Yuav ua li cas ntxuav cov pwm graphite?

Feem ntau, thaum cov txheej txheem molding tiav lawm, cov av lossis cov khoom seem (nrog rau qee yam tshuaj lom neeg thiab cov khoom siv lub cev) feem ntau raug tso tseg rau ntawmpwm graphite. Rau ntau hom seem sib txawv, qhov yuav tsum tau ntxuav kuj txawv. Cov resins xws li polyvinyl chloride tsim cov roj hydrogen chloride, uas tom qab ntawd corrodes ntau hom graphite tuag hlau. Lwm cov seem raug cais tawm ntawm cov nplaim taws retardants thiab antioxidants thiab tuaj yeem ua rau xeb rau hlau. Qee cov xim pigment yuav xeb cov hlau, thiab cov xeb nyuaj rau tshem tawm. Txawm tias cov dej kaw dav dav, yog tias muab tso rau ntawm qhov chaw ntawm cov pwm graphite tsis kho rau lub sijhawm ntev, nws tseem yuav ua rau puas tsuaj raupwm graphite.
Yog li ntawd, cov pwm graphite yuav tsum tau ntxuav raws li lub voj voog tsim khoom uas tau teeb tsa. Tom qab cov pwm graphite raug coj tawm ntawm lub tshuab txhua zaus, ua ntej qhib lub qhov cua ntawm cov pwm graphite kom tshem tawm tag nrho cov av oxidation thiab xeb hauv cov cheeb tsam tsis tseem ceeb ntawm cov pwm graphite thiab cov qauv, kom tiv thaiv nws kom tsis txhob maj mam xeb cov hlau nto thiab ntug. Hauv ntau qhov xwm txheej, txawm tias tom qab ntxuav, qee cov pwm graphite tsis muaj txheej lossis xeb yuav sai sai pom xeb dua. Yog li ntawd, txawm tias nws siv sijhawm ntev los ntxuav cov pwm graphite tsis muaj kev tiv thaiv, qhov tsos xeb tsis tuaj yeem zam tau tag nrho.
Feem ntau, thaum cov yas tawv, cov hlaws iav, cov plhaub txiv ntoo walnut thiab cov khoom txhuas raug siv los ua cov khoom siv abrasives rausiab siabKev sib tsoo thiab ntxuav qhov chaw ntawm graphite pwm, yog tias cov khoom siv abrasives no siv ntau zaus lossis tsis raug, txoj kev sib tsoo no kuj tseem yuav ua rau cov qhov hws ntawm qhov chaw ntawm graphite pwm thiab yooj yim rau cov khoom seem lo rau nws, ua rau muaj ntau cov khoom seem thiab hnav, Nws yuav ua rau tawg ua ntej lossis burr ntawm graphite pwm, uas tsis zoo rau kev ntxuav graphite pwm.
Tam sim no, ntau lub pwm graphite muaj cov kab qhov cua "tus kheej ntxuav", uas muaj qhov ci ntsa iab. Tom qab ntxuav thiab txhuam lub qhov cua kom txog qib polishing ntawm spi # a3, lossis milling lossis sib tsoo, tso cov seem mus rau thaj chaw pov tseg ntawm lub yeeb nkab qhov cua kom tiv thaiv cov seem los ntawm kev lo rau ntawm qhov chaw ntawm lub hauv paus zeb roughing. Txawm li cas los xij, yog tias tus neeg teb xov tooj xaiv cov gasket flushing coarse-grained, daim ntaub emery, ntawv xuab zeb, pob zeb sib tsoo lossis txhuam nrog nylon bristle, tooj dag lossis hlau los sib tsoo lub pwm graphite manually, nws yuav ua rau "ntxuav" ntau dhau ntawm lub pwm graphite.
Yog li ntawd, los ntawm kev tshawb nrhiav cov khoom siv ntxuav uas haum rau graphite pwm thiab cov txheej txheem ua thiab xa mus rau cov txheej txheem ntxuav thiab cov voj voog ntxuav uas tau sau tseg hauv cov ntaub ntawv khaws cia, ntau dua 50% ntawm lub sijhawm kho tuaj yeem txuag tau thiab kev hnav ntawm graphite pwm tuaj yeem txo qis.
