Graphite screws muaj ntau yam kev siv thiab feem ntau yog siv nyob rau hauv kev lag luam teb uas yuav tsum tau kub, corrosion kuj thiab tsis muaj kev sib txhuam. cov
Graphite screws yog dav siv nyob rau hauv aerospace, petrochemical, nuclear fais fab nroj tsuag thiab precision instruments. Vim lawv qhov kub thiab txias tsis kam, graphite screws tuaj yeem nyob ruaj khov nyob rau hauv qhov kub thiab txias ib puag ncig mus txog phav phav degrees Celsius, tiv thaiv kom tsis txhob xoob lossis tawg teeb meem tshwm sim los ntawm cov thermal expansion coefficients tsis sib haum. Tsis tas li ntawd, graphite screws muaj qhov zoo corrosion kuj thiab nws tus kheej lubricating zog, thiab yuav siv tau nyob rau hauv cov tshuaj corrosive media los yog tej lub sij hawm uas yuav tsum tau nquag disassembly, ncua lub neej kev pab cuam ntawm cov khoom thiab txo nqi txij nkawm.
Nyob rau hauv aerospace teb, graphite screws yog siv los txuas cov ntsiab lus tseem ceeb kom ntseeg tau tias kev ua haujlwm ruaj khov ntawm cov kab ke hauv qhov chaw huab cua. Nws zoo heev thermal conductivity thiab mechanical zog ua rau nws yog ib qho kev xaiv zoo tshaj plaws rau kev tsim thermal conductive structural seem ntawm spacecraft thiab roj teeb rwb thaiv tsev cov ntaub ntawv. Hauv kev lag luam tsheb, graphite screws yog siv rau kev sib txuas ntawm cov cav, chassis thiab lub cev, thiab ua lub luag haujlwm tseem ceeb hauv cov tshuab hluav taws xob. Hauv kev lag luam hluav taws xob, graphite screws yog siv los sib sau ua ke thiab txuas cov khoom siv hluav taws xob xws li Circuit Court boards, resistors thiab capacitors, coj kom zoo dua ntawm lawv cov conductivity zoo thiab kub tsis kam.
