Kev Ntsuas Hardness ntawm HS Shore rau Carbon Brush Block

Cov txhuam carbon uas teev hauv qab no yog cov qauv xa los ntawm peb cov neeg siv khoom, uas xav tau kev kuaj Shore HS hardness.

Peb siv lub Shore hardness tester uas qhia saum toj no los ua qhov kev sim hardness ntawm cov neeg siv khoom cov qauv.

Qhov kev sim Shore hardness rau cov carbon blocks no yog qhov kev sim dynamic rebound hardness. Lub pob zeb diamond indenter nrog qhov hnyav ruaj khov poob dawb los ntawm qhov siab tus qauv los cuam tshuam rau qhov chaw ntawm cov carbon block. Tus nqi Shore hardness (HS/HSD) raug hloov pauv raws li qhov siab elastic rebound ntawm cov khoom siv. Qhov nyeem ntawv hardness qhia ncaj qha rau qhov ceev, graphite orientation, pore structure thiab qhov tsis kam ntawm qhov elastic deformation ntawm cov carbon block.

Cov Qauv Yuav Tsum Tau Ua Rau Kev Ntsuas

Cov pa roj carbon yuav tsum muaj qhov tuab tsawg kawg yog 5 hli. Cov ntawv nyias nyias, cov khoom me me thiab cov khoom carbon phab ntsa nyias tsis tsim nyog rau kev kuaj. Qhov tuab tsis txaus yuav ua rau muaj kev co thiab kev hloov pauv ntawm cov qauv, ua rau muaj qhov nyeem tau qhov nyuaj siab tsis zoo. Qhov chaw kuaj yuav tsum tiaj tus, tsis muaj kab nrib pleb, plua plav thiab tawg, nrog rau qhov roughness ntawm qhov chaw Ra ≤ 3.2 μm. Cov chaw ntxhib thiab qhov dej nqus cov zog cuam tshuam, uas ua rau qhov ntsuas qhov nyuaj qis.

Cov txiaj ntsig ntawm Qhov Shore Hardness Tester no

Lub tshuab ntsuas Shore hardness portable no yog lub teeb yuag thiab yooj yim siv., tsis tas yuav muaj lub rooj sib tw kuaj sib phim. Cov pa roj carbon loj, cov cib carbon thiab cov khoom seem uas tsim tau tuaj yeem kuaj ncaj qha rau ntawm qhov chaw yam tsis tas txiav cov qauv. Nws yog qhov tsim nyog rau kev tshuaj xyuas cov kab ntau lawm thiab kev lees txais cov khoom tiav hauv qhov chaw.

Kev Ntsuas Tsis Ua Phem Zoo

Cov nyeem tau yooj yim hauv ob peb feeb xwb, zoo tagnrho rau kev sim ceev ceev. Qhov kev cuam tshuam tsis tob heev yam tsis ua rau puas tsuaj rau qhov chaw ua haujlwm ntawm cov khoom ua haujlwm, tsis muaj kev cuam tshuam tsis zoo rau kev ua haujlwm tom qab thiab kev sib dhos tom qab sim.

Cov kev ceev faj

Yuav tsum nco ntsoov tias lub tshuab ntsuas qhov nyuaj no muaj cov kev txwv piv rau qhov kev ntsuas qhov nyuaj zoo li qub hauv qhov tseeb: cov ntaub ntawv xeem tau tawg ua qhov nruab nrab. Cov txiaj ntsig xeem raug cuam tshuam los ntawm qhov ntsug ntawm lub cuab yeej, qhov tiav ntawm cov pa roj carbon, qhov hws sab hauv thiab kev taw qhia ntawm cov noob graphite. Cov nqi xeem ntau ntawm tib qho qauv hloov pauv ntau heev. Cov ntaub ntawv nyuaj tsuas yog sib piv rau cov pa roj carbon nrog cov qauv elastic modulus thiab cov qauv pore zoo sib xws. Cov nqi xeem ntawm cov pa roj carbon nrog cov qauv sib txawv lossis cov degree graphitization tsis tuaj yeem xa mus ncaj qha.

Thaum lub sijhawm kuaj, cov khoom me me raug teeb tsa raws li kev taw qhia thaum lub sijhawm tsim cov pa roj carbon, ua rau muaj cov nqi rov qab sib txawv sib luag thiab sib npaug rau qhov kev taw qhia tsim. Yuav tsum tau txais kev taw qhia kuaj ruaj khov thaum lub sijhawm kuaj; txwv tsis pub, cov ntaub ntawv kuaj yuav tsis raug.
