Cov Ntawv Thov Phaj Hlau Uas Tiv Thaiv Kev Sib Txhuam

● Cov phaj AR235 yog tsim los rau kev siv hnav nruab nrab uas nws muaj kev tiv thaiv kev hnav zoo dua li cov hlau carbon.
● Cov AR400 yog cov hlau phaj zoo tshaj plaws uas tsis yooj yim puas thiab tau kho cua sov thiab ua kom tawv. Zoo dua qub rau kev tsim thiab kev sib txuas.
● AR450 yog ib daim phaj uas tiv taus kev sib txhuam uas siv rau ntau yam kev siv uas xav tau lub zog ntau dua li AR400.
● Cov phaj AR500 yog tsim rau kev siv hauv kev khawb av, kev cog ntoo thiab kev tsim kho.
● AR600 siv rau hauv cov chaw uas muaj kev hnav ntau xws li kev tshem tawm cov pob zeb sib xyaw, kev khawb av, thiab kev tsim cov thoob thiab cov khoom hnav.
Cov phaj hlau uas tiv taus kev sib txhuam (AR) feem ntau yog ua nyob rau hauv cov xwm txheej raws li dov. Cov hom / qib ntawm cov khoom phaj hlau no tau tsim tshwj xeeb rau lub neej ntev hauv cov xwm txheej hnyav. Cov khoom AR yog qhov tsim nyog rau ntau yam kev siv hauv thaj chaw xws li kev khawb av / kev khawb av, kev xa khoom, kev tuav cov khoom siv thiab kev tsim kho, thiab kev tsiv av. Cov neeg tsim qauv thiab cov neeg ua haujlwm hauv cov nroj tsuag xaiv cov phaj hlau AR thaum siv zog los txuas lub neej kev pabcuam ntawm cov khoom tseem ceeb, thiab txo qhov hnyav ntawm txhua chav tsev uas muab tso rau hauv kev pabcuam. Cov txiaj ntsig ntawm kev siv cov phaj hlau uas tiv taus kev hnav hauv cov ntawv thov uas muaj kev cuam tshuam thiab / lossis kev sib cuag nrog cov khoom siv abrasive yog qhov loj heev.

Cov hlau alloy uas tiv taus kev sib txhuam feem ntau muaj kev tiv taus zoo rau kev swb thiab kev sib txhuam. Cov pa roj carbon ntau hauv cov hlau alloy ua rau cov hlau tawv thiab tawv dua, ua rau nws yog cov khoom siv zoo tagnrho rau cov ntawv thov uas xav tau kev cuam tshuam siab lossis kev sib txhuam siab. Nws muaj peev xwm tau txais kev tawv siab nrog cov hlau carbon siab, thiab cov hlau yuav muaj kev tiv taus zoo rau kev nkag mus. Txawm li cas los xij, tus nqi hnav yuav nrawm dua piv rau cov hlau alloy kho cua sov vim tias cov hlau carbon siab yog brittle, yog li cov khoom me me tuaj yeem yooj yim dua los ntawm qhov chaw. Yog li ntawd, cov hlau carbon siab tsis siv rau cov ntawv thov hnav siab.
