that appeared in the late 1970s is a promising friction material. It has stable high-temperature friction performance, long life, and light weight. It has been successfully used in the braking devices of Concorde and Boeing aircraft. It's just that the price is expensive, which affects the wide range of applications. Graphite-based friction material with good performance under medium load, low temperature and wet friction conditions is also a new type of material with great development prospects. It has almost all the advantages of asbestos and powder metallurgy materials at present, and the price is cheap, and it is an ideal friction material.
