Sib piv hardness thiab hnav lub neej ntawm lub siab phaj ua hauj lwm nto
Vim li cas thiaj yuav tsum tau tswj lub siab phaj hardness nyob rau hauv ib tug zoo ntau yam?
Tsawg hardness ua rau hnav sai thiab deformation nyob rau hauv kev sib txhuam. High hardness txo cov toughness thiab ua rau chipping thiab brittle puas. Zoo hardness sib npaug hnav tsis kam thiab cuam tshuam toughness. Nws ua kom muaj kev pabcuam ntev yam tsis hnav, tawg lossis deformation. Hardness txuam yog qhov tseem ceeb hauv kev tsim thiab xaiv cov khoom.
Cov txiaj ntsig dab tsi tshwm sim los ntawm kev hnav nrawm ntawm qhov chaw ua haujlwm?
Hnav kom nthuav dav thiab txo qhov muaj peev xwm clamping ntawm phaj thiab tsheb ciav hlau. Lateral txav ntawm rails nce thiab ntsuas yuav nyuaj rau tswj. Cov khib nyiab hlau nrawm nrawm thiab ua rau lub voj voog tsis zoo. Kev hloov pauv tsis tu ncua nce kev ua haujlwm txij nkawm thiab tus nqi. Kev hnav hnyav cuam tshuam tag nrho kev ruaj ntseg ntawm cov qauv khiav.
Vim li cas qee qhov siab - cov phaj hardness tseem ua tsis tau thaum ntxov?
High hardness tsis txaus toughness ua rau tawg thiab chipping nyob rau hauv kev cuam tshuam. Tsis sib xws hardness ua rau cov chaw mos hauv zos thiab hnav thaum ntxov. Kev kho cua sov tsis zoo ua rau kev ntxhov siab sab hauv, deformation thiab tawg. Internal defects nthuav kev puas tsuaj nyob rau hauv siab hardness. Kev pabcuam lub neej nyob ntawm kev sib txuam ntawm hardness, toughness thiab khoom siv tes ua.
Yuav ua li cas xaiv hardness rau txawv kab mob?
Tej yam yooj yim- cov kab ceev tuaj yeem siv cov phaj nrog cov hardness me ntsis thiab tus nqi qis. High-ceev thiab hnyav- cov kab yuav tsum muaj zog dua thiab toughness. Curves thiab keyboards xav tau ntau dua hnav-tiv taus siab- cov phaj tawv. Ncaj thiab ruaj khov seem tso cai rau qis hardness. Xaiv hardness raws li lub qag load, ceev thiab nkhaus vojvoog.
Yuav ua li cas txiav txim siab tsis ua haujlwm tsuas yog ntawm qhov chaw?
Saib xyuas qhov hnav, dent, deformation thiab chipping ntawm qhov chaw ua haujlwm. Tshawb xyuas qhov txawv txav thiab xoob clamping ntawm phaj thiab tsheb ciav hlau. Nquag bolt loosening qhia qhov txawv txav ntawm lub phaj. Cov phaj hauv cov nkhaus thiab cov keyboards hnav sai dua thiab xav tau kev soj ntsuam tseem ceeb. Hloov daim hlau hnav raws sij hawm kom taug qab geometry.
