Yam dab tsi feem ntau txiav txim siab cov yam ntxwv ntawm kev sib tsoo log?
May 19, 2024| Cov yam ntxwv ntawm kev sib tsoo log yog tsuas yog txiav txim los ntawm tsib yam: abrasive, particle loj, binder, hardness thiab lub koom haum. 12
Abrasive: Cov khoom siv tseem ceeb ntawm kev sib tsoo lub log, lub luag haujlwm rau kev txiav ua haujlwm, yuav tsum muaj hardness siab, zoo kub tsis kam thiab qee qhov toughness. Feem ntau cov abrasives muaj xws li corundum thiab silicon carbide, uas tsim nyog rau kev sib tsoo sib txawv.
Particle loj: hais txog qhov loj ntawm cov khoom abrasive, uas cuam tshuam rau qhov roughness thiab productivity ntawm machined nto. Coarser abrasive hais yog siv rau kev sib tsoo ntxhib, thiab finer abrasive hais yog siv rau kev sib tsoo zoo.
Binder: Cov khoom siv los khi cov abrasive, uas cuam tshuam rau lub zog, cuam tshuam tsis kam, kub tsis kam thiab corrosion kuj ntawm kev sib tsoo log. Common binders muaj xws li ceramic binders, resin binders, roj hmab binders thiab hlau binders.
Hardness: Qhov yooj yim uas cov khoom abrasive nyob rau saum npoo ntawm lub log sib tsoo poob rau hauv qhov kev txiav txim ntawm kev sib tsoo quab yuam. Qhov softer lub hardness, qhov yooj yim dua nws yog rau abrasive hais kom poob, thaum lub hardness harder, qhov nyuaj nws yog rau abrasive hais kom poob.
Lub koom haum: yog hais txog kev sib raug zoo ntawm qhov ntim ntawm cov khoom siv abrasive, binders thiab pores, uas cuam tshuam rau kev sib tsoo thiab kev sib tsoo ntawm kev sib tsoo. Cov txheej txheem ntawm cov ntaub so ntswg yog muab faib ua nruj, nruab nrab, thiab xoob, uas tau muab faib ua ntau theem.
