Yuav ua li cas thiaj ntxuav tau cov pwm graphite?

Feem ntau, thaum cov txheej txheem molding tiav lawm, cov av lossis cov khoom seem (nrog rau qee yamtshuaj lom neeg muaj pes tsawg leegthiabcov khoom siv lub cev) feem ntau yog tso rau ntawmpwm graphite. Rau ntau hom seem sib txawv, qhov yuav tsum tau ntxuav zaum kawg yog txawv. Cov resins xws li polyvinyl chloride yuav tsim cov roj hydrogen chloride, uas yuav ua rau ntau hom graphite pwm hlau xeb. Lwm cov seem raug cais tawm ntawm cov tshuaj tua hluav taws thiab cov tshuaj antioxidants, uas tuaj yeem ua rau xeb rau hlau. Kuj tseem muaj qee cov xim pigment uas tuaj yeem xeb hlau, thiab cov xeb nyuaj rau tshem tawm. Txawm tias cov dej kaw dav dav, yog tias nws tso rau ntawm qhov chaw ntawm cov pwm graphite tsis kho ntev dhau, nws tseem yuav ua rau puas tsuaj rau cov pwm graphite.

Yog li ntawd, cov pwm graphite yuav tsum tau ntxuav raws li qhov tsim nyog raws li lub voj voog tsim khoom. Txhua zaus uas cov pwm graphite raug coj tawm ntawm lub tshuab nias, qhov hws ntawm cov pwm graphite yuav tsum tau qhib kom tshem tawm tag nrho cov av oxidized thiab xeb ntawm cov chaw tsis tseem ceeb ntawm cov pwm graphite thiab cov qauv kom tiv thaiv nws kom tsis txhob maj mam xeb qhov chaw thiab ntug ntawm cov hlau. Hauv ntau qhov xwm txheej, txawm tias tom qab ntxuav, qee cov pwm graphite tsis muaj txheej lossis xeb yuav sai sai qhia cov cim ntawm xeb dua. Yog li ntawd, txawm tias nws siv sijhawm ntev los ntxuav cov pwm graphite tsis muaj kev tiv thaiv, qhov tsos ntawm xeb tsis tuaj yeem zam tau tag nrho.

Feem ntau, thaum siv cov yas tawv, cov hlaws iav, cov plhaub txiv ntoo walnut thiab cov pellets txhuas ua cov khoom siv abrasives rau kev sib tsoo siab thiab ntxuav qhov chaw ntawm cov pwm graphite, yog tias cov khoom siv abrasives no siv ntau zaus lossis tsis raug, txoj kev sib tsoo no kuj yuav ua rau muaj teeb meem. Porosity tshwm sim rau ntawm qhov chaw ntawm cov pwm graphite thiab cov seem yooj yim lo rau nws, ua rau muaj ntau cov seem thiab hnav, uas yuav ua rau tawg ua ntej lossis flashing ntawm cov pwm graphite, uas tsis zoo rau kev ntxuav cov pwm graphite.

Tam sim no, ntau lub pwm graphite muaj cov kav dej "tus kheej ntxuav", uas muaj qhov ci ntsa iab. Tom qab ntxuav thiab txhuam lub qhov cua kom ua tiav qib polishing ntawm SPI # A3, tej zaum tom qab milling lossis sib tsoo, cov seem raug tso tawm mus rau thaj chaw pov tseg ntawm cov yeeb nkab cua kom tiv thaiv cov seem los ntawm kev lo rau ntawm qhov chaw ntawm lub rooj dov ntxhib. Txawm li cas los xij, yog tias tus neeg teb xov tooj xaiv cov ntaub ntxuav ntxhib, daim ntaub emery, ntawv xuab zeb, pob zeb sib tsoo, lossis txhuam nrog nylon bristles, tooj dag lossis hlau los sib tsoo cov pwm graphite, nws yuav ua rau "ntxuav" ntau dhau ntawm cov pwm graphite. .

Yog li ntawd, tom qab nrhiav cov khoom siv ntxuav uas haum rau cov pwm graphite 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 cov pwm graphite tuaj yeem txo qis.
