Graphite Packing, raws li cov khoom lag luam tseem ceeb, tau siv dav hauv kev ua lag luam luam tawm rau kev sib hloov duab, cov reciproting applications. Nws txoj haujlwm ua haujlwm yog nyob ntawm cov khoom siv lub cev thiab tshuaj lom neeg ntawm graphite. Los ntawm cov qauv tsim qauv thiab kev yoog raws kev ua haujlwm ua haujlwm, nws ua tiav qhov sib npaug ntawm kev sib npaug thiab hnav tsis kam. Kab lus no yuav tham txog cov khoom siv ntawm graphite graphite packing, nws cov tshuab sib khi, yam cuam tshuam rau kev ua haujlwm, thiab cov ntaub ntawv raug cai raug.
Cov Khoom Siv Khoom thiab Cov Haujlwm Yooj Yim ntawm Graphite Packing
Cov khoom siv tseem ceeb ntawm graphite packing yog feem ntau nthuav graphite los yog yoog raws graphite. Nws yog tsim los ntawm chemically kho ntuj ci graphite (xws li kev sib txuas lus) thiab tom qab ntawd nthuav nws ntawm qhov kub. Cov txheej txheem no tsis muaj zog ntawm cov khaubncaws sab nraud ntawm cov khaubncaws sab nraud ntawm cov khaubncaws sab nraud povtseg, kev tsim cov cua nab kuab uas muaj xoob xoob nrog cov qauv xoob thiab ntxeem tau. Cov cua nab no tau nias los yog pwm hauv cov nplhaib ntim lossis hlua nrog qee qhov kev hloov pauv thiab zaws.
Cov Ntsiab Lus Tseem Ceeb Qhia Cia:
1. Tus kheej - lubrication: graphite siv lead ua yooj yim, feem ntau 0.05- Txo qhov chaw pov tseg yam tsis muaj kev xav tau ntau lubricants.
2. High {- Cov kab mob ntshiab tuaj yeem tiv thaiv kev ua haujlwm tas mus li 450℃nrog kev kho mob tshwj xeeb txawm tias muaj kev kub ntxhov.
3. Tshuaj lom neeg Inertness: Graphite yog inert rau feem ntau cov acids, hauv paus, thiab nitric acid), ua rau nws haum rau kev ua haujlwm corrosive.
4. Kev zaws: los ntawm kev tswj cov tshuab hluav taws xob (feem ntau 20% -30%), tus muab tub lim tawm tuaj yeem ua rau muaj kev sib tw thiab cov kev tsim kho kev sib tw pib sib zog.
