Cov menyuam abrasion tester yog ib qho tseem ceeb hauv kev ntsuas ntsuas siv los ntsuas qhov hnav tsis kam ntawm roj hmab, yas, thiab cov khoom siv polymer. Nws yog dav siv nyob rau hauv cov ntaub ntawv tshawb fawb, kev soj ntsuam zoo, thiab kev ntsuam xyuas kev ua haujlwm. Nws lub luag haujlwm tseem ceeb yog simulate hnav nyob rau hauv dov lossis kev sib txhuam thiab txiav txim siab cov khoom poob hauv ntim lossis loj, yog li ntsuas kev puas tsuaj.
Ib qho ntawm nws cov yam ntxwv tseem ceeb yog lub siab - cov qauv rigidity. Lub tshuab lub cev feem ntau yog tsim los ntawm siab - zoo steel lossis cam khwb cia cov qauv, muab kev ruaj ntseg zoo thiab kev co kuj. Qhov no ua kom paub tseeb tias ntev - lub sij hawm siab - kev ua haujlwm ceev tsis cuam tshuam rau kev ntsuas qhov tseeb lossis rov ua dua.
Cov cuab yeej tau nruab nrog lub zog ruaj khov thiab cov menyuam kaw lus. Lub cev muaj zog tsav cov menyuam kom tig ntawm qhov nrawm tas mus li, tso cai rau cov qauv kom muaj kev sib cuag nrog cov menyuam nto nyob rau hauv ib qho kev thauj khoom, uas ua rau muaj kev puas tsuaj. Cov menyuam nto yog tshwj xeeb kho kom muaj kev sib txhuam zoo ib yam thiab ua haujlwm ntev.
Lwm qhov tseem ceeb tshaj plaws yog qhov tseeb ntawm kev thauj khoom thiab kev tswj xyuas qhov system. Cov qauv yog ruaj ruaj nyob rau hauv ib tug clamp thiab raug rau ib tug tas li lub siab, tuav ruaj khov kev sib cuag nrog cov menyuam. Lub chaw thau khoom tuaj yeem hloov kho raws li cov qauv ntsuas sib txawv kom tau raws li ntau yam khoom siv thiab txhim kho ntau yam.
Lub tshuab tseem nta cov qauv clamping thiab muab tso rau. Lub fixture yog tsim los kom haum raws li qhov sib txawv ntawm qhov ntau thiab tsawg thiab cov duab, ua kom qhov chaw ruaj khov thoob plaws hauv qhov kev sim thiab tiv thaiv kev txav los yog xoob, yog li txo qhov kev sim ua yuam kev.
Tsis tas li ntawd, cov menyuam abrasion tester feem ntau yog nruab nrog cov plua plav sau thiab kev tiv thaiv kev nyab xeeb. Cov khoom tsim tawm thaum lub sijhawm kuaj tau raug sau tau zoo, thaum lub npog tiv thaiv tiv thaiv cov khib nyiab los ntawm kev tawg, ua kom cov neeg siv kev nyab xeeb thiab tswj xyuas qhov chaw kuaj huv.
Zuag qhia tag nrho, cov menyuam abrasion tester yog tus cwj pwm los ntawm cov qauv nruj, kev tsav tsheb ruaj khov, kev tswj xyuas meej, txhim khu kev qha clamping tsim, thiab kev tiv thaiv kev nyab xeeb. Nws yog ib qho khoom siv tau zoo thiab tseem ceeb rau kev soj ntsuam kev puas tsuaj ntawm cov ntaub ntawv.
